Rare 'Radio Galaxy' NGC 612 in Sculptor | Hubble Space Telescope

Rare 'Radio Galaxy' NGC 612 in Sculptor | Hubble Space Telescope

The Hubble Space Telescope’s visible and infrared capabilities captured this edge-on view of the dusty lenticular galaxy NGC 612 with an active nucleus (type II Seyfert). It is about 400 million light-years from Earth and has a mass of around 1.1 trillion times that of our Sun. Seyfert galaxies are a class of spiral galaxies characterized by their active galactic nuclei (AGN) that emit large amounts of energy across the electromagnetic spectrum. These nuclei are powered by supermassive black holes at the center of the galaxy. They are related to quasars but involve smaller amounts of energy release.

Lenticular galaxies have a central bulge and disk much like spiral galaxies, but they lack the characteristic arms. They typically have older star populations and little ongoing star formation. 
In NGC 612, dust and cool hydrogen gas make up the majority of the galactic disc. This galaxy appears in the Sculptor constellation and is easily visible from Earth’s southern hemisphere.

NGC 612 is an active galaxy. This means that its center appears more than 100 times brighter than the combined light of its stars. It is also a Seyfert galaxy, the most common type of active galaxy. Seyfert galaxies emit large amounts of infrared radiation despite looking normal in visible light. As a Type II Seyfert, NGC 612 has matter near the center of the galaxy that moves rather calmly around the nucleus. The stars in this galaxy are unusually young with ages around 40 to 100 million years.

NGC 612 is also an extremely rare example of a non-elliptical radio galaxy, a type of galaxy that shows significant radio emissions—in this case, an association with radio source PKS 0131-36. Astronomers have only discovered five such radio-emitting lenticular galaxies in the universe. One theory attributes NGC 612’s unusual radio emissions to a past interaction with a companion spiral galaxy. Another theory focuses on the galaxy’s bright and dominant bulge. This is similar to those seen in elliptical radio galaxies. By imaging this galaxy, astronomers hope to uncover more about what causes galaxies to emit radio waves.

British astronomer John Herschel discovered NGC 612 in 1837.

Flight Deck Aurora at 37,000 feet: View over Northern Canada

Flight Deck Aurora at 37,000 feet: View over Northern Canada




Photographer Matt Melnyk: "While flying the Boeing 787 Dreamliner from Calgary, Canada, to London, UK last night, we were treated to an incredible aurora display from 37,000 feet. The aurora first became visible as we crossed northern Manitoba and continued as we flew over Hudson Bay. What started as a bright green glow developed into enormous bands and curtains of aurora stretching across the sky and directly overhead. From our altitude, the view was spectacular. With very little atmosphere or light pollution between us and the display, the stars were incredibly prominent and the aurora appeared to stretch far into the distance above the cloud-covered Earth. The show lasted for approximately three hours, giving us an extraordinary view as we continued northeast toward the Atlantic. At times, huge bands of green aurora filled much of the sky, with structure and movement clearly visible. After months of bright summer nights limiting aurora viewing on our transatlantic flights, it was fantastic to finally see the northern lights return to the night sky—and this was quite a way to welcome them back." 

Known as the northern lights (aurora borealis) or southern lights (aurora australis), auroras are colorful, dynamic, and often visually delicate displays of an intricate dance of particles and magnetism between the Sun and Earth called space weather. When energetic particles from space collide with atoms and molecules in the atmosphere, they can cause the colorful glow that we call auroras.

Canada is a country in North America. Its ten provinces and three territories extend from the Atlantic Ocean to the Pacific Ocean and northward into the Arctic Ocean, making it the second-largest country by total area with the longest coastline of any country. Its border with the United States is the longest international land border.

Odd Planetary Nebula NGC 6210 in Hercules | Hubble Space Telescope

Odd Planetary Nebula NGC 6210 in Hercules | Hubble Space Telescope

The NASA/European Space Agency Hubble Space Telescope has taken a striking high resolution image of the curious planetary nebula NGC 6210. Located about 6,500 light-years away, in the constellation of Hercules, NGC 6210 was discovered in 1825 by the German astronomer Friedrich Georg Wilhelm Struve. Although in a small telescope it appears only as a tiny disc, it is fairly bright.

NGC 6210 is the last gasp of a star slightly less massive than our Sun at the final stage of its life cycle. The multiple shells of material ejected by the dying star form a superposition of structures with various degrees of symmetry, giving NGC 6210 its odd shape. This sharp image shows the inner region of this planetary nebula in unprecedented detail, where the central star is surrounded by a thin, bluish bubble that reveals a delicate filamentary structure. This bubble is superposed onto an asymmetric, reddish gas formation where holes, filaments, and pillars are clearly visible.

The life of a star ends when the fuel available to its thermonuclear engine runs out. The estimated lifetime for a Sun-like star is about ten billion years. When the star is about to expire, it becomes unstable and ejects its outer layers, forming a planetary nebula and leaving behind a tiny, but very hot, remnant, known as white dwarf. This compact object, here visible at the center of the image, cools down and fades very slowly. Stellar evolution theory predicts that our Sun will experience the same fate as NGC 6210 in about five billion years.

This picture was created from images taken with Hubble’s Wide Field Planetary Camera 2 through three filters: the broadband filter F555W (yellow) and the narrowband filters F656N (ionized hydrogen), F658N (ionized nitrogen) and F502N (ionized oxygen). The exposure times were 80 s, 140 s, 800 s and 700 s respectively and the field of view is only about 28 arcseconds across.

'Radio Galaxy' Hercules A: Multi-wavelength view | Hubble Space Telescope

'Radio Galaxy' Hercules A: Multi-wavelength view | Hubble Space Telescope

Spectacular jets powered by the gravitational energy of a supermassive black hole in the core of the elliptical galaxy Hercules A illustrate the combined imaging power of two of astronomy's cutting-edge tools, the Hubble Space Telescope's Wide Field Camera 3, and the Karl G. Jansky Very Large Array (VLA) radio telescope in New Mexico. A radio galaxy is one with giant regions of radio emission extending well beyond its visible structure. These energetic radio lobes are powered by jets from its active galactic nucleus (AGN).

Around two billion light-years away, the yellowish elliptical galaxy in the center of the image appears quite ordinary as seen by Hubble in visible wavelengths of light. The galaxy is roughly 1,000 times more massive than the Milky Way and harbors a 2.5-billion-solar-mass central black hole that is 1,000 times more massive than the black hole in the Milky Way. However, the innocuous-looking galaxy, also known as 3C 348, has long been known as the brightest radio-emitting object in the constellation Hercules. Emitting nearly a billion times more power in radio wavelengths than our Sun, the galaxy is one of the brightest extragalactic radio sources in the entire sky.

The VLA radio data reveal enormous, optically invisible jets that, at one-and-a-half million light-years wide, dwarf the visible galaxy from which they emerge. The jets are very-high-energy plasma beams, subatomic particles and magnetic fields shot at nearly the speed of light from the vicinity of the black hole. The outer portions of both jets show unusual ring-like structures suggesting a history of multiple outbursts from the supermassive black hole at the center of the galaxy.

The innermost parts of the jets are not visible because of the extreme velocity of the material. It causes relativistic effects that beam the light away from us. Far from the galaxy, the jets become unstable and break up into the rings and wisps.

The entire radio source is surrounded by a very hot, X-ray-emitting cloud of gas, not seen in this optical-radio composite.

Hubble's view of the field also shows a companion elliptical galaxy very close to the center of the optical-radio source. It may be merging with the central galaxy. Several other elliptical and spiral galaxies that are visible in the Hubble data may be members of a cluster of galaxies. Hercules A is by far the brightest and most massive galaxy in the cluster.

Distant Elliptical Galaxy Hercules A: Black Hole-Powered Jets | NASA Chandra

Distant Elliptical Galaxy Hercules A: Black Hole-Powered Jets  | NASA Chandra

There are galaxies with extremely bright cores. This suggests that they contain a supermassive black hole that is pulling in matter at a prodigious rate. Astronomers call these "active galaxies," and Hercules A is one of them. In visible light (colored red, green and blue, with most objects appearing white), Hercules A looks like a typical elliptical galaxy. In x-ray light, however, Chandra detects a giant cloud of multimillion-degree gas (purple). This gas has been heated by energy generated by the infall of matter into a black hole at the center of Hercules A that is over 1,000 times as massive as the one in the middle of the Milky Way. Radio data (blue) show jets of particles streaming away from the black hole. The jets span a length of almost one million light years.

Hercules A is a bright radio source located over 2 billion light-years away in the constellation Hercules. This galaxy is over 1,000 times more massive than the Milky Way and contains one of the largest central supermassive black holes known. The black hole has a mass of around 4 billion solar masses.

Young RCW38 Star Cluster in Vela | NASA's Chandra X-ray Observatory

Young RCW38 Star Cluster in Vela | NASA's Chandra X-ray Observatory


A young star cluster about 5,500 light years from Earth, named RCW 38, provides astronomers a chance to closely examine many young, rapidly evolving stars at once. In this composite image, X-rays from Chandra are blue, while infrared data from NASA's Spitzer Space Telescope are orange and additional infrared data from the Two Micron All-Sky [infrared] Survey (2MASS) appears white. There are many massive stars in RCW 38 that will likely explode as supernovas. Astronomers studying RCW 38 are hoping to better understand this environment as our Sun was likely born into a similar stellar nursery.

RCW 38 is a star-forming region in the southern constellation of Vela (known as the Sails). It includes an embedded HII region and a super star cluster. H II regions are clouds of ionized hydrogen gas where new stars are actively forming, glowing due to ultraviolet radiation from young, massive stars. This is the youngest super star cluster in the Milky Way galaxy with age estimates ranging from 0.1 to 1.0 million years. It has around 10,000 member stars. The cluster member stars are still enshrouded within the dark cloud where they were born. The star cluster is surrounded by clouds of brightly glowing gas and includes many protostars. Observations by the Chandra X-ray Observatory have revealed more than 800 X-ray emitting young stellar objects in the cluster.

SpaceX Starship Booster Moved to Pad: Pre-orbital Flight 14 | Starbase Texas

SpaceX Starship Booster Moved to Pad: Pre-orbital Flight 14 | Starbase Texas




SpaceX Update: "Booster 21 moved to the pad at Starbase." 

SpaceX is preparing to go to orbit with Starship on Test Flight 14.

Follow updates and watch the event here → https://www.spacex.com/launches/starship-flight-14

The upcoming flight is planned to be the first to send Starship into orbit around Earth. Flight tests until this point have intentionally flown passively safe suborbital trajectories to maximize public safety while allowing for maximum learning. By going to orbit, the next phase of developing Starship to be fully and rapidly reusable can begin.

This will also mark the first time we plan to deploy Starlink V3 satellites into the constellation, delivering a payload that will dramatically expand connectivity speeds and reliability around the world.

Starship’s initial orbital mission is expected to fly at an altitude approximately 275 km above Earth and complete approximately six orbits around the planet over the course of a nearly 10-hour flight, with splashdown targeted in the Pacific Ocean to the west of Chile.

A live webcast of the flight will begin about 30 minutes before liftoff. Coverage is planned to continue through splashdown with the potential for hours of live views from Starship as it orbits Earth. As is the case with all developmental testing, the schedule is dynamic and likely to change, so be sure to stay tuned for updates.

The booster’s primary test objective on Flight 14 will be executing a successful launch, ascent, stage separation, boostback burn, and landing burn at an offshore landing point in the Gulf of Mexico. There have been several modifications to hardware and software to address issues seen on the previous flight.

After stage separation and flip on Flight 13, the Super Heavy booster was able to use all 33 engines on its boostback burn for the first time. In the terminal phase of the burn, the three center engines showed signs of ice clogging that triggered an early end to the maneuver. The booster went on to attempt a landing burn, with 8 of the 13 planned engines reigniting before the booster made a hard splashdown in the Gulf. The Super Heavy on this upcoming flight has hardware modifications to improve filtering to the engines and software changes to enhance relight reliability.

The Starship upper stage’s primary objectives include the first orbital insertion maneuver, the deployment of 26 Starlink V3 satellites, a deorbit burn using a single Raptor engine while in space, and a controlled reentry, descent, and splashdown in the Pacific Ocean. Starship will only execute a burn to enter orbit after the flight control team has ensured there is sufficient redundancy on hardware critical to doing the subsequent deorbit burn at the end of the mission.

Starship will deliver 26 Starlink V3 satellites to orbit for the first time. They aim to greatly expand the network's capacity and user speeds. Each Starlink V3 satellite will add 1 Tbps of capacity to the constellation, for a total of 26 Tbps of capacity added on this mission alone. That’s ~10x the capacity compared to a single launch of V2 mini Starlink satellites on Falcon 9.

After deploying from Starship, the Starlink V3 satellites will unfold their antennas and deploy their solar arrays and make initial contact with the ground and the rest of the Starlink constellation via radio frequency and laser links. The satellites will then begin raising their orbits with their onboard thrusters. Following their on-orbit checkouts, the satellites should begin serving customers as soon as a few weeks after launch.

Three of the satellites have been modified with a suite of cameras to scan Starship’s heatshield and transmit imagery down to operators to continue testing methods of analyzing Starship’s heatshield readiness for return to launch site on future missions.

Several upgrades and experiments related to Starship’s heatshield will also be tested, with some improvements derived directly from data gathered from the Flight 13 Starship as it floated in the Indian Ocean. They include additional retention mechanisms added to tiles in areas deemed to be at highest risk of falling off during ascent, addressing recently discovered areas that offer flow paths behind tiles for plasma, and flying multiple areas with a curved tile design that has shown the ability to reduce heating in the gaps between tiles. And finally, two tiles recovered from Ship 40 are planned to be reflown on Ship 41, marking the first tile reuse for Starship.

NASA plans to use a lunar lander version of Starship to deliver astronauts and cargo to the Moon during the Artemis IV mission and beyond through the Human Landing System (HLS) Program.

Behind the Scenes: China CAS Space Lijian-1 Rocket Launches 9 Satellites

Behind the Scenes: China CAS Space Lijian-1 Rocket Launches 9 Satellites

China successfully launched nine satellites,  including the Qinling-1, Qinling-2, and PEGA-SUS1, from the Dongfeng Commercial Space Innovation Pilot Zone in northwest China at 12:03 (Beijing Time) Sunday, September 20, 2026.

The satellites were carried by a Lijian-1 Y18 carrier rocket and have entered their planned orbits.

The Lijian-1 (Kinetica-1), developed by Chinese commercial space company CAS Space, is a solid-fuel carrier rocket featuring rapid-response capabilities.

The launch mission was a complete success. This launch was the 16th launch for Kinetica-1, and the 17th for CAS Space through its Kinetica family of launch vehicles. This was also the 68th launch from China in 2026.

This Kinetica-1 flight brought the start of another orbital computing constellation into space, and a communication-computing spacecraft demonstrator, alongside seven satellites designed to look back at Earth.

The Chaozhisuan-1 satellite is to be the first of a constellation to be deployed under the same name, of potentially thousands of spacecraft under an alliance established in March 2026 with notable members being Zhipu AI, SenseTime, Beijing Wenge Technology Co. Ltd. and Tsinghua University.

Peng Cheng Laboratory and the Southern University of Science and Technology, both based in Shenzhen, had their GalaxySpace-made 150-kilogram PEGA-SUS1 multi-purpose demonstrator satellite placed into orbit. From space, the satellite will verify its ability to serve as a 5G non-terrestrial network base station, demonstrate a 100 gigabits per second optical laser communication link, and prove artificial intelligence-enabled data processing provided by onboard compute. If it can prove all three, involved companies hope that it will open the way for further integration of space-based communications and computing.

Developed by entities under the Shanghai Academy of Spaceflight Technology (SAST), the Pujiang-4 carbon dioxide and methane emission monitoring satellite was deployed. This satellite will keep watch of known, and highlight abnormal, emission sources found within a 30-kilometer-wide observation area. Monitoring is mainly planned to be conducted on sources within China, to help meet climate goals, but global sources can be observed, also.

A niche trio of satellites launched among the rest is Diting-1A, 1B, and 1C designed to monitor electromagnetic frequencies and their emitting locations for a variety of customers. The trio is operated by Tianjin Xingkan Jiuzhou Technology, while being produced by Changguang Satellite Technology Co. Ltd.

Lastly, there is ‘Yunxiao Pathfinder Satellite' reported to be tasked with remote sensing. The satellite belongs to the Institute of Mechanics, Chinese Academy of Sciences.

Preparing for Lunar South Pole Science Investigations | NASA Artemis Program




Trevor Graff, the Artemis Science Team Hardware and Testing Lead, can be seen deploying a mockup of the Lunar Environment Monitoring Station (LEMS) during testing with the Active Response Gravity Offload System (ARGOS) at NASA's Johnson Space Center in Houston, Texas. LEMS is a compact, autonomous, and self-sustaining seismometer suite designed to carry out continuous, long-term, monitoring of the lunar seismic environment at the South Polar region. The instrument will characterize the regional structure of the Moon’s crust and mantle. This will add valuable information to lunar formation and evolution models. 

LEMS can operate autonomously and sustainably for years at the Moon to collect geophysical measurements continuously during lunar days and nights. LEMS is intended to operate on the lunar surface from three months up to two years and may become a key station in a future global lunar geophysical network.

During NASA's Artemis IV Mission in 2028, landers will bring astronauts to the lunar surface—this time to stay.

Spiral Galaxy NGC 4045 in Virgo | Subaru Telescope

Spiral Galaxy NGC 4045 in Virgo | Subaru Telescope

The spiral galaxy NGC 4045, located in the Virgo constellation, displays two distinct spiral arms extending from its bright central nucleus to its outer regions. A faint blue spiral arm stretches to the right, indicating that stars are actively forming in the outer regions of this galaxy.

Distance from Earth: ~110 million light-years

Below NGC 4045 lies another galaxy, NGC 4045 A. Although it appears close enough to be gravitationally interacting with NGC 4045, it is actually a far more distant galaxy aligned along the same line of sight from Earth, and the two galaxies are not physically associated.

NGC 4045 was discovered by German-British astronomer William Herschel on December 20, 1784. It was also observed by German astronomer Heinrich Louis d'Arrest on April 10, 1863, causing it to be listed a second time in the New General Catalog, as NGC 4046.

Light-toned Deposits in Melas Chasma | NASA's Mars Reconnaissance Orbiter

Light-toned Deposits in Melas Chasma | NASA's Mars Reconnaissance Orbiter

Melas Chasma is a canyon on Mars, the widest segment of the Valles Marineris canyon system, located east of Ius Chasma at 9.8°S, 283.6°E in the Coprates quadrangle. It cuts through layered deposits that are thought to be sediments from an old lake that resulted from runoff of the valley networks to the west.

It has been known since the 1970s when the Viking orbiters took pictures of Mars that there are large (i.e., several kilometers-thick) mounds of light-toned deposits within the central portion of Valles Marineris. More recent higher resolution images of Mars, including this image of Melas Chasma, show that the wall rocks of Valles Mariners also contain similar, albeit thinner, light-toned deposits.

Spectral data from the Mars Reconnaissance Orbiter's Compact Reconnaissance Imaging Spectrometer for Mars (CRISM) instrument indicate that the larger mounds are composed of sulfates. A portion of the wall rock deposits are also made up of sulfates, but others contain clays or mixtures of several kinds of hydrated materials, suggesting that multiple aqueous processes within Valles Marineris, formed the variety of deposits we now observe.

This HiRISE enhanced color camera image (less than 1 km in size) was captured by NASA's Mars Reconnaissance Orbiter (MRO) at an altitude of 265 km  (~165 miles).

NASA's Mars Reconnaissance Orbiter has spent over twenty years (2006-2026) orbiting the Red Planet, collecting valuable scientific data.

The University of Arizona, in Tucson, operates the High Resolution Imaging Science Experiment (HiRISE). It was built by BAE Systems in Boulder, Colorado.

China CAS Space Lijian-1 Rocket Launches 9 Satellites

China CAS Space Lijian-1 Rocket Launches 9 Satellites

China successfully launched nine satellites,  including the Qinling-1, Qinling-2, and PEGA-SUS1, from the Dongfeng Commercial Space Innovation Pilot Zone in northwest China at 12:03 (Beijing Time) Sunday, September 20, 2026.

The satellites were carried by a Lijian-1 Y18 carrier rocket and have entered their planned orbits.

The Lijian-1 (Kinetica-1), developed by Chinese commercial space company CAS Space, is a solid-fuel carrier rocket featuring rapid-response capabilities.

The launch mission was a complete success. This launch was the 16th launch for Kinetica-1, and the 17th for CAS Space through its Kinetica family of launch vehicles. This was also the 68th launch from China in 2026.

This Kinetica-1 flight brought the start of another orbital computing constellation into space, and a communication-computing spacecraft demonstrator, alongside seven satellites designed to look back at Earth.

The Chaozhisuan-1 satellite is to be the first of a constellation to be deployed under the same name, of potentially thousands of spacecraft under an alliance established in March 2026 with notable members being Zhipu AI, SenseTime, Beijing Wenge Technology Co. Ltd. and Tsinghua University.

Peng Cheng Laboratory and the Southern University of Science and Technology, both based in Shenzhen, had their GalaxySpace-made 150-kilogram PEGA-SUS1 multi-purpose demonstrator satellite placed into orbit. From space, the satellite will verify its ability to serve as a 5G non-terrestrial network base station, demonstrate a 100 gigabits per second optical laser communication link, and prove artificial intelligence-enabled data processing provided by onboard compute. If it can prove all three, involved companies hope that it will open the way for further integration of space-based communications and computing.

Developed by entities under the Shanghai Academy of Spaceflight Technology (SAST), the Pujiang-4 carbon dioxide and methane emission monitoring satellite was deployed. This satellite will keep watch of known, and highlight abnormal, emission sources found within a 30-kilometer-wide observation area. Monitoring is mainly planned to be conducted on sources within China, to help meet climate goals, but global sources can be observed, also.

NASA Artemis III Rocket Booster Stacking | Kennedy Space Center

NASA Artemis III Rocket Booster Stacking | Kennedy Space Center









Technicians can be seen here integrating the booster segments for NASA’s Artemis III Space Launch System (SLS) rocket atop the mobile launcher in High Bay 3 of the Vehicle Assembly Building at NASA’s Kennedy Space Center in Florida. The SLS rocket’s twin boosters, each made up of five segments manufactured by Northrop Grumman in Utah, will provide more than 75 percent of the rocket’s total thrust at launch. The Artemis III Mission will launch crew in the Orion spacecraft on top of the SLS rocket to test rendezvous and docking capabilities between Orion and commercial spacecraft needed to land astronauts on the Moon.

Planned to launch in 2027, the Artemis III Mission will practice docking the Orion spacecraft with two lunar landers in low Earth orbit. 

On future missions, including Artemis IV in 2028, landers will bring astronauts to the lunar surface. While Artemis III will not land on the Moon, it will test the complex capabilities NASA needs to return—this time to stay.
