Pan of Spiral Galaxy NGC 3810 in Leo | Hubble

Measuring the distance to truly remote objects like galaxies, quasars and galaxy clusters is a crucial task in astrophysics, particularly when it comes to studying the early Universe. However, it is a difficult one. Only in the case of a few nearby objects like the Sun, planets and nearby stars can we measure their distances directly. Beyond that, indirect methods need to be used. One of the most important is by examining Type Ia supernovae. This is where the NASA/European Space Agency Hubble Space Telescope comes in.

Distance: 50 million light years

NGC 3810, the galaxy featured in this image, was the host of a Type Ia supernova in 2022. In early 2023 Hubble focused on this and a number of other galaxies to closely examine recent Type Ia supernovae. This kind of supernova results from a white dwarf exploding, and they all have a very consistent brightness. It allows them to be used to measure distances. We know how bright a Type Ia supernova should be, so we can tell how far away it must be from how dim it appears. One uncertainty in this method is that intergalactic dust in between Earth and a supernova blocks a portion of its light. 

How much of the reduction in light is caused by distance, and how much by dust? With the help of Hubble, there is a clever workaround. We can take images of the same Type Ia supernovae in ultraviolet light, almost completely blocked by dust, and in infrared light that passes through dust almost unaffected. By carefully noting how much light comes through at each wavelength, the relationship between supernova brightness and distance can be calibrated to account for dust. Hubble can observe these wavelengths of light in great detail with the same instrument. This makes it the perfect tool for this experiment, and indeed, the data is used to make this beautiful image of NGC 3810. You can see 2022 supernova as a point of light just below the galactic nucleus and in the annotated image.

There are many ways to measure cosmic distances; because Type Ia supernovae are so bright, they are one of the most useful and accurate tools, when they are identified. Many other methods must be used as well, either as an independent check against other distance measurements or to measure at much closer or farther distances. One such method that also works for galaxies is comparing their rotation speed to their brightness; based on that method, NGC 3810 is found to be 50 million light-years from Earth.

Image Description: A spiral galaxy seen almost face-on. Large spiral arms whirl out from its center, filling the scene. They glow faintly blue from the stars within. There are small bright patches of blue and pink marking areas of star formation. They are overlaid with thin filaments of dark reddish dust that block light. The galaxy’s center shines brightly white.

Cometary Globules of Interstellar Gas & Dust in Puppis & Vela

Cometary Globules of Interstellar Gas & Dust in Puppis & Vela

What are these unusual interstellar structures? Bright-rimmed, flowing shapes gather near the center of this rich starfield toward the borders of the nautical southern constellations Puppis and Vela. Composed of interstellar gas and dust. This grouping of light-year sized cometary globules is about 1,300 light-years distant. 

Energetic ultraviolet light from nearby hot stars has molded the globules and ionized their bright rims. The globules also stream away from the Vela supernova remnant. This may have influenced their swept-back shapes. Within them, cores of cold gas and dust are likely collapsing to form low mass stars. Their formation will ultimately cause the globules to disperse. In fact, cometary globule CG 30 (on the upper left) sports a small reddish glow near its head, a telltale sign of energetic jets from a star in the early stages of formation.

Kitt Peak National Observatory Discovers Extremely Strange Orbit of Rare Exoplanet

Kitt Peak National Observatory Discovers Extremely Strange Orbit of Rare Exoplanet

Using the WIYN 3.5-meter telescope at the U.S. National Science Foundation's Kitt Peak National Observatory, a Program of the National Science Foundation's NOIRLab, astronomers have discovered the extreme orbit of an exoplanet that is on its way to becoming a "hot Jupiter". This exoplanet not only follows one of the most drastically stretched-out orbits of all known transiting exoplanets but is also orbiting its star backwards, lending insight into the mystery of how hot Jupiters evolve.

Planets that are more than twice the diameter of Earth have about ten Earth masses and enough gravity to hold onto hydrogen, the most abundant element in the Universe. Such large planets turn into gas giants like Jupiter and Saturn. Jupiter is more than ten times the diameter of Earth and more than 300 times the mass of Earth. Most of the 300 plus exoplanets that have been detected so far are gas giants. However, unlike Jupiter that is five times as far from the Sun as Earth, exoplanets, referred to as "hot Jupiters", are much closer to their stars than Earth is to the Sun.

NASA Artemis II Moon Rocket Core Stage Loaded onto Pegasus Barge

NASA Artemis II Moon Rocket Core Stage Loaded onto Pegasus Barge

The NASA Michoud Assembly Facility workforce and with other agency team members take a “family photo” with the SLS (Space Launch System) core stage for Artemis II in the background. 

These images show team members at Michoud Assembly Facility loading the first core stage that will help launch the first crewed flight of NASA’s Space Launch System (SLS) rocket for the agency’s Artemis II mission onto the Pegasus barge on Tuesday, July 16, 2024. The barge will ferry the core stage on a 900-mile journey from the agency’s Michoud Assembly Facility in New Orleans to its Kennedy Space Center in Florida.

The core stage for the SLS mega rocket is the largest stage NASA has ever produced. At 212 feet tall, the stage consists of five major elements, including two huge propellant tanks that collectively hold more than 733,000 gallons of super chilled liquid propellant to feed four RS-25 engines at its base. During launch and flight, the stage will operate for just over eight minutes, producing more than 2 million pounds of thrust to help send a crew of four astronauts inside NASA’s Orion spacecraft onward to the Moon. All the major structures for every SLS core stage are fully manufactured at NASA Michoud.

NASA is working to land the first woman, first person of color, and its first international partner astronaut on the Moon under Artemis. SLS is part of NASA’s backbone for deep space exploration, along with the Orion spacecraft and Gateway in orbit around the Moon and commercial human landing systems, next-generation space, next-generational spacesuits, and rovers on the lunar surface. SLS is the only rocket that can send Orion, astronauts, and supplies to the Moon in a single launch.

Strong X1.9 Solar Flare Erupts from Sun | NASA’s Solar Dynamics Observatory

Strong X1.9 Solar Flare Erupts from Sun | NASA’s Solar Dynamics Observatory

The Sun emitted a strong solar flare, peaking at 9:26 A.M. ET on July 16, 2024. NASA’s Solar Dynamics Observatory, watching the Sun constantly, captured an image of the event. It came  from departing active (sunspot) region 3738. The flare was associated with radio signatures that suggest a coronal mass ejection (CME) was likely associated with this activity, but due to its far southwestern location, an Earth-directed one is not anticipated.

The Sun, shown in gold, against a black background. On the right is a bright white flash, on the limb of the star. The Sun has swirls of bright gold and darker gold regions, and one very large, dark black splotch toward the top called a coronal hole.

NASA’s Solar Dynamics Observatory captured this image of a solar flare—seen as the bright flash on the right—on July 16, 2024. The image shows a subset of extreme ultraviolet light that highlights the extremely hot material in flares. It is colorized in gold.

Solar flares are powerful bursts of energy. Flares and solar eruptions can impact radio communications, electric power grids, navigation signals, and pose risks to spacecraft and astronauts.

This flare is classified as an X1.9 (R3-Strong) flare. X-class denotes the most intense flares, while the number provides more information about its strength.

Shenzhou-18 Astronauts: Second Spacewalk Photos | China Space Station

Shenzhou-18 Astronauts: Second Spacewalk Photos | China Space Station

The Shenzhou-18 astronauts aboard China's orbiting space station completed their second spacewalk on Wednesday, July 4, 2024, according to the China Manned Space Agency (CMSA).

Ye Guangfu, Li Cong, and Li Guangsu worked for about 6.5 hours to accomplish multiple tasks with Li Guangsu remaining inside the space station.

With the assistance of the space station's robotic arm and researchers on Earth, they installed space debris protection devices for the pipelines, as well as cables and key equipment outside the Tiangong space station, and conducted an extravehicular inspection.

"The main purpose of the spacewalk this time is to install protection devices for extravehicular equipment, mainly cables and pipelines, so as to improve the space station's ability to operate safely and steadily over the long term," said Liu Ming, an engineer with the China Aerospace Science and Technology Corporation (CASC).

After installing protection devices, Li Cong mounted the robotic arm and conducted an extravehicular inspection of the space station's facilities through his helmet camera.

After completing the predetermined tasks, Ye Guangfu and Li Cong returned safely to the Wentian lab module.

"The Chinese space station is very beautiful. Whenever the robotic arm moves to the highest point, I can't help taking more glances at the space station despite the glaring sunlight. I really feel the greatness of the project from my heart, and I applaud all the space professionals and our motherland. We will make continuous efforts to successfully and efficiently complete the follow-up tasks to the end. Let's meet again inside the cabin," Li Cong said outside the space station.

In their previous spacewalk on May 28, the Shenzhou-18 trio mainly installed protection devices for the extravehicular cables of the Mengtian lab module.

The Shenzhou-18 crew, sent to the space on April 25 this year, have completed one third of their space journey and are scheduled to carry out a large amount of in-orbit scientific experiments and technological tests, the agency said.

Northrop Grumman Cygnus Cargo Ship Departure | International Space Station

Northrop Grumman Cygnus Cargo Ship Departure | International Space Station

On July 12, 2024, the S.S. Patricia “Patty” Hilliard Robertson Northrop Grumman Cygnus spacecraft was released from the Canadarm2 robotic arm. It had detached Cygnus from the Earth-facing port of the International Space Station’s Unity module earlier. At the time of release, the station was flying about 260 miles over the South Atlantic Ocean.

The Cygnus spacecraft successfully departed the International Space Station more than five and a half months after arriving at the microgravity laboratory to deliver about 8,200 pounds of supplies, scientific investigations, commercial products, hardware, and other cargo for NASA.

The Kentucky Re-entry Probe Experiment-2 (KREPE-2), stowed inside Cygnus, later recorded measurements to demonstrate a thermal protection system for spacecraft and their contents during re-entry in Earth’s atmosphere. This can be difficult to replicate in ground simulations.

Following a deorbit engine firing on Saturday, July 13, Cygnus began its planned destructive re-entry. The spacecraft—filled with trash packed by the station crew—"safely burn up" in Earth’s atmosphere.

Cygnus arrived at the space station Feb. 1, following a launch on a SpaceX Falcon 9 rocket from Space Launch Complex 40 at Cape Canaveral in Florida. It was the company’s 20th commercial resupply services mission to the International Space Station for NASA. The spacecraft is named the S.S. Patricia “Patty” Hilliard Robertson in honor of the former NASA astronaut.

The Sun: Abundant Sunspot Activity | NASA’s Solar Dynamics Observatory

The Sun: Abundant Sunspot Activity | NASA’s Solar Dynamics Observatory

An abundance of sunspot groups are present on the visible solar disk—at least 12 active regions. Sunspots are areas that appear dark on the surface of the Sun. They appear dark because they are cooler than other parts of the Sun’s surface. Solar flares are a sudden explosion of energy caused by tangling, crossing, or reorganizing of magnetic field lines near sunspots. The southern solar hemisphere has the most and largest sunspot complexes at this time, to include the most likely flare sources: Regions 3738, 3743, and 3751. Region 3738 is the most magnetically complex, but growth has slowed and it will rotate out to the western solar limb by Wednesday, July 17, 2024.

R1-R2 (Minor-Moderate) solar flares remain likely between July 15-18, 2024.  

NASA’s Solar Dynamics Observatory captured these images of sunspot activity on July 13, 2024. Solar flares are powerful bursts of energy. Flares and solar eruptions can impact radio communications, electric power grids, navigation signals, and pose risks to spacecraft and astronauts.
