The Dorado Group of Galaxies | Euclid Space Telescope

The Dorado Group of Galaxies | Euclid Space Telescope

The Dorado Group of galaxies is one of the richest galaxy groups in the southern hemisphere. Here, the European Space Agency's Euclid space telescope captures signs of galaxies evolving and merging ‘in action’, with beautiful tidal tails and shells visible as a result of ongoing interactions. Since Dorado is a lot younger than other clusters (like Fornax), several of its constituent galaxies are still forming stars and remain in the stage of interacting with one another, while others show signs of having merged relatively recently. In size, it sits between larger galaxy clusters and smaller galaxy groups, making it a useful and fascinating object to study with Euclid. The Dorado Group lies 62 million light-years away in the constellation of Dorado.

This dataset is enabling scientists to study how galaxies evolve and collide over time in order to improve our models of cosmic history and understand how galaxies form within halos of dark matter. This new image demonstrates Euclid’s versatility. A wide array of galaxies is visible here, from very bright to very faint. Thanks to Euclid’s unique combination of large field-of-view and high spatial resolution, for the first time we can use the same instrument and observations to deeply study tiny (small objects the size of star clusters), wider (the central parts of a galaxy) and extended (tidal merger tails) features over a large part of the sky.

Scientists are also using Euclid observations of the Dorado Group to answer questions that previously could only be explored using painstakingly small snippets of data. This includes compiling a full list of the individual clusters of stars (globular clusters) around the galaxies seen here. Once we know where these clusters are, we can use them to trace how the galaxies formed and study their history and contents. Scientists will also use these data to hunt for new dwarf galaxies around the Group, as it did previously with the Perseus cluster.

Galaxy NGC 6744’s Disrupted Spiral Arm | Euclid Space Telescope

Galaxy NGC 6744’s Disrupted Spiral Arm | Euclid Space Telescope

This image from the European Space Agency’s Euclid space telescope is a higher resolution, close-up cutout from a larger frame featuring the spiral galaxy NGC 6744. This frame shows one of the galaxy’s disrupted spiral arms, a result of a recent interaction with the companion dwarf galaxy seen to the right. This interaction caused massive, hot stars to form, as marked by patches of blue.

Image Description: Hundreds of stars and galaxies are spread over this image against a dark sky. A stream of stars veiled by a thin fog-like substance curves from a cloud in the bottom to the upper right. At the end of this stream of stars sits a cloudy ellipse. A bright yellow star with eight diffraction spikes emerges from a cloud in the bottom of the image.

Close-up View of Bright Star near Abell 2764 | Euclid Space Telescope | ESA

This image from the European Space Agency’s Euclid space telescope is a smaller, close-up cutout from a larger frame featuring the galaxy cluster Abell 2764. It focuses on a bright star lying near to the cluster: V*BP-Phoenicis/HD 1973, a star within our galaxy and in the southern hemisphere that is nearly bright enough to be seen by the human eye. Euclid’s design and observing capabilities mean that the space telescope can observe very faint objects lying very close to such bright stars without being blinded by the ambient starlight.

Image Description: Hundreds of stars and galaxies are spread over this image against a dark sky. One very big bright star sits in the left of the image. This star has six diffraction spikes coming from a central light-halo. The rest of the image has tiny dot-like stars, and some elliptical galaxies can be distinguished as bright haloes around even brighter dots.

Close-up View: Stellar Nursery Messier 78 | Euclid Space Telescope | ESA

Close-up View: Stellar Nursery Messier 78 | Euclid Space Telescope | ESA

This new image from the European Space Agency’s Euclid space mission is a higher resolution, close-up cutout from a larger frame featuring Messier 78, a vibrant nursery of star formation enveloped in a shroud of interstellar dust, and its surroundings. Messier 78 lies 1,300 light-years away in the constellation of Orion within our Milky Way galaxy. 

The image illustrates how newly forming stars create a 'cavity' in the surrounding molecular cloud by generating winds of charged particles. The colors relate to ionized atomic hydrogen (the main component of the cloud; blue) and the absorption and scattering of light by dust grains (red).

Image Description: The image shows hundreds of stars with a number brighter than others. The stars seem to light up their cloud-like surroundings in purple. A darker structure spans the image in an arch from upper left to bottom right. The bottom of this arch runs into dense clouds forming the darkest part of the image.

Star-forming Region Messier 78 | Euclid Space Telescope | ESA

Star-forming Region Messier 78 | Euclid Space Telescope | ESA

This new Euclid space telescope image from the European Space Agency features the Messier 78 reflection nebula (the central and brightest region), a vibrant nursery of star formation enveloped in a shroud of interstellar dust. The image is the first of this young star-forming region at this width and depth. Messier 78 lies 1,300 light-years away in the constellation of Orion within our Milky Way galaxy. 

Euclid has used its infrared camera to expose hidden regions of star formation for the first time, mapping Messier 78's complex filaments of gas and dust in detail. This is the first time we have been able to see smaller, sub-stellar sized objects in Messier 78; the dark clouds of gas and dust usually hide them from view, but Euclid’s infrared ‘eyes’ can see through these obscuring clouds to explore within.

Euclid’s sensitive instruments can detect objects just a few times the mass of Jupiter, and its visible and infrared instruments—the visible instrument (VIS) and Near Infrared Spectrometer and Photometer (NISP) cameras—reveal over 300,000 new objects in this field of view alone. Scientists are using this data to study the amount and ratio of stars and sub-stellar objects here. This is the key to understanding the dynamics of how star populations form and change over time. Sub-stellar objects like brown dwarfs and free-floating or ‘rogue’ planets are also one possible candidate for dark matter. While our current knowledge suggests that there are not enough of these objects to solve the mystery of dark matter in the Milky Way, it remains an open question, and one that Euclid seeks to answer by probing a significant fraction of our galaxy.

Also visible to the top of the frame is the bright nebula NGC 2071, and a third filament of star formation towards the bottom of the image (with a ‘traffic light’-like appearance). This lower region is a dark nebula producing lower-mass stars, all arranged along elongated filaments in space.

Image Description: A filamentary orange veil covers a bright region of star formation. The background is dark, stippled with stars and galaxies ranging from small bright dots to starry shapes. The foreground veil spans from upper left to the bottom right and resembles a seahorse. Bright stars light up the ‘eye’ and ‘chest’ regions of the seahorse with purple light. Within the tail, three bright spots sit in a traffic-light like formation.

A Tour of Galaxy Pictor A's 'Death Star' Black Hole | NASA Chandra

A Tour of Galaxy Pictor A's 'Death Star' Black Hole | NASA Chandra


The Universe produces phenomena that often surpass what science fiction can conjure.

The Star Wars franchise has featured the fictitious "Death Star." It can shoot powerful beams of radiation across space. The Universe, however, produces phenomena that often surpass what science fiction can conjure.

The Pictor A galaxy is one such impressive object. This galaxy, located nearly 500 million light years from Earth, contains a supermassive black hole at its center. A huge amount of gravitational energy is released as material swirls towards the event horizon, the point of no return for infalling material. This energy produces an enormous beam, or jet, of particles traveling at nearly the speed of light into intergalactic space. A giant jet spanning continuously for over 570,000 light years is seen blasting out of the galaxy Pictor A. By comparison, the entire Milky Way is about 100,000 light years in diameter. Because of its relative proximity and Chandra's ability to make detailed X-ray images, scientists can look at detailed features in the jet and test ideas of how the X-ray emission is produced.

To obtain images of this jet, scientists used NASA's Chandra X-ray Observatory at various times over 15 years. Chandra's X-ray data (blue) have been combined with radio data from the Australia Telescope Compact Array (red) in this new composite image.

By studying the details of the structure seen in X-rays and radio waves, scientists seek to gain a deeper understanding of these huge collimated blasts.

In addition to the prominent jet seen pointing to the right in the image, researchers report evidence for another jet pointing in the opposite direction, known as a "counterjet". While tentative evidence for this counterjet had been previously reported, these new Chandra data confirm its existence. The relative faintness of the counterjet compared to the jet is likely due to the motion of the counterjet away from the line of sight to the Earth.

The detailed properties of the jet and counterjet observed with Chandra show that their X-ray emission likely comes from electrons spiraling around magnetic field lines, a process called synchrotron emission. In this case, the electrons must be continuously re-accelerated as they move out along the jet. How this occurs is not well understood

The researchers ruled out a different mechanism for producing the jet's X-ray emission. In that scenario, electrons flying away from the black hole in the jet at near the speed of light move through the sea of cosmic background radiation (CMB) left over from the hot early phase of the Universe after the Big Bang. When a fast-moving electron collides with one of these CMB photons, it can boost the photon's energy up into the X-ray band.

The X-ray brightness of the jet depends on the power in the beam of electrons and the intensity of the background radiation. The relative brightness of the X-rays coming from the jet and counterjet in Pictor A do not match what is expected in this process involving the CMB, and effectively eliminate it as the source of the X-ray production in the jet.

'Death Star' Black Holes in Action | NASA’s Chandra X-ray Observatory

'Death Star' Black Holes in Action | NASA’s Chandra X-ray Observatory

Huge black holes are firing powerful beams of particles into space—and then changing their aim to fire at new targets. This discovery, made using NASA’s Chandra X-ray Observatory and the Very Long Baseline Array, shows what kind of widespread impact black holes can have on their surrounding galaxy and beyond.

A team of astronomers looked at 16 black holes in galaxies surrounded by hot gas detected in X-rays by Chandra. Using radio data, they studied the directions of beams—also known as jets—of particles fired a few light-years away from the black holes. This gave the scientists a picture of where each beam is currently pointed, as seen from Earth. Each black hole fires two beams in opposite directions.

The team then used Chandra data to study pairs of cavities, or bubbles, in the hot gas that were created in the past by the beams pushing gas outwards. The locations of large outer cavities indicate the pointing direction of beams millions of years earlier. The researchers then compared the directions of the radio beams with the directions of the pairs of cavities.

They found that about a third of the beams are now pointing in completely different directions than before. These so-called death star black holes are swiveling around and pointing at new targets.

The X-ray and radio data indicate that the beams can change directions over nearly 90 degrees in some cases, and over timescales between one million years and a few tens of millions of years. Considering that these black holes are likely more than 10 billion years old, astronomers consider a large change in direction over a few million years to be fast.

Scientists think that beams from black holes and the cavities they carve out play an important role in how many stars form in their galaxies. The beams pump energy into the hot gas in and around the galaxy, preventing it from cooling down enough to form huge numbers of new stars. If the beams change directions by large amounts, they can tamp down star formation across much larger areas of the galaxy.

NASA Earth Science PREFIRE Mission | Rocket Lab Launch Preparations

NASA Earth Science PREFIRE Mission | Rocket Lab Launch Preparations









NASA’s PREFIRE mission aims to improve global climate change predictions by expanding our understanding of heat loss at the polar regions. The Polar Radiant Energy in the Far-InfraRed Experiment (PREFIRE) will send two shoebox-size satellites into space to study the Arctic and Antarctic. They will be the first to systematically measure heat in the form of far-infrared radiation emitted from those regions. Launch of both cubesats on two Rocket Lab Electron rockets is planned no earlier than May 25, 2024 from Launch Complex 1 (LC-1)—a commercial rocket launch facility located at Māhia Peninsula, on the east coast of New Zealand's North Island.

Earth absorbs much of the Sun’s energy at the tropics. Weather and ocean currents then move that heat toward the poles, which help regulate Earth’s climate by radiating that heat back into space. However, the Arctic is warming about three times faster than anywhere else on Earth. This is leading to increased ice sheet melt and sea level rise in coastal communities. The data from PREFIRE will help scientists better understand how Earth’s polar regions respond to climate change and what that might mean for the future.

To prepare for exploring the Moon during NASA’s Artemis campaign, the agency is conducting a week-long field test in the lunar-like landscape of San Francisco Volcanic Field near Flagstaff, Arizona to practice moonwalk scenarios.

NASA astronauts Kate Rubins and Andre Douglas are serving as the crewmembers and wearing mockup spacesuit systems as they traverse through the desert, completing a variety of technology demonstrations, hardware checkouts and Artemis science-related operations. 

During the test, two integrated teams will work together as they practice end-to-end lunar operations. The field team consists of astronauts, NASA engineers, and field experts in the Arizona desert conducting the simulated moonwalks, while a team of flight controllers and scientists at NASA’s Johnson Space Center in Houston monitor and guide their activities.

“Field tests play a critical role in helping us test all of the systems, hardware, and technology we’ll need to conduct successful lunar operations during Artemis missions,” said Barbara Janoiko, director for the field test at Johnson. “Our engineering and science teams have worked together seamlessly to ensure we are prepared every step of the way for when astronauts step foot on the Moon again.”   

The test consists of four simulated moonwalks that follow operations planned for Artemis III and beyond, as well as six advanced technology runs. During the advanced runs, teams will demonstrate technology that may be used for future Artemis missions, such as display and navigation data stream capabilities in the form of a heads-up display using augmented reality or lighting beacons that could help guide crew back to the lander. 

Ahead of the field test, the science team at Johnson that was competitively selected and tasked with developing the science objectives for the field test, followed a planning process designed for Artemis missions. Their preparation included generating geologic maps, a list of science questions, and prioritized moonwalk locations for both the primary and back-up “landing sites” for the test. 

“During Artemis III, the astronauts will be our science operators on the lunar surface with an entire science team supporting them from here on Earth,” said Cherie Achilles, science officer for the test at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. “This simulation gives us an opportunity to practice conducting geology from afar in real time.” 

The test will evaluate gaps and challenges associated with lunar South Pole operations, including data collection and communications between the flight control team and science team in Houston for rapid decision-making protocols. 

At the conclusion of each simulated moonwalk, the science team, flight control team, crewmembers, and field experts will come together to discuss and record lessons learned. NASA will take these lessons and apply them to operations for NASA’s Artemis missions, commercial vendor development, and other technology development. 

This field test is the fifth in the series conducted by the Joint Extravehicular Activity and Human Surface Mobility Test Team led out of Johnson. This test expands on previous field tests the team has performed and is the highest fidelity Artemis moonwalk mission simulation to date. 

NASA uses field tests to simulate missions to prepare for deep space destinations. The Arizona desert has been a training ground for lunar exploration since the Apollo era because of the many similarities to the lunar terrain, including craters, faults and volcanic features. 

Through Artemis, NASA will land the first woman, the first person of color, and its first international partner astronaut on the Moon, paving the way for long-term lunar exploration and serving as a steppingstone for astronaut missions to Mars.

The Roman Coronagraph, the most powerful coronagraph ever flown in space, will block the light from host stars, allowing scientists to directly observe exoplanets, or worlds beyond our solar system. 

The coronagraph is a technology demonstration that will show how this cutting-edge technology can work in space. These types of technologies will be necessary for future missions like NASA’s proposed Habitable Worlds Observatory mission concept.

Night Time-lapse: Extremely Large Telescope under Construction in Chile | ESO

This time-lapse shows the dome of European Southern Observatory’s Extremely Large Telescope (ELT), under construction in Chile’s Atacama Desert, from sunset on April 3, 2024 to sunrise the next day.

A multi-layered cladding is being installed over the dome’s steel skeleton—it will thermally insulate the telescope structure to protect it from the extreme desert environment and help regulate the air temperature. Over the telescope, the stunning night sky shows the Milky Way band and the Magellanic Clouds. Towards the end of the clip, the Moon rises in the east before a new day begins.

When finished, the dome will weigh in at 6,100 tonnes, and it will need a mind-boggling 30 million bolts to be held together. This huge structure will shelter the telescope during observations, protecting it from the elements. The entire behemoth will rotate on 36 stationary trolleys, allowing astronomers to observe the southern sky from just about any direction they fancy. The current largest optical telescopes have diameters of up to ten meters, and the ELT's diameter will thus be four times greater. 

Altitude: 3046 meters

Planned year of technical first light: 2027
