The Shape of a Black Hole
Black holes are already strange enough, regions of space where gravity is so extreme that not even light can escape. But physicists have long known there's another layer of weirdness, that black holes also behave like thermodynamic objects, with temperature, entropy, and phase transitions just like a gas or a liquid. Now, a new approach borrowed from pure mathematics is revealing hidden patterns in that behaviour and hinting at something fundamental about the nature of black holes themselves.
Written in Rock
A small rock found in the African desert has just handed scientists an extraordinary window into one of the most violent and consequential periods in the history of the Solar System. Inside this lunar meteorite, a chunk of the Moon knocked to Earth by an ancient collision, researchers have found evidence of a massive impact event 3.5 billion years ago, one that matches the timing of known impacts on Earth and in the asteroid belt. Three worlds but one shared bombardment and a story that may have everything to do with the origins of life.
Titan's Hidden Blanket
Saturn's moon Titan has long fascinated scientists, it’s a world with rivers, lakes, and a thick atmosphere, all made not of water but of methane. Now, a new study suggests Titan is stranger than first imagined since beneath its surface lies a 9 km thick crust of methane laced ice that acts like a giant thermal blanket, warming the interior in ways nobody expected.

NASA’s Chandra Discovers Possible Supernova Remnant in Galactic Center
Using data from NASA’s Chandra X-ray Observatory, astronomers may have found a supernova remnant in an intriguing neighborhood in the middle of our galaxy. A paper describing these new findings published in The Astrophysical Journal.
Supernova remnants are the expanding remains of exploded stars and provide elements – like iron, oxygen, and silicon – that are critical for the formation of planets and for life as we know it to form and flourish.
This new supernova remnant, if confirmed, would be one of the closest ever discovered to the supermassive black hole at the central region of the Milky Way galaxy, an exotic region crammed with massive stars, long threads of magnetic fields and dense clouds of gas orbiting rapidly around the Galactic Center.
Astronomers may have uncovered a new supernova remnant in a star-forming region near the center of the Milky Way galaxy using data from Chandra and XMM-Newton. If confirmed, this would be one of the closest supernova remnants to the supermassive black hole in the Galactic Center. This image shows the region where the evidence was found, which contains X-rays from Chandra and XMM-Newton, radio data from the MeerKAT telescope in South Africa, and an optical image from the Pan-STARRS telescopes in Hawaii. X-ray: NASA/CXC/UCLA/Z. Zhu et al.; ESA/XMM-Newton; Optical: PanSTARRS; Radio: MeerKAT; Infrared (JWST): NASA/ESA/CSA/STScI; Image Processing: NASA/CXC/SAO/L. Frattare and P. Edmonds
A new composite image of this region contains X-rays from Chandra and ESA’s (European Space Agency’s) XMM-Newton mission (shown in blue) as well as radio data from the MeerKAT telescope (shown in red) in South Africa. These have been combined with an optical image from the Pan-STARRS telescopes in Hawaii (red, green, and blue). The plane of the galaxy runs horizontally from left to right in the image, and the central black hole is off to the left of the image.
The evidence for the new supernova remnant, located about 26,000 light-years from Earth, comes from X-ray data from Chandra and XMM-Newton. The X-ray data reveals a “blob” of X-ray emission that may come from the remains of a massive star that self-destructed as a supernova, buried within the larger cloud of expanding gas.
The location of this suspected supernova remnant in the image is labeled with a circle.
It is in a bubble of gas that has had electrons stripped away from hydrogen – called an “H II region” – surrounding a massive, young star. This bubble is a bright source of radio emission called Sagittarius C.
If this is indeed a supernova remnant, then it is expanding at about two million miles per hour and is at least about 1,700 years old. Previously, observations with NASA’s now-retired SOFIA (Stratospheric Observatory for Infrared Astronomy) mission had shown evidence for an expanding shell of gas surrounding Sagittarius C. This gave astronomers a hint that a stellar explosion had occurred in the same spot.
The long filaments seen in the radio image are caused by energetic particles travelling along magnetic fields that are mostly directed perpendicular to the plane of the galaxy.
The nuclear fusion engines of stars create elements from hydrogen and helium that were abundant at the beginning of the universe. When stars explode at the end of their lives as supernovae, they send these newly synthesized elements into interstellar space and provide material for the next generation of stars and planets.
The team of astronomers searched the X-ray data for signs of increased amounts of key elements in the remnant, which would have been caused by the stellar explosion blasting them into space. While they did not see an enhancement, this could imply that the stellar debris has already mixed with the surrounding gas.
An alternative explanation for the X-ray blob is that the hot gas comes from a collection of massive stars in the region. The authors of the recent study don’t think this explanation is likely, because the X-ray emission from the blob is more than ten times brighter than the X-ray emission of large, known stellar clusters with bright, massive stars.
An additional image shows data from NASA’s James Webb Space Telescope added to the X-ray and radio data. The light blue color represents infrared light from gas in the H II region, and the darker blue depicts X-rays from the supernova remnant candidate, on the right side of the image. X-rays near the center of the image are associated with the H II region, possibly caused by material blown away by massive stars that has heated gas to millions of degrees, producing X-rays.

Visual DescriptionThis release features a composite image of colorful, overlapping clouds, which suggests to astronomers that a supernova remnant may be buried in gas near the center of our Milky Way galaxy.
Set against a backdrop packed with distant stars and other specks of light are two distinct, overlapping clouds. The larger, visually dominant cloud, is red and multifaceted. It has an irregular shape, and features patches of different textures, including pockets that resemble wispy smoke, tangles of faint red veins, and clear streaking lines. This large cloud of expanding gas represents radio data from the MeerKAT telescope in South Africa.
Overlapping with that red cloud is a cloudy blue blob representing X-ray data from NASA’s Chandra X-ray Observatory and ESA’s XMM-Newton. Astronomers suggest that this blue blob of X-ray emissions is the remains of a massive star destroyed by a supernova.

I Am Artemis: Elkin Norena
Listen to this audio excerpt from Elkin Norena, resident management officer, NASA’s Space Launch System Program:
0:00 / 0:00
Your browser does not support the audio element.NASA’s Elkin Norena has helped the agency launch more than a dozen space shuttle missions – that’s more than a dozen crews to low Earth orbit and more than a dozen historic missions. They were missions that helped build the International Space Station, that provided a final servicing mission to the Hubble Space Telescope, and that performed critical science experiments that improved life right here on Earth.
Today, he continues that work as the manager of the Resident Management Office for SLS at NASA’s Kennedy Space Center in Florida, helping launch America’s rocket – the SLS (Space Launch System) – and the Orion spacecraft with its international quartet of astronauts on the Artemis II mission to fly by the Moon and return home.

As resident manager, Norena provides onsite SLS support for NASA’s Exploration Ground Systems team that is responsible for preparing, stacking, testing, and launching SLS and Orion. He is also the eyes and ears for the SLS Program, providing an avenue of communications back to the program, which is managed at NASA’s Marshall Space Flight Center in Huntsville, Alabama.
It is the continuation of a childhood dream to be part of space exploration.
“When I was a kid in New Jersey, I watched a space shuttle launch in class one day,” said Norena. “When I watched the power of launch and the brave astronauts going to explore, I knew I had to be a part of that one day. I wanted to become an astronaut.”
The dream to join the space program led the Colombia native to the University of Central Florida in Orlando, where he majored in computer engineering, just miles from the Space Coast and in view of space shuttle launches like the ones he once watched on TV.
When that clock ticks down to T-10 minutes, everybody’s just waiting. You wait for the automated system to kick in. You hold your breath and watch the clock go down to T-0. Then BOOM, launch happens, and you know it was all worth it.Elkin Norena
Resident management officer, NASA Space Launch System Program
Following college, he joined NASA contractor United Space Alliance at NASA Kennedy, and in 2008 he joined the NASA Kennedy team as a civil servant, working on the same spacecraft that inspired him to pursue the space program as a child.
“I started off in the Space Shuttle Program as an electrical engineer. Then I moved into the firing room for 17 different shuttle missions as a flight termination engineer. It was exciting to be part of all those missions and build the International Space Station,” Norena said.

Using those experiences, he became one of the original SLS team members. He was a part of the teams that successfully launched Artemis I and II and is now critical to the upcoming Artemis III mission.
Away from the launch pad, Norena’s hobbies orbit around his teenage daughters, participating in their activities. He also keeps a keen eye on space and is an avid astrophotographer.
“I love capturing the Milky Way! I’ve traveled to Utah, New Mexico, Arizona, and all across the western United States,” he said. “A great spot that’s closer for me is Dry Tortugas National Park beyond Key West.”
No matter how he explores space, Norena believes Artemis II is more than just a mission.
“This is historic. I grew up watching the shuttle missions, learning about Apollo, and wanting to be part of those Moon missions. We built the space station. The space shuttle explored space and technology on many levels,” he said. “Now, it’s our turn with Artemis to get back to the Moon, and this time to stay there. I’m excited to be part of the generation that does that.”

NASA Robotic Tech Demo Will Advance Prototype Gamma-Ray Detectors

NASA Robotic Tech Demo Will Advance Prototype Gamma-Ray DetectorsA new type of gamma-ray sensor developed by NASA, called AstroPix, will take part in a robotic arm demonstration on the agency’s upcoming Fly Foundational Robots mission, set to launch in late 2027.
Gamma rays are the highest-energy form of light. Scientists observe them coming from events like lightning in Earth’s atmosphere, powerful solar flares from our Sun, and cosmic collisions in distant galaxies. The sensors on the AstroPix technology demonstration are designed to measure gamma rays between 20,000 and 700,000 electron volts. For comparison, visible light’s energy falls between 2 and 3 electron volts.
Current NASA missions, including the Fermi Gamma-ray Space Telescope and Neil Gehrels Swift Observatory, also observe gamma rays, including those with even higher energies.
But for energies between 500,000 to 1 million electron volts, existing detectors are less sensitive. This range is where many powerful explosions called gamma-ray bursts shine the brightest. It’s also where astronomers expect to see the strongest glow from the most massive and distant active galaxies powered by black holes. By stacking AstroPix detectors in future missions, scientists could bridge this gap and improve observations of these cosmic objects to better understand the processes that create and drive them.
“The Fly Foundational Robots spacecraft is also a technology demonstration, so the projects were a good fit for each other,” said Dan Violette, an AstroPix team member and post-doctoral fellow at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. “We need to thoroughly test AstroPix’s performance before we can use the sensors in future science missions. We’ve flown comparable technologies on a scientific balloon mission, and the current prototype eventually will be part of a sounding rocket payload. Many of those flight opportunities only reach near space, though. It’s not often that technology demonstrations like ours can find a ride into orbit.”
Each AstroPix chip has four silicon pixel gamma-ray detectors. Each of these detectors incorporates 1,225 pixels. AstroPix detectors, which are developed by NASA’s Goddard Space Flight Center in Greenbelt, Md., function similarly to the sensors in cellphone cameras except they are sensitive to gamma-ray light.

Each AstroPix chip contains four silicon pixel gamma-ray detectors, and each detector incorporates 1,225 pixels. The chips function similarly to the sensors in cell phone cameras.
The AstroPix Satellite Technology dEmonstration Payload, also known as A-STEP, will be hosted within the Fly Foundational Robots mission’s Orbital Replacement Unit, a movable module built by Rocket Lab Robotics. Rocket Lab Robotics also will provide a robotic arm that will pick up and reposition the unit during flight and perform in-orbit operations as part of a robotic servicing demonstration. The A-STEP payload will collect its data following the repositioning. Astro Digital will provide the spacecraft.
The Orbital Replacement Unit was designed to support power and data interfaces for a payload, but the original plan called for the robotic arm to reposition the module without one. As mission development progressed, however, the Fly Foundational Robots team identified an opportunity to further maximize the mission’s value by integrating an additional technology demonstration that could fit within the 11.8-inch (30-centimeter) cube.
“The unit already had the volume, power, and data needed to support the AstroPix team’s design,” said Bo Naasz, senior technical lead, In-space Servicing, Assembly, and Manufacturing in the Space Technology Mission Directorate at NASA Headquarters in Washington. “One of our major goals with Fly Foundational Robots is to demonstrate robotic changeout of payloads in orbit, enabling upgrades or improvements to satellites and space instruments at a fraction of the cost of a full mission. Allowing AstroPix to complete its own technology demonstration in orbit is a bonus.”
NASA’s Fly Foundational Robots mission will be hosted aboard a spacecraft provided by Astro Digital of Littleton, Colo., as shown in this artist’s concept. The robotic arm, provided by Motiv Space Systems in Pasadena, Calif., will perform a technology demonstration in orbit, including picking up and moving a small box containing the agency’s AstroPix gamma-ray sensors. Rocket Lab Robotics
The AstroPix team is working to deliver their hardware this September, and it will be integrated into the Fly Foundational Robots payload before final integration onto the spacecraft. The Orbital Replacement Unit will hold the chips and all the associated electronics needed to provide power, and collect and transmit data during flight.
NASA’s Fly Foundational Robots mission is funded through the Space Technology Mission Directorate’s ISAM portfolio, managed at NASA Goddard. Rocket Lab Robotics will supply the mission’s robotic arm system through a NASA Small Business Innovation Research Phase III award. Astro Digital will host the orbital flight test of the arm through NASA’s Flight Opportunities program, managed at NASA’s Armstrong Flight Research Center in Edwards, California. The development of AstroPix was supported by NASA’s Astrophysics Division in the Science Mission Directorate at NASA Headquarters, through the agency’s Astrophysics Research and Analysis Program, and funded through the Nancy Grace Roman Technology Fellowship.
