A supernova and its host galaxy are the subject of this NASA/ESA Hubble Space Telescope image. The galaxy in question is LEDA 132905 in the constellation Sculptor. Even at more than 400 million light-years away, LEDA 132905’s spiral structure is faintly visible, as are patches of bright blue stars.
The bright pinkish-white dot in the center of the image, between the bright center of the galaxy and its faint left edge, is a supernova named SN 2022abvt. Discovered in late 2022, Hubble observed SN 2022abvt about two months later. This image uses data from a study of Type Ia supernovae, which occur when the exposed core of a dead star ignites in a sudden, destructive burst of nuclear fusion. Researchers are interested in this type of supernova because they can use them to measure precise distances to other galaxies.
The universe is a big place, and supernova explosions are fleeting. How is it possible to be in the right place at the right time to catch a supernova when it happens? Today, robotic telescopes that continuously scan the night sky discover most supernovae. The Asteroid Terrestrial-impact Last Alert System, or ATLAS, spotted SN 2022abvt. As the name suggests, ATLAS tracks down the faint, fast-moving signals from asteroids close to Earth. In addition to searching out asteroids, ATLAS also keeps tabs on objects that brighten or fade suddenly, like supernovae, variable stars, and galactic centers powered by hungry black holes.

NASA astronaut Don Pettit aboard the International Space Station. (Credit: NASA) For the first time, NASA is hosting a live Twitch event from about 250 miles off the Earth aboard the International Space Station, bringing new audiences closer to space than ever before. Viewers will have the opportunity to hear from NASA astronauts live and ask questions about life in orbit.
The event will begin at 11:45 a.m. EST on Wednesday, Feb. 12, livestreamed on the agency’s official Twitch channel:
https://www.twitch.tv/nasa
“This Twitch event from space is the first of many,” said Brittany Brown, director, Office of Communications Digital and Technology Division, at NASA Headquarters in Washington. “We spoke with digital creators at TwitchCon about their desire for streams designed with their communities in mind, and we listened. In addition to our spacewalks, launches, and landings, we’ll host more Twitch-exclusive streams like this one. Twitch is one of the many digital platforms we use to reach new audiences and get them excited about all things space.”
Although NASA has streamed events to Twitch previously, this conversation will be the first NASA event from the International Space Station developed specifically for the agency’s Twitch platform.
During the event, viewers will hear from NASA astronaut Don Pettit, who is currently aboard the orbiting laboratory, and NASA astronaut Matt Dominick, who recently returned to Earth after the agency’s Crew-8 mission.
The NASA astronauts will discuss daily life aboard the space station and the research conducted in microgravity. Additionally, the event will highlight ways for Twitch users to engage with NASA, including citizen science projects and science, technology, engineering, and math programs designed to inspire the Artemis Generation.
NASA is committed to exploring new digital platforms to engage with new audiences. Last year, the agency introduced its own streaming platform, NASA+, and redesigned nasa.gov and science.nasa.gov websites, creating a new homebase for agency news, Artemis information, and more.

Engineers and technicians with NASA’s Exploration Ground Systems Program integrate the right forward center segment onto mobile launcher 1 inside the Vehicle Assembly Building at NASA’s Kennedy Space Center in Florida on Wednesday, Jan. 22, 2025. The boosters will help support the remaining rocket components and the Orion spacecraft during final assembly of the Artemis II Moon rocket and provide more than 75 percent of the total SLS (Space Launch System) thrust during liftoff from NASA Kennedy’s Launch Pad 39BNASA/Kim Shiflett Teams with NASA’s Exploration Ground Systems Program continue stacking the SLS (Space Launch System) rocket’s twin solid rocket booster motor segments for the agency’s Artemis II mission, inside the Vehicle Assembly Building (VAB) at NASA’s Kennedy Space Center in Florida.
Currently, six of the 10 segments are secured atop mobile launcher 1 with the right forward center segment as the latest addition. Teams will continue integrating the booster stack – the left center center segment adorned with the NASA “worm” insignia is the next segment to be integrated.
The right and left forward assemblies were brought to the VAB from the spaceport’s Booster Fabrication Facility on Jan. 14. The forward assemblies are comprised of three parts: the nose cone which serves as the aerodynamic fairing; a forward skirt, which house avionics; and the frustum which houses motors that separates the boosters from the SLS core stage during flight. The remaining booster segments will be transported from the Rotation, Processing, and Surge Facility to the VAB when engineers are ready to integrate them. The forward assemblies will be the last segments integrated to complete the booster configuration, ahead of integration with the core stage.

Jon Carabello has spent his entire career at TURBOCAM, which produces 10 core stage main engine turbomachinery components for the RS-25 main engine on NASA’s SLS (Space Launch System) heavy lift exploration rocket.Photo: TURBOCAM Jon Carabello did not begin his career journey with an eye on space, but when NASA’s Artemis lunar exploration campaign came calling, he was all in.
Born, raised, and college-educated in New Hampshire, Carabello has spent his entire professional career at TURBOCAM – a turbomachinery development and manufacturing company – in the southeast corner of the Granite State.
That’s a long way from the southern and western states commonly associated with U.S. human spaceflight activities.
Asked about his early memories of America’s space program, Carabello mentions movies like Apollo 13, and notes that Christa McAulliffe, the teacher-astronaut who died in the 1986 Space Shuttle Challenger accident, taught high school in New Hampshire.
Little did he know that his future employer, a maker of complex machined hardware for a variety of industrial applications, has long been a component supplier to programs including the Space Shuttle and the International Space Station.
There was never much question that Carabello, who started tinkering with engines and other machinery at a young age, would make a career of mechanical engineering. “I like to solve problems – that’s my big thing,” he says.
He learned about TURBOCAM when company representatives made a presentation to his University of New Hampshire engineering class. “That’s how I figured out I knew wanted to work at TURBOCAM and work with 5-axis machining,” he says. “Machining amazes me.”
Five axis machine tools can machine metal blanks from multiple angles to create geometrically complex parts for industrial hardware. TURBOCAM produces 10 core stage main engine turbomachinery components for the RS-25 main engine on NASA’s SLS (Space Launch System) heavy lift exploration rocket. L3Harris Technologies is the prime contractor for the RS-25 engines.
It was his fascination with machining rather than the opportunity to work on rocket engines that drew Carabello to TURBOCAM, where he initially worked on machinery for the oil and gas industry, heating and air conditioning systems, and aerospace.
But then one day, a supervisor asked him to take over the company’s RS-25 portfolio. He remembers the conversion quite clearly.
“It was a Thursday afternoon,” he says. “I was sitting in my office and my manager came in and said, ‘we have somebody leaving and need someone to take over project management and ownership of the RS-25.’ I said, ‘yes’ and he said, ‘you have a call with the program tomorrow.’ That was about five years ago.”
It was a significant change, but Carabello knew the company needed his problem-solving skills on the RS-25 program. “I know how to bring a team together to deliver a quality product. It’s rewarding to know I’m helping return humans to the Moon and paving the way to Mars with the Artemis campaign.”
Self-confidence notwithstanding, Carabello admits to being a bit nervous given that NASA astronauts will be relying on his work. That point was driven home when NASA and L3Harris representatives visited TURBOCAM in the spring of 2024 for a series of presentations on Artemis. The remark that resonated with him the most was by NASA astronaut Dr. Lee Morin, who said the most important part of any human spaceflight mission is bringing astronauts safely home.
“That meant a lot to me,” says Carabello, whose team is responsible for all aspects of TURBOCAM’S RS-25 effort, including quality control, inspection, and resource allocation. He is constantly reminding his team of what’s really at stake for astronauts bound for space: “We’re helping them to return home,” he says.
