The European Space Agency's XMM-Newton is playing a crucial role in investigating the longest and most energetic bursts of X-rays seen from a newly awakened black hole. Watching this strange behaviour unfold in real time offers a unique opportunity to learn more about these powerful events and the mysterious behaviour of massive black holes.

Sols 4498-4499: Flexing Our Arm Once Again
NASA’s Mars rover Curiosity acquired this image using its Left Navigation Camera on March 30, 2025 — Sol 4496, or Martian day 4,496 of the Mars Science Laboratory mission — at 20:12:48 UTC. NASA/JPL-Caltech Written by Conor Hayes, Graduate Student at York University
Earth planning date: Monday, March 31, 2025
Planning today began with two pieces of great news. First, our 50-meter drive (about 164 feet) from the weekend plan completed successfully, bringing us oh-so-close to finally driving out of the small canyon that we’ve been traversing through and toward the “boxwork” structures to our southwest. Second, we passed our “Slip Risk Assessment Process” (SRAP), confirming that all six of Curiosity’s wheels are parked firmly on solid ground. Avid readers of this blog will be familiar with last week’s SRAP challenges, which prevented us from using the rover’s arm for the entire week. With a green light on SRAP, we were finally able to put our suite of contact science instruments back to work today.
The arm gets to work early on the first sol of this plan, with an APXS integration on “Los Osos,” a bedrock target in our workspace, after it has been cleared of the ubiquitous Martian dust by DRT. The rest of our arm activities consist of a series of MAHLI observations later in the afternoon, both of Los Osos and “Black Star Canyon.”
Of course, just because we managed to get contact science in this plan doesn’t mean we’re letting our remote sensing instruments take a break. In fact, we have more than two hours of remote sensing, split between the two sols and the two science teams (Geology and Mineralogy [GEO] and Atmosphere and Environment [ENV]). GEO will be using Mastcam to survey both the highs and the lows of the terrain, with mosaics of “Devil’s Gate” (some stratigraphy in a nearby ledge) and some small troughs close to the rover. We’ll also be getting even more Mastcam images of “Gould Mesa,” an imaging target in many previous plans, as we continue to drive past it. ChemCam gets involved with a LIBS observation of “Fishbowls,” which will also be imaged by Mastcam, a post-drive AEGIS, and two RMI mosaics of Gould Mesa and “Torote Bowl,” which was also imaged over the weekend.
ENV’s activities are fairly typical for this time of year as Curiosity monitors the development of the Aphelion Cloud Belt (ACB) with several Navcam cloud movies, as well as seasonal changes in the amount of dust in and above Gale with Navcam line-of-sight observations and Mastcam taus. We’ll also be taking a Navcam dust devil movie to see if we can catch any cold-weather wind-driven dust movement. ENV also filled this plan with their usual set of REMS, RAD, and DAN observations.
The drive planned today is significantly shorter than the one over the weekend, at just about 10 meters (about 33 feet). This is because we’re driving up a small ridge, which limits our ability to see what’s on the other side. Although our rover knows how to keep itself safe, we still prefer not to drive through terrain that we can’t see in advance, if it can be avoided. Once we’ve got a better eye on what lies in front of us, we will hopefully be able to continue our speedy trek toward the boxwork structures.

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.

With ESA’s EarthCARE satellite and four measuring instruments all working extremely well and fully commissioned, the mission’s ‘first level’ data stream is now freely available.
By combining data from all four instruments, scientists ultimately aim to address a critical Earth science question: how do clouds and aerosols affect the heating and cooling of our atmosphere?
