The photos were taken during a severe G4 geomagnetic storm, one of the strongest in years.
We now have direct images of two supermassive black holes: M87* and Sag A*. The fact that we can capture such images is remarkable, but they might be the only black holes we can observe. That is, unless we take radio astronomy to a whole new level.
The first emergency operation in the history of China's human spaceflight program ended on Jan. 19 when an uncrewed Shenzhou 20 capsule damaged by a space-junk strike came safely down to Earth.
The Large Magellanic Cloud, or LMC, is a key spot for astronomers to study star formation.
ALMA is the most powerful radiotelescope in the world, and among its many scientific endeavours is the study of protoplanetary disks around young stars. The process of planet formation is a major theme in astronomy, and with its ability to reposition its 66 radio antennae, ALMA can zoom in on dusty protoplanetary disks and spy the early indications of exoplanet formation.
Starfish Space just scored a $52.5 million contract to deorbit satellites for the U.S. Space Force, the first deal ever signed for such "end of life" disposal services for a constellation in low Earth orbit.
The four astronauts of SpaceX's Crew-11 mission will discuss their shorter-than-expected stay aboard the International Space Station today (Jan. 21), and you can watch it live.
Material science plays an absolutely critical role in space exploration. So when a new type of self-healing composite is announced, it’s worth a look–especially when the press release specifically calls out its ability to repair microtears associated with micrometeoroid impacts on satellites. It sounds like just such a composite material was recently invented at North Carolina State University - and it’s even already been spun out into a start-up company.

Isar Aerospace's Spectrum rocket will try to become the first vehicle ever to reach orbit from European soil today (Jan. 21), and you can watch the action live.
The 18th European Space Conference (ESC) will take place on 27 and 28 January 2026 at the Square Convention Centre in Brussels, Belgium.
Just as avalanches on snowy mountains start with the movement of a small quantity of snow, the ESA-led Solar Orbiter spacecraft has discovered that a solar flare is triggered by initially weak disturbances that quickly become more violent. This rapidly evolving process creates a ‘sky’ of raining plasma blobs that continue to fall even after the flare subsides.
To land on the right foot on the Red Planet, European engineers have been dropping a skeleton of the four-legged ExoMars descent module at various speeds and heights on simulated martian surfaces.
How can scientists estimate the pH level of Enceladus’ subsurface ocean without landing on its surface? This is what a recently submitted study hopes to address as a team of scientists from Japan investigated new methods for sampling the plumes of Enceladus and provide more accurate measurements of its pH levels. This study has the potential to help scientists better understand the subsurface ocean conditions on Enceladus and whether it’s suitable for life as we know it.
Baby pictures are some of a family's most cherished artifacts. The same thing can be said of the Hubble Space Telescope and the infant stars it immortalizes in its scientific portraits. But while we know how babies are conceived and how they form in great detail, the same can't be said for star formation.
"I don't think anyone's made this connection between the surface fluid pattern and the interior properties of these planets."
Congress has rejected a draconian budget request, passing a bill that funds the space agency similarly to 2025.
Blue Origin will launch six people to the final frontier on Thursday (Jan. 22), and you can watch the space tourism mission live.
When the new WEAVE spectrograph began science operations on the 4.2 meter William Herschel Telescope (WHT) in 2023, astronomers looked forward to its first five years. During this time, the telescope will be working on eight new simultaneous surveys of the sky. Before it could begin this work, the instrument went through a science verification phase. This important step demonstrates the instrument's capabilities and allows operators to refine its operations.
The origin of super-Earths and sub-Neptunes has been revealed in a system of four young planets that are dramatically losing their thick atmospheres.
