One of SpaceX's Starlink broadband satellites suffered an anomaly in orbit on Wednesday (Dec. 17) that led to its partial breakup, according to the company.

"It's like looking back in time in a sense, to that violent period of our solar system when it was less than a billion years old."
Nature sends us its signals in the form of light. Astrophysical phenomena emit light in all its forms, from harmless radio waves to deadly gamma-rays, and its up to us to build the facilities that can sense and dissect this light, and to understand the phenomena behind it all.
Interstellar visitor 3I/ATLAS is travelling away from the sun on its way back to interstellar space.
The JWST was built with the power to observe the red-shifted light from objects in the very early Universe. Once it got going, the telescope practically inundated us with surprising, theory-challenging observations from the Universe's earliest ages. Some ancient galaxies were much larger and fully-formed than thought. So were their supermassive black holes (SMBH).

Watch the replay of the media information session in which ESA Director General Josef Aschbacher and ESA Council Chair Renato Krpoun (CH) update journalists on key decisions taken at the ESA Council meeting, held at ESA Headquarters in Paris on 17 and 18 December 2025.
Satellites would likely begin colliding with each other or space junk in less than three days if they were to lose the ability to maneuver, for example due to an intense solar storm.
A rare interstellar comet has been caught in X-rays by two space telescopes, revealing how its gases interact with charged particles from the sun as it travels through the inner solar system.
With new technologies comes new discoveries. Or so Spider Man’s Uncle Ben might have said if he was an astronomer. Or a scientist more generally - but in astronomy that saying is more true than many other disciplines, as many discoveries are entirely dependent on the technology - the telescope, imager, or processing algorithm - used to collect data on them. A new piece of technology, the Nancy Grace Roman Space Telescope, is exciting scientists enough that they are even starting to predict what kind of discoveries it might make. One such type of discovery, described in a pre-print paper on arXiv by Vito Saggese of the Italian National Institute for Astrophysics and his co-authors on the Roman Galactic Exoplanet Survey Project Infrastructure Team, is the discovery of many more multiplantery exoplanet systems an astronomical phenomena Roman is well placed to detect - microlensing.
2025 was another busy year on the sun. But how did it compare with 2024, and what will 2026 bring for solar activity and the northern lights?
