Long before scientists discovered that other stars in the Universe host their own planetary systems, humanity had contemplated the existence of life beyond Earth. As our technology matured and we began monitoring the night sky in multiple wavelengths (i.e., radio waves), this curiosity became a genuine scientific pursuit. By the 1960s, a scientific field dedicated to the search for advanced life (similar to ours) emerged: the Search for Extraterrestrial Intelligence (SETI). Since then, multiple SETI surveys have been conducted to search for potential signs of technological activity (aka. "technosignatures").

Did Astronomers Just Find a ‘Superkilonova’ Double Explosion? Maybe.
Astronomers may have just seen the first ever ‘superkilonova,’ a combination of a supernova and a kilonova. These are two very different kinds of stellar explosions, and if this discovery stands, it could change the way scientists understand stellar birth and death.
Trump signs sweeping executive order aimed at 'ensuring American space superiority'
On Thursday (Dec. 18), President Donald Trump issued an executive order designed to ensure American space superiority. It calls for the initial construction of a moon base by 2030, among other goals.
Why are the 'Avatar' movies so massive? Their success seems to defy conventional logic
They're not part of a vast, Marvel-style universe, and neither is a classic. So why are the "Avatar" movies so successful?

A SpaceX Starlink satellite is tumbling and falling out of space after partial breakup in orbit
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.

Astronomers capture 1st direct images of collisions in a nearby star system: 'It's like looking back in time'
"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."
Luminous Fast Blue Optical Transients Are Likely Large Black Holes Shredding Their Massive Companions
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.
4 ways to track 3I/ATLAS without a telescope as it makes its closest approach to Earth tonight
Interstellar visitor 3I/ATLAS is travelling away from the sun on its way back to interstellar space.
The JWST Found A Jekyll-and-Hyde Galaxy In The Early Universe
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).
342nd Council: Media information session
Video: 00:00:00
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.
'Crash Clock' reveals how soon satellite collisions would occur after a severe solar storm — and it's pretty scary
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.
Scientists detect X-ray glow from interstellar comet 3I/ATLAS extending 250,000 miles into space
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.
Using Bent Light to Map Complex Planetary Architectures
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.
