Glowing bridge links dwarf galaxies in stunning new image from the James Webb Space Telescope
A spectacular new view of two dwarf galaxies caught in the middle of a cosmic collision reveals a glowing gas bridge, streams of newborn stars and the ongoing gravitational tug-of-war reshaping both galaxies.
‘Hubble tension’ is back again as a new cosmic map deepens the puzzle
"It means cleaning house, narrowing the viable paths forward, and no longer spending energy on what are evidently dead ends."
Scientists discover one of our universe’s largest spinning structures — a 50-million-light-year-long cosmic thread
The discovery potentially transforms what we think about how the cosmic environment influences galaxies as they form.
Rare solar flare caused radiation in Earth’s atmosphere to spike to highest levels in nearly 20 years, researchers say
Levels of potentially dangerous cosmic radiation in Earth's atmosphere rose to a two-decade high in November after a rare solar super-flare pummeled the planet with high-speed particles from the sun.
Rare images reveal active sunspots minutes before they unleashed powerful X-flares that caused November 2025’s stunning auroras
We don't often get a good look at X-class solar flares from ground-based observatories.
Europe picks companies to help build Argonaut moon lander
Europe's plans to develop its "Argonaut" robotic moon lander are moving ahead with the announcement of an Italy-led consortium that will build a key element of the spacecraft.

The vantage point at Cerro Pachón, with its dark skies and high-altitude clarity, enhances the richness of the image.
A ‘super-puff’ exoplanet is losing its atmosphere, and the James Webb Space Telescope had a look
Astronomers have spotted a distant world "shedding" its atmosphere into space in real time, creating a giant cloud of helium gas that sweeps across its parent star well before the planet itself.
NASA discovers ‘space gum’ and sugars ‘crucial to life’ in asteroid Bennu samples brought to Earth (video)
Asteroid Bennu samples contain life-friendly sugars, a strange "space-gum," and ancient stardust
