Researchers have just announced a spectacular new discovery for Vera Rubin Observatory – the telescope's first candidate dwarf planet, a large object in the Kuiper Belt some 600 to 1,500 km across.
One ultra-short period exoplanet named TOI-561 b has an atmosphere made of volatiles like water and carbon dioxide.
Crowded star clusters in the early Universe could have built giant stars, seeded black holes and fed the mysterious little red dots.
There's also a growing understanding that rocky planets form with a primordial envelope rich in hydrogen and helium that they acquire from their solar nebulae.
Virgin Galactic is back in the spaceflight spotlight with the unveiling of a shiny new object: an updated Delta-class suborbital space plane with an exotic name, Apeiron.
Hubble’s first visible-light view of the Cat’s Tail near Beta Pictoris offers clues to a possible collision between two large icy worlds.
Comets traveled too fast and struck at unfavorable angles for the fragile molecules needed for life to survive, making successful delivery extraordinarily unlikely.
Astronomers may have just made another milestone discovery in the search for intrinsically intriguing worlds: the hottest star to potentially host a habitable-zone planet, a giant world named HD 156295 b.
From the direction of K2-155, a red dwarf some 238 light-years away, came a narrowband radio signal that survived the researchers' initial attempts to weed out interference – that's a type of radio signal that can be difficult to produce without technology.
Now, for the first time, scientists have detected radio signals coming directly from one of these planets, a massive gas giant named β Pictoris b.
A new research suggests that planets may also be born later, from the debris of a dying star, and one such unique alien world may be sitting very close to HS 0209+0832, a hot, young white dwarf located 270 light-years away.
This fast radio burst, designated FRB 20240304B, is the most distant ever detected, having traveled more than 10 billion years across the cosmos to reach Earth.
A signal was found in isolation in the southern constellation of Fornax. There was no other emission line accompanying it – and in prior observations from Hubble and JWST, nothing else could be seen in that patch of space.
Researchers have found evidence that the Sun's mass loss will not be smooth but turbulent and random, ejected in thousands of individual "kicks".
Powerful jets from supermassive black holes can disturb star-forming gas far beyond a galaxy’s visible edge, leaving a glowing trail hundreds of thousands of light-years long.
