Four nearby white dwarf stars have been discovered hiding in plain sight beside brighter red dwarf companions. Hubble's observations finally revealed the long-hidden stellar remnants, including one just 25 light-years away.
China’s Tianwen-2 probe snapped the picture of the Earth quasi-sattelite Kamo'oalewa, after completing a landmark 1 billion-km journey that began last year. Kamo'oalewa is believed to be a piece of our own Moon.
A new analysis suggests the interstellar comet formed in the cold outer reaches of a protoplanetary disk surrounding a star far older and more metal-poor than our own.
Earth is regularly hit by space rocks we have never found. A large amount of space material hitting Earth comes from unknown, primitive asteroids that do not have representation in our meteorits collection. Micrometerites could be the missing link.
Astronomers have discovered a new Earth-like planet that might be a good candidate for habitability.
Using JWST, astronomers have just obtained humanity's first glimpse inside the atmosphere of the giant planet WD 1856b, which orbits a white dwarf – and found it far hotter than anyone expected.
For the first time, researchers say they’ve built a cell entirely from nonliving chemical ingredients that can feed, grow, and replicate.
The interstellar comet 3I/ATLAS carries a chemical fingerprint unlike anything in our Solar System, and it may have formed 10 to 12 billion years ago, before our Sun even existed, according to two papers published recently.
A compact group of at least six galaxies that are likely to merge into a single enormous system. At the heart of this cosmic construction site lies a growing supermassive black hole.
Recently, a team of scientists identified an absorption line coming from Saturn's moons Titan and Pluto that has not yet been seen anywhere else.
Its name is NGC 1052-DF9, and it's neither the first, nor the second, but the third galaxy yet whose motions can be explained without dark matter.
A team from the US and Spain has identified more than 500 deep earthquakes beneath the continent, and they are trying to find explanations that fit the data.
A new census found more active galactic nuclei in small galaxies than ever before, plus a sharp uptick in numbers as galaxy mass increases.
Astronomers have discovered salty skies surrounding the universe's famous "Pink Planet." For more than a decade, the ancient, rosy-hazed world kept astronomers guessing.
New data not only confirm the existence of two distinct populations of stars in the ancient stellar system Terzan 5, once classified as a globular cluster, but also provides evidence for two more recent rounds of star formation.
