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.
Consciousness may arise not just in the biological tissue we find on Earth, but potentially in radically different physical materials found elsewhere in the cosmos.
