At least 75 % of Earth’s mass appears to originate from two protoplanets, that grew large by accreting pebbles, while planetesimals contributed up to 25 %. In contrast, roughly three-quarters of Mars’ mass appears to come from planetesimals.
NASA’s Curiosity rover drove sent a captivating panorama from the slopes of Mount Sharp. The image was not white-balance adjusted during processing, to show just what a viewer might really see at sunrise standing on Mars.
About 1% of neutron stars have even stronger magnetic fields. Known as magnetars, their magnetic fields can be 1,000 times stronger than a regular magnetic field. A new study looks at how magnetars might form.
New research suggests that some unusual characteristics of the Sun may be explained if it swallowed a large planet sometime during the Solar System’s formation.
According to a new study, Mercury's surface has been shrinking 10% to 30% (up to 23 km) faster than previously thought.
The simulations show that the Little Red Dots are black holes growing at a rate that would be impossible today thanks to the conditions in the early Universe.
Astronomers have confirmed a Jupiter-size planet less than a million years old, making Elias 2-24 b the youngest known planet.
Astronomers have found new evidence that 3I/ATLAS, only the third confirmed interstellar object ever detected entering the Solar System from beyond, formed in an extremely cold environment far from any star.
The researchers named them hypersoft X-ray sources. The team found between 7 and 21 sources in each of six galaxies, including Andromeda and M101.
Holes and pitted ground on Mars are nothing new. But the new holes Curiosity has found - tiny, shallow divots in the ground – are unlike anything seen before on Mars.
A new research suggests that there's a single important ingredient to happiness: freedom. Or, more specifically, whether we feel like we are actually in charge of our own lives.
Recent observations with NASA’s Hubble Space Telescope have revealed a giant, evolving, 10-sided atmospheric wave encircling Saturn's south pole.
Researchers running the LUX-ZEPLIN (LZ) dark matter experiment have recorded a single particle interaction that can’t be explained by any known background signals from normal matter.
Roman will be a discovery machine that will bring us closer than ever before to answering humanity’s most profound questions about our cosmic history.
A new data from NASA’s Hubble Space Telescope shows definitive evidence of yet another dwarf galaxy merging with the young Milky Way galaxy in the earliest phases of its evolution.
