Let's start at the beginning. Before humans, before Earth, before any of the planets existed, there were baby planets—planetesimals. Coalesced from dust exploded outward by the solar nebula, these blobs of material were ...
On Feb. 21, 2019, we shot an asteroid.
Our solar system has a king. The planet Jupiter, named for the most powerful god in the Greek pantheon, has bossed around the other planets through its gravitational influence. With twice the mass of Saturn, and 300 times ...
The Dishchii'bikoh meteorite fall in the White Mountain Apache reservation in central Arizona has given scientists a big clue to finding out where so-called LL chondrites call home. They report their results in the April ...
A model developed at the Faculty of Physics at the Technion, in collaboration with German scientists at Tübingen, explains the unique properties of Arrokoth, the most distant object ever imaged in the solar system. The research ...
What astronomers thought was a planet beyond our solar system has now seemingly vanished from sight, suggesting that what was heralded as one of the first exoplanets to ever be discovered with direct imaging likely never ...
Interstellar comet 2I/Borisov is providing a glimpse of another star system's planetary building blocks, using new observations from NASA's Hubble Space Telescope.
Impact cratering both produces new regolith and causes seismic events that can degrade and erase small craters on the surface of asteroids, a paper by Planetary Science Institute Senior Scientist James Richardson says.
The hypothesis that the solar system originated from a gigantic cloud of gas and dust was first floated in the second half of the 18th century by German philosopher Immanuel Kant and further developed by French mathematician ...
New research raises the possibility that some parts of Mercury's subsurface, and those of similar planets in the galaxy, once could have been capable of fostering prebiotic chemistry, and perhaps even simple life forms, according ...
