The study of near-Earth asteroids (NEAs) is driven by both scientific and practical reasons. Because of their proximity to our planet, they can provide key information regarding the delivery of water and organic-rich material ...
When astronomers use the NASA/ESA Hubble Space Telescope to study the deep sky, asteroids from our solar system can leave their marks on the captured pictures of far-away galaxies or nebulae. But rather than be annoyed at ...
Scientists have discovered how water molecules can be regenerated on asteroids moving through space, in an exciting breakthrough that could extend to other bodies such as the moon.
Stars are born in the midst of large clouds of gas and dust. Local densifications first form "embryos," which then collect matter and grow. But how exactly does this accretion process work? And what happens when two stars ...
When a new NASA space telescope opens its eyes in the mid-2020s, it will peer at the universe through some of the most sophisticated sunglasses ever designed.
Something mysterious happened nearly half a billion years ago that triggered one of the most important changes in the history of life on Earth. Suddenly, there was an explosion of species, with the biodiversity of invertebrate ...
The metallic asteroid Psyche has mystified scientists because it is less dense than it should be, given its iron-nickel composition. Now, a new theory could explain Psyche's low density and metallic surface.
Last December, scientists discovered an "active" asteroid within the asteroid belt, sandwiched between the orbits of Mars and Jupiter. The space rock, designated by astronomers as 6478 Gault, appeared to be leaving two trails ...
When "Oumuamua crossed Earth's orbit on October 19th, 2017, it became the first interstellar object ever to be observed by humans. These and subsequent observations, rather than dispelling the mystery of "Oumuamua's true ...
Astronomers have discovered a planet three times the mass of Jupiter that travels on a long, egg-shaped path around its star. If this planet were somehow placed into our own solar system, it would swing from within our asteroid ...
