Previously, scientists believed that the majority of Earth's volatiles came from asteroids that formed closer to the Earth. The findings provide important insights into how Earth came to have the unique conditions required for life to thrive.
Researchers using MeerKAT have found nine millisecond pulsars, the majority of them in uncommon and occasionally unusual binary systems.
Two planets with Earth-like masses have been found in orbit around the red dwarf star GJ 1002, which is close to our solar system, by an international team of scientists led by IAC researchers.
The tiny galaxy HIPASS J1131-31 has been dubbed the Peekaboo Galaxy because it emerged in the last 50-100 years from behind a fast-moving star that was obscuring astronomers' ability to detect it
Newborn class 0 Protostars feed at a furious rate and grow through surprisingly frequent feeding frenzies, a recent analysis of data from the Spitzer Space Telescope shows
The interior of Planum Boreum, Martian north polar cap, can now be seen in much greater detail thanks to a newly enhanced 3D radar image. The 3D radargram image was produced using data from NASA's Mars Reconnaissance Orbiter's Shallow Radar (SHARAD) instrument.
Astrophysicists have proposed a method for observing Leo 1* - which could be the second-closest supermassive black hole to Earth, 3 million times the mass of the Sun hosted by the dwarf galaxy Leo I.
A blazar like blazar Markarian 501 is bright because one of its strong jets of fast particles is directed directly at Earth. How the particles in these jets become accelerated to such high energies has long been a mystery to scientists.
