Far beyond Neptune, in the frozen depths of the Kuiper Belt, many ancient objects oddly resemble giant snowmen made of ice and rock. For years, scientists wondered how these delicate two-lobed shapes ...

Our solar system is a weird place. Much more than a home to eight planets, it’s filled with a myriad of fascinating other smaller bodies, including moons, asteroids, and comets. In recent decades, ...

A group of astronomers has found a solar system 116 light-years from Earth that seems to challenge current theories about how ...

Researchers have been focusing on the study of our solar system for centuries, looking at the physics, dynamics, as well as the composition of solar system bodies. Our solar system – which includes ...

Astronomers have found a compact solar system whose planets line up in a way that, according to current models, should not be possible. Around the small star LHS 1903, a dense rocky world orbits on ...

CAPE CANAVERAL, Fla. — Astronomers have discovered a rare in-sync solar system with six planets moving like a grand cosmic orchestra, untouched by outside forces since their birth billions of years ...

Scientists have long believed that comets and a type of very primitive meteorite called carbonaceous chondrites were the sources of early Earth’s volatile elements — which include hydrogen, nitrogen, ...

An exoplanetary system about 116 light-years from Earth could flip the script on how planets form, according to researchers who discovered it using telescopes from NASA and the European Space Agency, ...

Estimating ages of specific events is one of the most difficult problems in astrophysics. While we have a precise (and probably accurate) age for the solar system, we do not have precise ages for each ...
