When it comes to explaining how planets are formed, the protoplanetary hypothesis is the most widely accepted explanation. In simple terms, the donut-shaped disc of dust and gas around a star forms ...

A recent study published in Science examines exoplanet LHS 3154b that orbits its parent star in just 3.7 days but is 13.2 times as massive as the Earth with the star being nine times less than our Sun ...

(CNN) — Astronomers are questioning the theories of planet formation after discovering an exoplanet that technically shouldn’t exist. The planet, about the mass of Neptune and more than 13 times as ...

The astro-modified camera used to take this photo lets in the hydrogen alpha light that is normally filtered out. This modification makes the camera more sensitive to the red end of the ...

LHS 1903 is a small red M-dwarf star that is cooler and shines less brightly than our Sun. Scientists used telescopes in space and on Earth to discover four planets orbiting LHS 1903. With those ...

We already know a decent amount about how planets form, but moon formation is another process entirely, and one we're not as familiar with. Scientists think they understand how the most important moon ...

Astronomers have uncovered the most promising evidence yet for the existence of dark stars—giant cosmic objects powered by dark matter, rather than the fusion processes typically seen in stars. These ...

A pair of NASA spacecraft detected tiny variations in the Moon's gravitational pull, which may be the result of a dense layer sinking to the bottom. Reading time 2 minutes During its early years of ...
