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 ...

A rocky planet beyond gas dwarfs in LHS 1903 indicates that planetary systems form in unexpected ways.

Astronomers say they have discovered a distant planetary system with planets arranged in a surprising order, challenging long-standing ideas about how planets form. In our Solar System, the four ...

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 ...

The standard model for how galaxies formed in the early universe predicted that the James Webb Space Telescope (JWST) would see dim signals from small, primitive galaxies. But data are not confirming ...

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 ...

(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 ...

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 ...

Astronomers have discovered an extrasolar planet with the largest core of any known planet. The discovery is especially exciting to planet formation theorists, because it provides extremely strong ...
