WASHINGTON – Astronomers have observed a planetary system that challenges current planet formation theories, with a rocky planet that formed beyond the orbits of its gaseous neighbors, possibly after ...

Astronomers have found a unique planetary system orbiting a red dwarf star. The system includes a rocky planet situated beyond its gaseous siblings, contradicting existing planet formation theories.

Astronomers have uncovered a distant planetary system that flips a long-standing rule of planet formation on its head. Around the small red dwarf star LHS 1903, scientists expected to find rocky ...

A closer look at the planets around a star called LHS 1903 may just flip our understanding of how planetary systems form.

Typically, from what astronomers have gathered thus far, star systems follow a tidy logic: small, rocky worlds huddle close to the warmth of their star, while massive gas giants bloat up in the colder ...

A team of astronomers led by the Flatiron Institute’s Kishalay De discovered that a star in the Andromeda Galaxy disappeared without going supernova, and instead collapsed directly into a black hole.

Astronomers have found thousands of exoplanets around single stars, but few around binary stars—even though both types of stars are equally common. Physicists can now explain the dearth.

Astronomers suspect that a massive metallic cloud swirling in a nearby star system could be hiding a giant planet or dwarf star from view, after it drastically dimmed a sun-like star for around nine ...

Earth may owe some of its properties to a nearby star that blew up just as the solar system was forming. This pattern, which saw a supernova bubble envelop the sun and shower it with cosmic rays, may ...
