Planetary systems in the Milky Way galaxy tend to follow a particular pattern: rocky planets toward the center, closest to ...

The stars may not align, but the planets will. Stargazers are in for a treat later this month when six planets form a line during a rare event scientists are dubbing a “planetary parade.” The ...

An international team of astronomers has discovered a distant planetary system that challenges long-standing theories of how planets form. Across our galaxy, astronomers routinely observe a ...

A rocky exoplanet in the LHS 1903 system defies planet formation models, hinting that gravitational upheaval reshaped the red dwarf’s four worlds.

The discovery overturns traditional models that predicted gas giants in outer orbits and suggests planets can form in gas-poor environments.

Mark your calendars for the last week of February, because one of the coolest celestial events is coming up where six planets will be visible in the night sky at the same time. This phenomenon, known ...

In “Citizen Science in Astronomy (Part 7),” SETI Institute astronomers Dr. Franck Marchis and Dr. Lauren Sgro highlight two rare and compelling discoveries and the crucial role of citizen scientists ...

Astronomers say a newly discovered solar system about 116 light years from Earth is challenging long held ideas about how planets form.According to CNN, researchers using telescopes from NASA ...

Astronomers are actively searching for Earth-like planets, with thousands of exoplanets now confirmed. While Proxima Centauri ...

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 new study has proposed the existence of Planet Y, an alternative Planet Nine candidate that is smaller and closer to Earth than the hypothetical Planet X, which astronomers have been hunting for ...
