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 ...

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

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

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 ...

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 ...

About 4.6 billion years ago, a celestial cloud collapsed, paving the way for our solar system to form. Then, a nebula with strong gravitational pull took shape, kick-starting the birth of the sun. But ...

Since the 1990s, scientists have discovered approximately 6,100 planets outside our solar system, called exoplanets.

what if a planet did not need a star at all? This is the provocative question at the heart of an emerging astronomical debate, wherein the discovery of rogue planets-worlds free-floating in the galaxy ...

The host star, TOI-6894, is a red dwarf with only 20% the mass of the Sun, typical of the most common stars in our galaxy. Until now, such low-mass stars were not thought capable of forming or ...

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 ...
