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 ...

According to NASA, at least one bright planet can be seen on most nights, depending on the weather.

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

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 around again: Six planets will be visible in the night sky at the same time. This phenomenon, ...

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.

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 ...

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 planets around a nearby star seem to be in the wrong order, hinting that they formed through a different mechanism than the familiar one by which most systems grow ...
