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

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 ...

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

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 ...

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 ...

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 ...

Planets are often described as ancient, unchanging worlds. Planets are born out of chaos, shaped by violent collisions and swirling dust. They grow, they evolve, and in their own way, they age. Some ...

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 ...
