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 ...

LHS 1903 flips rock and gas on their heads, hinting that late-born planets can rewrite the rules around common red dwarfs for now.

Analysis of an ancient meteorite suggests that rocky planets both near and distant from the sun may have formed at the same ...

What can rocky planets orbiting in the outer parts of a solar system teach scientists about planetary formation and evolution? This is what a recent study published in Science hopes to address as a ...

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 ...

Planets orbiting dead stars known as white dwarfs might be able to remain habitable thanks to general relativity subtly altering their motion. When stars like our sun run out of fuel, they expand and ...

Artist’s conception of the K2-360 system, showing the ultra-dense super-Earth K2-360 b (red) in its extremely close orbit around its Sun-like star, with the more distant companion K2-360 c (blue) in ...

The black star represents the position of the star. The colored lines are the orbits of two planets. The yellow one is the outer, and it is highly inclined. The inner one is the red one. As time ...

In our solar system, the four inner planets are rocky and the four outer planets are gaseous. The rocky dwarf planets like Pluto that orbit beyond the gas planets are much smaller than any of the ...
