There are a couple of ways that scientists can date planets, so which planets formed first in our solar system?

Warm Jupiters are rewriting the rules of planet formation - showing eccentric orbits that stay strangely aligned with their ...

One of the most notable properties of the giant planets in our solar system—Jupiter, Saturn, Uranus and Neptune—are the ...

Astronomers observe for the first time the actual motion of spirals in a protoplanetary disk, revealing gravitational ...

The methane gas may constitute a rarefied atmosphere, or it may come from erupting plumes on Makemake’s surface.

Rogue planets may be more common than we thought, and they may form alone in the void in the same way stars do, suggests a recent study. We think we know how the universe is structured: Moons orbit ...

ESO's Very Large Telescope has observed a rogue planet and revealed that it is eating up gas and dust from its surroundings at a rate of 6 billion tons a second.

"It shows that Makemake is not an inactive remnant of the outer solar system, but a dynamic body where methane ice is still ...

Planets may begin forming much earlier than scientists once believed during the final stages of a star s birth, not afterward. This bold new model, backed by simulations from researchers at SwRI, ...

Scientists suggest that dry ice on Mars may move and burrow beneath the surface, creating patterns similar to sandworms from Dune and shedding light on the planet’s changing landscape.
