The discovery of water ice around a distant star is allowing scientists to study how the key ingredient for life is delivered to young planets beyond our solar system.

Astronomers have announced the discovery of a new dwarf planet in our solar system, named 2017 OF201. Located far beyond Neptune, it orbits the sun every 25,000 years.

Astronomers have calculated that the gas giant Jupiter used to be twice as big as it is now, based on the odd orbits of two of its many moons.

New research strengthens the case that Venus, long considered a geologically stagnant world, may be more Earth-like in its internal dynamics than once believed.

Scientists looked at Jupiter's massive auroras using the James Webb and Hubble Space Telescopes — and found a mystery they can't fully explain.

NASA's Perseverance rover recently captured a photo of green auroras shining in the Martian sky for the first time. The alien light show, previously assumed to be impossible, could be visible to future astronauts.

By studying seismic waves, researchers have found a layer deep beneath the surface of Mars that could contain enough liquid water to flood the planet with an ocean thousands of feet deep.

Wave-like soil patterns on the Martian surface match those found in Earth's cold, mountain regions, which could help scientists better understand the Red Planet's climate history and search for signs of life.

Researchers have found a candidate for the hypothetical Planet Nine, which could be an undiscovered giant planet way out in our solar system. However, as with all ninth planet research, the new findings were met with some skepticism.
