These NEAs are part of an elusive population that lurks inside the orbits of Earth and Venus. One of the asteroids is the largest object.

A new citizen science project allows volunteers to play an important role in helping scientists learn more about the atmosphere on Jupiter.

Scientists use modern rocks, moon samples and meteorites to figure out when and how the Earth and moon formed and what they had looked like.

The surface of the moon and rocky planets, Mars in particular, are of huge interest to anyone trying to explore our solar system.

The star system consists of a binary set of stars – two stars that orbit one another and then one, more massive star orbiting the binary.

MIT astronomers have discovered two terrestrial, Earth-sized, planets that lie just 10 parsecs, or about 33 light-years, from Earth.

Samples returned from the Hayabusa2 mission provides invaluable insights into the formation and evolution of our solar system.

Researchers at MSU, China and France have unveiled a new theory that could help solve a galactic mystery of how our solar system evolved.

NASA's priority should be the Enceladus Orbilander - a mission to search for evidence of life on Enceladus, Saturn's sixth-largest moon.

Ice volcanoes emit a "thicker, slushy mix of ice and water, or perhaps a solid flow like glaciers" rather than lava.

Researchers have discovered a new form of ice, redefining the properties of water and our understanding of distant, water-rich planets.

A team of space scientists has published a paper suggesting that there may be an Earth or Mars-sized planet orbiting beyond Neptune.

Astronomers spying on a stellar system located dozens of lightyears from Earth have, for the first time, observed a troubling fireworks show

Thousands of alien worlds are known to orbit stars beyond our solar system. And many more worlds, possibly harboring life.

Studying the atmospheres of white dwarfs that have been “polluted” by such debris, researchers have identified exotic rock types.

Dozens of space-based telescopes operate near Earth and provide incredible images of the universe. Imagine a telescope in the outer system.

Mars is a potential source of what is sure to be one of the most valuable elements in the space economy—hydrogen.

Researchers from Chile directly measure the amount of both water and carbon monoxide in the atmosphere of a planet in another solar system.

One of the youngest planets ever found around a distant infant star has been discovered by an international team of scientists.
