Here is a gallery of awesome photos of the ‘Great American Solar Eclipse’ taken by astronauts, satellites and stratospheric balloons!

There are many unknowns regarding the potentially habitable exoplanet Kepler-186f, but it may have similar light (from its star) and gravity as Earth.

Living on comets requires great care — the gravity is so weak that you could easily jump off the frozen bodies and into space.

Much is unknown about Pluto, including what its surface features are like and what kind of weather patterns it has, if any.

Neptune's moon Triton has some unique properties among the moons of the solar system, which could make it an interesting location for a space colony.

Titania and Miranda offer up great views and places to explore, but both of the moons suffer from extreme cold and very low gravity.

Titan is one of the most habitable places for humans in the solar system, while Enceladus is one of the best places to look for life.

Jupiter's moon Europa suffers from extreme cold and deadly radiation, but its astronomical and geological sights are unique in the solar system.

Low temperatures, gravity and sunlight would define the experience of living on Ceres, the largest asteroid belt object.

Life on Mars would be full of chilly weather, large dust storms and geological sights dwarfing anything on Earth.

With its very low gravity, interesting topographical features and great view of Earth, the moon could be an exciting place to live.

With its intense heat, thick air and high pressure, Venus is not an ideal vacation spot.

Have you ever wondered what it would be like to live on Mercury. So did we. Mercury's gravity, temperatures and weather are all very different from Earth's. Here's how.

The two different classes of jet-spewing active galaxies called blazars may, in fact, be a single hybrid type that evolves over time, according to new research.

Material blasted off Mars from meteor impacts may have scarred the surface of Phobos, one of the Red Planet's two tiny moons, a new study suggests.

Microorganisms from Earth could hitch a ride on spacecraft and end up colonizing the Red Planet and other celestial bodies in the solar system, recent research suggests.

Four spacecraft and one ground-based observatory recorded the eruption of a powerful X-class solar flare on March 29, making it the best-observed such event in history, NASA officials said.

Like ancient seafarers, the insects rely on the starry sky and galaxy glow to move away back from a poop pile.

NASA is planning to use harpoons to collect samples from comets, which may help scientists learn more about the origin of life on Earth.

NASA says that there is little danger from radiation from the launch.

Everything you need to know about the new Mars mission and rover.

A trio of astrophsyicists recently won the Nobel Prize in Physics for their 1998 discovery of dark energy.
