Astronomy

Astronomy is a broad discipline covering all facets of astrophysics. In this section you can learn about the origins of the universe, black holes and other astronomical phenomena.


We might be only a few years away from seeing whether potentially habitable worlds are inhabited. How cool is that?

And solving that issue could go a long way toward making our planetary neighbor habitable.

Energized subatomic particles bombarding Earth from outer space can cause the electronics inside laptops, cell phones and other devices to crash.

Say hello to the newly discovered TRAPPIST-1 system, which is just 39 light-years away and filled with seven Earth-like planets.

Scientists have a new idea, and it has to do with gravitational attraction and repulsion.

A total solar eclipse and a comet flyby are on the list of fascinating astronomical happenings 2017 has in store.

Satellites have found evidence of massive underground channels formed by molten rock on the moon. They could be stable enough to house lunar pioneers, a study suggests.

It's a bird, it's a plane, it's supermoon! Aside from being bigger and brighter than a regular moon, does a supermoon affect anything on Earth?

Saturn's largest moon Titan is the only other celestial body we know of that has liquid lakes on its surface. NASA has just captured some amazing footage of clouds.

The rings of Saturn, Uranus and Neptune may be remnants of smaller planets destroyed long ago by the gas giants' powerful gravity.

How could Phobos withstand the impact that created such a large crater without simply shattering into pieces? A new mathematical investigation answers that question.

The European Space Agency's Gaia satellite observatory has created a 3-D model of the Milky Way — and beyond! — that charts more than a billion stars.

NASA scientists say solar eruptions could have played a role in creating not only friendly environments, but also the building blocks of life itself.

The sun's atmosphere is actually hotter than its surface, even though you'd assume the surface is what generates all that heat. How does that work?

NASA's solar-observation satellite IRIS spotted an instance of this powerful natural electromagnetic phenomenon, and caught it on video.

Radiation from distant galaxies and even black holes travels light years through the universe to have a tiny but measurable impact on humanity.

And if we're going to get technical about it, neither do those of us here on Earth.

A NASA spacecraft captured footage of a comet hurtling toward the sun. And then it got crazy

Heading to the moon? You might want to ask the FAA first.

The Japanese satellite aimed to look deep into the universe. It died just a month after launch—but provided a brief, tantalizing hint of discoveries it might have made.

After a five-year trip, the space probe reaches its destination on a mission to learn about the gas giant's origin and evolution.

The space telescope's ultraviolet observations come days before the Juno space probe will arrive to orbit the gas giant's polar regions.

Could a new space and aeronautics partnership between NASA and the United Arab Emirates Space Agency make Mars a reality within our lifetime?

This is the largest-ever planet found in orbit around a binary star system, and like our own solar system neighbor, is a gas giant that probably has moons.

The LISA Pathfinder prototype just pulled off a technological breakthrough on the path to the ESA's 2034 mission to observe Einstein's ripples in space-time.
