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.


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.

Decades after archaeologists unearthed King Tut's tomb, we're still talking about the boy-king. This time it's because of his awesome space dagger.

Understanding what's going on in the gaseous comet cloud around HD 181327 will shine a light on the early days of our own solar system.

Understanding just how the "tiger stripes" on Enceladus have sustained water eruptions from its global ocean for so long helps us learn more about Saturn's rings.

The B612 Foundation want to protect Earth from asteroid collisions with a telescope called Sentinel. The foundation just needs a few hundred million dollars to do it.

Reconciling large- and small-scale physics in a new simulation gives us better understanding of our home star.

When the James Webb Space Telescope is in orbit, it will let us peer farther back into the universe’s past than Hubble could have ever imagined.

And you thought it was tough deciding which family to visit during the holidays. We just identified two stars in the process of forming a planet – or a planetary system.

With its huge mirror now assembled, the James Webb Space Telescope is getting closer to being ready. Get to know the telescope that will enable some serious star gazing.

Our moon has the power to influence how much rain we get on Earth. The effect is too tiny to notice, but still: mad respect, Moon.
