Space
Come along with us as we explore outer space, including everything from NASA to astronomy to aliens.
The silvery moon turns blood red in this stunning time lapse.
The “super” blue-moon will turn blood red before dawn. NASA’s got it covered with a live stream.
Total lunar eclipses, explained.
An 8-minute history of the giant field of physics.
Tonight’s shooting stars will be spectacular.
A slightly larger, brighter full moon will appear in the sky Sunday night.
You can find them rising in the eastern sky overnight.
This tantalizing finding raises more questions than it answers.
1.4 times the mass of our sun — why “Chandrasekhar’s limit” is essential for understanding why some stars form black holes.
LIGO kick-started an astronomical treasure hunt that ended with colliding neutron stars and gold.
Two neutron stars collided 130 million light-years away. Thanks to LIGO, scientists were able to witness it.
The 2017 Nobel Prize in physics goes to the discovery of these distortions in spacetime.
Cassini may be gone, but these gorgeous Saturn photos are ours forever.
For 13 years, Cassini explored the gas giant and its moons. On Friday, it ended its mission in an elegant dive.
Scientists are bracing for the destruction of the beloved spacecraft. Here’s how to watch the emotional moment.
Darkness, 500-plus miles above Earth.
Everything you need to know about the August 21 eclipse.
There will be a total solar eclipse January 27, 2837. Here’s how we know.
NASA produced these extremely accurate maps of the 2017 solar eclipse.
“You suddenly feel as though you can see the clockwork of the solar system.”
Great spot! Juno sends back incredible images of Jupiter’s iconic storm.
A small step toward more affordable spaceflight.
The Harvard physicist on Galileo, Neil Gorsuch, and checking email.
LIGO just found gravitational waves ... again. The real excitement is what happens next.
Damn, Jupiter looks sexy.
A closer look at Saturn’s atmosphere.
The spacecraft survived its first “grand finale” dive. These pictures prove it.
The spacecraft begins its “grand finale” before crashing into the gas giant later this year.
NASA found compelling evidence that Enceladus, Saturn’s icy moon, contains the right chemicals to support life.
The gas giant is like a mini solar system inside our own. At opposition, it shines extra bright.
Every image you’ve seen of a black hole is an illustration. A giant “virtual” telescope may change that.
Before it crashes, Cassini may solve one of the greatest mysteries of Saturn’s rings.
What exactly makes a journey to Mars so perilous?
This tiny star has 7 planets that potentially could be suitable for life.
It’s not aliens. It’s never aliens.
What the constellation looks like in the darkest of places versus in cities.
Here’s how to watch.
Astronomers captured this 7-year time lapse of planets orbiting a faraway star.
…without killing each other.
