ASTRONOMY

Usually it's all about the Perseids, but this summer, the Delta Aquariids is the meteor shower to catch, thanks to July's "old moon." Here's how to view it.

The bright green light that streaked across skies over Massachusetts, Rhode Island, and Connecticut the night of July 24 was likely a fireball meteor, experts say.

The half-blood thunder moon—a partial lunar eclipse that coincides with a full moon in July—falls on the 50th anniversary of the Apollo 11 launch.

Saturn reached opposition this month, which means now is the ideal time to see the second-largest planet in our solar system from your backyard.

The icy rock planet in the Kuiper Belt has gone 12 years without a name, but now people can cast a vote to give it an official identity. Just not Boaty McBoatface.

The moment astronomy and sci-fi lovers have long awaited is finally here. That's an actual black hole you're looking at.

Capturing an image of the distant, supermassive black hole in the center of our galaxy has been compared to “standing in New York and counting the individual dimples on a golf ball in Los Angeles."

A full pink moon isn't actually pink—but it's so important that it helps determine when Easter will occur each year.

Galileo Galilei, the father of modern astronomy, probably never dropped anything off the leaning tower of Pisa, and he didn't actually invent the telescope. But he did change history with his discoveries about the cosmos.

The next supermoon will light up skies on Tuesday, February 19. This one will be a snow moon, a full moon that comes only at this time of year.

In 2004, the rover Opportunity landed on Mars. Originally intended to serve a mere 90-day mission, the rover instead beamed back scientific discoveries for more than a decade—and now its groundbreaking mission is over.

Astronomical distances are very specific, but estimating lights years without a calculator isn't impossible (even if there are dozens of zeros involved).
