The unexpected arrangement of exoplanets around a star more than 100 light-years from Earth might change how we think about planet formation.

Three of the five naked-eye planets emerge in the fading afterglow of sunset. The first-quarter Moon Tuesday passes as close to straight up as you may ever see it. And can you try for Sirius B?

Space debris are contaminating our atmosphere at very high altitudes – and we don't yet understand the effects.

The RAMSES mission to the asteroid Apophis will launch in 2028 to meet the asteroid before its close encounter with Earth.

Traversing the galaxy from places yet known, a few interstellar objects have taken a quick dip into our solar system. Astronomers look to nearby planet-forming stellar systems as possible launching posts.

Master the basics of the most popular astronomical image-processing software.

Here's how you can contribute to the science of astronomy.

After a recent explosive outburst, Comet 29P/Schwassmann-Wachmann is bright enough to see in a medium-sized telescope.

On February 18th, the willowy crescent has a close shave with Mercury, so close that it occults the planet from some U.S. cities.

Three planets await in the western twilight, though low Venus is a toughie. The crescent Moon passes them and, for the lucky, occults Mercury. After dark, Dog and Hare accompany Orion. And try for Kemble's Cascade.

Astronomers might have spotted a star in the Andromeda Galaxy collapsing directly into a black hole, without the accompanying fanfare of a supernova.

Astrophotography with remotely operated telescopes is easier than you might think.

Here's a different approach to recording deep-sky targets over natural and urban landscapes.

Dedicating multiple nights to a single target can lead to surprising results.

Here's how to reveal the reflected light of stellar explosions photographically.

Here's how you can add a personal element to your solar eclipse photography.

Astronomers might have found a moon half the mass of Jupiter orbiting in a nearby system, based on the wobbles of its host world.

Upgrading to the latest cameras may require changing your imaging techniques.

The 4-billion-year-old Moon rocks brought back from the farside of the Moon challenge ideas about what it was like in the early solar system.

Astronomers have discovered three still-growing galaxy clusters in the early universe that point to a faster track of evolution than expected.

The Winter Hexagon encompasses the brightest winter stars. Near Orion, the Big Dog prances and the Hare crouches. And the moonless dark this week opens telescopic deep-sky depths.
