Distant galaxies in Webb images suggest we need to rethink star and galaxy evolution in the early universe.

A chance alignment between Earth and a Mars-bound spacecraft has given us a rare glimpse at the motions of high-energy particles from the Sun.

Don't use a full Moon pass to skip this year's Perseid meteor shower. Right here, right now, we're going to help you make the most of it.

South Korea's lunar orbiter has launched successfully for the Moon, joining a growing number of missions there.

The Moon and Saturn come to opposition this week, showing us their full sunlit faces. Jupiter looms big late in the night, Vega attains the zenith, and we cross the midpoint of summer. The Perseid meteors get partly mooned out.

Even though it's far past its warranty, Hubble is still proving its worth in this new era that includes the James Webb Space Telescope.

Long, hot days mean sleepless nights for stargazers, but it's worth it for the magic that happens under a dark, cool sky.

Why does the biggest planet in the solar system have such flimsy rings? New research shows Jupiter's moons may be to blame.

August marks the return of the Perseid meteor shower — and as you’re looking out for shooting stars while listening to this month's Sky Tour podcast, look for Saturn low in the southeast as soon as night begins to fall.

New imagery from the James Webb Space Telescope shows a nearby galaxy in a whole new light.

As the Big Dipper dips and the Guardians of the Pole align one over the other, Saturn looms low in the southeast and the False Comet teases at its highest.

A pulsar has devoured enough of its stellar companion to grab the title for most massive known neutron star.

The ecliptic, simply put, is the plane of Earth’s orbit around the Sun. It extends beyond that to include the seven other planets.

Something we take for granted about the crescent Moon's appearance may be nothing more than an optical illusion.

What kind of planets are likely to ensnare comets coming in from the icy outer reaches of a planetary system?

Blazars, the gas-guzzling black holes at the center of galaxies, could make most of the tiny particles known as neutrinos we catch on Earth.

Scientists have observed pulses from a fast radio burst, suggesting the flash might have come from a neutron star.

Astronomers have found a dormant black hole orbiting a massive blue star in the Large Magellanic Cloud, a satellite galaxy of the Milky Way.

It's tiny. It's challenging. But you won't get the chance to see Iapetus transit the globe of Saturn again until 2037!

The waning Moon says hi to late-night Saturn, the Teapot starts tilting, the Great Square thrusts up, and the Milky Way arches high.
