NASA detected a faint "heartbeat" signal from Voyager 2, after an erroneous command caused the spacecraft to lose contact with Earth.

Many skywatchers look forward to seeing the Perseid meteors every August, and this month’s Sky Tour episode why they’ll be especially good this year. You’ll also learn what's so special about the full Moon that falls on the night of August 30–31.

Images capture the birth of stars and planets in multiple results from space- and ground-based telescopes.

Find some of our favorite resources for the April 8, 2024, solar eclipse, including apps, video explainers, children's activities, and books.

Venus turns super-interesting and then disappears. Mercury lingers behind it in twilight. So does little Mars in third place. On the other side of the sky, the Moon passes Saturn.

Stargazers will be interested not only in the annular eclipse this October but also in the dark skies in parks along the eclipse path!

With Venus approaching inferior conjunction in August here's a foolproof way to follow its thinning crescent as the planet transitions from Evening Star to Morning Star.

The white dwarf J2033 seems to switch rapidly between two compositions.

A galaxy 600 million light-years away appears to be trailing gas in a string 1.2 million light-years long, but explaining its origins presents a challenge.

Comet Pons-Brooks, a dim comet on its way to a great apparition next spring, suddenly sprang into action overnight, brightening by five magnitudes. Now you can see it in a 4-inch telescope.

Dust is usually the product of generations of star formation. So what is all this dust doing in the early universe, just a few hundred million years after the Big Bang?

Low in twilight, Mercury consorts with Venus and squeaks by Regulus. The waxing gibbous Moon does what it does every July: crosses Scorpius and Sagittarius.

Astronomers have spotted the first solid evidence for a planetary Trojan body forming in another system outside our own.

An unidentified source has been beaming out a pulse of radio waves every 22 minutes since 1988.

Three distant galaxies imaged by the James Webb Space Telescope might actually be "dark stars" powered by dark matter annihilation, claims a team of astronomers.

Venus, Mercury, and Mars, very unequal, gather low in the western twilight with the crescent Moon stepping over them and Regulus in their midst. And do you know which way the Kite of Boötes bends?

New research proposes a way for fast radio bursts to escape the confines of a magnetized star and jet out into space — by getting help from theoretical particles called axions.

NASA's Perseverance has sniffed 10 rock samples and found signatures of organic molecules, a sign of a complex geochemical past.

Deep-sky objects may appear static throughout our lifetime but by carefully "blinking" archival and current images we can discern real changes in their appearance.

Satellites’ leakage radiation, now detected for the first time, may become a major problem for radio astronomy, as “megaconstellations” keep on growing.
