Will there be a new meteor shower on the night of May 30–31? There's only one way to find out.

Astronomers think they might have a solution to the conundrum of the Sun's chemical composition.

Unlike most asterisms, many of the Big Dipper's stars really are physically connected. They belong to a loosely bound stellar stream called the Ursa Major Moving Cluster.

A piano concerto based on the solar system’s planets just had its world premiere. And you can hear a sampling of the music right here!

The Sun is ramping up activity, but contrary to some reports, this solar cycle is still consistent with scientists' predictions.

The advancing spring sends Vega high and Capella low. The Coma Berenices cluster glitters shyly way up, big and dim. Glance up anytime to check on changing Beta Lyrae. And now in the dawn, Jupiter aligns with Mars.

Astronomers are exploring a celestial particle accelerator in the Eel Nebula that surrounds a distant pulsar.

NASA’s Mars Insight lander witnessed the largest quake detected on another world at just the right time — as the lander begins to run low on power.

Astronomers connect the dots between two strange doppelganger galaxies, uncovering what might be a string of galactic pearls created in a cosmic collision 8 billion years ago.

Using a worldwide array of telescopes, the Event Horizon Telescope team has given us our first look at Sagittarius A*.

Astronomers have spotted the X-ray flash that precedes a nova. The brief flare is the first sign of a white dwarf erupting into a nuclear-fusion fireball.

Using Earth as an example, astronomers are testing a new technique that could image rocky exoplanets without resolving them.

Two Sky & Telescope authors have won prestigious awards recognizing excellence in science journalism.

North American skywatchers can see the Moon turn a reddish hue as it flirts with Earth’s shadow on the night of May 15–16.

The full Flower Moon ducks inside Earth's shadow in a total lunar eclipse this month. We help you prepare for all the highlights of the special event.

The Moon aligns with Pollux and Castor – but how precisely for you? Three zero-magnitude stars form a far-flung spring triad. And with Libra and Bootes up, the two oldest things you will ever see await your binoculars or scope.

What’s the mechanism behind millisecond-duration bursts of radio energy coming from outer space? A team searched for visible-light counterparts to constrain the origin of fast radio bursts — and found one.

Many an amateur astronomer has desired a bigger telescope, but sometimes it's worth taking a moment to appreciate what we have.

Plakha Alexander — amateur astronomer, owner of Astro-Gadget.net, and Ukrainian — shares his experiences since Russia's invasion began.
