The Lyrids are slated to peak on April 21-22, though the moon will be nearly full, which could make the meteors more difficult to see.

How to Watch the Brilliant Lyrid Meteor Shower This Month

Fiery streaks will illuminate the night sky from April 15-29, with the spectacle's peak occurring from April 21-22

Tens of millions of people watched Monday's total solar eclipse.

When Are the Next Solar Eclipses? 2026 Promises Totality in Europe, While Much of America Has a Decades-Long Wait

The next total solar eclipse visible from the contiguous U.S. won’t take place until August 23, 2044—but eclipse chasers will have other opportunities to experience totality before that

A slice of the largest 3D map of the universe ever made, depicting 600,000 galaxies across the cosmos—less than 0.1 percent of the map's total. Earth is at the tip in the lower center, and the most distant galaxies represented are 11 billion light-years away.

Dark Energy Could Be Evolving Over Time, Raising Questions About the Nature of the Cosmos

The largest 3D map of the universe ever made hints that dark energy might not be a constant, though the findings must be backed up with more data

Furnished with permission from the British to cross into their waters, Samuel Williams set sail for Penobscot Bay in south-central Maine, which he thought was within a solar eclipse's path of totality.

Why Scientists Are Calling for the Moon to Be Better Protected From Development

Only a few lunar sites are ideal for certain cutting-edge research—and they’re under threat from mining, satellites and bases, scientists argue

The darker areas across Titan's equatorial regions represent its dunes, as taken by the Cassini rover.

Titan's Massive Dunes May Be a Comet and Moon Graveyard From the Early Solar System

A new modeling study suggests the dark dunes on Saturn's largest moon are made of tiny particles created by crashing comets and moonlets billions of years ago

Officials have been working toward the designation for four years.

How Ancient Civilizations Reacted to Eclipses

Communities may have thought the celestial events were messages from the gods, a reason to abandon a settlement or a cue to end a war

The Whirlpool Galaxy (also known as M51), located 31 million light-years from Earth, is a particularly radiant object seen during the Messier marathon. This image was captured by the Hubble Space Telescope—skywatchers looking through a backyard telescope or binoculars would see the galaxy in far less detail.

What It Takes to Complete the Ultimate Skywatching Endurance Challenge

The "Messier marathon" prompts space hobbyists to spot 110 celestial objects in one night, and the best time to try it is in March
