Astronomers Peered at the Early Universe and May Have Discovered a New Kind of Celestial Object: Black Hole Stars

Since the James Webb Space Telescope started collecting data in 2022, it has found puzzling objects dubbed little red dots. A new study suggests they might be giant black holes with some characteristics of stars

Streaks of light from Venus and satellites

An Aerospace Startup Just Got Approval to Test Beaming Sunlight to Earth. Here’s Why Experts Are Worried—and Petitioning

By 2035, Reflect Orbital aims to launch up to 50,000 satellites equipped with mirrors to provide sunlight to Earth-based solar panels. Critics are concerned about impacts on wildlife, astronomy research and human health

Totality reveals the solar corona over San Millán de los Caballeros, Spain.

See Magnificent Photos of the Total Solar Eclipse Over Europe That Showcase the Sun’s Beauty and the Wonder of Skywatching

The moon’s shadow swept over Earth on Wednesday, captivating millions across the planet. It was the first total solar eclipse since the North American eclipse of April 2024

The highest-resolution image of the sun's surface ever captured

Stunning New Images Reveal Whirlpools on the Sun’s Surface. The Swirling Structures Might Help Power Solar Flares

Observed directly in the solar photosphere for the first time, the vortices might braid magnetic fields, thought to be responsible for energy buildups and eventual outbursts. The features also offer clues about why the sun’s outer atmosphere is millions of degrees hotter than its surface

The total solar eclipse on August 12, 2026, will be the first time totality has occurred on Earth in 28 months.

How to Watch the Total Solar Eclipse on a Livestream, Witnessing the Rare View of the Sun’s Corona From Your Own Home

Wednesday’s eclipse will bring dark skies to parts of Russia, Greenland, Iceland, Portugal and Spain. But with these online broadcasts, you can view the spectacle from anywhere

The Perseid Meteor Shower Peaks This Week Amid Ideal Viewing Conditions. Here’s How to Watch the Event’s Bright Shooting Stars

The much-anticipated annual event peaks on the night of August 12 into the next morning. This year, the moon won’t crash the party, as our natural satellite will be in its dark new moon phase

The crew of the Artemis 2 mission captured this image of a total solar eclipse just after rounding the far side of the moon on April 6.

‘Like a Hole in the Universe’: Artemis 2 Astronaut Victor Glover Reflects on Seeing a Total Solar Eclipse While Flying by the Moon

The four astronauts who rounded Earth’s natural satellite in April got an extremely rare view of the dark lunar disk blocking out the sun. Researchers say the observations provide unique scientific value for understanding our star’s mysteries

The Falcon 9 rocket's upper stage left its mark on the moon's surface. 

A SpaceX Rocket Part Just Slammed Into the Moon, Creating a Dust Plume and Crater. Here’s What Some Scientific Instruments Saw

The Korea Aerospace Research Institute captured before-and-after images of the impact site, and a telescope in Chile detected signs of the plume. However, no one was able to watch the collision live

Neptune May Have Once Witnessed a Lunar Massacre That Turned Its Original Moons ‘Inside Out’

A new study identifies an unexpected mineral in two of the planet’s inner moons, pointing to a destructive past in which a large object got pulled into the system and obliterated the former, larger satellites

An artistic rendering of a tidal disruption event, when a black hole rips apart and devours a star that got too close. These events help scientists find black holes, which don't emit light.

In a First, Astronomers May Have Spotted a Supermassive Black Hole That Wandered to the Edge of Its Galaxy

These giant celestial objects have mostly been identified at the centers of galaxies, where they’re known to reside. But a recently discovered one—found because of the light emitted while it snacked on a star—appears to be more than 30,000 light-years from its host galaxy’s heart

Betelgeuse, the inset image in the middle, is located in the constellation Orion, on the right. New images hint at a small companion star, shown in the inset image on the left, orbiting the supergiant star.

New Images Provide the Best Evidence Yet That Supergiant Star Betelgeuse Does, Indeed, Have a Long-Theorized Stellar Companion

The research team is mostly convinced by the data, but they want to capture additional observations in 2027 to confirm what they’ve found

Is This Giant Celestial Body a Moon, a Planet or Something in Between? The Strange Object Calls Astronomical Labels Into Question

The newly found object, estimated to be roughly as massive as Jupiter, orbits a brown dwarf—a “failed star”—which in turn circles a small star. For now, researchers are calling the puzzling body an “exosatellite”

The upper stage of a SpaceX Falcon 9 rocket is estimated to hit the moon on August 5.

A SpaceX Rocket Part Is Expected to Smack Into the Moon in August, Highlighting the Growing Problem of Space Junk

The unintended event also creates an opportunity for scientists and skywatchers to witness lunar impact dynamics in real time, although the debris will hit a sunlit portion of the moon from the perspective of Earth, making it hard to see

Could Life Exist on This Nearby World? In a First, Astronomers Find an Atmosphere on an Earth-Like Exoplanet in the Habitable Zone

While the celestial body seems to host three features that could make a livable environment—an atmosphere, a rocky composition and a temperature that could allow liquid water to sit on the surface—researchers have not currently detected any residents

An amateur astronomer thought he found an impact crater on Google Maps. Then, an expedition to the site confirmed that he was right.

Cool Finds

An Amateur Astronomer Using Google Maps Spotted a Strange Indentation. It Turned Out to Be a Meteorite Crater From 390 Million Years Ago

Scientists confirmed the astronomer’s suspicions with an expedition to the site in Quebec. The discovery offers a rare case of a reported new crater turning out to be real
