An artist's impression of white dwarf J1330+6435, which might appear ghostly green because of certain elements in its dense atmosphere

In a First, Astronomers Identify a Star That Might Glow Green. New Research Highlights the Strange Hues White Dwarfs Can Take on

White dwarf stars are too far from Earth to be observed directly. So, scientists reconstructed how they’d look to human eyes based on the wavelengths of light they emit and found a colorful array of objects that might appear yellow, purple or pink

Francis Halzen is a Belgian American physicist who studies neutrinos, sometimes called "ghost particles," which come from space and rarely interact with ordinary matter.

Physicist Wins Nobel Prize for Developing a Massive, Ice-Embedded Observatory That Detects Ghostly Cosmic Particles

Francis Halzen of the University of Wisconsin-Madison led the effort to build the IceCube Neutrino Observatory in Antarctica. His work birthed the field of neutrino astronomy

NASA has been planning and developing the Roman Space Telescope for 16 years.

NASA’s Nancy Grace Roman Space Telescope Launches to Find Exoplanets and Unravel Mysteries of Dark Matter and Dark Energy

The new observatory will complete three surveys of the universe in five years, although it’s designed to function at least twice as long. Its data could change scientists’ basic understanding of the cosmos

Many stars orbit the Milky Way's central supermassive black hole. But S301's orbit, shown in red, is the only one known to be close enough to feel the effects of the black hole's theorized spin.

This Star Orbits Our Galaxy’s Heart at a Record-Breaking Speed—and Could Help Uncover Secrets About the Behemoth Black Hole There

The speedster travels at up to 56 million miles per hour, or about 8 percent the speed of light. It also gets very close to the supermassive black hole at the center of the Milky Way

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

The sugar was detected near the center of our Milky Way galaxy, which shines brightly with stars in this artificially colored image.

In a First, Astronomers Find Sugar in the Space Between Stars, Providing New Clues About the Origins of Life on Earth

Sugars are crucial components of RNA and DNA, the basis of all known organisms alive today. In a new study, the sugar erythrulose was detected in a gas- and dust-filled cloud near the center of our Milky Way galaxy

The new image of the center of the Milky Way, which is packed with stars

See the Most Detailed Photo of the Milky Way’s Heart Ever Taken in Visible Light, Which Will Help Astronomers Hunt for Exoplanets

The European Space Agency’s Euclid telescope was built to study dark matter and dark energy, but for one day last year, it captured the densely packed stars brightening the center of our galaxy

"Night at the Remarkables" 

These Ten Breathtaking Images From the 2026 Milky Way Photographer of the Year Contest Capture the Beauty of Our Galaxy

The gorgeous astrophotographs highlight the dazzling night sky and remind viewers what we risk losing to light pollution

The asteroid Ryugu imaged by the Hayabusa 2 spacecraft in 2018

Life’s Genetic Code Requires Five Key Ingredients. The Asteroid Ryugu Has All of Them, a New Study Suggests

The findings further hint that space rocks may have brought the building blocks of RNA and DNA to Earth long ago

Supernova remnant Cassiopeia A, which sits within the Milky Way

Astrophysicists Found an Abundance of Odd Elements Essential for Life in the Leftovers of an Exploded Star

The surprisingly high amounts of chlorine and potassium in a supernova remnant could help solve the mystery of where these crucial elements come from

An artist's concept of a supermassive black hole shredding a massive star

Astronomers Detect the Brightest and Most Distant Black Hole Flare Ever Seen

The enormous outburst was likely caused by an unfortunate star venturing too close to a supermassive black hole

The glowing red band represents high concentrations of gamma rays across the center of the Milky Way.

Is This Mysterious Glow at the Center of the Milky Way Caused by Dark Matter?

An excess of gamma rays in the center of our galaxy could mean scientists have finally detected dark matter particles—or not

The James Webb Space Telescope, with data from the Atacama Large Millimeter/submillimeter Array, together captured the dusty core of the Butterfly Nebula.

The observations offer an unprecedented look at the center of the nebula, which is shrouded in a band of dust

An artist's depiction of the newly discovered "quadruple system" within the Milky Way. In it, two brown dwarfs orbit each other at the right, and together, they orbit a pair of red dwarf stars at the left.

Astronomers Spot a Rare Quadruple Star System in the Milky Way, Shedding Light on Mysterious Brown Dwarfs

The discovery can help astronomers better understand these little-known objects nicknamed “failed stars”

An illustration of SN2021yfj enveloped in a layer of heavy elements during its supernova explosion

A Unique Supernova ‘Dazzled’ Astronomers and Revealed the Inner Layers of Stars

Researchers observed a supernova in progress that showed the onion-like structure of elements in stars, and the explosion may belong to a class of its own

In this 2012 visualization, the Andromeda galaxy (left) appears in Earth's skies and begins to distort the Milky Way as the two galaxies merge. This hypothetical scenario was previously expected to play out billions of years in the future—now, astronomers say it might not be inevitable.

Our Milky Way Might Not Crash Into the Andromeda Galaxy After All—New Simulations Suggest a 50-50 Chance of Merging

Scientists previously predicted the pair of galaxies would merge in about five billion years. Now, research suggests that outcome is less certain than thought

An artist's rendition of what Eos would look like from Earth if it were visible to the naked eye.

Astronomers Discover a Giant, Glowing Molecular Cloud Hidden in Earth’s Cosmic Neighborhood

The cloud, named Eos after the Greek goddess of dawn, had eluded researchers because it contains very little carbon monoxide

An artist's illustration portrays the supermassive black hole at the center of the Milky Way, known as Sagittarius A*.

James Webb Telescope Reveals a Dazzling Light Show From the Milky Way’s Black Hole

Unpredictable bursts of light are pulsing from the debris surrounding Sagittarius A*, offering new insights into the mysterious behavior of the most massive object in our galaxy
