The new study examined Mars' gravitational field to infer its interior structure.

Mars’ Southern Half Is Weirdly Warm Underground. The ‘Thermal Anomaly’ Might Explain Why the Planet’s Hemispheres Look So Different

Researchers used a novel technique to figure out what’s going on inside the Red Planet. The work suggests that the interior of the southern hemisphere is hundreds of degrees hotter than that of the northern hemisphere and partially molten

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

The deep partial lunar eclipse will peak on August 28 at 12:13 a.m. Eastern time.

Turn Your Eyes to the Night Skies This Week to See a Near-Total Lunar Eclipse. It’ll Temporarily Turn the Moon Red

During the peak, 96 percent of the moon will be within the darkest part of our planet’s shadow. The orb will take on an eerie glow because of how sunlight gets filtered through Earth’s atmosphere

An artistic rendering of the Neil Gehrels Swift Observatory, which is now falling after watching the sky for more than 20 years.

NASA-Funded Mission to Rescue a Falling Space Telescope Officially Ends in Failure

The commercial LINK spacecraft was supposed to give NASA’s Swift observatory a boost, pushing it higher into orbit to extend its life. But after launch, LINK experienced several problems. Swift is expected to re-enter Earth’s atmosphere and burn up by the end of this year

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

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

NASA Completes Daring ‘Big Bang’ Fix on the Voyager 2 Probe, Allowing It to Keep Studying Interstellar Space

Scientists swapped three of the probe’s heating devices for ones that use less energy, and they might do the same with Voyager 1. Both spacecraft launched almost 50 years ago

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

Meteors from the Perseids streaking above Inyo National Forest in Bishop, California, in 2024.

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

The pen and the broken circuit breaker switch sold at auction.

Buzz Aldrin Used This Humble Felt-Tip Pen to Save the Apollo II Astronauts. It Just Sold for More Than $850,000

In July 1969, a quick-thinking Aldrin used the writing instrument to rearm the engine arm circuit of the lunar module “Eagle” after the switch broke off during the moon landing

A fragment of the Hillsborough meteorite

This Meteorite Crashed Into a New Jersey Home in 2024. Now, Scientists Say It Contains Some of the Building Blocks of Life

The Hillsborough meteorite belongs to a rare class of rocks from space, according to a new study. It holds amino acids and other organic compounds, as well as evidence of salty water

An illustration of the Beta Pictoris system features the newly discovered planet, Beta Pictoris d, at the right. Its orbit is wider than those of the two other known planets moving around its star.

Astronomers Noticed a Mysterious Spot Appearing in Telescope Images. It Turned Out to Be the Faintest Exoplanet Ever Imaged From Earth

The gas giant, called Beta Pictoris d, had been hiding in plain sight for more than a decade, until two independent teams verified its existence

A view of the uncrewed Orion capsule in space during the 2022 Artemis 1 mission, with both the Earth and moon in the background. The Earth looks smaller because it is farther away.

Artemis 1’s Orion Spacecraft Withstood the Heat of Re-entry in a Critical Test for Humans’ Return to the Moon. Now, NASA Will Lend the Historic Capsule to the Smithsonian’s National Air and Space Museum

The exact timeline for the spacecraft’s display hasn’t been announced, but the artifact will fit into an upcoming exhibition on how humans have built a long-term presence in Earth orbit and laid the groundwork for farther space travel

Asteroid Torifune as seen by Hayabusa2 from a little more than half a mile away

New Images Reveal That This Asteroid Is Actually Two Conjoined Space Rocks. They Form a Peanut-Shaped Object Called a ‘Contact Binary’

A flyby conducted by the Japanese spacecraft Hayabusa2 uncovered the asteroid’s strange shape. Data gathered by the probe will also help defend the planet against potentially threatening space rocks

Strange, metallic-looking spheres recently washed ashore in Queensland, Australia.

Strange Spheres Washed Ashore on an Australian Beach. Authorities Say They’re Probably ‘Space Balls’—Empty Fuel Vessels From a Rocket

The shiny objects—each roughly twice the size of a basketball—began to appear on July 3. Authorities initially worried that they were hazardous but have since determined that they’re likely safe bits of space junk
