Saturn's Rings Will Temporarily Disappear From View in 2025

From Earth’s perspective, we’ll be looking at the gas giant’s rings edge-on, making them nearly impossible to see

The asteroid sample that is now on display at the National Museum of Natural History. By studying the retrieved space rocks, scientists aim to better understand how water and organic material first arrived on Earth.

How to See NASA's Bennu Asteroid Sample in Person

A tiny piece of the space rock made its public debut at the Smithsonian National Museum of Natural History, as scientists study the rest of the sample

The pair of asteroids, captured by NASA's Lucy spacecraft on November 1, 2023, from around 270 miles away.

NASA Finds a Surprise Second Asteroid During a Flyby Mission

While testing its tracking system, the agency's Lucy spacecraft discovered that Dinkinesh is not one space rock, but two

An image of Pluto taken by the New Horizons spacecraft in 2015

A Supervolcano on Pluto May Have Spewed Ice Just a Few Million Years Ago

An unusual crater on the dwarf planet hints at past volcanic activity—and a possible vast ocean beneath its surface, scientists say

Previous analyses of seismic activity on Mars suggested its core was surprisingly large, with a low density. Two new studies suggest the opposite.

Mars' Core May Be Smaller Than Thought, Wrapped in a Sea of Molten Rock

Based on seismic waves from a meteorite impact, two teams of scientists suggest the Red Planet has another layer deep beneath its surface

A photograph of the moon by the Apollo 17 crew on their return trip back to Earth. The new study analyzes material gathered from the lunar surface during the 1972 mission.

The Moon Is 40 Million Years Older Than Thought, Lunar Rock Samples Suggest

A new analysis of crystals from the moon pushes its age back to just 110 million years after the solar system formed

An artist's rendition of the Pysche asteroid. Data suggests that Psyche is between 30 and 60 percent metal, unlike any object in the solar system scientist's have observed up close before.

NASA Launches Mission to Study Distant Asteroid

The metal-rich object could hold clues about how our planet formed

An annular solar eclipse, captured by the solar optical telescope Hinode as the moon passed between it and the sun.

How to Watch the Annular 'Ring of Fire' Solar Eclipse on Saturday

A partial eclipse will be visible from all of the continental U.S., but only those in Oregon and the Southwest will have a chance to see the glowing ring

The capsule holding the asteroid sample shortly after touching down in the desert on September 24 at the Department of Defense's Utah Test and Training Range.

A Sample of Ancient Asteroid Dust Has Landed Safely on Earth

NASA's OSIRIS-REx mission retrieved bits of rock and dust from the asteroid Bennu, which could help scientists uncover the origins of life on our planet

Onlookers watch as a rocket carrying the Aditya-L1 spacecraft launches. The mission will study the sun's outer layers and the influence of solar activity on the solar system.

India Launches Mission to Study the Sun and Space Weather

The Aditya-L1 spacecraft will examine the star's outer layers and aim to shed light on its violent—and potentially damaging—storms

Neptune, captured by the Voyager 2 spacecraft. A new study finds a link between the planet's cloud coverage and solar activity.

Neptune's Clouds Have Disappeared, and the Sun Might Be Responsible

Scientists have linked shifts in the distant planet's cloud coverage to the ever-oscillating solar cycle, which is due to peak soon

The James Webb Space Telescope's first image of Saturn.

The new shot also features three of the planet's many moons, including Enceladus, a strong candidate for hosting life

Enceladus spews material from its ocean into space, which spacecraft from Earth can study to learn more about what lies below.

Scientists Find Phosphorus—a Key Element for Life—on a Saturn Moon

This is the last of six essential elements for life to be detected on Enceladus, giving the strongest indication yet that its ocean is habitable

Bryce Canyon is one of several national parks hosting stargazing and astronomy festivals this year.

These National Parks Are Hosting Stargazing Festivals in 2023

As more areas grow brighter with light pollution, national parks across the country have become dark-sky havens

U.S. Poet Laureate Ada Limón wrote a poem that will be brought to Jupiter's moon Europa.

Alongside Ada Limón's words, you can add your name to the spacecraft that will search for life on the icy moon

An image of Mars' surface captured by China's Zhurong rover, which landed in May 2021 and studied sand dunes near its landing site for nine months.

Sand Dune Features Hint at 'Recent' Water Flow on Mars

Between 1.4 million and 400,000 years ago, liquid salt water may have made cracks and crusts near the Martian equator, per data from China's Zhurong rover

One of Cassini's last looks at Saturn and its main rings from a distance, produced by combining images taken in October 2016.

Saturn's Rings May Be Younger Than Thought—and Disappearing

Data from NASA's Cassini mission points to the rings being no more than 400 million years old—quite young in the planet's 4.5-billion-year history

Saturn's rings and five of its moons, as captured by the Cassini spacecraft in 2011. The five moons, from left to right, are Janus, Pandora, Enceladus, Mimas and Rhea.

Saturn May Have Just Won the 'Moon Race' With 62 More Discovered

It will likely reign supreme as our solar system's planet with the most moons from now on, astronomers say

Dusty debris discs surround the young star Fomalhaut. The two innermost asteroid belts had never been seen before Webb revealed them.

James Webb Telescope Reveals Asteroid Belts Around Nearby Young Star

The findings suggest the star Fomalhaut may have orbiting planets hidden among its rings of debris

A person who discovered and approached the possible meteorite said it felt warm to the touch.
