ALT A deep-space image of the Antennae Galaxies, two colliding galaxies with long, sweeping tidal tails extending far into space. The galactic cores glow brightly with blue and red hues, indicating regions of intense star formation. Faint, wispy trails of stars and gas arc across a dark backdrop speckled with distant galaxies and stars.

ALT The SUV-sized Perseverance rover took this selfie on April 6, 2021, the 46th Martian day, or sol, of the mission, with its WATSON camera. The rover's tire tracks are visible proceeding into the distance. The small Ingenuity rotocopter is situated on the Martian surface behind and to the left of the rover inside Jezero Crater. Exposed orange-y rocks and dirt cover the surface. The sky is a greyish peach color.

Hot science on a cold dwarf planet: Ceres may be cold now, but new research suggests it once had a lasting source of chemical energy. When combined with the briny water and carbon molecules found in its interior, Ceres may have been habitable. go.nasa.gov/45X1KSO
ALT The gray, cratered surface of Ceres fills most of the frame. Near the bottom left, one crater has small patches of much brighter material.
ALT A diagram of interior layers in Ceres. Beneath the cold surface and ice-rich crust is a reservoir of salty water, where water and gases released from the rocky core below mix with the organic molecules methane and carbon dioxide.
Today at 3 p.m. ET — we're talking about artificial intelligence in the search for life and our Habitable World Observatory. Join here to ask questions live: youtube.com/live/xioQbOcjaLo…
What will it take to find life on planets beyond our solar system? Our Habitable Worlds Observatory will be the first mission designed to find out! Share questions for Program Scientist Dr. Megan Ansdell and tune into #AskAstrobio on Aug. 14 at 3 p.m. ET: youtube.com/live/xioQbOcjaLo
ALT This artist’s concept of exoplanet TOI 700 d depicts a bright blue, ocean-covered world marbled with white clouds. The planet is tidally locked to its star, leaving one side in constant daylight and the other in darkness, fading into the black background.

A few interesting sights here:
- The abrasion patch made by the rover is 2 inches (5 centimeters) wide
- These tracks are about 300 feet (90 meters) away
- This peak is 40 miles (65 kilometers) away!

ALT A masterpiece of deep time and wrenching gravity, the tortured surface of Saturn's moon Enceladus and its fascinating ongoing geologic activity tell the story of the ancient and present struggles of one tiny world. Long cracks tear across the white, icy surface revealing ridges that look a light blue. Observations made by the Cassini spacecraft show that this small moon of Saturn has an ice-covered water ocean that erupts into space, forming plumes of material.
Are we alone? To find out, we’re building the Habitable Worlds Observatory. This powerful space telescope uses proven technologies from @NASAHubble, @NASAWebb, and @NASARoman to look for signatures of planets that can support life — and maybe life itself. go.nasa.gov/44KCbT7

ALT Illustration of a red dwarf star glowing with a deep red hue, surrounded by a faint red corona. The surface appears smooth with subtle yellowish patches, indicating cooler temperatures and minimal solar activity.
ALT Illustration of a K-type main-sequence star emitting a bright orange-yellow light. The star's surface shows a textured appearance with a noticeable sunspot near the top, suggesting moderate magnetic activity.
ALT Illustration of a G-type star radiating a bright yellow glow against the dark backdrop of space. Its surface is speckled with faint dark spots, hinting at sunspots caused by magnetic activity.

After a decade of searching, @NASAMars' MAVEN mission has directly observed sputtering—an atmospheric escape process where solar particles knock atoms out of the Martian atmosphere. This long-suspected process likely played a major role in stripping Mars of its thick atmosphere. go.nasa.gov/4kXn7bu
This finding helps explain how Mars transitioned from a potentially habitable world—with liquid water on its surface—to the cold, dry planet we see today. It’s a key piece in the astrobiology puzzle of whether life could have once existed on the Red Planet.
Where did Mars' water go? And why?
These questions have long puzzled scientists. Now, after a decade of searching, @NASAMars’ MAVEN has made the first direct observation of an elusive atmospheric escape process known as sputtering, offering new insight into the Red Planet’s mysterious water loss. go.nasa.gov/3Z4oUTB
