For decades, astronomers have known about irregular outbursts from the double star system V745 Sco, which is located about 25,000 light years from Earth. http://www.nasa.gov/sites/default/files/thumbnails/image/v745sco3d.jpg

NASA's Curiosity Mars Rover touched down eight years ago, on Aug. 5, 2012, and will soon be joined by a second rover, Perseverance. http://www.nasa.gov/sites/default/files/thumbnails/image/pia22486-main.jpg

This long-exposure photograph captures a starry sky above the Earth's atmospheric glow. http://www.nasa.gov/sites/default/files/thumbnails/image/iss063e065220.jpg

The barred spiral galaxy known as NGC 4907 shows its starry face from 270 million light-years away to anyone who can see it from the Northern Hemisphere. Appearing in this Hubble image to shine brightly below the galaxy is a star that is actually within our own Milky Way galaxy. http://www.nasa.gov/sites/default/files/thumbnails/image/potw2031a.jpg

If humans could travel to this giant planet, we would see a world still glowing from the heat of its formation with a color reminiscent of a dark cherry blossom, a dull magenta. http://www.nasa.gov/sites/default/files/thumbnails/image/1920px-astronomers_image_lowest-mass_exoplanet_around_a_sun-like_star.jpg

As of March 2020, our Mars Odyssey has captured these six views of the Martian moon Phobos. http://www.nasa.gov/sites/default/files/thumbnails/image/pia23893.jpg

Through the Artemis program, NASA is working to land the first woman and the next man on the Moon by 2024. http://www.nasa.gov/sites/default/files/thumbnails/image/ksc-20200810-ph-fmx01_0032.jpg

This past weekend, NASA astronaut and Expedition 63 Commander Chris Cassidy was no exception as he collected trash for disposal during weekend housekeeping activities. http://www.nasa.gov/sites/default/files/thumbnails/image/iss063e066984.jpg

Hi-RISE, the High-Resolution Imaging Science Experiment camera aboard NASA's Mars Reconnaissance Orbiter (MRO) captured this avalanche plunging down a 1,640-foot-tall cliff. http://www.nasa.gov/sites/default/files/thumbnails/image/3_avalanche_pia24035-1041.jpg

The versatile Canadarm2 robotic arm is poised to grapple and remove the HTV-9 resupply craft from the space station's Harmony module. http://www.nasa.gov/sites/default/files/thumbnails/image/iss063e070805.jpg

We're celebrating National Aviation Day! After all, we are the National Aeronautics and Space Administration. Aviation and aeronautics are as much a part of our mission as space travel. http://www.nasa.gov/sites/default/files/thumbnails/image/13_duensing_j_sc19_propellerslice_v0_no_label.png

Galaxy NGC 2442, seen here by the Hubble Space Telescope, is nicknamed the Meathook galaxy owing to its extremely asymmetrical and irregular shape. http://www.nasa.gov/sites/default/files/thumbnails/image/potw2033a.jpg

In this image, one of the radiation detectors for the Radi-N2 experiment floats in the space station. This device will help researchers explore the radition risk to humans in space. http://www.nasa.gov/sites/default/files/thumbnails/image/2_iss035e031921_0.jpg

A newly discovered, roughly Earth-sized planet orbiting our nearest neighboring star might be habitable, according to a team of astronomers using the European Southern Observatory's 3.6-meter telescope at La Silla, Chile. http://www.nasa.gov/sites/default/files/thumbnails/image/proximasurface.jpg
