NASA's InSight Mars lander took this final selfie on April 24, 2022, the 1,211th Martian day, or sol, of the mission. The lander is covered with far more dust than it was in its first selfie, taken in December 2018, not... Continue Reading →
The center of the Lagoon Nebula is a whirlwind of spectacular star formation. Visible near the image center, at least two long funnel-shaped clouds, each roughly half a light-year long, have been formed by extreme stellar winds and intense energetic starlight. A tremendously bright nearby star, Herschel 36,... Continue Reading →
The Earth Surface Mineral Dust Source Investigation (EMIT) is an Earth Ventures-Instrument (EVI-4) Mission to map the mineral composition of arid dust source regions via imaging spectroscopy in the visible and short-wave infrared. The maps of the source regions will... Continue Reading →
DART is the first-ever mission dedicated to investigating and demonstrating one method of asteroid deflection by changing an asteroid’s motion in space through kinetic impact. This method will have DART deliberately collide with a target asteroid—which poses no threat to... Continue Reading →
This new NASA Hubble Space Telescope image of IC 4271, also known as Arp 40, is a curious pair of spiral galaxies some 800 million light-years away. The smaller galaxy is superimposed on the larger one, which is a type... Continue Reading →
On May 11, 2022, the National Oceanic and Atmospheric Administration, or NOAA, shared the first images of the Western Hemisphere from its Geostationary Operational Environmental Satellite-T (GOES-T). Later designated GOES-18, the satellite’s Advanced Baseline Imager (ABI) instrument recently captured stunning views... Continue Reading →
Stars born with more than about 20 times the Sun’s mass end their lives as black holes. As the name implies, black holes don’t glow on their own because nothing can escape them, not even light. Until 2015, when astronomers... Continue Reading →
In this image from April 10, 2022, sunlight glints off the Atlantic Ocean in this photograph from taken by the crew of the International Space Station as it orbited 262 miles above. Every 24 hours, the space station makes 16 orbits of Earth,... Continue Reading →
The researchers observed unexpected, rapid "electron precipitation" from low-Earth orbit using the ELFIN mission, a pair of tiny satellites built and operated on the UCLA campus by undergraduate and graduate students guided by a small team of staff mentors. By... Continue Reading →
