NASA has awarded the Total and Spectral Solar Irradiance Sensor-2 (TSIS-2) Spacecraft contract to General Atomics Electromagnetic Systems Group of San Diego, California.

NGC 2275 is classified as a flocculent (or fluffy-looking) spiral galaxy, located 67 million light-years away in the constellation of Cancer. Millions of bright, young, blue stars shine in the complex, feather-like spiral arms, interlaced with dark lanes of dust.

On behalf of the National Oceanic and Atmospheric Administration (NOAA), NASA has awarded the Space Weather Follow On-Lagrange 1 (SWFO-L1) Solar Wind Plasma Sensor (SWiPS) contract to South West Research Institute (SwRI) in San Antonio, Texas.

Hitching a ride on the Mars Pathfinder mission, the Sojourner rover arrived on Mars on July 4, 1997.

The Moon’s subsurface might be richer in metals, like iron and titanium, than researchers thought.

On June 26, 2020, NASA astronauts Bob Behnken and Chris Cassidy conducted the first of two spacewalks to swap batteries and upgrade power systems on the International Space Station.

KELT-9 b is one of the hottest planets known. New measurements from NASA's Transiting Exoplanet Survey Satellite (TESS) have enabled astronomers to greatly improve their understanding of this bizarre world.

NASA mission helps scientists identify when the Moon is unprotected from charged particles in space.

June 30 is Asteroid Day.

NASA has awarded the Visible Infrared Imaging Radiometer Suite (VIIRS) Atmosphere Science Investigator-led Processing System (SIPS) contract to the University of Wisconsin in Madison.

Dust storms from Africa’s Saharan Desert traveling across the Atlantic Ocean are nothing new, but the current dust storm has been quite expansive and NASA satellites have provided a look at the massive June plume.

We don’t see the beautiful spiral arms of galaxy NGC 5907 in this Hubble image because we are viewing it edge-on, like looking at the rim of a plate. It is for this reason that NGC 5907 is also known as the Knife Edge galaxy.

NASA’s Hubble Space Telescope observed a young star’s unseen, planet-forming disk casting a huge shadow across a more distant cloud in a star-forming region – like a fly wandering into a flashlight beam shining on a wall. The feature was dubbed the “Bat Shadow” because it resembles a pair of wings. Now, scientists see the Bat Shadow flapping!

In response to the global coronavirus (COVID-19) pandemic, NASA, ESA (European Space Agency), and JAXA (Japan Aerospace Exploration Agency) have joined forces to use the collective scientific power of their Earth-observing satellite data to document planet-wide changes in the environment and human society.

Astronomers using data from NASA's TESS and retired Spitzer Space Telescope have discovered a planet as large as Neptune circling the young star orbiting AU Microscopii.

As of June 2020, NASA’s Solar Dynamics Observatory – SDO – has now been watching the Sun non-stop for over a full decade. From its orbit in space around Earth, SDO has gathered 425 million high-resolution images of the Sun, amassing 20 million gigabytes of data over the past 10 years and enabling countless new discoveries about our closest star.

Although many other observatories, including NASA's Hubble Space Telescope, have previously created "deep fields" by staring at small areas of the sky for significant chunks of time, the Cosmic Evolution Early Release Science (CEERS) Survey, led by Steven L. Finkelstein of the University of Texas at Austin, will be the first for Webb.
