Astronauts To Patch Up NASA’s NICER Telescope

NASA is planning to repair NICER (Neutron star Interior Composition Explorer), an X-ray telescope on the International Space Station, during a spacewalk later this year. It will be the fourth science observatory in orbit serviced by astronauts.

NASA’s Roman Space Telescope’s ‘Eyes’ Pass First Vision Test

Engineers at L3Harris Technologies in Rochester, New York, have combined all 10 mirrors for NASA’s Nancy Grace Roman Space Telescope. Preliminary tests show the newly aligned optics, collectively called the IOA (Imaging Optics Assembly), will direct light into Roman’s science instruments extremely precisely.

NASA Observations Find What Helps Heat Roots of ‘Moss’ on Sun

Did you know the Sun has moss? Due to its resemblance to the earthly plants, scientists have named a small-scale, bright, patchy structure made of plasma in the solar atmosphere “moss.” This moss, which was first identified in 1999 by NASA’s TRACE mission, blossoms around the center of a sunspot group, where magnetic conditions are […]

NASA’s Fermi Mission Sees No Gamma Rays from Nearby Supernova

A nearby supernova in 2023 offered astrophysicists an excellent opportunity to test ideas about how these types of explosions boost particles, called cosmic rays, to near light-speed. But surprisingly, NASA’s Fermi Gamma-ray Space Telescope detected none of the high-energy gamma-ray light those particles should produce.

NASA’s LRO Observes 2024 Solar Eclipse Shadow

Editor’s Note, April 16, 2024: This story has been updated to remove an unclear secondary image and caption. As the Moon blotted out the Sun to viewers across the United States during the April 8 solar eclipse, NASA’s Lunar Reconnaissance Orbiter (LRO) captured an image from some 223,000 miles away of the highly anticipated celestial […]

The April 8 Total Solar Eclipse: Through the Eyes of NASA

On April 8, 2024, the Moon’s shadow swept across North America, treating millions to a breathtaking view of a total solar eclipse. As the Moon passed in front of the Sun, it revealed the Sun’s wispy white outer atmosphere — the corona. Pictures of total solar eclipses are beautiful — they capture a moment happening […]
