What looks like a teleporter from science fiction being draped over NASA's James Webb Space Telescope, is actually a "clean tent." The clean tent protects Webb from dust and dirt when engineers at NASA's Goddard Space Flight Center transport the telescope out of the relatively dust-free cleanroom and into the vibration and acoustics testing areas.
The primary mirror of NASA's James Webb Space Telescope that consists of 18 hexagonal mirrors looks like a giant puzzle piece standing in the massive clean room of NASA's Goddard Space Flight Center in Greenbelt, Maryland. The telescope will help piece together puzzles scientists have been trying to solve throughout the cosmos.
Engineers and technicians working on the James Webb Space Telescope successfully completed the first important optical measurement of Webb’s fully assembled primary mirror, called a Center of Curvature test.
NASA's Kepler and Swift missions have found rapidly rotating stars producing more than 100 times our own sun's peak X-ray emission. Spinning so fast they resemble pumpkins, the stars likely formed by mergers of sun-like stars.
Via a NASA-led citizen science project, eight people with no formal training in astrophysics helped discover what could be a fruitful new place to search for planets outside our solar system – a large disk of gas and dust encircling a star known as a circumstellar disk.
NASA's search for planets outside of our solar system has mostly involved very distant, faint stars. The upcoming Transiting Exoplanet Survey Satellite, by contrast, will look at the brightest stars in our solar neighborhood.
Scientists have found the first gamma-ray binary in another galaxy and the most luminous one ever seen. The dual-star system is in a small nearby galaxy and contains a massive star and a crushed stellar core that interact to produce a flood of gamma rays, the highest-energy form of light.
Astronomers using NASA's Hubble Space Telescope have imaged what may be water vapor plumes erupting off the surface of Jupiter's moon Europa. This finding bolsters other Hubble observations suggesting the icy moon erupts with high altitude water vapor plumes.
