For the last time while it is on Earth, the world’s largest and most powerful space science telescope opened its iconic primary mirror. This event marked a key milestone in preparing the observatory for launch later this year. As part of NASA’s James Webb Space Telescope’s final tests, the 6.5 meter (21 […]

NASA’s OSIRIS REx Asteroid Sample Return Mission. Credit: NASA’s Goddard Space Flight Center After nearly five years in space, NASA’s Origins, Spectral Interpretation, Resource Identification, Security, Regolith Explorer (OSIRIS-REx) spacecraft is on its way back to Earth with an abundance of rocks and dust from the near-Earth asteroid Bennu. On Monday, […]

Heart of darkness: A view of the accretion disc around the supermassive black hole, with jet-like structures flowing away from the disc. The extreme mass of the black hole bends spacetime, allowing the far side of the accretion disc to be seen as an image above and below the black […]

Both sides of the James Webb Space Telescope’s sunshield were lifted vertically in preparation for the folding of the sunshield layers.

These four images taken by NASA’s Hubble Space Telescope reveal the chaotic birth of stars in the Orion complex, the nearest major star-forming region to Earth. The protostars were photographed in near-infrared light by Hubble’s Wide Field Camera 3. The images were taken November 14, 2009, and January 25, February […]

Formerly known as WFIRST, the Wide Field Infrared Survey Telescope, the Roman Space Telescope is a NASA observatory designed to perform wide field imaging and surveys of the near infrared (NIR) sky.

Parker Solar Probe observed switchbacks — traveling disturbances in the solar wind that caused the magnetic field to bend back on itself — an as-yet unexplained phenomenon that might help scientists uncover more information about how the solar wind is accelerated from the Sun.

An illustration shows NASA’s Juno spacecraft as it entered orbit of Jupiter on July 4, 2016, after traveling for nearly five years and more than 1.7 billion miles. Credit: NASA/JPL/SwRI Data from the NASA spacecraft’s journey to Jupiter suggests that Mars may be shedding dust into interplanetary space. Look up to the night sky just before […]
