We Are NASA
We’ve taken giant leaps and left our mark in the heavens. Now we’re building the next chapter, returning to the Moon to stay, and preparing to go beyond. We are NASA – and after 60 years, we’re just getting started. Special thanks to Mike Rowe for the voiceover work.

New time-lapse movies from NASA’s NEOWISE mission give astronomers the opportunity to see objects, like stars and black holes, as they move and change over time. The videos include previously hidden brown dwarfs, a feeding black hole, a dying star, a star-forming region, and a brightening star. They combine more than 10 years of NEOWISE observations and 18 all-sky images, enabling a long-term analysis and a deeper understanding of the universe.

The NEOWISE mission uses a space telescope to hunt for asteroids and comets, including those that could pose a threat to Earth. Launched in December 2009 as the Wide-Field Infrared Survey Explorer, or WISE, the space telescope was originally designed to survey the sky in infrared, detecting asteroids, stars and some of the faintest galaxies in space. WISE did so successfully until completing its primary mission in February 2011.
Observations resumed in December 2013, when the telescope was taken out of hibernation and re-purposed for the NEOWISE project as an instrument to study near-Earth objects, or NEOs, as well as more distant asteroids and comets.

NASA's EPIC View of 2023 Eclipse Across America
From a million miles out in space, NASA’s Earth Polychromatic Imaging Camera (EPIC) captured 12 natural color images of the moon’s shadow crossing over North America.
EPIC is aboard NOAA’s Deep Space Climate Observatory (DSCOVR), where it photographs the full sunlit side of Earth every day, giving it a unique view of total solar eclipses.
