to Galileo Galilei who was born on this day in 1564! His observations revolutionized the field of astronomy including his discovery of Jupiter's four largest moons. This video shows 3 of the 4 "Galilean moons" as observed by Hubble in 2015…

Hubble has captured the smoking gun of a newborn star! These five objects, visible in blue in the top center of the image, lie within NGC 1333, a reflection nebula full of gas and dust found about a thousand light-years away from Earth: …

in 1997, astronaut Steve Hawley, who deployed Hubble using the space shuttle's robotic arm in 1990, used the shuttle's arm to capture Hubble from orbit in preparation for its second servicing mission.

On International Day of Women & Girls in Science we remember the "Mother of Hubble," Nancy Grace Roman, who passed away in December at the age of 93. Despite discouragement, she studied math & science and became NASA’s 1st chief astronomer.

Astronomers used the foreground galaxy cluster, SDSS J0915+3826, to study star formation in galaxies lying so far away that their light has taken up to 11.5 billion years to reach Earth: go.nasa.gov/2N0wpos

During its routine yearly monitoring of the weather on our solar system's outer planets, Hubble uncovered a new mysterious dark storm on Neptune and provided a fresh look at a long-lived storm circling around the north polar region on Uranus: …

9 years ago, scientists released this map of Pluto, made from Hubble observations, providing details about Pluto's surface 5 years before NASANewHorizons made its historic flyby: go.nasa.gov/2GoPHCr

This image reveals an ancient, glimmering ball of stars called NGC 1466. It is a globular cluster that is slowly moving through space on the outskirts of the Large Magellanic Cloud, one of our closest galactic neighbors: …

Because of its 13-billion-year-old age, and its isolation — which resulted in hardly any interaction with other galaxies — this dwarf spheroidal galaxy is the astronomical equivalent of a living fossil from the early universe: go.nasa.gov/2G1wOGa

The sharpest view of the Orion Nebula ever captured by Hubble revealed never-before-seen stars, swirls of gas shaped by massive stars born in the giant stellar nursery, and dusty disks around young stars where planets might also be forming…

Hubble spotted a wayward spiral galaxy losing its gas as it plunges toward the center of the massive cluster and is roughed up as it plows through the intergalactic medium: hubblesite.org/news_release/ne

Wide Field Camera 3 was brought back to full operational status and completed its first science observations just after noon EST today.

NASA has moved closer to conducting science operations again with the Wide Field Camera 3 instrument, which suspended operations on Tuesday, Jan. 8. Today the instrument was brought back to its operations mode. For more details: nasa.gov/feature/goddard/2019/

NASA continues to work toward recovering the Wide Field Camera 3 instrument, which suspended operations on Tuesday, January 8 due to voltage levels within the instrument that were out of range. For more details: nasa.gov/feature/goddard/2019/

This very distant quasar has been magnified and split into three images due to the gravitational field of a foreground galaxy. The quasar would have gone undetected if not for the power of gravitational lensing, which boosted its brightness 50x

At 17:23 universal time, the Wide Field Camera 3 suspended operations due to a hardware problem. Hubble will continue to perform science with its other instruments while the Wide Field Camera 3 anomaly is investigated: nasa.gov/feature/goddard/2019/

These 2 images, taken 6 years apart, show fast-moving blobs of material sweeping outwardly through a debris disk around the young, nearby red dwarf star AU Microscopii. Red dwarfs are the most abundant & longest-lived stars in our Milky Way galaxy

Hubble has produced its largest mosaic image ever of the Triangulum galaxy!

Triangulum seems to have had minimal interaction with other galaxies, maintaining a neat, organized spiral and plenty of material for churning out new stars

This festive image resembles a holiday wreath made of sparkling lights. The bright southern hemisphere star RS Puppis, at the center of the image, is swaddled in a gossamer cocoon of reflective dust illuminated by the glittering star: …
