Hubble's sharp imaging capabilities can resolve more than 200 million stars in the Andromeda galaxy, detecting only stars brighter than our Sun. They look like grains of sand across the beach. But ...
The Andromeda galaxy is also known as Messier 31. It is a spiral galaxy located about 2.5 million light-years from Earth. On ...
This is the largest photomosaic ever assembled from Hubble Space Telescope observations. It is a panoramic view of the neighboring Andromeda galaxy, located 2.5 million light-years away. It took ...
Hubble, with its sharp imaging capabilities, detected more than 200 million stars in the Andromeda galaxy that are brighter than Earth's sun. But astronomers estimate the total population of stars ...

The new composite image, which combines hundreds of photos from the Hubble Space Telescope, shows the Andromeda Galaxy with more than 200 million individually resolved stars.
Together, PHAT and PHAST required more than 1,000 Hubble orbits to produce the 2.5-billion-pixel image of M31. This new data could help astronomers understand why Andromeda and the Milky Way could ...
A panoramic view of the neighboring Andromeda galaxy, located 2.5 million light-years away, requiring over 600 Hubble overlapping snapshots to stitch together.
The first program, the Panchromatic Hubble Andromeda Treasury (PHAT) program about a decade ago, obtained images at near-ultraviolet, visible, and near-infrared wavelengths using the Advanced Camera ...
While Andromeda, the closest galaxy to our Milky Way, is moving toward us, further measurements of other galaxies by Hubble and Belgian astronomer Georges Lemaître subsequently found that more ...
