The new composite image, which combines hundreds of photos from the Hubble Space Telescope, shows the Andromeda Galaxy with ...

Located 2.5 million light-years away, the majestic Andromeda galaxy appears to the naked eye as a faint, spindle-shaped object roughly the angular size of the full moon. What backyard observers ...

The Andromeda galaxy is also known as Messier 31. It is a spiral galaxy located about 2.5 million light-years from Earth. On ...

The combined programs collectively cover the entire disk of Andromeda, which is seen almost edge-on—tilted by 77 degrees relative to Earth’s view. Hubble can only detect stars brighter than our Sun, ...

“For example, Chandra’s X-rays reveal the high-energy radiation around the supermassive black hole at the center of M31 as ...

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 ...

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 ...

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 ...

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 ...

Scientists previously predicted the pair of galaxies would merge in about five billion years. Now, research suggests that ...

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 ...
