NASA’s Hubble Provides Bird’s-Eye View of Andromeda Galaxy’s Ecosystem

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 don’t see is a swarm of nearly three dozen small satellite galaxies circling the Andromeda galaxy, like bees around a hive.

NASA’s Hubble Traces Hidden History of Andromeda Galaxy

In the years following the launch of NASA’s Hubble Space Telescope, astronomers have tallied over 1 trillion galaxies in the universe. But only one galaxy stands out as the most important nearby stellar island to our Milky Way — the magnificent Andromeda galaxy (Messier 31). It can be seen with the naked eye on a […]

NASA Celebrates Edwin Hubble’s Discovery of a New Universe

For humans, the most important star in the universe is our Sun. The second-most important star is nestled inside the Andromeda galaxy. Don’t go looking for it — the flickering star is 2.2 million light-years away, and is 1/100,000th the brightness of the faintest star visible to the human eye. Yet, a century ago, its […]

Spitzer Space Telescope Captures Galactic Snack

This image, released on May 9, 2024, from NASA’s retired Spitzer Space Telescope shows streams of dust flowing toward the supermassive black hole at the heart of the Andromeda Galaxy. These dust streams can help explain how black holes billions of times the mass of our Sun can satiate their big appetites but remain “quiet” […]

NASA Images Help Explain Eating Habits of Massive Black Hole

Data from NASA’s retired Spitzer Space Telescope has given scientists new insights into why some supermassive black holes shine differently than others. In images from NASA’s retired Spitzer Space Telescope, streams of dust thousands of light-years long flow toward the supermassive black hole at the heart of the Andromeda galaxy.
