2023年5月24日 · Out of all of these, the Andromeda galaxy is the closest one to us. It is approximately 2.5 million light-years away. Because it is our galactic neighbor, astronomers are constantly trying to find out answers to the questions we all have about Andromeda. Does it have any planets? What do they look like? Are they habitable?

The Andromeda Galaxy is a barred spiral galaxy and is the nearest major galaxy to the Milky Way. It was originally named the Andromeda Nebula and is cataloged as Messier 31, M31, and NGC 224.

2025年1月16日 · This is the largest photomosaic ever made by the Hubble Space Telescope. The target is the vast Andromeda galaxy that is only 2.5 million light-years from Earth, making it the nearest galaxy to our own Milky Way. Andromeda is seen almost edge-on, tilted by 77 degrees relative to Earth’s view.

The Andromeda Galaxy, also known as Messier 31 or M31, is a spiral galaxy located about 2.5 million light-years (2.4×10 19 km) from Earth. Located in the Andromeda constellation, it is the closest spiral galaxy to the Milky Way, where our solar system is, although it isn't the closest overall galaxy to the Milky Way.

2023年10月26日 · The Andromeda galaxy is the most distant object in the sky that you can see with your unaided eye. It's also on a collision course with our Milky Way.

2025年1月16日 · 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 very clear autumn night as a faint cigar-shaped object roughly the apparent ...

2025年1月24日 · Andromeda Galaxy, great spiral galaxy in the constellation Andromeda, the nearest large galaxy. It is one of the few visible to the unaided eye, appearing as a milky blur. The Andromeda Galaxy is located about 2,480,000 light-years from Earth, and its diameter is approximately 200,000 light-years.

2013年6月12日 · Andromeda, also known as Messier 31 (M31), is a spiral galaxy located about 2.5 million light years away. It is thought that the Milky Way and Andromeda will collide several billion years from now. The black holes located in both galaxies will then reside in the large, elliptical galaxy that results from this merger.

2019年11月14日 · The Andromeda galaxy has 25 satellite dwarf galaxies and is estimated to contain more than trillion stars within its two spiral arms. Like many other elliptical galaxies we observed, it has a black hole with more than 100 million solar masses in its center.
