Galaxies Collide ~ Top right is M31, the Andromeda Galaxy, 2.5 million light-years away. Bright yellow star at the center is Mirach, beta star in the constellation Andromeda. Bottom left is M33, the Triangulum Galaxy, is also about 3 million light years away. Although they look far apart, M31 and M33 are engaged in a gravitational struggle. Radio astronomers have found indications of a bridge of neutral hydrogen gas that could connect the two, evidence of a closer encounter in the past…
The Andromeda Galaxy (M31) is the closest large galaxy to the Milky Way and is one only ten galaxies that can be seen unaided from the Earth. In approximately 4.5 billion years the Andromeda Galaxy and the Milky Way are expected to collide. It is accompanied by at least 10 satellite galaxies the most notable of which is the Triangulum Galaxy.
Here’s the star Mirach in Andromeda again. Notice that the Triangulum galaxy is about equidistant from this star as the Andromeda galaxy. Once you find Mirach and the Andromeda galaxy, note that a line between them points, more or less, to the Triangulum galaxy. Via ESO Public Outreach
Galaxy Love looking at photos of galaxies. Intriguing and so far away....This looks like fairies dancing in the moonlight! I know the scientists will be mortified by that description but it's just so beautiful! Sorry :)
Astronomy Picture of the Day: 01/16/14 - The Triangulum Galaxy This is the picturesque Triangulum Galaxy (also known as M33), which is located approximately 3 million light-years from Earth in the constellation of Triangulum. It stretches 50,000 light-years across and is one of the most distant objects that can be seen by the naked eye. Meaning, you would likely see it as a single star, when it's really a galaxy with billions of stars spread throughout. M33 is the third
Unsolved Mystery of Molecules Found in Andromeda & Triangulum Galaxies In the summer of a team of NASA and European scientists recorded the "fingerprints" of mystery molecules in two distant galaxies, Andromeda and the Triangulum (image
