Who first saw Andromeda?
Around the year 964, the Persian astronomer Abd al-Rahman al-Sufi was the first to describe the Andromeda Galaxy.
Can the Hubble Space Telescope can take pictures of individual stars in the Andromeda Galaxy?
Let its largest starcloud, NGC 206, show you the way. The Hubble Space Telescope easily resolves millions of individual stars in an outer region of the Andromeda Galaxy, also known as M31. At 2.5 million light-years away, you might think it’s impossible to see individual stars in the Andromeda Galaxy.

Do stars exist outside of galaxies?
Although stars cannot form in the voids between galaxies (since the density of matter is far too low), there are in fact large numbers of ‘intergalactic stars’. It has been estimated, for example, that 10 per cent of the mass of the Virgo galaxy cluster is in the form of these stellar interlopers.
What does the Andromeda Galaxy look like through a telescope?
Andromeda galaxy M31 looks like a dim, fuzzy star to the naked eye, and like a small elliptical cloud through binoculars. Through a telescope the Andromeda galaxy looks quite diffuse and it is possible to observe Andromeda’s satellite galaxies M32 and M110.
What will happen when our galaxy collides with Andromeda?
Here’s what will happen to Earth when our galaxy collides with the Andromeda Galaxy . “If two galaxies actually collide with each other, the stars basically pass right between each other, and the chance of two stars directly hitting each other is really, really small,” Van der Marel said in the video.
Is Andromeda a galaxy or constellation?
The Andromeda Galaxy (/ænˈdrɒmɪdə/), also known as Messier 31, M31, or NGC 224, is a spiral galaxy approximately 780 kiloparsecs (2.5 million light-years) from Earth, and the nearest major galaxy to the Milky Way . Its name stems from the area of the sky in which it appears, the constellation of Andromeda.
Is the Andromeda Galaxy an elliptical galaxy?
The Andromeda Galaxy (M31) is the closest large galaxy to the Milky Way and is one of a few 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 and the result will be a giant elliptical galaxy.
