What will happen when the Milky Way and Andromeda collide?
The result of the collision between Andromeda and the Milky Way will be a new, larger galaxy, but rather than being a spiral like its forebears, this new system ends up as a giant elliptical. The pair will end up forming a binary at the heart of the new, larger galaxy.
What is so special about the Andromeda Galaxy?
The Andromeda galaxy is the largest in the Local Group, where the Milky Way also belongs. Not only is this galaxy large, but it is also very massive. Its diameter is around 220,000 light-years and its mass equals the mass of 1,230 billion Suns! There are about one trillion stars in the Andromeda Galaxy.
Can there be life in the Andromeda Galaxy?
The answer to the first part of your question is no. So far, there have been no signs of ‘life’ – as fits our definition of it – detected in the Andromeda galaxy or any other galaxy. All the planets discovered so far – more than 5,000 – are within the Milky Way.
Does Andromeda mean ruler of men?
Her name is the Latinized form of the Greek Ἀνδρομέδα (Androméda) or Ἀνδρομέδη (Andromédē) ‘ruler of men’, from ἀνήρ, ἀνδρός (anēr, andrós) meaning ‘man, husband, human being’, and μέδω (medō) ‘I protect, rule over’.
What does Andromeda look like?
The Andromeda Galaxy is the most distant object you can see with your naked eyes, two million light years away. It is visible as a dim, fuzzy star from a dark sky site. With binoculars you can clearly see the elliptical shape of the galaxy. This star is the head of Andromeda.
Will humans ever leave the Milky Way?
The technology required to travel between galaxies is far beyond humanity’s present capabilities, and currently only the subject of speculation, hypothesis, and science fiction. However, theoretically speaking, there is nothing to conclusively indicate that intergalactic travel is impossible.
How do we know Andromeda exists?
To prove Andromeda existed outside the Milky Way, Hubble would need to measure how far away it was from Earth. All Hubble had to do was look for cepheid stars in Andromeda and make the appropriate calculations. Night after night, he took photographs of Andromeda with the enormous telescope, searching for cepheids.
