How far away is M31?

The Andromeda Galaxy, also known as Messier 31, M31, or NGC 224 and originally the Andromeda Nebula, is a barred spiral galaxy with the diameter of about 46.56 kiloparsecs approximately 765 kpc from Earth and the nearest large galaxy to the Milky Way.

How far away is M31 Hubble?

Looking up "distance to M31" on the web, it is easy to find that the Andromeda galaxy (the other name for M31) is 2.5 million light years (or 2.5×10⁶ light years).

How far away is M31 in PC?

Three-color image of the nucleus of M31 with components labeled. The eccentric disk is demarcated by P1 at apoapse and P2 at periapse and contains old stars. The young nuclear cluster, P3, is centered on the SMBH and is prominent at blue wavelengths. 1″ is ∼4 pc at M31's distance of 785 pc.

What does M31 mean in astronomy?

The 1.5 billion pixels in the mosaic reveal over 100 million stars and thousands of star clusters embedded in a section of the pancake-shaped disk of M31, also known as the Andromeda galaxy.

How far away is M31 the Andromeda galaxy?

At approximately 2.5 million light-years away, the Andromeda galaxy, or M31, is our Milky Way's largest galactic neighbor.

The Terrifying Truth About the Andromeda Galaxy

Is M31 in our galaxy?

The measured distance put Andromeda firmly outside the Milky Way. Modern measurements have put the Andromeda galaxy at about 2.5 million light years from Earth. Want to know even more about M31?

Will the Milky Way collide with M31?

Perhaps the most well-known collision in the Milky Way's neighborhood has yet to happen. The massive Andromeda Galaxy, also known as M31, will smash into us in about 4 billion years.

Is M31 bigger than the Milky Way?

But the Andromeda galaxy is a whole separate galaxy, even bigger than our Milky Way. In a dark sky, you can see that it's big on the sky as well, a smudge of distant light larger than a full moon.

How far can Hubble see into universe?

How far can Hubble see? The farthest observation that Hubble has made to date is of the galaxy GN-z11, which is located about 13.4 billion light-years away.

What are the 4 types of galaxies?

The smallest of galaxies contain a “mere” few hundred million stars while the largest galaxies contain up to one hundred trillion stars! Scientists have been able to segment galaxies into 4 main types: spiral, elliptical, peculiar, and irregular.

How far can Hubble see back?

The Hubble Space Telescope can see back roughly 1 billion years. On the far right of the timeline is the modern universe at 13.7 billion years old.

Does life exist in Andromeda Galaxy?

Can the Andromeda Galaxy support life? Since we can't yet say for certain whether there are any other stars in our own galaxy that host life, it is even harder to say whether there might be life, or at least the conditions for life, in another galaxy.

Does Andromeda have a black hole?

Astronomers confirm intermediate-mass black hole in Andromeda galaxy. Astronomers at the University of Utah have confirmed an intermediate-mass black hole, an elusive rarity long sought by scientists. The object is hidden in B023-G078, a star cluster in the Andromeda galaxy, the nearest spiral galaxy.

How many galaxies are in M31?

The Andromeda Galaxy (M31) has satellite galaxies just like the Milky Way. Orbiting M31 are at least 13 dwarf galaxies: the brightest and largest is M110, which can be seen with a basic telescope.

Will humans survive Andromeda collision?

Q. Will humans survive the Andromeda collision? A: There is a 1 in 400,000 chance that humans will survive the Andromeda collision.

Is Andromeda coming towards us?

The Andromeda–Milky Way collision is a galactic collision predicted to occur in about 4.5 billion years between the two largest galaxies in the Local Group—the Milky Way (which contains the Solar System and Earth) and the Andromeda Galaxy.

How long will our galaxy last?

Four billion years from now, our galaxy, the Milky Way, will collide with our large spiraled neighbor, Andromeda. The galaxies as we know them will not survive. In fact, our solar system is going to outlive our galaxy.

Is M31 a black hole?

Using the orbiting Chandra X-Ray Observatory, astronomers have monitored the black hole, known as M31* (“M31-star,” for another name for the galaxy), since late 1999.

Who is the oldest planet?

What is the oldest planet in the Solar System? The first to form, possibly within the first 3 million years of the Solar System, is Jupiter.

Does M31 have a black hole?

The Andromeda Galaxy, also called M31, is a huge spiral galaxy fairly close in size and mass to our own Milky Way. Like the Milky Way it also has a central bulge of stars, and a supermassive black hole in its very core.

What is the biggest galaxy?

A spectacular new photo has been released showing the record-holder for largest galaxy in the universe. NGC 6872, also known as the Condor Galaxy, stretches 522,000 light years from tip to tip.

What galaxy is Earth in?

We live on a planet called Earth that is part of our solar system. But where is our solar system? It's a small part of the Milky Way Galaxy. A galaxy is a huge collection of gas, dust, and billions of stars and their solar systems.

Can you enter the Andromeda Galaxy?

To reach M31, the Andromeda galaxy, in a human lifetime would require a velocity of 0.99999 c. Behind the relativistic spacecraft on Earth, millions of years would have passed, but the same crew that departed would reach their destination.
