How big is the Milky Way compared to Andromeda?

How big is the Milky Way compared to Andromeda?

And it stretches more than 200,000 light-years in diameter. That’s significantly bigger than the Milky Way, which more recent estimates suggest is 150,000 light-years across (though the exact boundary of where either of these galaxies “end” is a bit nebulous).

Is Andromeda and Milky Way same size?

In terms of physical extent, the Andromeda Galaxy’s disk diameter is well-measured, and spans 220,000 light-years across. For comparison, the diameter of the Milky Way’s disk has long been thought to be only about half that: around 100,000 light-years.

How big is Andromeda compared to the Moon?

A photo of the full Moon from NASA’s Lunar Reconnaissance Orbiter is provided for scale: Andromeda has a diameter of about 3 degrees on the sky, while the Moon is about 0.5 degrees across. (In reality, the Moon is much smaller than Andromeda, but it is also a lot closer.)

Why is Andromeda bigger than the Milky Way?

because the Andromeda-Milky Way collision has already begun. The reason the collision is happening a few billion years ahead of schedule is that the Andromeda Galaxy is much bigger than it appears. The galaxy’s bright, starry disk is about 120,000 light years in diameter, making it slightly larger than the Milky Way.

Which is the biggest thing in universe?

The biggest single entity that scientists have identified in the universe is a supercluster of galaxies called the Hercules-Corona Borealis Great Wall. It’s so wide that light takes about 10 billion years to move across the entire structure.

How big is Andromeda’s black hole?

The object is hidden in B023-G078, a star cluster in the Andromeda galaxy, the nearest spiral galaxy. With a size of 100,000 solar masses, the B023-G078 intermediate-mass black hole is not as large as black holes at the center of galaxies, but larger than black holes caused by supernovae.

What is the largest galaxy ever discovered?

The Condor Galaxy is a colossal spiral galaxy disturbed by the smaller IC 4970. It is the largest known spiral galaxy with the isophotal diameter of over 717,000 light-years (220 kiloparsecs).

What is bigger than Milky Way?

The Milky Way is big, but some galaxies, like our Andromeda Galaxy neighbor, are much larger. The universe is all of the galaxies – billions of them!

Which is heavier Milky Way or Andromeda?

However, the latest research evens the score between the two galaxies. The study found the weight of the Andromeda is 800 billion times heavier than the Sun, on par with the Milky Way. The study used a new technique to measure the speed required to escape a galaxy.

How many years would it take to get to Andromeda?

How long would it take to get to the Andromeda Galaxy? Forget it! Although it may be one of the closest galaxies to our own, since the Andromeda Galaxy is 2.5 million light years distant it would take 2.5 million years to get there if (and it’s a huge ‘if’) we could travel at the speed of light.

Can humans see Andromeda?

The nearby Andromeda Galaxy, also called M31, is bright enough to be seen by the naked eye on dark, moonless nights. The Andromeda Galaxy is the only other (besides the Milky Way) spiral galaxy we can see with the naked eye.

What would Andromeda look like if we could see it?

If we could see Andromeda’s halo in the night sky, it would appear to be over 100 times the apparent diameter of the full Moon. We can’t see it, of course – not with our own eyes.

Will Andromeda destroy the Milky Way?

At five times the mass of the Large Magellanic Cloud, Andromeda could completely destroy the Milky Way when the two collide. That cosmic catastrophe is expected in about four billion years’ time.

Can the Earth survive the Milky Way Andromeda collision?

Andromeda–Milky Way collision The merger will totally alter the night sky over Earth but will likely leave the solar system unharmed, according to NASA.

Will the Milky Way ever crash with the Andromeda Galaxy?

Our Milky Way is on a collision course with another spiral galaxy called Andromeda. Today Andromeda is visible as a speck of light in the night sky, but about 5 billion years from now, it will be tangled up with us. Our galaxy’s spiral arms will disappear, and so will our supermassive black hole.

What’s the smallest thing in the universe?

Protons and neutrons make up the core, or nucleus, while teeny electrons cloud about the nucleus. Protons and neutrons can be further broken down: they’re both made up of things called “quarks.” As far as we can tell, quarks can’t be broken down into smaller components, making them the smallest things we know of.

What is beyond the universe?

The trite answer is that both space and time were created at the big bang about 14 billion years ago, so there is nothing beyond the universe. However, much of the universe exists beyond the observable universe, which is maybe about 90 billion light years across.

What is hottest thing in the universe?

A supernova is the hottest thing in the universe. The temperatures at the core during an explosion skyrocket up to 6000X the temperature of the sun’s core.

How many years will the Milky Way collide with Andromeda?

Our Milky Way galaxy is destined to collide with our closest large neighbour, the Andromeda galaxy, in about five billion years. Scientists can predict what’s going to happen.

How long until Andromeda hits the Milky Way?

Our Milky Way is on a collision course with another spiral galaxy called Andromeda. Today Andromeda is visible as a speck of light in the night sky, but about 5 billion years from now, it will be tangled up with us.

How long would it take to get from the Milky Way to Andromeda?

How long would it take to get to the Andromeda Galaxy? Forget it! Although it may be one of the closest galaxies to our own, since the Andromeda Galaxy is 2.5 million light years distant it would take 2.5 million years to get there if (and it’s a huge ‘if’) we could travel at the speed of light.

Is there anything bigger than the Milky Way?

The Milky Way is big, but some galaxies, like our Andromeda Galaxy neighbor, are much larger. The universe is all of the galaxies – billions of them!
