Which is bigger Andromeda or Milky Way?

Which is bigger Andromeda or 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.

What is the difference between Andromeda and Milky Way?

The Andromeda galaxy contains about a trillion stars. Meanwhile, the Milky Way has about 300 billion stars. Stars from both galaxies will be thrown into new orbits around the newly merged galactic center.

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.

What will happen when the Andromeda and Milky Way collide?

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.

Which is older Andromeda or Milky Way?

And in terms of the stars present, the Andromeda galaxy’s stars are much older, and its star-formation rate is much lower: only about 20-30% that of 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.

Can Andromeda be seen from Earth?

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.

Are there humans in Andromeda galaxy?

In the Andromeda galaxy, it is generally accepted that humans originated from the Core World of Coruscant, but they have been found present as the dominant species on relatively unknown planets such as Ahch-To and Reylea, though the latter are more imbued with special properties than the rest of the galaxy.

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).

How Milky Way will end?

Someday our little corner of the universe will have a ringside seat for one of the biggest events in the cosmos. Two billion years from now, the Milky Way and Andromeda, our closest neighboring galaxy, will begin to fuse into one giant football-shaped galaxy.

Will the Earth be destroyed when we collide with Andromeda?

‘Andromeda has a much bigger and more complex stellar halo than the Milky Way, which indicates that it has cannibalised many more galaxies, possibly larger ones. ‘ However, Mackey told CNN that this event is unlikely to wreck havoc on our world.

How long will our Sun last?

So our Sun is about halfway through its life. But don’t worry. It still has about 5,000,000,000—five billion—years to go. When those five billion years are up, the Sun will become a red giant.

Is it possible to leave the Milky Way?

To escape the gravitational clutches of our galaxy, a spaceship would need to zoom out of our solar system and hit 537 kilometres per second. For context, a rocket needs to roar off at just 11.2 kilometres per second to escape Earth’s gravity. Conventional rocket engines would never make it.

Will humans travel to other galaxies?

Unfortunately, we’re unlikely to ever make contact with life in other galaxies. Travel by spaceship to our closest intergalactic neighbor, the Canis Major Dwarf, would take almost 750,000,000 years with current technology. Even a radio signal, which moves at close to the speed of light, would take 25,000 years.

Is there a black hole at the center of every galaxy?

Astronomers believe that supermassive black holes lie at the center of virtually all large galaxies, even our own Milky Way. Astronomers can detect them by watching for their effects on nearby stars and gas. This chart shows the relative masses of super-dense cosmic objects.

What universe is bigger than the Milky Way?

Galaxies come in many sizes. 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!

What is bigger than the Andromeda?

Until relatively recently, it was thought that our neighboring galaxy, Andromeda, was far larger than the Milky Way. But the Milky Way is, in fact, considerably larger than Andromeda.

Is Andromeda the largest galaxy?

The Andromeda Galaxy has a diameter of about 46.56 kpc (152,000 ly), making it the largest member of the Local Group in terms of extension….

Andromeda Galaxy
Type	SA(s)b
Mass	(1.5±0.5)×1012 M ☉
Number of stars	~1 trillion (1012)
Size	46.56 kpc (152 kly) (diameter; 25.0 mag/arcsec2 B-band isophote)

What star is bigger than the Milky Way?

The largest known star in the universe, UY Scuti is a variable hypergiant with a radius around 1,700 times larger than the radius of the sun. To put that in perspective, the volume of almost 5 billion suns could fit inside a sphere the size of UY Scuti.
