Can the earth survive an Andromeda collision?
Astronomers estimate that 3.75 billion years from now, Earth will be caught up amid the largest galactic event in our planet’s history, when these two giant galaxies collide. Luckily, experts think that Earth will survive, but it won’t be entirely unaffected.
Does Andromeda still exist?
The galaxy no longer exists as the large spiral structure it once was, but a remnant of it might still exist as an Andromeda satellite, called M32. Discovering and studying this decimated galaxy will help astronomers understand how disk galaxies like the Milky Way evolve and survive large mergers.
Can Andromeda destroy us?
“I think it’s unlikely the Earth will be physically destroyed by the collision with Andromeda,” Mackey said. “It’s not out of the question, but in general the stars in galaxies are spaced sufficiently sparsely that direct collisions between stars are rare.
How fast is Andromeda moving towards us?
per second
And that’s going to happen someday! The Andromeda galaxy is currently racing toward our Milky Way at a speed of about 70 miles (110 km) per second. Ultimately, the two galaxies will collide and merge.
Why is Andromeda moving toward us?
Based on Doppler shifting of its light, Andromeda is speeding toward us at 68 miles per second (110 kilometers per second). As Andromeda gets closer, the gravitational attraction between it and the Milky Way gets stronger and Andromeda accelerates in our direction.
Is Andromeda the nearest galaxy?
Although several dozen minor galaxies lie closer to our Milky Way, the Andromeda galaxy is the closest large spiral galaxy to ours. Excluding the Large and Small Magellanic Clouds, visible from Earth’s Southern Hemisphere, the Andromeda galaxy is the brightest external galaxy you can see.
Do you think there is life in the Andromeda Galaxy?
There are hundreds of billions of stars in the Andromena Galaxy. If even one in those one hundred stars have planets, and even one in those hundred, or even thousand planets could support life, there would be millions of chances for life to form.
Is the Andromeda galaxy visible to the unaided eye?
The Andromeda Galaxy, also known as Messier 31 or “the Great Spiral Galaxy” is one of the most distant objects that the unaided human eye can see. Use the constellations around the Andromeda Galaxy to help you pinpoint its location in the sky. You can see the galaxy faintly with your eyes,…
Are there any apps to find the Andromeda Galaxy?
There are many apps that can help you find the Andromeda Galaxy and other stars. These will adjust the star charts based on your position, hemisphere, season, and time of night. These include the Star Chart app, NightSky app, and GoSkyWatch. Locate the Cassiopeia constellation.
Is the Great Andromeda Nebula an external galaxy?
To support his claim of the Great Andromeda Nebula being, in fact, an external galaxy, Curtis also noted the appearance of dark lanes within Andromeda which resembled the dust clouds in our own galaxy, as well as historical observations of Andromeda Galaxy’s significant Doppler shift.
