Can Andromeda be seen without a telescope?
A handful of the 300 billion stars in the Andromeda Galaxy go nova each year. The Andromeda Galaxy is the only galaxy you can see without a telescope from the Northern Hemisphere. From a dark site, it looks like a faint, fuzzy patch in the sky, and it is easy to find with binoculars.
Is Andromeda larger than the moon?
You will see that Andromeda is many times bigger than the moon in diameter. Andromeda is actually about 220,000 light years across and at 2.5 million light years will subtend an angle around ten times wider than the moon, 5 degrees.
How large is Andromeda in the sky?

How come we can see the Andromeda Galaxy even though its 2.5 million light years away?
Answer: You are correct. Due to the “universal speed limit” for the transport of information in the universe, the speed of light, we see objects in space as they were in the past. The Andromeda galaxy is about 2.5 million light years away, so we see it as it was 2.5 million years ago.
Is Andromeda Galaxy bigger than Milky Way?
By some estimates, the Andromeda Galaxy contains roughly one trillion stars. 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 Galaxy visible?
At 2.5 million light-years from Earth, the Andromeda Galaxy is the most distant object visible with the naked eye. It’s the closest major galaxy to the Milky Way, and can only be seen if you have a really dark sky. With the naked eye, Andromeda will be extremely faint.
Is Andromeda bigger than the Milky Way?
Is Andromeda smaller than the Milky Way?
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.
Can you see the Andromeda with the naked eye?
At 2.5 million light-years from Earth, the Andromeda Galaxy is the most distant object visible with the naked eye. It’s the closest major galaxy to the Milky Way, and can only be seen if you have a really dark sky.
How Andromeda looks to the naked eye?
html. 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.
Where is Andromeda Galaxy in the sky?
RA 0h 42m 44s | Dec +41° 16′ 9″
Andromeda Galaxy/Coordinates
Is Andromeda the biggest galaxy?
The Andromeda Galaxy is the largest galaxy of the Local Group, which, in addition to the Milky Way, also contains the Triangulum Galaxy and about 30 other smaller galaxies.
Is Andromeda bigger than the Moon?
Here’s another one featured in NASA’s Astronomy Picture of the Day: Andromeda—or M31—is larger than our Milky Way (although not as massive, if you count the dark matter in our galaxy.) It’s 2.5 million light-years from us, while the Moon is only 384,400 kilometers away. Now think that a light-year is 9.5 trillion kilometers.
How big is the Andromeda Galaxy compared to the Milky Way?
Andromeda is the closest large galaxy to us. At 140,000 light years across, it’s 40\% bigger than our 100,000 light year diameter Milky Way. Andromeda is 2.5 million light years away from us, or about 25 Milky Way diameters.
What does the Andromeda Galaxy look like with binoculars?
You’ve just landed on the Andromeda galaxy, which looks like a smudge of light to the unaided eye. If you can’t see the Andromeda galaxy with the eye alone, by all means use binoculars. The Great Andromeda Nebula, photographed in the year 1900. At this point, astronomers couldn’t discern individual stars in the galaxy.
How many light years away is Andromeda?
Andromeda is 2.5 million light years away from us, or about 25 Milky Way diameters.
