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.
Can you see the Andromeda galaxy anywhere?
It can be seen from most places in the northern hemisphere, but the further north you go, the higher in the sky it will be. As with looking at any astronomical objects, ideally you need to find a location as far away from light pollution as possible, and (obviously) do so on a clear and cloudless night.
Where can I find Andromeda in the night sky?
Most people find the galaxy by star-hopping from the constellation Cassiopeia the Queen, a very noticeable M- or W-shaped pattern on the sky’s dome. You can also find the Andromeda galaxy by star-hopping from the star Alpheratz in the Great Square of Pegasus. Both methods will lead you to the galaxy.
Can you see Andromeda with eyes?
The Andromeda Galaxy is the most distant object that can be seen with the unaided eye. M31 has been estimated to be nearly 200,000 light-years in diameter, about 1 1/2 times as wide as our own Milky Way galaxy. Its bright nucleus is the hazy patch that is visible to the unaided eye.
Can we see another galaxy from Earth?
The answer is no – unless you count seeing the combined light of many billions of stars. From the Northern Hemisphere, the only galaxy outside our Milky Way that’s easily visible to the eye is the great galaxy in the constellation Andromeda, also known as M31.
What planets are in Andromeda?
Does the Andromeda Galaxy have planets? There is currently only one very strong candidate planet in the Andromeda Galaxy, temporarily named PA-99-N2. It was detected because of a microlensing event in 1999.
How big is Andromeda in the sky?
| Andromeda Galaxy | |
|---|---|
| Mass | (1.5±0.5)×1012 M ☉ |
| Number of stars | ~1 trillion (1012) |
| Size | ~220 kly (67 kpc) (diameter) |
| Apparent size (V) | 3.167° × 1° |
What is the nearest galaxy to Earth?
The closest known galaxy to us is the Canis Major Dwarf Galaxy, at 236,000,000,000,000,000 km (25,000 light years) from the Sun. The Sagittarius Dwarf Elliptical Galaxy is the next closest , at 662,000,000,000,000,000 km (70,000 light years) from the Sun.
How many galaxies can we see with your naked eyes?
In the best sky conditions, the naked eye (with effort) can see objects with an apparent magnitude of 8.0. This reveals about 43,197 objects in the sky. There are 9 galaxies visible to the naked eye that you might see when observing the sky, and there are about 13 nebulae that you might see.
Can we reach Andromeda?
Highly unlikely. Andromeda is 2.5 million light years away. Even if we managed to build a ship that could go 99.9999999999999% the speed of light, it’ll take 2.5 million years to get there.
What is the bigger than the universe?
No, the universe contains all solar systems, and galaxies. Our Sun is just one star among the hundreds of billions of stars in our Milky Way Galaxy, and the universe is made up of all the galaxies – billions of them.
How does Andromeda look to 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.
Can the earth survive Andromeda collision?
Originally Answered: Will our Earth be affected during the collision of the Milky Way and Andromeda galaxies? Andromeda galaxy and our own Milky Way galaxy are predicted to collide in the next four billion years or so, but our Earth will survive.
How old is the universe?
13.8 billion years old
After all, the age of the universe — determined from observations of the cosmic microwave background — is 13.8 billion years old, so how can a star be older than the universe?
How Fast Is Milky Way moving?
130 miles per second
When it comes to galaxies, how fast is fast? The Milky Way, an average spiral galaxy, spins at a speed of 130 miles per second (210 km/sec) in our Sun’s neighborhood. New research has found that the most massive spiral galaxies spin faster than expected.
Where is Earth in the Milky Way?
Orion Arm
Earth is located in one of the spiral arms of the Milky Way (called the Orion Arm) which lies about two-thirds of the way out from the center of the Galaxy. Here we are part of the Solar System – a group of eight planets, as well as numerous comets and asteroids and dwarf planets which orbit the Sun.
Is every star we see in our galaxy?
All the stars we see in the night sky are in our own Milky Way Galaxy. Our galaxy is called the Milky Way because it appears as a milky band of light in the sky when you see it in a really dark area.
How do we see distant galaxies?
When two galaxies lie nearly along the same line-of-sight, we can sometimes measure an effect called gravitational lensing, where the gravity of the closer galaxy bends the light passing near it from the more distant galaxy, which produces a magnified view of the more distant galaxy.
What is the closest star to Earth?
Proxima Centauri, the closest star to our own, is still 40,208,000,000,000 km away. (Or about 268,770 AU.)
Are we at the center of our galaxy?
The essential modern picture is that our solar system is located on the inner edge of a spiral arm, about 25,000 light-years from the center of the galaxy, which is in the direction of the constellation of Sagittarius.
Does Andromeda have a black hole?
The black hole was hidden within the star cluster B023-G078, in the Andromeda galaxy. It was originally thought to be a cluster of stars, but researchers now believe it is a stripped nucleus – a remnant of small galaxies that fell into bigger ones and had their outer stars stripped away by gravitational forces.
