How far is the Antennae galaxy from Earth?
about 62 million light years
The Antennae galaxies, located about 62 million light years from Earth, are shown in this composite image from the Chandra X-ray Observatory (blue), the Hubble Space Telescope (gold and brown), and the Spitzer Space Telescope (red).
What are the two orange blobs in the picture?
The orange blobs to the left and right of image center are the two cores of the original galaxies and consist mainly of old stars criss-crossed by filaments of dust, which appears brown in the image. These “tidal tails” were formed during the initial encounter of the galaxies some 200 to 300 million years ago.
What shape is an irregular galaxy?
Irregular galaxies have no particular shape. They are among the smallest galaxies and are full of gas and dust. Having a lot of gas and dust means that these galaxies have a lot of star formation going on within them.
What type of galaxy is Messier 101?
spiral galaxy
The Pinwheel Galaxy (also known as Messier 101, M101 or NGC 5457) is a face-on spiral galaxy 21 million light-years (6.4 megaparsecs) away from Earth in the constellation Ursa Major.
How many galaxies are there?
The deeper we look into the cosmos, the more galaxies we see. One 2016 study estimated that the observable universe contains two trillion—or two million million—galaxies. Some of those distant systems are similar to our own Milky Way galaxy, while others are quite different.
How many stars do you think are in our galaxy?
100 billion stars
In one calculation, the Milky Way has a mass of about 100 billion solar masses, so it is easiest to translate that to 100 billion stars. This accounts for the stars that would be bigger or smaller than our sun, and averages them out.
How old is M101?
M101 has an apparent visual magnitude of 7.86 and is approximately 20.9 million light years distant from Earth, which means that we are seeing it as it was about 20.9 million years ago. The Pinwheel Galaxy contains hundreds of billions of stars and is notable for its many large, bright star forming regions.
What kind of galaxy is an Antennae galaxy?
Antennae galaxies refer to a pair of spiral galaxies actually. These two galaxies are colliding at this very moment and have attained a weird shape. Let us learn 20 interesting Antennae Galaxies fact and figure out what makes them so important and interesting. You ready? Hopefully you are. 1.
How big are the Antennae Galaxies in light years?
The Antennae Galaxies sit in the Virgo Cluster and the estimated distance from the Earth is 45 million light years. Previously the distance was thought to be 65 million light years.
How are the Andromeda and Milky Way galaxies similar?
Scientists believe that when the Andromeda and Milky Way galaxies interact and collide that it will probably appear much like the Antennae galaxies at least at one point during the interaction. The two galaxies are going through each other at incredibly high speeds.
Which is the youngest example of a colliding galaxy?
The Antennae galaxy is believed to be one of the youngest and closest examples of a set of galaxies that are colliding. Almost half of the visual objects that are in the Antenna galaxy are images of young clusters that are home to tens of thousands of stars.
