Galaxies
Galaxies are large systems of stars and interstellar matter, and they contain billions of stars. Our own galaxy, the Milky Way, has 200 to 400 billion stars, and there are over one billion known galaxies. Questions that have to do with galaxies in general and specific galaxies are perfect for this category!

Why is the sun important to every single person in the universe?
The sun helps plants grow , which helps us live and breathe.
The sun keeps us from getting to cold or become frozen.
The sun provides virtually limitless energy for Earth. Without the sun, plants could not photosynthesize and produce food, so everything would die out. All life starts at the sun.
Where does the word star in the sky come from?
The word star comes from the Greek word "ἀστήρ" Aster meaning Star.
The GN-z11 galaxy is an irregular galaxy 13,400 million light-years (redshift of 11) from Earth in the Ursa Major constellation, and is 4000 light-years (25 times smaller than the Milky Way) in diameter, and contains about 1 billion stars (1 percent of the Milky Way's stars).
Well considering stars die and are born all the time, the number would change all the time.
However, at the current estimate of 300 billion stars. At one a second a star, it would take about 9,500 years.
- A Galaxy Group: Is the smallest grouping and usually contains less than 50 galaxies.
- A Galaxy Cluster: Is larger than a group and usually contains between 50 to 1,000 galaxies.
- A Supercluster: Is the largest collection of galaxies and will contain many groups and clusters.
I think you mean group of galaxies. A group of galaxies is groups and clusters are the largest known gravitationally bound objects to have arisen thus far in the process of cosmic structure formation. They form the densest part of the large scale structure of the universe.
Who were the cast members of Galaxy Quest?
The Galaxy Quest movie cast members were Tim Allen who had played Peter Quincy Taggart, Sigourney Weaver who was Gwen DeMarco, Alan Rickman who was Alexander Dane, Tony Shalhoub who was Fred Kwan, Sam Rockwell who is Guy Fleegman, Daryl Mitchell who had played Tommy Webber, Enrico Colantoni who was Mathesar, Robin Sachs had played Roth'h'ar Sarris, Jed Rees had played Teb, Justin Long is Brandon, Missi Pyle who had played Laliari, Patrick Breen who was Quellek, Jeremy Howard who was Kyle, Samuel Loyd who was Neru, Rainn Wilson who had played Lahnk, J. P. Manoux who was an excited alien, Dian Bachar who had played a nervous tech and Heidi Swedberg who was Brandon's Mother.
How cold is the coldest place in the milky way?
The Milky Way is not a uniform object; different parts have different temperatures. In outer space, the temperature can go down to a few Kelvin (that is, almost absolute zero); in the center of some stars, the temperature can be a hundred million Kelvin, or even more. (Note: At temperatures of millions of degrees, Kelvin is the same as as Celsius, for practical purposes.)
What is the actual SIZE of Antares?
antares is much bigger than the sun, it is like a basketball comparing to a dot of rice
gaseous state.
Stars can be as close as a few million kilometers to as far as trillions and trillions of kilometers.
There is no real answer as distance relies on the objects in question and with trillions of objects to compare against, the answers would be of a magnitude far greater than the human brain could comprehend.
What are the 10 neighboring galaxys?
Look up "Local Group", on the Wikipedia for example. The Local Group includes the galaxies of our "immediate neighborhood" (a few million light-years distance at most!). The Local Group has much more than 10 galaxies, though.
What galaxy can people in the southern hemisphere see?
Our home Galaxy is the Milky way Galaxy.
It is in the form of a disk of stars with a blob of stars in the centre.
Our Solar system is near the junction of blob and disk, and the Southern Hemisphere looks towards the blob, which appears as a great glittering band across the night sky.
Who in the heck is Jackson galaxy?
The 'Cat Daddy' and host of the show 'My Cat From Hell' on Animal Planet. He is a genuine, kind and very humble person who believes in what he does with every part of his being.
Where is Sirius in the milky way galaxy?
Find Orion's Belt, and follow its line of stars down to the left and you will find Sirius. It is unmistakeable. It is easily visible in the winter but not summer.
Altenatively, look for the brightest thing other than the moon, and you've found it.
What is the typical age for a globular cluster associated with the milky way?
10-12 billion years old.
According to Hubbell's law more rapidly moving galaxies are now?
The law states that the galaxy's that are further away from us are moving faster.
How far is the NGC 6166 from Earth?
It is about 490 million light years away. A light year is a measure of distance, based on light travelling about 9.4 trillion kilometres in a year or about 5.9 trillion miles in a year.
By sending a probe to other planets we get amazing pictures how what they look like close up.
Other sensors on the probe can find out about the magnetic field and the surface temperature, and chemicals in the atmosphere, and find out details of the moons and rings of the outer planets.
Is there life in large magellanic cloud galaxy?
It is not currently known whether there is ANY life, ANYWHERE outside of planet Earth.
