Galaxies

A galaxy. Ours is the milky way, which is a barrel galaxy.

Answer- I think they are actually called star clusters. Galaxies contain much more than just stars. They contain stellar remnants, dust and gas, planets, and many other astronomical features.

There's an impossible way to classify all the shapes of 100 billion galaxies in the universe.

• A globular cluster contains hundreds of thousands of stars
• An open cluster contain less than a few hundred stars.
• A galaxy contains billions of stars.

Galaxies that emit much more radiation (different types of radiation) than a typical galaxy. This actually happens in the galaxy's center, so it's more accurate to talk about an active galactic nucleus. The active galactic nucleus is believed to be caused by a black hole. From Wikipedia: " The radiation from AGN is believed to be a result of accretion of mass by a supermassive black hole at the centre of its host galaxy."

The coldest place in the entire universe, so far as we know, is laboratories where research into Bose-Einstein condensates are going on. Temperatures of 500 picokelvins have been reached.

Something in radiative equilibrium with the deepest of deep space would reach about 2.7 K, or 2,700,000,000,000 picokelvins, positively toasty by comparison.

Color. The type of star effects the color. Like temperature wise. Spiral galaxies are generally more blue than elliptical galaxies due to its stars. Size is another characteristic along with luminosity.

yes there is 20 light years away. it is called Gliese 581g. this planet has land and water and it has the perfect things to create life. This planet is the perfect distance away from its sun for water in liquid form not too hot or cold. There are 7 planets in this solar system but gliese 581g is the only planet identical to ours found by scientists in 2007. This planet had 2 moons and an oxygen atmosphere for life to have evolved. this planet is in our home galaxy the milky way and is the second possible life formed planet besides our own

Earth

can we go there?

N0,because no spacecraft could go there but maybe in the far future

There are several thousand background galaxies behind the PGC 54493 galaxy (with billions of stars, planets, and moons in each one; as well as asteroids and nebulae). Their light has taken 13 billion years to reach Earth.

Approximately 4.2 light-years.

What's a sun? Joking, No the sun isn't in the middle its inside Saturn.

The current galaxy classification is based on.

* The Hubble sequence is a morphological classification scheme for galaxies invented by Edwin Hubble in 1936 * The de Vaucouleurs system for classifying galaxies is a widely used extension to the Hubble sequence, first described by Gérard de Vaucouleurs in 1959. * The Yerkes (or Morgan) scheme uses the spectra of stars in the galaxy

elliptical galaxies

• it take 1 zillion..........

Yes. The constellations we see, in fact all star visible from earth make up just a small part of one galaxy. A constellation may have a handful of stars while a Galaxy has billions if not hundreds of billions.

i think the dwarft

The average number of stars in a giant galaxy since it contains trillions of stars is 10 trillion.

Superclusters are very large groupings of smaller galactic clusters. Superclusters are the largest known structures in the Universe, and since they are not gravitationally bound, they partake in the Hubble expansion. The Milky Way Galaxy is located in the Local Group, which in turn is located in the Virgo Supercluster.

The Andromeda Galaxy (M31 galaxy).

According to wiki:

It is extremely difficult to define the age at which the Milky Way formed, but the age of the oldest star in the Galaxy yet discovered is estimated to be about 13.2 billion years, nearly as old as the Universe itself. This estimate is based on research by a team of astronomers in 2004 using the UV-Visual Echelle Spectrograph of the Very Large Telescope to measure, for the first time, the beryllium content of two stars in globular cluster NGC 6397. From this research, the elapsed time between the rise of the first generation of stars in the entire Galaxy and the first generation of stars in the cluster was deduced to be 200 million to 300 million years. By including the estimated age of the stars in the globular cluster (13.4 ± 0.8 billion years), they estimated the age of the oldest stars in the Milky Way at 13.6 ± 0.8 billion years. Based upon this emerging science, the Galactic thin disk is estimated to have been formed between 6.5 and 10.1 billion years ago.
