Galaxies

The Milky Way galaxy. Why should it be any different??

The Andromeda galaxy is 2.5 million light years away, meaning that it takes 2.5 millions years to get here traveling at the speed of light.

About 70% hydrogen, 28% helium, and 2% "other elements". As time goes on, the nuclear reactions in the Sun's core are fusing hydrogen into helium, and releasing vast amounts of energy.

In about 4 billion years (or so), the Sun's hydrogen reserves will be about half-gone. at that time, the Sun will heat up and begin to fuse helium into carbon and other heavy elements. The Sun will then expand into a red giant, and consume the inner planets.

venus (in terms of distance from the sun).

In terms of distance from the earth, it is Mars

In terms of size, it is Saturn.

The COSMOS 781155 galaxy (one of the galaxies in the COSMOS survey) is a spiral galaxy 7000 million light-years (redshift of 0.83) from Earth in the Sextans constellation, and is 120,000 light-years in diameter (1.2 times larger than the Milky Way), and contains about 200 billion stars (200 percent of the Milky Way's stars).

3C 153 is a Seyfert galaxy located in the constellation Auriga.

You can get into a parallel universe through wormholes which are located in the middle of blackholes. However it would take a space shuttle as BIG AS JUPITER to get near the blackhole without splitting into membrains. It would also take negative matter to keep the gate open FOR THAT LONG

Just like the Sun and the Moon, stars appear to move towards the west. The reason is that Earth rotates in the opposite direction - towards the east.

Wind speeds on Uranus range from 0 miles per hour at the poles to 240 miles per hour near the equator. Uranus is frozen therefore calm

parallax :)

they are types of orbits of the artificial satellites:-

Low earth orbit (LEO): about 160 Km to 640 Km above the earth, so the delay is very small and the losses is small too.

Medium Earth orbit (MEO): 1600 to 4200 km above the earth, and uses for navigation communications like GPS.

Geostationary orbit (GEO): about 36000 Km above the equator, the delay and losses are greater, but the advantages is more coverage (it covers 40% of the earth) and there no nedd to track the satellite, so the earth terminal is cheaper, but the GEO is more expensive than MEO and LEO. GEO uses for Satellite TV Broadcasting.

sombrero galaxy is (also known as M104 or NGC 4594) located in the constellation virgo is 11 to 13 billion years old. it is 28 million light years away from us .

Yes they are. Our sun is a very ordinary, unspectacular by galactic standards,second-generation star. we just happen to call it "The Sun" although we could have called it "The Kloppst" if we wanted to.

Precisely because they are rounded, like a globe or sphere.

The sky that we look up to is the universe itself. You see stars, you see the sun, the moon, some near planets. Asking "is the sky bigger than the galaxy?" makes no sense as a question. You can even see the Milky Way galaxy in the sky on a clear night sometimes. I would say the sky is the galaxy, in a way... The sky is space. We see beyond Earth when we look up to it at night.

However our field of view is definitely smaller than a galaxy, we can't see all around the outside of Earth from a single position. In this sense, a galaxy is bigger than the sky. But as I said, the question itself doesn't really make much sense.

there is no actual arrangment. it's random. not in any form or pattern just randomly there.

Hubble devised subcategorization for spiral galaxies first based on whether the galaxy exhibited a bar and then how well the spiral arms were defined. The classes are designated as Sa, Sb, and SC with the Sa class being the most tightly wound. A capital B designation after the S indicates the presence of a bar as well.

7 if you count the reticulum.

Spiral galaxy has 3 basic components to its visible matter: the disk, the halo, and the nucleus or central bulge.

Maybe life on planets far far away!

You can't. Don't try, it beats me why you would.

Andromeda is a spiral galaxy, similar to our own.

it use to be a map to know which way is west or north or whatever
