What are the similarities between a Nebula and a Supernova?
Not much other than that they both emit light in large quantities.A nebula is a grouping of billions of stars, while a supernova is a single star exploding at a stage in its development.Comments: That meaning of "nebula" as a galaxy (or a star cluster within a galaxy) is a bit out of date now. Nowadays a nebula usually means a cloud of gas and dust. It doesn't usually emit much light.Actually there is a connection between a supernova and a nebula.Some of the stuff found in nebulae comes from supernova explosions.
Do scientists still explore the Milky Way Galaxy and find new things?
Most of the observation astronomers make are inside our Galaxy. Of course we still find new things. The Milky Way is a very complex and diverse collection of celestial objects. We still have much to learn!
What is significant about the Milky Way galaxy?
For several decades, astronomers believed that the Milky Way galaxy was a spiral galaxy similar to M31 in Andromeda. But recent observations indicate that the Milky Way may actually be a "barred spiral" galaxy.In either event, the Sun and our solar system are about 2/3 of the way out on one of the spiral arms, a very long way from the center of the Milky Way. Which is probably just as well, as recent research indicates that many galaxies including ours may have supermassive black holes at the center. So anywhere near the center of the galaxy would probably be a very nasty place to be!
Where in the universe is our solar system and milky way?
Milky Way: About 100,000 light-years in diameter Universe: Unknown, but the observable Universe has a diameter of about 92 billion light-years. Solar System: There are different definitions for the limits of the Solar System; if you include the Oort Cloud, you would have a diameter of about 4 light-years. That's a radius of about 2 light years, taking you about half way to the nearest star. With many other commonly used definitions, the "Solar System" is much smaller.
How much money did Galaxy Quest gross worldwide?
Galaxy Quest grossed $90,523,726 worldwide.
Are spiral nebula outside the Milky Way?
Yes, a spiral nebula is type of galaxy much like the Milky Way.
Is the universe in the milkyway?
..What..? The univere is EVERYTHING, including the milky way galaxy.
Is the Milky Way much smaller than the black hole?
No - The volume of the Milky Way galaxy is larger than the volume of its host black hole. The accumulated mass of the Milky Way galaxy is greater than the mass of its host black hole. The density of the Milky Way galaxy is much smaller than the density of its host black hole.
Is a galaxy bigger than a moon?
Yes, much bigger. There are many stars in our galaxy, thousands of millions of them. Everything you see in the night sky is in our galaxy, including the Moon, so the galaxy is much bigger.
Is the milky way bigger than the sun?
Yes, the Milky Way is much much larger than our Sun. The Sun is part of the Milky Way, and is one of over 200 billion stars in the Milky Way.
Is the Milky Way galaxy your solar system?
No. The Milky Way is much, much bigger than our Solar System - and it contains billions of solar systems.
Which is the largest a nebula a galaxy a neutron star a globular star or a nebulae?
Galaxies are by far the largest. Galaxies contain millions to trillions of stars, each orbiting the galaxy's centre of mass. Our own Milky Way is an example of a galaxy, of which our sun is just one of 200 to 400 billion other stars. The Milky Way is estimated to be in the region of 100,000 to 120,000 light years across. Nebulae (the plural of nebula) are gas regions where stars are often formed. They exist within galaxies and are therefore much smaller. The famous Orion Nebula is estimated to be 24 light years across, while the larger Carina Nebula is in the region of 100 light years across. Both exist within the Milky Way. A globular star, or globular cluster, is a cluster of stars. There are around 150 to 158 such clusters known to exist in the Milky Way, with perhaps 20 more yet to be discovered. A neutron star is a stellar remnant, the result of a supernova (exploding star). They are much smaller than the original star would have been, but are incredibly dense and often rotate very rapidly, emitting electromagnetic radiation as pulsars.
Is a galaxy bigger than a nebula?
Yes, a galaxy is typically much larger than a nebula. Galaxies are massive systems containing billions to trillions of stars, while nebulae are clouds of gas and dust in space that can range in size from a few light-years to hundreds of light-years across.
How much is the galaxy?
Our galaxy, The Milky Way, has a diameter of about 100,000 to 120,000 light years and contains more than 400 billion stars.
The Milky Way galaxy is much smaller than?
The Milky Way galaxy is much smaller than the largest known galaxy in the universe, IC 1101. IC 1101 is about 6 million light-years in diameter, whereas the Milky Way is approximately 100,000 light-years in diameter.
How did Edwin Hubble's discovery that the Andromeda galaxy was far away of our own galaxy contribute to astronomers' knowledge about the size of the universe?
Prior to Hubble's discovery scientists generally believed that our galaxy was the entire universe. Hubble found that the Andromeda galaxy was, then called the Andromeda Nebula, was not a part of our galaxy but a galaxy unto itself far beyond the edge of the Milky Way. This discovered demonstrated that the universe is much larger than scientists have believed.
Which is bigger the sun or the galaxy?
The sun is but one of several hundred billion stars within the Milky Way Galaxy. Thus the galaxy is much larger. The Milky Way is so vast that it takes light approximately 100,000 years to travel its diameter, and 1,000 years to travel its thickness. http://en.wikipedia.org/wiki/Milky_Way
