How are nebulae made

Best Answer

Nebulae are made when gas and dust form a large cloud. The gas collects in the middle, while the dust blocks out the light from the stars.

FAQ

Can we fly through a nebula?

It is theoretically possible to fly through a nebula, but the amount of energy required would be staggering. Even if a spacecraft could penetrate the nebula and bypass the harmful radiation and particles within, it would still face major obstacles on the other side – an alien universe entirely unknown and potentially hazardous.

How long does it take to form a nebula?

The time it takes to form a nebula depends on a number of factors, including the size and shape of the cloud, how much gas is present, and the temperature. In general, it can take anywhere from days to months.

How is a nebula formed NASA?

A nebula is formed when ionized gas and dust that are swirling around a central object break up. In the case of nebulas, this occurs as they are blasted off the surface of a star or when a star explodes.

What is the closest nebula to Earth?

The Andromeda Nebula is the closest open cluster to our galaxy, and lies about 2.5 million light years from Earth. Other nebulae that are closer to Earth include the Cat’s Eye Nebula and Orion’s Sword Nebulae.

Can we touch a nebula?

Yes, but only if you are a very brave extraterrestrial. Nebulas are simply gas and dust that have not yet had time to cool and form stars. If you touch one of these objects, the heat from your hands will cause it to heat up and eventually break apart into its component molecules.

Is the Milky Way a nebula?

Some scientists suggest that the Milky Way is, in fact, a nebula. The disagreement largely centers around the question of when and where the Milky Way began forming. Some believe that it developed gradually over thousands of years while others argue that it was born as a large clump of gas and stars less than 10 million years ago. Anecdotal evidence suggests that our galaxy likely contains billions of companions, some as small as stars and others as large as globular clusters. If this is true, then the Milky Way would indeed be a nebula

Is Earth in a nebula?

There is no scholarly consensus on this question. Some scientists believe that Earth is inside a nebula, while others contend it may be outside one.Wise Geek – Is Earth in a Nebula? The evidence for and against membership in a nebula is inconclusive and based largely on theory rather than direct observation.

How old are nebulae?

The oldest nebulae are around 12 billion years old, and the youngest are only around 3 billion years old.

Are black holes real NASA?

Black holes are a real possibility, however currently there is no way to access them and study them in detail.

Are stars born in nebulae?

Most stars are born in nebulae. In a Nebula, interstellar gas and dust is heated up from the emission of energy from young stars. The temperature and pressure cause the molecules to break down into smaller and smaller pieces until they form small helium nuclei (4 protons and 2 neutrons). This process of nuclear fusion creates heavier elements into Suns, Earths, and even white dwarfs.

How many nebulae are in the Milky Way galaxy?

There are about 100,000 nebulae in the Milky Way galaxy.

Can we see nebula with our eyes?

While we cannot see most nebulae with our eyes, there are a few exceptions. If you have very good eyeight and are looking at an area of the night sky that is free from bright city lights, you may be able to see some faint nebulae. Most nebulae, however, will only be visible using a telescope or binoculars.

What is inside nebula?

The interior of a nebula is filled with gas and dust. It’s not clear what is inside the nebula, but it might be stars, planets, or even alien life forms!

Is black hole in Milky Way?

Yes, black holes are found in the Milky Way. They are located at the centers of galaxies and around supermassive black holes.

How hot is a nebula?

A nebula is a huge cloud of gas and dust in space. It can be very hot, just like the sun!

How did the Earth begins?

The Earth began when a large body of molten rock and gas, called the mantle, slowly cools and contracts. This process produces intense pressure and heat that forces the solid material above it to squeeze together. Fracture lines form in this solid material as it tries to expand past these points of extreme pressure and heat. Over time, these fracture lines merge resulting in landmasses floating on the molten liquid rock below them (note: The outer core is still hot enough that it’s constantly boiling).
