What happens when a star runs out of hydrogen?
Eventually the core of the star runs out of hydrogen. When that happens, the star can no longer hold up against gravity. Its inner layers start to collapse, which squishes the core, increasing the pressure and temperature in the core of the star. At this point the star is called a red giant.
How long can a star live?
Generally, the more massive the star, the faster it burns up its fuel supply, and the shorter its life. The most massive stars can burn out and explode in a supernova after only a few million years of fusion. A star with a mass like the Sun, on the other hand, can continue fusing hydrogen for about 10 billion years.
What causes a dark nebula?
The darkness of the Horsehead is caused mostly by thick dust, although the lower part of the Horsehead’s neck casts a shadow to the left. Streams of gas leaving the nebula are funneled by a strong magnetic field. Bright spots in the Horsehead Nebula’s base are young stars just in the process of forming.
How many stars can a nebula produce?
700 stars
What is the largest nebula in our galaxy?
giant nebula NGC 3603
Are nebulas dangerous?
There’s nothing especially dangerous about the nebula specifically, deep space will kill your crew in time, if their ship is damaged.
What nebula is Earth in?
According to modern astronomers, the Orion Nebula is an enormous cloud of gas and dust, one of many in our Milky Way galaxy. It lies roughly 1,300 light-years from Earth.
How was Earth created?
Formation. When the solar system settled into its current layout about 4.5 billion years ago, Earth formed when gravity pulled swirling gas and dust in to become the third planet from the Sun. Like its fellow terrestrial planets, Earth has a central core, a rocky mantle and a solid crust.
Can you see the pillars of creation?
By photographing the Pillars of Creation in near-infrared light, the Hubble Telescope allows us to see the clouds of gas and peek at what’s happening inside. Made from cool interstellar hydrogen gas and dust, the 5-light-year-tall pillars are located within the Serpens constellation.
What comes after Pillars of Creation?
The Pillars of Creation is the seventh book in Terry Goodkind’s epic fantasy series The Sword of Truth….The Pillars of Creation.

10 light years
Who took the Pillars of Creation?
Hubble Space Telescope
Are the Pillars of Creation destroyed?
The Pillars of Creation won’t be around forever, but all signs point to them still being there today. They haven’t been destroyed, and as the light continues to arrive over the next thousands of years, we’ll see them shrink only slowly, likely for hundreds of thousands of years to come.
Where is the Hubble telescope now?
Where is the Hubble Space Telescope right now? The Hubble Space Telescope orbits 547 kilometres (340 miles) above Earth and travels 8km (5 miles) every second. Inclined 28.5 degrees to the equator, it orbits the Earth once every 97 minutes.
