What is it like inside a nebula?
Nebulae are pretty only when they are hundreds of light-years away.
They look thick and cloudy only because you see the structures of light-years in thickness.
Once you’re close to them, their light spreads out so much that you can’t see them.
You could fly your spaceship right into the nebula and never even know it..
What is a white star?
Definition of white star. 1 : a star of spectral type A or F having a moderate surface temperature and a white or yellowish color. 2a : an annual morning glory (Ipomoea lacunosa) of the southern U.S. with star-shaped leaves and small white or purplish flowers.
Is a nebula hot or cold?
As you know, nebulae are collections of gas and or dust in space. Some nebula which have star forming regions in them can become very hot ( 10,000 k), but without the stars, the nebula will be very cold.
What does a nebula look like to the human eye?
In the telescope, it is a green-to-gray cloudy patch. It’s just too dim for you to see in color. There’s not enough energy to excite the cells in your retina that are responsible for color vision. If your eyes were sensitive enough, you’d see it in shades of purple and red.
What causes a nebula to form?
Nebulae, which is the plural form (more than one) of nebula, form when gas, like hydrogen and helium, as well as molecules, particles, ions, and electrons are pulled together by gravity. Some of the gas and dust particles group together to create common regions that have similar densities.
What is a nebula made of?
The roots of the word come from Latin nebula, which means a “mist, vapor, fog, smoke, exhalation.” Nebulae are made up of dust, basic elements such as hydrogen and other ionized gases. They either form through clouds of cold interstellar gas and dust or through the aftermath of a supernova.
How long does it take to form a nebula?
roughly 14 billion yearsbasically Nebulae take roughly 14 billion years to form — at the least the ones that are formed right now do — there are probably tons of nebulae that are still in the ‘Star’ phase of their lives and are forming right now… even nebulae far away from here that have already formed but the light has yet to arrive here on …
Are nebulae dangerous?
There’s nothing especially dangerous about the nebula specifically, deep space will kill your crew in time, if their ship is damaged. They need to escape this nebula to get to somewhere they can do long-term repairs on their ship.
Is a nebula a dead star?
A nebula is a cloud of gas and dust in space. Some nebulae (more than one nebula) are regions where new stars are being formed, while others are the remains of dead or dying stars. Nebulae come in many different shapes and sizes.
What creates planetary nebula?
Planetary nebulae came to be understood as a final stage of stellar evolution. Spectroscopic observations show that all planetary nebulae are expanding. This led to the idea that planetary nebulae were caused by a star’s outer layers being thrown into space at the end of its life.
Is Earth in a nebula?
The planet Earth is not part of any particularly named Nebula . Earth is part of the Solar System which is part of our home galaxy, the so-called “Milky Way”, which is part of the so-called Local Group , a collection of more than 50 other galaxies in the “neighborhood” of our own galaxy.
Where are nebula found?
Where are nebulae? Nebulae exist in the space between the stars—also known as interstellar space. The closest known nebula to Earth is called the Helix Nebula. It is the remnant of a dying star—possibly one like the Sun.
