Which is the definition of a nebula?
Definition of nebula 1 : any of numerous clouds of gas or dust in interstellar space.
What are the 4 types of nebulae?
These are emission nebulae, reflection nebulae, dark nebulae, planetary nebulae, and supernova remnants. Emission and reflection nebulae tend to be fuzzy in appearance and lack any noticeable shape or structure. They are also known as diffuse nebulae.
Which statement best describes a nebula?
The Short Answer: A nebula is a giant cloud of dust and gas in space. Some nebulae (more than one nebula) come from the gas and dust thrown out by the explosion of a dying star, such as a supernova. Other nebulae are regions where new stars are beginning to form.
What nebula is Earth in?
The Orion Nebula, also known as Messier 42 (or M42 for short), is the nearest star-forming region to Earth, located approximately 1,350 light-years away and is about 2 million years old according to NASA Jet Propulsion Laboratory.
What are the 5 main types of nebulae?
There are five types of cloudy or nebulous objects in the sky: planetary nebulae, emission nebulae, reflection nebulae, dark nebulae and supernova remnants.
What is an example of a nebula?
The definition of a nebula is a cloud of gas and dust in outer space. A mass of dust in the sky that reflects light and appears as darkness in the sky may be an example of a nebula. (astronomy) A cloud in outer space consisting of gas or dust (e.g. a cloud formed after a star explodes).
Are black holes created by a nebula?
Gravity is a powerful force: it keeps the planets revolving in their orbits around the sun, and it was even responsible for forming the planets, as well as the sun, from nebulae. If a star is large enough — which is determined when it forms — gravity can turn it into a black hole.
What is the spectacular explosion called when a blue giant star dies?
A supernova (/ˌsuːpərˈnoʊvə/; pl. supernovae /-viː/ or supernovas; abbr. SN and SNe) is a powerful and luminous stellar explosion. This transient astronomical event occurs during the last evolutionary stages of a massive star or when a white dwarf is triggered into runaway nuclear fusion.
Could life exist in a nebula?
Possibly, but probably not. It is not known when life formed on Earth, but Earth was once part of a nebula, and it now has life. Most likely life got started on Earth after the solar nebula was essentially gone, but that is not known with certainty.
Why do eyes look like nebula?
Essentially we’re seeing a bubble of glowing gas in space. At the edge of the bubble has more gas in out line of sight, we see the nebula as a bright ring with a dimmer center.
What are the differences between nebulae and planetary nebulae?
A: A nebula refers to clouds of dust and gas that lie between stars, in so-called interstellar space. A planetary nebula is a special type of nebula made when the outer layers of an old, giant star are thrown off into space.
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.
