Planetary nebula: The Helix Nebula This is composed of expanding gas that was blown off by a star as it collapsed to a white dwarf. (Image credit: NASA, ESA, J. Hester, A. Loll (ASU)) Supernova remnant: The Crab Nebula Exactly as the name says, this is all that remains of a ...
A stellar nebula is a cloud of superheated gases and other elements formed by the explosive death of a massive star.Stellar nebulae emit brilliant waves of infrared light generated by dust particles within the cloud. The cosmic objects known as nebulae, from the Latin for cloud, serve as the ...
A nebula, named for the Greek word for ‘cloud,’is in fact an interstellar cloud of dust and gas.Like the clouds in the sky, nebulae come in interesting shapes like flowers, insects, animals or people.This is how many of them get their names.There are four main types of nebulae....
A planetary nebula is a phenomenon that occurs when a small to medium-sized star approaches the end of its life cycle. While very large stars end their lives in an explosion of light called asupernova, smaller stars fade out more gradually as gases and radiation exit their core. The first...
This is done either through the formation of a planetary nebula or a supernova. In this way, stars produce and distribute heavier elements such as carbon, nitrogen, and oxygen in the universe. The Sun is the closest star to Earth; however, many other stars are visible at night. One of ...
The term Planetary Nebula is one type of Nebulae (Not nebulas), which are large clouds of ice and dust that have been created in the aftermath of the death of a star. Although their name includes “planet”, they are nothing to do with planets. They do get their name from the mistaken...
of star that produced the explosion. With a Supernova Remnant, the star producing the explosion would be about eight or more times our son. Anything smaller would create a planetary nebula. Ref:Cornell. The image is of theCrab Nebula, which despite its name, is not inCancerbut is in...
The Orion Nebula is a perfect example of a star-forming region or “stellar nursery”. Planetary Nebulae When early astronomers observed these round, compact nebulae in the night sky – they thought that they must be planets. In reality, planetary nebulae have nothing to do with planets. ...
What is a Star? It's a cloudless night and you're sitting outside, looking up at twinkling lights in the dark sky above you. You wonder about those stars and what they're made of. People thousands of years ago wondered the same things, and now we have some pretty cool answers to ...
A 3D illustration of a neutron star in the nebula. (Image credit: Shutterstock) Neutron stars are the remnants of giant stars that died in a fiery explosion known as a supernova. After such an outburst, the cores of these former stars compact into an ultradense object with the mass of...
