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 ...
This quiz/worksheet set can help you measure your knowledge of stellar nebula. See if you know what these are and what role they play in the universe as a whole. Quiz & Worksheet Goals In this quiz, you'll find out if you remember: The state of matter that most things in the uni...
Nebula play a key role in the life cycle of stars, both at their birth and death. Stars are born in dense clumps of gas, dust, and other material inside diffuse emission nebulae, also frequently referred to as "stellar nurseries". Hubble’s Pillars of Creation is in this category, as...
TheOrion Nebulais an emission nebula and star-forming region. It is the most active star-forming region in our Galaxy, and can easily be observed up-close with a small telescope. The Orion Nebula is a perfect example of a star-forming region or “stellar nursery”. Planetary Nebulae When ...
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....
One nebula, of a type known as a planetary nebula, is called the Boomerang Nebula and is the coldest place in the Universe. It's colder than the Cosmis Microwave Background, which is often regarded as the average temperature of space. And there's the famous Red Rectangle Nebula, whose sh...
The zone is also known as the circumstellar habitable zone. 2. The following picture is from NASA 3, which shows the Goldilocks Zone around Earth and an extrasolar planet known as Kepler 22b. As you can see from the image, both Mars and Earth are in the zone, but life as we know ...
ANebulais a giant mass ofcloudand dust that can be light-years across, such as the Snake Nebula, which is three light-years in diameter. They can be visible, although not seen clearly by the naked eye. There are five types, or to put it another way, classifications of Nebulas out ther...
I began to think of the new Kinder Building as a stellar nebula—the genesis of a new polestar for the U.S. art world. The museum contains numerous objects of fascination, from the prehistoric to the up-to-the-minute, but what I love most is the way the curators have put w...
The main sequence stage occurs after a stellar nebula collapses due to the force of gravity. As the nebula collapses, the internal temperature increases. When the core of the newly-formed protostar reaches a certain temperature, nuclear fusion starts. Nuclear fusion is a nuclear reaction that rele...
