What do nebulae really look like? Nebulae areastoundingly large accumulations of dust and gas, sometimes spanning tens to thousands of light-years across. Moreover, most of Hubble's nebulae images depict a saturated collection of colorful clouds. Is nebula A celestial object? An astronomical objec...

Planetary nebulae (PNe) are old- and intermediate-age\nstar remnants and their chemical abundances can be obtained up to 3-4 Mpc. H II\nregions, which are brighter and much easily detected, represent galaxies young\ncontent. PNe and H II regions share similar spectroscopic features and are\...
So the size of the universe was at stake.Finally in the 1920s we came up with a telescope that was strong enough to tell us something new here.When we used it to look at the spiral nebulae, we saw ...well, we were not absolutely sure, but it really looked like there were stars ...
Aurora is a natural light display in Earth's sky, primarily seen in high latitude regions, caused by solar winds disturbing the magnetosphere. Nebulae are vast clouds of gas and dust in space, often the birthplace of stars, visible as luminous patches.
Where do nebulae come from? The Short Answer: A nebula is agiant 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...
Despite its name,planetary nebulae isn't anything to do with planets. They get their name from the British astronomerWilliam Herschel, Sir, who, when he first saw a planetary nebula, thought it looked likeUranus. Planetary Nebulae are created when a star comes to the end of its life. When...
The fourth kind of nebulae are dark nebulae.A dark nebula is a cloud of gas and dust that is only visible because of bright nebulae and stars behind it.Like a shadow or a silhouette,they take their shape from the light we do not see.One of the most famous dark nebulae is the ...
What you will not see is the dim outer portions of the nebula. With moderate sized telescopes (6 to 10 inch reflectors) you will be able to discern the brighter portions of some nebulae. The Ring Nebula, M57, is a favorite. It will look like a small "smoke ring". I have never bee...
Faint stars and other celestial objects are visible and it is dark enough for astronomical observations. Astronomers may need to wait for truly dark skies for objects likegalaxiesandnebulaedepending on the amount of light pollution present.
