This stunning image from the Hubble Space Telescope captures a region called G35.2-0.7N, renowned as a hotbed for high-mass star formation. The Crab Nebula is the expanding remnant of a star's ...
ABSTRACT Recent analyses of nebular spectra have resulted in discrepant abundances from CNO forbidden and recombination lines. We consider independent methods of determining ion abundances for ...
These reflection and emission nebulae, along with other types of nebulae, make up some of the most interesting and varied objects in our local part of the universe to observe with a telescope.
A planetary nebula (PN, plural PNe), is a type of emission nebula consisting of an expanding, glowing shell of ionized gas ejected from red giant stars late in their lives. The term "planetary nebula" ...
The soft light from a nebula may also come from the ambient radiation released by the nebular cloud itself. This type of cosmic cloud is known as an emission nebula. One of the most famous is the ...
Nebulae are all but impossible to spot in the night sky, but you'd never know it. Through a telescope, they make the most jaw-dropping beauty shots. But what is a nebula in the first place?
