To tell which stars are in the background, look at their colors. Stars whose light passes through the absorption nebula will be reddened — their blue light will be preferentially absorbed and ...

While you might have seen other images of nebulae radiating brilliant hues of greens, blues, and yellows, Lupus 3 is what’s known as a dark nebula, or an absorption nebula. These cosmic dust ...

Lupus 3 is a dark nebula, otherwise known as an absorption nebula. The dust particles that form this particular breed of cosmic cloud are so cold and dense that they effectively block and scatter ...

NASA explains in a new blog post that absorption nebula don't reflect or emit light like other nebula but instead block out any light that is coming from behind them. The agency continues to ...

Moving onward, we see a small reflection nebula (the small blue area containing two bright stars). Lastly, we have a dark absorption nebula, which contains so much opaque dust, the activity going ...

It isn't sucking in matter that comes too close to it. Instead, this is a dark absorption nebula that's located about 500 light-years away in the constellation Ophiuchus, known as Barnard 68 (the ...

The knots glow brightly due to absorption of ultraviolet light from the central stars. A pair of stars orbiting close together produced the nebula, also called PN G054.2-03.4. About 10,000 years ...

The observation of NGC 6357 is the first reported case of absorption of radio waves by an emission nebula ; it leads to an estimate of the electron temperature of the nebula based almost entirely ...
