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...
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 type of nebulae formation is lit from within? What is the Andromeda Galaxy made of? What are planetary nebula made of? What is the Whirlpool Galaxy? What is the closest galaxy to the Milky Way? What is a quasar in astronomy? What galaxy do we live in? What is the edge of the...
These 4 nebulaeshould be quite bright, but I didn't see a hint of a misty cloud/nebula. Can someone tell me what I'm doing wrong? (Using a 8 inch dob at bortle 3) I can see the Orion nebula with ease. But I can't see other(!) nebulae - also not when totally dark adapted....

Male student: Well, I mean it assumed that the nebulae are not what they look like at first sight.The first theory assumed that, right? Professor: OK. And now tell me this which one would have seemed more likely at the time?
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.
It was only with the work of Hubble using Leavitt’s law to measure distances to Magellanic clouds and “spiral nebulae” (that we now know to be other galaxies), building on earlier work of Leavitt and Hertzsprung, that it was conclusively established that these clouds and nebulae in fact ...
