A nebula is a cloud of dust and gas, usually tens to hundreds of light years across. ... Nebulae are one of the many things thatgalaxiesare made of, along with stars, black holes, cosmic dust, dark matter and much more. Why do nebulae glow? Within this type of nebula,a star energi...
Where and how do stars form? Where do stars come from? Why aren't planets on the planisphere? Why is the distance to planetary nebulae important? Why is it important to research planetary nebulae? What gives a star its color? Why is light pollution bad for astronomers? Why are there come...
Electron energy transitions and ionization are the processes by which so-calledemission nebulaein space glow. Emission nebulae are oftenstar-forming regions, and are being ionized by the hard ultraviolet light from the young, massive starsborn within them. Radioactive decay Not all atoms are stable...

In the final episode ofTNG(“All Good Things…”, S07E25 & 26), the cosmic entityQtellsCaptain Picard, “That is the exploration that awaits you. Not mapping stars and studying nebulae, but charting the unknown possibilities of existence.” This is sometimes mentioned as having initially bee...

whole galaxy. Supernovae leave their mark on the skies as nebulae, clouds of solar debris that make for many of the most iconic astronomical images ever captured. Supernovae can give birth to black holes and neutron stars, and their light can be observed from thousands of light years away...
Early in the 15 century In the middle of the century, the German Archbishop Nicholas has speculated that the stars in the firmament of night are all very far away Yang。 In the 1584, the Italians Bruno made it clear that the universe was infinite, that the stars were far away from the...
As well as finding new clusters, the Gaia data are proving useful for checking out the reality of previously reported associations of stars. "Using Gaia data I can see stars that share the same motion. So I can confirm which ones form real open clusters," says Andrés E. Piatti, Consejo...
