You may have seen one of these astronomical scale picture sequences, where you go from the Earth to Jupiter to the Sun, then the Sun to Sirius – and all the way up to the biggest star we know of VY Canis Majoris. However, most of the stars at the big end of the scale are at ...
which is fairly close to a googol.This is a very rough estimate, but it’s easy to see how the number could become so large. After each chess player makes their first move, there are400 potential board setups. After each player has made two moves, there are 197...

French astronomerCharles Messier(1730–1817) composed a database of objects known at the time as "nebulae," which included 103 objects at its final publication, though additional objects were added based on his personal notes. Many of these objects are often listed with their catalog name, such...

Therefore, these spiral nebulae were indeed other galaxies outside our own. There are still many mysteries surrounding galaxy formation, but on the next page we'll explain some of the best theories about it. Light-years Away Galaxies are far apart. The Andromeda galaxy, which is also ...
Some nebulae, such as the Horsehead, are a real challenge to find and observe. Nebulae are best viewed under low magnification, and rich-field telescopes can provide good views. Large aperture telescopes can gather enough light to produce bright images, and light pollution filters may help you ...
Since the launch of NASA's James Webb Space Telescope (JWST), the agency has made several profound discoveries and put out some of the most stunning images of galaxies and nebulae that exist. In 2024, the telescope again pushed the boundaries of our understanding of the universe by identifying...
