By combining data from the James Webb and Hubble space telescopes, Nasa created an unprecedented image of a galaxy cluster
NASA's new pictures of Earth are reigniting conspiracy theories straight out of "Journey to the Center of the Earth." These are previously unreleased images of our blue marble planet, showing the ...
As in all real images from our Arm of the galaxy much is obscured by the Great Rift, dark dust clouds that span from Cygnus to Centaurus. In astronomy , the Great Rift (sometimes called the Dark Rift or less commonly the Dark River ) is a dark band caused by interstellar clouds of cosmic dust that significantly obscure ( extinguish ) the center ...
