This means that galaxies had to be closer to each other in the past. In 1964, Wilson and Penzias discovered the cosmic background radiation, which is a like a fossil of radiation emitted during the beginning of the universe, when it was hot and dense. The cosmic background radiation is observable everywhere in the universe. The composition of the universe - that is, the the number of atoms of different elements - is consistent with the Big Bang Theory. So far, this theory is the only one that can explain why we observe an abundance of primordial elements in the universe.

Many exoplanets orbit older red dwarf stars, which are dimmer and cooler than our sun. The sheer scale of the universe strongly suggests Earth isn't its only life-hosting planet. But do distant worlds harbor the types of advanced spacefaring civilizations depicted in science fiction, or just far simpler microbes?

Astronomers Have Completed the Largest Map of Space. The intricate, 5.6 trillion-pixel map covers approximately 75 percent of the sky and includes about 4 billion celestial objects. The new DESI map contains some of the highest resolution images of galaxies, like this one in the constellation Leo over 35 million light years from earth. The driving force behind our universe's accelerated expansion remains one of the greatest mysteries in astronomy. While this force, which scientists refer to as dark energy, pervades our universe, we know almost nothing about it.

NGC 3938 is a face-on spiral galaxy whose orientation gives us an unobstructed view of its disk. X-ray emissions from Chandra (magenta) detail energetic X-ray binaries and supernova remnants scattered across dust lanes in an optical image (white, blue and gold) from Adam Block with Mt. Face-on orientations are important for galactic studies because they provide the most unobstructed views of a galaxy's stars and gas.
