Why has a giant ‘cold spot’ in the cosmic microwave background long puzzled astronomers?
The remaining light from the young universe has a major flaw, and we don’t know how to fix it. This is the cold spot. It’s too big and too cold. Astronomers aren’t sure what it is, but they mostly agree it’s worth investigating. cosmic microwave background (CMB) was created when our universe was only 380,000… Read More »
‘Stirring’ of energy waves on Earth may hold history of the universe
By measuring how energy waves move through the sky above Earth, scientists have created a way to delve into the 13.8 billion-year history of our universe, starting from “first light.” The team, led by Johns Hopkins University astrophysicists, used an array of microwave telescopes called the Cosmology Large Angular Scale Surveyor (CLASS) to map 75%… Read More »
James Webb Space Telescope detects dwarf galaxies powerful enough to reshape the entire early universe
Astronomers used the James Webb Space Telescope (JWST) and estimated this effect Albert Einstein More than 100 years ago, we discovered that small galaxies in the early universe had a massive impact that shaped the entire universe when it was less than 1 billion years old. The international team found that galaxies similar to the… Read More »
South Pole Telescope has a ‘treasure map’ to the secrets of dark matter
Ancient cosmic light, which evenly filled the universe about 400,000 years after the Big Bang, may serve as a treasure map guiding scientists to the secrets of dark matter. The Cosmic Microwave Background (CMB) refers to the first light that circulated freely in the universe. Its journey began after space had expanded and cooled enough… Read More »
Surprise gamma ray discovery may shed light on cosmic mystery
Astronomers have discovered an unexpected and unexplained feature outside our Milky Way galaxy that emits high-energy light called gamma rays. The team behind the discovery, including NASA and University of Maryland cosmologist Alexander Kashlinsky, found the gamma ray signal while searching through 13 years of data from NASA’s Fermi Telescope. “This is a completely accidental… Read More »
