14 wrz 2023 · Astronomers mapping the precise distances to tens of thousands of galaxies have found a curious cosmic structure. Galaxies by the thousands lie along a spherical shell that spans 1 billion light-years. The size alone is enough to challenge fundamental ideas about the universe.
24 sie 2007 · The void, which is nearly a billion light years across, is empty of both normal matter and dark matter. The finding challenges theories of large-scale structure formation in the universe.
11 sty 2024 · Astronomers Find Spark of Star Birth Across Billions of Years. These images represent a sample of galaxy clusters that are part of the largest and most complete study to learn what triggers stars to form in the universe’s biggest galaxies.
8 sie 2023 · Webb’s NIRCam also shows other notable details in the Sunrise Arc, which is the most highly magnified galaxy yet detected in the universe’s first billion years. Features include both young star-forming regions and older established star clusters as small as 10 light-years across.
8 paź 2019 · Using observations of galactic cosmic rays — a type of highly energetic particle — from NASA’s Voyager spacecraft scientists calculated the total pressure from particles in the outer region of the solar system, known as the heliosheath. At nearly 9 billion miles away, this region is hard to study.
The supercluster is about 1 billion light years away. An all-sky plot of the 60000 brightest galaxies shows how galaxies clump together into large supercluster formations. The positions of some of the major superclusters are marked although only the nearest superclusters are prominant.
23 lis 2022 · Imagine, even at this fast pace, it would still take 2,958 years to cover a distance of one light year, a testament to the vastness of space—approximately 5.88 trillion miles (9.46 trillion kilometers).
