Astronomers Discover Distant Galaxies Driving an Ancient Cosmic Makeover of the Early Universe

An international team of astronomers has used the Keck Observatory on Maunakea to identify the most distant group of galaxies identified in the Universe to date. This trio of galaxies (called EGS77) are participating in a sweeping cosmic makeover called reionization. The reionization era dates back to a time when the universe was only 680 million years old (less than […]

Massive Filaments Fuel the Growth of Galaxies and Supermassive Black Holes

An international group of scientists has used observations from the Subaru and Keck telescopes on Maunakea to observe enormous filaments of gas in the early Universe, extending over more than 3 million light years. By focusing on a massive cluster of galaxies located about 12 billion light years away in the constellation of Aquarius, the scientists were able to create […]
