Astronomers have uncovered a vast cloud of energetic particles—a "mini halo"—surrounding one of the most distant galaxy clusters ever observed, marking a major step forward in understanding the hidden ...

The early universe is perhaps one of the biggest mysteries of our time, and while we've come close to unraveling some of those earliest mysteries thanks to advancing tech like the James Webb Space ...

Somewhere between 50 to 1 billion years after the Big Bang, our universe experienced something known as Cosmic Dawn. This was the time period in which the very first stars, black holes, and galaxies ...

Scientists have found a remarkably small yet bright object from the early universe that doesn’t make sense in our existing models of how stars and galaxies formed, even our own Milky Way. That means ...

Astronomers may have uncovered the origins of the mysterious “little red dots,” some of the strangest galaxies seen in the early universe. These tiny but brilliant objects, discovered by the James ...

The James Webb Space Telescope found a surprisingly large galaxy, nicknamed "The Big Wheel," in the early universe. This galaxy formed much faster than current theories predict, challenging our ...

Findings from a new study into the cosmic "afterglow" may rewrite the history of the universe, according to researchers. This afterglow—the "cosmic microwave background" (CMB), the relic radiation ...

The oldest and most distant black hole known to scientists dates back 13.3 billion years ago, when our universe was still in its teething stage, according to findings published this month. The ...

IT IS ONE of the biggest mysteries in cosmology—and getting bigger all the time. Ever since Edwin Hubble, an American astronomer, published observations of distant galaxies in 1929, scientists have ...
