Strange behavior in a huge cluster of merging galaxies could be explained if dark matter, the universe’s most mysterious stuff, can collide with itself. However, the most favored model of cosmology at the moment is the Cold Dark Matter (CDM) model – and it suggests that dark matter, which is effectively invisible because it does … Read more
An international team of astronomers has announced the detection of two of the earliest and most distant galaxies known. The light from both comes from just 300 million years after the Big Bang and it was only possible to observe them thanks to the power of the James Webb Space Telescope (JWST). The galaxies are … Read more
JWST recently caught three of the earliest galaxies in the universe as they were contracting from a giant, dark cloud of hydrogen gas. The three faint spots of red light in a recent set of JWST data traveled more than 13 billion light-years through space to reach the telescope’s mirrors. That ancient light provides a … Read more
Galaxies consist of various astronomical objects, including black holes, planets and stars. At the core of a galaxy lies a supermassive black hole (SMBH), one of the most powerful and dangerous entities in the universe. A puzzling question for scientists was whether SMBHs produced galaxies or whether galaxies formed SMBHs. Events in the early universe … Read more

Scientists have just identified it the formation processes of some of the universe’s earliest galaxies in the turbulent era of the Cosmic Dawn. JWST observations of the early Universe some 13.3 to 13.4 billion years ago – just a few hundred million years after the Big Bang – have revealed telltale signs that reservoirs of … Read more
Astronomers use the James Webb Space Telescope have discovered what they believe to be three of the earliest galaxies in our universe, actively forming when the cosmos was only 400 million to 600 million years old. In the JWST images, this galactic trio appears as faint red blobs feeding on nearby helium and hydrogen. For … Read more

Although this is how galaxies form according to theories and computer simulations, it had never been observed before.

Researchers analyzing data from NASA’s James Webb Space Telescope have identified three galaxies that may have been actively forming when the universe was just 400 to 600 million years old. Webb’s data shows that these galaxies are surrounded by gas that the researchers suspect is composed almost exclusively of hydrogen and helium, the earliest elements … Read more
A team of astronomers has managed to remotely calculate the speed of rotation of a supermassive black hole thanks to the object’s chance encounter with a star, which instantly destroyed it. How will time travel change Perry in Outer Range Season 2? All black holes have spin, which they develop through their interactions with other … Read more
