After Euclid blasts off, it will travel to a spot called Lagrange point 2, about 1.5 million kilometers from Earth, where the telescope will have a clear view of deep space while being able to communicate with astronomers and enjoy…

But the word “most” is important. The ACT team’s findings agree with studies of the CMB made with instruments like the European Space Agency’s Planck telescope, which together cover the first 8 billion years of the universe’s life. But…

It’s a radical view of quantum behavior that many physicists take seriously. “I consider it completely real,” said Richard MacKenzie, a physicist at the University of Montreal.But how can an infinite number of curving paths add up to a…

Rohan Naidu was sitting at home with his girlfriend when he found the galaxy that nearly broke cosmology. As his algorithm dug through early images from the James Webb Space Telescope (JWST) late one night in July, Naidu shot to…

First second, The Big Bang is the most widely accepted theory in the scientific community to explain ... the birth of the universe. By applying known laws of physics and taking advantage of the huge progress made…

A giant cosmic web of invisible gas weaves throughout the universe, providing the scaffolding out of which galaxies were born. Before now, however, the only way to see this web was indirectly, in a few select regions where a bright…

For the first time, astronomers have obtained large-scale images of the cosmic web — the incredibly ancient scaffolding of dark matter and hydrogen gas out of which galaxies in the Universe were formed. This material is so far…

For as long as there has been a Universe, space has been expanding. It winked into existence roughly 13.8 billion years ago, and has been puffing up ever since, like a giant cosmic balloon.  The current rate of this expansion is called…

The hot and cold spots from the hemispheres of the sky, as they appear in the CMB. This encodes a ... tremendous amount of information about the early Universe. We expect both hemispheres to have the same average temperature and…
