Dark energy – which causes the universe to expand – can change
One of the great mysteries of the universe is how it expands. The phenomenon causing this expansion is known as dark energy — and recently scientists have begun to wonder…

JWST allowed astronomers to peer further into the past than any other infrared or optical telescope, seeing infrared light that was emitted from distant galaxies just 300 million years after…
We think of galaxies as ancient. Our own galaxy, Milky Wayformed 13.6 billion years ago, and James Webb Space Telescope allowed us to peek back at some of the first…
The search for the "missing matter" in the universe has failed so many times that some exotic proposals are taken more seriously than they once were. As Sherlock Holmes said,…
An international research team led by the Italian National Institute of Astrophysics (INAF) used the James Webb Space Telescope (JWST) to capture an extraordinary event in the distant universe: the…
A map of the line emission of hydrogen (in red and blue) and oxygen (in green) in the PJ308-21 system, shown after masking the light from the central quasar ("QSO").…
Artist's impression of the bright core region of a quasar, an active galaxy. The supermassive black hole at the center is surrounded by a bright disk of gas and dust.…
Based on their extensive involvement at CERN, the University of Rochester team recently achieved "incredibly precise" measurements of the electroweak mixing angle, a crucial component of the Standard Model of…
Researchers investigated three mysterious objects in the early universe. Shown here are their color images, composed of three NIRCam filter strips aboard the James Webb Space Telescope. They are remarkably…
Using the James Webb Space Telescope (JWST), astronomers have discovered star clusters in the "Cosmic Gems" arc that existed only 460 million years after the Big Bang. This marks the…
