The NSF-DOE Vera C. Rubin Observatory, a major new scientific facility jointly funded by the US National Science Foundation ...

Looking up at the stars at night, it may not be obvious that the universe is constantly changing. But it is: Stars are dying; comets are flying; and supermassive black holes are growing ever more ...

Before light from distant stars can reach telescopes on Earth, it must travel through space, and its path is not always a straight one. Massive objects like the sun warp space around them. When light ...

A very quirky quark Physicist Christian Schwanenberger has been studying the top quark since 2004. “I arrived a Fermilab nine years after the discovery,” says Schwanenberger, a scientist at DESY and ...

Inside an ordinary-looking cupboard in an ordinary-looking office, scientists at CERN store a small glass vial filled with 10 grams of lead. But this is no ordinary metal. The lead in this vial is ...

In the late 1890s, physicist Max Planck proposed a set of units to simplify the expression of physics laws. Using just five constants in nature (including the speed of light and the gravitational ...

In 2017, Savannah Thais attended the NeurIPS machine-learning conference in Long Beach, California, hoping to learn about techniques she could use in her doctoral work on electron identification.

The best of both worlds Collider experiments crash beams of particles, pumped full of energy, into one another or into a target. In the crash, all of that energy can briefly convert into new particles ...

In the beginning, a spaceship called the Yggdrasil is sailing through the cosmos to find a new home for its long-term inhabitants. Suddenly, the ship is hit by a stray asteroid, damaging the hydrogen ...

At the start of the 20th century, physicists had a problem: The speed of light was always the speed of light. If you threw a baseball out of a train going 20 mph, it would travel the speed at which ...

In the wee hours of July 17, an old tree in the Swiss countryside let out a groan, then a crack. A moment later, about 35 miles away, CERN engineer Jose Antonio Ferreira Somoza heard his phone ding.

With enough time and magnifying power, a telescope can gather all the light it needs to create a pretty complete portrait of a single, distant galaxy. But some scientists are opting for a more ...
