Tucked away in the sub-basement of Pitt's Benedum Hall, past the racecar parts spilling into hallways, you'll find a giant machine that looks like a cross between a car garage and the entry port of a sci-fi spaceship. It's a state-of-the-art 3D printer for metal - the first Gefertec arc605 at any university in the U.S.

In Einstein's theory of general relativity, gravity arises when a massive object distorts the fabric of spacetime the way a ball sinks into a piece of stretched cloth. Solving Einstein's equations by using quantities that apply across all space and time coordinates could enable physicists to eventually find their 'white whale': a quantum theory of gravity.

Scientists at Queen Mary University of London have made two discoveries about the behaviour of 'supercritical matter' - matter at the critical point where the differences between liquids and gases seemingly disappear.
Previously, while the behaviour of matter at reasonably low temperature and pressure was well understood, the picture of matter at high temperature and pressure was blurred.

Rick LaBrode has worked at NASA for 37 years, but he says the American quest to return to the Moon is by far the crowning moment of his career.
LaBrode is the lead flight director for Artemis 1, set to take off later this month—the first time a capsule that can carry humans will be sent to the Moon since the last Apollo mission in 1972.
"This is more exciting than really anything I've ever been a part of," LaBrode told journalists at the US space agency's Mission Control Center in Houston, Texas.

NASA's 2023 annual Breakthrough, Innovative and Game-Changing (BIG) Idea Challenge asks university students to design a metal production pipeline on the Moon - from extracting metal from lunar minerals to creating structures and tools. The ability to extract metal and build needed infrastructure on the Moon advances the Artemis Program goal of a sustained human presence on the lunar surface.

Over the last 25 years, astronomers have found thousands of exoplanets around stars in our galaxy, but more than 99% of them orbit smaller stars - from red dwarfs to stars slightly more massive than our sun, which is considered an average-sized star.

Analyzing data from NASA's Hubble Space Telescope and several other observatories, astronomers have concluded that the bright red supergiant star Betelgeuse quite literally blew its top in 2019, losing a substantial part of its visible surface and producing a gigantic Surface Mass Ejection (SME). This is something never before seen in a normal star's behavior.
