James Webb Telescope glimpses possible first dark stars

Three dark stars nominated by JWST

image: These three objects (JADES-GS-z13-0, JADES-GS-z12-0 and JADES-GS-z11-0) were originally identified as galaxies in December 2022 by the JWST Advanced Deep Extragalactic Survey (JADES). Now, a team including Katherine Freese of the University of Texas at Austin speculates that they may actually be dark stars, theoretical objects much larger and brighter than our sun, powered … Read more

Cosmic paradigm shift: New research doubles age of universes to 26.7 billion years

Vast universe concept art

A new study suggests that the universe may be 26.7 billion years old, nearly double the widely accepted age of 13.7 billion years. The new model, which incorporates Zwicky’s tired light theory and Dirac’s evolving coupling constants, could explain the existence of small mature galaxies that formed just 300 million years after the Big Bang … Read more

Fermilab-led microelectronics codesign team works to develop a state-of-the-art particle detector

Particle accelerators and detectors are the workhorses of researchers plumbing the depths of the quantum realm. Each update gives scientists more opportunities to study the building blocks of our universe. Now, a unique collaboration of researchers, led by research engineer Davide Braga of the US Department of Energy’s Fermi National Accelerator Laboratory, is designing and … Read more

Female physicists are not represented in the media and this lack of representation hurts the field of physics

A young woman with folded hands standing in front of a large plant and wearing a skirt, blouse and hat.

Christopher Nolan Oppenheimer’s highly anticipated film, to be released July 21, 2023, depicts J. Robert Oppenheimer and his role in the development of the atomic bomb. But while the Manhattan Project wouldn’t have been possible without the work of many expert female scientists, the only women seen in the film’s trailer are hanging out the … Read more
