Early Universe Clues Found Locally

A portion of the dwarf galaxy Wolf–Lundmark–Melotte (WLM) captured by the James Webb Space Telescope’s Near-Infrared Camera. The image demonstrates Webb’s remarkable ability to resolve faint stars outside the Milky Way. Color translation: 0.9-micron light is shown in blue, 1.5-micron in cyan, 2.5-micron in yellow, and 4.3-micron in red (filters F090W, F150W, F250M, and F430M). Credit: NASA, ESA, CSA, Kristen McQuinn (RU); Image Processing: Zolt G. Levay (STScI) There are two ways to go digging for ancient relics in our universe. You can use a telescope like the JWST to look at the light from...

New Luminous Fast Blue Optical Transient

Credit: NOIRLab/NSF/AURA/M. Garlick/M. Zamani To me it feels like our biggest unknowns are often part of the high-energy universe - those processes and objects rise to the highest temperatures and give off the bluest of light.  As an example, back in 2018, researchers...

Extra Light from Dark Matter in Pulsars… maybe?

Extra Light from Dark Matter in Pulsars… maybe?

credit: NASA/CXC/ASU/J. Hester et al., HST/ASU/J. Hester et al. We’ve said it before and we’ll say it again: the universe is an improv artist that likes to say “Yes, and”. I really wouldn’t be surprised if the effects we see are due to both a stuff we’ll collectively...

Janus: White Dwarf Edition

The results of science are often weirder than anything humans can imagine. As researchers, we dedicate our lives to taking data and knowing that whatever we may want to believe, we have to accept the reality of what our data shows us.  And sometimes the data is...
