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).

You can use a telescope like the JWST to look at the light from...

Finding the Source of Low-Hydrogen Supernovae

Visualization of a binary star experiencing mass transfer. Credit: Ylva Götberg One factor upping the difficulty of understanding our universe is… the complexity of our universe. It sometimes feels like every time we think we’re getting a handle on how things work,...

500,000 Stars, with More Born Regularly

Credit: NASA, ESA, CSA, STScI, and S. Crowe (University of Virginia) Our Solar System lives in a nice suburb of the Milky Way. Sitting about 25,000 light years from the galactic center, we’re in a good place to view what’s happening in the core district, but far...

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...
