Don Pettit Proves Stars Can Be Tracked From ISS

Photo taken by Astronaut Don Pettit from ISS: Milky Way with Zodiacal light and Starlink satellites streaking by. Astronaut Don Pettit is, among many other things, an amateur astronomer. One of the most delightful moments of my life with getting to hear him talk to National Geographic photographer Babak Tavarshi about the challenges of trying to image the sky from the International space station and asking to brainstorm solutions. Well, it looks like that conversation, and many more that I assume have also taken place, allowed Don to figure out how to get past some of the issues he was...

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?

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...
