Massive Object Detected Via Gravitational Puppetry

The universe we see doesn’t always reflect the universe that is out there. Luckily for us, a lot of dark details can’t stay hidden for long because their motion gives them away.  The Gaia spacecraft was launched in 2013 on a mission to measure the precise locations of every point and smudge of light visible to the craft's weird rectangular mirrors. With the ability to see motions across the sky that are...

Eta Carina gives up 260year Secret to Chandra

Credit: X-ray: NASA/SAO/GSFC/M. Corcoran et al.; Image Processing: L. Frattare, J. Major, N. Wolk (SAO/CXC) Astronomers kind of live to see weird weird objects. While likely always visible to humans, this southern hemisphere star transformed from kind of meh to the...

 Credit: Science Communication Lab for DESY Ultimately, our universe is far more diverse in its reality than humans tend to be in our theorizing. Over and over, we have found remarkable things just by turning a new instrument skyward. From the discovery of cold...

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...
