Dying Stars’ Final Artwork

One of the justifications for building the Hubble Space Telescope was to finally get a detailed enough view  of the fuzzy blobs we call planetary nebulae that we could finally understand what is going on. Turns out, for some of the nebulae, we actually needed something even better than HST - and that “better than” is the JWST.  First catalogued in 1790 by William Herschel, NGC 1514 is a binary star system surrounded by a glowy blob of stuff. One of the stars is actually a stellar remnant - a hot white dwarf that has shed its atmosphere and stopped undergoing nuclear reactions in...

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...

Extra Light from Dark Matter in Pulsars… maybe?

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...
