  • Blog Post: On the road: AAS January 2013 meeting — supernovae and dark energy

    It’s the end of the third full day, and my last, at the American Astronomical Society meeting. In addition to attending press conferences about exploding massive stars and cosmology, I spent time checking out some of the poster presentations and attending science sessions about imaging exoplanets...
  • Blog Post: On the road: January 2012 AAS meeting, Wednesday recap

    Even though the American Astronomical Society (AAS) meeting still has another day of research presentations and invited talks, today was the last day of press conferences — and the organizers made sure it was a good one. [caption image="/cfs-filesystemfile.ashx/__key/CommunityServer.Blogs...
  • Blog Post: Life as an astroimager

    Anthony Ayiomamitis was trying to image this stunning supernova remnant in Cygnus, CTB 80, which the Hubble Space Telescope captured in 1997. NASA and The Hubble Heritage Team (STScI/AURA) During the past week or so, I’ve received two e-mails from Athens, Greece, astroimager and longtime Astronomy contributor...

  • Blog Post: Are quirky supernovae “quark novae”?

    Three of the most luminous supernovae on record — 2006gy, 2005gj, and 2005ap — pose problems for theorists. For example, 2006gy’s peak luminosity reached 50 billion Suns. That’s 10 times brighter than the average type Ia supernova and 100 times brighter than a representative type II. And 2005ap was 2...
