The Math of Leap Days
The Bad Astronomer writes "We have leap days every four years because the Earth's day and year don't divide evenly. But there's more to it than that... a lot more. A year isn't exactly 365.25 days long, and that leads to needing more complicated math and rules for when we do and don't have a leap year. If you've ever wanted to see that math laid out, now's your chance, and it only comes along every four years. Except every hundred years. Except every four hundred years." -
'Amateur' Astronomer Snaps Pic of Planet-Forming Disk
The Bad Astronomer writes "Rolf Olsen, an 'amateur' astronomer in New Zealand, took an amazing photo of a disk of material around the star Beta Pictoris, the first time this has been seen outside of professional observatories. Incredibly, he snagged it with just a 25 cm (10") telescope! A comparison with an earlier pic from a much larger observatory indicates he nailed it, making this a milestone for amateur astronomy." -
FTL Neutrinos Explained... Maybe
The Bad Astronomer writes "A new paper, recently posted on the arXiv physics preprint server, claims to have explained the faster-than-light neutrino experiment from last month. The author claims the motion of the GPS satellite introduces a relativistic dilation that accounts for the now-infamous 60 ns discrepancy in neutrino flight time. However, I'm not so sure; the original experimenters claimed to have accounted for relativistic effects. I don't think we've seen the end of this just yet." -
Astronomers Find Planets Around Weird Binary Star
The Bad Astronomer writes "Exoplanets orbiting binary stars have been discovered before, but NN Serpentis is a weird system even in that category. One star is a red dwarf in an incredibly tight orbit around a white dwarf. The white dwarf used to be a star like the Sun but became a red giant as it died, engulfing the red dwarf. Now the two orbit each other almost as closely as the Moon orbits the Earth. Explaining how the two newly detected exoplanets survived such an event is very difficult, and astronomers think they may have actually formed from the material expelled by the star as it died." -
Record-Breaking Galaxy Found In Deep Hubble Image
The Bad Astronomer writes "Astronomers using Hubble Space Telescope have found a galaxy at the very edge of the Universe: the light from this far-flung object has been traveling a whopping 13.1 billion years to get here! The galaxy appears as a non-descript dot in the infrared Hubble Ultra Deep Field taken using the Wide Field Camera 3, but a spectrum taken using a ground-based telescope confirms that we're seeing this object as it was a mere 600 million years after the Big Bang itself." -
Want a Science Degree In Creationism?
The Bad Astronomer writes "In Texas, a state legislator wants the ironically-named Institute for Creation Research to be able to grant a Masters degree in science. In fact, the bill submitted to the Texas congress would make it legal for any private group calling themselves educational to be able to grant advanced degrees in science. So, now's your chance: that lack of a PhD in Astrology and Alchemy won't hold you back any longer." The Institute for Creation Research made a similar request to the Texas Higher Education Coordinating Board last year, but were shot down. -
Illinois Declares Pluto a Planet
The Bad Astronomer writes "The legislators in Illinois, always on the lookout for more places to find voters, have passed a resolution declaring Pluto is a planet. I'm not sure what else can be said here, except that — besides overstepping their jurisdiction just a wee bit — they make a couple of scientific howlers in the resolution itself."
