Blood Moons

The Moon blood red because it's completely inside the Earth's shadow.
August 21, 2015

Total Lunar Eclipse April 15th 2014, as seen from the Mount Lemmon SkyCenter. SkyCenter.Arizona.edu In the early hours of September 28th the moon will plunge into the Earth’s shadow and turn blood red. It’s a perfectly normal event, produced by the combined orbits of the earth and moon and the effect of the Earth’s atmosphere bending the sunlight like a lens, but it’s dramatic and spooky, and if you didn’t…

August 9, 2015

The Perseid meteor shower is already here, and it will reach its peak on August 12th as the Earth passes through the dust left by comet.

Venus and Jupiter and a different telescope, Izaña, Tenerife
July 21, 2015

  Since I got there early, I got a chance to try to photograph the nearest star – our Sun, through a small telescope with a filter which lets through a wavelength called H? (pronounced H alpha). It was tricky. I’m pretty short sighted, and I can’t see well with my glasses squdged up against the viewfinder. For normal stargazing, I take my glasses off and refocus the telescope, but…

Pluto and Google Deep Dream

  Deep Dream is all over the internet lately, but for those of you who heaven’t come across it, Google have invented an ‘artificial neural network’ which finds patterns in images, and then matches them with other pictures stored in its memory. The result is seriously weird. I recently learned that some people suffer from a phobia of objects with irregular patterns of holes (Trypophobia) and they find some Deep…
