    My fellows of Club d'Astronomie Lyon-Ampère enjoying the starry sky of Observatoire de Haute-Provence (southeast France) during the night of Apr. 06, 2014. The bright source of light that cast shadows is the Moon, disturbingly bright on that night.

      This time-lapse video, taken on the night from 23rd to 24th of May 2010, shows one full night from before sunset to shortly before sunrise. If was taken just outside the WIYN telescope at Kitt Peak National Observatory, 50 miles west of Tucson, AZ. Viewing direction is to the north east, facing the mighty 4m Mayall telescope and a range of smaller telescope along the mountain ridge. The flickering at the beginning is caused by changes in the exposure time by a factor of ~200 000 to compensate for the decreasing sky brightness as the night sets in. The reason why it does not get really dark is the nearly full moon that significantly lights up the night sky. Once the moon has set about 2 hours before sunrise, the Milky Way becomes more prominent, but so does the light pollution from Tucson and its surroundings (to the right of the 4m) and Phoenix (to the left, thanks to Jerry Scott for pointing this out). Although Tucson is at only half the distance to Phoenix, due to its regulations Tucson causes by far less light pollution. Astronomical targets to look out for is the North or Pole star in the top left. It can be spotted easily as it's the only star that is not moving as time goes by, and so is the only real fix-star in the sky. In the second half of the night you can also see the Andromeda Galaxy, a galaxy very much like our own Milky Way at a distance of 2.5 million light years, as fuzzy, elongated object near the right border. Technical info: All ~ 1000 frames were taken 35 seconds apart with a Nikon D300 at 18mm and exposed for 30 seconds each.

        I've been lucky enough to spend the last few nights shooting with Leonid Tishkov for his Private Moon series of images. This timelapse was taken with a GoPro on top of the CSX building in Washington DC. Just one of the great opportunities provided by the Corcoran College of Art + Design New Media Photojournalism program.

        • The Eagle simulations: temperature of cosmic gas

          Volume rendering of a simulation from the Eagle project (home.strw.leidenuniv.nl/~crain/?page_id=2). The intensity corresponds to the density of cosmic gas, whilst colour encodes its temperature. Red roughly corresponds to 100,000 degrees Kelvin (considered 'warm' by astronomers), whilst white corresponds to 10-100 million degrees Kelvin. Gas is heated to such high temperatures by gravitational accretion shocks, and the injection of thermal energy by feedback from supernovae and black holes. The simulation volume is 25 cMpc across, with periodic boundary conditions, and was evolved with a version of the GADGET-3 TreePM-SPH code adapted specifically for Eagle. The simulation was run and visualised on the COSMA-5 supercomputer at Durham University (UK), by the EAGLE team. The visualisation was created by Rob Crain (Leiden Observatory, NL) and Jim Geach (Herts University, UK) using their Typhoon toolkit.

            We got very lucky at Ellis Beach near Palm Cove in the tropical North Queensland (Australia) in the morning of November 14th, 2012. Half a n hour before the total solar eclipse the Sun was well hidden behind a stubborn cloud, which did not seem to move anywhere. However, just before the totality phase the cloud moved and the Sun cleared, just in time for us to witness the most thrilling astronomical event – the total solar eclipse. Thanks to Promote DSLR controllers ( http://www.promotesystems.com ) I was able to enjoy the visual show whilst three cameras clicked through the pre-programmed eclipse sequences. Many thanks to James McHugh (http://www.deepspaceplace.com) for the excellent high-resolution footage of the second and third contacts, and partial phases of the eclipse!
