Amazing Video Timelapse Of Big Telescopes At Work In Chile

by Elizabeth Howell on September 2, 2014

What’s it like to spend a night at a huge telescope observatory? Jordi Busque recorded a brilliant timelapse of the Very Large Telescope (VLT) and the Atacama Large Millimeter/submillimeter Array (ALMA). What makes this video unique is not only the exotic location in Chile, but the use of sound in the area rather than music.

It’s an engaging thought experiment.

What if Earth had multiple moons?  Our world has one large natural satellite, just over a quarter the diameter, 1/50th the volume, and less than 1/80th the mass of our fair world. In fact, the Earth-Moon system has sometimes been referred to as a “binary planet,” and our Moon stands as the largest natural satellite of any planet — that is, if you subscribe to bouncing Pluto and Charon out of “the club” — in contrast to its primary of any moon in our solar system.

ESA’s Rosetta orbiter has now moved in so close to its comet quarry that the primordial body overwhelms the screen, and thus its snapping mapping mosaics to capture the complete scene of the bizarre world so it can find the most suitable spot for the momentous Philae landing – upcoming in mid-November.

In fact Rosetta has ‘drawn and quartered’ the comet to collect high resolution views of Comet 67P/Churyumov-Gerasimenko with the navcam camera on Sunday, August 31. [click to continue…]

Now less than 25 days from her history making rendezvous with the Red Planet and the critical Mars Orbital Insertion (MOI) engine firing, India’s MOM is in good health!

The Mars Orbiter Mission, or MOM, counts as India’s first interplanetary voyager and the nation’s first manmade object to orbit the 4th rock from our Sun on September 24, 2014 – if all goes well. [click to continue…]
