Nothing like experiment to show that a great theory sucks: In Space No One Can Hear your Nitrocellulose Explode – Wired Science.

The Ethiopian Space Science Society (ESSS) has opened a astronomical observatory in the Entoto mountains near the capital Addis Ababa: Ethiopia sets sights on stars with space programme – AFP/Phys.org.
When visiting Ethiopia with my wife, who is from Addis, I wondered whether the high, dry mountains, especially in the northern area of the country, would be an attractive area to put telescopes the way the mountains of Chile have become a popular site for observatories. Hope this new observatory marks the start of rapid growth in astronomical activity in Ethiopia.

Comet ISON (C/2012 S1) could become visible to low power telescopes and binoculars, and maybe even to the naked eye, in the next few weeks. The website The ISON Atlas aims to help people find out “Where to find Comet ISON in the sky”. The post for this month: OCTOBER 2013 | The ISON Atlas
Here’s an image of the comet taken by Adam Block at the Mt. Lemmon SkyCenter/University of Arizona:
