“Dark Universe” coming to the Hayden Planetarium

On November 2nd, Hayden Planetarium at the American Museum of Natural History in New York City will premier a new space show called Dark Universe narrated by Neil deGrasse Tyson:

DARK UNIVERSE, the new Hayden Planetarium Space Show premiering November 2, 2013, at the American Museum of Natural History, is produced by an acclaimed team that includes astrophysicists and data visualization experts.

DARK UNIVERSE celebrates the pivotal discoveries that have led us to greater knowledge of the structure and history of the universe and our place in it—and to new frontiers for exploration. The Space Show is narrated by astrophysicist Neil deGrasse Tyson.

DARK UNIVERSE was created by the American Museum of Natural History, the Frederick Phineas and Sandra Priest Rose Center for Earth and Space, and the Hayden Planetarium.

New astronomy observatory opens in Ethiopia

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 update

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:

Juno gravity assist successful despite safe mode + Amateurs image the flyby

The Juno spacecraft successfully ricocheted from earth yesterday to set itself on course to Jupiter (see earlier posting) : Juno goes into safe mode during Earth flyby – Spaceflight Now.

It went into safe mode, some time around closest approach to earth. In safe mode a spacecraft shuts most everything down except the most essential services and prepares to reboot on command from mission control. It’s a way of dealing with potential computer problems that might otherwise put the system into a permanent hanged state.

Despite this glitch, it looks like everything went well.

Amateur observers around the world were able to track and image the spacecraft during its visit: Amateur Images Show Juno’s ‘Slingshot’ Around Earth Was a Success – Universe Today
