THE FOLLOWING ITEM WAS ISSUED BY ASTRONOMY MAGAZINE IN WAUKESHA, WISCONSIN, AND IS POSTED ON MY BLOG FOR YOUR INFORMATION.
29 May 2013
This release is based on a story in the June 2013 issue of Astronomy magazine: http://www.astronomy.com/~/media/Files/PDF/Magazine%20articles/ET-with-infrared-light.pdf
Until recently, one of the ultimate mysteries of the universe — how many civilizations may exist on planets orbiting other stars in the Milky Way Galaxy — relied on the possibility of detecting intelligent beings by radio signals. Now a team of astronomers, engineers, and physicists from the University of Hawaii, the University of Freiburg, and elsewhere has proposed a new and powerful technique to search for intelligent life.

Mercury Craters named after world renowned artists, musicians and authors
Adapted from MESSENGER Mission News (March 26, 2013)
The International Astronomical Union (IAU) — the arbiter of planetary and satellite nomenclature since its inception in 1919 — recently approved a proposal from the MESSENGER Science Team to assign names to nine impact craters on Mercury. In keeping with the established naming theme for craters on Mercury, all of the newly designated features are named after famous deceased artists, musicians, or authors or other contributors to the humanities.

Progress on the GPI exoplanet imager integration
The Gemini Planet Imager (GPI) is a next generation adaptive optics instrument being built for the Gemini Observatory. This is an ambitious project with the goal of directly imaging extrasolar planets orbiting nearby stars. The instrument is currently being integrated at the University of California at Santa Cruz. After more than a year of testing in a fixed orientation in a clean room, on March 7, 2013, the 2,030 kg instrument was set up on a crane and flexure rig. In collaboration with the UCSC team, we prepared this time lapse video showing GPI being set up in its new position.

Featuring the Women Of Science #WomenOfScience
Today I would like to share with you an idea for the International Women’s day on March 8 2013. If you work in an institution, university, or non-profit related to science, have you taken note of the number of women around you? In astronomy and planetary science, it is not too bad even if it is not perfect, but some “hard” science groups, like physics or computer science, clearly have a low proportion of women in their ranks. I will not elaborate on the reasons for such lack of representation; instead, I propose to focus on the bright side.
The Russian Meteor and Lessons Learned on Meteor Impacts
Almost 12h after the event, it is time to gather my notes on the Russian meteor event (#RussianMeteor) and my thoughts on this impact and those which may come soon.

Act now! Save Your Science from Sequestration
An important message
We are asking YOU, the US-based SETI Institute Fans, our followers on Facebook, Twitter and Google+ to help us save science from sequestration. Send a FAX or write a letter and even send a tweet to your members of Congress. Today is the day you should act to save science!
Kepler Planet-Hunter is Healthy and Back!
I mentioned in my previous post the detection of an issue on the Kepler spacecraft which pushed the engineering team to put the space telescope in safe mode for 10 days. The Kepler team announced today that science operation was reinitiated yesterday. That’s a great news!

Kepler is Sick and Resting: “Mountain View, we have a problem”
“Mountain View, we have a problem…”
NASA Kepler Manager at NASA Ames, Mountain View announced today that they interrupted the science operation of the spacecraft, due an issue with one of the reaction wheels. Kepler is equipped with four reaction wheels which are used to accurately point the telescope. One failed in July 2012 and today the team announced that they detected issues with a second one. Kepler needs three reaction wheels to be used properly, if this one fails the mission is most likely over. That’s not good news.
An update on the Siding Spring Observatory
A short followup of my post sent last night with a good news through an official announcement by the Australian National University posted today.
In a nutshell, no telescopes have suffered major damages from the bush fire, but the astronomer’s lodge, the visitor’s center and several staff houses have been destroyed or seriously damage.

Siding Spring Observatory is being threatened by a bush fire.
This is definitely not the kind of news that astronomers like reading about… The Siding Spring Observatory in New South Wales, Australia, is currently threatened by a large uncontroled bush fire.
