Ice Crystal Halos

Dean Ketelsen (photo copyrighted by him) took this great photo of ice crystal halos that are not normally seen because the Earth is in the way. But flying in an airplane and paying attention gave him this reward. The British site "Astronomical Optics" is perhaps the best such website in the world at this moment. Dean also posts many photos at his blog theketelsens.blogspot.com. Right now there are start-of-monsoon photos from Kitt Peak, and many others. There's a infrared- airglow video about halfway down the page. Larger photos of the sub-halos at the astronomical optics site.

More Eyes on the Skies

The Giant Magellan Telescope Project has announced that Fundação de Amparo à Pesquisa do Estado de São Paulo has joined. Read more about GMT and other big telescopes coming on line in the next decade in this NY Times article by Dennis Overbye:

The photo is a book cover from a modern reprint, by Emerson-Adams Press in 1998, of perhaps the most important book in the field, first published in English in1966 (published in Russian by Shklovsky alone in 1962)

Should Humanity Try to Contact Intelligent Aliens?

This article about communicating with alien civilizations contains quotations by Seth Shostak, Chris Impey of Steward, and Steven Dick and Michael Michaud.

Congratulations to our Senior Bachelor of Science Students

Congratulations to our Senior Bachelor of Science Students

On Thursday, April 24, the Dept. of Astronomy honored the seven matriculating senior undergrads at a brief pre-colloquium ceremony. The photo shows Director Buell Jannuzi with, from left to right, Kyle Pearson, Cassandra Lejoly, Spencer Wallace, Amanda Walker-LaFollette, Ian Cates and Lauren Biddle, (Christen Jones, not pictured). Undergrad Studies Program Coordinator Yancy Shirley also announced that Amanda Walker-LaFollette is this year's recipient of the Research Excellence Award, and Cassandra Lejoly received the Astronomy Outstanding Senior award. Four of the students then gave 15-minute colloquia each to an appreciative audience of professors, postdocs, grad students, and undergrads. All of the members of the Astronomy Department wish each of the seven undergrads the best of luck in their chosen future endeavors.

RIP Russ Warner

"It saddens me to inform you that Russ Warner passed away last week. Many of you had interactions with Russ as he held several positions over the 29 years he worked at Steward Observatory. Russ was initially hired in 1984 as a Project Manager for Mt. Graham Observatory, where he worked on the original site testing for what would become Mt Graham International Observatory. In about 1986, Russ switched hats to manage the Mirror Lab. In 1992, he became Administrative Manager of the Sub-Millimeter Telescope Observatory. In 2000, he transferred as Administrative Manager to the Technical Division (now Engineering Technical Services). He was our Building Monitor, Department Export Control Administrator, and manager for many years. Russ enjoyed travelling both internationally and domestically. He is survived by his wife, Anne, and will be missed dearly by family and friends."
