Lick Observatory on budget chopping block

Lick ObservatoryLast month something near and dear to many of us — Lick Observatory perched atop Mt. Hamilton in hills of east San Jose — was placed on the UC’s chopping block. From the KQED article (linked below):

On top of Mount Hamilton, east of San Jose, the Lick Observatory is home to the oldest professional telescope in California. Read more »

“What is color?” The 2014 Flame Challenge

The Alan Alda Center for Communicating Science at Stony Brook University is challenging scientists to take part in the 2014 Flame Challenge and answer a vibrant question asked by 11-year-olds from around the country:

What is Color?

The Flame Challenge is an international contest started by Alan Alda that asks scientists to communicate complex science in ways that would interest and enlighten an 11-year-old.

If you are a scientist, or a teacher of 11 year olds, join the fun!

Colloquim at Sac State: Measuring the Universe with Gravitational Lenses

The following colloquium is free and open to all.

Dr. Chris Fassnacht, UC Davis, will present his lecture, “Measuring the Universe with Gravitational Lenses” on Thursday, February 11, 2010, at 4pm in Mendocino Hall 1015, Sacramento State University.  This lecture is free and open to the public.

Chris Fassnacht received his AB degree from Harvard College and immediately afterward joined the Peace Corps, where he served as a secondary school math and science teacher in Ghana, West Africa.   After returning, he received a PhD from Caltech.  He held postdoctoral fellowships at the National Radio Astronomy Observatory in Socorro, NM and the Space Telescope Science Institute in Baltimore, MD.  He is currently an associate professor in the physics department at UC Davis, where he has been for the last seven years.

Prof. Fassnacht’s research involves using gravitational lenses to measure the rate at which the Universe is expanding and how galaxies such as the Milky Way are assembled.

Jupiter pummeled, leaving bruise the size of the Pacific Ocean

infrared image of Jupiter taken with Keck IIThe scar from the probable impact appeared July 19 in Jupiter’s southern hemisphere, and has grown to a size greater than the extent of the Pacific Ocean. This infrared image taken with Keck II on July 20 shows the new feature observed on Jupiter and its relative size compared to Earth.

BERKELEY — Something slammed into Jupiter in the last few days, creating a dark bruise about the size of the Pacific Ocean.

The bruise was noticed by an amateur astronomer on Sunday, July 19. University of California, Berkeley, astronomer Paul Kalas took advantage of previously scheduled observing time on the Keck II telescope in Hawaii to image the blemish in the early morning hours of Monday, July 20. The near infrared image showed a bright spot in Jupiter’s southern hemisphere, where the impact had propelled reflective particles high into the relatively clear stratosphere.

In visible light, the bruise appears dark against the bright surface of Jupiter.

The observation made with the Keck II telescope marks only the second time astronomers have seen the results of an impact on the planet. The first collision occurred exactly 15 years ago, between July 16 and 22, 1994, when more than 20 fragments of comet Shoemaker-Levy 9 collided with Jupiter.

NASA Releases Restored Apollo 11 Moonwalk Video

NASA moon logoWASHINGTON, July 16 /PRNewswire-USNewswire/ — NASA released Thursday newly restored video from the July 20, 1969, live television broadcast of the Apollo 11 moonwalk. The release commemorates the 40th anniversary of the first mission to land astronauts on the moon.

The initial video release, part of a larger Apollo 11 moonwalk restoration project, features 15 key moments from the historic lunar excursion of Neil Armstrong and Buzz Aldrin.

A team of Apollo-era engineers who helped produce the 1969 live broadcast of the moonwalk acquired the best of the broadcast-format video from a variety of sources for the restoration effort. These included a copy of a tape recorded at NASA’s Sydney, Australia, video switching center, where down-linked television from Parkes and Honeysuckle Creek was received for transmission to the U.S.; original broadcast tapes from the CBS News Archive recorded via direct microwave and landline feeds from NASA’s Johnson Space Center in Houston; and kinescopes found in film vaults at Johnson that had not been viewed for 36 years.

NASA Television will provide an HD video feed of the Apollo footage hourly from 12 – 7 p.m. on July 16 and 17. Each feed is one hour. For NASA TV streaming video, downlink and schedule information, visit:
