Archives Acquires Papers of Geophysicist O. H. Gish

Oliver H. Gish

On 15 June 2015, Nancy R. Crow (granddaughter of former DTM staff scientist Oliver H. Gish) and Mark Skrotzki visited DTM and presented us with 13 boxes filled with Gish's professional and personal papers - correspondence, photographs, research notes, and computations.

The papers document Gish's research at DTM (1922-1948) and at other laboratories and universities throughout his long career. He was a recognized authority in atmospheric electricity and electrical currents in the Earth and designed instruments for the Explorer II manned balloon flight into the stratosphere in 1935. In the late 1940s, Gish and physicist George R. Wait led a pioneering, joint DTM-U.S. Air Force project to investigate the electrical fields in thunderstorms using B-29 bombers.

Stories From the Las Campanas Belles Blog: The Real Belles

Las Campanas Belles

"We thought hard about the title for this blog before going for the pun 'Las Campanas Belles.' But the pun isn't necessarily obvious, I realize." says DTM Astronomer Alycia Weinberger in this blog post from Las Campanas Belles on 30 May 2015.

Giant Magellan Telescope Partners Approve $500 Million For Construction

Giant Magellan Telescope

The Giant Magellan Telescope (GMT) has passed a major milestone as 11 international partners—including Carnegie—approved its construction, which secures the project’s future and unlocks more than $500 million of work on the world’s most powerful optical telescope.

The 25-meter telescope will be part of the new generation of extremely large optical telescopes. The GMT will enable astronomers to look deeper into space and further back in time, producing images up to 10 times sharper than those produced by the Hubble Space Telescope. It is expected to see first light in 2021 and be fully operational by 2024.

DTM's #girlswithtoys

Marion Garcon

After an NPR interview ran on May 16 quoting a male astronomer saying, "Many scientists, I think, secretly are what I call 'boys with toys'", the reactionary hashtag #girlswithtoys went viral on Twitter.

Female scientists from around the world posted photos of themselves on Twitter with the tools and machines they use to conduct their research everyday. Besides proving a point, the photos also provide a gateway into the fascinating equipment scientists use on a daily basis. Here are Carnegie's #girlswithtoys doing cool, smart science.

The Hunt for Extrasolar Planets with Paul Butler

Paul Butler

Over 120 people descended upon Carnegie's Broad Branch campus on Thursday, 14 May 2015, to hear DTM Astronomer Paul Butler reveal the truth about alien worlds and the origin of science for the final installment of Carnegie's 2014-15 Neighborhood Lectures Series.

In the past 20 years, more than a thousand extrasolar planets have been found, first from ground-based precision Doppler surveys, and more recently by the Kepler space mission. Butler and his colleagues have concentrated on building precise Doppler systems to survey the nearest stars. Systems at Lick, Keck, AAT, and Magellan have found hundreds of planets, including five of the first six extrasolar planets, the first saturn-mass planet, the first neptune-mass planet, the first terrestrial mass planet, and the first multiple planet systems.
