Unmasking Europa

by Phyllis Lang

RAC enjoyed a special pre- Astronomy Days presentation on Friday, January 29 by Dr. Richard Greenberg entitled “Unmasking Europa: the Search for Life on Jupiter’s Ocean Moon”. Dr. Greenberg is a Professor Emeritus of Planetary Sciences at the University of Arizona.

He discussed his research and that of others in regard to the Jovian moon Europa. Dr. Greenberg’s research team derived the thin-ice model of Europa which describes an active icy crust that covers a liquid saline water ocean of about 100 miles depth. The floor of the ocean is thought to be rocky.

The presentation included incredibly detailed pictures of Europa and cutting-edge research results from the Galileo mission to Jupiter. An active question and answer session followed. Several attendees were able to purchase a signed copy of Dr. Greenberg’s book, “Unmasking Europa: the Search for Life on Jupiter’s Ocean Moon”.

We thank the NC Museum of Natural Sciences for helping us arrange this presentation by Dr. Greenberg.

Fall Observing Sessions

by Web Administrator

The Fall observing season is here and that means good weather for getting out under the stars. For the early fall sessions, which usually have mild weather and decent conditions, the club was able to observe in August and September 2015, but was clouded out in October. However, two out of three was not bad and members got in some eagerly awaited time under the stars.

September Meeting: A Multitude of Multiverses

by Web Administrator

The September indoor RAC meeting was held in the Daily Planet Theater and member Dr. Steven Christensen presented on multiverses. This topic can be very hard to grasp for non-physicists, but as usual, Dr. Christensen did a great overview of the background and current theories of this very heady topic, but in a very accessible way so that everyone could understand it. However, even folks familiar with the topic learned something during this presentation.

Thanks again to Steve for taking the time to make this great presentation. Unfortunately, due to circumstances beyond RAC’s control, there is no recording of this event.

NC Museum of Art Observing Session

by Web Administrator

The Raleigh Astronomy Club and Morehead planetarium partnered with North Carolina Museum of Art for the 2015 Stargazing in the Museum Park member event. In addition to beverages supplied by local breweries, the crowd of over 300 enjoyed clear cool skies and views of the International Space Station (ISS), M13, the Moon, and Saturn. Saturn was definitely the crowd favorite with multiple scopes providing views of the ringed planet in white light and through colored filters (like orange to enhace the bands on the surface).

Perseid Meteor Week and July RACOBS

by Web Administrator

The Perseid metor shower is one of the better showers of the year. This year’s event was widely anticipated because the Moon did not interfere with the veiwing. Here in Raleigh, we were doubly luck as some cooler drier weather also happened to settle into the area making conditions very good indeed. Many members and public got some gret views due to a public observing session by Morehead Planetarium, a RAC impromptu observing session, and the regulary scheduled RACOBS

Unraveling Starlight: July 2015 Indoor Meeting

by Web Administrator

The RAC July Indoor meeting featured a presentation by Dr. Barbara Becker on her resaerch into the life and accomplishments of British amateur astronomers William and Margaret Huggins in the 19th century work. In a time when amateurs did a great deal of the astronomical work, this husband/wife team did pioneering work in the field of spectroscopy. Much of modern astronomy is rooted in spectral analysis of the light from stars, nebula, galaxies and many other objects and their contributions made significant progress to the state of the art.
