Discovery circumstances of the first interstellar asteroid

Join us on Friday, December 8th, 2017 at 1:30 pm in Physics & Astronomy Seminar Room 100 to uncover the circumstances that led to the discovery of the first interstellar asteroid. Dr. Robert Weryk from the University of Hawai'i at Manoa, a Western Science alumnus, will be talking about his role and the science that led to the identification of this interstellar object. The full abstract of the talk can be found below:

Discovery circumstances of the first interstellar asteroid

For the first time ever astronomers have studied an asteroid that has entered the Solar System from interstellar space. Observations from ESO’s Very Large Telescope in Chile and other observatories around the world show that this unique object was traveling through space for millions of years before its chance encounter with our star system. It appears to be a dark, reddish, highly-elongated rocky or high-metal-content object. Our team from the Pan-STARRS observatory – being the first to detect the interstellar visitor – has chosen the name 'Oumuamua’ for our discovery. The name is of Hawaiian origin and means a messenger from afar arriving first. I will discuss the results that appeared in Nature on 20 November 2017.
