NASA Announces Televised Chandra News Conference


WASHINGTON -- NASA will hold a news conference at 12:30 p.m. EST on Monday, Nov. 15, to discuss the Chandra X-ray Observatory's discovery of an exceptional object in our cosmic neighborhood.

The news conference will originate from NASA Headquarters' television studio, 300 E St. SW in Washington and carried live on NASA TV.

Media representatives may attend the conference, join by phone or ask questions from participating NASA locations. To RSVP or obtain dial-in information, journalists must send their name, affiliation and telephone number to Trent Perrotto at: [email protected] by 10 a.m. EST on Nov. 15. Reporters wishing to attend the conference in-person must have a valid press credential for access. Non-U.S. media also must bring passports.

Scientists involved in the research will be available to answer questions. Panelists providing analysis of the research include:
- Jon Morse, director, Astrophysics Division, NASA Headquarters in Washington
- Kimberly Weaver, astrophysicist, NASA's Goddard Space Flight Center, Greenbelt, Md.
- Alex Filippenko, astrophysicist, University of California, Berkeley

Nasa scientists recently made a stunning disovery of an exceptional object in our cosmic neighborhood, which stretches across more than half of the sky and are as large as the Milky Way.

NASA scientists are left scratching their heads after discovering two huge bubbles of gamma rays on either side of our galaxy and nobody knows how they got there.

The bubbles were found by NASA's Fermi Gamma-Ray Telescope, which scans the sky every three hours for high-energy light.

The feature spans 50,000 light-years and may have been fuelled by a wave of star births and deaths at the centre of the Milky Way.

Other researchers have suggested it might be the remnant of an eruption from a supersized black hole at the center of our galaxy.

Scientists now are conducting more analyses to better understand how the never-before-seen structure was formed. The bubble emissions are much more energetic than the gamma-ray fog seen elsewhere in the Milky Way. The bubbles also appear to have well-defined edges. The structure's shape and emissions suggest it was formed as a result of a large and relatively rapid energy release - the source of which remains a mystery.

NASA's Fermi is an astrophysics and particle physics partnership, developed in collaboration with the U.S. Department of Energy, with important contributions from academic institutions and partners in France, Germany, Italy, Japan, Sweden and the United States.
