WASHINGTON (Reuters) -- A strange and powerful burst of radio waves from near the center of our galaxy may have come from a previously unknown type of space object, U.S. astronomers reported on Wednesday.
Other experts nicknamed the mysterious source a "burper" and said there would be a race to scan for similar radio bursts.
"We hit the jackpot," said Scott Hyman, a professor of physics at Sweet Briar College in Virginia, who led the study.
"An image of the Galactic center, made by collecting radio waves of about 1 meter (3 feet) in wavelength, revealed multiple bursts from the source during a seven-hour period from September 30 to October 1, 2002 -- five bursts in fact, and repeating at remarkably constant intervals."
The burst came from the direction of the middle of the Milky Way galaxy, of which Earth is a part, and could have originated from as far away as 24,000 light-years or from as close as 300 light-years. A light-year is the distance light travels in a year, or about 6 trillion miles (10 trillion km).
