WASHINGTON - A group of scientists who worked on data from the Fermi Space Telescope NASA's Gamma-Ray said that they had found two energy bubble that had erupted from the center of the Milky Way. Bubble is located 25,000 light-years and have the same energy with 100,000 supernova explosion.
"The bubbles are large," said Doug Finkbeiner of the Harvard-Smithsonian Center for Astrophysics, led the team that discovered these bubbles. Similarly, as quoted from The New York Times, Friday (11/12/2010).
The source of the bubbles are still a mystery. One possibility that the wave is getting power from waves of birth and death of stars in the galactic center. Another option is the bubble is getting energy from the black hole at the center of Milky Way galaxy.
"We think if we know a lot about our galaxy, but it is not," said David Spergel, an astrophysicist at Princeton University that showed that the bubbles as big as the Milky Way galaxy.
Jon Morse, the head of astrophysics at NASA headquarters said the findings indicate that the universe is full of surprises.
One of the most surprised person was Dr. Finkbeiner. A year ago he became the group led by Gregory Dobler from the Kavli Instiute for Theoretical Physics in Santa
Barbara, California, who said that they had seen a mysterious fog full of energy around the center of Milky Way galaxy. At that time Dr. Finkbeiner and his colleagues speculate that the bubble is generated from a wave of darkness. Center of the Milky Way galaxy is a 'home' for all energy phenomena, including the giant black hole. However, several theories of the cosmos also states that the wave of darkness may be concentrated there. In theory of particle collisions could cause a wave of dark rain Gamma rays.
Further analyzed, in addition to larger than a Dr. Finkbeiner and his colleagues expect these galaxies proved to have limits. Meanwhile, waves of darkness have a more biased.
"A wave of darkness has been there for billions of years," explained Dr.Finkbeiner. "If something has been occurring for billions of years, you probably would not expect a clear boundary," he added.
Dr. Finkbeiner and other scientists said this not mean that a wave of darkness does not exist in the formation of galaxies but because the waves are very difficult to see.
