Reported by the LATimes, Friday (05/10/2013), the cloud is thought very large or relatively small in fact, depending on the reference point of the researcher. This object is much smaller than the two galaxies that are in them, but each of these clouds have a million times the mass of the solar system.
The researchers say, it looks about the size of a cloud of dwarf galaxies, but the cloud does not have a star in it. "What makes this puzzling discovery is that you can see the clouds floating freely in intergalactic space whose origin is a mystery," said Felix J. Lockman, an astronomer at the National Radio Astronomy Observatory.
Researchers currently do not know since when the clouds "wander" in outer space. In addition, researchers also have not been able to determine where the origin of the mysterious object and when the clouds will disappear.
These clouds do not emit light or energy, but the neutral hydrogen atoms that appear capable of issuing different radio signals. Astronomers using the National Science Foundation's Green Bank Telescope to measure the radio waves.
"Our next plan is to use the same telescope to see this type of cloud elsewhere. If they come from Andromeda, then we can find other clouds along the trail that leads to the galaxy," he explained.
