Signals Detected From Distant Dwarf Galaxy Stun Observers.
Scientists have detected 15 strange radio bursts coming from distant dwarf galaxy.

"One day, we might receive a signal from a planet like this, " Hawking says in the documentary, referring to potentially habitable alien world known as Gliese 832c.
Some predict they are natural, such as exploding stars, while other scientists believe that they are extraterrestrial signals which were initially sent Earth's away.
The messages were picked up by Breakthrough Listen, a major project launched by Stephan Hawking and internet investor Yuri Milner in 2015, as part of their programme to find signs of intelligent life in the universe.

Using the Green Bank Telescope in west Virginia, The Listen Science Team detected the bursts in the early hours of Saturday 26 August.
The origin of a fast radio burst in this type of dwarf galaxy suggests a connection to other genetic events that occur in similar dwarf galaxies, said Casey Law, an astronomer university of California Berkeley in the U.S.
The latest signals, dubbed FRB 121102, however, have been detected 15 times, which essentially rules out the possibility of a supernova or other natural occurrences.
Extremely bright exploding stars, called super luminous supernovae and long gamma ray bursts also occur in this type of galaxy, he said.
That means that those pulses left their galaxy when our entire solar system was just two billion years old long before multi called organisms appeared on Earth.
First radio bursts, which flash for just a few milliseconds, created a stir among astronomers because they seemed to be coming from outside our galaxy, which means they would have to be very powerful to be seem from Earth, and because none of those first observed were ever seen again.
Scientists had initially been worried that the bursts might not be coming from space, and were actually a misunderstood signals from Earth like when astronomers found that they had accidentally detected their own microwave.
But the recent work showed that the messages are coming from outside the Earth's atmosphere.
