Aliens Send Mysterious Signals To Earth, Harvard Claims
Aliens might have been sending mysterious signals to Earth but scientists misunderstood it, claims a professor at Harvard University. Strange messages received on Earth from satellites might actually be leakage from a huge light-powered spaceship deep in space, says Avi Loeb of the Harvard-Smithsonian Center for Astrophysics. He claims that Fast radio bursts (FRB), which have perplexed scientists, could be evidence of advanced alien technology.
Fast radio bursts, whose source is yet to be identified are flashes of radio emissions lasting milliseconds. They were first discovered in 2007 when scientists stumbled across data that showed a burst in 2001. While only a few have occurred since that time, scientists noticed that FRB arrive in apparently organized patterns.
Loeb thinks that these patterned signals might be some mysterious leakage of alien communication signals from planet-sized transmitters. Originally misunderstood as random radio signals, near about two thousand such strange signals have been detected by massive radio telescope like the Parkes Observatory in Australia. Now scientists are debating whether these mysterious messages are sent by aliens to the humans on Earth, or if these are again just random signals from long lost satellites, the Independent reports.
After a number of investigations and researches, scientists reveal that these radio signals are sent from distant galaxies which are billions of light year away from Earth. Loeb thinks that the transmitters that produce the FRB are powering interstellar probes in distant galaxies. Attempting to ascertain the origin of the radio signals, Loeb and other fellow Harvard academic Manasvi Lingam have studied the signals extensively to determine if the messages could emanate from a radio transmitter, the Science Examiner reports.
In a paper exploring the possibilities of alien technology, and to be published in The Astrophysical Journal Letters, the scientists formulated the features of these radio signals in details. It would require a planet-sized solar-power generator to catapult messages across the galaxy. However, researchers remain far from confirming whether the source of these “messages” are actually from extraterrestrials.
Martian Aliens May Have Contributed To The Birth Of Humans, Astronomer Says
A leading astronomer says that we might have Martian aliens to thank for the existence of human race. He believes that there is a great chance the Red Planet has lent Earth the materials for life through a great collision with an asteriod in the past.
Alien Space Particles Can Make Planes Drop From Sky
Scientists are warning about the dangers of alien space particles which can wreck havoc on airplanes. There have been ample reports where subatomic space particles interrupt airlines computer systems, and at one time, even caused a plane to suddenly make a nosedive.
Alien Bugs Will Be Locked Up When They Land Earth, Scientists Say
Scientists say that if alien bugs from Mars are carried back here on Earth, they can be seriously catastrophic to our immune systems. A secure containment for these extraterrestial microbes should ideally be set up to ensure that they will be locked up.
Supernova Discovery Hours After Blast Gives Amazing Details
An interesting supernova discovery surface this week as astronomers find a new outward sign a star explosion. The supernova was spotted just hours after explosion, providing amazing details on what occur right before the blast.
Alien Contact May End Life On Earth, Experts Warn
Leading experts on extraterrestial detection say that Earth may not be able to handle an alien contact. Basic protocols are already in place but experts warn that these may not be enough to avert any catastrophe.
Earth Gets Its Third Near-Miss Through Asteroid BH30
The asteroid BH30 missed the Earth as it passed through the planet on Jan. 30. The asteroid which was of the size of a car is reportedly the third space rock that was supposed to hit the Earth as was detected by scientists days before their closest flyby to the planet.
