The alien radar signals that puzzled scientists for more than five decades have finally been explained. Researchers at Boston University (BU) found that the mysterious "150-kilometer echoes" received on earth at dawn could be caused by the sun.
The Mysterious Alien Radar Signals
Science Mag reports that for more than 50 years, scientists failed to trace the origin of the mysterious "150-kilometer echoes." These alien radar signals, which were first detected in the 1960s, have been appearing at dawn at an estimated altitude of 150 kilometers.
The mysterious "150-kilometer echoes" would descend from the sky within the morning and grow stronger as hours pass by. The alien radar signals would rise back to 150 km during the afternoon and would disappear during sunset. These would also fade during a solar eclipse and grow louder during solar flares.
Uncovering The Mystery Behind The Alien Radar Signals
According to the Daily Mail, a new study published in the latest issue of Geophysical Research Letters has come up with a possible explanation about the alien radar signals. Space physicist Meers Oppenheim and his colleagues at BU found that the mysterious "150-kilometer echoes" are produced by the energy from the sun's radiation.
Oppenheim and his team developed a computer model to simulate particle interactions in the atmosphere of the earth. The researchers based their study on the concept that the sun's UV light can strip oxygen and nitrogen molecules. They found that the vibrations of these ions create waves that are strong enough to reproduce radar beams.
The Relevance Of Knowing The Origin Of The Alien Radar Signals
"When you actually figure out something that nobody's ever figured out before, that's when it's really worthwhile," Oppenheim shared. He added that this new discovery could help researchers in tracking the upper atmosphere's movement and in understanding atmospheric tides.
Jorge Chau, a scientist from the University of Rostock in Germany who tried to figure out the origin of the alien radar signals in 2013, commented that Oppenheim and his team are on the right track. He said that there are still unanswered questions about the "150-kilometer echoes," however, the initial results of the recent study are very convincing.
