Aliens Previously Populated Our Solar System?

Astrophysicist: ETs May Have Already
Lived and Died In Our Solar System

The big question: Did they leave artifacts behind for us to find?

Aliens Previously Populated Our Solar System?

     As science continues to search the cosmos for evidence of intelligent extraterrestrials and, at the very least, for habitable planets that might harbor even non-intelligent life, one scientist is raising another eye-opening question: Was there a time in the far distant past when an advanced civilization actually lived on one of the planets of our solar system, long before earthlings evolved?

Pennsylvania State University astrophysicist Jason T. Wright suggests that ancient aliens may have lived on nearby planets hundreds of millions of years ago, before vanishing without a trace.

Mysterious X-ray Signal Defies Known Physics

Mystery in the Perseus Cluster Mystery in the Perseus Cluster

     The Universe is a big place, full of unknowns. Astronomers using NASA’s Chandra X-ray Observatory have just catalogued a new one.

“I couldn’t believe my eyes,” says Esra Bulbul of the Harvard Center for Astrophysics. “What we found, at first glance, could not be explained by known physics.”

Together with a team of more than a half-dozen colleagues, Bulbul has been using Chandra to explore the Perseus Cluster, a swarm of galaxies approximately 250 million light years from Earth. Imagine a cloud of gas in which each atom is a whole galaxy—that’s a bit what the Perseus cluster is like. It is one of the most massive known objects in the Universe.

The cluster itself is immersed in an enormous ‘atmosphere’ of superheated plasma—and it is there that the mystery resides. . . .

. . . “A line appeared at 3.56 keV (kilo-electron volts) which does not correspond to any known atomic transition,” she says. “It was a great surprise.”

At first, Bulbul herself did not believe it. “It took a long time to convince myself that this line is neither a detector artifact, nor a known atomic line,” she says. “I have done very careful checks. I have re-analyzed the data; split the data set into different sub groups; and checked the data from four other detectors on board two different observatories. None of these efforts made the line disappear.” . . .
