The search for extraterrestrial intelligence has looked for many different signs of alien life, from radio broadcasts to laser flashes, without success. However, recent research suggests that mysterious phenomena called fast radio bursts, millisecond-long flashes of radio emission, could be evidence of advanced alien technology. Specifically, these bursts might be leakage from planet-sized transmitters powering interstellar probes in distant galaxies.
To most cosmologists, the most plausible explanation for that uniformity of the cosmos is that, soon after the beginning of time, some unknown form of energy made the young Universe inflate at a rate that was faster than the speed of light.
Last year, Rene Heller from the Max Planck Institute for Solar System Research created a simulated message from an alien civilization a billion years older than Earth, and released it on Twitter and Facebook for the world crowdsource and decode.
For decades, scientists have held that Supermassive Black Holes (SMBHs) reside at the center of larger galaxies. These reality-bending points in space exert a extremely powerful influence on all things that surround them, consuming matter and spitting out a tremendous amount of energy.
Since the 1960s, astronomers have been aware of the electromagnetic background radiation that pervades the Universe. Known as the Cosmic Microwave Background, this radiation is the oldest light in the Universe and what is left over from the Big Bang. By 2004, astronomers became aware that a large region within the CMB appeared to be colder than its surroundings.
The discovery of hydrogen in the water plumes suggests that although the moon is just 505 kilometers in diameter, it may harbor under its surface the chemicals and processes capable of supporting microbial life.
For years, scientists have been piecing together evidence of peculiar phenomena known as red sprites, blue jets, pixies and elves – exotic types of electrical discharges that emanate from thunderstorms.
In the past year, Sun Weidong, a highly decorated geochemist, has ignited a passionate online debate with claims that the founders of Chinese civilization were not in any sense Chinese but actually migrants from Egypt.
