One NASA scientist says intelligent aliens have possibly, already visited our Earth.

But because of their ‘extremely tiny’ size, we may have missed it.

Heads or Tails? Using Chandra X-ray Observatory (@nasachandraxray) data, astronomers captured this dramatic image of an enormous tail of hot gas stretching for more than a million light years behind a group of galaxies falling into the depths of an even-larger cluster of galaxies. Discoveries like this help astronomers learn about the environment and conditions under which the Universe’s biggest structures evolve. Galaxy clusters are the largest structures in the Universe held together by gravity. While galaxy clusters can contain hundreds or even thousands of individual galaxies, the lion’s share of mass in a galaxy cluster comes from hot gas, which gives off X-rays, and unseen dark matter.

Silvano P. Colombano shares that ‘super intelligent’ aliens who are capable of interstellar space-travel, in theory — would posses technology that humans cannot even comprehend.

NASA is currently looking for other civilizations in the universe, or as the official program is titled, ‘Search for extraterrestrial intelligence.’

Dr. Colombano in March shared how important it is for scientists to expand what they believe extra-terrestrials look like when speaking at the California SETI-backed Decoding Alien Intelligence Workshop.

‘I simply want to point out the fact that the intelligence we might find and that might choose to find us (if it hasn’t already) might not be at all be produced by carbon-based organisms like us,’ his report read.
