This Expert From NASA Says Earth May Have Already Been Visited By Aliens

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.

I spy with my little eye … a celestial eye? Our Hubble Space Telescope (@NASAHubble) spotted this brilliant cloud of colorful gas in the constellation of Centaurus, around 4,900 light-years from our home planet. It’s distinctive eye-like shape, with a bright inner shell of gas and a more diffuse outer shell that extends far from the nebula, looks as if it could be the result of two separate ejections of gas. But this is in fact not the case: studies of the object suggest that they were formed at the same time, but are being blown from the star at different speeds. The powerful jets of gas emerging from the ends of the large structure are estimated to be shooting away from the star at speeds of up to 217,500 miles per hour. By the standards of astronomical phenomena, planetary nebulas like this one are very short-lived, with a lifespan of just a few tens of thousands of years. Since launching our Hubble Space Telescope in 1990, our view of the universe and our place within it has never been the same.

He went on to say how scientists much challenge their assumptions as ‘the size of the “explorer” might be that of an extremely tiny super-intelligent entity,’ he says.

Dr. Colobano also believes scientists are married to the idea that they need to discover modern human technology on other planets.

He argues how this factor could mean missing a sign of discovering a civilization inhabiting a planet much older than earth.

And as we may not be able to even imagine what that looks like, we just may miss it.

A lucky observation! 🔭 Close to the central plane of our Milky Way galaxy, our @NASAHubble Space Telescope spotted this little-known nebula billowing out among the bright stars and dark dust clouds that surround it. Unlike many of targets of Hubble, this object has not been studied in detail and its exact nature is unclear. At first glance it appears to be a small, rather isolated region of star formation, and one might assume that the effects of fierce ultraviolet radiation from bright, young stars probably were the cause of the eye-catching shapes of the gas. However, the bright, boomerang-shaped feature may tell a more dramatic tale. The interaction of a high-velocity young star with the cloud of gas and dust may have created this unusually sharp-edged, bright arc. Such a reckless star would have been ejected from the distant young cluster where it was born and would travel at 124,000 miles per hour or more through the nebula. As a part of a “snapshot” survey, this image was taken during observations that are fitted into Hubble’s busy schedule whenever possible – without any guarantee that the observation will actually take place – making it a lucky observation. Since beginning its mission in 1990, Hubble has made more than 1.3 million observations, including this lucky observation, that help us learn more about our solar system.

Dr. Colobano shared:

‘Considering further that technological development in our civilization started only about 10K years ago and has seen the rise of scientific methodologies only in the past 500 years, we can surmise that we might have a real problem in predicting technological evolution even for the next thousand years, let alone 6 Million times that amount!’

He also shared how fast radio bursts that are being analyzed could potentially be out of date and encouraged ‘speculative physics’ grounded in solid theories.

Dr. Colobano also said that not every UFO sighting can be ‘explained or denied’.

FRBs or fast radio bursts are radio emissions that appear both randomly and temporary.

This makes that difficult to find as well as hard to study, as it is not known what causes the short and powerful bursts.

EXPLOSIVE! 💥💥💥This dark, tangled web formed in a very violent fashion — it is a supernova remnant, created after a massive star ended its life in a cataclysmic explosion and threw its constituent material out into surrounding space. This created the messy formation seen in this image from our @NASAHubble Space Telescope, with threads of red snaking amidst dark, turbulent clouds. This object is situated in the Large Magellanic Cloud, a dwarf galaxy that lies close to the Milky Way. The remnant is likely the result of a Type Ia supernova explosion; this category of supernovae is formed from the death of a white dwarf star that grows by siphoning material from a stellar companion until it reaches a critical mass and then explodes. When explosions like this have a well-known luminosity, they can be used as markers for scientists to measure distances throughout the universe and learn more about what’s out there.

Many have thought the FRBs could have been stars colliding or messages that were being artificially created.

When the very first FRB was spotted or ‘heard’ by radio telescopes in 2001 — it wasn’t actually discovered until 2007 when scientists where analyzing archival data.

But as it was both random and temporary, it took many years for astronomers to agree it wasn’t an issue with the telescope.

Harvard-Smithsonian Center for Astrophysics researchers say how FRBs could be used to study both the structure as well as the evolution of the universe — despite its origin not being fully comprehended.

A huge population of FRBs that are far away could possibly act as probes of material across large distances.

The study of this material show help scientists and researches a better understanding of basic cosmic constituents, like ordinary matter, dark matter as well as dark energy — all constituents that tell us how fast the universe is expanding.
