Are Aliens Real?

Do aliens exist? This is a really interesting question and one that NASA has been trying to understand, explore, and figure out for a long time. We have not yet discovered life on any other planet, and we have not seen any scientifically supported evidence for extraterrestrial life.

But if we think about life on this planet, beyond the big things the elephants, the whales, redwoods trees and focus on the tiny things, nearly everywhere on Earth that we've looked, we've found microbial life. Humans often wonder whether or not we are alone in this universe. Though that question was not answered in 2020, many discoveries seemed to increase the prospect of extraterrestrial entities existing.

In 1995 a pair of scientists discovered a planet outside our solar system orbiting a solar-type star. Since that finding—which won the scientists a portion of the 2019 Nobel Prize in Physics—researched have discovered more than 4,000 exoplanets, including some Earth-like planets that may have the potential to harbor life. These planets may be the key to answering the questions, do aliens exist and are aliens real. rhttps://www.usatoday.com/story/news/nation/2021/06/04/pentagon-ufo-report-raises-questions-aliens-what-scientists-say/7487632002/?gnt-cfr=1eal?

Scientists have announced that they discovered possible life on Venus, Earth's closest neighbor in the solar system. In the clouds above the planet, a group of astronomers from all over the world found traces of a chemical only created by living beings. According to the Washington Post, the chemical is called phosphine. Traces of phosphine that appear in Earth's skies are directly linked to human activity, scientists say.

Back in May, The New York Times reported that Navy fighter pilots had strange encounters with mysterious flying objects eight times between 2013 and 2019. According to the reports, the fighter pilots and other military officials couldn't explain where the flying objects had come from. The U.S. Pentagon has a program to investigate these UFOs called the Unidentified Aerial Phenomenon Task Force, according to The New York Times. Some think these UFOs might not be actually be little green men from outer space, but the program's findings are still a bit of a mystery to reporters and others in the public.

The number of UFO sightings is currently flying at an all-time high, according to data cruncher and blogger Sam Monfort. The alien expert reckons there have been more than 100,000 recorded UFO sightings in the past 100-plus years. From an "alien autopsy" video dating back to 1995 to a video of fighter jets apparently chasing a UFO over the M5, there are hundreds of videos that people have claimed to be proof of alien life. here's even a clip of a UFO supposedly attacking a Taliban compound, as well as "sightings" in Peckham and Warminster.

At the end of August, alien hunters from the Breakthrough Listen project detected "fast radio bursts" coming from a mysterious cluster of stars – which may have been produced by "extraterrestrial civilizations".

Far North Queensland is considered a UFO hotspot, with several sightings of mystery aircraft in the sky over several decades. A UFO shaped like a tic-tac stalked a US Aircraft carrier for days before vanishing into thin air, according to a Pentagon report which emerged in May, 2018. The object - which could reportedly hover in mid air and make itself invisible bamboozled US Navy fighter pilots during a training exercise in the Pacific Ocean in November, 2004.

Researchers should report evidence for alien life on a scale similar to the technological readiness level scale commonly used to assess the readiness of spaceflight components, a new paper argues. The goal is to make the search for life less "binary" life or no life — and to express it more accurately in terms of agreed-upon scientific uncertainty. The newly proposed alien-life evidence scale was outlined in a study published online Oct. 27 in the journal Nature that was led by NASA chief scientist Jim Green. The scale includes seven levels, which are subject to change depending on the type of environment involved and how the scientific community responds.

If scientists were to adopt the CoLD scale, the first of its be seven steps, or levels, would be the actual detection of a potential biosignature. Next, scientists would need to rule out contamination before demonstrating how the signal could be biological in origin. Nonbiological sources would then need to be ruled out, followed by an independent additional detection of a similar biosignature. Further observations would need to rule out nonbiological ideas before, finally, follow-up observations showed other examples of biological activity in the same environment, making a detection a level 7 essentially, proof of alien life.
