Professor John Zarnecki told Newsweek that it seems unlikely an advanced civilization would travel vast distances only to deploy balloons over Earth.
At 40 light years away from Earth, TRAPPIST-1's four Goldilocks zone planets are one of the prime candidates for finding extra-terrestrial life.
Researchers looked at the possibility of one nation monopolizing any alien interaction, and the likelihood of international conflict.
The year 2022 has seen Congress hold a UFO hearing, a Russian official confirm UFO studies and China involved in a radio sweep for alien signals.
America's "space agency" picking up the UFO ball was bound to raise eyebrows and concerns for NASA's reputation. But if it's handled well, the commission could do more than shed much-needed light on UAPs. It could also give Americans a masterclass in the most basic, most important, and unfortunately, most boring topic in science: Standards of Evidence. They are the key to knowing if we are alone in the Universe or not.
From fast radio bursts to pulsars and other strange signals, the alien-hunting FAST telescope has made a number of discoveries in its short life.
The exoplanet orbits its dwarf star in 35 days and has a very cold surface temperature, but astronomers believe it could still host life in its clouds.
Researchers say determining intelligence across the galaxy could give clues to our own fate.
"There is a reasonable chance that the planet hosts a large ocean underneath the atmosphere at pressures and temperatures similar to those in the Earth's oceans," researcher Nikku Madhusudhan said.
The Earth may be crawling with undiscovered creatures with a different biochemistry to life as we know it.
Human's evolved through a series of highly unlikely events—so finding another intelligence like us would be like winning the lottery many times over.
Astronomer says he is "not paying much attention to what happens in Area 51."
Do you care about the search for extraterrestrial intelligence? Let these researchers know.
Breakthrough Listen is a program designed to search for evidence of alien life by scouring the the skies for distant radio signals.
Laguna Caliente in Costa Rica is one of the harshest environments on Earth for life.
Are we looking for aliens in the wrong way?
"I think that in this century we are going to be finding life beyond Earth," said Jill Tarter, a scientist at the SETI Institute research center in California.
The same heavy elements that boost our economy could boost theirs.
Radio waves are fast, but not fast enough to reach us before a civilization goes extinct.
There could be thousands of rocks from distant solar systems just killing time in our neighborhood.
"We cannot discount the possibility that it really is a spacecraft."
Douglas Vakoch of METI announced messages were sent to the GJ273 system over three days in October.
