From Kenneth Arnold’s first report of “flying saucers” to mass sightings like the Phoenix Lights and the mysterious Ariel School incident, numerous people have claimed encounters with UFOs and extraterrestrials, asserting they serve as actual physical evidence.


World UFO Day: Are we REALLY alone? 7 mysterious encounters that prove we aren't

Astrophysicist Adam Frank has warned scientists against sending signals to extra-terrestrials and trying to communicate with them, as he said that people should be cautious regarding these activities as humans are unaware of the potential of alien life out in space.

The physicist, who accepts that aliens may exist at least as microbial life beyond&nbsp;Earth, said that it is better to "lay low" and not try communicating with aliens which is similar to "sticking your head out the grass and saying we're tasty".&nbsp;

However, he thinks that at least microbial life present in the universe "can certainly be inhabited".

Speaking in the 5 Live Science Podcast, the astrophysicist said: "So I do talk about METI the messaging extra-terrestrial intelligence and in general, I'm not a big fan of it. Because really, we don't know what's out there, and it may be that the best decision is to kind of lay low."

"Don't stick your head above the grass and be like, 'hey, we're here, we're tasty'," he added.

<h2>Signals sent to aliens in the universe are like 'low hum', says astrophysicist</h2>

Speaking about the attempts made by humans to the cosmos through "been putting out emissions", Frank said that such efforts are similar to a "low hum" and not METI's scream into the void, the Daily Star reported. 
&nbsp; 
"When you do METI, you're really screaming into the void," he said and further emphasised how challenging it is to get heard in countless radio transmissions getting transferred in our galaxy.&nbsp;

"And unless somebody knew exactly where to look, they wouldn't hear us. There's all kinds of radio transmissions in the galaxy," Frank said.&nbsp;

"I think it's going to be pretty hard to imagine that microbial life hasn't evolved elsewhere in the universe, probably quite often. Now, animals, and then intelligence, that may be difficult for evolution to achieve, looking at Earth's own history. But I certainly think that life in general is going to be quite common in the universe," he further said.&nbsp;

Alien hunter says humans are 'tasty' for extraterrestrials, contacting UFOs can...

NASA scientist Dr Michelle Thaller proposed an interesting theory that hints at the existence of aliens on Venus, a planet that faces&nbsp;scorching 475°C (900°F) temperatures and remains enveloped in a thick acidic atmosphere. 
 
However, as per claims by Dr&nbsp;Thaller, the aliens are most likely hiding&nbsp;on Venus and are staying there amid conditions that are unbearable for humans. 
 
The new theory was proposed by Dr. Michelle Thaller, who works as a research scientist at the US-based Goddard Space Flight Centre. 
 
She stated that “possible signs of life” were already noticed within the carbon-dioxide-filled atmosphere, and added that she is certain about the existence of life somewhere.

“We see possible signs of life in the atmosphere of Venus,” said Dr. Thaller, in an interview with The Sun. “I never expected Venus. Venus is now one where we see something in the atmosphere that looks very much like it could be produced by bacteria,” he added.

<h2>Humans cannot survive on Venus</h2>

Venus has been often called 'Earth's twin' because of its similar structure and size. However, their conditions cannot be further apart, as astronomers say it is impossible for human beings to survive on Venus. 
 
Professor Dominic Papineau, who works as an astrobiologist at the University College of London, feels that the views of Dr. Thaller are 'difficult to realistically hypothesise'. 
 
“For life-related chemical reactions to take place, liquid water is necessary. Hence, to find extraterrestrial life, we need to find liquid water, and to find extraterrestrial fossils requires looking for sedimentary rocks that were associated with liquid water in the past,” said the professor, while speaking to MailOnline.

“This makes life on Venus today difficult to realistically hypothesise, because its surface is too hot, although Venus might have had liquid water in its past. A problem with a possible fossil record on Venus however is the widespread volcanism that appears to have covered most of the surface in the last few hundreds of millions of years,” Professor Papineau said. 
 
However, both Professor Papineau and Dr Thaller agreed that the solar system's icy moons can also be sites of potential microbial life. NASA suggested that our solar system has 290 'traditional Moons', which excludes 462 smaller asteroids and minor planets. 
 
“More likely we could find extraterrestrial life and/or fossils on Mars and in the icy moons of the outer solar system,” said Professor Papineau. 
 
“This is because liquid water exists on those planetary bodies, including within ice at the Martian south pole. Mars and icy moons also have a geological record that might preserve fossils,” he added.
