In the wake of mankind’s latest advances in science, space and planetary research, scientists are coming to conclusions that would have been unimaginable years ago.
India has reached the lunar south pole for the first time, NASA is going to study the surface of Venus, and Neptune’s dark spots have been examined.
Thanks to all these advances, there are scientists, even from NASA, who already believe that extraterrestrial life exists, as is the case of Michelle Thaller.

Covering the subject of deep space at an exhibition in New York, the doctor wanted to answer the question that every human being has ever asked: is there extraterrestrial life, to which the scientist answered without any doubt.
“Definitely, I believe we will find life on another planet,” Thaller explained to The US Sun.
She believes that within the galaxy where we are positioned, there is a good chance of finding the extraterrestrial life we so desperately want to know about.
“I think in our own Solar System we’re pretty close to that, but again, we don’t have that 100 percent,” she continued.
“According to our research on neighboring planets, the red planet Mars was once like Earth, only it currently has no magnetic field and no greenhouse gases, so it has no liquid state, which means it cannot support life.”
Mars and Venus, potential planets with life in their past
Mars more than 4 billion years ago was liquid, which meant that its temperatures were warmer. NASA is analyzing the red planet using the Curiosity rover and there they found data on amino acids.
“Finding certain amino acids on Mars would be considered a potential sign of ancient Martian life because they are widely used by terrestrial life as a building block for proteins,” the NASA scientist posted in a blog on their website.
“Proteins are essential for life, as they are used to produce enzymes that accelerate or regulate chemical reactions and to form structures.”
Venus is also a rocky planet, like Earth and Mars. The doctor has some hope for it, saying they see “something in its atmosphere that looks a lot like what bacteria might have produced.”
