Are Aliens on Earth? This is the explanation of NASA Scientists

TEMPO.CO, Jakarta – The eternal question that lurks in the mind of every space fan is “is there life beyond Earth (aliens)?” Despite many space expeditions, so far the United States Aeronautics and Space Administration or NASA still have not found any traces of life beyond Earth.

Every now and then we also hear information about unidentified flying objects (UFOs) seen in some parts of the world. Most of the time, these sightings turn out to be fakes, and the others remain a mystery. Considering that the universe is infinite, the possibilities of finding life beyond Earth are wide open.

A NASA scientist has been trying to answer questions about aliens and whether they exist. In a video on NASA’s Instagram page, Lindsay Hays, an astrobiologist, explains that this is a very interesting question. A question that scientists have been trying to understand and explore for a very long time, but they haven’t been able to find life on any other planet.

“NASA continues to search for signs of life beyond Earth. We have sent five rover and four landers to Mars,” he said in a video uploaded on Saturday, April 11, 2021.

In the one minute and thirty-two second video, Hays added, NASA has equipped the orbiter with a very high-resolution camera, which continues to observe the Martian surface. However, only a small part of Mars has been explored so far.

The more they explore the place, the more they learn about the different environments for which life exists. “So we can’t say yet whether aliens exist or not,” Hays said.

Hays later quotes American astronomer and best-selling author Carl Sagan, as saying that the universe is a pretty big place. “If it’s just us, it seems like a terrible waste of space,” he says in the video, which has now been viewed more than a million times, and has more than 2,000 comments.

The NASA scientist promised to continue to search for life on other planets. Several Instagram users commented on NASA’s upload, some even claiming that extraterrestrial life exists.

“Of course they are! They exist!” tweeted a user named @griffith.david1. While another user named @sputniksworld commented: “If they exist, we better hope they are friendly.”
