NASA scientist says aliens or other life will soon be found on Mars
NASA scientists have been searching for extraterrestrial life for a long time. Moreover, the space agency has never denied this, and this is enough to discuss the possibility of the existence of extraterrestrial beings outside the Earth in any form, from micro to macro.
The controversy arose when a couple of years ago, retired NASA Chief Scientist James L. Green spoke about Mars and the alleged extraterrestrial life on it.
Before moving on to Dr. Green’s statement, it should be known that NASA has acknowledged that there may be interference from alien civilizations in the history of the Earth. In 2014, NASA published a book titled Archeology, Anthropology and Interstellar Space which looks at extraterrestrial interference in human history. It notes the possibility that some of the rock art on Earth may be of alien origin. It was edited by Douglas Wakoh, director of the Search for Extraterrestrial Intelligence (SETI) Division.
Also, in fact, it would take only 10,000 years for the traces of human presence to disappear from the planet, which is very short period compared to the age of the Earth.
If such a civilization had once existed, then its traces would not be so obvious – given that more than 4 billion years of the Earth is a sufficiently wide range for the evolution (and extinction) of intelligent life.
In 2019, retired NASA Chief Science Officer Dr. Jim Green made several statements that caused a lot of controversy. The expert believes that, most likely, the European Space Agency (ESA) has already discovered evidence of extraterrestrial life on Mars. The fact is, Dr. Green is convinced, that humanity is simply not ready for such information.

In the summer of 2020, two rovers from NASA and the European Space Agency (ESA) traveled to Mars to perform horizontal drilling in rock, hoping to find evidence of living organisms.
He assured that evidence of extraterrestrial existence on Mars was obtained, at the latest, in mid-2021. However, it will take humanity much longer to come to terms with the fact that life still exists outside the Earth.
Has Perseverance found life on the surface of Mars?
NASA’s Perseverance rover is currently exploring two very different geological sites at the bottom of Jezero Crater since it landed on February 18, 2021. The rover has found new evidence of ancient hot magma and water. He also discovered ancient organic molecules preserved in rocks and dust.
The Perseverance rover used the Raman & Luminescence for Organics & Chemicals (SHERLOC) instrument to detect them. Organic matter is an intriguing discovery as they are the building blocks of life.
However, both biological and non-biological processes can create organics. Whether these particular organic substances come from once-living organisms or not is something that scientists have yet to determine. In addition, this is not the first time that the rover has detected organic matter on Mars.
Has NASA already found aliens on Mars?
Before the launch, Dr Green said: These missions are humanity’s best chance ever to answer the question: “Are we alone in the universe?” Jim Green was instrumental in both missions. He added that “there is a real possibility that one or both will be successful.”
However, this will have far-reaching consequences, and he believes that the Earth is not ready for them.
“It will be a revolution. This will start a whole new way of thinking. I don’t think we are ready for such results,” Green said.
A study published in 2020 shows that planets previously thought to be uninhabitable may once have had suitable conditions for life. Researchers have discovered the chemical phosphine in the dense atmosphere of Venus.
After careful analysis, scientists argue that the only explanation for the source of the chemical is something alive.
Dr. Green said one of the promising signs of life on Mars is that every summer on the planet, the amount of methane present on the surface increases dramatically. The Curiosity rover on Mars also detected molecular oxygen, which increases by up to 30 percent each spring and summer before falling again in the fall.
“It tells us that life can be deep below the surface in the summer. The heat of the soil and therefore is weakened so that the methane can seep out. We have all sorts of indirect observations that perhaps there is microbial life on Mars too,” he explained.
It is likely that life on Mars and Venus can still be sustained underground, and in order to make the surface habitable, Dr. Green proposed terraforming both planets.
He said it was possible to terraform Mars by placing a giant magnetic shield between the planet and the sun, which would prevent the Sun from stripping it of its atmosphere, allowing the planet to trap more heat and warm the climate to make it habitable.
Alien space debris stuck in Earth’s orbit, researchers say
Recently, a group of experts from Harvard University, led by physics
professor Avi Loeb, announced the possible presence of alien space
debris in Earth’s orbit, reports the Daily Star.
space research expert Professor Loeb is confident that the discovery of
such “interstellar objects could help expand our knowledge of possible
alien civilizations and technologies. A team of scientists is conducting
research to confirm that some of the objects in our orbit may be
connected to other star systems.
During an interview with Live
Science, Professor Loeb explained that these objects could enter the
solar system from interstellar space, defying Jupiter’s gravitational
pull and occupying limited orbits around the sun.
Some of them may
have technological origins similar to the probes sent by mankind into
interstellar space, such as Voyager 1 and Voyager 2, Pioneer 10 and 11
and New Horizons.
despite these interesting assumptions, Professor Loeb did not specify
what specific objects he was talking about. In his research report, he
notes that there could be “a significant number” of potentially
detectable objects in Earth’s orbit.
To confirm their assumptions,
the team of scientists uses computer simulations and the Vera Rubin
Observatory (Chile) with a high-resolution camera of 3.2 billion pixels.
This will allow for regular observations of the Southern sky and the
possibility of detecting several captured objects about the size of a
It is assumed that these interstellar objects passed through the
boundaries of the solar system and may carry unique information about
other civilizations and their technologies. If we could confirm the
origin of these objects, the mysteries that open before us, this would
be a real breakthrough in space exploration.
expresses hope that the new research will not only help expand our
knowledge of extraterrestrial technologies, but may also lead to the
discovery of new alien civilizations . Answers to such questions can be
of global significance and influence our understanding of the place of
mankind in the Universe.
while there are still many questions and assumptions, the study by
Professor Loeb and his team opens a new chapter in space exploration.
Each new discovery can be the key to deciphering the mysteries of the
cosmos and the possibility of encountering alien life forms.
Betelgeuse is acting strange again
Betelgeuse, a red giant on the brink of death, continues to show
unusual behavior. After the Great Blackout, which occurred in late 2019
and early 2020, the star became unusually bright. It is now the seventh
brightest star in the sky, while it normally ranks tenth. This has led
to speculation that Betelgeuse is preparing to explode in a
spectacularly large supernova.
However, scientists believe it’s too early to tell, and it’s likely
that this behavior is due to ongoing fluctuations after the Great
Blackout of 2019, and the star will return to normal within a decade.
Betelgeuse is one of the most interesting stars in the sky. It is
about 700 light-years from Earth and is a red giant in the last stage of
its life. It is also an unusual star for a red giant because it was
previously a monster blue-white O-type star, the most massive class of
Betelgeuse has changed its spectral type because it has almost
exhausted its hydrogen reserves. It now burns helium into carbon and
oxygen and has expanded to a gigantic size: about 764 times the size of
the Sun and about 16.5 to 19 times its mass.
Eventually it will run out of fuel to burn, become a supernova, eject
its outer material, and its core will collapse into a neutron star.
Before the Great Blackout, Betelgeuse also had periodic fluctuations
in brightness. The longest of these cycles is about 5.9 years and the
other is 400 days. But it seems that the Great Blackout caused changes
in these oscillations.
A new paper by astrophysicist Morgan McLeod of the
Harvard-Smithsonian Center for Astrophysics has shown that the 400-day
cycle appears to have been halved. This pulsational cycle is probably
caused by expansion and contraction within the star. According to
simulations carried out by MacLeod and his colleagues, the convective
flow inside Betelgeuse may have risen and become material that separates
from the star.
