The scientist suggested when humanity will find extraterrestrial life
(Planet Today) Astrophysicist Sasha Quanz, an astrophysicist at Switzerland’s federal technology institute ETH Zurich, said that new technological projects are being created that will answer the question of whether we are alone in the universe.
Researchers have been looking for extraterrestrial civilizations and studying outer space for decades. But the question of whether we are alone in the universe or whether life exists somewhere else remains open.
Astrophysicist Sasha Quanz believes that humanity will find representatives of other planets, and this will happen soon, reports space.com.
According to the scientist, new technological projects are now being created in the world that can enhance the search for extraterrestrial life in our galaxy. And with their help, humanity will discover aliens over the next 25 years.
He noted that at the moment, astronomers have discovered more than 5 thousand planets like Earth outside the solar system.
“In 1995, my colleague [and Noble Prize laureate] Didier Queloz discovered the first planet outside our solar system,” Quanz said during the briefing. “Today, more than 5,000 exoplanets are known and we are discovering them on a daily basis.”
There are many more exoplanets waiting to be discovered given that astronomers believe that each of the more than 100 billion stars in the Milky Way galaxy has at least one companion planet.
That makes for an enormous number of exoplanets, many of which, Quanz added, are just like Earth and at the right distance from their host stars to enable conditions for life, such as the presence of liquid water.
“What we do not know is if these terrestrial planets have atmospheres and what these atmospheres are made of,” Quanz said. “We need to investigate the atmospheres of these planets. We need an observational approach that would allow us to take pictures of these planets.”
Quantz added that while ambitious, the 25 year timeframe he set himself for finding life outside the solar system is not “unrealistic.”
“There’s no guarantee for success. But we’re going to learn other things on the way,” he said.
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.
