Could aliens be watching us? It’s more likely than you think
A recent report by US Pentagon officials suggests that alien civilizations may be exploring our solar system with small probes that could gather and transmit data.
The report, co-authored by Dr. Sean Kirkpatrick, the director of the US Department of Defense’s All-domain Anomaly Resolution Office (AARO) and Avi Loeb, former chair of Harvard University’s Department of Astronomy, was published on March 7 and examines the physical constraints of unidentified aerial phenomena, reports jpost.com.
The authors propose that extraterrestrials may be using what they call “dandelion seeds”, which are very small spacecraft that can collect and transmit information, similar to NASA’s probes.
“An artificial object carried on a small aircraft that will release several small tracking devices may visit or has already visited earth,” the authors wrote.
“The aircraft can rely on the gravitational force of the sun, or move on its own.”
The report cites two examples of possible alien probes that were detected by NASA’s telescopes in Hawai’i. The first one is “Oumuamua”, a cylindrical object that was observed in October 2017 and was believed by some to be artificial.
The second one is an object approximately one meter in length that collided with the Earth six months before the appearance of “Oumuamua”.
The report claims that such objects could likely reach Earth without being detected by astronomers as they would be too small to reflect enough sunlight to see them with most of NASA’s telescope technology.
“All these [potential spy devices] could be equipped with a parachute with a large area-to-mass ratio, slowing their entry to Earth’s atmosphere,” wrote the report authors.
“This would prevent [the device from catching on] fire and [allow them] to pursue their targets wherever they land.”
The authors speculate that aliens may be interested in rocky planets with liquid water. They also note that any alien civilization that sends probes our way may no longer exist at all.
Most of the stars in the galaxy were formed billions of years before our sun. A habitable planet with intelligent life could have sent these spy devices long before the Earth was formed and they may still be roaming around our solar system.
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.
