Space pollution: Astronomers call on world governments to intervene on 5G satellites



(Planet today) A group of professional astronomers has made an international appeal to put an end to the 5G satellite madness in order to protect the astronomical sky.

Their formal request follows many of the concerns previously voiced by the International Astronomical Union as well as other institutions. They argue that sky degradation is coming from not just light pollution in the sky around cities; it is increasingly coming from artificial satellite fleets that create bright parallel streaks and trails, obscuring important views of the universe.

Astronomers worry the earth could soon be blanketed by tens of thousands of satellites, handily outnumbering the roughly 9000 stars currently visible to the unaided human eye and adversely impacting their ability to make astronomical observations, which in the past have led to incredible progress in our scientific understanding of how the laws of nature work.

SpaceX has already sent 180 small satellites into orbit and intends to fill the sky with around 42,000 satellites overall. When you add in other telecommunications space projects that are expected to launch 5G satellites, such as those from Facebook, Amazon, OneWeb, Telesat, Roscosmos of Russia, and the Chinese Aerospace Science and Industry Corp, there could soon be more than 50,000 small satellites orbiting our planet for telecommunication purposes.

There is a lot to worry about here, with these small, mass-produced satellites orbiting very close to the Earth, which makes them brighter and more visible in the night sky. For example, the satellites launched by SpaceX are now greater than 99% of all the objects visible by the earth orbit.

University of California Davis physicist and astronomer Tony Tyson said that when there are 50,000 satellites in the sky, “you’ll see the sky crawling,” adding that “every square degree will have something crawling in it.”

Space debris and 5G radiation are major concerns

Not only will this hamper our view of the universe, but it will create a greater amount of space debris. When a satellite breaks down in space, it remains out there as space junk until gravity brings it back down to Earth. While it is up in space in the form of debris, it could potentially collide with other objects and create serious problems.

In addition to threatening scientific advances and creating dangerous space debris, many of these satellites are essentially carpet-bombing our planet with 5G radiation, which means that even those who opt out of using the dangerous technology will essentially have nowhere to go to avoid exposure.

Countless studies have shown that Wi-Fi radiation can have devastating effects on our brain and our overall health. Children are particularly vulnerable to this exposure because their bodies are still developing. 5G makes use of thousands of mini antennas forming beams that don’t weaken across broad distances the way that those of 4G do, which means that humanity is at significant risk.

The electromagnetic radiation changes that cell phone use causes in the brain are believed to be one of the factors behind the fact that we now have the highest suicide rate since the Second World War. It may also explain why children who are just 9 and 10 years old have brains that resemble those of elderly senile people in scans.

Experts like Claire Edwards believe that the race for 5G and the push for a fast rollout comes from a desire to have the technology in place before people fully understand the dangers of it and have the time to organize and block it. After all, once these tens of thousands of satellites are already orbiting the Earth, there won’t be much that people can do to stop it.

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
football field.

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.

Professor Loeb
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.
