Radio signals from mobile phone towers could lead ALIENS to Earth
A new study has determined that intelligent alien beings could find Earth through mobile phone towers and the radio signals they emit.
“The Earth is already anomalously bright in the radio part of the spectrum,” said Mike Garrett, the director of Jodrell Bank Center for Astrophysics at the University of Manchester. “If the trend continues, we could become readily detectable by any advanced civilization with the right technology.”
Garrett and his colleagues used crowdsourced data to simulate the
leakage of radio signals from cell phone towers and to see how hard
these signals would be to discover from other planets. Their findings
were published February 2023 in the Monthly Notices of the Royal Astronomical Society.
The researchers found that Earth emits lots of signs of
technologically modern life, with radio leakage originating from cell
phone towers, satellite communications and internet signals. They said
these signals could reach theoretical civilizations living around
adjacent stars, including Barnard’s star – a red dwarf star located six
light-years away that may have a large, Earthlike planet orbiting it.
However, the researchers noted that these signals could only be
detected by aliens with more sensitive instruments than those found on
Earth. But as the signals get louder, even less technologically smart
aliens could possibly detect them.
“I’ve heard many colleagues suggest that Earth has become
increasingly radio quiet in recent years — a claim that I always
contested. Although it’s true, we have fewer powerful TV and radio
transmitters today, the proliferation of mobile communication systems
around the world is profound. While each system represents relatively
low radio powers individually, the integrated spectrum of billions of
these devices is substantial,” Garrett said.
Signals detectable by aliens are growing stronger
The detectability of humans is likely to rise as
Earth’s broadband systems become more powerful. According to Garrett,
current estimates suggest that humans will have more than 100,000
satellites in low Earth orbit and beyond before the end of the decade.
The findings in the study, of which Garrett is the lead author,
showed that the radiation from mobile towers is changeable in intensity
and recurrent in nature because of its non-uniform distribution on
Earth’s surface and the rotation of the planet.
The researchers determined that any nearby civilization situated
within 10 light-years of Earth and equipped with a receiving system
comparable to the Green Bank Telescope are not going to find the mobile
tower leakage from Earth. But those equipped with next-generation
telescopes like Square Kilometer Array or SKA “could do better.”
And the detectable signals from Earth will only grow stronger over
time. Future research should involve other sources of radio leakage like
individual mobile handsets, military radar, digital broadcasting and
Wi-Fi networks, they remarked.
“Every day we learn more about the characteristics of exoplanets via
space missions like Kepler and the Transiting Exoplanet Survey
Satellite, with further insights from the James Webb Space Telescope. I
believe that there’s every chance advanced civilizations are out there,
and some may be capable of observing the human-made radio leakage coming
from Earth,” said study co-author Nalini Heeralall-Issur, an
astrophysicist at the University of Mauritius.

According to NASA, a rogue, hyper-speed object, which is over
27,306 times the size of Earth, is hurtling so fast through our galaxy
that it might break free of the Milky Way.
Scientists say they have determined that the mysterious object was
cruising at a breakneck one million miles per hour when they spotted it
more than 400 light years from Earth. One light-year is equal to six
trillion miles.
Could this latest find be connected to the fake alien invasion that has long been in the pipeline?
The Mail Online reorts: While experts have not determined what the newfound celestial body is, they speculated it is a ‘brown dwarf,’ a star which is larger than a planet but lacks the mass to sustain long-term nuclear fusion in its core like Earth’s sun.
If the object confirmed as a brown dwarf, it would be first-ever to
be documented in a chaotic, hyper-speed orbit capable of breaking free
from our home galaxy.
A coalition of citizen-scientists with NASA’s ‘Backyard Worlds: Planet 9’ projectwere the first to spot the celestial body, the US space agency confirmed this week.
‘I can’t describe the level of excitement,’ German citizen-scientist Martin Kabatnik, a long-time member of NASA’s Backyard Worlds program, said in statement.
‘When I first saw how fast it was moving,’ the Nuremberg-based
researcher confessed, ‘I was convinced it must have been reported
already.’
Backyard Worlds citizen-scientists Martin Kabatnik, Thomas P. Bickle
and Dan Caselden were the first to spot this million mph object a few
years ago, earning the hyper-speed object the catalogued name CWISE
J124909.08+362116.0.
According to astronomer Dr Kyle Kremer,
who has collaborated with them on better understanding the object,
several astrophysics theories could explain how the object, CWISE J1249
for short, could have gotten to its incredible speed.
In one theory, CWISE J1249 rocketed out of a two star or binary star
system after its ‘white dwarf’ sister star died off — collapsing in an
explosive runaway nuclear fusion reaction called a supernova.
Another viable theory has it that CWISE J1249 originated inside a
tight cluster of starts called a ‘globular cluster’ where it was flung
free via the pull of a black hole.
‘When a star encounters a black hole binary,’ Dr Kremer said in a
NASA statement on the discovery, ‘the complex dynamics of this
three-body interaction can toss that star right out of the globular
cluster.’
Sławosz Uznański will be the second Pole in space and the first to fly to the International Space Station (ISS).
Uznański revealed that his mission to the ISS is planned for 2025 and will last about two weeks. He will launch from Cape Canaveral on a rocket provided by SpaceX. This journey not only represents a significant milestone for Uznański but also for Polish space exploration.
Last year, Uznański was officially selected for this mission, after which he commenced his training at the European Space Agency’s facility in Cologne, Germany. Initially planned for 2024, the mission faced delays, but new details have recently emerged on Uznański’s social media profiles.
During his two-week stay on the ISS, he will focus on Polish scientific projects and technology tests, including artificial intelligence applications in space and studies on the effects of microgravity on the human immune system.
The European Space Agency (ESA) and the Polish Space Agency (POLSA) received numerous project proposals for Uznański’s mission. Due to limited space, only seven were selected, highlighting the extensive interest and potential impact of this mission.
Uznański will travel to the ISS in SpaceX’s Crew Dragon capsule, a vehicle regularly used by NASA for transporting astronauts. The Crew Dragon will be mounted atop a Falcon 9 rocket, with the launch also set to take place at Cape Canaveral. While the exact launch date is yet to be confirmed, preparations are in full swing.
In a move to further his training, Uznański has relocated to Houston, Texas. Starting Monday, he will begin a new training phase at Axiom Space, a partner in the mission, followed by sessions at NASA and SpaceX facilities. This mission not only propels Uznański into space but also significantly advances Poland’s stature in the global aerospace sector.
