In search of alien life, astronomers focus on the Moon’s dark side

Published

Scientists are preparing to use telescopes on the far side of the moon, which could help detect signs of alien life, if it really exists, reports telegraph.co.uk.

Astronomers have long fantasized about placing observatories on the surface of the Moon, but recently the idea has been back in the spotlight as people gear up for their next mission to the Moon. Various space organizations plan to install radio telescopes.

This dark and quiet place is ideal for receiving weak, very low frequency radio waves left over from the dark ages of the universe. This is because in this place they are protected from radio communications from Earth. Experts say that these conditions make it possible to find something “extraordinary”.

“This is something that has been around for a long time as an idea. For the first time, agencies are starting to take this very seriously. It becomes something that is considered trustworthy and important, and something that can actually happen. We could do some extraordinary science,” said James Carpenter of ESA’s Human and Robot Research Program.

This comes after the successful launch of NASA’s Artemis, which paved the way for humanity’s return to the Moon by the end of the decade.

“There is a huge interest in projects on the Moon, and for cosmology, this may allow us to reach some of the extreme limits that we dream of. The moon is the most radio-quiet sky in the inner solar system, ” explained Professor Joseph Silka from the Paris Astrophysical Institute.

Back in 2021, NASA announced a proposal for the Lunar Crater Radio Telescope, an ultra-longwave radio telescope on the far side of the Moon.

NASA has said it will be much more effective at learning about the Dark Ages of the universe than ground-based or orbiting telescopes. The dark ages of the universe refer to the period of its early history after the Big Bang, but before the appearance of the first stars.

The team behind the planned telescope is about to deploy space robots to build a half-mile (one kilometer) wide radio telescope in one of several proposed craters on the far side of the surface. The telescope itself will have a wire mesh that must withstand temperatures ranging from -173 degrees Celsius to 127 degrees.

“There is a whole region of the universe that we simply cannot see. The development of this concept can lead to significant breakthroughs, especially in the field of deployment technologies and the use of robots to build giant structures beyond the Earth.

“I am proud to work with this diverse team of experts who are inspiring the world to think about the big ideas that groundbreaking discoveries can make about the universe we live in,” the researchers explained.

But radio telescopes may not only provide clues to the origin of the universe, but also offer the potential to search for extraterrestrial life.

That’s because, if it’s really there, telescopes could detect regular and continuous pulses of energy from outside the universe that could point to alien technology.

Using a radio telescope on the far side of the Moon offers an advantage in this regard because radio signals are often limited by interference from signals on Earth.

‘October Surprise’: Russia To Launch Nukes in Space

Published

The ‘national security threat’ announced on Wednesday is
about Russia planning to launch nuclear weapons in space, causing some
to speculate whether it’s really an election year ploy.

The panic began when House Intelligence Committee Chair Mike Turner
(R-Ohio) asked President Biden to declassify information about a
“serious national security threat”.

Modernity.news reports: The weapon would reportedly be designed to be used to take out satellites.

Speaker Mike Johnson (R-La.) responded by telling reporters he wanted “to assure the American people, there is no need for public alarm.”

The big, scary threat is serious business and involves a space-based nuke controlled by evil dictator Putin, but it’s also “not an immediate crisis,” according to what three members of the U.S. House Intelligence Committee have told Politico.

Okay, then. Just for election season, is it?

Zero Hedge reports: “So, the question is – was this:

a) a distraction from Biden’s broken brain, or

2) a last desperate attempt to get more funding for anything-but-the-US-border, or

iii) a path to pitching Putin as the uber-bad-guy again after his interview with Tucker Carlson.”

Just by coincidence, Mike Turner recently returned from Ukraine having lobbied for billions more in weapons and aid for Zelensky’s government.

Some questioned the timing, suggesting it might all be a deep state plot to keep American voters afraid when they hit the ballot box.

Speculation will now rage as to whether this is “the event,” real or imagined, that billionaires and elitists the world over have been building underground survival bunkers in preparation for.

Earth has built-in protection from asteroids

Published

Asteroids are not just wandering space rocks, but a potential threat
to Earth. But what if the Earth already has its own built-in defenses
against them? Recent research published on the preprint server arXiv puts forward an unusual theory: Earth’s gravitational forces may serve as its secret shield against asteroids.

Our
planet uses powerful gravitational interactions with other celestial
bodies to break apart asteroids that approach it. These tidal forces,
akin to those that explain Earth’s tides caused by the Moon, can be so
intense that objects undergo tidal disruption, causing them to be torn
apart.

Observations of fragments of Comet Shoemaker-Levy 9 after
its collision with Jupiter in 1994 provided the first confirmation of
this phenomenon. However, for decades astronomers have been looking for
evidence that Earth or other terrestrial planets could have a similar
effect on asteroids and comets.

Planetary scientist Mikael Granvik
from the Swedish University of Technology, Luleå, led the research that
came closer to solving the above phenomenon.

His
discovery is linked to the search for gravitationally disrupted
near-Earth asteroids (NEAS), and provides compelling evidence that our
planet’s gravitational forces are not just an abstract concept, but a
factor capable of breaking asteroids into small pieces.

Based on
modeling of asteroid trajectories, Grunwick and colleague Kevin Walsh of
the Southwest Research Institute found that collisions with rocky
planets can cause asteroids to lose a significant portion of their mass,
turning them into debris streams.

New data shows that small
asteroid fragments, while not posing a threat to life on the planet, may
nevertheless increase the likelihood of local collisions like those
that occurred in Tunguska and Chelyabinsk.

Granwick assures that
asteroids smaller than 1 km in diameter are not a critical threat, but
increase the likelihood of incidents. However, it is worth remembering
the additional risks that may arise due to the formation of new debris
clouds.
