Scientists Are Puzzled By Mysterious Signals From Two Planets At Once

Published

on

Both worlds are similar to the Earth, revolve around sun-like stars and are in the same constellation at about the same distance from us.

Green Bank radio telescope is located in the eastern United States in the so-called radio silence zone, that is, in an area where very little use is made of anything that emits radio waves.

If, for example, emergency services need to notify the population about something, they must warn the observatory. Green Bank is one of the main tools of the SETI project: Search for Extraterrestrial Intelligence. A full-turning 100-meter dish can be directed to any point in the sky, more precisely, to that part of the celestial sphere that is above it.

A group of scientists involved in SETI received a six-hour observation window several years ago on March 25, 2018. The experts decided during this time to listen to the exoplanets, which at that moment will pass through the disks of their stars, this is called a transit.

There were hundreds of such planets, but only a few of them had to be chosen, which are closer to us and to each other in the sky. Recall that today more than five thousand exoplanets have been officially confirmed, many of them have a year, that is, the period of rotation around the star, is only a few days.

That is, every few days they transit through the disks of their parent stars. In this case, they settled on 12 planets in the constellation Cygnus.

In terms of size, the selected planets are either about the size of the Earth, or one and a half of the Earth, and one is 12 times larger than the Earth, that is, even larger than Jupiter. And this is really a gas giant, it does not have a solid surface, but, on the other hand, it may well have solid satellites, like our Jupiter.

These exoplanets follow the disk of their star (some in forty minutes, others in almost four hours), but scientists observed each transit for only a few minutes.

What scientists want to hear: First, they need a radio frequency of about 1420 megahertz. The fact is that it is at this frequency that hydrogen, the most common element in the universe, “broadcasts”. In addition, at this frequency, the background general galactic radio noise is almost inaudible.

Therefore, astrophysicists reasoned that it would be most logical for a hypothetical extraterrestrial civilization to choose just such a frequency. Secondly, it is much easier to catch the signal of an extraterrestrial civilization if it is narrow-band, again, easily distinguishable against the general background.

Twelve planets listened in the range from 1100 to 1900 megahertz. It is interesting that the calculation was that if there is someone reasonable there, then they know about us and purposefully send a signal to us.

So, from their point of view, it is best to signal when their planet in our telescopes is clearly in the middle of the star’s disk, because at that moment it looks exactly at the Earth. And at the same time, astrophysicists emphasize that if we catch a meaningful signal from them, then their transmitter is definitely 60 times more powerful than the one on the famous Arecibo telescope in Puerto Rico.

Recall that earthlings sent messages to brothers in mind, including from Arecibo and from the RT-70 telescope in Evpatoria. As a result, most of all, what was needed was heard from two planets.

One of them – Kepler-1332 b – weighs like two and a half Earths, the other – Kepler-842 b – is three times as massive as our planet. Both are located at a distance of about 1700 light years from us. Both are found near stars slightly smaller than the Sun.

One star is a little hotter than our star, the other is colder and dimmer – an orange dwarf. In fact, it’s hard to imagine how heat-resistant and fire-resistant intelligent life must be there: these worlds are several times closer to their stars than Mercury is to the Sun.

Nevertheless, the signals from them came at just about the right frequency: 1749 megahertz and 1040-1438 megahertz, respectively. True, they turned out to be quite broadband, but, perhaps, it is all the more surprising that we caught them.

In addition, scientists say that you still need to make allowances for the fact that others can reason and develop technology in a different way. And the most curious thing: both signals were received just when the planets were at the very center of the star’s disk.

Life on a hot planet can be a daunting prospect. With temperatures soaring to levels that can make it difficult for life to exist, the notion of living on a planet where the temperatures are so high seems like an impossibility. But, in reality, life can find ways to survive the heat, and even thrive in such conditions.

One way life can survive on a hot planet is through the process of adaptation. Adaptation is the ability of a species to evolve and change in order to survive in a new environment. By evolving certain abilities, such as a thicker skin, stronger claws or wings that enable them to soar in the heat, these species have the ability to survive in the hot and hostile atmosphere of a planet.

Another way life can survive on a hot planet is through the use of hibernation. Hibernation is a state of inactivity that animals enter in order to conserve energy and survive in extreme temperatures. By entering this state of rest, animals can survive temperatures that would be too hot for them to handle while they are active. This process of hibernation is common in desert animals, and could be a potential way of life on hot planets.

Finally, life on a hot planet could be possible through the use of technology. While the temperatures on hot planets may be too extreme for any living species, the use of technology could provide the means for life to exist. Robots and machines could be used to explore the planet and collect data, while satellites and communication devices could be used to connect inhabitants of the hot planet with the outside world.

Overall, the idea of life existing on a hot planet is certainly not impossible. Through natural adaptation, hibernation, and the use of technology, life could certainly have a chance to exist and even thrive in such extreme climates.

“Alien bases” may be hiding off the coast of Alaska, researchers say

Published

By

An organization of civilian volunteers dedicated to the study of
unidentified flying objects (UFOs) has issued a statement based on
decades of studying eyewitness reports. According to Mutual UFO Network,
“alien bases” may be hiding off the coast of Alaska, reports the-sun.com.

Researchers
say the deep waters in this region may hold something surprising. After
analyzing reports from the ship’s crew from 1945, they hypothesized
that alien objects could be lurking underwater, off the coast of the
state.

Alleged sightings of alien spacecraft nearly 80 years ago
have become a key point in research. Members of the organization believe
that UFOs move over water and may have “bases.”

Researchers
allege crew members on a U.S. Army transporter ship sailing past Island
Adak saw a massive UFO sized 150 to 200 feet emerge from the water.
Although these reports are nowhere to be found, UFO enthusiasts believe
the unidentified flying vehicles likely were used to commute to
different supposed alien bases hiding in the deep waters.

As
the “secret reports” of the sailors aren’t available, investigators
have taken it upon themselves to unravel the mystery surrounding the
unidentified flying objects and they believe the ocean has alien bases
that humans aren’t aware of.

Enthusiasts claim that UFOs may be
using “underwater networks” or wormholes as superhighways to travel
between points in the universe. UFO researcher Johnny Enoch added that
such objects could serve as a vehicle for aliens.

There are also
theories that other places on Earth could serve as bases for alien life.
A mountain in Seoul, South Korea is believed to be hiding a UFO,
according to Dr. Steven Greer.

An episode of the series “The
Alaska Triangle” features satellite imagery that claims to show one of
the “alien bases” in the Pacific Ocean off the coast of California.

Meanwhile,
another researcher featured in the program showed markings from the sea
bed that she claimed could have been roadways for aliens.

While
the mysteries of the ocean remain unsolved, researchers continue their
search, trying to unravel the mystery of what may be hiding in the
depths of the waters off the coast of Alaska.

Enormous City-Size Comet Racing Towards Earth Grows ‘Devil Horns’ After Massive Eruption

Published

By


A volcanic comet the size of a mid-sized US city has
violently exploded for the second time in four months as it continues
racing toward the earth. And following the massive eruption, the cloud
of ice and gas sprouted what looked like a pair of gigantic devil horns.

The city-sized comet, named 12P/Pons-Brooks, is a cryovolcanic — or
cold volcano — comet. It has a solid nucleus, with an estimated diameter
of 18.6 miles, and is filled with a mix of ice, dust and gas known as
cryomagma. The nucleus is surrounded by a fuzzy cloud of gas called a
coma, which leaks out of the comet’s interior.

When solar radiation heats the comet’s insides, the pressure builds up
and the comet violently explodes, ejaculating its ice-cold innards into
space through seeping cracks in the nucleus’s shell.

Live Science report:
On Oct. 5, astronomers detected a large outburst from 12P, after the
comet became dozens of times brighter due to the extra light reflecting
from its expanded coma, according to the British Astronomical Association (BAA), which has been closely monitoring the comet 

Over the next few days, the comet’s coma expanded further and developed its “peculiar horns,” Spaceweather.com
reported. Some experts joked that the irregular shape of the coma also
makes the comet look like a science fiction spaceship, such as the
Millennium Falcon from Star Wars.

The unusual shape of the comet’s coma is likely due to an irregularity in the shape of 12P’s nucleus, Richard Miles, a BAA astronomer, told Live Science after the comet’s previous eruption.
The outflowing gas is likely being partially obstructed by a notch
sticking out on the nucleus, Miles said. As the gas continues to expand
away from the comet, the irregularity in the coma’s shape becomes more
defined and noticeable, he added.

12P is currently hurtling toward the inner solar system, where it
will be slingshotted around the sun on its highly elliptical 71-year
orbit around our home star — similar to the green comet Nishimura, which
pulled off a near-identical maneuver on Sept. 17

12P will reach its closest point to Earth on April 21, 2024, when it
may become visible to the naked eye before being catapulted back toward
the outer solar system. It will not return until 2095.

This is the second time 12P has sprouted its horns this year. On July
20, astronomers witnessed the comet blow its top for the first time in
69 years (mainly due to its outbursts being less frequent and harder to
spot during the rest of its orbit). On that occasion, 12P’s coma grew to
around 143,000 miles (230,000 km), which is around 7,000 times wider
than the comet’s nucleus.

It is unclear how large the coma grew during the most recent
eruption, but there are signs the outburst was “twice as intense” as the
previous one, the BAA noted. By now, the coma has likely shrunk back to
near its normal size.

As 12P continues to race toward the sun, there is a high probability
that we will witness several more major eruptions. It is possible that
those eruptions will be even bigger than the most recent one as the
comet soaks up more solar radiation, according to Spaceweather.com.

But 12P is not the only volcanic comet that astronomers are currently
monitoring: 29P/Schwassmann-Wachmann (29P) — the most volatile volcanic
comet in the solar system — has also had several noticeable eruptions
in the last year.

In December 2022, 29P experienced its largest eruption in around 12 years, which sprayed around 1 million tons of cryomagma into space. And in April this year, for the first time ever, scientists accurately predicted one of 29P’s eruptions before it actually happened, thanks to a slight increase in the comet’s brightness in the lead-up to the icy explosion.
