Planets that are deliberately hidden from humans

Planets that are deliberately hidden from humans 86

It is hard to believe that during the 13 billion years of the existence of the Universe in space no intelligent civilization has developed. So why haven’t we met anyone yet?

Is humanity the only rational race – this is the question hundreds of scientists are asking. The answer to it was never received, although we put our own telescopes into orbit and looked into the most remote corners of the Universe. Are there really no aliens or do they just not want to be found?

Fermi paradox

There are trillions of stars in our galaxy. Studies show that many of them have planets, with 1-2 even in a potential habitat zone. Thus, in the course of simple calculations, astronomers determined that only in the Milky Way there are about 17 billion planets where life could have originated.

Based on all this, physicist Enrico Fermi formulated his paradox. The scientist said that in this situation, either our understanding of nature or the methods of observation are fundamentally wrong. Have all the time not even some traces of the vital activity of other races — radio waves or other radiation — have reached us?

It would be foolish to say that intelligent life really does not exist. Simple math says the opposite. Talking about underdeveloped observing systems is also inappropriate – we observe the cosmos at different periods of its life and literally study the history of the Galaxy . But even there is no sign of the existence of other civilizations. Are we under the dome of ignorance?

Are they hiding from us?

David Kipping of Harvard and Alex Tichy of Columbia University offer their explanation of the problem. According to a published article, alien civilizations are simply hiding from us. They have technologies that can literally “wipe” the emitted radiation in almost all spectra. And this is not to mention the concealment of life on the planets from prying eyes.

Another theory suggests that the Milky Way already has a highly developed cosmic community . It strictly controls any potentially inhabited planets with intelligent life and hides the real state of affairs from underdeveloped civilizations. Among them is humanity. This explains why all our searches are so unsuccessful.

The question remains open, why hide their existence from others? There are several options for this. Aliens can do this for their own safety. During its short history, mankind has managed to conduct hundreds of wars and the state of affairs does not change much, although the scale of conflicts has slightly decreased.

Now imagine wars on a cosmic scale . In such matters, hiding the location of one’s home planet or colonies is vital.

It is possible that they are hiding the truth from us for their own benefit. What will happen to society if reliable information appears about the existence of another highly developed race? Fear will envelop people, because we will face an adversary who can erase all of humanity with the click of a finger (or tentacle). Ignorance is calm.

In any case, it will not last forever. With the help of more powerful telescopes or space travel, humanity will answer the most important question – are we alone in the universe.

In December, Earth’s inhabitants will be able to see a rare cosmic phenomenon

In December, Earth's inhabitants will be able to see a rare cosmic phenomenon 99

At the end of the year, astronomers expect to see a rare cosmic phenomenon dubbed the “Christmas star” in the sky. It will be caused by the fact that Saturn and Jupiter come close to each other at a minimum distance and almost collide to become one super-bright point of light.

These two planets became one straight line in the solar system a few weeks ago, but at the end of December they will be on it for observers from Earth. This will happen on December 21, 2020, on the day of the winter solstice, when the daylight hours are the shortest and the night is the longest. Jupiter and Saturn will look like a “double planet” for the first time since the Middle Ages, Forbes writes.

“The conjunctions of the two planets are extremely rare, but this particular conjunction is especially rare because the planets will be very close to each other,” Patrick Hartigan, astronomer at Rice University, USA said. “In order to observe a closer conjunction of these planets in the night sky, we would have to return on March 4, 1226.”

It is noted that the unusual celestial phenomenon can be observed from anywhere on the planet. The main thing is that the sky is clear. The “Christmas Star” can be seen in the western sky about an hour after sunset when viewed from the northern hemisphere.

“On the evening of their closest approach, December 21, they will appear as a twin planet, separated by less than 1/5 the diameter of the full moon,” Hartigan said. “For most amateur astronomers looking at the night sky through a telescope, both planets and several of their largest satellites will be in the same field of view this evening.”

Those who want to see Jupiter and Saturn converge in the sky as close, but will be higher above the horizon, will have to wait until March 15, 2080, Hartigan said. After that, a similar configuration for this planetary pair will not be observed until 2400.

Astronomers are already preparing equipment to analyze in detail the upcoming event. Everything is very serious, because the second such rapprochement between Jupiter and Saturn cannot be expected.

Of course, there will not be a collision of planets. You just get the impression that something terrible is about to happen in the solar system. Astronomers have assured that there is no reason to worry.

Is the “Christmas Star” an omen of things to come? Mark your calendars!

A giant asteroid worth $ 17.4 billion is approaching Earth

A giant asteroid worth $ 17.4 billion is approaching Earth 101

NASA announced the imminent flight of a potentially dangerous asteroid will pass the Earth. The website of the Center for the Study of Near-Earth Objects says that a celestial body ranging in size from 370 to 820 meters will approach the planet on November 29.

The asteroid, consisting of nickel, iron and cobalt, is approaching the Earth. The cost of minerals in its composition reaches $ 17.4 billion, with reference to the Asterank database, which contains data on 600 thousand asteroids.

The distance between the asteroid 153201 (2000 WO107) and the Earth will be more than 4 million kilometers, the Space Reference specified with reference to NASA data. It is noted that the distance from the Earth to the Moon is 10 times less, and the asteroid is considered dangerous because it crosses the orbit of our planet.

According to the NASA Center for the Study of Near-Earth Objects, the celestial body will approach the Earth on November 29. 

It is noted that this time the asteroid does not pose a threat to the planet, however, it belongs to the group of potentially dangerous ones, since its trajectory crosses the Earth’s orbit.

Intrusive buzzing. The Perseverance rover recorded the space sounds of its flight to Mars

Intrusive buzzing. The Perseverance rover recorded the space sounds of its flight to Mars 102

NASA’s new rover is equipped with a microphone to record sounds during landing on the Red Planet.

NASA’s Perseverance rover, which is en route to Mars, has recorded its flight to the planet.

The new rover is equipped with a microphone designed to record sound when entering the atmosphere, descent and landing. The device should arrive on the Red Planet in February 2021.

But before the rover reached its destination, NASA’s Jet Propulsion Laboratory (JPL) released an audio file recording what the rover “hears” during its interplanetary voyage.

The 60-second recording, posted on SoundCloud, was captured on Oct.19 while checking the rover’s EDL and microphone system.

Experts explain that the buzzing sound comes from a pump that pumps fluid to regulate the rover’s temperature.

NASA compares the new hit for your playlist to the noise you hear on wired headphones when the wire rubs against your clothing. It was these mechanical vibrations that the Perseverance microphone picked up.

“Located at the rear of the starboard side of the Perseverance, the pump is part of the unit’s heat system that maintains operating temperatures for the equipment, even in the coldest locations,” JPL said in a statement.

“I apologize to the person who came up with the slogan for the film” Alien “(” No one in space will hear your scream “- ed.), Perhaps no one will hear the scream, but perhaps a pump to remove heat will be heard,” says a leading engineer at JPL Dave Gruel.

He added that the microphone picks up the hum of the pump through mechanical vibration.

The Perseverance rover is supposed to land on Mars on February 18, 2021 in the Jezero crater – it is believed that a riverbed used to pass through this area. This is one of those places where traces of living organisms on the planet could be preserved.

The main mission of the rover is to detect signs of life in order to advance the study of the ancient history of Mars. In addition, the device will become part of a mission to deliver samples from the surface of the red planet: it will dig out rock at certain points, and then another device will pick them up, which will send them to Earth.
