NASA discovers Hidden Portals in space between the Earth and the Sun

NASA has turned science fiction into science fact by announcing the discovery of hidden ‘portals’ in Earth’s magnetic field.

Called X-points or electron diffusion regions, rather than being intergalactic folds in space leading to different galaxies and planets, these portals aid in the transfer of the magnetic field from the Sun to Earth.

Essentially, these portals aid in the transfer of tons of magnetically charged particles that flow from the Sun causing the northern and southern lights and geomagnetic storms.

A NASA funded research project has discovered the existence of unexplained portals between the Earth and the Sun

‘We call them X-points or electron diffusion regions,’ said University of Iowa plasma physicist Jack Scudder, who is studying them.

‘They’re places where the magnetic field of Earth connects to the magnetic field of the Sun, creating an uninterrupted path leading from our own planet to the sun’s atmosphere 93 million miles away.’

Surrounding the Earth at distances from 10,000 to 30,000 miles away, the portals have been observed by NASA’s THEMIS spacecraft and Europe’s Cluster probes.

In 2014, the U.S. space agency will launch a new mission called Magnetospheric Multiscale Mission (MMS) which will consist of four spacecraft which will circle the earth to locate and then study the ‘X-points’

Usually the Earth's magnetic field deflects particles from directly traveling to the Earth, but the portals provide a direct route to our atmosphere

Specifically where the Earth and the Sun’s magnetic fields connect and where the unexplained portals are formed.

While Scudder and his team at the University if Iowa are unclear as to what the portals are yet, they have observed charged particles flowing through them, causing electro-magnetic phenomemon in the Earth’s atmosphere.

‘Magnetic portals are invisible, unstable and elusive. They open and close without warning and there are no signposts to guide us in,’ said Scudder.

Some of the portals are miniscule and disappear almost instantly, while some are large and fairly stable.

The magnetic force of lines between the Earth and the Sun is outlined here and it when these lines cross that portals can form

‘Magnetic portals are invisible, unstable and elusive. They open and close without warning and there are no signposts to guide us in,’ said Scudder.

Looking forward to the launch of the MMS mission in 2014, Scudder and his team have calibrated the technology sufficiently to locate the portals.

‘We have found five simple combinations of magnetic field and energetic particle measurements that tell us when we’ve come across a X-point,’ said Scudder.

‘A single spacecraft, properly instrumented, can make these measurements.’

Four of the most promising alien worlds in the solar system

The Earth’s biosphere contains all the known ingredients necessary for life as we know it. In a broad sense, these are: liquid water, at least one source of energy and a list of biologically useful elements and molecules.

But the recent discovery of a nutrient in the clouds of Venus reminds us that some of these ingredients exist elsewhere in the solar system. So where are the other most promising locations for extraterrestrial life?

Mars

Mars is one of the most Earth-like worlds in the solar system. It has a 24.5-hour day, polar ice caps that expand and contract with the seasons, and a large number of surfaces that have been created by water throughout the planet’s history.

The discovery of a lake under the south polar ice cap and methane in the Martian atmosphere (which changes with the season and even the time of day) makes Mars a very interesting candidate for life. Methane is important because it can be produced by biological processes. But the real source of methane on Mars is not yet known.

It is possible that there is life here, given the evidence that the planet once had a much more favorable environment. Today Mars has a very thin, dry atmosphere, almost entirely composed of carbon dioxide. This provides poor protection against solar and cosmic radiation. If Mars has managed to preserve some of its water reserves beneath its surface, it is possible that life could still exist.

Europe

Europa was discovered by Galileo Galilei in 1610, along with three other larger moons of Jupiter. It is slightly smaller than the Moon and orbits the gas giant at a distance of about 670,000 km every 3.5 days. Europa is constantly contracting and stretching by the competing gravitational fields of Jupiter and other Galilean moons. This process is known as tidal bending.

The moon is believed to be a geologically active world, like the Earth, because strong tidal curves heat its rocky, metallic interior and partially melt.

Europa’s surface is a vast expanse of water ice. Many scientists think that under the frozen surface there is a layer of liquid water – a global ocean that cannot freeze due to heat and which can be more than 100 km deep.

Evidence for this ocean includes geysers erupting through cracks in the surface ice, a weak magnetic field, and chaotic surface relief that could have been deformed by ocean currents circling below. This ice sheet insulates the underground ocean from the extreme cold and vacuum of space, as well as from Jupiter’s fierce radiation belts.

At the bottom of this oceanic world, we can find hydrothermal vents and volcanoes. On Earth, such features often support very rich and diverse ecosystems.

Enceladus

Like Europa, Enceladus is an ice-covered moon with a subsurface ocean of liquid water. Enceladus revolves around Saturn and first came to the attention of scientists as a potentially habitable world after the unexpected discovery of huge geysers near the moon’s south pole.

These jets of water emerge from large cracks in the surface and, given the weak gravitational field of Enceladus, are sprayed into space. This is clear evidence of the existence of underground storage of liquid water.

Not only water was found in these geysers, but also many organic molecules and, most importantly, tiny grains of solid silicate particles, which can only be present if the ocean’s subsurface water is in physical contact with the rocky bottom at a temperature of at least 90 ? C. This is very compelling evidence for the existence of hydrothermal vents at the bottom, providing the chemical composition necessary for life and localized energy sources.

Titan

Titan is Saturn’s largest moon and the only moon in the solar system with a solid atmosphere. It contains a thick orange haze of complex organic molecules and a methane meteorological system instead of water with seasonal rains, dry spells, and surface sand dunes created by wind.

The atmosphere is composed primarily of nitrogen, an essential chemical used to build proteins in all known life forms. Radar observations revealed the presence of rivers and lakes of liquid methane and ethane and, possibly, the presence of cryovolcanoes – volcano-like formations that spew liquid water rather than lava. This suggests that Titan, like Europa and Enceladus, has a supply of liquid water below the surface.

At such a huge distance from the Sun, Titan’s surface temperature is -180 Celsius, which is too cold for liquid water. But the abundance of chemicals available on Titan has given rise to speculation about the possible existence of life forms – potentially with a fundamentally different chemical composition from terrestrial organisms.

“Decision not made”: Head of NASA admitted that the US may not be able to land at the moon’s pole

The head of NASA is unsure about the ability of the United States to land at the Moon’s South Pole. The director of the agency admitted this to the scientists, admitting that instead of the pole, the astronauts can fly to the places of the previous Apollo landings.

NASA Director Jim Bridenstine made an unexpected statement, talking about plans for the first landing of American astronauts on the moon in 50 years. As you know, during the Artemis 3 mission, in accordance with the plans of President Donald Trump, the United States plans to carry out a manned launch to the Moon in 2024 and, for the first time since 1972, land astronauts on it in the region of the Moon’s South Pole.

During this mission, a week-long landing of “the first woman and another man” is planned on the surface of the Earth’s satellite.

Until recently, the fact that the landing is planned precisely in the polar region was not questioned – this is the most unexplored region of the Moon, scientists assume there are water deposits, and it is there that the Russian automatic station “Luna-25” will be launched in 2021.

However, the day before, speaking at an online conference of the Lunar Exploration Analysis Group, the head of NASA admitted that the flight to the South Pole would not take place. Answering the question whether it is possible in the future for astronauts to fly to the sites of past Apollo missions, the official not only answered in the affirmative, but also made it clear that this option is being considered for 2024.

“For the first Artemis 3 mission, our goal is to reach the South Pole, and of course, this is the most interesting place right now, because there is water ice, we need to study it, understand how to get it and use it,” Bridenstine said. “But I can imagine that these places (of the Apollo landings) can be interesting too.

If we decide that the South Pole is out of reach for Artemis-3, then perhaps we will learn more by going to where we left our instruments in the past … There may be scientific discoveries, and, of course, the very inspiration from the return to the Apollo landing sites will be amazing. However, these decisions have not yet been made”.

In doing so, the official added, the United States needs to develop “codes of conduct” to protect these historic sites from subsequent expeditions.

The Moon’s South Pole was designated the target of the first American astronaut landing in many years in 2019 in a speech by US Vice President Mike Pence at the National Space Council. “To reach the moon in the next five years, we must choose our goals now. NASA already knows that the South Pole is of great scientific, economic and strategic value, and now is the time to decide to go there,” the official said.

Now Bridenstein’s statement says that NASA may abandon its previous plans. Landing near the poles of the Moon is technically more difficult than in the equatorial or mid-latitudes, and neither automatic nor manned missions have landed near the poles before.

And although Bridenstein’s statement about the possible refusal to fly to the Pole is still vague, it has already worried the scientists attending the conference: at subsequent sessions they began to seek clarifications from NASA representatives.

This is due to the fact that the scientific tasks that must be set before scientists depend on the selected region. Just recently, NASA asked specialists to participate in the development of scientific problems that American astronauts could solve during the first landing on the moon in several decades.

“At this point, we are instructed to do our job with a polar landing in mind,” said Renee Weber of the Marshall Space Center when asked about a possible relocation of the landing site. According to representatives of NASA, the department has just begun to select certain areas. “The scientific community will be involved in this process,” said Jake Bleacher, head of one of the NASA divisions.

And while NASA continues to hope for a long-term base camp on the moon, agency officials have made it clear that it is not yet known whether a second manned mission, Artemis 4, will follow in the footsteps of the first. “We really need to assess the ability of our landers and what areas they can go to,” Bleacher said, adding that “it’s not clear” about how long after the first mission the second will go.

In the spring, it became known that Boeing had lost the competition for the design of lander, and Blue Origin, SpaceX and Dynetics were among the winners. Three winners of the competition were announced in April, under the initial contract SpaceX will receive $ 135 million, Blue Origin – $ 579 million, Dynetics – $ 253 million.

An amateur astronomer from Brazil discovered a large near-Earth asteroid

Brazilian amateur astronomer Leonardo Amaral discovered a large asteroid 2020 QU6 with a diameter of about 700 meters. He approached the Earth on Thursday and flew 40 million kilometers from its surface, the Planetary Society writes.

“This event was another reminder of what we have discovered, not all large near-Earth asteroids, we must continue to support the ground-based astronomy and invest in space projects, like the telescope NEOSM from cosmic threats to the full protection of the Earth.” – said  a leading adviser on space Casey Dreyer Planetary Society Policy.

Asteroid 2020 QU6, which Leonardo Amaral discovered at the end of August this year, has become one of the largest near-Earth asteroids in recent years. At the same time, he was not potentially dangerous for humanity and life on Earth, since in the foreseeable future he would not approach it at a dangerous distance.

It makes a revolution around the Sun in about 3.2 years, moving away from it twice as far as the Earth’s orbit is located. 2020 QU6 crosses the orbit of Mars and reaches the inner boundary of the main asteroid belt. At the maximum point of approach to the Sun, the asteroid almost reaches the Earth’s orbit, approaching the star by 1.1 astronomical units (the average distance between the star and our planet).

In the past few decades, scientists around the world have been actively monitoring near-Earth asteroids and conducting a kind of space “census” among them, trying to understand how dangerous they are for humanity. Now astronomers know about 22 thousand asteroids, which periodically approach the Earth at a relatively short distance.

Almost two thousand of them are included in the PHA (Potentially hazardous asteroids) catalog – a list of small celestial bodies that are potentially dangerous to life on Earth. To get on this list, an asteroid must approach our planet at a distance of no more than 8 million km, and also be large enough so as not to collapse when passing through the atmosphere and cause a regional catastrophe.
