Geomagnetic storm fears: Solar wind streaming from hole in the Sun hits Earth.


SOLAR winds blasting from a hole in the Sun’s atmosphere could cause a geomagnetic storm which has the power to wreak havoc on power and communications grids across the globe, it has been claimed.
The high-speed wind is grazing Earth’s magnetic field today after escaping from a gap in the star’s northern atmosphere.

Solar wind, which is actually a stream of charged particles and heat, typically takes between three and four days to reach Earth after being ejected from the Sun.

Geomagnetic storms are caused by solar winds affecting the Earth’s magnetic field
The high-speed wind is grazing Earth’s magnetic field today after escaping from a gap in the star’s northern atmosphere.

Solar wind, which is actually a stream of charged particles and heat, typically takes between three and four days to reach Earth after being ejected from the Sun.

 
And according to SpaceWeather.com, the latest high-speed particle stream has the potential to cause “geomagnetic unrest” as well as auroras around the Arctic Circle.

The latest activity comes just a day after NASA announced it had discovered a new sunspo and marks the first activity on the star’s surface for more than six months.
The sunspot, dubbed AR2699, caused a series of solar flares – changes in the sun’s brightness – which were observed from Earth.

Geomagnetic storms are feared for their ability to cause massive damage to satellites, power grids and communications networks.

A severe storm has the potential to wreak unprecedented havoc by knocking out phone, radio and internet systems for weeks, months or potentially even years.

The largest geomagnetic storm recorded to hit earth occurred in 1859 and disrupted telegraph systems across Europe and North America.
Also known as the Carrington Event, the storm produced auroras which were visible in many parts of the world as the charged particles from the sun smashed into Earth’s atmosphere.

Experts in the United States have warned if a geomagnetic storm on the same scale hit the planet again, it could cause damage costing trillions of dollars to repair.

A storm of similar power occurred in July 2012, though the area of the sun which produced the coronal mass ejection was not pointed directly at the Earth at the time.

In 2015, the Government published a report into the risks to the UK of severe space weather such as a solar storm.

Two Space Rocks Will Fly Safely Past Earth This Week.


Two space rocks will make close flybys past Earth this week, but they pose no threat to our planet’s safety.
The two asteroids are called 2018 CB and 2018 CC, and they were both discovered Sunday (Feb. 4) through an automated telescope search called the Catalina Sky Survey, according to NASA’s Minor Planet Center. The Catalina telescopes belong to just one of many observatories worldwide that regularly scan the sky to track and search for space rocks, also known as asteroids.

While the majority of asteroids in Earth’s solar system orbit in the asteroid belt between Mars and Jupiter, asteroid flybys of Earth happen several times a year. The last known close asteroid flyby was on Sunday (Feb. 4). The flybys are useful to astronomers because the researchers can examine the asteroids relatively close-up, gaining more information about the space rocks’ size, shape and composition.
You can watch livestreams of this week’s flybys courtesy of the Virtual Telescope Project, which uses remote-controlled telescopes to track near-Earth objects. (More details on the broadcast times are below.)

Both 2018 CB and 2018 CC are roughly the same size as a 17-meter (56-foot) space rock that exploded over Cheylabinsk, Russia, in 2013, causing property damage and thousands of injuries. 2018 CB is about 12 to 38 meters in diameter (39 to 124 feet), while 2018 CC’s diameter is estimated to be 9 to 28 meters (30 to 91 feet), according to the Minor Planet Center.

Unlike Chelyabinsk, however, both asteroids will fly past Earth instead of hitting it.

2018 CC will fly by today (Feb. 6), at 12:58 p.m. EST (1958 GMT), with a closest approach of about half the distance between Earth and the moon. The Virtual Telescope Project will start livestreaming views from a telescope in Arizona at 5 a.m. EST (1000 GMT), and from a telescope in Italy at 3 p.m. EST (2000 GMT).

2018 CB will zoom past Earth on Feb. 10 (Saturday) at 5:06 a.m. EST (1006 GMT), at 20 percent of the distance from the Earth to the moon. The Virtual Telescope Project will livestream this event from Italy only, starting Feb. 9 (Friday) at 3 p.m. EST (2000 GMT).

NASA and its Planetary Defense Coordination Office are among several agencies that regularly examine the sky to look for near-Earth objects such as 2018 CB and 2018 CC. Telescopes around the world and in orbit provide information about asteroids to NASA; details about those small bodies are typically uploaded to the agency’s Small-Body Database Browserwebsite that is available worldwide for scientists and the public to see.

There are currently no known asteroids that pose an imminent threat to life on Earth, but NASA and its partners are figuring out strategies to divert or destroy a potentially threatening object. Future mission concepts include ideas such as nets, lasers, gravitational diversion — or simply blowing up the asteroid.

NASA has a dedicated near-Earth object hunter in orbit called NEOWISE, which is expected to end its mission this year when the spacecraft’s orbit brings the machine into an area with too much sunlight to look for asteroids. A newer proposal by the same team, called NEOCam, failed to make the cut for NASA’s Discovery program in January.NEOCam did, however, receive more funding for another year.

Several asteroid missions are also in progress for the coming years. Japan’s Hayabusa2and NASA’s OSIRIS-RExare both in-flight to their target asteroids, where they will each collect samples to return to Earth. This year, NASA selected two new Discovery-class missions called Lucy and Psyche; between them, they will fly past eight asteroids in the 2020s and 2030s.

In 2005, Congress tasked NASA with identifying at least 90 percent of “potentially hazardous near-Earth asteroids” or those that are at least 140 meters (460 feet) wide and will come to within about 4.65 million miles (7.48 million kilometers) of Earth, or about 20 times the distance from Earth to the moon, according to the agency. NASA was given a deadline of 2020, but just four years later, a National Academy of Sciences reportsaid NASA likely wouldn’t meet the goal unless more funding arrived, and multiple reports since have stated that the agency is behind in meeting the goal. In 2010, the agency met another goal previously set by Congress of finding 90 percent of NEOs 1 km (0.6 mile) wide in 2010, according to NASA.

Venus was as habitable as earth for TWO BILLION years.


VENUS was once likely “abundant” in life, according to a startling report from Nasa
The planet second closest to the sun was probably once a perfect habitat for life with oceans of water and suitable temperatures, it has been revealed.

The barren planet we see today is highly volcanic and too hot to support any life, but this probably wasn’t always the case.

Temperatures now exceed 460 degrees celsius and has an atmosphere that too heavy and full of carbon dioxide.

However, computer algorithms ran by Nasa shows that for the first two billion years of its life when the sun was 30 per cent dimmer and much cooler and there would have been a shallow liquid ocean – factors that are essential for life as we know it.
Venus spins much more slowly on its axis than Earth, with a typical day on Venus lasting 117 Earth days.

This has allowed the atmosphere to become 90 times as thick as Earth’s.

Additionally, the more intense sunlight caused its oceans to evaporate which exacerbated the extreme carbon dioxide build up, according to the study published in Geophysical Research Letters.
Michael Way, a researcher at Nasa’s Goddard Institute for Space Studies (GISS), said: “Many of the same tools we use to model climate change on Earth can be adapted to study climates on other planets, both past and present.

“These results show ancient Venus may have been a very different place than it is today.”
Colleague Anthony Del Genio added: “In the GISS model’s simulation, Venus’ slow spin exposes its dayside to the sun for almost two months at a time.

“This warms the surface and produces rain that creates a thick layer of clouds, which acts like an umbrella to shield the surface from much of the solar heating.
“The result is mean climate temperatures that are actually a few degrees cooler than Earth’s today.”

Additionally, Nasa said that Venus likely had more landmass than Earth.

A statement read: “This type of surface appears ideal for making a planet habitable. There seems to have been enough water to support abundant life, with sufficient land to reduce the planet’s sensitivity to changes from incoming sunlight”.

Venus is NOT dead: Experts startled to see geological activity on planet.


VENUS, the planet which was thought to be ‘dead’, is actually showing signs of geological activity, astronomers have claimed.
Earth’s nearest neighbour and the planet which was once thought to be extremely similar to our own is showing signs of a changing landscape, long after it had been written off as dead, according to new research.

And experts say they have spotted signs of mountain ridge movement on Venus which is an extremely similar process to what happens on Earth.
Researchers analysed radar images taken by the Magellan mission which scanned Venus’ surface between 1990 and 1994.

The images revealed mountain ridges and valleys converged to produce flat plains of cooled lava.
The experts say they look like structures which are found on Earth and are similar to a process which took place in the Tarim Basin in northwestern China.

Paul Byrne, who presented his findings at the 2017 American Geophysical Union Fall Meeting in New Orleans and was leader of the study, said: “When you zoom out, you see that these features form a connected pattern.

“That’s when you realise that they seem to be working together.

“It’s not plate tectonics, but it does suggest that the outer, rigid, brittle surface layer of Venus, in some places at least, has broken into these small blocks,” some of which stretch up to 1,200 kilometres.
“These are little chunks of land that just rotate and move around.

“But if we were to put seismometers on Venus, maybe you’d hear some of these chunks go off today.”

Venus was once thought to be similar in condition to Earth and is in fact a similar size.
But over the course of its 4.6 billion year history, greenhouse gasses have taken its toll on the boiling hot planet – which is now even hotter than Mercury, the closest planet to the Sun.

Temperatures on the planet exceed 460 degrees celsius as it is high in volcanic activity and has a thick, heavy atmosphere that is full of carbon dioxide.

Venus spins much more slowly on its axis than Earth, with a typical day on Venus lasting 117 Earth days.

Mars was ‘destroyed by interplanetary NUCLEAR WAR’ in battle described in BIBLE.


THE ‘War in Heaven’ as described by the Bible was actually a nuclear war on Mars which rid the Red Planet of any life existing there, according to a group of Christians.
Huge devastation in Heaven was included in the Old Testament but now many believe there could be greater meaning.

Revelation 12:7 reads: “And there was war in heaven: Michael and his angels fought against the dragon; and the dragon and his angels fought.”

This leads on to Revelation 12:8-9, which says: “But he was not strong enough, and they lost their place in heaven.”

Christians and conspiracy theorists now believe that this was a “literal war” in the skies which took place on Mars and wiped out a civilisation on the Red Planet.
Dr John Brandenburg, a plasma physicist working as a consultant at Morningstar Applied Physics LLC, says in his book,’Death on Mars’, that nuclear isotopes found on the Red Planet “resemble those from hydrogen bombs on Earth” and a “Martian civilisation apparently perished due to a planet-wide catastrophe of unknown origin”.

According to conspiracy website Planet X News, this supposed war happened 75,000 years ago and was an interplanetary battle that happened between Mars and Maldek – a theorised planet once existing between Mars and Jupiter.

The war was between humanoids, which lived on Mars and reptilian creatures which occupied Maldek, the website claims.
While Maldek was completely destroyed, Mars was left uninhabitable and forced the residents of the Red Planet to move to Earth.

Planet X News claims: “The war was nuclear. Mars was seemingly losing, and the destruction of Maldek may have been an option of last resort.

“The Reptilians were fighting to control Mars and to utilise some of its resources, including mineral resources.
“Extraterrestrials systematically seeded information about the war into human culture by ‘force feeding’ information into minds of religious prophets.

“The prophets would then describe these ‘visions’ in ancient text.”
According to Dr Brandenburg, Earth could suffer a similar fate if we do not learn from the supposed signs of Mars’ end.

He writes in his book: “The discovery of dead civilisation on Mars, whose end was apparently catastrophic and due to unknown causes, reinforces our understanding that the cosmos can be a dangerous place and requires a vigorous response from the human race, to reduce the probability that we will perish the same way.”

New Research Around Mysterious Light Patches In Space Suggests Alternate Universe Could Exist


Scientists believe a glow in space could be signs of another, alternate universe existing close to ours.

The mystery light, spotted by researchers studying images from the European Space Agency’s Planck telescope suggests that our universe could be bumping into a neighbouring one.

Modern theories about how the universe began suggest that our universe is just one among many that emerged from the Big Bang.

According to new research, the bright spots could be the remnants of light originating from hydrogen gas that was given off from the Big Bang.

These conclusions are based on research from Ranga-Ram Chary of the Planck’s US data centre in California. New Scientist first reported on his analysis, and stated that the “eerie glow” he had observed “could be due to matter from a neighbouring universe leaking into ours.”

In order to arrive at this exciting conclusion, Chary and team compared the light leftover from the early universe — seen in the map of the cosmic microwave background — with an image of the sky taken by the European Space Agency’s Planck telescope.

The difference between the two revealed a mysterious spot of light.
“I would say most versions of inflation in fact lead to eternal inflation, producing a number of pocket universes,” Alan Guth of the Massachusetts Institute of Technology, told the New Scientist.

However, experts caution against getting too excited as previous mysterious patches of light have been explained by space dust.

“I suspect that it would be worth looking into alternative possibilities,” theoretical astrophysicist David Spergel told the New Scientist.

“The dust properties are more complicated than we have been assuming, and I think that this is a more plausible explanation.”
