Earlier this morning, NASA's Solar Dynamics Observatory (SDO) witnessed a complex magnetic eruption on the sun. The joint NASA/ESA Solar and Heliospheric Observatory (SOHO) — a mission sitting at the L1 point between the Earth and the sun — also spotted a large coronal mass ejection (CME) blasting in the direction of Earth. It is thought that the SDO and SOHO observations are connected, making this a global magnetic disturbance affecting the whole of the Earth-facing side of the sun.

Ian O’Neill writes on Discovery News:
This isn’t an urgent call to arms, but it’s certainly a future date to consider. In the year 2182 — 172 years time — there’s the possibility that we might be hit by an asteroid with potential to cause some significant global turmoil.
This long-distance forecast could help mankind determine whether asteroid deflection techniques are warranted, especially when given nearly two centuries of lead time.
The not-so-romantically named (101955) 1999 RQ36 — discovered in 1999 — measures approximately 510 meters in diameter and is classified as an Apollo asteroid. Apollo asteroids pose a threat to our planet as they routinely cross Earth’s orbit.

With a one-in-a-thousand chance of 1999 RQ36 hitting Earth — with half of this probability indicating a 2182 impact — the threat might not sound too acute.
But compare this with the panic that ensued with the discovery of 99942 Apophis in 2004.
The reason I say “fun” post is it’s very unlikely a Nemesis star does exist, as we have been able to figure out masses and orbits in the solar system with a high degree of accuracy for quite some time. Meaning if an object this massive was this close — Nemesis is thought to be a red dwarf star or brown dwarf — we’d have to account for it in the astronomy.
In any event, I do expect Nibiru devotees to disagree with this opinion, or if/when WISE doesn’t find it.

Is our Sun part of a binary star system? An unseen companion star, nicknamed “Nemesis,” may be sending comets towards Earth.

Tess Pennington, 33, is a mother of three children, and lives in the sprawling outskirts of Houston, Texas. But she is not taking the happy safety of her suburban existence lightly.
Like a growing army of fellow Americans, Pennington is learning how to grow her own food, has stored emergency rations in her home and is taking courses on treating sickness with medicinal herbs.
“I feel safe and more secure. I have taken personal responsibility for the safety of myself and of my family,” Pennington said. “We have decided to be prepared. There all kinds of disasters that can happen, natural and man-made.”
Pennington is a “prepper”, a growing social movement that has been dubbed Survivalism Lite. Preppers believe that it is better to be safe than sorry and that preparing for disaster — be it a hurricane or the end of civilisation – makes sense.

Concerns over privacy have aligned with apocalyptic Biblical prophecy in a proposed Virginia law that limits the use of microchip implants on humans because of a lawmaker’s concern that the chips will prove to be the Antichrist’s “mark of the beast.”
On Wednesday, Virginia’s House of Delegates passed a bill that forbids companies from forcing their employees to be implanted with tracking devices, a move likely to be applauded by civil libertarians. But Virginia state Delegate Mark Cole’s reasons for proposing the law have as much to do with the Book of Revelation as they do with concerns over privacy in the digital age.
Cole says he is concerned that the implants will turn out to be the “mark of the beast” worn by Satan’s minions. “My understanding — I’m not a theologian — but there’s a prophecy in the Bible that says you’ll have to receive a mark, or you can neither buy nor sell things in end times,” Cole said, as quoted at the Washington Post.

A puzzling object that seemed to be a comet flying inside the solar system’s asteroid belt is no comet at all, but the remains of a violent collision between two fossil rocks that populate the belt, astronomers say.
Captured in images by the Hubble Space Telescope, the crash of the asteroids provides scientists with their first opportunity to see clear evidence of the violent activity that has constantly churned the asteroid belt since its formation, probably when the planets themselves were forming about 4.5 billion years ago.
The object was first sighted in early January by astronomers at the Air Force LINEAR project telescope in New Mexico, who reported it as a comet that must have flown into the asteroid belt from the solar system’s outer reaches, as all comets do. It was the fifth presumed comet to be reported in the unlikely region, they said, and they gave it the code name P/2010 A2.
Citing a more “hopeful state of world affairs” in relation to the twin threats posed by nuclear weapons and climate change, the Bulletin of the Atomic Scientists (BAS) is moving the minute hand of its famous Doomsday Clock one minute away from midnight. It is now 6 minutes to midnight. The decision by the BAS Science and Security Board was made in consultation with the Bulletin’s Board of Sponsors, which includes 19 Nobel Laureates
BAS announced the Clock change today at a news conference in New York City broadcast live at Turn Back The Clock for viewing around the globe. The new BAS Web platform allows people in all nations to monitor and get involved in efforts to move the Doomsday Clock farther away from midnight.
In a statement supporting the decision to move the minute hand of the Doomsday Clock, the BAS Board said: “It is 6 minutes to midnight.… Read the rest
Located in the binary system T Pyxidis, the white dwarf in question was originally thought to be far more distant from our solar system. Although three thousand light-years might sound like a fairly safe distance away from a potential supernova, it really is quite close by astronomical standards. To put it in some perspective, the diameter of the Milky Way, at roughly 100,000 light-years wide, is multiple orders of magnitude greater than what we're talking about here. The huge white dwarf in the T Pyxidis system is known as a recurrent nova because it undergoes relatively minor eruptions at regular intervals. Small nova explosions have been observed every twenty years for over a century, although the last recorded nova burst was in 1967. Astronomers are unsure why the star is overdue.

Space scientists in Russia are preparing to boldly go where no man has gone before, except for the actor Bruce Willis.
The head of the Russian space agency said today that it was considering a Hollywood-style mission to send a spacecraft to bump a large asteroid from a possible collision course with Earth.
Anatoly Perminov told the Russian radio station Golos Rossii: “People’s lives are at stake. We should pay several hundred million dollars and build a system that would allow us to prevent a collision, rather than sit and wait for it to happen and kill hundreds of thousands of people.”
The mission would be aimed at an asteroid called Apophis, he said, which is expected to pass close to the Earth in 2029 and again in 2036. “Calculations show that it’s possible to create a special-purpose spacecraft within the time we have, which would help avoid the collision.
