Local Supernova 10,000 years ago
Answer 1: It is saving them up for one almighty & nasty outburst (me). Answer 2:
This supernova from the special date of 10,000 years ago needs some more investigation!

This article looks at how "clouds of interstellar matter" can interfere with the solar wind, and allow more cosmic rays to hit earth, therefore causing more mutations!

"When a powerful event like a CME disturbs the solar atmosphere, Earth can feel the effects, even if the CME is not directed our way." - article at NASA "Huge loops of very hot gas rising above the Sun`s surface vibrate with enormous energy at times of solar storms." - article from ESA at EurekAlert link me RobertBast, June 12, 2002 at 7:41:00 AM AEST Brown dwarfs - no worries 
Astronomers have observed a brown dwarf orbiting a low-mass star - at a distance of just three times that which separates Earth and the Sun. Hard to see, brown dwarfs were once thought to all be drifting aimlessly around space (and therefore a threat to our planet). Now it appears that they are normally in orbit around another a star.

According to the article they will soon have detectors that will tell us if this is where cosmic rays originate from.
link me RobertBast, June 4, 2002 at 12:34:00 PM AEST Black Hole = Electric Motor? 
The magnetic fields extend for up to 10 million light years, and the energy is created by some form of dynamo in the center of the black hole. Los Alamos researchers believe that a "sudden reconnection or fusing" of magnetic field lines creates cosmic rays. Powerful stuff going on.
link me RobertBast, June 1, 2002 at 5:40:00 PM AEST Important new detectors Gravity Waves. Albert Einstein predicted their discovery as part of his general theory of relativity. A $300 million project called LIGO gets switched on in July. It consists of a wave antenna in two halves, one in New York and one in Livingston, La. A gravity wave is kind of like a space-quake, and will detect if a supernova occurs in our region. Or something undiscovered and just as dangerous?
Geomagnetic Field. SWARM is four satellites in two different polar orbits between 400 and 550 km altitude, which will make a global high-precision survey of the geomagnetic field. This will help scientists study the scary aspect of a magnetic pole shift.

But that might've only been a baby flare compared to what the sun has in store for us...

They say it might take hundreds of millions of years before it goes supernova, but fail to give us any minimum...
link me RobertBast, May 26, 2002 at 7:31:00 AM AEST NEAR Resurrection: Bringing Back the Dead Spacecraft See this previous article mentioning the "conspiracy theory" about a Hall of Records, NEAR and Eros... A death-defying comeback might be in store for NASA's Near Earth Asteroid Rendezvous (NEAR) spacecraft. The probe is now muted, quietly resting in a no-shout zone on the surface of asteroid 433 Eros.Sounds to me like they want an update, from a piece of rock where nothing should be happening. link me RobertBast, May 24, 2002 at 9:33:00 AM AEST CME on its way A solar coronal mass ejection (CME) is heading toward Earth. Sky watchers should be alert for auroras after sunset on Thursday, May 23rd, and again on Friday, May 24th. Forecasters estimate a 25% chance of severe geomagnetic activity at middle latitudes when the CME arrives. link me RobertBast, May 18, 2002 at 4:17:00 PM AEST Giant star plays bass Click here to hear it (MP3) -->starbass (audio/mpeg, 254 KB) Stars make sounds. The discipline of asteroseismology measures the oscillations. The internet lets you hear them! The new observations demonstrate that xi Hya oscillates with several periods of around 3 hours. It is well worth downloading the tune it makes (look for the link at ESO). Okay, it's speeded up a million times, but it has a rocking rhythm! European Southern Observatory Cosmiverse link me RobertBast, May 17, 2002 at 2:52:00 PM AEST 'Strangelets from outer space attacking Earth' Once or twice a year a strange, heavy "nugget" from outer space, as small as a blood cell but weighing about a tonne, may zoom through the Earth at up to 1,500,000 kmh.How scary is that? The culprits are apparantly "strange quark nuggets"--exotic bits of matter hypothesized to drift through space, but never detected. First proposed by Witten in 1984. Other physicists have calculated that they would dash through Earth with dramatic effect: a 1-ton fleck would unleash the energy of a 50-kiloton nuclear bomb, spread along its entire threadlike path. The scientists looked at hundreds of thousands of unexplained seismic events and found a few that could possibly be caused by such a hypothetical happening. (Or by chance!) Geologist Eugene Herrin, of the Southern Methodist University in Texas says "There would probably be a tiny crater but it would be virtually impossible to find anything." Australian physicist Anthony Thomas says "I don't think our knowledge of the structure of matter is good enough to know whether they (strangelets) do or don't exist." Telegraph Ananova InScight The Age link me RobertBast, May 15, 2002 at 8:56:00 AM AEST Cosmic catastrophe "a certainty" According to Dr Arnon Dar, of the Technion Space Research Institute, Israel, a particular type of exploding star going off anywhere in our region of the Universe would devastate our planet.A collapsed supermassive star would create a black hole that would "send out a beam of destructive radiation and particles that would sterilise any planet in its path" He has calculated that it would happen to Earth once every 100 million years or so. Article at BBC or Cosmiverse or Unknown Country link me RobertBast, May 14, 2002 at 7:15:00 AM AEST Earth expels gas The Earth reacts so strongly to the solar wind that it helps create space storms that disrupt electricity grids and satellite and radio communications, surprised NASA scientists said on Thursday.It's chaos up there! - story at CNN and NASA link me RobertBast, May 12, 2002 at 7:42:00 PM AEST Life-supporting ecosystem for space 
Purdue [University] will help design a self-sustaining environment for future space colonies. Residents will grow their own crops and live inside fully enclosed habitats in which all wastes are constantly being recycled and purified. Plants will provide foods and oxygen for humans, microbes will be used to break down wastes, and other technologies will be needed to remove impurities from the air and water.Good news for anyone planning on evacuating Earth in an emergency link me RobertBast, May 10, 2002 at 12:24:00 PM AEST Protecting Cosmonauts from Cosmic Rays When on the Earth, atmosphere and magnetosphere reliably protect people from the solar cosmic rays ruinous for all living beings. Out in the interplanetary space cosmonauts are vulnerable, unless special protection measures are involved. To fully shield human beings from space radiation the spaceship body should be about three meters thick, but the engine able to launch such a huge spaceship has not been invented yet. Certainly, the cosmonauts are shielded both by the environmental suits and by the spaceship body, but the protection is not sufficient. So, what can be the solution to the problem?Solution...They place radiation detectors throughout the spacecraft, so that the cosmonauts can hang-out in the least affected areas. Kinda like using the shadow of a tree as shade - when the shadow moves, you move too. NASA are working on it too: "On a trip to Mars and back, without the appropriate shielding, about every cell in the body would be traversed by one of these heavier articles."Read more about why having a roof 3 metres thick would be sensible if a pole shift removed the Earth's protection for a while: link me RobertBast, May 7, 2002 at 2:38:00 PM AEST X-Ray Flashes & Gamma-Ray Bursts may be related Researchers have concluded tentatively that X-ray flashes are the low-energy relatives of gamma-ray bursts, created by similar mechanisms. This implies that there are different degrees of ray bursts from neutron stars, black holes, and quasars - and that there's a good chance we haven't observed a big one yet. link me RobertBast, May 1, 2002 at 2:30:00 PM AEST Hot new Hubble pics 
Four striking images have been posted online, taken by the Advanced Camera for Surveys (ACS), which was installed aboard the NASA/ESA Hubble Space Telescope in March during Servicing Mission 3B.
The one above is of the strange "Tadpole Galaxy". See the images, read the story... link me RobertBast, April 27, 2002 at 10:31:00 AM AEST Cosmic ray mystery solved? The highest-energy particles in the Universe, known as galactic cosmic rays, have always puzzled scientists. The particles' source must be within 200 million light years of Earth, because cosmic rays from beyond this distance would lose energy as they traveled through cosmic microwave radiation. It has been uncertain what kinds of objects within this distance could generate such energetic particles. Answer: "retired" quasars - galaxies containing supermassive black holes that now appear lifeless "Each contains a central black hole of at least 100 million solar masses that, if spinning, could form a colossal battery sending atomic particles, like sparks, shooting off towards Earth at near-light speed,"The if is important, but their argument is sound enough...BBC or Cosmiverse BUT WAIT! They come from supernovas..... link me |
