perhaps we should also have "Religious News" somewhere... Ahmadinejad's prediction about Chavez would qualify...

You're making my job harder. So I'll change "geology" to "Earth Sciences". Ok?

Hidden stellar companions revealed almost next door.

This peaked my interest:

Quote:Luhman said the newfound star pair is not “Nemesis,” a hypo­thetical distant, dim object circling the Sun whose existence astronomers have long speculated about. This star system “is moving across the sky much too fast to be in orbit around the Sun,” he explained; this rapid motion is also one clue to its proximity.

Looks like they are still actively searching for it out there. Unfortunately the sky is huge and locating an individual brown dwarf is very, very difficult. They just happened to luck up on this find.

COMET DODGES CMEs: NASA's STEREO-B spacecraft has been monitoring Comet Pan-STARRS, taking hundreds of pictures as the comet passed by the sun this month. Yesterday, analyst Karl Battams of the Naval Research Lab assembled the data into a single movie spanning eight days, from March 9th through 16th. Click to set the scene in motion:



STEREO-B is stationed over the farside of the sun, so cameras onboard the spacecraft can look back and see Earth as well as the comet. In Battams' movie, the sun is located just outside the field of view on the left. Massive clouds of magnetized plasma (CMEs) billow away from the sun toward the comet, but according to Battams, none hit their mark:

"There were two CMEs in that sequence and it seems they went either side of the comet," he says. "That's a shame for us scientists because we would like to study how CMEs interact with a comet."

CMEs have been known to rip the tails off comets that pass too close to the sun, but that did not happen to Comet Pan-STARRS.

"By the way," adds Battams, "I've looked closely at the STEREO images and can see no indication of the possible fragment recently reported on spaceweather.com. I also haven't noticed any unusual brightening or disruption in the comet tail that would hint at such a fragmentation event having occurred."

Incidentally, here is the sun seven days ago. And of the sunspots are very weak in a part of the cycle where activity should be at its peak.

And look at it today, as it keeps revolving. Nothing is showing ahead. Really eerie isn't it?

I just love all these neat comet pictures.

One more parting shot as PanSTARRS heads back out to the outer solar system.

This is so nice: Hubble Telescope Snaps Stunning Nebula Photo for 23rd Birthday. I highly recommend you watch the video, but in full screen mode. Its in HDTV quality.

One of these years they will discover something erotic in the universe. I am sure the astronomers get off on the images they have found so far, so I mean something erotic to the rest of us.

It always amazes me how smugly sure the astronomers are of their observations and explanations. It is a good thing their days of theological power have long passed.
Jefferson: I place economy among the first and important virtues, and public debt as the greatest of dangers. To preserve our independence, we must not let our rulers load us with perpetual debt. We must make our choice between economy and liberty, or profusion and servitude. If we can prevent the government from wasting the labors of the people under the pretense of caring for them, they will be happy.

Here is something quite enlightening: Russia meteor virtually impossible to see coming. If you consider that the object was only about 15 metres in diameter, yet packed the equivalent of about 30 times the energy output of the Hiroshima atomic bomb, it should sober anyone.

And we are worried about Global Warming?

And we should be... this meteor was a loner, and now gone. GW has loads of co-conspirators everywhere, many in world governments.

Could be. Sure took him long enough to get around studying the fragments.

And yet another asteroid whizzes by earth, and inside lunar orbit: Asteroid the size of a small truck buzzes Earth: NASA. Its just a little smaller than the one that exploded in the Russian atmosphere earlier this year.

Let's play 'Duck and Cover'.

Man, I'd love to have one of those old desks.

I recall them. Long gone. Progress, you know.

Near misses by bolides is a definite threat, but an EMP Solar flare is 50-years overdue, and could wreak as bad or worse damage. A few politicians have worked to put something in place to minimize the damage expected, but there is little attention paid to it. Had Gingrich been elected, we would have a program ready - he is one of the few politicians with the scientific acumen to get it. Newt Gingrich calls EMPs “an enormous catastrophic threat.” Representative Ed Markey, a Democrat from Massachusetts, said, “the electric grid’s vulnerability to cyber and to other attacks is one of the single greatest threats to our national security.”

Another Carrington Event is due. Our most important components need to be protected by Faraday cages. Perhaps the scenario in the TV show Revolution may actually occur.

Quote:Hubble Space Telescope spots another moon orbiting Neptune

Get ready for a new naming contest! Astronomers with SETI — the Search for Extra-Terrestrial Intelligence — just confirmed that they've found a 14th moon orbiting the planet Neptune.

Say hello to S/2004 N 1, which SETI astronomer Mark Showalter found on July 1st. This tiny satellite, which is only around 20 kilometres wide, was found orbiting between the moons Larissa and Proteus, and it goes around Neptune every 23 hours.
When Showalter spotted this tiny dot, which the Hubble website says "is roughly one hundred million times fainter than the faintest star that can be seen with the naked eye," he wasn't even looking for it. He was using the powerful space telescope to track the planet's faint ring arcs.

They should name it Hubble or after the Astronomer who discovered it.
