BaBar data recently analyzed might confirm that time is wibbly wobbly timey wimey stuff. If you are a B meson, time may not run the same in both directions for you. This is based on a report in Physical Review Letters called “Observation of Time-Reversal Violation in the B0 Meson System” which has this abstract:…

Huge Eruption on Sun

I have 3D Sun on my iPad, and every now and then it beeps at me and tells me that something important is happening. Earlier today it beeped at me to tell me that an ENORMOUS solar eruption happened. Notice that the update just prior to the Huge Eruption is an update daying “NOAA forecasters…

Most Distant Galaxy Found (So Far)

So far indeed. It is blobbish and small, but interesting. From NASA: PASADENA, Calif. – By combining the power of NASA’s Hubble and Spitzer space telescopes and one of nature’s own natural “zoom lenses” in space, astronomers have set a new record for finding the most distant galaxy seen in the universe. The farthest galaxy…

The Drake Equation is that famous equation where you count how many stars there are, figure out the chance of a star having planets, of planets having water, etc. etc. until finally you get some rough estimate of the chance of live evolving elsewhere in the universe. It’s a little more complicated (and also simpler)…

Sitting on top of enough explosive stuff to send a heavy weight into orbit at a high speed is dangerous, and that has cost lives in the space program. Re-entering the earth’s atmosphere, effectively imitating a meteor as it burns up owing to the translation of the aforereferenced kinetic energy into heat is also dangerous…

Did Curiosity Find an Artifact on Mars?

Quite possibly. Here’s a picture of it: There’s a pretty good chance that this is a manufactured object and not some natural thingie that formed on the surface of Mars by Mars-esque natural processes. But, if that’s true, then there’s a pretty good chance that the object, formed by an intelligent being, is just some…

Do ghosts really exist? Is there life on Mars? Despite what one might think, what with large class sizes and the homogenization of culture caused by TV and Fast Food, the fact remains that clumps of high school students organized into classes can vary widely from one another. Each year has its own characteristics, and…

Welcome Comet ISON

Late Winter, 1997, just before moving from Boston to Minnesota, was very snowy out east. And, that year I had stupidly agreed to shovel the snow for our apartment building in exchange for a pittance of some kind. One night I was shoveling the latest 7 inch storm off the walk, and the father of…

Remember Rover? Rover is still finding stuff, and this latest find is strange, enigmatic, interesting, and worthy of further investigation. So far there is only a press release from NASA, here: NASA Mars Rover Opportunity Reveals Geological Mystery PASADENA, Calif. — NASA’s long-lived rover Opportunity has returned an image of the Martian surface that is…

From NASA: …astronomers have, for the first time, spotted planets orbiting sun-like stars in a crowded cluster of stars. The findings offer the best evidence yet that planets can sprout up in dense stellar environments. Although the newfound planets are not habitable, their skies would be starrier than what we see from Earth. The starry-skied…
