Science experiment is bigger than the Large Hadron Collider.

In 2020 3 spacecraft will use laser fire to accurately measure the distance between them accurately enough to determine whether or not gravitational waves are real. How accurate does the measurement have to be? They will measure a distance of 3 million miles to an accuracy of 40 femtometers... roughly the distance of 15 protons side by side. This experiment will take place with the 3 spacecraft in orbit of the sun, Earth simply isn't big enough to get significant results.

We must have some incredible minds at NASA to take on a project this complex. Over 3 million miles the spacecraft would have to account for so many variables it's mind boggling, gravitational lensing from the sun should bend the laser light, open space isn't a perfect vacuum so the the light should slow down by a very small margin, redshift between 3 million miles would be incredibly miniscule, but at that accuracy very significant.... off the top of my head.

More is explained here, thanks and credit go to www.popsci.com.... again.

One of Jupiter's bands disappeared.

In late 2009 Jupiter left the view of our telescopes as it made it's orbit around the sun. It recently came back into view and it seems it may have left something behind...


One of Jupiter's most prominent bands, a stream of gas in the atmosphere which circles the planet in a specific region, has disappeared while it was behind the sun.

Apparently it's done this before, twice since 1973, and scientists expect the band to return within weeks or months.

Amazing New Hubble Image.

Really a mind opening view of the universe. check it out. Credit... of course, goes to NASA.

Anti-Matter Triggers Largest Explosion Ever.

I mostly want to use this blog to create a hub for science and technology articles around the web that i find interesting. This is my first blog post, it's taking more thought than i expected to write something interesting... i think the article pretty much speaks for itself.

"Late in 2009 year we witnessed the largest explosion ever recorded: a super giant star two hundred times bigger than the sun utterly obliterated by runaway thermonuclear reactions triggered by gamma ray-driven antimatter production. The resulting blast was visible for months because it unleashed a cloud of radioactive material over fifty times the size of our own star, giving off a nuclear fission glow visible from galaxies away." - DailyGalaxy.com, Anti-Matter Triggers Largest Explosion Ever

The largest explosion that humanity has ever caused was a three stage Thermonuclear bomb detonated by the Russians in 1961. It was equal to 50 Megatonnes of TNT or 1,400 times the combined yield of both nuclear bombs dropped on Japan in WWII. In comparison an earthquake that registers 9.5 on the richter scale is about 60 times more powerful. When a star goes supernova it releases about as much energy as our sun does every second, or roughly a few octillion warheads, and when a star goes hypernova it's about 100 times more powerful than that.
