POPSQuiet Explosion: Object Intermediate Between Normal Supernovae And Gamma-ray Bursts Found Stars that were at birth more massive than about 8 times the mass of our Sun end their relatively short life in a cosmic, cataclysmic firework lighting up the Universe. The outcome is the formation of the densest objects that exist, neutron stars and black holes. When exploding, some of the most massive stars emit a short cry of agony, in the form of a burst of very energetic light, X- or gamma-rays.

POPSNew Space Telescope to Explore the Unknown Perhaps most exciting is the possibility that GLAST will find something no one is expecting. This space telescope can peer a range of high-energy gamma rays that is virtually unexplored. "There's such a leap forward in capabilities with GLAST that we have a really good chance of discovering things not even on the list yet," Ritz said. The mission is scheduled for liftoff atop a Delta 2 rocket at 11:45 a.m. EDT on June 7.

POPSThe ABCs of nuclear science - Interesting link * Do you want to know about the modern concept of the nucleus? * How nuclear physicists view the nucleus? * How could anyone measure something that small? * Do you know how we find new elements? * What are accelerators used for? * What is radioactivity and is it dangerous? * What do nuclear physicists really do?

POPSMagic rays signal new laws of the Universe The MAGIC telescope in the Canary Islands has found that gamma radiation traveled slightly slower than lower-energy photons by four minutes over a distance of 300 million light years. Perhaps there is more to Einstein's law of a universal speed of light. Perhaps the speed of light is only a generalization and not entirely correct or complete after all. Obviously there has to be an explanation, but what could it possibly be? Now it is up to the great minds to explain just what happened. I have my own ideas, but what do you think?

POPSString Theory news What it all seems to boil down to is that there is a whole heck of a lot we still don't know and probably never will. But we keep trying because that's what Humans do!

POPSFried By Nature A massive shockwave, much like the aftershock of a nuclear explosion, will sweep across the globe. A wall of fire will roast every living thing on Earth -- well, except a few fish, that is. The Gamma Ray Burst will reset evolution. Even a blast occurring farther out in the Milky Way won't be good for our health. OK, so the burst is too far away to fry us. But still, it will mess up our atmosphere. The energetic gamma rays will grind up the molecules our atmosphere is made of into separate molecules of nitrogen and oxygen. These atoms in turn will mop up the ozone layer, leaving us exposed to the deadly UV radiation from the Sun.

POPSMajor biological discovery…inside the Chernobyl reactor??
Possibly this could also be used to create plants or mushrooms that could grow in space, serving as a food source for space travellers. Maybe these fungi could be modified and used somehow to clean up radiation contaminated environments. There’s quite a few of those, in fact the disposal of radioactive waste is still a huge and unsolved problem. Now the fungi couldn’t actually eat the radioactive isotopes, I’m not saying that, but if they can live in radioactive environments they might be used to somehow scour out or concentrate the radioactive isotopes in such a way as to facilitate their clean up. Imagine, there’s fallout from a nuclear accident and what do the guys in suits do? They show up, spray mushroom spores over everything, and a few weeks later the mushrooms are harvested and disposed of while the contaminated area is now radiation free. It would certainly be useful, the picture at the top shows the still abandoned town of Priyat, Ukraine. It was built to house the workers

POPSNo supernova star deaths Slowly we are learning how the universe lives and breathes. We have a long way to go, but we are beginning to see we are dealing with a massive, complex and interrelated system. Next, the discovery of multiple universes within a infinite space. Can we handle it?
