Our Solar System: Rare Species In Cosmic Zoo

astroengine writes “Pulling from 20 years of research since the first discoveries of planets beyond our solar system, scientists have concluded that Earth and its sibling worlds comprise what appears to be a relatively rare breed in a diverse cosmic zoo that includes a huge variety of planet sizes, orbits and parent stars. The most common systems contain one or more planets one to three times bigger than Earth, all orbiting much closer to their parent stars than Earth circles the sun, says astronomer Andrew Howard, with the University of Hawaii.”

NOvA neutrino detector captures cosmic rays in 3D, aims to unlock the mysteries of the universe

NOvA

All apologies accepted if you mistook that image above as cover art for Daft Punk’s new album — it’s not (although the duo should consider it.). That Tron-ish, equalizer-like graphic is actually a 3D representation of particle activity left behind by cosmic rays interacting within NOvA, the Department of Energy’s under construction neutrino detector. It’s the first such visual record made possible by the University of Minnesota-operated facility that, when completed, will extend for more than 200 feet underground in an area near the Canadian border and endure regular bombardment by a controlled stream of neutrinos. Beyond its obvious visual appeal, data like this should give physicists at the DOE’s Fermi National Accelerator Laboratory insight into the nature of neutrinos (some of which are said to have been issued from the Big Bang) and, by extension, the origins of our ever-expanding universe. For now, though, the project’s still in the baby steps phase — only 12 feet of the detector (the currently operational portion) has been successfully built out — so the reality-shattering, scientific epiphanies will have to wait. Until then, it’s all still life as we safely know it.

Alt-week 3.23.13: Universal snapshots, cosmic world records and print your ride

Alt-week peels back the covers on some of the more curious sci-tech stories from the last seven days.

Alt-week 3.23.13: universal snapshots, cosmic world records and print your ride

If you are a fan of absolutes, then you are in the right place. We have a first, a fastest and a biggest in this week’s round-up of all things sci-tech. We’ll try to add one more to that — a quickest. The quickest intro for this feature ever. Did we manage it? This is alt-week.

How Cosmic Ray Muons Could Reveal Hidden Nuclear Waste

Muons were once used to “X-ray” an Egyptian pyramid. Now physicists hope to use a similar method to peer inside old nuclear waste repositories

Muons are charged particles rather like electrons, having the same charge but over 200 times the mass. They are continuously created by cosmic rays hitting the upper atmosphere and shower the ground at the rate of about one per square centimetre per minute.

Has a Biochem Undergrad Solved a Cosmic Radiation Mystery?



scibri writes “A few weeks ago, reports of a mysterious spike in carbon-14 levels in Japanese tree rings corresponding to the year 775 intrigued astronomers. Such a spike could only have been caused by a massive supernova or solar flare, but there was no evidence of either of these at that time. Until Jonathon Allen, a biochem undergrad at UC Santa Cruz, Googled it. He found a reference in the Anglo-Saxon Chronicle to a ‘red crucifix’ appearing in the sky in 774, and speculates that it could have been a supernova hidden behind a cloud of dust, which could mask the remnants of the exploded star from astronomers today.”

CERN: Neutrinos Respect Cosmic Speed Limit



An anonymous reader writes with news of a presentation from CERN Research Director Sergio Bertolucci about follow-up experiments trying to repeat the faster-than-light neutrino results from last year. Quoting the press release:
“The four [experiments], Borexino, ICARUS, LVD and OPERA all measure a neutrino time of flight consistent with the speed of light. This is at odds with a measurement that the OPERA collaboration put up for scrutiny last September, indicating that the original OPERA measurement can be attributed to a faulty element of the experiment’s fibre optic timing system. ‘Although this result isn’t as exciting as some would have liked,’ said Bertolucci, ‘it is what we all expected deep down. The story captured the public imagination, and has given people the opportunity to see the scientific method in action – an unexpected result was put up for scrutiny, thoroughly investigated and resolved in part thanks to collaboration between normally competing experiments. That’s how science moves forward.’”

Spaceballs! Cosmic buckyball ‘factory’ discovered

Until now, the only evidence in space for the bizarre little hollow balls of carbon atoms known as “buckyballs” has been in interstellar gases. But with the help of NASA’s Spitzer Space Telescope, astronomers have discovered buckyballs accumulating and stacking atop one another to form solid particles.

Galaxy cluster research supports Einstein’s Theory of Relativity on a cosmic level

In one small win for Einstein, one giant win for mankind, scientists at the Niels Bohr Institute have proved his General Theory of Relativity on a cosmic scale through their research of large galaxy clusters. Accordingly, the clusters — which are the largest known gravity-bound objects — have such a strong pull that they should cause light to “redshift,” or proportionally increase in wavelength, shifting towards the red end of the visible spectrum. To test it, researchers measured beams from 8,000 clusters, revealing that they do indeed cause a change in light’s wavelength, supporting Einstein’s theory to a T. One good turn deserves another, right Albert? Armchair cosmologists can hop on over to the source link to learn more.
