C, E-flat and G walk into a bar and the bartender says: “Sorry we don’t serve minors”, so E-flat leaves, and C and G have an open fifth between them. After a few drinks, the fifth is diminished and G is out flat. F comes in and tries to augment the situation, but is not sharp enough.

D comes in and heads for the bathroom saying, “Excuse me. I’ll just be a second.” Then A comes in, but the bartender is not convinced that this relative of C is not a minor. Then the bartender notices B-flat hiding at the end of the bar and says, “Get out! You’re the seventh minor I’ve found in this bar tonight.”

E-Flat comes back the next night in a three-piece suit with nicely shined shoes. The bartender says, “you’re looking sharp tonight. Come on in, this could be a major development.” Sure enough, E-flat soon takes off his suit and everything else, and is au natural.

Eventually C sobers up and realizes in horror that he’s under a rest. C is brought to trial, found guilty of contributing to the diminution of a minor, and is sentenced to 10 years of D.S. without Coda at an upscale correctional facility.

The ISS Has Ditched Windows Entirely — For Linux

Image/photo

The United Space Alliance has decided to stop using all Windows computers aboard the ISS, in favour of Linux — to ensure it’s systems are “stable and reliable”. Ouch.

The decision will see “dozens of laptops” change from running Windows XP to Debian 6, reports Extreme Tech. There are already Linux systems aboard the ISS, but from this point on Microsoft is banned. Keith Chuvala of the United Space Alliance has explained that the move to Linux will provide “in-house control. So if we needed to patch, adjust or adapt, we could.”

A flotilla of 10 or more tiny undiscovered moons might lurk in Pluto's orbit, complicating a spacecraft's planned flyby of the distant dwarf planet in 2015, new simulations suggest.

This preliminary finding could make life even more difficult for the team planning NASA's New Horizons mission, which is slated to take the first-ever up-close look at the Pluto system in July 2015. After Pluto's fifth known moon, a small satellite known as P5, was discovered last year, officials said they may need to redraw the spacecraft's path to avoid such obstacles.

Well, it was too cloudy at the horizon to see the Pan-STARR comet, but I took a nice photo of the sunset, all the same.

I don't know what name my child has picked out for this new friends, but I'm calling her "Stella Blue" for those striking blue eyes.

This photo is a little burnt out in the highlights, but I like it, anyway.

Monster black holes discovered

Image/photo

The two biggest black holes ever discovered have been found to be 10 billion times the size of our Sun.

SCIENTISTS HAVE DISCOVERED THE two biggest black holes ever observed, each with a mass billions of times greater than the Sun's, according to a new study published.

The two giants are located in the heart of a pair of galaxies several hundred million light years from Earth, said the study in scientific journal Nature.

Each black hole is estimated to have a mass about 10 billion times greater than the Sun, dwarfing the previously largest-known black hole, which has a mass of 6.3 billion suns.

The University of California, Berkeley, team led by Nicholas McConnell and Chung-Pei Ma said one black hole is located in NGC 3842, the brightest of a cluster of galaxies about 320 million light years from Earth.

The second hole is of "comparable or greater mass" and is located in NGC 4889, the brightest galaxy in the Coma cluster, about 335 million light years away.

Image/photo

RESEARCHERS HAVE DISCOVERED and mapped two enormous energy flows streaming out at supersonic speeds from the centre of the Milky Way.

The outflows, which were detected with CSIRO's 64m Parkes radio telescope, in NSW, are made up of hot gas and plasma, cosmic rays and magnetic fields. They are pouring from the centre of our galaxy at speeds of up to 1000km/s.

The finding, published in the journal Nature, follows the discovery of the Fermi bubbles: two giant bubbles of gas and energy that were detected by an international team of astronomers in 2010 using NASA's Fermi gamma-ray telescope.

Ice on Titan's Lakes: "May Host an Exotic Form of Life" --NASA/JPL

Image/photo

A new paper by scientists on NASA's Cassini mission finds that blocks of hydrocarbon ice might decorate the surface of existing lakes and seas of liquid hydrocarbon on Saturn's moon Titan. The presence of ice floes might explain some of the mixed readings Cassini has seen in the reflectivity of the surfaces of lakes on Titan.
"One of the most intriguing questions about these lakes and seas is whether they might host an exotic form of life," said Jonathan Lunine, a paper co-author and Cassini interdisciplinary Titan scientist at Cornell University, Ithaca, N.Y. "And the formation of floating hydrocarbon ice will provide an opportunity for interesting chemistry along the boundary between liquid and solid, a boundary that may have been important in the origin of terrestrial life."

Titan is the only other body besides Earth in our solar system with stable bodies of liquid on its surface. But while our planet's cycle of precipitation and evaporation involves water, Titan's cycle involves hydrocarbons like ethane and methane. Ethane and methane are organic molecules, which scientists think can be building blocks for the more complex chemistry from which life arose. Cassini has seen a vast network of these hydrocarbon seas cover Titan's northern hemisphere, while a more sporadic set of lakes bejewels the southern hemisphere.

Scientists think the variations in reflectivity, or brightness, have to do with the smoothness or texture of the surface. If a lake is fully liquid, it looks dark, but if it is only partially liquid, it looks brighter.

Up to this point, Cassini scientists assumed that Titan lakes would not have floating ice, because solid methane is denser than liquid methane and would sink. But the new model considers the interaction between the lakes and the atmosphere, resulting in different mixtures of compositions, pockets of nitrogen gas, and changes in temperature. The result, scientists found, is that winter ice will float in Titan's methane-and-ethane-rich lakes and seas if the temperature is below the freezing point of methane—minus 297 degrees Fahrenheit (90.4 kelvins).

The scientists realized all the varieties of ice they considered would float if they were composed of at least 5 percent "air," which is an average composition for young sea ice on Earth. ("Air" on Titan has significantly more nitrogen than Earth air and almost no oxygen.)

If the temperature drops by just a few degrees, the ice will sink because of the relative proportions of nitrogen gas in the liquid versus the solid. Temperatures close to the freezing point of methane could lead to both floating and sinking ice - that is, a hydrocarbon ice crust above the liquid and blocks of hydrocarbon ice on the bottom of the lake bed. Scientists haven't entirely figured out what color the ice would be, though they suspect it would be colorless, as it is on Earth, perhaps tinted reddish-brown from Titan's atmosphere.

"We now know it's possible to get methane-and-ethane-rich ice freezing over on Titan in thin blocks that congeal together as it gets colder—similar to what we see with Arctic sea ice at the onset of winter," said Jason Hofgartner, first author on the paper and a Natural Sciences and Engineering Research Council of Canada scholar at Cornell. "We'll want to take these conditions into consideration if we ever decide to explore the Titan surface some day."

Cassini's radar instrument will be able to test this model by watching what happens to the reflectivity of the surface of these lakes and seas. A hydrocarbon lake warming in the early spring thaw, as the northern lakes of Titan have begun to do, may become more reflective as ice rises to the surface. This would provide a rougher surface quality that reflects more radio energy back to Cassini, making it look brighter. As the weather turns warmer and the ice melts, the lake surface will be pure liquid, and will appear to the Cassini radar to darken.

"Cassini's extended stay in the Saturn system gives us an unprecedented opportunity to watch the effects of seasonal change at Titan," said Linda Spilker, Cassini project scientist at NASA's Jet Propulsion Laboratory, Pasadena, Calif. "We'll have an opportunity to see if the theories are right."

Monster Quasar Discovered with Power Outflow 100 Times Milky Way Galaxy

Monster Quasar Discovered with Power Outflow 100 Times Milky Way Galaxy

Image/photo

Researchers have discovered a quasar known as SDSS J1106+1939 with the most energetic outflow ever, a finding that may answer questions about how the mass of a galaxy is linked to its central black hole mass and why there are so few large galaxies in the universe. The rate that energy is carried away by the huge mass of material ejected is equivalent to two trillion times the power output of the sun. The black hole at the heart of quasar SDSS J1106-1939 is massive, estimated to be a thousand times heavier than the black hole in the Milky Way.
"This is about 100 times higher than the total power output of the Milky Way galaxy — it's a real monster outflow," said Nahum Arav, an associate professor of physics in College of Science at Virginia Tech and leader of the research team, which includes Benoit Borguet, now a postdoctoral researcher now at the University of Liege, Belgium; Doug Edmonds and Carter Chamberlain, both graduate research assistants at Virginia Tech, and Chris Benn, a collaborator who works with the Isaac Newton Group of Telescopes in Spain.

Astronomers have spotted the largest known spiral galaxy - by accident.

Image/photo

The ultraviolet range that Galex can see in revealed a wealth of new stars at the galaxy's outer reaches

A team was looking through data from the Galaxy Evolution Explorer (Galex) satellite for star-forming regions around a galaxy called NGC 6872.

But they were shocked to see a vast swathe of ultraviolet light from young stars, indicating that the galaxy is actually big enough to accommodate five of our Milky Way galaxies within it.

The find was reported at the American Astronomical Society meeting in the US.

NGC 6872, a galaxy about 212 million light-years away in the constellation Pavo, was already known to be among the largest spiral galaxies.
