WAIT WHAT IF EVEN THOUGH SATURN IS A GAS GIANT ITS ISODENSITY SURFACES HAVE SOCCER-BALL POLYHEDRAL SYMMETRY

Jupiter from Voyager
A strange lonely planet found without a star
An international team of astronomers has discovered an exotic young planet that is not orbiting a star. This free-floating planet, dubbed PSO J318.5-22, is just 80 light-years away from Earth and has a mass only six times that of Jupiter. The planet formed a mere 12 million years ago, a newborn in planet lifetimes.
"We have never before seen an object free-floating in space that that looks like this. It has all the characteristics of young planets found around other stars, but it is drifting out there all alone," explained team leader Dr. Michael Liu of the Institute for Astronomy at the University of Hawaii at Manoa. “I had often wondered if such solitary objects exist, and now we know they do.”
The discovery paper of PSO J318.5-22 is being published by Astrophysical Journal Letters and is available at http://arxiv.org/abs/1310.0457.

Yesterday was a BIG day for Mars exploration — the first scoop of Mars soil analyzed by NASA’s Mars Science Lab in October is 2% water by weight. This is groundbreaking as this will be a valuable resource for future colonists and could have ramifications for the continuing search of microbial life on Mars. Find out more

OH MY GOSH REALLY THIS IS SO COOL AUGH HUMANITY
Plus, there’s this incredibly scary but really fucking cool clip of what interstellar space sounds like.
Maybe this is why it took women so long to go where no man has gone before.
In NASA’s defense, it’s come a long way.
Last month NASA announced its new team of eight trainee astronauts, including four women. That means 50 percent are women — the highest percentage ever picked by NASA for a class of astronaut candidates.
This isn’t the first time NASA has benefited from the work of amazing women innovators, astronomers, and scientists. The trainees are following in the footsteps of inspiring women like Nancy Grace Roman, the first woman to hold an executive position at NASA. Or Judith Resnik, who received an AAUW fellowship and went on to become the second American woman in space. Or Mae Jemison, a physician and science mission specialist for the Endeavour and the first African American woman in space.These women not only succeeded in establishing themselves in a male-dominated field where women were not always welcome, but they also paved the way for the astronomers of today and tomorrow.
2013 is going to be an amazing year.
Here’s the schedule for this comet.
August and September 2013. The comet should become visible in August and September 2013 to observers at dark locations using small telescopes or possibly even binoculars.
October 2013. Comet ISON should become visible to the unaided eye, but only barely in the early part of the month. The comet will be sweeping in front of the constellation Leo then. It’ll pass first near Leo’s brightest star Regulus, then near the planet Mars. Maybe these brighter objects will help you find it that month. Meanwhile, the comet itself will be getting brighter during October.
November 2013. Comet ISON will continue to brighten throughout the month as it nears its late November perihelion (closest point to our sun). Plus ISON will pass very close to the bright star Spica and the planet Saturn, both in the constellation Virgo. Its perihelion (closest point to our sun) on November 28 will be an exciting time. The comet will come within 800,000 miles (1.2 million km) of our sun’s surface. If all goes well, and the comet doesn’t break up (as comets sometimes do), the terrific heating Comet ISON will undergo when it’s closest to our parent star might turn the comet into a brilliant object. Some are predicting that ISON will become as bright as a full moon! That would make Comet ISON a daylight object, briefly. Remember, though, at perihelion, Comet ISON will appear close to the sun on the sky’s dome (only 4.4° north of the sun on November 28). Although the comet will be bright, you’ll need to look carefully to see it in the sun’s glare. Some expert help around this time might be called for, and we’ll announce comet-viewing parties as we hear about them.
December 2013. This may be the best month to see Comet ISON, assuming it has survived its close pass near the sun intact. The comet will be visible both in the evening sky after sunset and in the morning sky before sunrise. As ISON’s distance from the sun increases, it’ll grow dimmer. But, for a time, it should be as bright as our sky’s brightest planet, Venus, and it should have a long comet tail. People all over Earth will be able to see it, but it’ll be best seen from the Northern Hemisphere as 2013 draws to a close.
January 2014. Will ISON still be visible to the eye? Hopefully. And on January 8, 2014, the comet will lie only 2° from Polaris — the North Star.

Watch this please. It’s only a little over 5 minutes.
It’s about NASA, but…please. Watch it. If you can’t watch it, bookmark it or something and watch it later. Please.
This is about how NASA influenced the entirety of the US culture into innovation and forward thinking. I guarantee your view of the US space program will change drastically, for the better.

Found! 3 Super-Earth Planets That Could Support Alien Life
The habitable zone of a nearby star is filled to the brim with planets that could support alien life, scientists announced today (June 25).
An international team of scientists found a record-breaking three potentially habitable planets around the star Gliese 667C, a star 22 light-years from Earth that is orbited by at least six planets, and possibly as many as seven, researchers said. The three planet contenders for alien life are in the star’s “habitable zone” — the temperature region around the star where liquid water could exist. Gliese 667C is part of a three-star system, so the planets could see three suns in their daytime skies.
