Nasa has launched a new Zooniverse citizen science project to get you hunting for extrasolar dusty disks, planetary precursors, among 500,000 unidentified objects in the sky.

Disk Detective features images captured by the space agency’s Wide-field Infrared Survey Explorer (Wise), which between 2010 and 2011 captured one of the most detailed views of the Universe in infrared in four different wavelengths. The team at the Goddard Space Flight Center wants to use this data to get the public to identify the early beginnings of planets.

Anyone still not convinced?

NASA has released a new visualization showing how global temperatures have risen since 1950. It’s pretty much what you’d expect given that the level of carbon dioxide in our atmosphere is currently higher than at any time in the last 800,000 years.

This visualization was put together by NASA’s Goddard Institute for Space Studies (GISS). The group, which analyzes global surface temperatures on an ongoing basis, just released a rather sobering report on temperatures around the globe in 2013.

NASA says 2013 is now tied with 2009 and 2006 for the seventh warmest year since 1880. So, discounting 1998, the ten warmest years in the 134-year record have all occurred since 2000, with 2010 and 2005 ranking as the warmest years on record.

Swirling, stormy clouds may be ever-present on cool celestial orbs called brown dwarfs. New observations from NASA’s Spitzer Space Telescope suggest that most brown dwarfs are roiling with one or more planet-size storms akin to Jupiter’s “Great Red Spot.”

“As the brown dwarfs spin on their axis, the alternation of what we think are cloud-free and cloudy regions produces a periodic brightness variation that we can observe,” said Stanimir Metchev of the University of Western Ontario, Canada. “These are signs of patchiness in the cloud cover.”

The vintage Super Guppy aircraft is quite a story in and of itself.

NASA’s Orion spacecraft is just about ready to turn up the heat. The spacecraft’s heat shield arrived at the agency’s Kennedy Space Center in Florida Wednesday night aboard the agency’s Super Guppy aircraft.

The heat shield, the largest of its kind ever built, is to be unloaded Thursday and is scheduled for installation on the Orion crew module in March, in preparation for Orion’s first flight test in September 2014.

The heat shield completion and delivery to Kennedy, where Orion is being prepared, is a major step toward Exploration Flight Test-1 next year,” said Dan Dumbacher, NASA’s deputy associate administrator for exploration systems development in Washington. “Sending Orion into space for the first time is going to give us crucial data to improve our design decisions and develop Orion to send humans on future missions to an asteroid and Mars.”

NASA is the crown jewel of governmental agencies and a central player in the betterment of mankind.

The importance of NASA in the advancement of physics, chemistry, biology, psychology, economics, geography, and oceanography cannot be overstated.

I urge President Obama to lobby Congress to provide the American people a method to allocate a portion of their tax dollars to the direct funding of NASA. A simple checkbox, similar to how individuals can fund the Presidential Election Campaign Fund, should be added to all IRS tax forms.

On July 19, 2013, in an event celebrated the world over, NASA’s Cassini spacecraft slipped into Saturn’s shadow and turned to image the planet, seven of its moons, its inner rings — and, in the background, our home planet, Earth. Image Credit: NASA/JPL-Caltech/SSI

NASA has released a natural-color image of Saturn from space, the first in which Saturn, its moons and rings, and Earth, Venus and Mars, all are visible.

The new panoramic mosaic of the majestic Saturn system taken by NASA’s Cassini spacecraft, which shows the view as it would be seen by human eyes, was unveiled at the Newseum in Washington on Tuesday.

Cassini’s imaging team processed 141 wide-angle images to create the panorama. The image sweeps 404,880 miles (651,591 kilometers) across Saturn and its inner ring system, including all of Saturn’s rings out to the E ring, which is Saturn’s second outermost ring. For perspective, the distance between Earth and our moon would fit comfortably inside the span of the E ring.

“In this one magnificent view, Cassini has delivered to us a universe of marvels,” said Carolyn Porco, Cassini’s imaging team lead at the Space Science Institute in Boulder, Colo. “And it did so on a day people all over the world, in unison, smiled in celebration at the sheer joy of being alive on a pale blue dot.”

Here’s an excellent reason why we shouldn’t de-fund NASA. This is an important discovery, sure its not the holy grail of astronomy, extraterrestrial life. However, this is still an important discovery. I’m glad NASA was able to come back after the government shutdown ended, otherwise we wouldn’t be making as many discoveries about our Universe, and at this point who knows, we may still find microbial life on Titan, although it would have to be radically different than life on Earth, since all water there would be frozen solid, and it would be too cold for us to survive. That said its the only body in the solar system besides Earth that has a liquid on its surface.

Cassini Find: “Salt Flats” Surround Titan’s Northern Lakes - Read More about this over At IO9

We now have a better picture than ever of what the incredible landscapes of Saturn’s moon Titan look like. On the wet north pole of the moon, there are many enormous lakes — and newly-analyzed images from Cassini spacecraft reveal that they’re surrounded by dramatic salt flats.

For the first time, NASA has publicly confirmed what many people have suspected and speculated: On August 25, 2012, the Voyager 1 probe exited the Sun’s little bubble in space and began an exciting new journey into the interstellar medium. CNN has more here.

CNN) — At the edge of the heliosphere, you wouldn’t know by looking whether you left the cradle of humanity behind and floated out into interstellar space. You would just see unfathomably empty space, no matter which side of the invisible line you were on.
But scientists now have strong evidence that NASA’s Voyager 1 probe has crossed this important border, making history as the first human-made object to leave the heliosphere, the magnetic boundary separating the solar system’s sun, planets and solar wind from the rest of the galaxy.
“In leaving the heliosphere and setting sail on the cosmic seas between the stars, Voyager has joined other historic journeys of exploration: The first circumnavigation of the Earth, the first steps on the Moon,” said Ed Stone, chief scientist on the Voyager mission. “That’s the kind of event this is, as we leave behind our solar bubble.”
A new study in the journal Science suggests that the probe entered the interstellar medium around August 25, 2012. You may have heard other reports that Voyager 1 has made the historic crossing before, but Thursday was the first time NASA announced it.

If I say “meet me 28 miles from here,” that doesn’t seem very far, right? You could take a taxi, a bus; if pushed you might even make it on a bike.

But what if the 28 miles is not on a road or a highway, but straight up, 150,000 feet — that’s high. So high, we’re out of the life zone. Up in the silence.

This video, created by NASA and sound designed by the amazing folks at Skywalker Sound, lets you rise those 150,000 feet on a solid rocket booster, and then, after helping the space shuttle shoot into orbit, you (and the booster) tumble straight back to Earth.

It’s about two minutes up, then four minutes down, starting in lazy loops through the empty (except for the metal groaning) upper atmosphere; then the Earth’s surface swings with the arc of our fall, the atmosphere thickens, you hear wind, see inky, smoky moments, bursts of flame, winds start whistling by, groaning gets louder, clouds appear below like distant pillows, which we swoosh through and, after ejecting something, there’s a snap, parachutes suddenly appear and we drop, then splash into, under and out of the sea, only to watch something else toppling out of the sky nearby.
