The Dobsonian telescope named after it's inventor, John Dobson brought the heavens to a great number of people. It was fairly cheap to make, but gave you the ability to see things in the sky that most store bought telescopes would never let you see. The first time I got to see Saturn for myself was through a Dobsonian telescope and Jupitar looked huge and I could even make out more than the four moons you normally can see.The Dobsonian telescope named after it's inventor, John Dobson brought the... more

NASA spacecraft offers detailed views of Saturn's Great White Spot
The Great White Spot, which occurs about once every 30 Earth years, is a windy, towering cloud of ammonia and water spewing out super jolts of thunder and lightning. The storm is about 10,000 times stronger than those on Earth.

Saturn's Great White Spot, a recurring storm on that planet that has intrigued scientists since it was first observed in 1876, is a windy, towering cloud of ammonia and water spewing out super jolts of thunder and lightning. Now astronomers and NASA's Cassini spacecraft, which has been orbiting Saturn since 2004, have captured the most detailed views to date of the phenomenon.
The luminous storm, which may be the gaseous planet's main mechanism for dissipating heat, occurs about once every Saturnian year, the equivalent of about 30 Earth years. The storms, however, do not follow a precise schedule. The latest round, the most intense on record, was first noticed by ground-based professional and amateur astronomers as a bright speck on Saturn's northern hemisphere on Dec. 5, about nine years before schedule. The previous storm occurred in 1990.
Their observations coincided with Cassini's detection of a deluge of radio waves emitted by Saturn. These radio waves are a signature of lightning and can be used as a measure of its strength.
During the days that followed, that small blemish, moving westward about 65 mph, grew to a size nearly equal to the diameter of the Earth. Two months later, the behemoth had blanketed the entire planet, spanning more than 180,000 miles.
"It turned into a very spectacular storm, with so many [lightning flashes] we couldn't resolve individual ones," said Donald Gurnett, a physicist at the University of Iowa and a contributing author of one of two reports published Wednesday in the journal Nature.
This massive eruption of lightning is caused when heat and water vapor rise from deep within Saturn's atmosphere up to its troposphere, the region of the atmosphere where weather occurs. When that water vapor cools and condenses, it releases heat and, under the right conditions, produces lightning.
The lightning on Saturn originates deep inside the planet's atmosphere, where vapors are at higher pressure. That makes the lightning very intense.
The images and measurements gave scientists new insight into the shape of the current Great White Spot. As water vapor and ammonia were pushed to the troposphere by vertical currents, some of the materials were dragged by eastern winds, creating the storm's characteristic "head" and straggling "tail," both of which are visible from Earth.
First author Agustin Sanchez-Lavega, a planetary scientist at the University of the Basque Country in Bilbao, Spain, and his colleagues were able to estimate that the storm's head, where most of the lightning was concentrated, extended about 160 miles below the cloud tops. Because the sun doesn't shine there, this suggests that the planet's internal heat helps the storms to form, the scientists wrote.
Great White Spots are 10 times larger than normal storms on Saturn and are about 10,000 times stronger than those on Earth. They occur seasonally due to changes in how much sunlight reaches Saturn. Scientists still don't fully understand the interplay between solar energy and Saturn's internal stores in generating these storms.Los Angeles Times...

Today, April 3rd, Saturn will be "at opposition"--opposite the sun in the skies of Earth. Whenever this event occurs, Saturn's rings surge in brightness, due to the Seeliger effect, also known as the opposition effect. Saturn's rings are made of water ice, with some contamination from dust and other chemicals, ranging in size from dust to objects as high as the Rocky Mountains. Sunlight directly backscattered from those ice particles causes the ring system to shine with greater intensity for the few days around opposition.

Recent data from NASA's Cassini spacecraft show that the variation in radio waves controlled by the planet's rotation is different in the northern and southern hemispheres. Moreover, the northern and southern rotational variations also appear to change with the Saturnian seasons, and the hemispheres have actually swapped rates.

Saturn's moon Titan has many of the components for life without liquid water. But the orange hydrocarbon haze that shrouds Saturn's largest moon could be creating the molecules that make up DNA without the help of water – an ingredient widely thought to be necessary for the molecules' formation according to a new study.

An enormous storm has erupted in Saturn’s northern hemisphere.
Amateurs first sighted the storm earlier this month, but the Cassini spacecraft moved into a good position on Dec. 24 to photograph it from about 1.1 million miles away. Earth received the raw and unprocessed shots today.
The storm has a huge central funnel and a long tail that sweeps around Saturn’s northern hemisphere for tens of thousands of miles. A shot in blue light (left) reveals the extent of the tail, but infrared light (right) shows detail of the storm’s amorphous core. The photos were taken exactly a month after Cassini recovered from a solar-flare-induced error that temporarily silenced the spacecraft from Nov. 2 through Nov. 24.
Saturn’s weather is complex like Jupiter’s, but it’s often difficult to see such storms beneath Saturn’s hazy outer atmosphere, wrote Carolyn Porco, a planetary scientist and leader of Cassini’s imaging team.

NASA is holding a press conference on Thursday "to discuss an astrobiology finding." Are they going to announce that they've found evidence of extraterrestrial life?
Blogger Jason Kottke took a look at NASA's press release, which touts "an astrobiology finding that will impact the search for evidence of extraterrestrial life" (astrobiology, besides being a cool word, is "the study of the origin, evolution, distribution and future of life in the universe"), and decided to investigate further by looking at the participants' resumes. So who are the participants?
A geobiologist who's written about "geology and life on Mars";
An oceanographer who's done extensive work on arsenic-based photosynthesis;
A biologist examining Titan, the largest moon of Saturn, and its similarities to early Earth;
And an ecologist investigating the "chemistry of environments where life evolves."
Now, yes, obviously, throw in a grizzled marine and you've got the making of an awesome movie about discovering aliens. But that's not (the only reason) why Kottke thinks the announcement will be about life on another world. Here's what he says:
So, if I had to guess at what NASA is going to reveal on Thursday, I'd say that they've discovered arsenic on Titan and maybe even detected chemical evidence of bacteria utilizing it for photosynthesis (by following the elements). Or something like that. (thx, sippey)
Of course, the announcement could be something totally different! Or, it could be that NASA has been contacted by a warlike race of space aliens and a certain-to-fail mission carried out by a ragtag bunch of scientists is our only hope of survival.
The picture, by the way, is the sun reflecting off a lake on Titan, "the only place in our solar system beyond Earth known to have liquid on its surface." HOW COOL IS THAT?!
Space, guys! Space!

NASA has called a press conference on Thursday "to discuss an astrobiology finding," and there's a hefty amount of speculation happening that suggests it could be to announce the finding of alien life.
NASA's press release says it's "to discuss an astrobiology finding that will impact the search for evidence of extraterrestrial life."
Speculation is growing that NASA has discovered life on one of Saturn's moons.
The space agency did not release more details, but the list of news conference participants is telling, according to blogger Jason Kottke.
