- Get Lost in Space! (9/14/2018) - Way back in August, in anticipation of the start of a new school year, I set out to update the pages on this site related to space. Those pages tend to be popular among the teachers and students who use Cosma, and I happen to enjoy updating them, too. It sounded like a short, fun … Continue reading Get Lost in Space!
- Octopuses from Space! (5/20/2018) - Did you hear the one about the octopuses from space? It sounds like the title of a cheesy sci-fi movie, doesn’t it? But it isn’t, this time, or at least, yet. Instead, it’s actually an oddball theory that’s been put forth in a recently published “scientific” article that’s getting quite a lot of buzz in … Continue reading Octopuses from Space!
- NASA’s Excellent Adventures (9/13/2017) - NOTE: This post was updated on the morning of September 15th, see new videos below. NASA is always up to something fascinating. There are so many milestones and discoveries, it’s hard to resist featuring them in every post. However, there are a few events that definitely deserve special attention right now. First, August 20th and … Continue reading NASA’s Excellent Adventures
- Cassini’s Finale (5/1/2017) - The Cassini space probe has got a serious date with Saturn coming up in the Fall on September 15th, but she’s got a very busy schedule between now and then making a series of dives through the space between Saturn and its rings. The first dive of took place last week (Wednesday, April 26th). Here’s … Continue reading Cassini’s Finale

Saturn : the planet sixth in order from the sun — Webster
Saturn is the sixth planet from the Sun and the second-largest in the Solar System, after Jupiter. It is a gas giant with an average radius about nine times that of Earth. Although it has only one-eighth the average density of Earth, with its larger volume Saturn is just over 95 times more massive. Saturn is named after the Roman god of agriculture; its astronomical symbol (♄) represents the god’s sickle. — Wikipedia

Surprising chemical complexity of Saturn's rings...
on October 4, 2018 at 6:39 pm
A new study based on data from the final orbits last year of NASA's Cassini spacecraft shows the rings of Saturn -- some of the most visually stupendous objects in the universe -- are far more chemically complicated than previously was understood. […]
Saturn's famous hexagon may tower above the clouds
on September 5, 2018 at 7:54 pm
The long-lived international Cassini mission has revealed a surprising feature emerging at Saturn's northern pole as it nears summertime: a warming, high-altitude vortex with a hexagonal shape, akin to the famous hexagon seen deeper down in Saturn's clouds. […]
New family photos of Mars and Saturn from Hubble
on July 26, 2018 at 8:10 pm
In summer 2018 the planets Mars and Saturn are, one after the other, in opposition to Earth. During this event the planets are relatively close to Earth, allowing astronomers to observe them in greater detail. Hubble took advantage of this preferred configuration and imaged both planets to continue its long-standing observation of the outer planets in the solar system. […]

on June 27, 2018 at 8:04 pm
Using mass spectrometry data from NASA's Cassini spacecraft, scientists found that large, carbon-rich organic molecules are ejected from cracks in the icy surface of Saturn's moon Enceladus. Scientists think chemical reactions between the moon's rocky core and warm water from its subsurface ocean are linked to these complex molecules. […]

Building a submarine gets tricky when the temperature drops to -300 Fahrenheit and the ocean is made of methane and ethane. Researchers are working to determine how a submarine might work on Titan, the largest of Saturn's many moons and the second largest in the solar system. The space agency plans to launch a real submarine into Titan seas in the next 20 years. […]

Giant planets around young star raise questions...
on October 15, 2018 at 1:43 pm
Researchers have identified a young star with four Jupiter and Saturn-sized planets in orbit around it, the first time that so many massive planets have been detected in such a young system. The system has also set a new record for the most extreme range of orbits yet observed: the outermost planet is more than a thousand times further from the star than the innermost one, which raises interesting questions about how such a system might have formed.

Astronomy student searches for giant rings with...
on October 15, 2018 at 1:29 pm
Meticulous analysis of hundreds of photographic plates from the star J1407 between 1890 and 2007 show no stellar eclipses. Robin Mentel, a Master's student at Leiden University, could not detect eclipses of the star J1407 by a planet hypothesized to have giant rings, called J1407b. However, an eclipse may have been missed since the measurement series contains gaps. Mentel's research has been accepted for publication in the journal Astronomy and Astrophysics. […]
Five in a row—the planets align in the night sky

For the second time this year, the five brightest planets can be seen at the same time. You can catch them by looking towards the western sky after sunset. The planets will form a line rising up from the horizon. […]
