- 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

on January 23, 2019 at 3:58 pm
A new study tackles one of the greatest mysteries about Titan, one of Saturn's moons: the origin of its thick, nitrogen-rich atmosphere. The study posits that one key to Titan's mysterious atmosphere is the 'cooking' of organic material in the moon's interior. […]

on January 18, 2019 at 5:30 pm
Saturn's distinctive rings were observed in unprecedented detail by NASA's Cassini spacecraft, and scientists have now used those observations to probe the interior of the giant planet and obtain the first precise determination of its rotation rate. The length of a day on Saturn, according to their calculations, is 10 hours 33 minutes and 38 seconds. […]
Saturn hasn't always had rings
on January 17, 2019 at 7:21 pm
In its last days, the Cassini spacecraft looped between Saturn and its rings so that Earth-based radio telescopes could track the gravitational tug of each. Scientists have now used these measurements to determine the mass of the rings and estimate its age, which is young: 10-100 million years. This supports the hypothesis that the rings are rubble from a comet or Kuiper Belt object captured late in Saturn's history. […]

An image from the international Cassini spacecraft provides evidence of rainfall on the north pole of Titan, the largest of Saturn's moons. The rainfall would be the first indication of the start of a summer season in the moon's northern hemisphere. […]

New NASA research confirms that Saturn is losing its iconic rings at the maximum rate estimated from Voyager 1 and 2 observations made decades ago. The rings are being pulled into Saturn by gravity as a dusty rain of ice particles under the influence of Saturn's magnetic field. […]

Meteorite source in asteroid belt not a single...
on February 17, 2019 at 6:50 pm
A new study published online in Meteoritics and Planetary Science finds that our most common meteorites, those known as L chondrites, come from at least two different debris fields in the asteroid belt. The belt contains many debris fields created from former dwarf planets, or dwarf planets in the making, that collided long ago. These fragments, called asteroids, continue to collide, producing the meteorites that fall to Earth today. […]

An international study led by researchers from the Institute of Space Sciences, from the Spanish National Research Council (CSIC) and the Institut d'Estudis Espacials de Catalunya has discovered that carbonaceous chondrites, a class of meteorites, incorporated hydrated minerals along with organic material from the protoplanetary disk before the formation of planets. The researchers, who have published their results in the journal Space Science Reviews, note that these meteorites played "an […]
Kepler's final image
on February 12, 2019 at 1:25 pm
On October 30th, 2018, after nine years of faithful service, the Kepler Space Telescope was officially retired. With nearly 4000 candidates and 2,662 confirmed exoplanets to its credit, no other telescope has managed to teach us more about the worlds that exist beyond our solar system. In the coming years, multiple next-generation telescopes will be deployed that will attempt to build on the foundation Kepler built. […]
