Saturn and its Moons

Posted on April 3, 2017 by Haley's Comet

Saturn lays outside of the asteroid belt among the giant planets. With a total of 53 moons (or 62 pending a few new discoveries),  Saturn is a planet that yields a huge amount of force in the Solar System. The moons orbiting Saturn are all unique and have distinct features. Titan, Saturn’s largest moon, has an atmosphere… Continue reading Saturn and its Moons Continue reading →

Blog 5: Enceladus’ Ocean

Posted on April 3, 2017 by lillyastro2110

One of Saturn’s moons, we discussed in class interesting details of Enceladus. The most notable of these is the geysers of water and the potential subsurface ocean. Methane found among other particles in the water vapor plume have led researchers to consider a subsurface ocean as the origin of this methane. Because of the high … Continue reading Blog 5: Enceladus’ Ocean Continue reading →

The Trojans and Greeks

Posted on April 3, 2017 by pkunetz97

As was recently discussed in class, there are two clusters of asteroids ahead of and behind Jupiter known as the “Trojans” and the “Greeks”. The first one to be discovered was an asteroid now known as “Achilles”, a hero who fought on the Greek side of the Trojan War. The Greeks are all slightly ahead […] Continue reading →

Ida and Dactyl

Posted on April 2, 2017 by Nick Belsten

243 Ida is a 56 km long asteroid orbiting in the main asteroid belt with a number of notable features. Ida is an S-type asteroid, or stony asteroid, and is mostly composed of rock and iron from accretion during early solar system formation. Ida was a subject of study by the Galileo spacecraft in 1993, … Continue reading Ida and Dactyl → Continue reading →

Comet Shoemaker-Levy 9

Posted on April 2, 2017 by Nick Belsten

In 1994, one year after its discovery, the fragmented remains of Comet Shoemaker-Levy 9 crashed into Jupiter’s upper atmosphere in a sequence of 23 large impacts, each releasing the energy equivalent of 25,000 megatons of TNT, more than one million times as much energy as released by the nuclear bomb dropped on Hiroshima. Orbital analysis … Continue reading Comet Shoemaker-Levy 9 → Continue reading →

Ballooning on Venus

Posted on April 2, 2017 by Nick Belsten

After their launch in 1984, the identical spacecraft Vega 1 and Vega 2 launched from a Russian Proton Rocket for their double mission of flying through the tail of Halley’s Comet and landing scientific payloads on the surface of Venus. In addition to a regular parachuted lander, the Vega spacecraft each carried a 22-kilogram balloon … Continue reading Ballooning on Venus → Continue reading →

Pluto is a Planet Again!

Posted on April 2, 2017 by brandonandthesolarsystem

April fools! I know I am a day late with this, but I was surprised to find that this was a common thread appearing on my Facebook feed over the weekend. As is common when “news” appears on social media, an “article” was being passed around that seemingly few people even bothered to read. Instead, the headline […] Continue reading →

Nuclear Fusion Powering Earth

Posted on April 2, 2017 by astr2110tmcm

The core of the Sun is at such extreme temperature and pressure that in that core hydrogen atoms are constantly fusing into helium and giving off massive amounts of energy. The Sun fuses about 4.25 million metric tonnes of hydrogen every second, which provides a power generation of 3.8 x 10^26 watts. By contrast, the […] Continue reading →
