The Interiors of the Giants of the Solar System
The giants of our solar system, other than the Sun of course, are quite different from the terrestrial planets whether it comes to the atmospheres, the surfaces, size, or other planetary features. One key difference is the interior of these giant planets. Terrestrial planets, for context, have a very dense core followed by a rockyContinue reading “The Interiors of the Giants of the Solar System” Continue reading
Saturn on Steroids
Way out in the constellation Centaurus is a peculiar solar system 434 light years away that fascinates astronomers. The central star, named 1SWASP, is similar to our Sun in size and doesn’t appear to have any unusual characteristics for a main-sequence star. However, it was discovered in 2007 that 1SWASP is orbited by one enormousContinue reading “Saturn on Steroids” Continue reading
The Real Villain in Pluto’s Demise
The removal of Pluto as a planet was an emotional blow to anyone with a heart. It was a devastating betrayal leaving many asking questions that no one wanted to hear the answers to. While there were many reasons behind Pluto’s status change, the ultimate culprit is the dwarf planet Eris. Eris was discovered inContinue reading “The Real Villain in Pluto’s Demise” Continue reading

Meet Makemake: The Dwarf Planet Partially Responsible for Pluto’s Demotion
Pluto was discovered in 1930, and was classified as a planet. In 2006, as most of us probably know, Pluto was reclassified as a dwarf planet. A significant amount of the population, whether justified or not, are opposed to the removal of Pluto from the official list of planets, primarily out of nostalgia for oneContinue reading “Meet Makemake: The Dwarf Planet Partially Responsible for Pluto’s Demotion” Continue reading

Wasp-76b
Two weeks ago, scientists observed an iron rain type phenomenon on an exoplanet known as Wasp-76b. Wasp-76b is a gas giant that is located approximately 640 light years away from the constellation Pisces. Wasp-76b orbits a different sun in its own galaxy. The distance between Wasp-76b and the sun it orbits is about 3% ofContinue reading “Wasp-76b” Continue reading
Could Pluto Become a Planet Again?
When I learned the order of the planets in elementary school, Pluto was still considered a planet. About 14 years ago, it was demoted to a dwarf planet. The International Astronomical Union has three criteria in determining planetary status. It is in an orbit around the sun, it has sufficient mass to assume hydrostatic equilibrium,Continue reading “Could Pluto Become a Planet Again?” Continue reading

The Importance of Extrasolar Planets
Extrasolar planets, often called exoplanets, are planets that exist in other solar systems other than our own. These planets are very hard to find and study because their light is fainter than the light given off by the stars which they orbit. In 1992, astronomers Aleksander Wolszczan and Dale Frail noticed several planets orbiting theContinue reading “The Importance of Extrasolar Planets” Continue reading

What do we know about exomoons?
Unfortunately, this question has an easy answer: not much. So far, no exoplanet has been confirmed to have a moon, even though scientists are detecting planets the size of the Jovians. Even though nothing has been confirmed, however, there have been some interesting potential discoveries. We say potential because again, the systems are so farContinue reading “What do we know about exomoons?” Continue reading
Jovian Planet Interiors
The Jovian planets are often called “gas giants,” making it sound as if they were entirely gaseous. However, this name can be misleading, as it is true Jupiter and Saturn became giant primarily because they captured so much hydrogen and helium gas, but their strong gravity compresses most of the “gas” into forms of matterContinue reading “Jovian Planet Interiors” Continue reading
Why Does Titan Have an Atmosphere?
It’s pretty perplexing as to why Saturn’s moon, Titan, has such a thick atmosphere but a planet like Mars does not. Since the most widely accepted explanation of why Mars has such a thin atmosphere is it losing its magnetosphere as its core cooled and does not contain nearly as much metallic iron has theContinue reading “Why Does Titan Have an Atmosphere?” Continue reading
