The Mystery of “Hot Jupiters”

Over the last decade, astronomers have discovered thousands of exoplanets, many of which have gone against our current understanding of planet formation. Most of these exoplanets orbit very close to their star, as these are the easiest to discover since they block out more light from their respective stars than planets orbiting farther out do. […] Continue reading Continue reading

Jupiter’s Less Popular Moons

Io, Europa, Ganymede and Castillo get a lot of love, but the 63 other members of Jupiter’s posse are often overlooked. This NASA webpage provides in-depth information about each of Jupiter’s 67 moons. 50 of them are official moons and have names to reflect that status. However, the other 17 are mere “Provisional Moons,” which […] Continue reading Continue reading

Juno, the Probe to Jupiter

The Juno spacecraft is on its way to Jupiter, getting closer and closer as the years go by. Having left in August of 2011, five years later, Juno is due to arrive in July of this year. It is going to be the first solar-powered spacecraft to reach as far as Jupiter. Its mission is to study the… Continue reading Continue reading

Planet Discovered with Four Parent Stars

Binary star systems, like the one featured in the Tatooine system of Star Wars are common in the universe with half of all systems being comprised that way. Ternary system, or systems with three stars, are more rare, and even more rare are quaternion systems. Planets within these four star systems are also rare, so much so […] Continue reading Continue reading

Ganymede’s Ocean Confirmed?

Recent observations of Ganymede by Hubble appear to suggest that it may truly have an ocean far beneath its crust. Aurorae on the planet, caused by Ganymede’s magnetic field (the only moon in the solar system to have one), and their behavior seem to be suggestive of this high possibility. Ganymede’s distance from Jupiter allows […] Continue reading Continue reading

Could our Solar System have once had Super Earths?

New research appears to suggest that the early solar system might have been home to several “Super Earths,” terrestrial planets which are between 1 to 10 times the mass of Earth. One of the lingering questions about the formation of the solar system involves exactly how is it that the terrestrial planets of our solar system are so […] Continue reading Continue reading

Colliding with Jupiter

The Shoemaker–Levy 9 collision with Jupiter was the first direct observation of an extraterrestrial collision of Solar System objects. Shoemaker–Levy 9 disintegrated in to 21 fragments during a close encounter with Jupiter in July 1992 and finally collided with Jupiter two years later in July 1994. The remarkable collision lasted a week and left large, … Continue reading Colliding with Jupiter Continue reading Continue reading

Do we have Jupiter to thank for Earth?

A new study by the Proceedings of the National Academy of Sciences revealed that Jupiter may just be more than the largest gas giant planet in our solar system. We little earthlings may be here thanks to Jupiter and its…

Potential Ocean Underneath Jupiter’s Surface

Scientists using the Hubble Space Telescope have found out that there is an ocean beneath the surface of Jupiter’s largest moon, Ganymede. According to NASA officials, this ocean that is buried under a thick crust of ice may hold more water than the collective amount of water on Earth. Scientists think the ocean is 10 […] Continue reading Continue reading
