Could our Solar System have once had Super Earths?

Posted on April 5, 2015 by agiantchicken

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 →

WASP-12b

Posted on April 5, 2015 by alephnulluniverse

WASP-12b is an HUGE planet that orbits extremely closely to its star. Due to the close distance (at 1/44 the distance compared to the distance between Earth and the Sun), WASP-12b has a very low densities from the flux of energy from the star and is being distorted into an egg shape. The most interesting […] Continue reading →

Saturn 2.0

Posted on April 5, 2015 by jamej00

So all the planets know that Saturn’s rings give it a really over-inflated ego.  But now there’s good news!  Maybe it’ll quit bragging now that it looks like there’s another planet with a bigger ring system.  Scientists think they’ve found an extrasolar planet with an elaborate ring system, the first discovery of a planet with… Continue reading →

Ganymede’s Ocean

Posted on April 5, 2015 by pgolemanska

When we think of Earth we tend to associate it very strongly with water and life. It makes sense since water covers up 75% of Earth’s surface. Water in liquid form seems to be unique to our world … or does it? … As it turns out, Earth’s salty water oceans may not be the […] Continue reading →

The Cosmic Snowball

Posted on April 5, 2015 by jamej00

Halley’s Comet This video tells us about the history of Halley’s Comet, which turns out to have actually been documented in medieval history in previous passes by the sun.  Because of the rarity with which comets actually appear in our night sky, they used to be tied to ancient superstitions; for example, to the ancient Chinese they signaled a… Continue reading →

Gamma-ray Bursts

Posted on April 5, 2015 by matthewrbirnbaum

Let’s start this post with what gets everyone’s attention during class: mass extinction. This somber topic always seems to turn heads. If collisions and exploding suns aren’t enough to make you fear extinction billions of years away, a new paper introduces us to a new threat that potentially could have wiped out most of life […] Continue reading →
