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 →

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 →

The Mystery of the Mass Extinction

Posted on April 5, 2015 by oliviasn

Before reading the section in Chapter 12 of the textbook on cosmic collisions (Section 12.4), I had not realized that there exists some controversy as to whether or not an impact killed the dinosaurs. I had always been taught that an asteroid hitting the Earth resulted in the mass extinction and had never considered that […] Continue reading →

Voyager 2

Posted on April 5, 2015 by michellelei

Almost all of the information and pictures scientists have today from the outer planets is due to flyby missions such as NASA’s Voyager 2. As we learned in the last unit, flyby space probes are especially helpful because they can pass by and gather information on multiple planets within one single mission, and that is… Continue reading Voyager 2 Continue reading →

White dwarf supernovae

Posted on April 4, 2015 by newbeelity

White dwarf supernovae only occur in a binary system, in which one of them is a white dwarf while the other can be a giant star or just a main sequence star. As far as we know, a white dwarf is the remnant of a star after the nuclear fusion inside its core has ceased,… Continue reading →

Predicting Impact Events

Posted on April 4, 2015 by alyssasolarblog

In 1994, Comet Shoemaker-Levy 9 created a large impact event on Jupiter, giving the scientific community a greater sense of urgency in detecting possible impact objects before they reached Earth. These efforts to detect near-Earth objects, known collectively as “Spaceguard”, have enjoyed both successes and failures. For example, in 2008, the Catalina Sky Survey discovered … Continue reading Predicting Impact Events → Continue reading →
