Where did all the dinosaurs go?

Posted on April 7, 2016 by sarabkeller

I think one of the more fascinating topics in Earth’s past is the mystery of the dinosaurs. They were here 65 million years ago (for a shockingly long time—if you remember, they were here for almost a week in the “calendar” of the universe!) and then suddenly disappeared. So, what happened to them? It is […] Continue reading →

So Extra…

Posted on April 7, 2016 by Sofia

Extrasolar planets are very important to our study of the universe. The idea that there are planets that orbit other stars the way we orbit the Sun changes our entire perspective of how the universe operates. There are many challenges with detecting extrasolar planets, but once they are found they can provide us with a … Continue reading “So Extra…” Continue reading →

Io

Posted on April 7, 2016 by lawlorsolarsystem

Io is Jupiter’s third largest moon. What is notable about Io is that it is the most geologically active body in the entire Solar System. It is extremely volcanic, and is the only body other than Earth that we  have observed with active volcanism. The volcanic activity occurs because Io is greatly affected by tides […] Continue reading →

The Mystery of “Hot Jupiters”

Posted on April 6, 2016 by alecsolarsystem

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 →

Jupiter’s Less Popular Moons

Posted on March 28, 2016 by hallesolar

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 →

Hubble

Posted on March 15, 2016 by imanig625

The Hubble telescope, which has been orbiting Earth for over 25 years, views the universe with a completely different perspective than what we can see on Earth. While the telescope is not necessarily responsible for amazing images like this one, it can be given credit for other just as powerful views of the universe. Its… Continue reading →

Dust Devils on Mars

Posted on March 15, 2016 by Gabi Grys

  The ~spooky~ imagine below is not, as one may initially believe a charcoal sketch drawing of branches against the night sky (Just me? Okay). Instead, the image below shows tracks on the Martian surface from dust devils. Dust devils, strong whirlwinds comparable to tornadoes, leave beautiful dark lines and swirls on the Martian surface.

Sun: Where do you see yourself in 5 billion years?

Posted on March 15, 2016 by samihahplanet

Currently, our nearest and dearest star is at the ripe middle age of about 4.5 billion years old. This means that the Sun is a “main sequence star,” so it converts the hydrogen in its core to helium. However, about 4 billion years from now, the Sun will being to transition to a red giant, […] Continue reading →
