Kuiper Belt Objects…What Are They?

Posted on April 9, 2018 by terranojm

Kuiper Belt Objects are unique in that they have different compositions than most asteroids and different orbits than most comets. This has led astronomers to contemplate the identity of Kuiper Belt Objects. Surprisingly, the answer isn’t so clear. Asteroids are mostly composed of rock while comets are mostly composed of rock and ice. Most Kuiper … Continue reading “Kuiper Belt Objects…What Are They?” Continue reading →

The Trojans and Greeks

Posted on April 3, 2017 by pkunetz97

As was recently discussed in class, there are two clusters of asteroids ahead of and behind Jupiter known as the “Trojans” and the “Greeks”. The first one to be discovered was an asteroid now known as “Achilles”, a hero who fought on the Greek side of the Trojan War. The Greeks are all slightly ahead […] Continue reading →

Asteroids: Death, or Life?

Posted on April 10, 2016 by astr2110geoffren

Just hitching a ride Most people don’t think of asteroids as the bringer of life to Earth. Actually, for many, it’s the exact opposite. When someone says asteroids many people automatically think about mass extinctions, specifically the extinction of the dinosaurs (which was caused by a large asteroid). However, there is a theory called panspermia which […] Continue reading →

Meteorite Chemicals Form Building Blocks of Life

Posted on April 29, 2015 by pMurs

A research team at the Tuscia University in Italy has released a study suggesting that the kick-starter for early life may have hitched a ride to earth on the backs of meteorites. Formaldehyde, an organic compound that is posited as the key building block for early microbial life, is known to exist in the centers […] 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 →

The K-T Extinction: Asteroids and Atmospheres

Posted on March 15, 2015 by dillonkoval

Let’s talk about the dinosaurs. Everyone has heard the story: Dinosaurs roamed the Earth ages ago until an asteroid hit and caused all of them to go extinct. There was a huge amount of dust thrown up into the atmosphere which blocked out the Sun and caused plants to die. This set off a chain […] Continue reading →

The Solar System: An Overview

Posted on April 20, 2014 by hollyreichert

This year I learned details about the Solar System that I did not even know existed.  Before astronomy this year, I did not know about the Kuiper Belt.  I thought we only had the Asteroid Belt.  I knew that comets and asteroids were different– but I was not sure what the difference was.  Now I […] Continue reading →

Asteroids and Orbital Resonance

Posted on April 9, 2014 by dhbrett

Why is there an asteroid belt in our solar system, and why is it located where it is? The main asteroid belt is located between Mars and Jupiter, and it was formed by an effect called orbital resonance. Orbital resonance occurs when the gravity fields of two objects align. Because Jupiter was so large during … Continue reading Asteroids and Orbital Resonance → Continue reading →

Ceres, the Inner Solar System Dwarf Planet

Posted on April 8, 2014 by Chad F

Ceres was discovered in 1801 and is the largest object in the asteroid belt between Mars and Jupiter.  It was originally classified as a planet, but has since been demoted to a dwarf planet.  It is thought to have an icy mantle and a rocky core with the possibility of a subsurface ocean and thin atmosphere. […] Continue reading →

Asteroid Mining

Posted on March 15, 2014 by philipapelles

There are millions of asteroids in our solar system, and they are more valuable than most people think. When I thought of asteroids in the past, I thought of grey rocks that were uninteresting and dull. However, after learning about asteroid mining and the potential benefits asteroids could provide Earth, I re-evaluated my standpoint. It… Continue reading →
