Gravity Waves

Posted on March 11, 2019 by Jonathan Roberts

Venus is the unfortunate victim of a runaway greenhouse effect. Not only does this make the planet uninhabitable, it also causes a tremendous degree of difficulty in observing the planet’s surface. However, there are many interesting things to gain from Venus by just looking at the atmosphere, including a massive gravity wave. Gravity waves in … Continue reading Gravity Waves → Continue reading →

Nuclear Fusion in the Sun

Posted on March 11, 2019 by richardtli

Nuclear fusion is the process in which the Sun and all other stars generate energy through the combination of light atoms into heavier ones. The nuclear fusion in most stars is carried out in proton-proton fusion. In the first step, two protons fused together to create a proton-neutron core and emitting a neutrino and positron. … Continue reading Nuclear Fusion in the Sun → Continue reading →

An Artificial Sun

Posted on March 11, 2019 by Campbell Flower

In November of 2018, Chinese scientists announced their work on an artificial sun. Their goal is to develop the same nuclear fusion process that occurs within the sun (the conversion of hydrogen into helium) on Earth to ultimately create a source of unlimited clean energy. One of the biggest challenges of this project is to … Continue reading An Artificial Sun → Continue reading →

The Age of a Rock

Posted on March 11, 2019 by Aaron Molotsky

In the grand scheme of things, one can forget about how everything little thing that exists in our Universe has an age. While we consistently talk about planets and stars having ages of billions of years, we sometimes forget to think about not only how the rocks and geographical formations on Earth are formed but … Continue reading The Age of a Rock → Continue reading →

Finding Nuclear Fusion

Posted on March 11, 2019 by Aaron Molotsky

Before the advent of Modern Science and its ability to explain natural phenomena relatively well, we had no idea how the Sun actually worked. Scientists had no idea that the Sun was just a giant ball of really hot gas that’s able to generate light using its own mass. However, over the course of time … Continue reading Finding Nuclear Fusion → Continue reading →

Retrieving Voyager 1 – A Rescue Mission

Posted on March 11, 2019 by Jonathan Roberts

In 1977, NASA launched Voyager 1 to study the far reaches of our solar system. The program was a tremendous success: not only did the probe gather useful information about Jupiter and Saturn, it also captured the first detailed images of their moons (including a flyby of Titan, Saturn’s largest moon). Even now, after Voyager … Continue reading Retrieving Voyager 1 – A Rescue Mission → Continue reading →
