A Voyager in the Solar System: The Story of the Voyager I and II

Posted on March 17, 2018 by jonahastroblog

Two twins. Exploring where no other spacecraft has ever explored before. This was the goal that NASA set out to accomplish when they launched the Voyager spacecrafts. At least, this is what their missions came to be. However, it is not just the missions themselves that make them famous, but also what they carry for… Continue Reading → Continue reading →

Fusion vs. Fission

Posted on March 17, 2018 by dempsy

The nuclear energy can be generated in two ways – fusion and fission. Both fusion and fission energy are generated by altering atoms. What is the difference between fusion and fission? And which way will generate more energy? As the word “fission” means separate a thing into different parts, nuclear fission means releases energy by … Continue reading Fusion vs. Fission → Continue reading →

The Death of the Sun

Posted on March 17, 2018 by Caroline Henning

Unfortunately, our Solar System will not exist forever–our Sun’s lifespan is indeed finite. Sunlike stars stay on the main sequence for approximately 10 billions years. In other words, this is about how long the Sun will shine. The Sun is about 4.6 billion years old, so we may expect about 5.4 billion more years of … Continue reading The Death of the Sun → Continue reading →

Measuring the Interior of the Earth

Posted on March 17, 2018 by lin0214

It is very hard to drill to the deepest part of the Earth. However, there are some indirect measurements that allow us to know limited information about the interior structure of the Earth. One of those is the measurement of seismic waves. By knowing the characteristic of seismic waves, we are able to identify the properties … Continue reading Measuring the Interior of the Earth → Continue reading →

Nuclear Fusion

Posted on March 17, 2018 by samssolarsystem

Nuclear Fusion refers to the nuclear reaction in which atomic nuclei of low atomic number elements fuse to form a heavier nucleus.  This reactions releases energy and is how the sun and other stars generate light and heat.  Energy is produced during the smashing of the lighter atoms, which is most easily achieved on Earth … Continue reading Nuclear Fusion → Continue reading →

Nuclear Waste: a closer look

Posted on March 17, 2018 by Jeanie Zeng

Every year, approximately 20% of the energy generated by the United States comes from nuclear power. Throughout the years, our consumption of nuclear power has brought with it over 90,000 metric tons of nuclear waste. 97% of nuclear waste in the world has been classified as low- or intermediate- level waste (LLW or ILW) while the … Continue reading Nuclear Waste: a closer look → Continue reading →

Venus – Is it Habitable?

Posted on March 17, 2018 by hellouniverse1234

When you think about humans moving to other planets, your train of thought probably leads you to think about Mars. Sending spacecrafts to Mars, talks of terraforming Mars, the works. But another planet that has been a subject of many science fiction stories is none other than Earth’s sister planet: Venus. Venus’ surface is hostile. […] Continue reading →
