The Death of the Sun
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
Almost InSight
InSight is short for Interior Exploration using Seismic Investigations, Geodesy and Heat Transport, and is NASA’s next big spacecraft. A little contrived, but its memorable. InSight is a Mars lander designed to study the inside of Mars: the crust, mantle, and core. It does so by measuring the planet’s seismology, heat flow, and precision tracking. … Continue reading Almost InSight → Continue reading

Measuring the Interior of the Earth
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
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
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

Blog Post 4
Image from Environment Blog It is important to understand that Climate Change is something that normally happens to planets. Earth will be around for a while. It does not matter if it goes through climate change; the Earth will remain. It is the humans and animals who will die off if the planet warms immensely. … Continue reading Blog Post 4 → Continue reading
Venus – Is it Habitable?
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

Where Did All of Mars’ Water Go?
It is currently known that Mars has only a fraction of the atmosphere that Earth has. This could be due to a number reasons ranging from its further distance away from the Earth and its smaller size in comparison to Earth and Venus, however, all terrestrial worlds had something that could have resembled an atmosphere … Continue reading Where Did All of Mars’ Water Go?
