Venus’s atmosphere is very, very dense. It is composed of about 96% carbon dioxide, 3.5% nitrogen, and trace amounts of other gases, including sulfur dioxide. Although Earth’s atmosphere is composed of over 75% nitrogen, Venus’s atmosphere is so dense that the 3.5% of its atmosphere that is composed of nitrogen has around 4 times the … Continue reading The Atmosphere of Venus → Continue reading → Continue reading
On August 12, 2018 the Parker Solar Probe was launched. The mission of this probe is to investigate activity in the Sun’s corona in order to provide us with information that can help us understand more about the star and Earth’s connection to it. Analyzing the data being sent back will allow scientists to potentially … Continue reading Understanding Our Sun → Continue reading → Continue reading
Considering all the horrible ways that either humans or otherwise could end life on Earth, the idea of inhabiting another world seems pretty nifty. The only issue with that is we need oxygen and for our soft squishy skin to not get fried by intense sunlight. So, the prospects of getting off our planet for … Continue reading Terraforming Continue reading → Continue reading
In 2003, NASA launched the Mars Exploration Rover mission, dropping the Spirit and Opportunity rovers on Mars in January 2004. Although their planned mission lifetime was 90 days, both rovers far exceeded this. Spirit lasted 20 times longer than this, traveling almost 5 miles before sending its final message to Earth on March 22, 2010. […] Continue reading → Continue reading
You may be familiar with the Periodic Table, which lists every type of atom (referred to as ‘elements’) in the universe. Each of the elements is formed by combining subatomic building blocks in different ways. One of the most important element-creating events in the Universe was Big Bang nucleosynthesis, the period about 10 seconds to … Continue reading Stars: How to Make Just About Everything → Continue reading → Continue reading
The Aurora Borealis is one of the most beautiful phenomena in the world, but how does it actually come to be? It all starts with the Sun. As the Sun rotates on its axis, magnetic field lines are twisted and jumbled around which cause sun spots, or regions on the suns surface of cooler temperature … Continue reading Aurora Borealis → Continue reading → Continue reading
When I was younger, I was always fascinated by the amazing strides of space exploration technology. Voyager 1 and Voyager 2 were the pinnacle of human achievement in my opinion. It has been a long time since I reviewed their journey. I watched a YouTube video summarizing the achievements of these two amazing space probes. … Continue reading Updates on the Voyager Missions → Continue reading → Continue reading
Geologists and neutrino physicists are currently striving to calculate the amount of radioactive power remaining in Earth’s core. Why does this matter? The hot core of the Earth is known to provide the driving force behind plate tectonics, a process that constantly refreshes the crust of the Earth and creates many of the geological features … Continue reading How much is left in the tank?

It is commonly believed that in locations of high altitudes, such as on the top of a mountain, the lower temperatures experienced are a caused by the lower atmospheric pressure that is present. However, this is not entirely the case. While the change in elevation is partially responsible for the decrease in temperature, the presence … Continue reading Altitude and Temperature → Continue reading → Continue reading
The Sun is the star at the center of the Solar System and is a nearly perfect sphere of hot plasma. Its diameter is about 1.39 million kilometers (864,000 miles) – 109 times that of Earth – and its mass is about 330,000 times that of Earth. The Sun accounts for about 99.86% of the total mass of the Solar System and its … Continue reading Sun Facts → Continue reading → Continue reading
