Persevering through the trials of landing on Mars
Space rovers can cost a space program billions of dollars to make; in fact, Perseverance cost NASA 2.7 billion dollars. (Planetary) With that much money, time, and effort being put into a project, it makes sense that those behind it, wish to actually see their hard work successfully operate. For this to happen, the rover […] Continue reading

The Different Atmospheres in our Solar System
An atmosphere consists of the gases surrounding a planet. Atmospheres are created by volcanism (outgassing of volcanoes involves eruptions that take gasses from the earth’s interior and put them into the atmosphere), evaporation (of compounds such as water), and life (outgassing of carbon dioxide and oxygen). Life is an interesting component of an atmosphere as […] Continue reading

Blog 3: Climate Change
Astronomy has been around for many many years, as we have learned in class. Astronomy used to be a hobby for the wealthy, now it is an occupation for the smartest to learn about the universe we are in. One major facet that astronomers have observed and questioned is climate change. Recently, it has become […] Continue reading

Earth and Venus: Zach and Cody?
Scientists argue that Venus is earth’s astronomical twin for a number on reasons. Like Zach and Cody from the Disney Channel sitcom, The Suite Life of Zach and Cody their physical similarities and dependance on each other cannot be overlooked. Looking at Earth and Venus’ similarities, the similar diameter comes to mind. The diameter of […] Continue reading

The Sun’s Nuclear Fusion
The Sun has been producing a huge amount of energy for over 4 billion years through nuclear fusion. Nuclear fusion is the process by which the Sun converts mass to energy. Albert Einstein’s equation, E=mc^2, reveals that a little bit of mass has a huge amount of potential energy which indicates why the sun has […] Continue reading
Blog#3 Radioactive Decay
Our world is composed of elements all of which are made of protons, neutrons, and electrons. Protons are positively charged while electrons are negatively charged. Unstable (i.e., radioactive) atomic nuclei can become more stable after the emission of particles and energy, a process called radioactive decay. These emitted particles or energy (the latter emitted as […] Continue reading
Climate Change
We have all heard of climate change but what does it really mean? Climate change can be explained by the change in temperature and weather patterns that are occurring over long periods of time. Humans are at fault for climate change because we continue to burn fossil fuels like oil and coal. Burning fossil fuels […] Continue reading

Star Fuel – Nuclear Fusion
The sun has been around for 4.603 billion years, about one third of the entire duration of the universe. With a mass 330,000 times greater than Earth and a radius 108 times larger (source), the sun is a very massive object (though not that large when compared to other stars). Have you ever wondered whatContinue reading “Star Fuel – Nuclear Fusion” Continue reading
Rock Samples from Mars
Mars has been of interest because of evidence that it may have once supported life. NASA’s latest rover, Perseverance, has been sent to Mars to look for signs of ancient life. A big part of this endeavor is sending samples from Mars back to Earth for m… Continue reading

Nuclear Fusion For Rocket Propulsion
Nuclear fusion-where the nuclei of two atoms combine to establish a new atom-serves as the primary process that powers main sequence stars (like our Sun). For stars, nuclear fusion most commonly occurs with two hydrogen atoms fusing to form a helium atom. The result of such fusion processes is the output of great amounts of […] Continue reading
