Many people may remember the last total solar eclipse that was visible from North America. It occurred on August 21, 2017. The next total solar eclipse that covers North America, and the only one for the next 20 years, will occur on April 8, 2024—almost one year from today. Total solar eclipses are a fascinating […] Continue reading →

Scientists often try to determine the age of various bodies in the solar system. The Earth and moon are around 4.5 billion years old, and the sun is around 4.6 billion years old. But how do scientists know this? And how confident are scientists in these ages? Scientists use radiometric dating to accurately date different […] Continue reading →

The sun produces energy via nuclear fusion—that is, it fuses two atoms into one, releasing a tremendous amount of energy in the process. The most common form of fusion in the sun is when hydrogen atoms are fused into helium—giving off energy in the process due to the lost mass. This is the most efficient […] Continue reading →

nuclear fusion

Posted on March 1, 2023 by Emma Williams

Have you ever wondered why the sun shines? It’s a question that has inspired centuries of astronomers to come up with a wide variety of explanations. It was once thought that the sun shone because of chemical combustion, but we now know that there is nowhere near enough oxygen for that process to have sustained […] Continue reading →

Astronomy is a science. This means that in astronomy we make predictions, test hypotheses, and use findings to continuously build and refine our theories. Interestingly, astronomy was very likely the first science. Humans, ever since the ancient civilizations, have looked to the sky and pondered its mysteries. What use would such people have in astronomical […] Continue reading →

Barophiles

Posted on April 30, 2022 by solarelizabeth

The barophiles we have found are tiny organisms, usually bacteria, living in areas with intense pressure. They are found on ocean floors where pressure can reach about 400 atm. For reference, the atmospheric pressure at sea level is 1 atm. Some barophiles known as obligate barophiles cannot survive in low pressures. The barophile Halomonas salaria […] Continue reading →

In 2006, Pluto was taken off the list of planets, leaving our Solar System with just 8 planets. This demotion occurred 76 years after Pluto was initially added to the list of planets. This decision by the International Astronomical Union (IAU) defined what objects could be classified as a planet. An object needs to be […] Continue reading →

The Evolution of Earth’s Atmosphere

Posted on March 22, 2022 by AndreaS

So many of Earth’s features today, from our blue sky to life itself, depend on the atmosphere surrounding the planet, but it has taken billions of years to evolve to where it is today. This post will explore the evolution and progression of Earth’s atmosphere as well as the processes that led to these changes. […] Continue reading →

Many people have traveling to see the Northern Lights on their bucket lists. This unique phenomenon typically occurs near the Arctic Circle, with places like Finland advertising tourist expeditions to see them. The Northern Lights, otherwise known as aurora, occur when ions from solar winds collide with atoms of different elements (oxygen, nitrogen) in Earth’s […] Continue reading →

Nuclear fusion reactions power stars. In nuclear fusion, 2 atoms’ nuclei merge and form a heavier single nucleus. The leftover mass becomes energy. In stars like the Sun, this is generally the transformation of Hydrogen to Helium (proton-proton chain). Other, more massive stars, use the CNO cycle (uses more elements) to accomplish energy transformation. The […] Continue reading →
