The Diversity of The Solar System

Posted on April 30, 2021 by thestarstudent

After being in ASTR 2110, my biggest takeaway is probably the intense diversity that exists in our own solar system. Everything here is all made from the same protoplanetary disk, yet we have small terrestrial dwarf planets, medium sized terrestrial planets, and gas giants. How can the same material that made Venus’ thick atmosphere alsoContinue reading “The Diversity of The Solar System” Continue reading →

Extremophile Viability in Space

Posted on April 30, 2021 by thestarstudent

In 2014, a group of scientists studied the viability of four different types of extremophiles in space-like conditions. These conditions that replicated an experience on Mars included extreme low temperatures, levels of UV radiation, humidity, and low pressure. The extremophiles in the experiment were Sulfolobus solfataricus from Solfatara volcano in southern Italy that can liveContinue reading “Extremophile Viability in Space” Continue reading →

The Northern Lights

Posted on April 28, 2021 by gracelearnsspace

The northern lights are one of Earth’s beautiful sights that everyone wants to see. However, little people actually know how they occur. The northern lights, which are aurora, are caused by electrified gas from the Sun getting caught by Earth’s magnetic field which leads to the North and South poles. These particles from the sun […] Continue reading →

Explore Giants

Posted on April 28, 2021 by kjackson1456

Earth may seem special to us, but it is just one of a near countless number of planets in our universe—a rather small one at that. Giant planets are those planets that dwarf Earth in size. They are gaseous bodies, meaning that they are primarily composed out of a swirling combination of gasses held togetherContinue reading “Explore Giants” Continue reading →

It might surprise you to know that the sun is over 90 million miles away from us! That’s right: something that far away is able to provide us with life-saving light and warmth. A process called nuclear fusion is responsible for the sun’s tremendous heat and brilliant shine. Though it may look different from otherContinue reading “ExploreSol” Continue reading →

The Fermi Paradox

Posted on April 27, 2021 by gracelearnsspace

The Fermi Paradox is the paradox that while there are probably other intelligent life forms in the Milky Way, none have have made any communication with Earth. Since Earth is a younger planet of the Milky Way, if intelligent civilizations existed they would likely be much older, meaning they would have the technology to communicate […] Continue reading →

Blog 6 Aristotle’s cosmology

Posted on April 23, 2021 by zvrec

In this blog, I would like to introduce Aristotle’s model of the universe. The cosmic theory from Aristotle is clearly wrong from the view of modern science. However, before modern astronomy was developed, Aristotle’s ideas about our world dominated people’s belief for thousands of years. It was embraced by scholars, philosophers, and religious leaders asContinue reading “Blog 6 Aristotle’s cosmology” Continue reading →

Galaxies

Posted on April 20, 2021 by 20harriganc

Galaxies are cosmic Islands of stars, gas, dust and dark matter. They span across very long distances and they are held together by gravity. There are multiple types of Galaxies as shown in the the photo above. The word galaxy is derived from the greek word “galaxias”. It means milky, which is a direct referenceContinue reading “Galaxies” Continue reading →
