Lack of Cratering: Io and Europa

Posted on February 28, 2023 by willems49

During class, we have discussed magnetospheres, tectonics, geological activity, and their relation to the cores of the “Big Five”: Earth, Venus, Mercury, the Moon, and Mars. Specifically the moon has very obvious cratering across its entire surface, and its craters remain intact for billions of years. This is due to it not having an atmosphere […] Continue reading →

M45 – The Seven Sisters

Posted on February 28, 2023 by 7smessier45

Hey, y’all, and welcome back!  Today, we’re taking a quick jaunt outside our solar system to visit the Pleiades. This grouping of stars–commonly referred to as Messier 45 (M45)–is one of my favorite observables and can be best viewed in January–but the cluster is easily visible from late fall through the winter. The cluster is […] Continue reading →

What will happen to our solar system when we collide with Andromeda?

Posted on February 28, 2023 by Melanie Marszal

You may be familiar with Andromeda, our closest neighboring galaxy. You may have also heard that Andromeda and our Milky Way are moving towards each other. But what will happen to Earth and the rest of our solar system when these two galaxies collide? Will Earth even still be around by then? The answer to […] Continue reading →

Dark Matter

Posted on February 27, 2023 by zws42

In studies of galaxies and star clusters, astronomers have found that many of these bodies appear to move in ways that don’t reflect the amount of visible matter in the system. For instance, some galaxies appear to orbit much faster than they should be based on the amount of stuff we can see within them. […] Continue reading →

Nuclear Fusion

Posted on February 27, 2023 by zws42

Nuclear fusion is the process that powers our sun, as well as all the other stars in the Universe. At the most basic level, nuclear fusion is the combination of two light atomic nuclei to form a heavier one along with a release of energy. This reaction is governed by Einstein’s E=mc^2 equation, where some […] Continue reading →

Comparing the Atmospheres of Mercury, Venus, Earth, and Mars

Posted on February 27, 2023 by Melanie Marszal

We may not think much about the presence of Earth’s atmosphere in our day-to-day lives, but it has an immense impact on us. Earth’s atmosphere contains the oxygen we need to breathe, protects us from many of the Sun’s harmful ultraviolet (UV) rays, helps stabilize the Earth’s temperature, and is responsible for weather patterns. If […] Continue reading →

Solar Flares and the Carrington Event

Posted on February 26, 2023 by sydneyastr2110

We heard a little bit about the Carrington Event in class, and I wanted to know more about it. A solar flare is essentially a burst of energy on the Sun which sends electrified gas and subatomic particles toward Earth. In 1859, there was an abnormally large solar flare caused two geomagnetic storms known as […] Continue reading →

The Coolest Telescope

Posted on February 15, 2023 by Liam Prescott

The James Webb telescope, unveiled on December 25 2021, is by far the coolest telescope. Webb has the power to view infrared light rays from exoplanets that are potentially habitable. Also the innovative technological achievement can better observe our own solar system and the first galaxies that were formed 13.5 billion years ago. It has […] Continue reading →

Evidence for Understanding

Posted on February 13, 2023 by dougkyles422111

I want to talk about an aspect of light that doesn’t make the most sense to me, and that is how we receive it. Thinking about sight abstractly, we cannot really comprehend at all times what we are seeing are particles of light. To us, our visual environment is our reality. Learning about how the […] Continue reading →

Blog 2 – Tides: my thoughts from the anime Avatar: the Last Airbender

Posted on February 13, 2023 by niqretnuh

One of my favorite poetic interpretations of tides comes from the anime “Avatar–the last airbender”. In the episode “The Siege of the North”, the root of the mysterious power of “water-bending” is explained to stem from the moon, and the power of tides. The goddesses “tui (推)” and “la (拉)” (“push” and “pull”) directs the […] Continue reading →
