The Planets Inspiring Art

Posted on March 8, 2023 by 88bw

Planets have always been a large source of inspiration for classical music composers, and there is probably no larger example than Gustav Holst’s Planets Suite. This work’s popularity has also reached the masses, and his music is known to have significantly influenced John Williams in his compositions for his film scores. What I find interesting […] Continue reading →

Kessler Syndrome and The Future of Satellite Use

Posted on March 8, 2023 by 88bw

The topic of spacecraft in our solar system made me curious about the use of satellites in our exploration of space. Although we hear more about the telescopes and imaging systems that we send far beyond Earth’s vicinity, the only low Earth orbit (LEO) satellite that I hear often about is the ISS. I wanted […] Continue reading →

Star Formation

Posted on March 8, 2023 by niqretnuh

When I was a kid, I thought stars were mysterious, distant, beautiful little things in the sky. I often pictured them as little beacons far out into the universe where the “spacemans” – a cute figment of my imagination – use to locate themselves once they get lost in the dark. A polar opposite of […] Continue reading →

The Λ-CDM Model

Posted on March 8, 2023 by dromalley

As this blog post presents me with much more freedom in topic, I’ve decided to discuss the most widely accepted theory for the origin and evolution of our universe: the Λ-CDM model. This model, named for the cosmological constant Λ which governs the accelerating expansion of space-time and for Cold Dark Matter, lays out a […] Continue reading →

The Unimaginable Nature of Space-Time

Posted on March 8, 2023 by jackdoyle25

Most depictions of the space-time continuum display it as a two-dimensional plane in three-dimensional space. In such a model, objects make indents in the plane based on their gravity, with more massive objects having larger indents. This model is helpful to display how gravity works, but it doesn’t capture the whole picture. The planar model […] Continue reading →

What would happen if an asteroid struck present-day Earth?

Posted on March 8, 2023 by Myles7235

We normally only see asteroids striking Earth in science fiction (what a relief!). NASA actually has an observatory whose sole purpose is to track both asteroids and comets and that appear like they might come close to Earth. During December of 2022, there were 5 asteroids that were placed on watch. Two of these asteroids […] Continue reading →

Nuclear Fusion

Posted on March 8, 2023 by niqretnuh

At noon on a hot summer’s day, have you ever wondered how the Sun acquires so much energy that the light coming from it, 150 million kilometers away, can bring so much heat that it even burns your eyes and skin? The answer lies in hydrogen fusion happening in the Sun’s core. In its initial […] Continue reading →

The Diversity of Terrestrial World Atmospheres: Venus, Mars and Earth

Posted on March 8, 2023 by theyounesadventure

Terrestrial planets’ atmospheres, including those of Venus, Earth, and Mars, are crucial to their general behavior and possible habitability. Many elements, including the planet’s distance from the sun, the makeup of its surface, and the presence of geological activity, all impact these atmospheres. The atmospheres of terrestrial worlds display a startling variation in behavior and […] Continue reading →
