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 →

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 →

The Titius-Bode law

Posted on March 7, 2023 by Rocket Man

Titius Bode’s law is a fascinating concept in astronomy that has been intriguing scientists for centuries. This law is a mathematical relationship between the distances of the planets in our solar system from the Sun. It was first formulated in the 18th century by Johann Daniel Titius and later popularized by Johann Elert Bode. According […] Continue reading →

The International Space Station

Posted on March 7, 2023 by sahilreddy2

The international space station is a collaboration that unites humanity to pursue the largest frontier, space. The ISS is the largest and most equipped space station humanity has ever had in space and provides opportunities to research exploration of space and how to help people back on earth. The ISS orbits the earth 386 kilometers […] Continue reading →

“How Stars Shaped Our Bodies and Our Home Planet”

Posted on March 7, 2023 by theyounesadventure

A portion of a nearby galaxy is illuminated in this Hubble Space Telescope image by the remnants of a once-explosive supernova. (Image credit: NASA/ESA/HEIC/Hubble Heritage Team) Nearly every component of our body and the planet we call home was created inside stars. Heavy atoms like carbon, nitrogen, and oxygen are produced from lighter elements like […] Continue reading →

Time Dilation and the Theory of Relativity

Posted on March 7, 2023 by Europa

With our totally unrestricted guidelines on Blog 4, I would like to make a bit of a deviation from the content of our course and discuss time dilation and the theory of relativity! When I first learned about time dilation, which refers to the difference in elapsed time as measured by different clocks due to […] Continue reading →

Blog #4 – Evidence for the Existence of Dark Matter

Posted on March 7, 2023 by constellationsarentreal

Dark Matter is a fascinating topic, yet we know so little about it. Regardless, a good amount of evidence exists that indicates dark matter is real. One pertains to the flatness of rotation curves for spiral galaxies at extended distances. The graph does not drop off, but rather, continues in (essentially) a flat rotation curve, […] Continue reading →
