A History of Observing the Sun

Posted on March 22, 2021 by mwdobson3

Kevin Durant, a two-time NBA champion, once tweeted: “I’m wondering how do these people kno what’s goin on on the the sun.. ain’t nobody ever been.” Like his tweet from 2010, I too wondered how humans have been able to study the Sun’s surface and what discoveries have been made to determine the surface’s characteristics.Continue reading “A History of Observing the Sun” Continue reading →

Radioactive Proof of the Earth’s Age

Posted on March 20, 2021 by jagobillot

Radioactivity of elements starts with an unstable elemental isotope. An unstable atom on radioactive elements carries too many protons or neutrons, and eventually, it must expel energy from the atom, and become an entirely new stable element through the process of beta decay. This process, for every unstable atom, is completely spontaneous and there isContinue reading “Radioactive Proof of the Earth’s Age” Continue reading →

Spacecraft in the Milky Way

Posted on March 11, 2021 by gracelearnsspace

Since 1958 over 250 spacecraft have entered our solar system to explore and have given a little bit more insight to the huge universe around us. One of those spacecraft, Parker, is on a mission to get seven times closer to the Sun than any other spacecraft before. Parker was launched in 2018 by the […] Continue reading →

The Thirty Meter Telescope

Posted on February 26, 2021 by mwdobson3

Currently, the largest single-aperture telescope in the world, the Gran Telescopio Canarias, spans 10.4 meters (about 32 feet). This telescope can see 500 million light-years deep into space, which was thought to be impossible out of a single, segmented reflecting telescope until it was built in 2006. While 10.4 meters is large, astronomers worldwide feltContinue reading “The Thirty Meter Telescope” Continue reading →

Ephemerides: An Astronomer’s Excel

Posted on February 5, 2021 by mwdobson3

From the first time I observed lunar eclipses to now understanding how they occur, I have always wondered how astronomers are able to predict every piece of information about them years in advance. Also, in the bigger picture, I did not know how astronomers knew where the planets and stars were in our Solar SystemContinue reading “Ephemerides: An Astronomer’s Excel” Continue reading →

Juno – Spacecraft, Roman Goddess, and….Lego Minifigure?

Posted on March 16, 2020 by alexsolarsystem

Currently orbiting Jupiter is a small satellite that goes by the name of Juno. This small spacecraft was launched in 2011 and was tasked with uncovering as much as possible about Jupiter and its mysterious history. Its main mission is to measure the composition, gravity field, and magnetic field of Jupiter while simultaneously looking forContinue reading “Juno – Spacecraft, Roman Goddess, and….Lego Minifigure?” Continue reading →

Parker Solar Probe: Understanding Coronal Dynamics

Posted on March 15, 2020 by Dan Pitagora

Launched on August 12th, 2018, the Parker Solar Probe will make the closest approach to the Sun in history. Over a time period of roughly seven years, PSP will use Venus for gravitational assist to make successively closer approaches to the Sun at distances as small as 4 million miles from the sun’s surface. PSPContinue reading “Parker Solar Probe: Understanding Coronal Dynamics” Continue reading →

The Telescope of the “Future”

Posted on March 15, 2020 by 2xchampions

Living up to its futuristic shape, James Webb Space Telescope is indeed a telescope of “future”: NASA has delayed its launch so many times that this telescope seems to only exist in the future. Jokes aside, the JWST carries with itself enormous scientific potential: it is supposed to be 100 times stronger than the HubbleContinue reading “The Telescope of the “Future”” Continue reading →

Spectroscopy and Space

Posted on February 9, 2020 by gabezharovtothemoon

Although Isaac Newton’s most famous contributions to astronomy are his laws of motion and gravitation, which he published in Principia, Newton also founded modern spectroscopy by publishing his second work, Opticks. Spectroscopy is an essential tool for astronomers because it allows them to not only analyze the presence of certain chemical elements, but also physicalContinue reading “Spectroscopy and Space” Continue reading →

The Daniel K. Inouye Solar Telescope!

Posted on February 9, 2020 by oliviabastasch

From Earth, the Sun appears to be just a glowing yellow orb. However, the Daniel K. Inouye Solar Telescope in Hawaii has captured new images of the Sun that reveal its violent and explosive nature. This massive four-meter telescope has the technological capabilities that are necessary to better understand the Sun’s magnetic field and outer […] Continue reading →
