Eclipses of the Past

Posted on January 29, 2022 by isaiandrade01

Due to advancements in technology, we can easily explain the scientific reasoning behind astronomical events such as lunar and solar eclipses. We understand solar eclipses occur in the new moon phase when the Moon passes between the Sun and Earth, appearing to cover the Sun and cast its shadow on the Earth. The opposite is […] Continue reading →

Junk in space: how do we deal with it?

Posted on May 4, 2021 by allyworthington

Junk floating through space, affectionately known as space junk, is dangerous to spacecraft and satellites, for obvious reasons. A team in Australia wants to use laser technology to track and destroy it. Adaptive optics is the technology that helps telescopes see stars without a twinkle, attributed to the Earth’s atmosphere. Adaptive optics sharpens images of … Continue reading Junk in space: how do we deal with it? → Continue reading →

NASA’s Picture of the Day

Posted on May 4, 2021 by mwdobson3

For the class Astronomical Experiences assignment, I was going to write about NASA’s May 3rd, 2021 Astronomy Picture of the Day. As I went to search for the daily image, I also found a PBS Nova video on the Mars mission involving Perseverance and I was hooked. Now that I can blog about anything forContinue reading “NASA’s Picture of the Day” Continue reading →

TESS: The Modern Exoplanet Finder

Posted on April 15, 2021 by mwdobson3

The Kepler mission marked a significant jump in exoplanet discovery when the space telescope was launched over 10 years ago. Since then, astronomers worked hard to research, develop, and design a more modern approach to discovering these distant and unknown planets. The solution was the Transiting Exoplanet Survey Satellite (TESS). TESS’s mission was to lookContinue reading “TESS: The Modern Exoplanet Finder” Continue reading →

Florida Asteroid Burning Up

Posted on April 15, 2021 by mwdobson3

On Monday April 13th, a small asteroid was spotted in the night sky off the east coast of Florida. One of my family members was all the way across the state on the western side of Florida and saw the asteroid’s fireball-like appearance as it passed by Earth over 26,000 km away. According to theContinue reading “Florida Asteroid Burning Up” Continue reading →

Death in Space

Posted on March 22, 2021 by allyworthington

It is no secret that space travel is a risky and dangerous endeavor for all involved. As of 2021, 19 astronauts (including cosmonauts) have died in in-flight accidents. Only one accident, however, occurred in space—over 100 kilometers above the Earth.  Three Soviets (called cosmonauts) were aboard the Soyuz 11 in June of 1971, which was … Continue reading Death in Space → Continue reading →

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 →
