Where are the Aliens?

Posted on November 25, 2024 by Henry Wang

One of the most common topics in science fiction (and conspiracy theories) is aliens. The coolest part is that they can be literally anything. There’s terrifying monstrous aliens like the Xenomorph from Alien and there’s much more lovable ones like E.T. It’s fascinating to think about life outside of the (relatively) small planet we call […] Continue reading →

Extrasolar Planets and How to Find Them

Posted on November 18, 2024 by Justinc

Extrasolar planets are planets that are found outside the Solar System. Stars are relatively easier to find than extrasolar planets as they are generally bigger and luminous (give off light). But planets, neither generate much light nor are they as big as stars so how do scientists find them? Well there are four main ways […] Continue reading →

Are There Planets Outside of Our Solar System?

Posted on November 18, 2024 by Matthew Marcus

The answer to this question is a resounding yes. Before the Copernican Revolution, back when many cultures still believed the Earth to be the center of the universe, the fact that these exoplanets exist would have been largely unthinkable. But today, well over 5,000 exoplanets have been discovered. When these distant bodies have eluded us […] Continue reading →

All About Comets

Posted on November 18, 2024 by Matthew Marcus

In popular media, comets are often depicted as huge balls of fire streaking across the sky. See Sozin’s Comet from Avatar the Last Airbender as an example: It may then be surprising to learn that asteroids are small, ice-rich bodies that are completely frozen for the majority of their life cycles. Comets tend to have […] Continue reading →

What Exactly is Pluto?

Posted on November 18, 2024 by Justinc

Did you know, Pluto isn’t considered to be a planet? Well you might’ve known that because of widespread media covering this information, but you may not know the reason why. There’s three qualifications of being officially considered a planet: it needs to orbit the sun; it needs to be big enough to be a spherical […] Continue reading →

Halley’s Comet

Posted on November 17, 2024 by Ian Vasquez

Halley’s Comet In 1705, Edmund Halley, an English astronomer, used Isaac Newton’s theories to chart the paths of 24 comets. In doing so he discovered that three comets that were seen in 1531, 1607, and 1682 were the exact same comet: Halley’s Comet. He then predicted that the same comet should appear again in the […] Continue reading →

Space Weather and Technology

Posted on November 17, 2024 by Michael

The field of space physics is becoming extremely important due to society’s increasing reliance on technologies that can be affected by space weather. Aviation, GPS, internet, and the power grid are just a few examples of infrastructure that may be damaged or even destroyed in a large-scale space weather event. Posing potentially lethal hazards, this […] Continue reading →

How Do Spacecraft Move?

Posted on November 17, 2024 by Henry Wang

We’ve all seen videos of spacecraft launching: 3, 2, 1, Blastoff! The main booster rocket burns a tremendous amount of energy to escape Earth’s gravity, reaching terminal velocity. Rocket Launch But when they enter space, this much force is wholly unnecessary, there is no gravitational field to escape, so how do spaceships move? The main […] Continue reading →

Giant Planets

Posted on November 17, 2024 by jasonljohnson465

Image from NASA In our Solar System, the giant planets are the outer four of the eight planets, Jupiter, Saturn, Uranus, and Neptune. In other words, they are the Jovian planets. However, these planets are split into two categories of giant planets: gas giant and ice giant. While all four of the planets are gaseous […] Continue reading →
