For the first time in two decades, stargazers across the southern United States have been dazzled by colorful, undulating waves of light in the night sky. These so-called Northern Lights are vibrant displays of the interaction between electrons and ions emitted by the Sun and the Earth’s upper atmosphere. While this interaction usually occurs closer
To date, researchers have identified over 5,000 exoplanets in the Milky Way, a small fraction of the billions hypothesized to exist in our galaxy. Among them, researchers catalog so-called “Earth-like planets,” or planets with a similar size, structure, and distance from the Sun as Earth. While of great interest to modern astronomers, no conclusive evidence
When the International Space Station (ISS) reaches the end of its lifespan in 2031, where will it go? No options for major recycling exist in outer space, so when a spacecraft is decommissioned, there are only three “trash cans” available. The first is a so-called “graveyard orbit,” where spacecraft are blasted away from Earth into
I spent last summer far from Athens, Georgia, as an intern at the Caño Palma Biological Station in Costa Rica. A small station nestled in the lush jungle of eastern Costa Rica, Caño Palma conducts a variety of long-term wildlife surveying efforts, with the biggest and longest conservation project studying nesting sea turtles. Volunteers and
In late 2019, astronomers across the U.S. began to notice mysterious streaks of light passing through their images—clusters of the private company SpaceX's Starlink satellites. With 955 of these satellites launched so far, founder Elon Musk aims to create a “mega-constellation†of satellites in the low Earth orbit (LEO), designed to provide global broadband Internet
The term psychedelics, or hallucinogens, describes a class of drugs that produce significantly altered perception when ingested. Due to their ability to cause lasting effects on a user's mood and thought, some researchers believe they have therapeutic potential for treating difficult mental illnesses like depression, addiction, PTSD, and Alzheimer's, though only a few institutions currently
