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
As of 2020, the global consumption of energy is 580 million terajoules per year. Of this, 83.1% comes from fossil fuels like coal, oil, and natural gas, 4.3% comes from radioactive sources, and about 12.6% comes from renewable sources like hydro, solar, and wind. We have currently 50 more years of oil reserves left available,
People say that April showers bring May flowers, but have you ever considered meteor showers? We are in the midst of the annual Lyrid meteor shower, and it is one of the oldest meteor showers ever observed with sightings dating back to 687 BC. In 2022, the shower is expected to peak on the night
The History of the PhD While many students aim to earn their PhDs, few know the philosophical history of the degrees they are pursuing. The Doctor of Philosophy (PhD or DPhil) began as the degree awarded in recognition of advanced scholarship and acknowledging that recipients had expertise needed to teach at a university level. These
It is springtime! As spring prevails, all things in nature are suddenly adorned by myriads of colors. These myriads of colors inspire myriads of feelings. No other thing affects living beings' psyche as powerfully as colors. May that be love or war, spirituality or science, ascetism or fashion, poems or technology, colors seem to touch
What is a map? What does it REALLY represent? You might answer a map generally represents the relationships of locations. However, maps have evolved substantially in modern times. For example, modern genomics and cartography? While they might seem like different worlds, they actually share much in common. Both focused on a similar goal – spatial
Like many kids, I dreamt of becoming an astronaut; exploring distant planets and making contact with aliens. With a huge number of planets out there, it's hard to think we're all alone in this vast universe. But, as I grew as a scientist, my curiosity focused on a specific question: How can we find alien
Hearts, stars, horseshoes, clovers and blue moons, pots of golden rainbows and me red balloons! If you've ever eaten Lucky Charms cereal, you probably know this jingle and the tiny shapes of marshmallows it references. Interestingly enough, glycobiologists, or biologists who study the sugars that make up those tasty mallows, have their own Lucky Charm
‘Tis the season for stories of wintery magic. From Elsa and Frozone to their mythical grandfather, Jack Frost, there's no cooler gift than the power to let it snow at will, or shock a pond skate-worthy with a single touch. Little do we realize that these chilly abilities aren't limited to the realm of holiday
Everyone you've ever loved (or hated), everything you've ever held dear, every experience you've ever had – all of these have been confined to one tiny rock orbiting a giant ball of gas at 67,000 mph. From a distance, that tiny rock – Earth – is just a pale blue dot – or in the
In March 2018, a team of scientists led by Judd Bowman from Arizona State's School of Earth and Space Exploration and Alan Rogers from MIT's Haystack Observatory has done what many thought to be an impossible task. With a small radio antenna called EDGES (Experiment to Detect the Global Epoch of Recombination Signature) placed in
