30 years of Hubble: Images and discoveries that shaped astronomy

April 24th, 2020 was the 30th anniversary of the launch of perhaps the most famous telescope: the Hubble Space Telescope. Orbiting the earth, this telescope has changed the way astronomers and the public alike view the universe. With over 1.4 million observations, providing data for more than 16,000 peer-reviewed scientific papers, Hubble has exceeded expectations…

Why Worry about James Webb?

Posted December 25, 2021 by Jennifer Sieben

[Six gold, hexagonal mirrors are arranged on a mount, ready to slide into a large chamber. A man is seen standing in front, looking much smaller than the mirrors and the chamber.

If everything has gone according to schedule, the James Webb Space Telescope (JWST) launched on December 22 and is currently on its way to its final orbit. JWST is designed to be a revolutionary telescope, building on the accomplishments of both the Hubble and Spitzer Space Telescopes. With its infrared instruments, it will enable us to see stars that were previously hidden by dust and to even detect water in the atmospheres of exoplanets. Its huge mirrors will help us collect more light to study the very earliest galaxies and uncover more information about how our universe was formed. Yet, the JWST will still give us gorgeous images of the universe, like Hubble does…

Stellar ghosts: Understanding supernovae

Posted October 30, 2021 by Jennifer Sieben

Are ghosts real? Spooky figures in a haunted house, maybe not. But if you’re looking for energy left behind after death, you may want to turn your gaze to the stars. Stars may not be conventionally “alive,” but they do have a lifecycle and part of that lifecycle includes death. In rare cases, that death releases a spectacular amount of energy in a supernova explosion…

Eclipses and solar system geometry

Posted September 25, 2021 by Jennifer Sieben

[The sun rises behind the United States Capitol Building during a partial solar eclipse.]

Eclipses are a marvel of our Solar System, and it’s only due to the precise alignment of the Sun-Earth-Moon system that they happen at all. This marvel of geometry is worth exploring to understand the different types of eclipses and how often they occur. There are two types of eclipses: solar and lunar. Both rely on light from the Sun being blocked and casting a shadow, but what makes them different is where the human observer is positioned. Total solar eclipses are the most stunning of eclipses. This is when the Moon completely covers the Sun and the world is plunged into near darkness. However, these events are rare, especially if you cannot travel to see one…

Until I collapse: Arecibo’s more than 50 years of discoveries

Posted July 3, 2021 by Guest Contributor

Famous for its appearances in movies and television including GoldenEye (1995), Contact (1997) and an episode of The X-Files (“Little Green Men”), the Arecibo telescope is a massive 305m (1,000 ft) radio telescope.  Built into a natural karst sinkhole on the island of Puerto Rico in 1963, it was in fact the largest single dish telescope in the world until China completed its Five-Hundred-Meter Aperture Spherical Telescope (FAST) in 2016.  Unfortunately for the astronomical community, Arecibo suffered severe damages this year that led to its eventual collapse…

Finding the Right Question

Posted April 3, 2021 by Jennifer Sieben

[Portrait of Dr. Songhu Wang.]

Imagining life on other planets is usually the work of science-fiction authors, but increasingly it is becoming the work of current astronomers. Although it had been theorized that there existed other planets outside of our solar system, exoplanets were only confirmed in the late 1980s. The field exploded when the Kepler space telescope started finding hundreds of exoplanets. A rich field of study was born…

The science behind meteor showers in Animal Crossing

Posted August 15, 2020 by Jennifer Sieben

[Animal Crossing player character bowing their head with eyes closed as they

Animal Crossing has proven again and again to be an exquisitely well-designed game and has surprised many with its excellent representation of scientific concepts. Many players have written about the punnet squares of flower breeding, and others have made videos about all the animals in Blathers’s museum (even the bugs!). However, I’d like to turn your attention skyward. Let’s take a look at the meteor showers that happen above your island…

Science without a Degree: What is Citizen Science and How to Get Involved

Posted April 11, 2020 by Jennifer Sieben

[repeating illustrations of a laptop showing a bar graph, a microscope, and a magnifying glass.]

Louis Pasteur once said, “Science knows no country, because knowledge belongs to humanity, and is the torch which illuminates the world.” The act of doing science should not, and cannot, be confined to people in lab coats with multiple degrees squinting at computer screens and scribbling on whiteboards. Exploring the natural world around us should be something everyone can take part in, and that’s what citizen science is…

What’s up with leap years?

Posted February 29, 2020 by Chloe Holden and Lana Ruck

Today is February 29. Unlike every other day in the year, this day only shows up in the calendar once every four years… but why? To understand this, we’re going to use a little bit of history and astronomy to get to the calendar that most of the world uses today. First, let’s talk about… Read more »
