Where are the extraterrestrials?

Posted 10 months ago by Alison Klesman

By Richard Talcott While discussing the possibility of intelligent life in the universe over lunch with his fellow scientists, Nobel Prize-winning physicist Enrico Fermi asked the simple question: “Where are they?” The line came to be known as the “Fermi Paradox,” and the argument boils down to this: If the universe is teeming with life, and some reasonable percentage of that life has developed advanced technology, then these civilizations should have populated our cor...

How the Sun creates asteroids

Posted 10 months ago by Alison Klesman

By Richard Talcott From its position at the center of the solar system, the Sun spews harsh radiation and energetic particles whose effects are felt well beyond the realm of the planets. In most cases, these emissions are forces of destruction, but not always. On Wednesday at the 49th annual meeting of the Division for Planetary Sciences in Provo, Utah, Apostolos Christou of the Armagh Observatory and Planetarium in Northern Ireland showed how sunlight can be creative. Christou and his team ...

Small bodies loom large

Posted 10 months ago by Alison Klesman

By Richard Talcott As their name implies, planetary scientists spend much of their time studying the biggest bodies in the Sun’s family: the planets and their large moons. But on Tuesday at the 49th annual meeting of the Division for Planetary Sciences in Provo, Utah, researchers turned some of their attention to the smaller bodies in our solar system. Vishnu Reddy of the University of Arizona reported on his team’s observations of Earth’s quasi-satellite, 2016 HO3. Althoug...

Saturn takes center stage

Posted 10 months ago by Alison Klesman

By Richard Talcott While most of the astronomical world spent Monday celebrating the incredible discovery of two neutron stars merging, planetary scientists held their own celebration. On the first day of the 49th Division for Planetary Sciences meeting in Provo, Utah, scientists with the Cassini mission to Saturn reported on the latest discoveries to come from the spacecraft before it plunged into the ringed planet’s atmosphere a month ago. During Cassini’s “Grand Finale,&...

Could Planet Nine really exist?

Posted 10 months ago by Jake Parks

All right, I know. I was extremely skeptical too. And I’m still not completely sold. But I have to admit that the evidence is mounting. There just may be a so-called Planet Nine lingering in the dark, icy graveyard that is our outer solar system. And if it’s there, its subtle influence could help explain some of our solar system’s most mysterious characteristics — like the highly elliptical orbits of comets and asteroids, or the slight tilt of the plane of our sol...

One asteroid at a time? Nah.

Posted 10 months ago by Jake Parks

Asteroids are some of the oldest and most undisturbed objects in our solar system. These miniaturized, rocky worlds have been—for the most part—peacefully orbiting the Sun since the formation of the solar system some 4.5 billion years ago. It’s estimated that over a million of the floating boulders are crowded together in the main asteroid belt, located about halfway between Mars and Jupiter. And every once in a while, one of them gets bumped out of orbit. But, over the cour...

Explore more than 200 of the Red Planet’s amazing features By Leah Froats Our human fascination with the Red Planet traces back to the 19th century, carrying on unwavering to the modern day. Of course, when the first Mariner spacecraft visited Mars in the 1960s, it found a desolate world. Ideas about martians faded away. But numerous spacecraft over the past 50-plus years, including orbiters, landers, and rovers, have uncovered an amazing planet that tells us a lot about the solar syst...

Guest Blog: The ExoLife Finder: A next-generation telescope for imaging exoplanets

Posted 11 months ago by Alison Klesman

By Jake Parks A few years back, a group of astronomers put forth a proposal for a beast of a telescope—The Colossus. At 77 meters in diameter, the Colossus telescope would have been nearly eight times the diameter of Hawaii’s Keck Observatory, currently one of the largest ground-based observatories in the world. And since a telescope’s light-gathering power increases by the square of its diameter, the Colossus telescope would have also had a whopping 60 times the resolution...

Creating contagious STEM interest: The Adler Planetarium's Celestial Ball

Posted 11 months ago by Alison Klesman

Fundraising galas are a great opportunity to pull out your best formalwear, meet amazing people, and support a fantastic cause — like inspiring future scientists, engineers, and mathematicians. That’s exactly what took place this past weekend at Chicago’s Adler Planetarium, the oldest planetarium in the Western Hemisphere and, to me, the very model of modern and engaging public science programming. I grew up in a south suburb of Chicago and went there often when I was younge...

Guest blog: The BLAsT Class and Earth's Space Weather Forecast

Posted 11 months ago by Nicole Kiefert

By Abby Stephens and Keegan Engelking What is the first thing you think of when someone says space weather? Is it raining storms with zero gravity with rain drops going every direction? Or is it flashing interstellar clouds with space lightning? Although it is neat to daydream about space weather being this way, the reality is very different from these depictions. Dr. Patricia Reiff, a professor from Rice University specializing in space plasma and magnetospheric physics, took us on a jour...

Guest Blog: The BLAsT Class Learns to "Move it Like Moana"

Posted 11 months ago by Nicole Kiefert

By David Collicott and Gaby Loredo Astronomy in Moana? That’s what we thought. But Dr. Stephanie Slater gave us a lesson on the movie’s traditional Polynesian water navigation and its relation to the stars. Through the stars rise and set times, their altitude, and their relation to the stars around them, the ancient navigators were able to tell their location with great accuracy and purposely move from tiny island to tiny island in the vast Pacific Ocean. Dr. Slater did an am...

A total eclipse in southern Illinois

Posted 11 months ago by Alison Klesman

Like many Americans lucky enough to live in or travel to the path of totality on August 21, I witnessed my very first total solar eclipse. For me, this historic event took place in southern Illinois, nearly 400 miles from Astronomy’s offices in Waukesha, Wisconsin. It was not only a moving experience, but an exciting and fun one as well. My journey began Sunday afternoon; I’d driven down to my father’s house in a south suburb of Chicago the day before. Just before we left, t...

Amazing interest in the eclipse continues

Posted one year ago by Michael Bakich

St. Joseph, Missouri, is generating lots of buzz related to Monday’s upcoming total solar eclipse, and everyone seems to have been aware of it for some time. My wife and I started chatting with Donna Wilson, an area nurse, about the great event while waiting in line to order breakfast at Brioche, a local French restaurant. When we did order, we discovered that Donna who was part of a group of businesswomen, had paid for our meal (which was delicious, by the way). “This is a way to sa...
