Jean Creighton

Astronomy Contributor

To Dr. Jean Creighton, physics is the gateway to astronomy. She studied physics at the University of Athens and went on to earn a masters degree from Saint Mary's University in Halifax, Nova Scotia, and a PhD in Astrophysics from the University of Waterloo. She began teaching astronomy at UW-Milwaukee in 1999 and in 2007, she took over as director of UWM's Manfred Olson Planetarium.

Pluto was in the headlines a few years ago when it was demoted from official planetary status to what many now refer to as a dwarf planet.  Some still haven’t accepted that demotion.

But regardless of where you come down on the debate, the recent pictures sent back from Pluto were breathtaking.  It’s the furthest place humans have ever sent a mission with such a close pass-by. Our astronomy contributor Jean Creighton explains more about the planet and what’s next for our understanding of it:

If you hear the phrase “solve for x,” and break into hives, don't fear. Jean Creighton joins Lake Effect every month to talk astronomy, but nearly everything she does is based on mathematics.

"Math can resemble in some ways another language, but we can master it to some extent. At least enough to communicate what we need," Creighton says.

She further explains how math and astronomy are interconnected:

From how we drive our cars to how we watch TV and read the newspaper, the digital revolution has affected much in our lives. The changes have been especially profound for scientific research.

Every month, Lake Effect's Bonnie North chats with the director of UWM’s Manfred Olson Planetarium, Jean Creighton. From viewing constellations to what it takes to land on a comet to exoplanets, they've talked about a wide range of astronomical topics.

Rather than taking place in the studio, this month's AstroChat segment was recorded at the planetarium in front of an audience of WUWM listeners.

Creighton shared her experience of traveling to the Stratosphere, spending 20 hours there to observe young and middle aged stars with an infrared telescope.

Every month, we travel the stars with our astronomy contributor Jean Creighton. Creighton is the director of the Manfred Olson Planetarium on the campus of UW-Milwaukee.

We’ve talked about everything from visible constellations to exoplanets to landing a probe on a comet. Now that it's summer, we are talking about light - star light, infrared light.

For the last few months, Lake Effect's astronomy contributor has talked about how the things in the night sky came to be. As the weather warms up, it's time to tell a simpler story.

It’s the time of year that it’s really pretty comfortable to just go out and look up into the night sky.

Lately, Lake Effect has been talking with astronomy contributor Jean Creighton about how things form in the universe – things such as stars.

This month, the focus is a little closer to home, or maybe a lot closer to home. How do planets, like our own, come to be? Lake Effect astronomy contributor Jean Creighton is the director of the Manfred Olson Planetarium, and she explains that stars come before planets:

Last week was a great one for fans of the aurora borealis.  The Northern Lights were visible far further south than normal, thanks to increased solar activity. Ambient light made seeing them basically impossible in metro Milwaukee, but out in the country, there were lots of sightings.

So what’s responsible for the shimmering, colorful atmospheric magic?  Astronomy contributor and director of the Manfred Olson Planetarium at UW-Milwaukee, Jean Creighton, explained to Bonnie North exactly how they work - starting with two basic ingredients: the sun and the earth's atmosphere.

From landing a probe on a comet to even more discoveries on Mars, it’s been quite a year for astrophysics and cosmology.

It was big news last week when the European Space Agency landed a probe on a comet.

There was much excitement in India yesterday when that country’s first effort to send an orbiter to Mars succeeded.

Astronomy contributor Jean Creighton joined us to talk about what stars and constellations are visible to us in the night sky this month. 

"It’s going too fast and the isotope ratios are different; this one came from elsewhere," says Creighton. "That means that you can look up at a really bright star. Arcturus is really bright, and pretty, and you’re looking at a piece of another galaxy."

When the whole universe is out there to explore, how do astronomers decide what questions they want to ask?
