On Monday, part of the United States will experience a total solar eclipse, where the moon completely covers the sun. Milwaukee won’t get totality, but we will still experience a partial eclipse. 

"In Milwaukee we're going to see a partial solar eclipse, 86%... most people, if they've seen a solar eclipse at all, it's likely to be partial," says Jean Creighton, Lake Effect astronomy contributor and director of the Manfred Olson Planetarium. 

On August 21st, parts of the United States will experience a total solar eclipse. It’s the first time in a century that the path of totality will be visible from the west coast to the east. Milwaukee isn’t in the totality path but it will still be darker than normal as the sun will be 86% eclipsed.

This summer, the northern hemisphere sees some pretty spectacular astronomical events. The Perseid meteor showers will peak in mid August and about a week after that, parts of the United States will witness the first total solar eclipse since 1979. It’s also the first one visible from the Pacific ocean to the Atlantic since 1918.

The question cinema has tried to answer time and time again, with the most recent attempt by the movie Arrival, may finally have an answer as astronomer Jean Creighton provides promising new hope for whether life can exist beyond earth. “There could be life right now in the solar system unbeknownst to us,” says Creighton.

Every month, contributor Jean Creighton joins Lake Effect to talk about things astronomical. This month, the topic was prompted by two people asking her the same question within twelve hours.

"People are intrigued by black holes," Creighton says. "They want to know what they are, how they work - but on the other hand they (don't want the myth broken)."

Creighton explains the science of black holes and breaks some common myths, as well as the black hole bubble we may be living in:

For centuries, the constellations have provided a roadmap of the night sky, helping sailors and other voyagers navigate, well before the existence of GPS technology.  Even today, astronomers use constellations to describe the location of stars, comets and other heavenly bodies.

It’s been almost 30 years since scientists first discovered their first exoplanet - a planet orbiting a star other than our own sun. But the scientific community is especially excited now with the discovery late last month of the most earth-like exoplanets yet.

If you had an astronomer next to you, what would you ask them? When astronomy contributor Jean Creighton isn't in the Lake Effect studio, she is very much still in the public eye, leading the Manfred Olson Planetarium at UW-Milwaukee. And part of her job is to do research among the public to find out what people are naturally curious about.

Upon occasion Creighton will approach people not as the leader of a planetarium, but as another civilian interested in space, and ask them what they are interested in. Surprisingly, most people want to know about distance.

Many are familiar with the concept of citizen science: opportunities for amateurs to play a role in helping researchers gather or process scientific data. That could involve a backyard bird count, or the use of a home computer to sift through terrabytes of data.

As 2016 draws to a close, Manfred Olson Planetarium at UW-Milwaukee director and Lake Effect contributor Jean Creighton highlights the important astronomy stories of the past year:

Highlights of 2016:

1. Discovery of Gravitational Waves

Every few years, it seems we’re treated to photography from outer space that gives us a brand-new perspective on the universe. Missions like the Mars Pathfinder, with its Sojourner rover, have allowed people to see places humans will probably not experience in the near future – though they might, someday.

On this day in 1964, the Spacecraft Mariner 4 was launched into its 228 day mission that would bring the spacecraft within about 6,000 miles of Mars. That mission resulted in the first close-up photos of the Red Planet.

In celebration of that historic mission, November 28th is known as Red Planet Day.

"At first, all we wanted to do was learn more about the environment, but now, of course we want to get [to Mars]. We want to send a person there," says astronomy contributor and director of the Manfred Olson Planetarium at UW-Milwaukee, Jean Creighton.
