Last month our Astro Chat with contributor Dr. Jean Creighton began a short series on the impact NASA's Hubble Space Telescope has had on our understanding of the universe.

Previously, we talked about how the Hubble confirmed for us that the universe is expanding. This month, it's all about exoplanets. As Creighton points out, "the Hubble Space Telescope was not the first instrument that saw exoplanets. But it was one of the first that could photograph an exoplanet."

It’s always exciting when new scientific discoveries are announced. It’s even exciting to talk about scientific discoveries that aren't yet confirmed. Such is the case for the potential ninth planet that astronomers have been theorizing about based on observations of the solar system.

Jean Creighton, Lake Effect astronomy contributor and director of the Manfred Olson Planetarium at UW-Milwaukee, joins Bonnie North every month to discuss the many different topics the universe and space exploration has to offer.

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

After a long winter of what felt like Wisconsin’s own “Polar Vortex,” it’s time to escape from under our roofs and enjoy the longest day of the year.
