Stars within galaxies hardly ever collide at random, they are just too far apart compared to their sizes.  But galaxy collisions are occurring all over the universe!  A galaxy collision may take hundreds of millions of years to play out.  But the results can be spectacular - new stars forming, black holes merging, and quasars erupting.  And look out!  Our own Milky Way Galaxy may be on a collision course with the Andromeda Galaxy.  Fireworks ahead!

The University of Kentucky Department of Physics and Astronomy is pleased to welcome the public to our astronomical observatory. Part of our program of public outreach is a presentation on an interesting topic in astronomy followed by a visit to the observatory. The Kentucky SkyTalk is held on the second Thursday of every month.  A 45 minute program on astronomy will begin at 8:00 PM in Room 155 of the Chemistry-Physics Building. After the presentation, you are invited to view the sky through our 20-inch telescope, weather permitting.

Free parking is available on the top floor of parking structure #2, next to the observatory. With the exception of paid parking, without a valid parking permit, leaving your vehicle somewhere other than next to the observatory will result in a parking citation.

All are welcome and there is no charge. Tell your neighbors. Bring your kids.

Have you ever wondered how the solar system formed? Why are there rocky planets close to the sun while the giant planets reside farther away? What kinds of environments are suitable for the formation of our sun? In this talk we will investigate the current theories of solar system formation and evolution. We will also see different kinds of planetary systems around stars other than the sun and discuss abnormalities and their possible formation.

It’s considered rude to ask a person their age. But like someone sensitive on the subject, the universe has offered up many conflicting ages. History records that the answer to the title question depends strongly on when the question was asked. The discovery that stars age and die was a beginning of our modern understanding of cosmology, and gives us an insight into what the universe will look like in the future.

Our Sun is amazingly stable in its energy output and has been for several billion years. There are other stars which do not remain stable and actually pulsate with a well-defined period. I will discuss two types of pulsating stars, the Cepheid and RR Lyrae variables.  Brighter variables can be easily observed with small telescopes making them interesting objects for professional and amateur observers. Understanding of the pulsations allows astronomers to determine aspects of how stars evolve. As they beckon in the night, they allow accurate distance determinations of galaxies that are very far away.

Who needs humans on Mars when we already have bug-eyed rovers trundling along the Martian surface?  Amazingly, one of these rovers has been on duty for 10 years and is still going strong.  (What astronaut would want to hang out on Mars for that long?)  The Mars Exploration Rovers and the Mars Science Laboratory "Curiosity" have sent back thousands of pictures and other information about Mars.  Let's take a look at what they have seen and what they have learned about Mars present and past.

Thursday of the month, they are always free and open to the public.

The Gospel of Matthew records a peculiar astronomical event that occurred at the birth of Christ. Could the “Christmas Star” have been a nova, a supernova, a comet, or some other spectacular sight? I will talk about what was visible around the time of the birth of Christ, and describe Kepler's idea that that the Star was a planet alignment that guided the “wise men from the East.”
