Looks like a good week to get smart, and it's all free.
Astrobiologist Chris Impey leads things off on Monday at 7:30 p.m. in room N210 of Steward Observatory with a talk on the ethical considerations of astronomy's quest to find life on other planets.
Impey will be talking about his latest book: "Encountering Life in the Universe: Ethical Foundations and Social Implications of Astrobiology."
Some of the questions the book addresses, according to its promo on Amazon.com:
"Are we alone in the universe? Are the planets our playground to treat as we will, or do we have a responsibility to other creatures who may inhabit or use them? Do we have a right to dump trash in space or leave vehicles on Mars or the moon? How should we interact with other life forms?"
Details at the Steward Observatory website.
On Tuesday at 6 p.m., the UA's Science Cafe continues its “Science of the Senses” series from the School of Mind, Brain, and Behavior at Magpie's Gourmet Pizza, 605 N. 4th Ave.

On Wednesday, The UA College of Social and Behavioral Sciences kicks off a series of lectures on "Happiness" at 6:30 p.m. at the Fox Theatre, 17 W. Congress St.
