Brentwood Library: The Birth, Life, and Bizarre Death of Stars

Stars are distant suns. Like our sun, they are born in interstellar clouds of gas and dust, and live long and relatively uneventful lives. In death, sun-like stars swell up into “red giants,” and cast off their outer layers into space, revealing a “white dwarf” core, a million times denser than water. Rare, massive stars die even more spectacularly, exploding as super-novas, and leaving “neutron stars” or “black holes behind. We owe our existence to star life and star death!

City Star Party (GO for Tuesday)

Hover above the moon like an astronaut and get eye-to-eye with the planets. Find colourful stars, star clusters, bright nebulae and even another galaxy. Our monthly City Star Party is the place to catch universe from within the city limits at Bayview Village Park. If you don't have a telescope then you will find many astronomers who would love to share a view. If you are thinking of buying a telescope, viewing with other people's equipment is the best way to make a good choice. If you have a telescope or binoculars, please bring it!

UofT Planetarium: The Birth and Death of Stars

Showtimes: 7:00pm, 8:00pm, and 9:00pm The stars in the night sky seem unchanging and eternal, and have remained the same for the history of human civilization. However, over millions and billions of years, new stars are born, live out their long lives, and eventually die in a blaze of glory. In this show, we will be exploring the lives of stars by visiting stellar nurseries, supernova remnants and much more! If you have questions please contact planetarium@universe.utoronto.ca
