Walkabout the Galaxy
"Out There," aliens, dark star
Astrophysics and Astronomy | Physics
We almost called this "Everything you wanted to know about alien sex with Dr. Michael Wall", but it's not alien sex with Mike Wall, it's Mike Wall telling us about alien sex! A senior writer with Space.com and author of the new book Out There, Mike joins the astroquarks to talk about aliens, paranormal beliefs, and an exotic type of star called a dark star. Plus space news, trivia, and it turns out the astroquarks are really interested in three-way alien sex.
Stars Being Born
When a star is born, nuclear fusion begins in the center of a massive ball of mostly Hydrogen gas, converting tiny amounts of mass to ginormous amounts of energy in one of the universe's neatest tricks. While A Star is Born in the movies every 20 to 30 years, in the Milky Way a star is born every couple of months, but without the Hollywood fanfare, and rarely any Oscar buzz. But don't wait around forever to see a star being born: the Milky Way has already converted 90 percent of its initial allotment of gas to stars, so this show won't go on forever. "Stars Being Born" now playing for its 13 billionth straight year!
