Neil deGrasse Tyson is the heir apparent to Carl Sagan, so it's only fitting that the astrophysicist and director of the Hayden Planetarium is starring in a reboot of Sagan's "Cosmos" series about the universe and everything in it. The new "Cosmos: A Spacetime Odyssey" premieres this Sunday at 9pm ET on FOX and Monday 10pm ET on National Geographic. The New York Times reported that the new "Cosmos" will be shown in 170 countries and 45 languages making it the largest global opening ever for a television series.

Tonight, ahead of the "Cosmos" premiere date, Neil deGrasse Tyson along with the creators of the new 13-part part series will take part livestream Q&A online. For tonight's Q&A, Tyson will be joined by Ann Druyan, Sagan's widow and collaborator on the original "Cosmos" series, who is an executive producer, writer and director on the new series, as well as executive producer Seth MacFarlane of "Family Guy", executive producer Mitchell Cannold, executive producer and director Brannon Braga and co-executive producer Jason Clark. The live interactive Q&A will begin at 9pm ET and fans can submit questions via Twitter using #cosmoslive.

Carl Sagan's original "Cosmos" series aired on PBS in 1980 and remains the most widely watched PBS series in the world. The original 13-part series won an Emmy and a Peabody Award and has been broadcast in more than 60 countries and seen by over 500 million people. In 2012 the Library of Congress selected the book version of the show as one of the 88 books that shaped America.

The new "Cosmos" with Neil deGrasse Tyson as host offers a much need revamp of the series, as much as happened since Sagan took us on a tour of time, space and the origin of life. For instance, the Mars rover is beaming us images from the red planet, Pluto is no longer a planet, and Google Sky and Google Moon allows us to view celestial bodies on our smartphones. NASA's space shuttle program may be retired, but billionaire Richard Branson has launched Virgin Galactic for impending commercial spaceflights and others are preparing a human settlement on Mars, which shows our interest in space has not abated.
