20: Astronomers detect ancient signals from the first stars in universe - SpaceTime with Stuart Gary S21E2016 Mar 2018, 06:27 UTC Astronomers have for the first time ever detected an ancient signal from the first stars in the universe. The discovery places the first stars at just 180 million years after the big bang – far earlier than previously thought.
StarDate Online 15 Mar 2018, 05:00 UTC Scientists pretty much agree that our universe — everything that we can see and touch — evolved from a single moment of creation, known as the Big Bang. It happened 13.8 billion years ago, and it created not just matter and energy, but space and time as well. But there’s absolutely no agreement about what came before the Big Bang. Some say that there was nothing at all. It’s an idea supported by Stephen Hawking, who has said that the universe wasn’t created, it just is.
StarTalk Radio 14 Mar 2018, 19:10 UTC Join Neil deGrasse Tyson as he sits down with world-renowned physicist Stephen Hawking. We offer this episode in memory of Dr. Hawking's passing, and in celebration of his life. With co-host Matt Kirshen, astrophysicist Janna Levin, theoretical physicist Michio Kaku, and Bill Nye the Science Guy.
NASACast 13 Mar 2018, 13:07 UTC NASA EDGE talks with Dr. Jamese Sims about how scientists at the National Oceanic and Atmospheric Administration (NOAA) are evaluating data and developing specific products to serve the meteorological community. GOES-S, (GOES 17 when operational with GOES 16) will provide the most comprehensive look at weather data from the West Coast of Africa to New Zealand, and as a result, more and more applications of weather data can now be generated.
StarDate Online 13 Mar 2018, 05:00 UTC Leo, the lion, springs across the sky on March nights. He’s in the east at nightfall, marked by his prominent “heart,” the bright star Regulus, which is a third of the way up the sky. If you scan the sky below and to the left of Leo with a telescope, you’ll see clusters of galaxies. They contain thousands of galaxies in all. Each galaxy is an “island universe” similar to the Milky Way — a vast assemblage of millions or billions of stars.
StarDate Online 12 Mar 2018, 05:00 UTC The proper names of the three brightest stars of Leo, the lion, all sound like destinations from a spy thriller: Regulus, Denebola, and Algieba. And the fourth-brightest star sounds pretty exotic, too: Zosma. It’s from a Greek words that means “girdle,” because the star marks the lion’s hip. Unfortunately, though, the star itself isn’t all that exotic. It’s in the prime of life, so it’s fusing the hydrogen in its core to make helium. It’s the same phase of life the Sun is in, known as the main sequence.
