The Titanium Physicist Podcast 19 Feb 2018, 05:05 UTC A supermassive blackhole at the centre of a galaxy can cause the gas that falls into it to glow SO BRIGHT that it stops the creation of new stars. What? How?
The Star Spot 18 Feb 2018, 23:40 UTC It’s our cosmic backyard, and yet our own solar system is still full of surprises. Now it turns out we were “totally wrong” when it comes to just about everything we thought we knew about Jupiter. That’s not me speaking, it’s Scott Bolton, principal investigator for the NASA Juno mission to Jupiter. From its magnetic field and atmosphere down to its very core, Jupiter is being rediscovered and transformed. Today we’re joined here at The Star Spot by Dr. Bolton to discuss the rewriting of our textbook on the solar system’s biggest world.
StarDate Online 18 Feb 2018, 06:00 UTC Here’s a phrase that you probably haven’t heard before: solar antapex. It’s the location in the sky that’s opposite the direction that Sun and Earth are moving through the galaxy. It’s marked by the constellation Columba, the dove, which scoots quite low across the south on February nights.
StarDate Online 17 Feb 2018, 06:00 UTC The smallest of the solar system’s major planets is hiding in the Sun’s glare right now. That’s because Mercury is at superior conjunction — it lines up behind the Sun as seen from Earth. As it moves away from the Sun, it’ll climb into decent view in the early evening sky in a couple of weeks.
NASACast Audio 16 Feb 2018, 13:30 UTC We’re doing something a little bit different in Episode 32 for African American History Month. We team up with our African American Employee Resource Group at the Johnson Space Center to bring 4 guests from different areas of expertise like life support systems, robotics, flight control and leadership to explain what they do and the paths they took to work at NASA. This episode was recorded on January 31, 2018.
StarTalk Radio 15 Feb 2018, 23:01 UTC Slide down the ice with Gary O’Reilly and Chuck Nice as they investigate the surprising science of curling. Featuring author and curler Dean Gemmell, physicist John Eric Goff, 2018 Olympic curler Nina Roth, and 2006 gold medalist Brad Gushue. (Warning: Adult Language.)
Hubblecast HD 14 Feb 2018, 15:00 UTC Our eyes detect only visible light, but on board Hubble are a variety of instruments that together detect many different wavelengths of light. This means that Hubble is able to observe galaxies over a wide range of wavelengths to reveal features that would otherwise remain invisible to our eyes.

12: New galaxy survey measuring the expanding universe - SpaceTime with Stuart Gary Series 21 Episode 1214 Feb 2018, 07:00 UTC New galaxy survey measuring the expanding universe. Falcon Heavy blasts into history on a car trek beyond Mars. One of the Milky Way’s first stars discovered. Earth survives two near misses.
StarDate Online 13 Feb 2018, 06:00 UTC Our home galaxy, the Milky Way, is on the move. It’s being pulled by the gravity of other galaxies, which are tugging in several directions.
StarDate Online 12 Feb 2018, 06:00 UTC Not many people seek out dark skies on cold winter nights — they’re not prime skywatching time for much of anyone. But those who do find dark skies get a treat: a nice display of the Milky Way. It arcs high overhead in early to mid evening right now. It’s anchored in the southeast by Sirius, the night sky’s brightest star. It then climbs high overhead to the “horns” of Taurus, then drops toward M-shaped Cassiopeia in the north, and the tail of Cygnus, the swan, in the northwest.
