StarTalk Radio 22 Jun 2018, 22:00 UTC Science really is everywhere. From the Big Bang to quantum mechanics to free will, we explore it all featuring Neil deGrasse Tyson, comic co-host Chuck Nice, physicist Brian Greene, neuroscientist Heather Berlin, and rapper Baba Brinkman. Recorded live at the Brooklyn Academy of Music.
NASACast: Space Shuttle and Space Station Video 22 Jun 2018, 14:52 UTC THE NANORACKS REMOVE DEBRIS SATELLITE WAS DEPLOYED FROM THE SPACE STATION’S ROBOTIC ARM THIS WEEK. REMOVE DEBRIS WILL LOOK TO MANAGE SPACE JUNK BY LITERALLY PULLING IT DOWN OUT OF ORBIT TO BURN UP IN THE ATMOSPHERE. RESEARCH HAS SHOWN THAT REMOVING THE LARGEST DEBRIS SIGNIFICANTLY REDUCES THE CHANCE OF COLLISIONS, SO REMOVE DEBRIS WILL USE A 3D CAMERA TO MAP THE LOCATION AND SPEED OF DEBRIS, THEN CAPTURE AND DE-ORBIT SIMULATED DEBRIS, CUBESATS IN THIS TEST, UP TO ONE METER IN SIZE. THE EXPERIMENT WILL TEST NET CAPTURE, HARPOON CAPTURE, VISION-BASED NAVIGATION, AND DRAGSAIL DE-ORBIT TECHNIQUES FOR REMOVING SPACE JUNK. EXPERTS HERE ON EARTH CAN ANALYZE VIDEO FROM THESE RUNS TO SEE WHAT WORKED AND FIND THE BEST WAYS TO CLEAN UP THE SPACE AROUND US.
SpaceTime with Stuart Gary 22 Jun 2018, 06:16 UTC Mystery objects discovered near supermassive black hole. Astronomers have discovered several bizarre objects at the galactic centre that are concealing their true identity behind a smokescreen of dust; they look like gas clouds but behave like stars. Life rebounded within a few years after the dinosaur-killing asteroid hit. A new study claims life quickly returned to the dinosaur-killing KT boundary event asteroid impact site. New Kepler mission. NASA former planet-hunting Kepler space telescope is on a new mission studying the secrets of open star clusters.
Hubblecast HD 21 Jun 2018, 18:00 UTC An international team of astronomers using Hubble has made the most precise test of general relativity yet outside our Milky Way. A nearby galaxy acts as a strong gravitational lens, distorting light from a distant galaxy behind it to create an Einstein ring around its centre. By comparing the mass of the lensing galaxy with the curvature of space around it, the astronomers found that gravity on these astronomical length-scales behaves as predicted by general relativity.
ESOcast 19 Jun 2018, 11:00 UTC Each year, several outstanding early-career scientists have the opportunity to further develop their independent research programmes at the European Southern Observatory. Fellowships are available both at ESO’s Headquarters in Garching near Munich, Germany, and at ESO’s astronomy centre in Santiago, Chile.
SpaceTime with Stuart Gary 14 Jun 2018, 03:07 UTC Dark matter, one of the biggest questions in astronomy and physics may just have been solved in what could be the most important discovery since the accelerating expansion of the universe, finding the Higgs Boson and the detection of gravitational waves. Scientists may just have discovered a potential fourth type of neutrino, which could be the hypothetical sterile neutrino particle, considered by many as the particle responsible for Dark Matter.
ESOcast 13 Jun 2018, 14:00 UTC ALMA has uncovered convincing evidence that three young planets are in orbit around the infant star HD 163296. Using a new planet-finding technique, astronomers have identified three discrete disturbances in the young star’s gas-filled disc: the strongest evidence yet that newly formed planets are in orbit there. These are considered the first planets discovered with ALMA.
SpaceTime with Stuart Gary 8 Jun 2018, 10:54 UTC Scientists have confirmed the existence of methane dunes on Pluto’s vast Sputnik Planitia ice plain. An asteroid first detected on Saturday near the orbit of the Moon has exploded just a day later in a spectacular airburst over southern Africa. Virgin Galactic has carried out a second powered test flight of its VSS Unity space plane in the skies above California’s Mojave desert.
