ESOcast 29 Jun 2018, 14:00 UTC Near Earth Objects (NEOs) are bodies in the Solar System with orbits that can bring them into close proximity with the Earth. Every day, many of these objects collide with our planet, but most are too small to have any noticeable effect. However, there are larger objects that lurk within our Solar System with the potential to impact the Earth, like the large Chelyabinsk meteor in 2013, or even larger -- like the devastating asteroid impact that wiped out the dinosaurs. With the fate of the world at stake, scientists and engineers are working hard to protect us from these collisions. In ESOcast 168 we hear from Olivier Hainaut, an ESO astronomer, who explains the origin and nature of NEOs. He will also explore the potential threat NEOs pose to life on Earth, how we study them with ESO telescopes like the VLT, and how scientists plan to shield the Earth from this extraterrestrial threat.
SpaceTime with Stuart Gary 29 Jun 2018, 08:06 UTC New data from an armada of spacecraft at Mars has confirmed that a massive dust storm on the red planet has gone global. Astronomers have captured a rare glitch in the usually regular clockwork like spin of a pulsar. Ever since Voyager 1 flew past Jupiter back in the 1970s scientists have wondered about the origin of Jupiter's lightning which seemed to be very different to lightning on Earth. Now new data from NASA’s Juno spacecraft has found that while Jovian lightning is in some ways analogous to Earth's lightning – the two types are two types are poles apart in other ways.
Hubblecast HD 27 Jun 2018, 17:00 UTC Astronomers have found that ‘Oumuamua, the first interstellar object discovered in the Solar System, is moving away from the Sun faster than expected. Using data from the NASA/ESA Hubble Space Telescope, in cooperation with ground-based telescopes, a team of researchers concluded that ‘Oumuamua is most likely outgassing — suggesting that this enigmatic interstellar nomad is a peculiar comet rather than an asteroid.

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.
