66: Ultra-bright early galaxies may be less common than we think - SpaceTime with Stuart Gary Series 21 Episode 6622 Aug 2018, 10:15 UTC Ultra-bright early galaxies may be less common than we think: Astronomers have discovered that one of the brightest galaxies in the distant universe isn’t so far away after all. The findings have profound implications for models of how galaxies formed when the universe was in its infancy.
The Star Spot 20 Aug 2018, 01:00 UTC The recent discovery of a lake of liquid water beneath the Martian south pole culminates a series of stunning discoveries that are forcing us to rethink the question of habitability on the Red Planet. Now two space missions are underway aimed at sites on Mars that may be the best candidates yet for life and boasting the most advanced bio detection instruments ever sent into space. To help us prepare, today we’re joined at The Star Spot by space physicist David Hamilton.
SpaceTime with Stuart Gary 16 Aug 2018, 11:01 UTC Parker Solar Probe launches on a mission to touch the Sun: NASA’s Parker Solar Probe has successfully blasted into space on a historic mission to explore the Sun’s Corona. A mysterious monster from the early universe: Astronomers have discovered a massive, inactive galaxy located more than 12.15 billion light-years away.
NASACast 10 Aug 2018, 03:10 UTC A TOOL THAT HELPED GUIDE SAILORS ACROSS VAST OCEANS FOR CENTURIES IS NOW BEING PUT TO THE TEST IN SPACE. THE CREW HAS BEEN TESTING OUT A SEXTANT, A DEVICE WITH A SMALL TELESCOPE-LIKE SIGHT THAT CAN TAKE PRECISE MEASUREMENTS BETWEEN PAIRS OF STARS. THESE WERE ACTUALLY USED IN THE EARLY DAYS OF HUMAN SPACEFLIGHT ON PROGRAMS LIKE GEMINI AND APOLLO, AND MISSION PLANNERS ARE ONCE AGAIN LOOKING AT HOW THEY COULD BE USED FOR EMERGENCY NAVIGATION NEEDS ON DEEP-SPACE EXPLORATION VEHICLES LIKE ORION.
StarDate Online 9 Aug 2018, 05:00 UTC The south pole isn’t a very pleasant place to live, especially during the winter. It’s dark for six months, and temperatures average about 70 below zero. Yet those conditions make it a great place for astronomy. And scientists are taking advantage of those conditions now, during the last couple of months of southern winter.
SpaceTime with Stuart Gary 1 Aug 2018, 11:27 UTC Liquid water discovered under the Martian south pole: A huge subsurface liquid water lake has been detected near the Martian south pole. Mars Opportunity Rover could be in trouble: There are growing concerns about the safety of NASA's Mars Opportunity rover. Finding the foundations for massive stars: A new study has found that the collapse of molecular gas and dust clouds to create new stars occurs far more quickly than previously thought.
