Chris Hadfield: What I learned from going blind in space

There’s an astronaut saying: In space, “there is no problem so bad that you can’t make it worse.” So how do you deal with the complexity, the sheer pressure, of dealing with dangerous and scary situations? Retired colonel Chris Hadfield paints a vivid portrait of how to be prepared for the worst in space (and life) – and it starts with walking into a spider’s web. Watch for a special space-y performance.

Today’s stories…

First results from ExoMars Trace Gas Orbiter During its first year in orbit the ExoMars Trace Gas Orbiter has made some surprizing discoveries about the impact of the recent global Martian dust storm and an apparent lack of methane in the red planet’s atmosphere.

Dragon spacecraft destroyed in dramatic explosion The first crew Dragon two capsule which successfully flew to the International Space Station in March has been destroyed in a major explosion at the Cape Canaveral air force station in Florida.

Stratolaunch test flight Stratolaunch has successfully undertaken the first test flight of the company’s behemoth twin fuselage six engine jetliner designed to launch satellites into space.

May Skywatch We tour the night skies of May which play host to the annual Eta-Aquarids meteor shower generated by Halley’s Comet.

New model for Nova explosions Scientists will need to go back to the drawing board to come up with new ways in which powerful explosions – known as novae – can occur on the surfaces of white dwarf stars.

Explaining super-luminous novae Astronomers have discovered that shockwaves generated during nova explosions can dramatically amplify their power and brightness.

NASA’s InSight Detects First Likely ‘Quake’ on Mars NASA’s Mars InSight lander has measured and recorded for the first time ever a likely “marsquake.”

New physics needed to explain differences in the Hubble Constant New observations are showing that differences in how fast the universe is expanding now compared to how fast it was expanding billions of years ago are no statistical accident.

The Science Report Climate change is now threatening the world’s doomsday vault. The world’s second largest colony of emperor penguins almost wiped out. Extreme ocean winds and wave heights are increasing around the globe. A small bone behind the knee, which was once rare in humans is becoming more common. Palaeontologists have unearthed a new species of hadrosaur dinosaur in Mongolia. History revisionists spewing lies and cherry-picked half-truths for racist and political propaganda

SpaceTime Background SpaceTime is Australia’s most respected astronomy and space science news program. The show reports on the latest stories and discoveries making news in astronomy, astrophysics, cosmology, planetary science, galactic and stellar evolution, physics, spaceflight, and general science. SpaceTime features interviews with leading Australian scientists about their latest research. The show is broadcast coast to coast across the United States by the National Science Foundation on Science360 Radio and around the world on Tune in Radio. SpaceTime is available in Australia as a twice weekly podcast which averages around three million downloads annually. It’s hosted on line through Bitez.com on all major podcast platforms. SpaceTime began life in 1995 as ‘StarStuff’ on ABC NewsRadio. Stuart Gary created the show while he was NewsRadio’s Science Editor, evening presenter, and news anchor (a position he held for more than 17 years). Gary wrote, produced and hosted StarStuff, consistently achieving 9 percent of the Australian radio audience share - according to Neilsen ratings survey figures for the five major Australian metro markets (Sydney, Melbourne, Brisbane, Adelaide, & Perth). The StarStuff podcast was hosted by ABC Science on line achieving over 1.3 million downloads annually. Sadly, the popular program was axed in 2015 during ABC budget cuts. Rather than remain with the ABC, Gary resigned to continue producing the show independently and rebranding it as SpaceTime. The first episode of SpaceTime was broadcast on February 8th 2016 and the show has been in continuous production ever since. SpaceTime now reaches an audience almost three times greater that it achieved as StarStuff and continues to grow.

The First Galaxies: What We Know And What We Still Need To Learn

“As we look farther back in time, we find that younger galaxies formed stars at faster rates than galaxies do today. We can measure the star-formation rate, and find that at earlier and earlier times, it was more intense. But then we find it hits a peak when the Universe is about two billion years old. Go younger than that, and the rate goes down again.”

We’ve come incredibly far in our quest to learn how the Universe came to be the way it is today. We can see out in space for tens of billions of light years, to galaxies as they were when the Universe was only a few percent of its present age. We can see how galaxies evolve, merge and the stars inside change. And we can see to even before that, when no stars or galaxies existed at all. But how did we get from there to here? There are still plenty of gaps in the story. We’ve never seen the first stars or galaxies; we’ve never witnessed the start of cosmic reionization; we’ve never seen the star formation rate jump from zero to a real, finite number. Yet with James Webb and WFIRST on the horizon, these gaps in our knowledge may – if we’re lucky – all disappear.

Come get the story on what we know about the first galaxies, and what we hope and have left to still learn!
