The 365 Days of Astronomy

Hosted by Steve Nerlich.

Dear Cheap Astronomy: Light slows down when it goes through glass, but how come it speeds up again when it comes out? Where does it get the energy from to regain that speed?

Dear Cheap Astronomy: When a machine runs in an atmosphere – some of the energy put into it is lost in the form of sound waves. So would that same machine run more efficiently in a vacuum where that energy is not lost as sound waves?

“Space weather and its impact on our technology-dependent society”

Special Guest: Dr. Brett Carter ( @DrBrettCarter )
Space weather is commonly associated with solar eruptions that cause large geomagnetic disturbances and bright auroral displays after they impact the Earth. It has been the topic of significant research interest and importance in the last century, primarily because of its effects on various modern technological applications; including, and certainly not limited to, electricity grid operations and satellite communications. 
In recent decades, our scientific interest in space weather has accelerated, along with our development of advanced technologies, and our reliance on them. The most serious threat posed by space weather is its proven ability to cause long-term and costly interruptions in electrical power supply, upon which many other aspects of modern-day life are very heavily reliant; e.g. the provision of water and gas. As such, this threat has been a primary motivation for scientists to investigate and better understand the near-Earth space environment, and how we as a society can better protect ourselves against future severe space weather events. Up until recently, the infamous 1859 Carrington event – the most severe geomagnetic storm in modern history – has been considered the ‘worst-case scenario’. Unfortunately, our ability to fully understand the Carrington event is hampered by the lack of scientific observations at the time. In July 2012, a Carrington-scale solar eruption directly hit the STEREO-A spacecraft, which is located ahead of Earth in Earth’s orbit around the Sun. The eruption originated from a region on the solar surface that was directly facing Earth only 1 week prior. It is abundantly clear that this event would have had significant consequences had it hit Earth, but exactly how lucky were we that it missed? To answer this question, the economic and societal impacts of such an event will be discussed. A direct comparison with other natural disasters – for example, hurricanes, earthquakes and floods – shows that a severe space weather event like that in July 2012 is capable of being the single most expensive natural disaster in human history.

From October 8, 2007.

Last week we talked about Jupiter and we could sense right away it would be too much to handle. This week, we’ll talk about Jupiter’s moons – how many are there? What makes them so interesting? Is it true that the most likely place in the solar system to find life (other than Earth) is actually on one of Jupiter’s moons? Hang on tight. We’re going to cover a lot.

Paul Hill, Ralph Wilkins and Jenifer Millard host. Damien Phillips and John Wildridge produce.

The Discussion: Earthling slave John got married! The new fashion of requesting telescopes at weddings, a good time of year for solar astronomy, the scores are in for the results of Jeni’s master’s degree, Jeni gets a sciencey summer job and we make a joking (but no less genuine) appeal for astronomy equipment to review in future shows.

The News: Rounding up the space and astronomy news this month we have:

NASA inflated Bigelow Aerospace’s inflatable habitat on the ISS

Progress on NASA’s attempts to send humans beyond low Earth orbit

Analysis of ALMA data hints at planetary formation beginning earlier than thought

An update on the origins of the elusive Planet 9

The Jupiter-bound Juno spacecraft gets ready to orbit the gas giant

Arizona astronomers find 65 young galaxies – the oldest galaxy cluster yet discovered

Woobusters: Continuing our quest to debunk the myths and conspiracy theories that persist in every dark corner of the news and the internet. This month’s topic, picked at random from Paul’s Big Hat of Woo, is moon landing hoaxers – the mother of all space-related conspiracy theories!

Q&A: Listeners’ questions via email, Facebook & Twitter take us on a journey into the astronomy issues that have always plagued our understanding or stretched our credulity. This month we get a question about our own observing and imaging of the skies:

How do you think the name of Planet 9 will be chosen if it’s eventually discovered – is it too late to start a campaign for Planet McPlanetface? Gavin Mills from Canberra, Australia

Description: Astronomers have long wished to observe the formation of galaxy clusters to learn about the formation of structure in our universe. Recently a team discovered one of the most distant clusters of galaxies that they have dubbed a proto galaxy cluster. In this podcast, Dr. Arjun Dey discusses this proto galaxy cluster, how it was discovered and what it tells us about the history of the universe.

Hosted by Dr. Pamela Gay with special guest Meri Amber ( http://www.meriamber.com/ / @meriamber ), a "Geek-Pop" singer & songwriter from Australia. She delights us with "Baby Get Me A Tardis", "Not Gonna Be Me", "The Ninja Song" and "I XOX U". They talk about cats & showers in space and filk music. And cheese. The internet didn't smile on us a couple times during the show, but we carried on anyway!

The YouTube video of "I XOX U" is here: https://www.youtube.com/watch?v=k_LH5bKc3CA It makes more sense when you see the video… Really.

Space is a dark and empty place, but it doesn’t have to be lonely. The gas giants Jupiter and Saturn, and the Ice Giants Uranus and Neptune each travel with dozens of companions.

Earth has the Moon, of course. And it turns out that for more than 100 years, Earth has enjoyed the company of a faithful asteroid friend, too!
