Astrophiz 38: Richard Stephenson ‘Talking with Spacecraft’ & Dr Ian Musgrave’s ‘What’s Up Doc’

Astrophiz38b

Our feature interview is with Richard Stephenson, who is the Operations Supervisor at the Canberra Deep Space Communication Complex at Tidbinbilla in Australia.

The CDSCC is part of the Deep Space Network of NASA‘s Jet Propulsion Laboratory (JPL), managed in Australia by the Commonwealth Scientific and Industrial Research Organisation (CSIRO). Thanks to Glen Nagle (Episode 17) for facilitating this interview

Richard explains the technologies he uses to have up to 100 spacecraft contacts each week, and how he and his counterparts in Goldstone/Mojave and Madrid work in shifts around the clock to maintain two-way communications with 27 missions, including Cassini, Juno, New Horizons and the distant Voyager probes.

In our regular astrophotography and observations segment, Dr Ian ‘Astroblog’ Musgrave tells us what to look for in the night sky and reports on continuing ideal viewing conditions for Saturn and Mercury. In ‘Ian’s Tangent’ he tells us about different types of occultation and how they can be used to tell us the position, size and shape of asteroids.

Astrophiz 37: Robert Arrowsmith ‘The 8 metre Dish’ + Dr Ian Musgrave ‘What’s Up Doc’

dish2e
In this episode we’re celebrating our first 12 months of Astrophiz, where we have published 37 episodes, and it looks like our diversity and social media policies are working well, for we’ve featured 15 male and 22 women astrophysicists, astronomers, NASA rocket scientists, particle physicists, mission scientists and instrument scientists from the UK, Spain, India, Norway, Japan, Russia, Romania, Germany, Canada, the US and Australia and had well over 9000 downloads to listeners in more than 50 countries. 
 
For our special anniversary episode, we are re-interviewing our very first guest, Robert Arrowsmith from Melbourne, Australia, who is now leading the construction of an 8 meter radio telescope for the Astronomical Society of Victoria. 
 
Rob is one of the leaders in the Radio-Astronomy arm of the ASV and in Episode #1 he described the work being done at the ASV Leon Mow Radio Observatory, which is located in a RF quiet zone site about 90 minutes north of Melbourne in SE Australia
 
In our regular astrophotography and observations segment, Dr Ian ‘Astroblog’ Musgrave tells us what to look for in the night sky and reports on ideal viewing conditions for Saturn and Mercury. In ‘Ian’s Tangent’ he tells us about a very rare discovery where a white dwarf and a brown dwarf are dancing in a very closely orbiting binary star system called a cataclysmic variable.
 
Next Episode: Richard Stephenson from the Canberra Deep Space Communication Complex explains the technologies he uses to talk with Spacecraft like Cassini and the Voyagers.

Dr Ian Musgrave in our regular feature, ‘What’s up Doc?’ tells us what to look for in the night sky this week using naked eye, binoculars or telescopes, and Jupiter is ruling our skies.
In the news:
Dr Brad Tucker and ANU astronomers launch a Citizen Science project and public search of the southern skies for the elusive ‘Planet Nine’ using data from the Skymapper telescope at Siding Springs in Australia. 
2.The largest magnetic fields ever found in the universe are caused by collisions between immense galaxy clusters, and these giant magnetic fields are millions of light years across and 100 times larger than the  Milky Way.
3. How to hunt for a black hole with a telescope the size of Earth. How do you photograph a black hole? Impossible you say? Inventive researchers have plans to do exactly that, and hope to grab the first images of an event horizon — the point of no return from the black hole at the centre of our Milky Way.
4. Using the Australian AAOmega+2dF Spectrograph and the Southern African Large Telescope astronomers have just discovered one of the most massive superclusters  in the universe hiding behind the Milky Way in the constellation of Vela. This is a massive group of several galaxy clusters, each one containing hundreds or thousands of galaxies. The researchers estimate that this Vela supercluster could contain somewhere between 1,000 and 10,000 trillion stars. Their calculations also show Vela is about 800 million light-years distant and zooming farther and farther away from us at a speed of about 40 million mph (18,000 kilometers per second).

Astrophiz30: Out now on iTunes and Soundcloud.
Dr Elizabeth Tasker Debunks the notion that ‘Earth 2.0’ has been found in the Trappist1 system + Dr Ian Musgrave’s “What’s Up Doc”
Our feature interview is with Dr Elizabeth Tasker who gives a reality check to the claims that ‘7 earth-like planets’ have been found around TRAPPIST-1, a small star about 40 light years away, and in her most recent paper, calls for a more accurate definition of our use of the term ‘habitability’.
Elizabeth is a British astrophysicist who works at JAXA, the Institute of Space and Astronomical Science, the Japan Aerospace Exploration Agency.

Our regular segment features Dr Ian Musgrave of ‘Astroblog’ fame, and he tells us what to look for in the night and morning skies over the next few weeks.

In the news:

1. The Explosive beginnings of a supernova spotted for the first time (via Amy Middleton reporting for cosmosmagazine) and she writes about a new paper in Nature Physics about the spectacular transformation of a star, assumed to have been a red supergiant, into a supernova, just three hours after it began.

2. The unexpected discovery of young stars in old star clusters may send scientists back to the drawing board and change our understanding of how stars evolve (via Monthly Notices of the Royal Astronomical Society: Letters, posted in physDOTorg/astronomy)

3. A White Dwarf star X9, is the closest star ever found orbiting a black hole, and it’s orbiting at an astonishing 12 million km/h. The stellar dance between these two objects is taking place inside a globular cluster 47 Tucanae, a group of about a million stars orbiting the galactic centre about 15,000 light years from Earth. (reported by Marcus Strom for the Sydney Morning Herald)
