The 365 Days of Astronomy

Dr. Al Grauer hosts. Dr. Albert D. Grauer ( @Nmcanopus ) is an observational asteroid hunting astronomer. Dr. Grauer retired from the University of Arkansas at Little Rock in 2006.

Today's 2 topics:

- Dr. Galen R. Gisler and his team calculated what would happen if a large impactor hit our oceans. https://www.youtube.com/watch?v=imZmoxex9hc However, if the impact happened in the middle of a large ocean it might not be as bad as you'd think.

- Dr. Andrea Isella of Rice Univ. used the ALMA radiotelescope imaged the protoplanetary disk around HD 163296. It's in the direction of the Milky Way's center and is 400 light years away. The dust has 2 lanes cleared out by a pair of Saturn-sized protoplanets.

Streamed live Sept 13th.

Host: Fraser Cain ( @fcain )
Special Guest:

Regular Guests:

Dr. Paul Matt Sutter ( http://www.pmsutter.com/ & @PaulMattSutter )

Dr. Morgan Rehnberg ( http://cosmicchatter.org/ & @MorganRehnberg )

Dr. Kimberly Cartier ( http://KimberlyCartier.org & @AstroKimCartier )

This week's guest interview is with Dr. Claudia Lagos ( https://clagos.com/ / @CDPLagos ). Claudia is the Research Assistant at the International Centre for Radio Astronomy Research ( @ICRAR ), in the University of Western Australia. Her expertise is in modeling of physical processes in galaxies, such as gas accretion onto galaxies, star formation, stellar feedback, gas accretion onto black holes, among other similar mechanisms. She also works with large multi-wavelength surveys of galaxies to study the connection between galaxies and their central super-massive black holes.

This week's stories:

- Goodbye Cassini!

- An intermediate mass black hole has been found! Maybe… (100,000 SM)

- New Horizons is awake. For a while… Headed to 2014 MU69.

In the southern constellation of The Chameleon is a star called T Chamaeleontis, or T Cha for short. It's a T Tauri type variable star, has 1.5 times our Sun's mass, is 350 light years away and is just a baby, at 7 to 10. . . million years old.

The star has an inner ring, with a large gap separating it from an outer ring. This type of disk is called a Transition Disk.

Part 1: The 1.7 and 3.9 earth Radii rule.

Part 2: OK, so tell us about some actual exoplanets now.

As of August 2016, the current count of confirmed exoplanets is up around 3,400 in 2,617 systems – with 590 of those systems confirmed to be multiplanet systems. And the latest thinking is that if you want to understand what exoplanets are made of you need to appreciate the physical limits of planet-hood, which are defined by the boundaries of 1.7 and 3.9 Earth radii.

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

The Discussion: Jeni’s back and the band is back together to discuss watching this year’s Perseid meteor shower and coverage of the Great American Eclipse

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

The shortlisted explorer and missions of opportunity being considered by NASA

Jellyfish galaxies feeding supermassive black holes

Goodbye to the Cassini Saturn explorer

‘The Other Section’: This month we keep Paul’s festering Hat of Woo out of sight and take a long look at the Voyager spacecraft on the 40th anniversary of this programme, which revealed the solar system unlike any other space mission.

Streamed live September 8th.

This week, we return to our starting point, where Astronomy Cast began: Pluto. 11 years on, we have a whole new appreciation for the dwarf planet Pluto. We've visited it, probed it and taken pictures. It's time for an update.

Dr. Al Grauer hosts. Dr. Albert D. Grauer ( @Nmcanopus ) is an observational asteroid hunting astronomer. Dr. Grauer retired from the University of Arkansas at Little Rock in 2006.

Today's 2 topics:

- The real impact danger to Earth comes from comets, not asteroids. A researcher at GSFC recommends we have spacecraft ready to intercept and deflect the dangerous impactor.

- Micrometeorites can be collected from a roof's gutter! Jon Larsen collected many from Paris, Oslo & Berlin. & Dr. Matthew Genge of ICL studied the 0.3mm diameter rocks for a scientific paper.

Avivah Yamani hosts.

In the Manikmaya, which is an expanded version of a small part of the Tantu Pagelaran (an old Javanese manuscript), there is a story about the creation of the Universe. There are many versions of it because traditions of the earliest of Javanese culture have mingled with those from India (e.g. Hindu) and the middle East (eg. Arabic).

On November 28, 1819 French astronomer Jean-Jacques Blanpain of Marseille discovered it and it was named Comet Blanpain after him. He saw it in the morning skies in the constellation Virgo.

The comet was recovered in January of 1820 after the Moon had moved on, but the comet was very, very faint. It was moving away from the Sun and getting ever fainter, and had moved into a region of nebulae and it was lost.
