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:

- On Jun 29, 2015, Pluto occulted a star, UCAC4 347-165728 showing us that it had an atmosphere. Now high school students can join in the hunt for TNO occultations.

- The Earth-approaching asteroid 3200 Phaethon and its debris trail gives us the Geminid meteor shower each December. 2016 LV47 was discovered by Eric Christensen of the Catalina Sky Survey, but it's a 1,000' diameter solid body instead of a rubble pile like Phaethon.

Title: Using dusty plasmas to study all four states of matter.
Abstract: Plasmas (or ionized gases) are often referred to as a “fourth” state of matter – but perhaps, they should be the “first”.  This is because the plasmas are the most common state (over 95%) of matter in the visible universe.  From technologies such as fluorescent lighting and microelectronics manufacturing to natural systems such as lightning, the aurora, and the solar wind, plasmas are ubiquitous in our lives. Even more remarkably, over the last three decades plasma scientists have learned how to control a certain type of plasma – a “complex” or “dusty” plasma – to make it have solid-like, fluid-like, or gas-like properties.  This means that dusty plasmas are not just a fourth state of matter – they can take on the properties of all four states of matter.  This presentation will provide an introduction to the physics and applications of plasmas and will describe some of the fascinating aspects of complex/dusty plasma research – including the one-of-a-kind, high magnetic field dusty plasma laboratory that has recently begun operating at Auburn.
Presenter: Dr. Ed Thomas, Jr.  Auburn University

We get questions every week about string theory and topics popularized by science fiction. Here’s the problem. There’s just no evidence. Each of these is based on wonderful and well-formed mathematical equations, or wishful thinking, but they’re very hard (if not impossible) to test in the real Universe.

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. Michaël Gillon and his team examined nearby red dwarf stars for exoplanets. They found 3 planets circling a 39 light-year away star now called Trappist 1.

- The Geminid meteor shower in December is left over from 3200 Phaethon, an asteroid discovered in 1983. This asteroid may in its own turn be an ejected chunk of asteroid 2 Pallas, the second asteroid that was found, having been discovered in 1802. Phaethon appears to eject the meteorites each time it makes close passes to the Sun in its 523.5 day orbit.

This podcast was recorded in a noisy exhibit hall at the 2017 AAS meeting in Grapevine, Texas. We apologize for the poor audio quality.

Description: The Gemini Observatory is an international collaboration that runs 8 meter telescopes on Mauna Kea in Hawaii and Cerro Pachon in Chile. In this podcast recorded at the American Astronomical Society meeting in Grapevine, Texas, Dr. Andy Adamson, Dr. Morten Andersen, and Dr. Andre-Nicolas Chene discuss various aspects of the observatory and research carried out by Gemini.

Most scientists believe that about 13.82 billion years ago the Universe exploded into existence in what we call the Big Bang. Since then, it has evolved into the place we see today — and it’s still growing!

No matter which direction we look in space, distant galaxies appear to be moving away from us. The farther away a galaxy is, the faster it’s moving away. This is called the ‘expansion of the Universe’.
