Put your idle 3D printer to work!   You can now 3D print the structure of a supernova of a binary star system.

A new way to experience the universe.   One possibility, it could be a standard presentation for clouded out observing session at a science faire.

The Department of Physics at The University of Texas at Austin is excited to host a free public science talk featuring 2017 Nobel Laureate Kip Thorne. Dr. Thorne will reminisce about the discovery of gravitational waves by LIGO and the fifty-year effort that led to this discovery. He will describe the way LIGO’s observations, together with numerical simulations, are transforming our understanding of black holes, and his vision for the future of gravitational wave astronomy.

Astronomy on Tap ATX is held on the third Tuesday of every month at The North Door (502 Brushy St., Austin, TX) at 7.30pm (doors open at 7pm)
Paid Parking is under IH-35.   Fill a car and have an interesting evening of astro discussions.


April 17 2018 meeting:
Prof. Chris Sneden will talk about RR Lyrae stars,
Dr. Judit Ries will take us to explore the nature of the mysterious interstellar cigar and other flying objects;
Dr. Brandon Bozek will discuss the nature of dark matter from his simulation of Milky Way and our neighboring galaxies.

YouTube Channel is available for previous presentations

Club member Dr. Ed Wiley will give us an introduction and overview of the activities and opportunities for amateur astronomers participating in the AAVSO (American Association of Variable Star Observers). The AAVSO gives everyday amateur astronomers the opportunity to participate in and contribute to scientific research. Dr. Wiley has been active in the AAVSO for a number of years and currently instructs an AAVSO course covering CCD Photometry.

Club member Stephen Hill will discuss his continuing project to run guiding and imaging tools on a Raspberry PI low cost, single board computer. He will concentrate his discussion on getting a auto-guider solution running on the RasPi.

Multiple members will give short talks about their choice of topic. They may show and discuss smaller new projects they have worked on, new equipment, new books, or observing session results in the form of field reports or astro-photography they have done.

Bob's interesting presentation got me thinking about another way to predict local weather conditions.
I wonder if the Weather Underground API could be used to build an application in javascript that could be used to do short term predictions.
I'm thinking if one could automate checking of personal weather stations in a small grid around a location, one could determine humidity gradients in time and space.
As Jeff brought up, one would need to first select those weather stations which show believable conditions, as some do seem out of calibration.
The "developer" key at Weather Underground permits 500 accesses per day is free. Max is 10 per minute.

Club Member Bob Read will discuss his latest project: a compact wireless weather station packaged into a cube less than 1 inch on each side. Such a device can be used as a home weather system or used to report conditions for a remote observatory.

From the article:
  • Metalenses have a wide range of applications. The most obvious is imaging. Flat lenses will make imaging systems thinner and simpler. But crucially, since metalenses can be fabricated in the same process as the electronic components for sensing light, they will be cheaper.

It might evolve/mature to be higher quality at lower costs.  Something to watch boom or bust.

A short video retrospective of the Hubble Space Telescope will be shown. This will be followed by multiple club members showing off their favorite HST image explaining why it's their favorite and then describing a little background about the main subject of the image.
