The History of the Hubble Space Telescope

Posted by

As part of our celebrations leading up to the 25th anniversary of the Hubble Space Telescope, we are holding out first #Hubble25 event.  We’ve invited a panel to take a look back and discuss the legendary and illustrious history of a telescope that has changed our views of the universe forever and inspired a new generation to look up.

Please join +Tony Darnell Dr +Carol Christian  and +Scott Lewis as we take a glimpse into Hubble’s past with Ken Carpenter, Russ Werneth and +Carolyn Collins Petersen.

On October 19, 2014 the +Hubble Space Telescope gathered observations of the close flyby of Comet Siding Spring with Mars.

Please join +Tony Darnell Dr +Carol Christian  and +Scott Lewis as they discuss these observations with +Max Mutchler , +Zolt Levay Casey Lisse and Jian Yang Li.

The Exciting Possibilities of 3D Printing in Zero-G

Posted by

+NASA is currently engaged in exploring 3D printing in space using a printer designed by Made In Space.  This printer is designed to work in a microgravity environment to produce space assets in… well… SPACE!

NASA wants to test the idea of making parts inexpensively in orbit as opposed to down here on Earth and launching them to where they need to be.

3D printing serves as a fast and inexpensive way to manufacture parts on-site and on-demand, reducing the need for costly spares on the International Space Station and future spacecraft. Long-term missions would benefit greatly from having onboard manufacturing capabilities. Data and experience gathered in this demonstration will improve future 3-dimensional manufacturing technology and equipment for the space program, allowing a greater degree of autonomy and flexibility for astronauts.

Please join +Tony Darnell Dr +Carol Christian  and +Scott Lewis as they discuss this new experiment from NASA with +Jason Dunn and Michael Snyder from Made in Space, the company contracted by NASA to build the 3D printer currently being used.

The Scientific and Cultural Impact of Hubble; Meet ATLAST, a Next Generation Space Telescope

Posted by

SPECIAL TIME: 4pm EDT, 8pm GMT!

In the 24 years Hubble has been exploring the universe, we have gone through four U.S. Presidents, and 5 U.K. Prime Ministers.  For many astronomers, this time represents almost half a career and for people under 25, they have never known a world without the Hubble Space Telescope in it.

This exciting hangout will take a look at all of the things the Hubble Space Telescope has done for us, both scientifically and culturally with Dr. Martin Barstow, Pro-Vice-Chancellor, Head of the College of Science & Engineering, Professor of Astrophysics & Space Science and President of the Royal Astronomical Society.

Later in the hour, he will also introduce us to ATLAST, The Advanced Technology Large Aperture Space Telescope.  ATLAST is a NASA strategic mission concept study for the next generation of UVOIR space observatory. ATLAST will have a primary mirror diameter in the 8m to 16m range that will allow us to perform some of the most challenging observations to answer some of our most compelling astrophysical questions. We have identified two different telescope architectures, but with similar optical designs, that span the range in viable technologies. The architectures are a telescope with a monolithic primary mirror and two variations of a telescope with a large segmented primary mirror. The concepts invoke heritage from HST and JWST design, but also take significant departures from these designs to minimize complexity, mass, or both. ATLAST will have an angular resolution that is 5 – 10 times better than the James Webb Space Telescope (JWST) and a sensitivity limit that is up to 2000 times better than the Hubble Space Telescope (HST).

Please join +Tony Darnell Dr +Carol Christian  and +Scott Lewis as they discuss the impact of Hubble and this exciting new +NASA mission.

Studying Virtual Universes with Supercomputer Simulations

Studying Virtual Universes with Supercomputer Simulations
Dr. Greg Snyder, Space Telescope Science Institute

In extragalactic astronomy, observational studies span a huge range in size scales, cosmic times, wavelengths of light, and galaxy appearance. While we cannot directly watch the development of a galaxy over billions of years, this current era of dramatically increasing computer resources have made possible comprehensive predictions for galaxy evolution. Recent advances toward the goal of simulating realistic ³virtual universes² include the Illustris Project, one of several efforts beginning to reproduce key features of galaxy populations. These successes are only the first steps toward a loftier goal: the prediction of new astrophysics that can be tested by ever-improving telescope technology. Future improvements in computational galaxy formation may lead us there in the coming decades.
