The Scientific and Cultural Impact of Hubble; Meet ATLAST, a Next Genera...
Ζωντανή μετάδοση στις 9 Οκτ 2014
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.
