with Dr Steve Crawford and Professor Jayanne English
In Episode 17 of The Cosmic Savannah, we discuss space telescopes! We talk about the amazing Hubble Space Telescope and the upcoming James Webb Space Telescope (JWST).
We sit down with Dr Steve Crawford from the Space Telescope Science Institute (STScI) in Maryland, USA, and formerly SALT. Steve explains how his team deliver data from space telescopes to scientists on Earth.
Professor Jayanne English from the University of Manitoba, Canada, then gives us insight on how she and others create the beautiful images we see from the Hubble Telescope. And how the myriad of data collected is incorporated into one beautiful image.
This week’s guests:
The CTB 1 supernova remnant resembles a ghostly bubble in this image, which combines new 1.5 gigahertz observations from the Very Large Array (VLA) radio telescope (orange, near center) with older observations from the Dominion Radio Astrophysical Observatory’s Canadian Galactic Plane Survey (1.42 gigahertz, magenta and yellow; 408 megahertz, green) and infrared data (blue). The VLA data clearly reveal the straight, glowing trail from pulsar J0002+6216 and the curved rim of the remnant’s shell. CTB 1 is about half a degree across, the apparent size of a full Moon.
