Understanding how galaxies evolve is one of the most active fields of modern astrophysics. I will show how the HST -- which can be used as a time machine to look back at galaxies in the distant past -- has transformed our knowledge of galaxy evolution. I will also show how the supermassive black holes in the centres of galaxies play a key role in the transformation of galaxies over cosmic time, and discuss the likely fate of our own galaxy, the Milky Way!
Knowledge Anchor’s notes - Conway Mothobi FRAS
When NASA launched Space Shuttle Discovery STS-31 with the HST as payload, the launch commentator dubbed the HST “our window on the Universe” and to this day the HST continues to serve humankind with astounding images and new knowledge of our Universe enriching our scientific enterprise.
The NASA/ESA HST image of the cluster Westerlund 2 and its environs was released to celebrate HST’s 25th year in orbit and a quarter of a century of new discoveries, stunning images and outstanding science. The image was awarded to HST @25 Communicator Conway Mothobi by the Hubble Heritage Team, the European Southern Observatory & the Space Telescope Science Institute for outstanding public outreach and engagement. This image (aka Celestial Fireworks) together with other (new) images and videos compiled by the Hubble Heritage Team will be on display in the Street, John Dalton M1 5GD Thu Nov 16 and Fri Nov 17
