Astronomers using NASA s Hubble Space Telescope have traced the locations of five brief, powerful radio blasts to the spiral arms of five distant galaxies.
Called fast radio bursts (FRBs), these extraordinary events generate as much energy in a thousandth of a second as the Sun does in a year. Because these transient radio pulses disappear in much less than the blink of an eye, researchers have had a hard time tracking down where they come from, much less determining what kind of object or objects is causing them. Therefore, most of the time, astronomers don t know exactly where to look. ....

James Webb Space Telescope/MIRI

A full list of people from across the UK that are playing an active role in the JWST can be found on this page.
In March 2021 Space Telescope Science Institute (STScI) announced the selected JWST General Observer programs for Cycle 1. The selected proposals were prepared by more than 2,200 unique investigators from 41 countries, including 43 US states and territories, 19 ESA member states, and 4 Canadian provinces. More detailed information about the approved proposals can be found here.
Due to impacts from the ongoing Coronavirus (COVID-19) pandemic, as well as technical challenges the launch of the NASA/ESA/CSA James Webb Space Telescope on an Ariane 5 rocket from Europe’s Spaceport in French Guiana is now planned for 31 October 2021. This decision is based on a recently completed schedule risk assessment of the remaining integration and test activities prior to launch. Previously, JWST was targeted to launch in March 2021. ....

Looking back in time
NASA’s James Webb Space Telescope (JWST) will look further back in time than any other telescope - to 400m years after the Big Bang. JWST is a collaboration between ESA, NASA and the Canadian Space Agency, due for launch in late 2021 as the replacement for the Hubble Space Telescope.
The four key goals of the JWST are:
to search for light from the first stars and galaxies that formed in the Universe after the Big Bang
to study the formation and evolution of galaxies
to understand the formation of stars and planetary systems ....
