Announcement of the JWST Masterclass

From the desk of the ESA Hubble and JWST Project Scientist

Another exciting few months to write about. On the HST front, 1019 proposals have been received in response to the Cycle 27 Call by the deadline of April 7. There was a strong showing from the European community, who submitted 202 proposals (20%). The proposals requested a total of 24.454 orbits, the fourth highest in Hubble’s long life. Hubble is in high demand and the Telescope Allocation Committee (TAC) will have a very interesting time choosing the best of the best. We look forward to welcoming all our TAC colleagues to STScI in June. And stay tuned for those “Blacker” emails at the end of June.

Again related to Hubble, a four-year-long project is coming to an end. The Hubble Catalog of Variables will be officially released in September and you all will be able to use and exploit it. This will be a bittersweet moment, as the collaboration with colleagues at the National Observatory of Athens is winding down, but we are excited to anticipate all the creative and inventive ways you will use this catalogue and the great scientific results that will come out of it. Read here about this future announcement: the catalogue will be available for download, but there will also be an interface that will allow you to query the catalogue data interactively. Read here about this interface, which will be available through the eHST and which has been written by the very capable friends of the Archive team at ESAC.

On the JWST front, all is proceeding well — testing on the ground continues smoothly and JWST is on track for a launch date of March 2021. Read here an update from the JWST Project Scientists, and read here about a new initiative that ESA is spearheading in coordination with NASA/STScI and that will be of great interest to you all. If you would like to become an expert in planning JWST observations, here is your opportunity to attend the JWST Master Class that we are planning at ESAC in February 2020. You can find here the details and the application template (deadline is 3 June 2019). Do consider applying!

To our community of actively engaged astronomers: we have a new ESA/Hubble Press Officer! We say goodbye and good luck to Mathias Jäger and we welcome Bethany Downer, who joins our team with an impressive background in astronomical outreach. Read here about Bethany and how she can help you to advertise your scientific research. Do email her and say hi and let her know how she can help you.

Finally, we want to hear from you! Help us to make the science newsletter most useful and informative to you! Tell us what you want to know, tell us what you like and what we can improve. For 2019, we are planning to continue covering Hubble and JWST, and to bring you the most recent information. We would also love to include more of your science. If you’re interested, get in touch at Looking forward to hearing from you all!
