I hope that 2025 has been treating you well so far! Here in Baltimore the Cycle 4 Time Allocation Committee has not long finished its challenging task of selecting programmes for Cycle 4 observations, which will start on 1 July this year. Heartfelt congratulations to those of you who were successfully awarded Cycle 4 time! The competition was fierce given the unprecedented number of 2377 submitted proposals. Of the approved GO programmes, 30% were led by PIs in the ESA Member States, which is comparable to the fraction in Cycles 1 to 3. My sincere thanks to those of you who contributed your much-valued time and expertise on the external and topical panels, and the Executive Committees, to review the proposals and to select the top-ranked programmes for recommendation to the STScI Director.
As we look ahead to Cycle 4 with Webb, let me also remind you of the opportunity to propose for Cycle 33 observations with Hubble. The proposal deadline is on 10 April, and approved Cycle 33 observations will start on 1 November this year. For further details and more information on Hubble’s unique ultraviolet-optical capabilities see the Call for Proposals here.
Just two weeks after the Cycle 33 deadline comes another major milestone for Hubble, as we look forward to celebrating the 35th anniversary of its launch on 24 April 1990. As featured in this recent announcement, following a solicitation for proposals, ten institutions will host celebratory public events. If you are interested in your own institute participating in these celebrations, please contact us. Also, keep a lookout for newly processed Hubble images that we will be releasing in the run-up to the anniversary.
In 2025 we are also celebrating the 15th anniversary of the ESA/Hubble Picture of the Week. The series features a new image at the start of each week, drawing from Hubble’s vast archive and across the many different types of scientific targets that it has observed. This week’s image was the 775th image published in the series! If you have prime or parallel targets from your programmes that you think would make for an eye-catching image, please contact us.
Let me also bring to your attention a couple of opportunities to learn more about Webb observations and data analysis that ESA is supporting this summer. Firstly, on 27 June 2025 at the European Astronomical Society meeting in Ireland we are organising a Special Session on the JWST Data Pipeline, more details are available here. Further ahead, STScI is organizing its first JWST Summer School in Baltimore (4–15 August 2025), on the topic of high-redshift transients with JWST, with more details here.
Good luck with your Cycle 33 proposals, and I look forward to seeing many of you at the EAS meeting, if not before!

We are excited to share that the inaugural JWST Summer School will be held at STScI on 4–15 August 2025, on the topic of high-redshift transients with JWST.
With its superb sensitivity and infrared capabilities, JWST has opened a new and exciting window onto time-domain science. By detecting redder and fainter sources, JWST …
