We are delighted to announce the latest in a series of ESA-sponsored conferences, in collaboration with STScI, which highlight the scientific impact of the Hubble and James Webb Space Telescopes. After much anticipation of their complementary capabilities, we are now in the remarkable period of having these two pioneering observatories in science operations at the same time — the much-heralded Golden Age for UV-optical-IR space astronomy has arrived!

Hubble, a long-standing partnership between NASA and ESA, is continuing to surprise and inspire us with new results and breakthroughs. As we look ahead to the 35th year of science operations, its use and powerful complementarity with other facilities continues to evolve, with the community finding novel and innovative applications for its unmatched ultraviolet-visible capabilities.

We are now also witnessing the first exciting results from JWST, a collaboration between NASA, ESA, and the CSA. With performance beyond our expectations, JWST is quickly transforming our view of the universe on all scales, from new insights in our Solar system and nearby exoplanets, to revealing the formation and growth of the very first galaxies and black holes.

These two observatories are now combining to give us unique views of stars, gas and dust in the universe. These span the processes of nearby star and planet formation, the properties of the interstellar medium in galaxies near and far, the production of dust in supernovae and evolved stars, and new insights into the dust content and star formation in the early Universe.

Of course, Hubble and Webb are far from working alone. A broad range of ground-based and space-borne facilities are helping to provide us with a multi-wavelength view to unlock our understanding of the Universe. These include the rich legacy from the Gaia mission, the start of science operations with Euclid to explore the dark Universe, the exquisite resolution and sensitivity of ALMA in the sub-mm, and the imminent first light of the Rubin Observatory. Looking ahead, the second half of the decade will bring major new space missions, such as Roman, PLATO and ARIEL, and the first light of the European Extremely Large Telescope.

The science program will feature a combination of invited and contributed talks, with the objectives to:

  • Highlight the latest Hubble and Webb results in studies of stars, gas and dust over all scales, with a focus on results with strong synergies between the two missions and with other facilities.
  • Identify key topics for new programs and initiatives that will harness the powerful combined capabilities of these two observatories. 
  • Explore future synergies of Hubble and Webb with other existing and planned facilities.
  • Look ahead to the future scientific questions that will shape astrophysics into the 2030s and beyond.
