Celebrating NASA’s 40-Year Legacy of Infrared Astronomy from Space

Robert Hurt, Caltech/IPAC
Over the last year and a half, the world has been amazed by the incredible fidelity of the Webb Space Telescope's infrared view of the universe. Yet 2023 also marks anniversaries for two landmark missions that forged the path of infrared astronomy from space. IRAS, the Infrared Astronomical Satellite, opened the astronomical community's eyes to the vast possibilities of the infrared universe 40 years ago. And 20 years ago, the Spitzer Space Telescope began plumbing new depths in the exploration of infrared celestial wonders. Dr. Hurt will look back across four decades of space-based infrared astronomy to examine how our understanding of the universe was fundamentally changed by accessing this non-visible part of the light spectrum from outside of Earth’s obscuring atmosphere.

Buongiorno secondo me : per andare più in là ,vedere in oltre mare,fare una giubbalarga nel cannocchiale , come diceva Aristotele, Copernico e Leonardo da Vinci. Una tripla majior ,in relazione di scala con un zoom partitario in prima decade ; un applien' dei cristalli liquidi del vetro,un arrangiatura di livello al cannochiale. E infine un obloe ,di vedetta considerevole. Una bella Santa Maria, come quella del copernicano, del navile. Tanti auguri e buoni saluti. -+......

Is nasa planning another upgrade to Hubble as it did on last time ?

[@Birbface]

don't think so, the 4th upgrade was supposed to be the last. It's past its project completion date, I think they're just going to continue to use it for as long as it functions.
