Nova outburst are true multi-wavelength and probably multi-messenger sources, emitting copious flux from the radio range to gamma-rays; a nearby symbiotic nova may also have a measurable neutrino flux. I observe novae in X-rays to study the physical parameters of the massive white dwarfs in novae, and to obtain the spectra of the ejecta. The latter reveal new - or seldom observed - atomic physics. I will summarize how our findings are constraining binary evolution, and how we learn new facts about violent astrophysical shocks.

Rubin Observatory is an optical/near infrared telescope, featuring a wide-field optics, with the world largest CCD camera (3.2 Gigapixels!) in its focal plane. The presentation will highlight the first results from the Observatory, including the first images obtained at the end of 2024 with the Rubin Commissioning Camera. It will also show the Rubin First Look images from the full-size LSST camera. Dr, Madejski will also highlight some of the tools available to reduce and analyze the Rubin data.
