These earthly godfathers of Heaven's lights, that give a name to every fixed star, have no more profit of their shining nights than those that walk and know not what they are.

Supernova Cinematography: How NASA’s Roman Space Telescope Will Create a Movie of Exploding Stars

Universe Today - Mon, 07/21/2025 - 2:29pm

The Nancy Grace Roman Space Telescope isn't due to launch until May 2027, but astronomers are preparing for its science operations by running simulated operations. One of those involves supernovae, massive stars the end their lives in gargantuan explosions. Research shows that the Roman could find 100,000 supernovae in one of its surveys.

HWO Could Find Irrefutable Signs Of Life On Exoplanets

Universe Today - Mon, 07/21/2025 - 2:29pm

Searching for habitable exoplanets will require decades of work, new technologies, and new ideas. A lot of that effort seems to coalescing around the Habitable Worlds Observatory (HWO), a proposed mission expected to launch in the early 2040s that would be capable of directly imaging potentially habitable worlds, and, importantly, detecting features about them that could prove whether or not they host life as we know it. A new paper by exobiology specialists in Europe and the US, led by Svetlana Berdyugina of ISROL in Locarno, Switzerland, details an observational plan with HWO that could definitely prove that life exists on another planet - if they’re able to find one where it does anyway.
