Hubble Space Telescope
2 reportsHubble Space Telescope is a space telescope that collects radiation with calibrated optics and detectors across a defined wavelength range. Performance and scientific value are assessed through instrument calibration and telescope optics, with calibration and engineering limits shaping the usable evidence.
New findings about Hubble Space Telescope are placed alongside observing programs and instrument calibration, with separate attention to survey data products. One line of support comes from instrument characterization, and a separate test comes from independent analyses; together they clarify instrument calibration, but the comparison must account for the fact that sensitivity, resolution, and selection effects constrain interpretation.

Metasurface Grating Demonstrates Compact Solar Magnetic Field Mapping
A polarization-sensitive metasurface grating has matched conventional instruments in mapping solar magnetic fields, offering a route to smaller, simpler, and potentially more robust hardware for future space-based solar telescopes
Hidden White Dwarfs Detected Near Earth in Red Dwarf Binaries
Astronomers have identified four white dwarfs concealed by red dwarf companions within 65 light-years, using ultraviolet observations from the Hubble Space Telescope to reveal these elusive stellar remnants
