TESS
1 reportTESS is a space telescope that collects radiation with calibrated optics and detectors across a defined wavelength range. Performance and scientific value are assessed through detector array, pointing system, and science archive, with calibration and engineering limits shaping the usable evidence.
The documented context of TESS includes instrument calibration and survey data products, with separate attention to spectral or imaging analysis. Interpretation of survey data products depends on the agreement between instrument characterization and independent analyses; the result is bounded by the possibility that sensitivity, resolution, and selection effects constrain interpretation.

Hubble Reveals High-Speed Gas Bullets from Rare Helium Nova in Milky Way
Astronomers using Hubble and other observatories have observed V445 Puppis, the Milky Way's only known helium nova, ejecting dense gas clumps at speeds up to 32 million kilometers per hour
