A unique new material that shrinks when it is heated and expands when it is cooled could help enable the ultra-stable space telescopes ...

When the search for habitable exoplanets requires a 1,000 times more stable telescope than James Webb Space Telescope, even ...

The barrier plate made of Schott ZERODUR microcrystalline glass (thermal expansion coefficient ± 0.03 × 10 ⁻⁶/℃) can maintain dimensional stability under high-energy ion beam (200keV) bombardment ...

Semiconductor etching imposes strict requirements on the corrosion resistance, thermal stability, and optical purity of materials in plasma environments. Special glass components have become key ...

Earlier materials such as Invar and Zerodur already keep Webb and the upcoming Roman telescope remarkably stable, but HWO will need 1 000 × better. So NASA’s Astrophysics Division awarded ALLVAR a ...

A unique new material that shrinks when it is heated and expands when it is cooled could help enable the ultra-stable space telescopes that future NASA ...
