The moon will be closest to the Pleiades in the hours following sunset. Look high above the southeastern horizon in the hours following sunset on Jan. 27 to see the waxing gibbous moon shine alongside ...

A new high-resolution map of distant galaxies may help scientists understand the mysterious dark matter holding the universe ...

A research team has successfully imaged a nova in high resolution—and the images suggest that the nova was not a single, impulsive explosion. A nova is an astronomical phenomenon that occurs in a ...

When the world first saw the glowing orange ring of a black hole, it was not just a pretty picture. It was the visual proof ...

The breakthrough study made use of IXPE's unique X-ray polarization feature.

The IMS5420-TH white light interferometer opens up new perspectives in industrial thickness measurement of monocrystalline silicon wafers. Due to its broadband superluminescent diode (SLED), the ...

The new white light interferoMETER IMS5200-TH is designed for fast, high-precision inline measurements. It measures coating thicknesses from 1 µm to 100 µm with nanometer precision and an excellent ...

Accurately characterizing high aspect ratio geometries—such as narrow gaps, deep trenches, and deep holes—is becoming increasingly important across a wide range of technologies and industries. To meet ...

Abstract: White light interferometry is commonly illuminated using stable and long-lasting white light emitting diodes (LEDs). The measurement process is, however, susceptible to the spectral effects ...
