How it works Diagram showing simulated light from an exoplanet and its companion star (far left) moving through the new ...

A coronagraph mimics this natural phenomenon with a circular mask that sits inside a telescope and selectively blocks the bulk of the sun's light. More recently, the development of a new class of ...

The Roman Coronagraph Instrument is a technology demonstration that will launch aboard the Nancy Grace Roman Space Telescope, NASA's next flagship astrophysics mission. Roman will have a field of ...

The coronagraph, which is roughly the size of a baby grand piano, is a sophisticated system composed of masks, prisms, detectors, and self-flexing mirrors that work together to block the glare ...

Engineers and scientists of the Max Planck Institute for Astronomy (MPIA), led by Oliver Krause, developed crucial optical elements for the Coronagraph ... with dedicated masks to make fainter ...

we designed a coronagraph with a variable‐diameter occulting disk (Hg mask). We present the description of the Hg‐mask coronagraph developed at the Observatório Nacional, Rio de Janeiro, and the ...

Masks work, she explained, as a filter, not as a sieve. Virus particles must weave around the layers of fibers, and as they do so, they may crash into those fibers and become trapped. Marr likened ...

115, No. 808 (June 2003), pp. 712-719 (8 pages) ABSTRACT We report a laboratory experiment to assess the performance and limitations of the four‐quadrant phase mask coronagraph we proposed 2 years ago ...

A coronagraph is used to block out the direct light of a star, allowing fainter objects like exoplanets to become discernible. The masks and active mirrors of the Roman Coronagraph could give the ...

NOAA today shared the first images from the Compact Coronagraph (CCOR-1), a powerful solar telescope onboard the new GOES-19 satellite. CCOR-1, the world's first operational, space-based ...

Zhang Hongxin, a researcher from the Changchun Institute of Optics, Fine Mechanics and Physics, works on the research of China’s first independently developed Spectral Imaging CoronaGraph.
