Sentences with phrase «coronagraph is a telescope»

A coronagraph is a telescope that is designed to block light coming from the solar disk, in order to see the extremely faint emission from the region around the sun, called the corona.

Not exact matches

A competing team is refining an alternative approach, called an internal coronagraph, which blots out starlight from inside the telescope.

Franck Marchis, an astronomer at the SETI Institute in Mountain View, California, a partner with Project Blue, says such a telescope, outfitted with a coronagraph, would be able to obtain an image.

Chakrabarti's suborbital rocket flights were made possible through NASA funding, as was the bulk of recent progress in high - performance coronagraphs for space telescopes.

Reaching a seamless synergy among this holy trinity — high - performance coronagraph, deformable mirror and instrumental stability — is so formidable it has scarcely been achieved in laboratories here on Earth, and has never even been attempted on a telescope in space.

The only way to plug the leaks is to make a practically perfect coronagraph, then to feed it with a beam of starlight shaped to similar perfection both by deformable mirrors as well as by the extremely precise and stable pointing of a telescope.

Europe's Spectro - Polarimetric High - contrast Exoplanet REsearch (SPHERE) and the U.S. - backed Gemini Planet Imager (GPI) are attached to big telescopes in Chile and employ sophisticated masks, called coronagraphs, to block out the light of the star.

Moreover, because Alpha Centauri A and B are so bright and close together, Webb's coronagraph could only block the light of one star while the light from the other beats down for tens of hours on the telescope's delicate, irreparable sensors — a risk that mission operators are unlikely to take.

A device called a coronagraph can be built into a telescope to block most of the photons from a distant star's glow, allowing the dim light from a planet to pass into the telescope's sensors and create a glare - free image.

Simulation of a Solar System twin at a distance of 13.5 pc as seen with HDST (12 m space telescope) and a binary apodized - pupil coronagraph, optimized using the methods described in N'Diaye et al. (2015).

The image is based on a state - of - the - art design for a high - performance coronagraph (that blocks out starlight) that is compatible for use with a segmented aperture space telescope.

A National Research Council (NRC) report released today lauds the additional science that could be obtained using hardware transferred to NASA from the National Reconnaissance Office (NRO) for the next large space telescope, but worries about the cost and potential impact on the balance of programs within NASA's astrophysics portfolio, especially if a coronagraph is added.

The telescope would have a suite of instruments: cameras, spectrographs, and a coronagraph for blocking out a star's blinding glare so that any dim, accompanying planets can be directly imaged.

Project Blue will demonstrate and test coronagraph and wavefront technologies similar to ones that could be used on much larger future space telescopes currently being studied by NASA (e.g., HabEX, LUVOIR), and thus help to retire technical risks and hone the observing techniques and data processing algorithms for those missions.
