Sentences with phrase «faint planets»

Earth's turbulent, starlight - blurring atmosphere is also a severe obstacle to imaging faint planets from ground - based observatories, and most experts agree that the solution is to use space telescopes.

The instrument, called the Gemini Planet Imager (GPI), was designed, built, and optimized for imaging faint planets next to bright stars and probing their atmospheres, and studying dusty disks around young stars.

By removing much of the starlight in this way, astronomers hope to detect very faint planets circling the star or achieve precision measurements of the stellar surface — feats that otherwise would require a single mirror hundreds of feet across.

«This technology will lower the contrast floor so that we can detect fainter planets,» says Mazin.

Because starshades work with practically any telescope, one on WFIRST could cast a deeper shadow and see fainter planets than a coronagraph.

We usually use it to look for very faint planets in the close vicinity of nearby stars, by painstakingly observing them one by one,» said Pueyo.

Called VISIR, the instrument will be equipped with a coronagraph — a mask to block out the light of the star so that the much fainter planets can be seen.

The term is a misnomer: Observing a number of vaguely round, cloudlike objects in the sky during the late 18th century, Sir William Herschel thought they resembled faint planets.

The DARK - speckle Near - infrared Energy - resolved Superconducting Spectrophotometer (DARKNESS) is designed to take images with much higher contrast ratios, allowing astronomers to spot extremely faint planets around bright stars.

Now's the time to spot the faintest planet visible to the unaided eye.

The findings could also prove useful in optical systems, such as microscopes and telescopes, for viewing faint objects that are close to brighter objects — for example, a faint planet next to a bright star.

Telescopes with mirrors much smaller would struggle to resolve any faint planets flitting like fireflies around Alpha Centauri's stars.

«We were able to separate the light of the faint planet from the light of the much brighter star and to see that they were both growing and glowing in this very distinct shade of red.»

The strange mask would fly tens of thousands of miles in front of the telescope and could, if positioned precisely, cancel out the light of the host star completely, revealing the faint planets.

Then, astronomers like myself can make out the faint planet companions orbiting the star.
