Sentences with phrase «faint objects orbiting»
Initial data came from the TRENDS (TaRgetting bENchmark - objects with Doppler Spectroscopy) high - contrast imaging survey that uses adaptive optics and related technologies to target older, faint objects orbiting nearby stars, and precise measurements were made at the W. M. Keck Observatory on the summit of Mauna Kea, Hawaii.

XMM - Newton is on a distended orbit that takes it one - third of the way to the moon; this keeps it out of Earth's shadow long enough to stay pointed at — and collecting photons from — the same faint object for more than a day.
For example, an instrument on one satellite could block the glare of the sun or a distant star, making it possible for a camera on the other to image faint objects such as the sun's ghostly corona or exoplanets orbiting a star.
Ground - based and orbiting telescopes employ exquisitely sensitive detectors to search for objects that are much farther away, and much fainter, than could have been detected just a few years ago.
David Jewitt of the University of Hawaii and Jane Luu, now at Stanford University, found a faint slow - moving object beyond the orbit of Pluto a year ago, and a second in March.
Astronomers are stuck with such indirect methods of detection because current telescope technology struggles to image very distant and faint objects - especially when they orbit close to the glare of a star.
