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.

In earlier observations, emission from two or more faint objects often was blurred or blended into what appeared to be a single, stronger source of radio waves.

Like many applications, bigger is often better in space — the larger a space telescope is, the more light it can gather, helping it capture higher - resolution images and spot fainter objects.

Redshift is a measure of how much the Universe has expanded since the light left a distant source and can only be determined for faint objects with a spectrograph on a powerful large telescope such as the Keck Observatory's twin 10 - meter telescopes, the largest on Earth.

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.

Still, the zodiacal light illuminates the heavens there and obscures faint objects; it is the main diffuse background at visible wavelengths.

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.

Faint objects like galaxies and globular clusters are clear to the naked eye from here; the night I visited, the night sky was bright enough to read by, the Milky Way was lit up like a celestial highway and faint meteors continually peppered the heavens.

M. Keck Observatory on the summit of Mauna Kea, Hawaii.

It is impossible to get a good photograph of the entire cluster because the galaxies are faint objects scattered across 15 degrees of the sky, and a large angle photograph would be swamped by thousands of foreground stars in our own galaxy.
