However, the researchers pointed out, the remaining 4 percent of the radio emission could be coming from as many as 100 billion very faint objects.

So Jewitt and Luu carried out two parallel surveys: they used the Palomar Observatory's Schmidt telescope equipped with conventional glass photographic plates to scan large areas of the sky for the very faintest objects, while also watching a narrow field of view in the plane of the planets for rare but slightly brighter objects using MIT's 1.3 - metre telescope fitted with a CCD.

Objects in the Kuiper Belt are difficult to detect because they are very faint.

«It's very difficult to see these faint moving objects in front of thousands and thousands of background stars,» Parker says.

Astronomers studying distant objects call these stars «foreground stars» and they are often not very happy about them, as their bright light is contaminating the faint light from the more distant and interesting objects they actually want to study.

Extreme adaptive optics also allows much fainter objects to be seen very close to a bright star.

The team has focused on a particular type of objects called Dust - Obscured Galaxy (DOG) that has a prominent feature: despite being very faint in the visible light, it is very bright in the infrared.

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.

The Dragonfly Telephoto Array used 14 - centimeter state of the art telephoto lens cameras to produce digital images of the very faint, diffuse objects.

Once more massive and brighter than Gacrux and so burnt out much faster, it is now probably a few hundred times fainter than Sol, with 0.6 to 1.4 times its mass and less than one percent of its diameter — a very dense object at planetary size.

Adaptive optics removes the blurring effects of the Earth's atmosphere, greatly increasing the acuity of astronomical images and allowing astronomers to study very faint and distant objects in the universe.

The HRS contrasted with the FOS in that it concentrated entirely on UV spectroscopy and traded the extremely faint objects for the ability to analyze very fine spectral detail.

This is because many of the inner Oort cloud objects are so distant that even very large ones would be too faint to detect with current technology,» says Sheppard.
