Researchers at Ben-Gurion University have designed a new satellite imaging system that can transform the imagery and economics obtainable from earth-based telescopes and space-based cameras.
“This is a discovery that entirely modifies the prices of astronomy, space exploration, aerial photography, and so on,” claims candidate form the BGU Department of Electrical and Computer Engineering, Angika Bulbul, to the media in an interview.
In a paper posted in Optica, the scientists show that nanosatellites the size of milk cartons set up in an annular (spherical) configuration were capable of capturing pictures that match the lens-based, full-frame, or concave mirror systems’ resolution employed in new telescopes.
“Various earlier assumptions related to long-range pics were wrong,” Bulbul claimed. “We discovered that you only require a small fraction of a telescope lens to get quality pictures. Even by employing the perimeter aperture of a lens we were able to get similar picture resolution in comparison to the entire aperture region of lens/mirror-based imaging systems.”
On a related note, Astronomers with the ALMA (Atacama Large Millimeter/submillimeter Array) have performed one of the most profound studies ever of protoplanetary disks. These disks are quasi-steady circumstellar disks of dust and gas, from which stars might gradually form or be in the process of shaping forming.
The top models for of formation planet hold that stars are born by the eventual accumulation of gas and dust within a protoplanetary disk, starting with molecules of dust that coalesce to make larger and larger rocks, until planetesimals, asteroids, and planets form.
This hierarchical procedure must take many millions of years to understand, recommending that its affect on protoplanetary disks might be most widespread in more mature & older systems. Mounting proof, on the other hand, shows that is not always the situation. ALMA’s previous observations of small protoplanetary disks disclosed surprising and striking structures, comprising prominent gaps and rings, which seem to be the trademarks of planets.
