If a space examine rescued microbial life on another planet, would scientists know it when they saw it?

A new paper by JPL and Caltech researchers looks during how holographic imaging competence be used to detect microbes — including those on other planets.

Identifying germ by steer is severe adequate on Earth, even for experts. To a exposed eye, germ demeanour like featureless blobs — not distinct a vegetable grains that competence approximate them in a sample.

A form of holographic imaging could help. A new paper in a biography Astrobiology highlights a showing process called digital holographic microscopy, that uses laser light to constraint 3-D images. Whereas customary microscopes can usually perspective a skinny cut of a dump of water, this process adds some-more depth.

The paper was co-authored by Chris Lindensmith of NASA’s Jet Propulsion Laboratory, Pasadena, California; Jay Nadeau of Caltech; and Manuel Bedrossian, a Caltech connoisseur student.
