Quoted from The Next Web, this device's approach is different from the previous one. Therefore, this device does not use the lens but uses the laser in operation.
Thus, the laser is used to show the 3D movement of microscopic particles. The catch was then analyzed further. If it moves randomly, it is most likely not an object of life, but if it moves with a pattern it is likely that the organism is alive or alien.
This device has no moving parts, making it easier when it is fixed. Although intended for all space regions, researchers actually have specific goals in this study.
One of the concerns is Saturn's Satellite named Enceladus. The reason, Saturn's moon has a shell with a giant geysir that sends steam into space and has the potential to contribute to disseminating microorganisms.
Later, the device aims to find the vapors that Enceladus threw and discovered the possibility of microbial life. For trials, researchers have done so in Antarctica and plan to hold similar tests at the South Pole.
"We are trying to design microscope parameters that can tell about life on Earth, so if we can maximize this ability, we are confident enough to do the same on other planets," said Professor Jay Nadeau of Caltech who took part in the study.
For information, the search for life outside the Earth has actually been done for a long time. However, until now there has been no clear consensus among scientists to continue the various findings.
For that, the breakthrough done at Caltech is expected to help find out what is actually contained in rocks or water on other planets. Thus, it can encourage human knowledge to know other lives.
