The astronomers hope to track down in masses cosmic objects with the infrared cameras of the probe, which can hardly be found in visible light. Read more:
In connection with the star announced in the prophecies and also with the discovery of Sedna, which indicates the existence of a second sun in our solar system, Nemesis, a report is interesting, which can contribute to the possible discovery of this star.
The report says that changes in the sky can now be detected. The question then arises that when Nemesis more or less is heading directly towards us, then its position will hardly change and will it then not be difficult to detect it.
I am now quoting excerpts from the report:
The whole sky on over a million pictures: About seven months after its start a Nasa probe has once taken photos of the firmament in infrared light.
The „Wide-field Infrared Survey Explorer“, WISE, revolves around earth over the poles and is to track down millions of so far unknown objects. The probe took photos on 1.3 million pictures - everything from asteroids to far away galaxies, ...
The astronomers hope to track down in masses cosmic objects with the infrared cameras of the probe, which can hardly be found in visible light. To it belong for instance dark asteroids and cool stars, called brown dwarfs, which do not radiate in the visible, but intensively in the infrared range. Unlike visible light infrared rays also penetrate dust clouds.
The registration of the whole sky through WISE helps ..., to find through immense and different amounts of heavenly bodies, ...
Over the next three months the probe is to scan half the sky again. That way one wants to get onto the trail of further hidden asteroids, stars and galaxies. The comparison with the previous photos shows the scientists changes in the sky.
The eyes of WISE are a gigantic improvement in comparison to the previous infrared investigations, ... "We will find millions of heavenly bodies, which never before have been seen."
The sky is explored in four infrared wave ranges, with a speed, which is hundreds of thousands times greater than with earlier projects. Infrared light, which the human cannot see, has greater wave lengths than visible light.
The objects discovered with the camera are catalogued and used as navigation aids with future missions. Besides Nasa hopes for insights into the size and composition of asteroids - important information for the assessment of possible collision dangers.
