Did you know there are 33 thousand asteroids and 20 new comets are aimed at Earth

Infrared Space Telescope WISE found in the solar system, new dangerous objects. Did you know there are 33 thousand asteroids and 20 new comets are aimed at Earth?

Infrared Telescope Facility WISE (Wide-field Infrared Survey Explorer) was launched by NASA in December 2009. He was supposed to review the sky at infrared wavelengths. In order that the telescope could find even the coldest objects of its detectors were cooled by liquid hydrogen. Stockpile was only enough hydrogen for ten months.

During this time the telescope had to do more than 1.8 million images of the sky in the infrared range. Its main objective was to study the main belt between Mars and Jupiter. A few days ago NASA specialists reported on the results of the project WISE.

Scientists say it’s especially important to learn more about near-Earth objects (NEOs), which are asteroids and comets with orbits that come within 28 million miles (45 million kilometers) of Earth’s path around the sun, since some of them could potentially pose a collision hazard with our planet.

- Just one year of observations will greatly expand our catalog of data on “near-Earth objects, and other small celestial bodies, – the representative of NASA’s Lindley Johnson.

But astronomer’s directory spokesmen said to put it mildly, it caused a slight shock and it was what scared everyone the most was that Astronomers have found in the solar system about 33 thousand previously unknown asteroids. 

The results of this work, which will be combined with observations in the visible range, will help determine the size and composition of hazardous space objects. By the way, in addition to the asteroids that were discovered, 20 new comets and 134 near-Earth objects were also revealed. Also, the telescope confirmed the discovery of a huge number of known bodies, for example, about a hundred-plus new comets.

If I didn’t know better I would think some of our space neighbors are throwing rocks at us.

Comets swirling over head

NASA's NEOWISE mission recently finished the survey, which was a secondary job for the agency's Wide-field Infrared Survey Explorer, or WISE, space telescope. WISE fulfilled its primary goal of photographing the entire sky 1 1/2 times in infrared light last year. "WISE has unearthed a mother lode of amazing sources, and we're having a great time figuring out their nature," said Edward (Ned) Wright, the principal investigator of WISE at UCLA.
