Engineers have developed an innovative water treatment method that could help Mars explorers

  • No comments
A catalyst that breaks down a chlorine compound (perchlorate) in water could help clean the soil on the planet Mars during manned habitation on Mars. It is a substance that accumulates in plants and makes them toxic if it is not removed from the water
From the artist's illustration above, you can get an impression of how nearby objects will look to the NEO Surveyor. Their faint heat signatures will appear as a band of dots that appear in red in this image, for our convenience. That way they will look different from the stars in the background, which are painted blue in the picture. Hunting for near-infrared objects will also allow scientists to determine not only the location and orbit of the objects but also their size. And it is the size that determines the extent of their destruction if they hit the Earth. Image: NASA

The spacecraft will conduct its survey in infrared. Telescopes on Earth have found most of the nearby objects cataloged so far, but the remaining ones are very difficult to find in visible light

The frozen side of the moon

A new study by Weizmann Institute of Science scientists and their research partners in the USA indicates that at least some of the water on the moon may be trapped in much more accessible places - in pits and small depressions.

An artist's rendering of a potential companion to the Sun, which theorists believe evolved in the Sun's natal cluster and then was lost. If proven, the companion sun theory would add credence to theories that the Oort cloud formed as we see it today, and the ninth planet was captured rather than formed in its place. Qualifying: M. Weiss

Did the sun start life as half of a pair of twin stars?

  • 14 תגובות
Harvard University scientists say the Sun may once have had a binary companion with a similar mass. If the theory is confirmed, the presence of an ancient companion star increases the likelihood that the Oort cloud formed as it is observed
