It might sound like science-fiction but one day moon bases could be a reality. One thing which future lunar dwellers will need to be careful of is moon dust, as scientists have now declared it to be toxic.
Scientists have recently discovered an exoplanet that is approximately 1,500 light years away. The exoplanet, though, will soon evaporate and turn into dust because it is orbiting quite close to its parent star.
Was it just a day? On Sunday the world remembered the attacks of September 11, 2001. World leaders took time to give speeches about the tragedy that fell upon New York City, Washington D.C. and a rural field in Pennsylvania.
A number of traders from the United Arab Emirates were shocked when Customs discovered that the gold they had ordered from Ethiopia or Ghana, attractively priced, was nothing but worthless mud and dust.
There’s an old saying: Don’t mess with Mother Nature, because if you do she’ll come back and bite you where it hurts. And mess with her is what the Los Angeles Dept. of Water and Power did, forcing them to go back and clean up the mess they made.
The Martian dust is all over the planet. It’s so small that even the almost non-existent Martian atmosphere can produce winds strong enough to cover the planet with it. The problem is that the stuff is potentially dangerous for any landing.
Like flatulence that never goes away, gaseous ammonia and other odorous gases that result from animal manure can attach to dust particles, leaving behind matter that is both unpleasant and unhealthy for humans
This view shows a new picture of the dust ring around the bright star Fomalhaut from the Atacama Large Millimeter/submillimeter Array (ALMA). The underlying blue picture shows an earlier picture obtained by the NASA/ESA Hubble Space Telescope. The new ALMA image has given astronomers a major breakthrough in understanding a nearby planetary system and provided valuable clues about how such systems form and evolve. Note that ALMA has so far only observed a part of the ring.
The star Fomalhaut and the belt of dust surrounding it, as seen in the far-infrared by the Herschel Space Observatory. The ring of dust is created by the collision of thousands of comets every day.
