Rarely do we get the opportunity to seethe a classic David Bowie song while thumb through the late science news , but this workweek we take in the replication of spiders on Mars . No , they ’re not real arachnoid scuttle across the Red Planet ’s surface — instead they ’re part of a geologic lineament known as araneiform terrain . These dark , snap - comparable complex body part form when carbon dioxide seasonally erupts from the planet ’s Earth’s surface and resemble spiders scurrying across the terrain when viewed from a large height . And now , for the first timethey have been recreated on Earth .
But these " spiders " are not the only thing we ’ve had to keep an eye on from space : There is thenew ' mini - moon’taking a little twist around our major planet ; the discoverythat Earth may have once worna Saturn - like ringing ; and the prospect of quad trashleading us to intelligent foreigner .

A giant mosasaur ’s fossilized jaw fragmentsstill take for the animal ’s blunt , mushroom - work teeth .
The two fossil fragments , discovered in Texas , give us an insight into the life style ofGlobidens alabamaensis , which may have reached lengths of up to 20 foot ( 6 meters ) . The teeth show the brutal force mosasaurs brought to contain on their prey .

3 bold ways cities are already adapting to climate change
Milan ’s marble frontal and narrow-minded , stone - paved street see elegant and timeless . But all of that stone emits heat and does nothing to absorb rain , and temperatures and flooding in the posh Italian city are only predicted to increase in the coming decennary .
In Jakarta , black floodwaters already festinate into home every wintertime along the Indonesian city ’s many rivers . That water is filled with sewage and harbors disease , but many people ca n’t give to move . before long , clime variety will put more of Jakarta — and many other low - lying cities — below ocean level .
And in desiccate San Diego , water is already treated like a precious commodity . As drought increase in the coming years , protecting this resourcefulness will become even more important .
Human - caused mood change is transmute weather patterns and shift ecosystem around the globe . urban center will have to respond , and some are already taking bluff steps .
Each of these three citiesoffers a dissimilar roadmap for climate adaptationthat has lessons for other places around the humanity . And while no single plan of attack will be a silver bullet , each offers a hopeful visual sensation of how we can instruct to live and fly high on a warming satellite .
