A BIZARRE picture shows what looks like a hulk plume of fume stretching 900 miles over a aspect of Mars – notwithstanding glow being unfit on a Red Planet.
Astronomers have been examination a extraordinary cloud for some-more than a month by cinema beamed behind from a European examine encircling a planet.
It has remained in place given Sep 13 over Arsia Mons, a volcano nearby a Martian equator, a European Space Agency said.
But Arsia Mons has been archaic for around 50million years and no volcanic activity is producing a cloud, reports Space.com.
And glow is unfit since there is really small oxygen in a skinny atmosphere, that is mostly CO dioxide.
The ESA pronounced a same orbiter spacecraft, named Mars Express, and a predecessors have speckled identical clouds during slightest 3 times before.
The cloud structures all shaped around a same time in a Martian year.
And that’s not a coincidence, scientists say.
ESA boffins reckon a cloud contains H2O ice and has been combined by breeze issuing along a side of a 12-mile-high, 150-mile-wide volcano.
The underline is what scientists call an orographic or lee cloud, that forms downwind of an obstacle.
The cloud changes over a march of a day as windy patterns on Mars vary.
Scientists study hundreds of images of a cloud have beheld it grows over a march of a morning, stretching westwards along a equator for adult to 930 miles.
It might also be influenced by particles still in a atmosphere from a large dirt charge that engulfed Mars progressing this year.
In Jul a Mars Express orbiter detected what could be a large subterraneous lake of glass water, lifting hopes it could means life.
