An accumulation of shining clouds has been captured by NASA’s Curiosity rover on Mars. The accumulation took place after clouds arrival at a particular place.
Usually, a thin, dry, and cloudy atmosphere exists on the Red Planet. The clouds are found at the equator when the gap between Mars and Sun reaches to highest distance. The scenario ensures the coolest atmosphere on the planet which is necessary for the clouds.
However, this time the scientists found the formation of the clouds over NASA’s Curiosity rover earlier than expected time.
“If you see a cloud with a shimmery pastel set of colours in it, thats because the cloud particles are all nearly identical in size. Thats usually happening just after the clouds have formed and have all grown at the same rate,” said Mark Lemmon, an atmospheric scientist with the Space Science Institute in Boulder, Colorado.
“I always marvel at the colours that show up: reds and greens and blues and purples. It`s really cool to see something shining with lots of colour on Mars,” Lemmon said.
“Viewed just after sunset, their ice crystals catch the fading light, causing them to appear to glow against the darkening sky. These twilight clouds, also known as “noctilucent” (Latin for “night-shining”) clouds, grow brighter as they fill with crystals, then darken after the Sun`s position in the sky drops below their altitude, a US space agency said in a statement.
