US Hubble Space Telescope photos show that Pluto is changing colors

Washington, Feb 8 (THAINDIAN NEWS) The US Hubble Space Telescope photos show that the Pluto is changing colors, and its ice-sheets are also shifting. Pluto was demoted to a ‘dwarf planet’ status in 2006. NASA released the photos on Thursday, which show that Pluto is much red, than it has been since the past several decades.
To the naked eye it shows that it has a yellow-orange tinge, but the astronomers say that compared to the previous pictures, now Pluto is 20% more redder. The pictures also show that the icy frozen nitrogen on Pluto’s surface is glowing, and it is brightening in the North, whereas it is darkening in the South.
“It’s a little bit of a surprise to see these changes happening so big and so fast. This is unprecedented,” said astronomer Marc Buie of the Southwest Research Institute. Astronomers also say that Pluto’s surface is changing much more than the other planets. And this is quite a dramatic change, because one season lasts more than a century (120 years to be precise) in Pluto. Pluto didn’t change in color from 1954 to 2000. Astronomers are clueless as to why the redness changed so dramatically in the recent years.
