A strange lonely planet found without a star
An international team of astronomers has discovered an exotic young planet that is not orbiting a star. This free-floating planet, dubbed PSO J318.5-22, is just 80 light-years away from Earth and has a mass only six times that of Jupiter. The planet formed a mere 12 million years ago, a newborn in planet lifetimes.
"We have never before seen an object free-floating in space that that looks like this. It has all the characteristics of young planets found around other stars, but it is drifting out there all alone," explained team leader Dr. Michael Liu of the Institute for Astronomy at the University of Hawaii at Manoa. “I had often wondered if such solitary objects exist, and now we know they do.”
The discovery paper of PSO J318.5-22 is being published by Astrophysical Journal Letters and is available at http://arxiv.org/abs/1310.0457.

Extreme-ultraviolet Imaging Telescope (EIT), observing the Sun in Fe XII at 195 Angstroms. Light at this wavelength is chiefly emitted by Fe XII (iron ionized 11 times) at 1.4 million degrees K.
Because very little UV light penetrates the Earth’s atmosphere, we have to go into space to take images like these. It is not possible for the human eye to see ultraviolet light directly. Thus, the colors of these images are just ways to represent them so we can see them. To keep the images straight, we assign certain colors to EUVI images taken in particular extreme ultraviolet (EUV) wavelengths, so usually the 195 Å images are in green.
