Gastly Green Oorts....Maybe.

In a combined image from the Spitzer Space Telescope and the Chandra X-ray Observatory, Nasa/Jet Propulsion Laboratory published the image to the left. It is the dusty remains of a collapsed star, a supernova G54.1 + 0.3. The Chandra data is in blue and the Spitzer data is shown in green and red-yellow.
"The material ejected in the explosion is now blowing past these stars at high velocities" according to Tea Temim from Harvard Smithsonian Center for Astrophysics.
The data in green is due to the shorter wavelenghts detected by the Spitzer Space Telescope.
"The white source near the center of the image is a dense, rapidly rotating neutron star, or pulsar that was left after a core-collapse supernova explosion."
The original article didn't provide information about the spherical stars that are shown in green or yellow, but one can see a faint greenish sphere surrounding the presumed stars. Even in the image above, there are two yellowish stars to the left of a yellowish star with a spherical halo of dust.
The questions of consideration "Does this image show stellar objects (stars) that are surrounded by a cocoon or analogous Oort Cloud?" If so, then the second question "If these are analogous Oort Clouds around the other stars, then how common are stars that have analogous Oort Cloud structures?

Planetary Evolution.

Eventually, the Earth will loose the hydrogen molecules that forms the watery world that we live upon, in about 3 Billion years the planet will be radically different than it is today. The art of Alfred T. Kamajian, provides a conceptual lens into the dynamics of planetary evolution.
