As per scientist study revealed at the American Astronomical Society meeting in Austin, the color of Milky Way our galaxy would appear like the shade of fine-grained spring snow in early morning light.
Although the color of the Milky Way is red than other spiral galaxies, but while it combined with its blue arms, its overall color is white as the shade of white halfway between an incandescent light bulb and the standard spectrum white on a TV.
The Milky Way’s red color indicates its star-forming days are coming to an end. An astronomer Jeffrey Newman said, “It’s entering its retirement when it won’t make anything new.”
With the University of Pittsburgh, Newman informed, “Understanding the color of the Milky Way allows us to compare other galaxies to it because for most galaxies all we can measure is how bright they are and what color they are. It’s really frustrating that that’s exactly what we can’t measure about the Milky Way from our position inside it.”
The Milky Way is a very typical galaxy on basis of type and numbers of stars, the analysis shows.
As per researcher the galaxies that have a similar number of stars and similar star birthrates as the Milky Way out of nearly 1 million galaxies in the Sloan survey and also its color is very close to as per of all the galaxies we see. This data has been combined from 1000 galaxies.
One more study has been conducted that Alien planets that may be in number of 160 billion planets are incredibly common in our own galaxy Milky Way.
As per six year long study, there are over 100 billion stars in our galaxy and each of them hosts at least 1.6 planets on average, bringing the number of likely alien worlds to more than 160 billion.
These planets are smaller, roughly like Earth, since low and mass planets appear to be much more abundant than large ones.
Arnaud Cassan, a study author of the Paris Institute of Astrophysics said, “This statistical study tells us that planets around stars are the rule, rather than the exception.”
It has discovered that three betrayed the presence of an alien planet around a star. One is a bit more massive than Jupiter, second comparable to Neptune and the third is a so-called “super-Earth” with a mass about five times that of our home planet.
Calculating the true number of alien worlds from data that is gathered by a variety of Earth-based telescopes which scanned millions of stars from 2002 to 2007 for microlensing events may be quite a bit larger than 160 billion, as some planets hug their host stars more closely than 0.5 AU, and others are more far-flung than 10 AU.
However till date we should see our galaxy populated not only with billions of bright stars, but imagine them surrounded by as many hidden extra solar worlds and around 700 planets discovered with 2,300 “candidates” found by NASA’s Kepler space telescope awaiting confirmation.
