Artistic representation of PSO J318.5-22 The journal Astrophysical Journal Letters published an article describing the discovery of an extremely rare - the first of its kind in the world, which is flying freely in the open space. Scientists have no idea where it came from planet PSO J318.5-22 disappeared and where her star. Age PSO J318.5-22 northrop grumman career estimated at 12 million years old, which is very small space standards, that is, the planet northrop grumman career was formed literally just that. Gas giant mass six times larger than Jupiter northrop grumman career is now at a distance of 80 light years from Earth. Planet discovered by accident when on data taken Hawaiian telescope Pan-STARRS 1 (PS1), launched a program to find brown dwarfs. Because of its extremely low temperatures these stars are very faint light in the red range. The search engine has processed 4 petabytes of photos and gave PSO J318.5-22 as one of the anomalous results. The object was much redder than most red dwarfs. Additional studies have shown that the properties of this gas giant similar to those of similar northrop grumman career gas giants around young stars, but there is no star. "We had never seen a flying freely in space object, like this, - says Dr. Michael Liu (Michael Liu) from the Institute of Astronomy at the University of Hawaii. - I have often wondered whether there are single objects in the universe, and now we know that it is so. " Have recently been discovered for thousands of planets outside our solar system, but very few of them can be observed directly through a telescope. Even if it is possible, the presence of a number of bright lights interfere with their learning. In the case of the planet PSO J318.5-22 no noise there, so that scientists there is a rare opportunity to learn how to develop gas giants like Jupiter shortly after birth.

I think that happens in the universe so that the substances in the environment is not enough to form a full-fledged star. That's kind of nedozvezda-pereplaneta. northrop grumman career It is possible that such objects in the universe a lot. We do not know about them, because they are difficult to detect due to the fact that they have a small mass and are off.
Under dark matter refers northrop grumman career to the extra weight, which affects the speed of rotation of stars in galaxies, and nothing more. What are these "other properties" you mean?
Usually have in mind, they do not participate in electromagnetic interactions and always-in gravity. As an example, the neutrino. If two such particles are let through thick lead somewhere 10 ^ 31 meters, only one will be absorbed. And the sun is emitted their oh how much. So much of what is possible on earth and their detection in real time frames.
Neutrino-like part of the hidden mass is what I meant. And according to my consideration, it is the lightest neutrino particle (electron neutrino) with a non-zero rest mass, which means that the theoretical possibility to enter the galactic orbit neutrino dig.
Why would it? If dark matter is a lot of "alone" northrop grumman career of the planets and asteroids, they are very difficult to detect otherwise than by gravitational effects. Although it all - the usual stuff, "participating in the electromagnetic interaction." northrop grumman career Here is the Kuiper Belt of the Sun, for example. Nothing prevents suggest that galaxies there is something similar, but in a very large scale
All that trudnoobnaruzhimo by electromagnetic interactions and not detectable by an electromagnetic and strong interactions is called the hidden mass. Which are divided into two types of 1-baryonic northrop grumman career dark matter. These include the intergalactic gas, brown dwarfs, wandering the planet, etc. booolshim very difficult to detect an object involved in the electromagnetic and strong interactions, and consisting of or having in its composition baryons. 2-baryonic dark matter does not (people-dark matter simply). That is referred to them all that is not involved in the electromagnetic and strong interactions. They are estimated to be between northrop grumman career 20 to 30 percent. They rank, such as neutrinos, axions and other exotic objects (quark stars, the space-time distortion, etc.) 3-dark energy.
But gas accumulations oh what great and wandering planet oh what tiny. Also gas throughout. Bunches northrop grumman career happen, and there is also sparse and in the galactic halo in the first type of people it is hard to notice. Well, everyone knows that it's there. For the lightest northrop grumman career prefer to be on the distant orbits, and heavy on close orbits to the central galactic black hole. As a fact, if it were not for the gas accumulation, the center of the galaxy would have covered us at night that was, would be as bright as day.
Maybe the world everywhere, even more than the stars are formed. In the immediate vicinity of the sun most of the stars - red dwarfs of low luminosity. Maybe the planets of even lower luminosity an order of magnitude more. By the way, the density of gas clouds is very small, something like 1 atom on of cubic
