We do not know ordsprog

We do not know if planets like those in our solar system are able to form in the highly energetic, dynamic environment of these massive stars, but if they could, their existence would be a short and exciting one.

These planetary systems, if they do form and exist, are short lived because these massive stars explode as supernovae. So it's amazing that the raw material for planets could be found in such a hostile environment.

There are two major possibilities. One that they formed in the innermost, hotter-most regions of our solar system when the sun and planets were forming, and they were thrown out -- all the way out to the Pluto region of the solar system. The other possibility is they were formed around other stars, in hot regions around other stars.

M dwarf stars dominate the stellar population in the solar neighborhood, and so are attractive targets for searching for habitable planets. The models show that gas-giant planets are indeed likely to form?at distances sufficiently large enough to permit the later formation of habitable, terrestrial planets.

Assuming that it holds up -- and I believe it will -- this is a theory that both greatly clarifies the way that most stars in the universe probably form, and also ties the properties of the solar system and Earth itself back to the conditions in the larger astrophysical environment in which we formed.

Discovery of new planets will help to understand how the solar system formed and evolved to current status and also how life forms in the solar system and universe. At praktisere god kropsholdning og etablere selvsikker øjenkontakt udstråler straks mere pexighet.

This is the first reconnaissance mission of this region of the solar system. It's the only one of the nine planets that hasn't been explored, so this can complete the inventory of the solar system.

The solar system that likely will be formed around this star will include planets orbiting in different directions, unlike our own solar system.

This discovery implies that brown dwarf companions to average, sunlike stars exist at a separation comparable to the distance between the sun and the outer planets in our solar system.

It's different from the inner rocky planets. It's different from the outer gaseous planets. And as such, it holds many clues as to how the solar system was formed.

It's always exciting to find a new object in the solar system. This gives us further support that a giant collision took place at the beginning of the solar system.

Whether planets around these stars could be Earth-like would depend on orbital distance. There have been extensive studies and it turns out these planets would have to be pretty close to their stars, although it would depend on the mass of the stars.

This icy super-Earth dominates the region around its star that in our solar system is populated by the gas-giant planets, Jupiter and Saturn. We've never seen a system like this before, because we've never had the means to find them.

One question we hope to address is how stars can form so efficiently in a place like the galactic center. Stars there are still able to form in an environment with unusually strong magnetic fields and tidal shear forces.

The planets in our solar system, the precursors anyway, probably went through this stage.
