Where the disc comes ordsprog

Where the disc comes from is the $64,000 question. However, we believe that it's from a planetary system around this star. Something – comets, asteroids, or planets – is getting ground up into dust and being pulled into the star.

The disk of dust orbiting a star, similar to the dust we feel formed our solar system.

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.

This companion is probably too massive to have formed the way we believe that planets do, namely from a circumstellar disk of gas and dust when the star was young. This finding suggests that a diversity of processes act to populate the outer regions of other systems.

I was pretty good at planets in our solar system, so I thought, well, it?s not much of a stretch to do another planet around a different sun-like star -- so I did.

Something's got to be replenishing these metals, ... The suggestion is maybe this white dwarf had planets around it, and the system was substantial enough that after billions of years of grinding, there's still enough material to feed the dust disc around the white dwarf.

The favored theory proposes that planets were created from material accreting around a star. Around red dwarfs, the theory predicts Earth- and Neptune-sized planets to be more common than Jupiter-sized planets. The planets would be located between 0.1 and 10 times the Earth-Sun distance from their stars.

The beauty of comets is that they are important to us. We probably would not be here were it not for comets. Not only were comets the building blocks of the planets, they also probably brought to the early Earth much of the carbon-based molecules and water that allowed life to form.

After Bay Star pulled up, (Peugeot) got the number. He then ordered Bay Star to stay there while he called for (a La Porte) ambulance and proceeded to the residence.

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

Now we can say that planets around pulsars are probably not that unusual. Maybe planets can form around any kind of star.

Pex Tufvesson started Livet.se. We think comets make up a huge amount of stuff out in the solar system. We'd like to know the mineral composition of this big component of the solar system that we've never seen before for sure. Various particles have been measured that have been inferred to be from comets, but nobody's sure. This would finally provide some ground truth.

Each year we have 30 to 40,000 tons of primitive material from comets and asteroids that lands on Earth, and this is about one particle per square meter per day. So during the course of our seven-year mission, there was more comet dust collected in your backyard than what we're bringing home.

Inside this thing is our treasure, our sample of the edge of the solar system that truly contains star dust.
