... The discovery of such a large mass of dust should help us understand how supernovae slowly spread and fill galaxies with gas, dust, and small rocky particles, some of which may eventually end up in the next generation of stars and planets. ...
... Possible sources for the observed dust include dust wafted up from the atmosphere; dust coming from Phobos and Deimos, the two moons of Mars; dust moving in the solar wind away from the Sun; or debris orbiting the Sun from comets. ...

... Quartz dust seems to be a rather rare kind of dust in the universe, and it is not yet clear how the quartz dust observed around HD 15407A formed. ...
... The finding implies that the deaths of smaller, humbler stars may have supplied the early dust that seeded the myriad stars like our sun, and produced dust more efficiently than the big guns. ...
... Computer simulations have already shown that such gravitational tides can shape a dust ring into eccentricity, and findings from another т?? the eccentric dust ring around the star Fomalhaut т?? may be observational evidence for the process. ...
