Incoming comet ISON appears intact to Hubble

(Phys.org) —A new image of the sunward plunging Comet ISON suggests that the comet is intact despite some predictions that the fragile icy nucleus might disintegrate as the Sun warms it. The comet will pass closest to the ...

Even brown dwarfs may grow rocky planets

(Phys.org)—Astronomers using the Atacama Large Millimeter/submillimeter Array have for the first time found that the outer region of a dusty disc encircling a brown dwarf contains millimetre-sized solid grains like those ...

Earth is getting dustier, model suggests

(PhysOrg.com) -- If the house seems dustier than it used to be, it may not be a reflection on your housekeeping skills. The amount of dust in the Earth's atmosphere has doubled over the last century, according to a new study; ...
