By examining infrared data taken earlier by the Spitzer Space Telescope, they discovered a swath of dust particles ranging in size from 0.1 to 20 microns (finer than a split hair) that added up to the mass of a large asteroid and, based on their warmth, were strewn about 1.8 Earth — sun distances from the star.

Picture distant blue stars brighter than the full moon at night, shining through the spidery veins of dust and gas that hang through the nebula like cobwebs.

«We're not sure whether these stars are holding onto reservoirs of gas much longer than expected, or whether there's a sort of «last gasp» of second - generation gas produced by collisions of comets or evaporation from the icy mantles of dust grains,» said Meredith Hughes, an astronomer at Wesleyan University and coauthor of the study.

The discovery of jets pushing away from dust - shrouded protostars at hundreds of miles per second was the first hint to astronomers that star formation was a far more chaotic process than they had envisioned.

If the star is closer than 1,300 light - years, extinction from gas and dust in the interstellar medium can not explain the current level of dimming.

Produced by stars, the dust causes light to look redder than it really is when observed visually, which can make it difficult for astronomers studying properties of stars.

New observations of the star using the SPHERE instrument on the VLT have clearly revealed how the brilliant light of VY Canis Majoris lights up the clouds of material surrounding it and have allowed the properties of the component dust grains to be determined better than ever before.

That explains why radio astronomers have found more complex molecules in the warmer, more active star - birthing regions of dust clouds than in the colder, darker areas.

The events included «superflares» of more than 100 million °C, arcing far into space and striking disks of gas and dust around the young stars.

Or, as Joni Mitchell put it in her song «Woodstock» more than a decade later, «We are star dust.»

NGC 253, a giant that's somewhat smaller than the Milky Way, is experiencing a starburst: For its size, it's converting gas and dust into new stars at a rapid clip, 2.8 solar masses per year.

But we saw that the dips were deeper in blue [light] than they were in the red, which indicates that something more transparent, like dust, is crossing in front of the star,» Boyajian says.
