At times, enough gas builds up for the dwarf to collapse, leading its carbon to fuse nearly instantly and the dwarf to explode in a Type I supernova, which can outshine a galaxy for a few months.

CFBDSIR J1458 + 1013b May be the first evidence of a new type of brown dwarf, called a "y spectral" object, that more closely resembles a planet than any other type of brown dwarf.

The observations also show for the first time that a white dwarf can create a cavity around it before blowing up in a Type Ia event.
