Dave Green's research: G1.9+0.3

G1.9+0.3 has been identified as the youngest known Galactic supernova remnant, about 150 years old at most.

Below a 4.86-GHz image of G1.9+0.3 from observations made in 2008 is compared with a matched-resolution 1.49-GHz image from observations made in 1985 (move cursor on/off).

G1.9+0.3 at 4.86 GHz from 2008-Mar-12 and at 1.49 GHz from 1985-Apr-16 (when cursor over). (For further details, see the Green et al. 2008 paper listed below.)
