About 100 000 light years across, Messier 66 is the largest galaxy in the ?Leo Triplet?, three interacting spiral galaxies about 33 million light years from us. This new Hubble Space Telescope image shows that M66 seems to have been through the mangle. ... Why not go out to see if you can find these distant islands of stars? ...
... Radio emission at around 90 GHz from star-forming galaxies is expected to be strongly dominated by the free-free component due to ionising radiation from massive, short-lived, stars. We present high surface-brightness sensitivity observations at 90 GHz of the nearby star-forming galaxy Messier 66 with resolution of about 9 arcsec (corresponding to a physical scale of about 500 pc) and analyse these observations in combination with archival lower frequency radio and mid-infrared measurements. ...

... I see the same problem all the time in undergraduate assignments: someone comes up with an answer that is clearly, wildly, hopelessly wrong (e.g. the mass of some star is 0.7 kg, or an asteroid is travelling at 1010 m s-1 (faster than light), or the Earth took 1011 years to form (much longer than the age of the universe). ... This means that every valid equation should work equally well, regardless of the units you use (as long as they are self consistent). ... Do you think this could be correct? ...
