Astronomers in Asia became aware of this object in 1181 when it flamed out as a supernova, Helfand said. Going on this historical record, present-day astronomers calculated that the remnant star should have cooled down to about 35.6 million degrees Fahrenheit by now. In fact, Helfand said, it is only about 1 million degrees C., making it too cool for a neutron star.

Jeez, is it too much to ask the reporter to use the same units in the same paragraph???

The Washington Post Article on this subject is even worse. No indication of the units!

Neutron stars cool off by radiating tiny particles called neutrinos. After 10 years, such a star's temperature should be about five million degrees. After that, it cools more slowly.

Given its age, Helfand expected the temperature of 3C58 to be a bit less than two million degrees.

"Our observations show in the case of this remnant that the temperature is far lower than that and the energy being radiated is down by at least a factor of 10 from (what was expected)," he said.
