Radioactive Decay Of Titanium Powers Supernova Remnant

Supernova remnant SNR1987A is located 166 000 light-years away in the Large Magellanic Cloud. The light from the stellar explosion arrived at Earth in 1987, and has since provided astronomers with a natural laboratory to monitor how the brightness of a supernova changes over time.

The first detection of titanium-44 in supernova remnant 1987A. ESA’s Integral space telescope made the detection in the energy range between 65 keV and 82 keV, which brackets two emission lines produced during the decay of titanium-44, at 67.9 keV and 78.4 keV.

The detection required over 1000 hours of observation time with Integral.
