Two of the farthest supernovae ever detected have been found by using a new technique that could help find other dying stars at the edge of the universe. The two cosmic blasts occurred 11 billion years ago. The next-farthest large supernova known occurred about 6 billion years ago. Jeff Cooke from the University [...]

This technique will be tough to use for getting spectra.
BTW, 11 billion years ago was an era when type 1a supernovae were an extreme minority.
