There is a write up in Nature on a super nova. This should be of
interest to TO because of the age of the universe discussions.

I'm sorry but you have to pay to read it.
The bottom line is that these super nova are common. This was the 4th
one that they detected in April (by mid month) in the region of sky that
they were scanning. A super nova occurs in a galaxy around every 100
years and there are billions of galaxies. So these stars are dying all
the time.
This particular one, Super nova MUSSES1604D, is 546 mega parsecs from
earth. Light can travel one parsec in around 3.26 years, so this star
died over 1.5 billion years ago. They use this type of super nova to
estimate distance because of the uniformity of the light given off by
the type of super nova that it is.
The thing is that these stars are dying in galaxies near and far and it
takes light different amounts of time to get to us. What does this mean
for YEC? Eddies group is no longer YEC. They don't have to worry about
facts like these because they changed their interpretation of the Bible.
A day can be billions of years long and the sun and moon are no longer
created on the fourth day.
Really, it takes light around 100,000 years to cross our galaxy and
other galaxies are obviously not inside of our own. These super nova
are obviously popping off on a regular basis in galaxies different
distances away from ours. How could we be seeing the death of stars
over a billion light years away from us if the universe is less than
20,000 years old? They observed 4 super novas in half a month, and the
the different times that they could have died encompasses billions of
years, so how did the light from the 4 super nova in different galaxies
reach earth witnin 17 days of each other? The closest galaxy to earth
is 2 million light years away and these 4 galaxies are spread across
quite an arc of sky. Really these galaxies span distances where it
would take from millions of years to billions of years for light to
reach us and yet we can observe 4 super nova within 17 days.
