NASA's Chandra X-ray Observatory and the National Radio Astronomy Observatory's Very Large Array have combined to discover the youngest supernova in the Milky Way galaxy.
At only 140 years old the supernova is younger than Cassiopeia A, the last known supernova in our galaxy which occurred around 1680. It had been missed by optical telescopes on Earth because it occurred close to the center of the galaxy and is embedded in a dense field of gas and dust, making it a trillion times fainter according to a NASA statement.

How could it be only 140 years old? It took longer than that for the light to arrive at Earth. This tar is close to the center of the galaxy?
It wouldn’t be in color if it were any older.
I think it’s saying that astronomers are detecting X-rays given off 140 years after the supernova occurred.
I think it means its 140 years since the light started arriving on Earth. Then again, I think I recall Mike Wallace reporting from its destruction in 1868.
optical center, not physical center.......
I knew I'd seen it somewhere before!
Well, it's like you walk into a movie and you look at the screen, and you say, "Gee, it looks like I missed the first 140 years."
LOL
I thought this was a thread about Miley Cyrus.
