A supernova has exploded in the galaxy M74, only 30 million light years away.
This is one of the closest supernovae in recent years. Though it is still brightening and has reached 12th magnitude, it is not expected to brighten to naked eye visibility (about 6th magnitude). Astronomers however have spotted the progenitor star in archival Hubble images, which they have identified as a M-type red supergiant that was also particularly bright in the infrared.

Please consider supporting my work here at Behind the Black. Your support allows me the freedom and ability to analyze objectively the ongoing renaissance in space, as well as the cultural changes -- for good or ill -- that are happening across America. Fourteen years ago I wrote that SLS and Orion were a bad ideas, a waste of money, would be years behind schedule, and better replaced by commercial private enterprise. Only now does it appear that Washington might finally recognize this reality.
In 2020 when the world panicked over COVID I wrote that the panic was unnecessary, that the virus was apparently simply a variation of the flu, that masks were not simply pointless but if worn incorrectly were a health threat, that the lockdowns were a disaster and did nothing to stop the spread of COVID. Only in the past year have some of our so-called experts in the health field have begun to recognize these facts.
Your help allows me to do this kind of intelligent analysis. I take no advertising or sponsors, so my reporting isn't influenced by donations by established space or drug companies. Instead, I rely entirely on donations and subscriptions from my readers, which gives me the freedom to write what I think, unencumbered by outside influences.
You can support me either by giving a one-time contribution or a regular subscription. There are four ways of doing so:
1. Zelle: This is the only internet method that charges no fees. All you have to do is use the Zelle link at your internet bank and give my name and email address (zimmerman at nasw dot org). What you donate is what I get.
2. Patreon: Go to my website there and pick one of five monthly subscription amounts, or by making a one-time donation.

Maybe two thousand years from now Hubble data will still be available to do this same kind of research but have we planned on how to store the data that long?
Really dumb question here, when did this event happen? this says that the event was thirty million light years away, how far out into the universe can Hubble see with in real time parameters?
Hubble can see galaxies that are many billions of light years away. Individual stars, however, can only be seen by Hubble in galaxies that are much closer, as in the case of M74, 30 million light years away.
I go into the details at much greater length in my book on Hubble, The Universe in a Mirror.
I wonder how close a Earth like planet could be to a supernova (or hyper nova) like that and stay habitable?
Days like today I’m glad Earths ni a thinly populated section of the galaxy. ;)
