A supernova has exploded in the galaxy M74, only 30 million light years away.
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.
Readers!
Every February I run a fund-raising drive during my birthday month. This year I celebrate my 72nd birthday, and hope and plan to continue writing and posting on Behind the Black for as long as I am able.
I hope my readers will support this effort. As I did in my November fund-raising drive, I am offering autographed copies of my books for large donations. Donate $250 and you can have a choice of the hardback of either Genesis: the Story of Apollo 8 or Conscious Choice: The origins of slavery in America and why it matters today and for our future in outer space. Donate $200 and you can get an autographed paperback copy of either. IMPORTANT! If you donate enough to get a book, please email me separately to tell me which book you want and the address to mail it to.
Please consider supporting my work here at Behind the Black. My analysis of space, politics, and culture, taken from the perspective of an historian, is almost always on the money and ahead of the game. For example, in 2020 I correctly predicted that the COVID 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. Every one of those 2020 conclusions has turned out right.
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.
3. A Paypal Donation or subscription:
4. Donate by check, payable to Robert Zimmerman and mailed to

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. ;)
