In a faraway galaxy, seven supernovas explode all at once

Galaxy Arp 220, located 250 million light-years from Earth, is home to seven different supernova explosions all going on at the same time. We've never seen so many stars exploding simultaneously in the same galaxy.

A team of astronomers at Chalmers and Onsala Space Observatory found that all seven supernovas went off in the last sixty years (allowing for the 250 million years for the light to reach Earth, of course). In cosmic terms, that's pretty much no time at all, as European Southern Observatory astronomer Rodrigo Parra explains:

"In Arp 220, we see far more supernovae than in our galaxy. We estimate that a star explodes in Arp 220 once every quarter [century]. In the Milky Way, there is only one supernova per century."

The astronomers believe it's proof that Arp 220 is one of the most efficient galaxies in the universe when it comes to making stars...and, ultimately, blowing them up. There's so many stars that have formed in that galaxy that there's always plenty of potential supernovas, even allowing for the fact that exactly when each star explodes in its own lifetime can vary by a whole lot more than sixty years. Team member John Conway adds:

Seven with one blow. Seems a bit odd, unless some sort of chain reaction has occurred. Coincidences would seem to be easily ruled out.

Seriously, this is most interesting. Please ping me in the future on cosmology/astronomy news (especially deep space material like this.)

I'm familiar with E.E. "Doc" Smith, but ya lost me with the BEM reference. Loved the Lensman series, and the Skylark series. Have I missed some other works of his?

VOGON CAPTAIN:
[On Speakers] People of Earth your attention please. This is Prostectic Vogon Jeltz of the Galactic Hyperspace Planet Council. As you no doubt will be aware, the plans for the development of the outlying regions of the western spiral arm of the galaxy require the building of a hyperspace express route through your star system and, regrettably, your planet is one of those scheduled for demolition. The process will take slightly less than two of your Earth minutes thank you very much.

MANKIND:
[Yells of protest]

VOGON CAPTAIN:
There’s no point in acting all surprised about it. All the planning charts and demolition orders have been on display at your local planning department in Alpha Centauri for fifty of your Earth years so you’ve had plenty of time to lodge any formal complaints and its far too late to start making a fuss about it now.

MANKIND:
[Louder yells of protest]

VOGON CAPTAIN:
What do you mean you’ve never been to Alpha Centauri? Oh for heaven sake mankind it’s only four light years away you know! I’m sorry but if you can’t be bothered to take an interest in local affairs that’s your own regard. Energise the demolition beams! God I don’t know…apathetic bloody planet, I’ve no sympathy at all…

Affirmative B.E.M.s = "BUG EYED MONSTERS". In reference to "Doc", [example from Lensmen Series] it might be the Ploorians in their winter stage, big eyes for very dark days & nights.

Generically, see many SF Pulp Magazine covers from 40s and 50s, where BEMs were generally reaching for an incredibly pulchritudinous but scantily clad human female. Given that the mean audience of these magazines were mid-adolescent males tending towards what later generations would call nerd-dom, a good marketing strategy.

Ah yes, the good old days when men were men and sheep were ...
