Astronomers have discovered black widows and redbacks in space. While these cosmic objects don't kill and eat their mates, the stars share their eight-legged counterparts' violent behavior toward companions.
In addition to the run-of-the-mill spider stars, the researchers also discovered a bizarre black widow-redback crossbreed. The scientists used the now-destroyed Arecibo telescope in Puerto Rico to discover the weirdo stars.
Spider stars are types of millisecond pulsars, or neutron stars that act like precise clocks in the sky, whirling around at least once every 30 milliseconds and flashing like a lighthouse with each rotation. Neutron stars, the tiny, compressed cores of old, exploded stars, often rip material from other stars locked in binary orbits with them and use the push of that infalling material to get up to pulsar speed. Spider stars are rare and special versions of these stars though:

So David Bowie was right. There really are Spiders from Mars!
Does that mean we really only have Five Years?
I will ask that Ground Control ask Major Tom what he thinks.
Why don’t they ever show an actual photograph of what they Believe they have found.
This is all a joke.
They must be in need of funding is how I take it.
🤔
How’d the spider kill the telescope?

Black widow stars matter!
How fast do they have to be going to do that?
Why don’t they ever show an actual photograph of what they Believe they have found.
Because it is so far away it’s just a smudge of light and radio waves. It may not even exist at this time. That’s how long it takes the light to get here.

I've seen ignorant FR posts, but yours is a candidate for a new record!
1. "Photographs"? Do you not understand that radio waves and visible light occupy radically different sections of the EM spectrum?
2. Why do FRLuddites always characterize publications of scientific advances as:"They must be in need of funding..."?
3. Do you have any concept of what the Arecibo Telescope looked like -- before it was destroyed in a violent physical collapse? Or its reflector diameter?
The "joke"'s on you...
I clicked on the link, it repeated the same information three times and never seemed to wind up to a clean conclusion.
Good footage of the collapse, and the structure before the collapse, is here:

It is almost better to start at 2:00, and watch through 4:00, which gives a good impression of the huge scale of the instrument. Then go back to the beginning and be seriously impressed by the collapse. Or at least I was.
13 is perhaps better addressed to “All”. ;-)

Venomous-Spider Star?
Barbra Streisand?
...was that the one from the James Bond movie GoldenEye?
Yes. That one

The antivenin for a Venomous spider star is hard to get and weighs tons for a single drop.
LOL!
