I didn't know DeLay was a dwarf?
Racist statement by Harvard astrobubbas, of all people.
I'm offended by the racist 'black hole' remarks. Astronomers need to come up with a politically correct name, like bottomless pit. You know, like the 'War On Poverty' bottomless pit.
Space are cool.
"I nearly fell out of my chair at the telescope when I saw one star change its speed by a staggering 750 miles per second in just a few minutes," said Smithsonian astronomer Warren Brown, lead author of the paper reporting the find."
The changing speed implies the orbit elliptical. When the pair gets close they whip past each other.
More info here:
"We have discovered a detached pair of white dwarfs (WDs) with a 12.75 min orbital period and a 1,315 km/s radial velocity amplitude. We measure the full orbital parameters of the system using its light curve, which shows ellipsoidal variations,..."

And I am offended that you (geneeric) can’t post an article about a fascinating astronomical pehnomenom without some clueless doofus trying to make a political joke about it. Grow up, Charley.
I can see why! I mean, my God, an object with at least the mass of one hundred Jupiters is being yanked around like it's a rag doll... jaw hits floor.
Thanks for the links.
You’re welcome. Thanks for posting the interesting article.
“its companion has more than half the mass of the Sun and is Earth-sized. A penny made of this white dwarf’s material would weigh about 1,000 pounds on Earth.”

a half ton penny!!!
“The two white dwarfs are circling at a bracing speed of 370 miles per second (600 km/s), or 180 times faster than the fastest jet on Earth.”
I hope the scientist didn’t provide that stat - I’d guess it was the “science writer”.
Assuming the “fastest jet” can go Mach 4 (about 4400 ft/s), or .83 mi/s, 370 miles per second would be 456 times faster.
(Mach 4 is actually faster than any current publically known jet. The SR-71 Blackbird could fly about Mach 3.5.)
I'll put it on my calendar...;-)
Wow, in only 900,000 year from now? Those scientists must be waiting with baited breath!
Call me then and see if I'm still interested.
I'm just doing what the liberal media does. A conservative, with no racist intent or thought, can utter something that the liberal media can exploit and that conservative gets beat over the head, for days or weeks.
Oh! And, I've had days and days and days and days and days of diversity training to sensitize me to every little possible politically incorrect word or phrase. You'll be getting more of these post as time passes. The possibilities for offense are unlimited. I've been trained to be a very sensitive person.

But a feather compared to a penny made from the material of a neutron star --which would weigh a billion tons.
Astronomers plan on watching this to the end? 900,000 years from now?
