This star survived a close call with a black hole. Eventually, it will become a planet - CNN
(CNN) A red giant star strayed too close to a supermassive black hole in a galaxy 250 million light-years away. Instead of being gobbled up, the star survived -- but it's not in an ideal situation, either. In a drawn-out process of destruction that leads to a kind of renewal, the star will transform into a planet.

Scientists Release Incredible Video of Black Hole Spewing Matter
After an international coalition of scientists released the first-ever image of a black hole last year, we now have the ultimate follow-up: a video of a supermassive black hole spewing a brilliant jet of particles.

The video, part of a new research paper published in the journal Astronomy & Astrophysics this week, actually comes from the same observation of the black hole image conducted by the Event Horizon Telescope (EHT) initiative, as Science Alert reports .
News | Spitzer Telescope Reveals the Precise Timing of a Black Hole Dance
Black holes aren't stationary in space; in fact, they can be quite active in their movements. But because they are completely dark and can't be observed directly, they're not easy to study. Scientists have finally figured out the precise timing of a complicated dance between two enormous black holes, revealing hidden details about the physical characteristics of these mysterious cosmic objects.
The OJ 287 galaxy hosts one of the largest black holes ever found, with over 18 billion times the mass of our Sun. Orbiting this behemoth is another black hole with about 150 million times the Sun's mass. Twice every 12 years, the smaller black hole crashes through the enormous disk of gas surrounding its larger companion, creating a flash of light brighter than a trillion stars - brighter, even, than the entire Milky Way galaxy. The light takes 3.5 billion years to reach Earth.
The Black Hole of Luxury Watch Repair - The New York Times
Customers are used to waiting, waiting, waiting until their timepieces are returned. Is that patience about to end?

For all their expertise in wooing prospective buyers, luxury watchmakers have long been criticized for neglecting clients from the moment a purchase is completed.
"What we care about is selling a watch, not repairing a watch," said Ricardo Guadalupe , chief executive of the Swiss watchmaker Hublot. He was referring to the industry's collective tendency to ignore after-sales service, although, he added, that mind-set has begun to change.

Astronomers Identify 'Missing Link' Mid-Sized Black Hole
Researchers used data from NASA's Hubble Space Telescope and two X-ray observatories to find the black hole, which was in the process of destroying a nearby star.
Black holes are extremely dense objects possessing gravitational pulls so powerful that not even light can escape.
The newly identified black hole is more than 50,000 times the mass of our sun. It sits about 740 million light years from Earth in a galaxy containing far fewer stars than our Milky Way. A light year is the distance light travels in a year, about 9.5 trillion kilometers.
Little black hole orbits large black hole / Boing Boing
NASA published this animation showing a little black hole (150m solar masses) whirling around a large black hole (18bn solar masses), punching through its accretion disc like an energetic puppy doing donuts through a bead curtain.
Two massive black holes are locked in a dance at the center of the OJ 287 galaxy. The larger black hole is surrounded by disk of gas; it is also orbited by a smaller black hole that collides with the disk, producing a flare brighter than 1 trillion stars. But because the system's complex physics affects the smaller black hole's orbit, the flares occur irregularly.
Scientists Discover Pair Of Dancing Black Holes Regularly Ejecting Energy
A team of scientists discovered a pair of orbiting black holes that regularly produce outbursts of galaxies. Based on their study, most of the outbursts occur every 12 years.
The scientists were able to spot the black holes after their energy outburst was detected by NASA's Spitzer infrared telescope. Details of their observations were presented in a new study published in the Astrophysical Journal Letters .
The black holes are collectively known as OJ 287. They exist in a galaxy that's about 3.5 billion light-years from Earth's neighborhood. While one of the black holes is relatively small, which is about 150 million times more massive than the Sun, the other one is supermassive.
