The development of the algorithm that made it possible to create the first image ever of a black hole was led by computer scientist Katie Bouman while she was still a graduate student at MIT. Bouman shared a photo on Facebook of herself reacting as the historical picture was processing.
The algorithm, which Bouman named CHIRP (Continuous High-resolution Image Reconstruction using Patch priors) was needed to combine data from the eight radio telescopes around the world working under Event Horizon Telescope, the international collaboration that captured the black hole image, and turn it into a cohesive image.
Bouman is currently a postdoctoral fellow with Event Horizon Telescope and will start as an assistant professor in Caltech’s computing and mathematical sciences department, according to her website.
The development of CHIRP was announced in 2016 by MIT and involved a team of researchers from three places: MIT’s Computer Science and Artificial Intelligence Laboratory, the Harvard-Smithsonian Center for Astrophysics, and the MIT Haystack Observatory. As the MIT described it three years ago, the project sought “to turn the entire planet into a large radio telescope dish.”
Since astronomical signals reach the radio telescopes at slightly different rates, the researchers had to figure out how to account for that so calculations would be accurate and visual information could be extracted.
As MIT explained:
Bouman adopted a clever algebraic solution to this problem: If the measurements from three telescopes are multiplied, the extra delays caused by atmospheric noise cancel each other out. This does mean that each new measurement requires data from three telescopes, not just two, but the increase in precision makes up for the loss of information.
The algorithm then reconstructed and refined the original images to prepare the final historical image of the black hole. CHIRP can also be used for any imaging system that uses radio interferometry.
So much data was collected by Event Horizon Telescope that it had to be shipped to the MIT Haystack Observatory on half a ton of hard drives.

12 Best Uses For Old Computer Keyboards
Maybe you want to wear your love of keyboards on your sleeve, but earrings and charm bracelets are just a little too ostentatious for your taste. Enter the subtler and more stylish buttons and cufflinks. Not only is this a more discreet way of keeping your old keyboard close, but it’s also among the easiest projects we have for you.
You’ll only need a few supplies, at least one of which you already have at hand. There aren’t any scissors or saws, and you won’t be using any power tools. All you need is your old keyboard, an adhesive like epoxy, and the base of a cufflink or button, both of which you can find at your local craft store or online.
Before you get started, however, take a moment to inspect your keyboard. Consider the wide array of buttons, each with its own special function. Now choose your favorites. Those are the keys you want to carefully remove. If you’re making cufflinks, you’ll need at least two keys. If you’re making buttons, the sky’s the limit.
Now take out a flathead screwdriver — the only tool you’re going to need — and pop the keys you’ve chosen off of the keyboard frame. Once you’ve got them all liberated, generously apply adhesive to the back side of each key and jam the cufflink or button base right in there. Wait for it to cure and you’re ready to attach them to your favorite threads.
28% Of Car Lovers Most Want To Own This Banned Vehicle
In a SlashGear poll with 590 U.S. respondents, 27.97% said they would love to own Lamborghini Diablo Strosek. The Italian supercar is not street legal in the U.S. because it’s too fast. If pushed to the limit, the Lamborghini Diablo can exceed 200 mph — this made it the fastest car when it was released in 1990. But it was a German designer known as Vittorio Strosek who modified it and made it even more difficult for it to pass the FMVSS regulations. Because of the 25-year rule, you’re only allowed to import a Lamborghini Diablo that was produced between 1990 to 1997.
The second most popular option in the poll was the Porsche 959, which was picked by 25.25% of the respondents. Just like Lamborghini Diablo, Porsche 959 is super-fast but it doesn’t exceed 200 mph — the best it can do is 198 mph in the Sport variant. However, the real reason Porsche 959 was never sold in the U.S. is that the automaker didn’t want to have its very expensive cars crash tested by NHTSA. Despite the Porsche 959 quickly selling out after it was released, the manufacturer was making a loss selling the car — and if NHTSA crash tested a minimum of four cars, it would have lost more money.
Besides that, 19.83% of the participants said they would prefer Honda ATC and 16.95% wanted Nissan GT-R Skyline. The Smart Crossblade was the least popular option at 10%.
The Reason Why NYC Destroys Hundreds Of Dirt Bikes And ATVs Each Year
In 2021, eight people were killed by dirt bikes or ATVs, and the New York Police Department, along with then-Mayor Bill de Blasio, went on a crusade to get rid of illegal vehicles, according to The City. By the end of the year, the city had seized and subsequently destroyed approximately 500 bikes. As many as 3,000 were ultimately crushed under the tracked wheels of a bulldozer in 2021 (via The City).
When new Mayor Eric Adams took office on January 1, 2022, he continued the fight. By June, they had seized over 2,000 bikes — almost 80% over the number they took by that time the previous year. And there’s no sign of letting up, with the police nabbing more than 250 on a single Sunday in August.
The dirt bikes and ATVs are not street legal to begin with, lacking several required features like turn signals, brake lights, and mirrors. According to the New York Department of Motor Vehicles, any 1985 or newer motorcycle must be equipped with directional or turn signals that show amber to the front and red or amber to the rear. It must also have an adjustable rear view mirror, a red stop lamp on the back, and a headlamp on the front of the vehicle. None of these things are found on a vast majority of the illegal vehicles that, as Mayor Adams put it, are continuing to terrorize the city.
