Vice News releases body camera video that purports to show moments after officers raided Breonna Taylor’s apartment – CNN

(CNN)New body camera footage obtained by Vice News purportedly shows what happened on March 13 in the moments after Louisville Metro Police officers raided the home of Breonna Taylor, who was shot and killed.

One video shows an officer, which Vice News says appears to be former Detective Brett Hankison, entering Taylor’s apartment after the shootings and ask about shell casings that are on the floor. He’s soon told by another unidentified officer that he should “back out” until LMPD’s Public Integrity Unit arrives. Hankison’s attorney declined to comment on the video.
No officer who took part in the March 13 raid was charged for Taylor’s actual killing. A grand jury instead leveled three counts of felony wanton endangerment against Hankison, state Attorney General Daniel Cameron said last week. The counts pertain to Hankison allegedly firing blindly through a door and window, with bullets entering an adjacent apartment where a pregnant woman, a man and a child were home, according to the state attorney general.
Hankison pleaded not guilty to the charges on Monday.
In another video, which Vice News says was the moment Breonna Taylor’s boyfriend Kenneth Walker was arrested, an unidentified officer can be heard yelling instructions to “walk backwards” and to “place your hands in the air and get on your knees” as the officer threatens to let his service dog loose if Walker does not comply.
Walker’s attorney, Steve Romines, said he’s seen the footage as part of his representation to Walker and confirmed its accuracy.
Initially, a Jefferson County grand jury indicted Walker on charges of attempted murder of a police officer and assault. In May, Walker’s defense attorney, Rob Eggert, filed a motion to have the indictment dismissed, alleging the grand jury had been misled by prosecutors.
The charges were then dismissed by Thomas Wine, the Commonwealth’s Attorney for Jefferson County. He said he disagreed that grand jurors had been misled when Walker was indicted, but agreed that it was important for them to hear from Walker directly before deciding whether to indict. If, after further investigation, the case was brought back to the grand jury, Wine said, Walker would be given that opportunity.
Romines maintains that Walker did not shoot Sgt. Jonathan Mattingly in the thigh and that a ballistics report from the Kentucky State Police does not support the prosecution’s assertion that the one bullet Walker fired struck Mattingly.
“The ballistics subsequently came back from the Kentucky state police and determined that the shot that they claimed hit Officer Mattingly, they could not determine it was fired from (Walker’s) gun,” Romines told CNN’s Chris Cuomo on Friday.
Walker has filed a $10.5 million lawsuit alleging malicious prosecution, false arrest and assault. He was defending himself with a licensed firearm when plainclothes police “violently broke down the door,” he alleges. The lawsuit cites the “stand your ground” law.
There was no video or body camera footage of the officers as they attempted to execute the search warrant at Breonna Taylor’s home, Cameron said at a news conference last week in which he announced charges against Hankison. Cameron said that body camera footage begins at the point when area patrol officers arrived at the location.
The Louisville Metro Police Department issued a statement to CNN saying, “We have no comment on this matter. This file has not been released by the department at this time. Our internal review of this case is ongoing so it would not be appropriate to comment.”
Taylor’s family’s attorneys when asked about the videos say they are not authorized to comment on the confidential case files, which are under a protective order.
Sam Aguiar, Taylor’s family’s attorney, said in a press conference Friday that there are as many as 50 videos from LMPD body cameras taken from the night Taylor was killed.
To date, Louisville Metro police department and Kentucky state officials have maintained that police officers executing the late-night, no-knock warrant on March 13 were not wearing body cameras. The Louisville mayor’s office did not reply to a request for comment. The Kentucky attorney general’s office also did not return a request for comment.

Gigantic Camera Snaps First-Ever 3,200-Megapixel Digital Photos – Gizmodo

Scientists from the SLAC National Accelerator Laboratory have produced the world’s first 3,200-megapixel digital photos. The images were snapped by an oversized digital camera destined for the Vera C. Rubin Observatory in Chile, in what is an early demonstration of this facility’s tremendous potential.

A photograph containing 3.2 billion pixels is difficult to imagine. You would need 378 4K ultra-high definition televisions to display one at its full resolution, according to a SLAC press release.

Wow. Now imagine this power applied to astronomy. Happily, that’s exactly the plan, as the SUV-sized camera used to produce these images will eventually be installed on the Vera C. Rubin Observatory in Chile, which is likewise under construction.

Once Rubin is up and running (hopefully in the next year or two), the 3,200-megapixel digital camera, or more succinctly, the world’s first 3.2-gigapixel camera, will capture a succession of panoramic images of the entire southern sky, which it will do once every few days for 10 years. This project, known as the Legacy Survey of Space and Time (LSST), will track the motions of billions of stars and galaxies, while creating the world’s largest astronomical movie. This next-gen observatory is poised to shed new light on the formation of the universe, dark matter, and dark energy.

The new images, which can be seen here, were created as a test of the system’s newly completed focal plane, which serves as the “eye” of the camera. To take these photos, the team used a 150-micron pinhole to project images onto the focal plane. During tests, the SLAC researchers imaged various objects, including a head of romanesco—a type of broccoli with a highly detailed surface. Interestingly, the focal plane needs to be chilled in a cryostat chamber and brought down to -150 degrees Fahrenheit in order for it to work properly.

The focal plane, which measures more than 2 feet wide (0.6 meters), contains 189 individual sensors, or charge-coupled devices, each of which can capture 16-megapixel images. Each light-gathering pixel is 10 microns wide—tiny, yes, but 10 times larger than the pixels in a typical camera phone (for reference, the average human hair is 50 microns wide). The focal plane is also super flat, measuring around a tenth the width of a human hair, allowing for exceptionally crisp, sharp images. Multiple sets of nine charge-coupled devices were assembled into squares dubbed “rafts,” of which 21 were installed onto the focal plane, along with four specialty rafts used for structural purposes. This required six months of careful work, as the rafts, which cost $3 million each, are extremely fragile.

The camera’s focal plane is big enough to capture a portion of the sky about the size of 4src full moons, and its resolution is so high that a golf ball could be spotted from 15 miles away.

The specs on this digital camera are nothing short of remarkable. At 3,200-megapixels, it could resolve a golfball from 15 miles away (24 km), and its field of view is large enough to include 40 full Moons. It will be able to spot objects 100 million times dimmer than those visible to the unaided eye, which would be like seeing a candle from a few thousand miles away.

The SLAC researchers are planning to add the camera’s lens, shutter, and filter exchange system later this year. Once testing is complete, the device will be transported to Chile and installed on the Rubin observatory, which could happen as early as mid-2021. Should all go well, the LSST project will start in 2022 and run

3,200 megapixels! The camera heart of future Vera Rubin Observatory snaps record-breaking 1st photos –

The camera core for the future Vera C. Rubin Observatory has snapped its first test photos, setting a new world record for the largest single shot by a giant digital camera.

The imaging sensor array, which comprises the focal plane for Vera Rubin’s SUV-sized digital camera, snapped the 3,200-megapixel images during recent tests at the Department of Energy’s (DOE) SLAC National Accelerator Laboratory in California. (“SLAC” stands for “Stanford Linear Accelerator Center,” the facility’s original name.)

The photos are the largest single-shot pictures ever taken, SLAC officials said — so big that showing just one of them full-size would require 378 4K ultra-high-definition TVs. The resolution is so good that a golf ball would be visible from 15 miles (25 kilometers) away.

Vera Rubin: The astronomer who brought dark matter to light

The first images don’t show distant golf balls, however. The SLAC team that’s building Vera Rubin’s LSST (Legacy Survey of Space and Time) Camera focused on nearby objects, including a Romanesco broccoli, whose intricately textured surface allowed the sensors to strut their stuff.

“Taking these images is a major accomplishment,” SLAC scientist Aaron Roodman, who’s responsible for the assembly and testing of the LSST Camera, said in a statement. “With the tight specifications, we really pushed the limits of what’s possible to take advantage of every square millimeter of the focal plane and maximize the science we can do with it.”  

Like the imaging sensor in your cellphone camera, the LSST Camera’s focal plane converts light emitted or reflected by an object into electrical signals that generate a digital photo. But the LSST Camera’s imaging core is far larger, more complex and more capable than any consumer electronic product. 

The newly tested focal plane is more than 2 feet (0.6 meters) wide and harbors 189 individual sensors, or charge-coupled devices (CCDs). The CCDs and their associated electronics are housed in 21 separate “rafts,” subunits that are about 2 feet tall, weigh about 20 lbs. (9 kilograms) and cost up to $3 million apiece.

The rafts were built at the DOE’s Brookhaven National Laboratory in New York and then transported to SLAC. In January 2020, the SLAC team finished slotting the 21 sensor-bearing rafts, plus another four specialty rafts not used for imaging, into their assigned places in the focal-plane grid, an exacting and nerve-wracking process that took about six months.

The rafts are packed incredibly tightly to maximize the focal plane’s imaging area; the gap between CCDs on neighboring rafts is less than the width of five human hairs, SLAC officials said. And the sensors are fragile, cracking easily if they touch one another.

“The combination of high stakes and tight tolerances made this project very challenging,” SLAC mechanical engineer Hannah Pollek, a member of the sensor-integration team, said in the same statement. “But with a versatile team, we pretty much nailed it.”

The newly released images are part of extensive, ongoing tests designed to vet the focal plane, which has not yet been installed on the LSST Camera. That integration step will happen in the next few months, as will the addition of the camera’s lenses and other key components, if all goes according to plan.  

The camera should be ready for final testing by the middle of next year, SLAC officials said. It will then be shipped to the Chilean Andes, where the Vera C. Rubin Observatory is being built.

The observatory, previously known as the Large Synoptic Survey Telescope, will use its 27.6-foot-wide (8.4 m) mirror and 3.2-billion-pixel camera to conduct a landmark 10-year study of the cosmos — the Legacy Survey of Space and Time for which the camera is named. The camera will generate a panorama of the southern sky every few nights, amassing an astronomical treasure trove that will include imagery of about 20 billion different galaxies.

“These data will improve our knowledge of how galaxies have evolved over time and will let us test our models of dark matter and dark energy more deeply and precisely than ever,” Steven Ritz, project scientist for the LSST Camera at the University of California, Santa Cruz, said in the same statement. 

“The observatory will be a wonderful facility for a broad range of science — from detailed studies of our solar system to studies of faraway objects toward the edge of the visible universe,” Ritz said.

High-speed camera captures a fluid behaving like a solid – Engadget

By itself, the study revealed what was possible with the material. You could turn the friction (and thus the fluid state) “on and off like a switch” just by varying the pressure.

However, Swansea University also suggested this could have a significant impact on engineering going forward. Scientists are already hoping to use DST for soft body armor, dynamic speed bumps and other products that could change properties on demand. Don’t be surprised if high-speed cameras become a mainstay of some engineering teams as a result.

Caught on camera: Astronomers snap ‘space butterfly’ pic from thousands of light-years away – WJW FOX 8 News Cleveland


/ Updated:

This highly detailed image of the fantastic NGC 2899 planetary nebula was captured using the FORS instrument on ESO’s Very Large Telescope in northern Chile. This object has never before been imaged in such striking detail, with even the faint outer edges of the planetary nebula glowing over the background stars.

(CNN) — Thousands of light-years away, there’s a “space butterfly” colored with brilliant blues and clouds of purple and red. It’s an image we’ve never seen in this much detail before.

So named for its resemblance to the winged insect, the “butterfly” is actually a planetary nebula — a giant cloud of gas that forms around an ancient star that hasn’t yet exploded. The European Space Observatory’s (ESO) aptly named Very Large Telescope, stationed in host country Chile, recently captured a vibrant image of the interstellar object.

It’s known as NGC 2899 (NGC stands for New General Catalogue, which lists nebulae and other astral bodies like this one). It’s located somewhere between 3,000 and 6,500 light-years away from Earth in the constellation Vela, which is visible in the Southern Hemisphere.

This planetary nebula isn’t long for this universe. Ultraviolet radiation lights up the shells of gas surrounding the star and causes them to shine quite brightly, the ESO said — but only for a few thousand years before they break up. That’s a relatively short life span in astronomy.

The Very Large Telescope that captured the image is the “world’s most advanced optical instrument,” according to the ESO. With the accompanying interferometer, the tool can illuminate details 25 times finer than individual telescopes. And on its own, the telescope tucked in the Chilean mountains can see things more than 4 billion times fainter than what the human eye could see.

Watch a tiny camera show the world from a bug’s point of view – Science Magazine

By Meagan Cantwell

To save energy, many insects swivel their head—instead of their entire body—to scan the world around them. Researchers have now replicated this with a tiny camera with a one-of-a-kind arm they can maneuver from a smartphone. The total system weighs just 248 milligrams—less than a dollar bill.

When strapped onto a beetle’s back, the camera can stream video in close to real time. It can also pivot to provide a panoramic view from the beetle’s perspective (as seen in this video). What’s more, when the camera was mounted onto an insect-size robot, the bot used up to 84 times less energy by moving the arm of the camera instead of its entire body.

The technology is one of the smallest, self-powering vision systems to date, researchers report this month in Science Robotics. In the future, scientists could use these tiny cams to gain insight into the habits of insects outside the lab.
