Researchers produce a map of the Milky Way’s star cemetery

The remains of huge stars that have later imploded into black holes and neutron stars have been mapped by researchers. According to the findings, close to one-third of the items in this “galactic graveyard” have been hurled out of the galaxy and it extends three times as high as the Milky Way.

According to a press release from David Sweeney, a PhD student at the Sydney Institute for Astronomy of the University of Sydney and the paper’s lead author published in Monthly Notices of the Royal Astronomical Society, “These compact remnants of dead stars show a fundamentally different distribution and structure to the visible galaxy.” “The Milky Way itself has a “height” of the galactic underworld that is over three times greater. Additionally, a startling 30% of items have been totally ejected from the galaxy, continued Sweeney.

When stars that are more than eight times bigger than our Sun run out of fuel and abruptly collapse, black holes and neutron stars are created. When this occurs, a chain reaction occurs that causes the star’s outer layers to explode as a supernova. Depending on its initial mass, the core continues to contract until it either collapses into a neutron star or a black hole.

Because the cores of neutron stars are so dense, neutrons are created when protons and electrons mix at the subatomic level. This reduces the overall mass of the object to a sphere “smaller than a city.” The star will continue to collapse if its initial mass is greater than 25 times that of the Sun until its core becomes so dense that even light cannot escape, forming a black hole. Due to their density, both types of stellar remnants distort the surrounding space, time, and matter.

To develop the first thorough map of the “galactic underworld” where these ancient star corpses are located, the researchers painstakingly recreated their whole lifecycle.

“Up until now, we had no notion where to look, which is one of the challenges in locating these antique artefacts. The oldest black holes and neutron stars were made when the galaxy was younger and had a different shape, and they underwent extensive modifications over billions of years. It has been a major task to model all of this to find them,” said Sydney Institute for Astronomy’s Professor Peter Tuthill in a press statement. Tuthill is a co-author of the paper.

The study’s authors claim that newly produced neutron stars and black holes continue to conform to our galaxy, giving astronomers a hint as to where to seek. The oldest black holes and neutron stars, however, are comparable to “ghosts still haunting a house demolished long ago.”

“Accounting for the ‘kicks’ they receive at the violent moments of their genesis was the hardest challenge I had to solve in tracking down their true distribution. As a result of the asymmetric nature of supernova explosions and the great velocity—up to millions of kilometres per hour—at which the remnants are ejected, every object is propelled in a different, random direction, Sweeney said.

The researchers had to delve far back into cosmic time and reconstruct how these dead stars behaved over billions of years in order to pinpoint their location. The researchers used the analogy that it was like a snooker table where you would be able to determine where a ball went based on how hard and how you hit it.

Researchers from the University of Sydney and Monash University worked together to create complex models that stored the locations of the stars’ births, deaths, and final dispersal as our galaxy expanded.

Power users occasionally prefer to start over when they acquire a new computer, so they follow the pro-gamers’ advice and reinstall Windows using a brand-new ISO image that comes straight from Microsoft and is free of bloatware and needlessly complex “driver management programs.” Up until recently, the new Snapdragon laptops’ more specialized version of Windows 11 didn’t support that.

The Windows 11 build on these new laptops is unusual because of the Arm64-based hardware, which differs from the typical x86 and x64 innards found in most laptops and desktops. Microsoft has finally released a disk image (or ISO file) for these devices after several months of waiting. To perform a direct reinstallation or make a bootable flash drive for a different device, you may now download it straight from Microsoft’s website. It is identical to the installation media utility that is currently available.

Be aware that there may be some glitches if you use this method for a fresh install. Compared to previous designs, the Snapdragon X system-on-a-chip has a lot fewer hardware variables, but because it’s so new, Windows Update might not include all the necessary components. You may need to use an Ethernet connection or the old-fashioned sneakernet to manually load drivers from another computer. You may also need to do some Googling to locate all the files you require for that.

According to reports, OPPO, a Chinese firm, is getting ready to introduce its Reno 13 series smartphones in its native nation this month. As per 91Mobiles, the OPPO Reno 13 and Reno 13 Pro models are anticipated to debut in China on November 25. The Indian launch is probably set for January 2025. The smartphone series that debuted in July of this year, the Reno 12 series, will be replaced by the Reno 13 series.

Information regarding the specifications of the new Reno 13 and Reno 13 Pro smartphones has leaked online, although the business has not yet confirmed the launch date. These are the specifics:

OPPO Reno 13 Series: Anticipations

It is anticipated that the OPPO Reno 13 Pro would have a 6.78-inch, quad-curved OLED screen with 1.5K resolution. In contrast, the slightly smaller 6.7-inch display with FHD+ resolution is found on the OPPO Reno 12 Pro. In China, the Pro model is probably going to be powered by the MediaTek Dimensity 8350 chipset, while in India, it might have a different processor. A 50MP primary camera, an 8MP ultrawide sensor, and a 50MP telephoto sensor with 3x optical zoom are anticipated to be included in the OPPO Reno 13 Pro’s photographic setup. Most likely, the front camera will include a 50MP sensor.

With a 5,900mAh battery as opposed to the 5,000mAh battery on the Reno 12 Pro, the Reno 13 Pro is anticipated to significantly increase battery capacity. Additionally, it is anticipated that the smartphone would support both 50W wireless and 80W wired charging. Additionally, an IP68/IP69 designation for water and dust protection could increase its durability.

Although the price of the smartphones in the Reno 13 series is not well known, it is anticipated to be similar to that of its predecessor. For comparison, the 12GB RAM + 256GB storage version of the OPPO Reno 12 Pro launched at Rs 36,999, while the 8GB RAM + 256GB storage version of the vanilla model cost Rs 32,999.

Apple has released Final Cut Pro 11, an AI-powered program

Published

Apple introduced Final Cut X thirteen years ago. Considering that the video-editing program marked its 25th birthday this April, that represents just over half of its lifetime. Some have questioned whether the corporation has discreetly withdrawn the offering due to its multiple lifetimes in the consumer software industry.

Final Cut Pro finally reaches level 11, after 13 years of waiting, and Apple is no longer playing around. On Wednesday, the program will be accessible for download. After a 90-day trial period, new users will need to pay $300 to buy Final Cut Pro 11 from the Mac App Store, while current users will receive it as a free update.

What specifically justified the much anticipated move to 11? AI is two letters. The business is using AI to power new features just weeks after releasing Apple Intelligence for iOS, iPadOS, and MacOS.

Magnetic Mask is at the top of the list because it makes it simple to crop objects and people out of videos without using a green screen.

According to Apple, “This powerful and precise automatic analysis provides additional flexibility to customize backgrounds and environments,” “Editors can also combine Magnetic Mask with color correction and video effects, allowing them to precisely control and stylize each project.”

Transcribe to Captions, which basically adds text to Final Cut’s timeline, is the second standout AI-based tool here. The company claims that its in-house large language model (LLM) powers that feature.

Apple’s problematic mixed-reality headset is the subject of this article’s other major headline. The most recent iPhones now have the capability to record Spatial Video, and Final Cut may be used to edit that footage. It is possible to add effects, color correct the video, and change the titles’ depth placement.

Apple is reportedly working on a more inexpensive variant, even though CEO Tim Cook has acknowledged that the $3,500 headgear isn’t the mainstream consumer product the company wanted. Along with the iPhone 15 Pro and all iPhone 16 models, the Vision Pro itself can record spatial video. Additionally, Canon just unveiled a new twin lens that works with R7 cameras.

Additionally, there are various time-saving features in the new Final Cut. For example, Magnetic Timeline allows you to swiftly rearrange clips while maintaining audio and video synchronization.

According to Apple, Final Cut Pro 11 was developed especially for the M-series of CPUs, which are its first-party silicon. This includes having more simultaneous 4K and 8K playback capabilities.

Apple claims that the M-series of chips, their first-party silicon, were the reason behind the creation of Final Cut Pro 11. This includes the capacity to play back several 4K and 8K ProRes video streams at once.

Final Cut Pro for iPad 2.1 is being released by Apple concurrently with the eagerly anticipated release of Pro 11. The brightness and color of the touched-based interface will be increased, and the workflow will be enhanced as well. Starting on Wednesday, current users can also obtain that for free.
