The young star system, HD 163296, contains three infant planets which are creating huge gas waterfalls in space.

In the game of cosmic hide-and-seek astronomers play with planets, it can be particularly difficult to locate the huge worlds in very bright, young star systems. These systems are surrounded by a disk full of gas and dust swirling around their star. If planets are forming in the disk, they’re obscured by the dust, so astronomers have to get creative and watch how the dust moves to predict where a planet might exist.Â
But there seems to be an even more obvious sign a planet may be lurking in the space mist: gigantic waterfalls of gas.
At least according to a new study published in Nature on Wednesday by a team of US researchers. Using the Atacama Large Millimeter/submillimeter Array (ALMA) in northern Chile to image the star HD 163296, which is considered young at about 4 million years old, the team closely watched how gas moved around its surrounding disk. Analyzing the flows, the astronomers found gas cascading from the upper reaches of the disk and flowing into gaps further out in space. In those gaps? Baby planets, first discovered a year ago by the very same team.

Confusing? OK, let’s talk about it… with food.
If you think of the gaseous disk as a stack of three pancakes, the middle pancake is the area in which baby planets are forming. Gas, like maple syrup, seems to be leaking from the upper pancake onto the middle one wherever that formation is occurring. The astronomers were able to detect this steady flow of gas for the very first time and believe protoplanets — young planets — are pushing the gas around in this way.
“The patterns of these gas flows are unique and it is very likely that they can only be caused by planets,” said Jaehan Bae, a co-author on the paper and astronomer at the Carnegie Institution for Science.
Bae used computer models of the disk to show how certain-sized planets would affect the gas flow. The models lined up with the observations from ALMA, helping confirm the theory three hidden, baby planets are forming in the system.
“Looking ahead, analyzing the movement of material in a disk around a young star could help us find exoplanets while they are still in their most-formative stages,” Bae said.Â
“This could really help us understand how the architecture of a planetary system comes to be and maybe even unlock mysteries about the evolution of our own Solar System.” Â
Pixel 5 announcement: How to watch Google’s Launch Night In event on Sept. 30 – CNET

Google is teasing 5G for its Pixel 5 and Pixel 4A 5G.
It’s been a busy month, and next on the agenda for virtual phone announcement events is Google with its Sept. 30 “Launch Night In.” Google previously unveiled the Pixel 4A budget phone in August, confirming on the same day the existence of its next flagship, the Pixel 5, and the upcoming Pixel 4A 5G, both of which will have support for 5G. The invitation for Google’s September event confirmed that “new Pixel phones” would be among the products unveiled, along with a new Chromecast and a new Nest-branded smart speaker.Read more: Pixel 4A officially has the best camera for the money

The Pixel 5, like Google’s previous flagship phones, has been poorly protected from leaks (or perhaps, as CNET’s Lynn La suspects, the leaks are part of an intentional strategy on Google’s part). We got a first look at the design of the Pixel 5 on Monday, when photos surfaced along with details about the new phone’s processor, display, cameras, battery life and more. Rumors suggest that Google’s next flagship will include a hole-punch camera, a fingerprint sensor on the back (unlike the Pixel 4, which swapped it for Face Unlock), wireless charging and no headphone jack. Not much is officially known about the Pixel 5, other than its support for 5G, but leaks suggest a price of 629 euros (roughly $735, £575 or AU$1,035), with color options reportedly including green and black. The phone’s on-sale and release dates are not yet known.An apparently leaked image of the Pixel 5.
Google’s new Chromecast streamer (code-named Sabrina) has also attracted a flurry of rumors. According to photo leaks, the device will come with a remote, a first for the Chromecast family.Google’s virtual Launch Night In event will take place on Wednesday, Sept. 30, streaming online at 11 a.m. PT (2 p.m. ET, 7 p.m. BST). The stream will likely be hosted on the company’s YouTube channel, but we’ll update this story when a link becomes available.

Britain is assessing the impact of the sale of chip designer Arm to US company Nvidia, including commitments to keep its head office and staff in Cambridge, Eastern England, digital minister Caroline Dinenage said.”We are currently working very hard to understand the full impact of this move and what potential impact it may have on the future, and from there we are able to consider what steps we may wish to take,” she told lawmakers early on Tuesday.Nvidia, the biggest US chip company by market capitalisation, has agreed to buy Arm from Japan’s SoftBank for $40 billion (roughly Rs. 2,93,572 crores).Dinenage said ministers would consider commitments made by SoftBank and Nvidia to maintain Arm as a successful British business “incredibly carefully”, and the government had already had discussions with the parties involved.The decision whether to intervene in the deal would be taken by the secretary of state for digital, culture, media and sport after considering the relevant information, she said.Arm, the leading tech company in Britain, lost its independence in 2016 when it was sold to SoftBank after the Japanese conglomerate pledged to retain the company’s headquarters in Cambridge, England, and increase jobs.Nvidia’s CEO Jensen Huang has made similar commitments.Arm’s energy-efficient architecture underpins processors made by Apple, Samsung, Qualcomm and others, making the technology ubiquitous in smartphones as well as present in a host of other devices.© Thomson Reuters 2020Are Apple Watch SE, iPad 8th Gen the Perfect ‘Affordable’ Products for India?
