Are we alone? Citizen scientists discover two planets orbiting Sun-like star



One of the biggest questions in astronomy has been: Are we alone? While planet hunters continue to search for habitable zones in the system, another discovery is creating a buzz in the scientific community. Citizen scientists, part of the Planet Hunters TESS project, have discovered two exoplanets orbiting a Sun-like star.

The new discovery published in Notices of the Royal Astronomical Society lists over twelve citizen scientists, who participated in the project led by Nasa.

The star dubbed as HD 152843 is about 352 light-years away from Earth and is about a similar mass as the Sun, but about 1.5 times bigger and brighter. Orbiting this massive star are two exotic worlds and, whenever compared to our Sun, they exist in the orbit of Mercury.

Planet b is 3.4 times bigger than Earth but like the size of Neptune and orbits the star in 12 days. In the mean time, Planet c is at a farther distance and 5.8 times bigger than Earth, orbiting HD 152843 in about 19-35 days.

In the interim, to confirm the presence of two planets and the accuracy of the data, scientists used the High Accuracy Radial Velocity Planet Searcher for the Northern hemisphere (HARPS-N) telescope in Spain and the Extreme Precision Spectrometer at Lowell Observatory.

“We’re taking baby steps towards the direction of discovering an Earth-like planet and studying its atmosphere and continue to push the boundaries of what we can see,” lead author of the paper, Nora Eisner, a doctoral student in astrophysics at the University of Oxford said. She added that studying them together is interesting to constrain theories of how planets both form and advance over time.

Scientists are continuing observations to confirm the mass of these two planets and are hopeful that once the James Webb Telescope, liable to be launched later this year, begins operation they will actually want to peer deep and take a gander at what sorts of particles make up the atmosphere in this system.


Satellite pictures show underground offices at China’s impending high-altitude air terminal



Recent satellite pictures propose that the Chinese are developing secured underground offices at the air terminal in Tashkurgan. Still under development, the high-altitude air terminal is often touted as the future base for Chinese desires in Central Asia.

The proposed air terminal in Tashkurgan is in nearness to the borders of Tajikistan, Afghanistan and Pakistan-Occupied Kashmir (PoK). It was in 2015 that China’s civil avionics specialists initially revealed their arrangements to develop an air terminal at the high altitudes of the Pamir level.

Be that as it may, development at this site started only in April 2020. This was nearly 7 days before the main fight among Indian and Chinese armed forces in Ladakh’s Pangong Tso was reported in May 2020.

Analysis of high-resolution business satellite imagery, provided by space firm Planet Labs, affirms the probable double use nature of the impending air terminal.

“These secured underground offices affirm the Chinese goals in the region; the reasonable utilization of these offices isn’t clear at this stage however it will provide a degree of disguise and insurance to the Chinese tasks” Col Vinayak Bhat (Retd) said.

Alongside the underground offices, development on different parts of the air base is additionally apparent in the satellite pictures dated May 28, 2021. Blacktopping of the runways and development of the terminal area can unmistakably be found in the satellite pictures, alongside deployment of stone pulverizing machines, land moving gear and development trucks.

Attributable to its higher altitude, the 3,800 meter long runway in Tashkurgan is marginally longer than the Hotan air terminal.

Elon Musk requested Tim Cook to make him CEO from Apple, new book claims



As though Elon Musk isn’t running enough organizations, he once may have recommended taking over as CEO of America’s most significant business, Apple.

Five years prior, amidst manufacturing delays and different issues tormenting Tesla’s arranged Model 3 dispatch, Musk is said to have had a call with Tim Cook during which the Apple (AAPL) CEO proposed purchasing Tesla. Musk said he’d do it, yet on one condition: “I’m CEO.” It reportedly took Cook a second to realize Musk implied taking his work.

That is as per a Los Angeles Times review of “Strategic maneuver: Tesla, Elon Musk and the Bet of the Century,” a forthcoming book by Wall Street Journal reporter Tim Higgins, who covers Apple (AAPL), Tesla (TSLA) and other tech organizations. The review, distributed Friday, adds that Cook reportedly responded to Musk with a swearword and hung up the telephone.

For their part, Musk and Cook have denied truly speaking to each other.

In December, Musk revealed on Twitter that he had considered selling Tesla to Apple however said he never really conversed with Cook. Replying to a report about Apple’s arrangements to release a battery-powered, mass-market automobile, Musk said he reached out to Cook during the “most obscure days of the Model 3 program” about securing Tesla “for 1/10 of our current worth.”

“He refused to take the gathering,” Musk said.

Musk likewise denied that the cooperation described in the book occurred in a tweet on Friday, following the distribution of the book review.

“Cook and I have never spoken or kept in touch with one another ever,” Musk said, adding that he had once requested a gathering with Cook to examine Apple purchasing Tesla, yet that it didn’t occur and “there were no states of securing proposed at all.”

Higgins, the creator, responded to Musk’s Friday tweet saying the Tesla founder was offered “a lot of chances” to remark on the tale.

“This tale comes from Musk’s own record of the discussion, as indicated by individuals who heard the retelling at that point,” Higgins tweeted.

At the point when gotten some information about the book’s claims, Apple directed CNN Business to an April talk with Cook did with reporter Kara Swisher, who got some information about Musk saying he refused a gathering. “You know,” Cook responded, “I’ve never addressed Elon, in spite of the fact that I have great admiration and respect for the organization he’s constructed.”

Musk and Cook were captured sitting close to each other — with only Oracle (ORCL) CEO Safra Catz between them — in a gathering with former President Donald Trump in December 2016. It’s muddled if the two talked.

“Strategic maneuver” is set to be released on August 3

Israel’s NSO hinders some government customers from utilizing its spyware over abuse claims: Report



Israeli cybersecurity organization NSO Group, which is at the center of the Pegasus sneaking around embarrassment, has briefly impeded a few government customers around the world from utilizing its spyware innovation as the firm probes its alleged maltreatments, as per a US media report.

The alleged utilization of the Pegasus software to keep an eye on journalists, human rights defenders, government officials, and others in various nations, including India, triggered worries over issues relating to security.

The suspensions are in response to an investigation by the Pegasus Project, a consortium of media outlets that reported the organization’s Pegasus spyware was connected to hacks and expected observation.

“There is an investigation into certain customers. A portion of those customers have been briefly suspended,” National Public Radio (NPR) cited a source in the Israeli organization as saying.

The source, an organization worker, didn’t name or quantify the government agencies — or their nations — that NSO has recently suspended from utilizing its spyware, attesting that Israeli defense regulations forbid the organization from identifying its customers, the report by NPR, an independent, nonprofit media association, said.
