NASA administrator Bill Nelson said Wednesday the agency will reveal the “deepest image of our Universe that has ever been taken” on July 12, thanks to the newly operational James Webb Space Telescope.

“If you think about that, this is farther than humanity has ever looked before,” Nelson said during a press briefing at the Space Telescope Science Institute in Baltimore, the operations center for the $10 billion observatory that was launched in December last year and is now orbiting the Sun a million miles (1.5 million kilometers) away from Earth. 

A wonder of engineering, Webb is able to gaze further into the cosmos than any telescope before it, thanks to its enormous primary mirror and its instruments that focus on infrared, allowing it to peer through dust and gas.

“It’s going to explore objects in the solar system and atmospheres of exoplanets orbiting other stars, giving us clues as to whether potentially their atmospheres are similar to our own,” added Nelson, speaking via phone while isolating with Covid.

“It may answer some questions that we have: Where do we come from? What more is out there? Who are we? And of course, it’s going to answer some questions that we don’t even know what the questions are.” 

Webb’s infrared capabilities allow it to see deeper back in time to the Big Bang, which happened 13.8 billion years ago. 

Because the Universe is expanding, light from the earliest stars shifts from the ultraviolet and visible wavelengths it was emitted in, to longer infrared wavelengths — which Webb is equipped to detect at an unprecedented resolution.

At present, the earliest cosmological observations date to within 330 million years of the Big Bang, but with Webb’s capacities, astronomers believe they will easily break the record.

– 20 year life –

In more good news, NASA deputy administrator Pam Melroy revealed that, thanks to an efficient launch by NASA’s partner Arianespace, the telescope could stay operational for 20 years, double the lifespan that was originally envisaged.

“Not only will those 20 years allow us to go deeper into history, and time, but we will go deeper into science because we have the opportunity to learn and grow and make new observations,” she said.

NASA also intends to share Webb’s first spectroscopy of a faraway planet, known as an exoplanet, on July 12, said NASA’s top scientist Thomas Zurbuchen. 

Spectroscopy is a tool to analyze the chemical and molecular composition of distant objects and a planetary spectrum can help characterize its atmosphere and other properties such as whether it has water and what its ground is like.

“Right from the beginning, we’ll look at these worlds out there that keep us awake at night as we look into the starry sky and wonder as we’re looking out there, is there life elsewhere?” said Zurbuchen.

Nestor Espinoza, as STSI astronomer, told AFP that previous exoplanet spectroscopies carried out using existing instruments were very limited compared to what Webb could do.

“It’s like being in a room that is very dark and you only have a little pinhole you can look through,” he said, of current technology. Now, with Webb, “You’ve opened a huge window, you can see all the little details.”

Uber courts drivers by letting them pick rides

Uber drivers in the United States who had to accept ride requests before learning where they were headed will soon be seeing details of trips being sought along with the fares
Share this:

Uber on Friday said it will let drivers in the United States see trip details before deciding whether to accept them — a new feature long sought by drivers.

A common lament by drivers at the app-summoned ride platform has been that they have to accept a request before learning where trips will take them, or how profitable they will be.

“Our new trip request screen makes it easier for drivers to decide if a trip is worth their time and effort by providing all the details — including exactly how much they’ll earn and where they’re going — upfront,” chief executive Dara Khosrowshahi said in a blog post.

Revealing details only once a driver had accepted a trip was seen as a way to ensure riders would get picked up promptly, and not be snubbed because they were headed to locations deemed undesirable by drivers.

But Khosrowshahi said drivers have made it clear that they want more flexibility and choice.

Uber said the new feature, called Upfront Fares, was tested in several cities and was a success with drivers while resulting in shorter wait times for passengers.

The ride-sharing firm will also shift from sending drivers a single ride request at a time, to letting them pick from a list of detailed passenger requests in an area.

Uber is engaged in a long-term effort to prove that its business model is socially and economy viable.

The “gig economy” — which uses temporary independent contractors for short-term tasks — has grown rapidly since Uber’s launch in 2009 and is promoted as a flexible way for people to earn money without the constraints of a full-time job.

But there has been growing backlash in countries around the world about the conditions and dangers gig workers face.

Uber driver ranks — which shrank during the Covid-19 pandemic — have not rebounded as quickly as demand for rides, and soaring fuel costs have made the gigs less attractive.

The firm in March announced a surcharge on both rides and Uber Eats meal deliveries that would go directly to drivers to help offset high fuel prices.

Elon Musk fires back at Twitter in court battle

Court rules require Elon Musk to provide a public version of his 'confidential' counter claims against Twitter as the court battle over holding him to the terms of the $44 bn buyout deal heads for trial in October.

Elon Musk on Friday filed claims against Twitter as he fights back against the tech firm’s lawsuit demanding he be held to his $44 billion buyout deal.

Musk’s counter-suit was submitted along with a legal defense against Twitter’s claim that the billionaire is contractually bound to complete the deal he inked in April to buy Twitter, the Chancery Court in the state of Delaware said in a notice.

The 164-page filing was submitted as being “confidential,” meaning the documents were not accessible by the public, the notice indicated.

Rules of the court, however, require Musk to submit a public version of the filing with trade secrets or other sensitive information redacted.

A judge has ordered a five-day trial over Twitter’s lawsuit against Musk to begin on October 17.

The Tesla boss wooed Twitter’s board with a $54.20 per-share offer, but then in July announced he was “terminating” their agreement on accusations the firm misled him regarding its tally of fake and spam accounts.

Twitter, whose stock price closed at $41.61 on Friday, has stuck by its estimates regarding accounts run by software “bots” rather than people, and argued that Musk is contriving excuses to back out of the contract.

The social media platform has urged shareholders to endorse the deal, setting a vote on the merger for September 13.

“We are committed to closing the merger on the price and terms agreed upon with Mr. Musk,” Twitter chief executive Parag Agrawal and board chairman Bret Taylor said in a copy of a letter to investors.

Billions of dollars are at stake, but so is the future of Twitter, which Musk has said should allow any legal speech — an absolutist position that has sparked fears the network could be used to incite violence.

Musk, Twitter get Oct. 17 trial in buyout fight

Twitter is due to face off with Tesla boss Elon Musk on October 17 in the US state of Delaware in a buyout trial
Share this:

Twitter’s lawsuit to force Elon Musk to complete his $44 billion buyout bid is set to go to trial on October 17, a US judge has ordered, in a case with major stakes for both sides.

The trial is due to open in a court in the eastern state of Delaware and is set to last five days to decide whether Musk can walk away from the deal.

The Tesla boss wooed Twitter’s board with a $54.20 per-share offer, but then in July announced he was “terminating” their agreement on accusations the firm misled him regarding its tally of fake and spam accounts.

Twitter has countered by saying Musk already agreed to the deal and can’t back out now.

An order from the judge handling the case, Kathaleen McCormick, lays out an expedited schedule to resolve a fight that has left Twitter in limbo.

She reminds both sides that they “shall cooperate in good faith” on matters like handing over information to each other, a key topic that can result in delays. 

Billions of dollars are at stake, but so is the future of Twitter, which Musk has said should allow any legal speech — an absolutist position that has sparked fears the network could be used to incite violence.

Twitter blamed disappointing results last week on “headwinds,” including the uncertainty imposed on the company by Musk’s chaotic buyout bid.
