James Webb Telescope to release more breathtaking cosmic views

After unveiling the clearest view yet of the distant cosmos, the James Webb Space Telescope has more to come. 

The next wave of images on Tuesday will reveal details about the atmosphere of a faraway gas planet, a “stellar nursery” where stars form, a “quintet” of galaxies locked in a dance of close encounters, and the cloud of gas around a dying star.

They will be published starting from 10:30 am Eastern Time (1430 GMT), in an event live streamed from the NASA Goddard Space Flight Center, just outside Washington.

Targets include Carina Nebula, a stellar nursery, famous for its towering pillars that include “Mystic Mountain,” a three-light-year-tall cosmic pinnacle captured in an iconic image by Hubble.

Webb has also carried out a spectroscopy — an analysis of light that reveals detailed information — on a gas giant planet called WASP-96 b, which was discovered in 2014.

Nearly 1,150 light-years from Earth, WASP-96 b is about half the mass of Jupiter and zips around its star in just 3.4 days.

On Monday, Webb revealed the clearest image to date of the early universe, going back 13 billion years, NASA said Monday.

The stunning shot, released in a White House briefing by President Joe Biden, is overflowing with thousands of galaxies and features some of the faintest objects observed.

Known as Webb’s First Deep Field, it shows the galaxy cluster SMACS 0723, which acts as a gravitational lens, bending light from more distant galaxies behind it towards the observatory, in a cosmic magnification effect.

Launched in December 2021 from French Guiana on an Ariane 5 rocket, Webb is orbiting the Sun at a distance of a million miles (1.6 million kilometers) from Earth, in a region of space called the second Lagrange point.

Here, it remains in a fixed position relative to the Earth and Sun, with minimal fuel required for course corrections. 

A wonder of engineering, the total project cost is estimated at $10 billion, making it one of the most expensive scientific platforms ever built, comparable to the Large Hadron Collider at CERN.

Webb’s primary mirror is over 21 feet (6.5 meters) wide and is made up of 18 gold-coated mirror segments. Like a camera held in one’s hand, the structure must remain as stable as possible to achieve the best shots.

After the first images, astronomers around the globe will get shares of time on the telescope, with projects selected competitively through a process in which applicants and selectors don’t know each other’s identities, to minimize bias.

Thanks to an efficient launch, NASA estimates Webb has enough propellant for a 20-year life, as it works in concert with the Hubble and Spitzer space telescopes to answer fundamental questions about the cosmos.

Flight tracking exposure irks billionaires and baddies

How to upset Russian freight companies, Elon Musk, Chinese authorities and Kylie Jenner in one go? Track their jets.

How to upset Russian freight companies, Elon Musk, Chinese authorities and Kylie Jenner in one go? Track their jets.

Flight following websites and Twitter accounts offer real-time views of air traffic –- and sometimes major news like Nancy Pelosi’s Taiwan trip –- but that exposure draws pushback ranging from complaints to gear seizures.

Whether Russian air freight firms, Saudi Arabian plane owners or others, Dan Streufert said his group gets dozens of “requests” each year to stop posting aircrafts’ whereabouts.

“We have not removed anything so far. This is all public information. And I don’t want to be the arbiter of who’s right and who’s wrong,” added Streufert, founder of the US-based flight tracking site ADS-B Exchange.

Limits do apply in some cases, but groups that piece together the flight paths note that the core information source is legally available and open to anyone with the right gear.

US rules require planes in designated areas be equipped with ADS-B technology that broadcasts aircraft positions using signals that relatively simple equipment can pick up.

A service like Sweden-based Flightradar24 has 34,000, mostly volunteer-operated receivers around the world to pick up the signals, a key source of information that’s routed back to a central network and combined with data on flight schedules and aircraft information.

Figuring out or confirming to whom a plane actually belongs can require some sleuthing, said jet tracker Jack Sweeney, who filed a public records request with the US government that yielded a form bearing the signature of a particular plane’s owner: Tesla boss Elon Musk.

Sweeney has gotten quite a bit of attention with his Twitter account that tracks the movements of the billionaire’s plane and even rejected Musk’s offer of $5,000 to shut down @ElonJet, which has over 480,000 followers.

“There’s so much traction, I’m doing something right. The celebrity thing –- people like seeing what celebrities are doing, that and the whole emissions thing,” he told AFP, referring to concerns over the planes’ greenhouse gas impact.

“Putting it on Twitter makes it easier for people to access and understand,” Sweeney added.

– ‘We will track anything’ –

Another of Sweeney’s Twitter accounts, powered by data from ADS-B Exchange, showed in July that US model and celebrity Kylie Jenner’s plane took a flight in California that lasted just 17 minutes.

The internet was not pleased and she faced a torrent of criticism on social media over concerns about the message it sent regarding climate change.

“They tell us working class people to feel bad about our once a year flight to a much needed vacation while these celebs take private jets every other day as if it’s an Uber,” tweeted @juliphoria, in an example of the outrage.

Neither Sweeney nor Streufert evoked a distinct redline they were concerned could be crossed by publishing the flight data.

“We will track anything because honestly, if somebody really was a bad actor, and they wanted to know where this stuff is, you can build the electronics for $100 and just deploy receivers to pick up the same signals yourself,” said Streufert from ADS-B Exchange.

Sweeney said “the data is already out there. I’m just redistributing it.”

There is also money to be made, but it’s not clear how much –- Streufert acknowledged he makes a living but declined to provide specifics and Sweeney said his flight tracking work brought in about $100 a month. Flightradar24 didn’t provide its revenue.

The services’ information -– as recently shown by the hundreds of thousands watching whether Pelosi would defy China’s warnings –- has significant potential for impact far beyond embarrassment of celebrities or the rankling of billionaires.

For example, ADS-B Exchange’s data was cited in a non-profit group’s report alleging Europe’s border agency Frontex worked to prevent migrants from crossing the Mediterranean, while US media used it to show surveillance planes flew over racial justice protests in Washington in 2020.

In fact, dozens of US Congress members responded to the revelations by signing on to a letter urging the FBI and other government entities like the National Guard to “cease surveilling peaceful protests immediately and permanently.”

In some parts of the world, governments have made clear the technology and resulting information is not welcome.

Chinese state media reported in 2021 that the government had recently confiscated hundreds of receivers used in crowd-sourced flight tracking, citing the risk of “espionage.”

“In many cases, it’s authoritarian regimes that don’t like this exposure,” Streufert said.

American drugmaker Pfizer is close to a deal to purchase Global Blood Therapeutics, which manufactures a recently approved drug against sickle-cell anemia, for $5 billion, the Wall Street Journal has reported.

Pfizer, one of the top makers of Covid-19 vaccines, hopes to conclude talks with GBT within days, the newspaper said Friday, citing people close to the negotiations.

But it said other takeover candidates remain in the running.

GBT’s sickle-cell treatment, marketed as Oxbryta, was authorized for those over 12 years old in 2019 but gained federal approval in December for children aged four to 11. The blood disorder affects millions.

Sales of Oxbryta helped the laboratory generate first-quarter turnover of $55 million (up 41 percent), while the company registered a net loss of $81.4 million.

GBT, which is based in San Francisco, California, is to publish its second-quarter numbers on Monday.

Pfizer, for its part, saw its second-quarter turnover jump by 47 percent — to a record $27.74 billion — boosted by sales of its Covid vaccine and pills.

Its net profit soared by 78 percent, to $9.9 billion.

GBT shares on the New York Stock Exchange were up 33.03 percent at the close on Friday, at $63.84, for a market capitalization of more than $4 billion.

Pfizer shares slipped by 1.18 percent, to $49.27.

Amazon said it will buy iRobot for $61 per share along with acquiring the company's debt
Share this:

Amazon on Friday announced a $1.7 billion deal to buy the maker of robotic vacuum Roomba in a merger that would play into the tech giant’s artificial intelligence and smart home ambitions.

US-based iRobot is a global company that builds robots and “intelligent home” innovations, having introduced Roomba self-operating vacuums a decade ago, Amazon said in a release.

“Over many years, the iRobot team has proven its ability to reinvent how people clean with products that are incredibly practical and inventive,” said Amazon senior vice president of devices Dave Limp.

Amazon’s deal to buy iRobot for $61 per share along with acquiring the company’s debt is subject to approval of shareholders and regulators.

Colin Angle is to remain chief executive of iRobot after the purchase.

The acquisition “reinforces Amazon’s interest and market position in robotics and home automation, and underscores the strategic value of AI,” Baird analyst Colin Sebastian said in a note to investors.

The Massachusetts-based company has a 30-year track record in robotics, and underlying software such as mapping and navigation, Sebastian said.

Amazon has been investing in smart home and automation technologies with acquisitions such as Ring doorbells, Kiva warehouse robots and self-driving startup Zoox.

“With Alexa and Amazon.com at the core, Amazon continues to prioritize opportunities to develop the smart home,” Sebastian said.

“MGM even fits as it powers more Prime Video on home entertainment devices.”

Amazon earlier this year closed an $8.45 billion deal to buy the storied MGM studios, boosting its streaming ambitions with a catalog including the James Bond and Rocky film franchises.
