NASA’s James Webb Space Telescope passes key optics tests

Astronomers can breathe a little easier. NASA has confirmed the James Webb Space Telescope has passed checks and tests verifying its optical performance following a “fine phasing” alignment on March 11th. There also aren’t any critical problems or detectable blockages. Optical systems are performing “at, or above, expectations,” NASA said.

The fine phasing corrected alignment errors by using optical elements inside the James Webb Space Telescope’s NIRCam science instrument. The mission team gauged the performance by aligning and focusing the telescope on a star. The technology is very sensitive — as you can see above, Webb captured galaxies and stars in the background despite the very bright star in the middle.

NASA expects to finish aligning the observatory across all instruments by early May or sooner. After that, the team will spend two months prepping the instruments for capturing and sharing the first practical images and data in the summer.

The milestones show not just that Webb survived the 930,000-mile journey to its observation point, but that the telescope’s novel segmented mirror design works as promised — particularly important given the $10 billion price tag, numerous delays and Hubble’s mounting problems. For the most part, scientists can now concentrate on how they’ll use Webb to study the early universe and other elusive aspects of the cosmos.

Sam Barlow’s Immortality trilogy hits Xbox and PC this summer

Immortality, the latest game from Her Story and Telling Lies creator Sam Barlow, is set to hit Xbox Series consoles, Game Pass and PC this summer. Like its predecessors, Immortality is shot in full-motion video and uses interactive cinematic scenes as a main mechanic. However, unlike the previous games, Immortality has a distinct horror vibe, not just psychological thrill.

The game is broken into three parts, each one a mysterious, unreleased movie starring the actress Marissa Marcel. Marcel disappeared after filming wrapped on these movies, and players have to investigate the lost footage to figure out what happened to her. The movies are Ambrosio (1968), Minsky (1970) and Two of Everything (1999).

Barlow revealed the Immortality trilogy back in 2020 and released a teaser in June 2021, though details about the game have remained scarce. Today’s new trailer, which debuted during the ID@Xbox showcase on Twitch, was the first real dive into the game — and it looks delicious.

Barlow brought on three screenwriters to help with the Immortality script, Allan Scott (Queen’s Gambit), Amelia Gray (Mr. Robot) and Barry Gifford (Lost Highway). It looks like the game will come to additional consoles down the line, as Barlow said on Twitter, “Other platforms to be announced.”

Netflix thought now would be a good time to resurface Zelensky’s sitcom

Before he gained widespread acclaim for his leadership of Ukraine following Russia’s invasion, president Volodymyr Zelensky was a famous actor and comedian. He starred in a satirical comedy series called Servant of the People, which is now once again available to view on Netflix in the US.

Zelensky played a teacher who is unexpectedly elected president of Ukraine after a video of him ranting about government corruption goes viral. As The New York Times notes, the series, which ran from 2015 to 2019, proved successful in Russia as well as Ukraine. The show has previously been on Netflix in the US, and the service suggested it was bringing Servant of the People back by popular demand.

It’s not surprising that subscribers are interested in watching the show that helped propel Zelensky to the presidency. It’ll be interesting to see if Netflix shares viewership figures in the coming weeks. 

Still, Netflix is touting the return of the show amid a conflict in Ukraine in which thousands of people have been killed. The number of refugees who have fled the country is in the millions, according to the United Nations.

Netflix is one of many companies that have cut ties with Russia over the last few weeks. Its streaming platform is no longer available there. It reportedly suspended production and content acquisitions in the country too.

Epson’s latest laser projector promises 4K 120Hz output for $3,999

Only a month after revealing the Pro Cinema LS12000 laser projector, Epson is bringing much of the same tech to a cheaper model. The Home Cinema LS11000 4K PRO-UHD also uses multi-array laser diodes as the light source (which Epson says will last for up to 20,000 hours), as well as pixel-shifting technology and a three-chip LCD system.

The company claims its precision shift glass plate can refract light accurately to deliver an “exceptionally sharp and clear picture” with a 3,840 x 2,160, 8.29 million-pixel image at a display size of up to 300 inches. It says the Epson Picture Processor can handle resolution enhancement, frame interpolation, color, contrast and HDR imagery in real time. The projector supports HDR10, HLG and HDR10+, though there’s no mention of Dolby Vision.

The LS11000 can output 4K images at 120 fps with input lag times below 20 milliseconds, according to Epson. That could make it a solid choice for large-display gaming, though the lag might not quite cut it for high-performance players who need to minimize input latency. There are two HDMI 2.1 ports on the rear, one of which has eARC/ARC and Dolby Atmos support.

At 2,500 lumens, the LS11000 isn’t quite as bright as the 2,700-lumen LS12000. It has a lower contrast ratio of 1,200,000:1 compared with the LS12000’s 2,500,000:1. For those key tradeoffs, you’ll save $1,000 by opting for the LS11000. Epson’s latest laser projector costs $3,999 and it will ship later this month.

Instacart lets you buy ingredients from TikTok recipes with a few taps

Ever see recipe on TikTok and wish you could quickly buy all the necessary ingredients online? You just might. Instacart has introduced “Shoppable Recipes” that help you snap up ingredients when you see a meal on TikTok and supporting websites. Tap a button and Instacart will both find the needed in-stock items as well as help you arrange delivery. You could spot a dinner idea in the afternoon and have everything you require by the evening without planning a trip to the grocery store.

Support for TikTok recipes is “gradually” rolling out to creators using the Jump feature. Web access will initially launch as part of a team-up with Hearst, which will provide shopping buttons on sites like Country Living and Good Housekeeping. More tie-ins will be announced later in the year, Instacart said.

The strategy isn’t subtle. Instacart is clearly hoping the added convenience will persuade you to choose its service over rivals like Uber. To some extent, this is also about extending the brand — the recipe buttons will serve as Instacart ads that might prove influential even if you aren’t keen on a given recipe.

Google Classroom will help teachers monitor progress with practice sets

Students using Google Classroom won’t have to wait until a test to know how well they understand a concept. Google has previewed an upcoming “practice sets” feature in Classroom that lets teachers gauge progress through automatically graded assignments. Pupils can see real-time feedback on their answers, and can ask for hints through explainers and videos. Teachers, meanwhile, will know which students are struggling with a given problem.

Google is currently testing Classroom practice sets with some schools, and plans a beta release sometime in the “coming months.” They’ll be available to both teachers using the Teaching and Learning Upgrade as well as schools using Google Workspace for Education Plus. The company is encouraging would-be early adopters to register their interest in joining the beta.

Classroom’s practice feature won’t always be useful. Not every exercise can fit into a web form, after all. When it is relevant, though, it could help teachers devote more attention to individual students or focus lesson time on concepts that stymie the class at large. Kids will ideally be well-prepared for tests, while educators can refine their courses.

Heliophysics pioneer Eugene Parker dies at 94

Dr. Eugene Parker, a pioneer in the field of heliophysics, has died at the age of 94. In the 1950s, Parker developed a theory that predicted solar winds. As NASA notes, Parker pushed the field forward throughout his career, “advancing ideas that addressed the fundamental questions about the workings of our Sun and stars throughout the universe.”

Heliophysics centers on the physics of the Sun and its impact on the Solar System. In 2018, NASA launched the Parker Solar Probe, the first spacecraft it named after a living person. The probe is tasked with observing the outer corona (or atmosphere) of the Sun to improve our understanding of solar winds and space weather. In December, it became the first spacecraft to enter the Sun’s upper atmosphere.

“Anyone who knew Dr. Parker, knew that he was a visionary. I was honored to stand with him at the launch of Parker Solar Probe and have loved getting to share with him all the exciting science results, seeing his face light up with every new image and data plot I showed him,” Nicola Fox, director of NASA’s heliophysics division, said. “I will sincerely miss his excitement and love for Parker Solar Probe. Even though Dr. Parker is no longer with us, his discoveries and legacy will live forever.”

iHeartRadio’s PodGuides tool curates podcasts to inspire your next trip

For many people, the first thing they do when they start planning a new trip is to seek inspiration in travel guides, blogs and documentaries. It’s safe to say a podcast probably isn’t top of mind when you start daydreaming about your next escape. But iHeartRadio wants to change that. It’s launching PodGuides, a platform that curates podcasts designed to inspire your next trip.

When you visit the PodGuides website, you’ll find a map with more than 70 destinations pinned to it. Click on one, and you’ll get a curated list of podcasts that highlight what you can see, eat and experience in the place you want to visit. Most destinations include about five to 10 episodes, with productions like Lost and Found and Where to Go featured frequently. You can also find podcasts organized by interests like photography, food and nature hikes. You can listen to all the episodes directly on the website.

PodGuides probably won’t replace a proper travel guide if you’re looking for something exhaustive, but it’s clear that’s not the platform’s goal. Instead, think of it as a complement to the resources you already turn to when wanderlust hits. And if nothing, it may help you discover a new podcast to listen to daily.
