Longest partial lunar eclipse of this century is almost here: How to watch

Earth’s shadow will cover most of the moon Nov. 18-19, and it will take its sweet timing doing it.

Celestial showtime is almost here. There’s a partial lunar eclipse on tap for Nov. 18-19 and it’s notable for how long it will last. The Earth’s shadow will largely block the sun’s light from reaching the moon, tinging our lunar neighbor with darkness.

NASA statistics on lunar eclipses from 2001 through 2100 show this month’s partial eclipse will be the longest of the century with a duration of over 3 hours and 28 minutes. Compare that with the longest total eclipse of the century, which happened in 2018 and stretched for nearly an hour and 43 minutes.

The Holcomb Observatory in Indiana shared a handy graphic showing what to expect from the eclipse, which will cover most of the moon. «This will also be the longest partial lunar eclipse in 580 years,» the observatory tweeted.

What a partial eclipse looks like

Lunar eclipses don’t have the same dramatic appearance as a solar eclipse where it looks like someone is carving a black hole out of the side of the sun.

During a lunar eclipse, the moon darkens and sometimes takes on a reddish color. For a partial eclipse, Earth’s shadow doesn’t completely cover the moon. Partial eclipses are still fantastic experiences.

«Partial lunar eclipses might not be quite as spectacular as total lunar eclipses — where the moon is completely covered in Earth’s shadow – but they occur more frequently,» NASA said in a skywatching update. «And that just means more opportunities to witness little changes in our solar system that sometimes occur right before our eyes.»

When to watch the lunar eclipse

The eclipse will be visible to a large area of the globe across the evening of Nov. 18 and into Nov. 19. Exact viewing times will depend on your location, but at least some of the eclipse will be visible in most of the Americas, Australia, and in parts of Europe and Asia. The US will be in a great position to catch the eclipse action.

Head over to Timeanddate.com and search for your location to get your times. If you want to watch the full process, you could be in for a long night. For example, the partial-eclipse phase will kick off at 12:18 a.m. MT on Nov. 19 for me in Albuquerque, New Mexico, and reach its maximum at about 2:02 a.m. I’ll probably aim to set an alarm for closer to maximum rather than stand out in the cold for hours.

How to watch the lunar eclipse from anywhere

You have online options for following the moon action. These video feeds are a good fallback if you encounter cloudy weather, or if you just don’t want to stay up late or get up early to watch the eclipse in person.

The Virtual Telescope Project will go live with coverage of the eclipse at 11 p.m. PT on Nov. 18 (7 a.m. UTC on Nov. 19). VTP is collaborating with astrophotographers from around the world along with offering live commentary from astrophysicist Gianluca Masi.

Timeanddate.com has arranged for its own livestream starting at 11 p.m. PT on Nov. 18.

Eclipses aren’t everyday occurrences on Earth, and they’re not always easily visible. While some viewers might have to contend with middle-of-the-night scheduling for this month’s celestial event, it’s worth taking a moment to marvel at how the moon, the sun and our planet are connected as residents of this solar system.

You Can Watch an Exclusive Avatar: Fire and Ash Scene on TikTok Right Now

Disney and TikTok partner on an immersive content hub for James Cameron’s latest movie about the alien Na’vi.

If you’re not quite ready to head to the theater to watch Avatar: Fire and Ash, an exclusive scene preview might sell you on the visual spectacle. As part of a new collaboration with the social media giant, Disney is posting snippets of its new movie to its TikTok account.

This scene isn’t part of any trailer and won’t be posted to other social media accounts, making TikTok the only place you can view it — unless you buy a movie ticket. A first look at the new movie’s scenes isn’t the only Avatar-related bonus on the social media platform right now, either. TikTok has partnered with the house of mouse to bring an entire «immersive content hub» to the app.

A special section of TikTok includes quizzes and educational videos that explore the alien world of Pandora shown off in the movies. On TikTok, you can take a personality quiz to find out what Na’vi clan you most closely align with and unlock a special profile picture border to use on your account.

Science and fiction blend together with a series of videos from real doctors who explain the basis for some of Avatar’s world-building. If you want to learn about exoplanets or how realistic the anatomy of the movie’s alien animals is, these videos will feed your brain while still providing entertainment value.

Perhaps the most enticing part of Disney’s latest social media collaboration is the opportunity for fans to win prizes and trips. TikTok creators who make edits with the #TikTokAvatarContest hashtag are entered into a competition to win Avatar merchandise. The biggest winners will be able to take a trip to visual effects studio Wētā Workshop in New Zealand or visit Avatar director James Cameron’s Lightstorm Entertainment Studio in Los Angeles.

Avatar: Fire and Ash is the third installment in director Cameron’s cinematic passion project. While the first Avatar movie was released in 2009, Cameron didn’t release another entry in the franchise until 2022. In total, there is a five-movie arc planned for the indigo alien Na’vi on the moon of Pandora.

The Avatar movies are known for pushing the boundaries of CGI visual effects in cinema. They are also historically big winners at the box office: the original Avatar is the highest-grossing film of all time, earning $2.9 billion across its theatrical releases. Its sequel, Avatar: The Way of Water, is the third-highest-grossing film of all time, trailing Avengers: Endgame. You can stream those movies on Disney Plus.

It remains to be seen whether Avatar: Fire and Ash will financially live up to its predecessors. The film currently has mixed reviews from critics on Rotten Tomatoes.

Brain-Inspired Algorithms Could Dramatically Cut AI Energy Use

A new study dives into a major redesign for AI architecture.

One major issue facing artificial intelligence is the interaction between a computer’s memory and its processing capabilities. When an algorithm is in operation, data flows rapidly between these two components. However, AI models rely on a vast amount of data, which creates a bottleneck.

A new study, published on Monday in the journal Frontiers in Science by Purdue University and the Georgia Institute of Technology, suggests a novel approach to building computer architecture for AI models using brain-inspired algorithms. The researchers say that creating algorithms in this manner could reduce the energy costs associated with AI models.

«Language processing models have grown 5,000-fold in size over the last four years,» Kaushik Roy, a Purdue University computer engineering professor and the study’s lead author, said in a statement. «This alarmingly rapid expansion makes it crucial that AI is as efficient as possible. That means fundamentally rethinking how computers are designed.»

Most computers today are modeled on an idea from 1945 called the von Neumann architecture, which separates processing and memory. This is where the slowdown occurs. As more people around the world utilize data-hungry AI models, the distinction between a computer’s processing and memory capacity could become a more significant issue.

Researchers at IBM called out this problem in a post earlier this year. The issue computer engineers are running up against is called the ‘memory wall.’

Breaking the memory wall

The memory wall refers to the disparity between memory and processing capabilities. Essentially, computer memory is struggling to keep up with processing speeds. This isn’t a new issue. A pair of researchers from the University of Virginia coined the term back in the 1990s.

But now that AI is prevalent, the memory wall issue is sucking up time and energy in the underlying computers that make AI models work. The paper’s researchers argue that we could try a new computer architecture that integrates memory and processing.

Inspired by how our brains function, the AI algorithms referred to in the paper are known as spiking neural networks. A common criticism of these algorithms in the past is that they can be slow and inaccurate. However, some computer scientists argue that these algorithms have shown significant improvement over the last few years.

The researchers suggest that AI models should utilize a concept related to SNNs, known as compute-in-memory. This concept is still relatively new in the field of AI.

«CIM offers a promising solution to the memory wall problem by integrating computing capabilities directly into the memory system,» the authors write in the paper’s abstract.

Medical devices, transportation, and drones are a few areas where researchers believe improvements could be made if computer processing and memory were integrated into a single system.

«AI is one of the most transformative technologies of the 21st century. However, to move it out of data centers and into the real world, we need to dramatically reduce its energy use,» Tanvi Sharma, co-author and researcher at Purdue University, said in a statement.

«With less data transfer and more efficient processing, AI can fit into small, affordable devices with batteries that last longer,» Sharma said.
