The colors and light of the deep sea are on full display in these photos from The Radiant Sea: Color and Light in the Underwater World. In this dark realm, coral, shrimp, sharks, jellyfish squid, lantern fish, and more use multi-colored lights for self-defense, to lure food, communicate, and attract mates.

Here are just a few of the photos in the new book celebrating these diverse sea creatures. (Click to expand images to full screen.)

A Bay Area nonprofit is using the community land trust model to secure permanently affordable, community-owned housing and studios for artists. According to an article by Eliana Perozo in Next City, Artist Space Trust uses the same strategies as other land trusts to acquire properties that can be rented to people working in the arts industry at affordable rates.

In an interview with Next City, AST director Meg Shiffler said “We’ve accumulated $10 million in properties that have been bequeathed to us. Our model is built on mutual aid, not exclusively, but at the core of what we’re doing is building a portfolio through mutual aid.” All of the donors are artists themselves, says Shiffler, who were able to buy property at a time when it was much more affordable.

Despite the challenges of building capacity and finding funding, Shiffler says AST is growing and hopes to become a national model for community land trusts for creative workers. “I think we can become a powerful national advocacy and awareness group around artist housing. We have to prove that it’s successful and that we can change local policy here in California first.”

The U.S. Department of Transportation (DOT) announced it will reclaim management of Washington, D.C.’s Union Station, reports Rachel Treisman for NPR.

Although USDOT has owned the station since the 1980s, it has historically been managed by the Union Station Redevelopment Corporation, a local nonprofit founded in 1983. Amtrak took over operations last year.

Now, USDOT says “strong direction is needed to restore this federal asset to its former glory,” and D.C. Mayor Muriel Bowser noted that the station needs roughly $8 billion in repairs, which the District cannot afford. Bowser said shifting management is “step one,” but that “If it's about what Union Station needs for its total transformation, that would be an amazing initiative for the federal government to take on.” USDOT says it will “maximize the retail revenue of the station, the revenue of the station as an event space” to get the station on “stable financial footing” and “will address the building's infrastructure needs, which include improvements to its elevators, lighting and security, as well as ‘replacing the roof and other major systems.’”

Union Station serves about 70,000 passengers per day on over 200 daily trains, including Amtrak and regional commuter lines.

When you load up YouTube, you likely start watching videos rather than digging into the available settings and feature. But, there is one specific feature that’s worth knowing about, and that’s the option to set up multiple channels.

With a multi-channel setup, there’s no need to keep logging in and out: You just switch between them as needed, and each channel comes with its own viewing history, playlists, recommendations, and uploads.

Think of channels as distinct spaces where you can separate out your YouTube watching, uploading, or both. Maybe you want to have one channel for the kids, or one for your hobbies, or one for your side project livestreaming games. Whatever the reasons, these channels are simple to set up and manage.

The benefits of multiple YouTube channels

A new YouTube channel is like a fresh start with the video sharing platform: It’s a reset for your playlists, subscriptions, and recommendations. If you feel like your existing YouTube channel has got too cluttered—maybe with cat videos or AI slop—then a new channel might give you some room to breathe and start again.

Alternatively, maybe there’s some watching you want to do that won’t affect your main YouTube algorithm. Perhaps you crave a deep dive into French cinema, or long truck journeys. Maybe you want to enjoy hours-long lo-fi music mixes during the working day, without having them pop up in your recommendations the rest of the time.

A new channel also means a separate space for your uploads, which is the main reason the multiple channel feature exists. Whether you want to launch a video series on painting or hiking or anything else, you can do so without affecting your main channel or revealing your identity to the wider world. It’s a good way to experiment with ideas on YouTube.

It couldn’t be much easier to do—you can have up to 100 different YouTube channels connected to the same Google account—and while a brand new Google account gives you a lot of the same benefits, it comes with a lot of extra baggage attached (like a Gmail address) and a much longer setup process.

There’s another advantage to separate YouTube channels if you’re a subscriber to YouTube Premium as well: All of your benefits, including an ad-free experience and the ability to download videos, get carried over to your other channels. 

How to set up multiple YouTube channels

You can switch between multiple YouTube channels in the mobile apps for Android or iOS, but to create new channels you need to be on the YouTube website in a desktop browser. Click your account profile picture (top right), then choose Settings. On the next screen, pick Add or manage your channel(s).

Any channels you’ve already created are shown, together with your main channel. Click Create a channel to make a new one, then give it a name and a picture, and choose a handle—obviously it’ll need to be something unique that isn’t already taken on the platform. Click Create channel, and you’re done.

When the channel is created, you’ll be taken to the YouTube Studio, where you can click Customize channel to tweak settings such as the banner image for your profile, a public description of your channel, and the homepage layout. Click View channel if you want to see how your channel page looks to other people.

The YouTube Studio is the place to go for uploading new videos, configuring their different settings, and monitoring how much attention they’re getting. However, you don’t have to use new channels for creating and uploading content: They can simply be used for browsing YouTube as well. Click your new channel picture (top right), then choose YouTube to go to the main site.

At first there’ll be no recommendations, because YouTube doesn’t know anything about this new channel, but as you start searching for and watching content, the various screens will start to fill up. As with your main channel, you can get to your history, your playlists, your liked videos and every other part of YouTube from the menu on the left.

If you’re not in North America, this month’s full moon will make for pretty compelling viewing: the full moon coincides with another full lunar eclipse! Why yes, that means it is also a big ol’ blood moon! But even if your eyes are shielded from that particular piece of cosmic horror, September has a couple of other celestial tidbits to offer persistent stargazers.

September’s full moon is the Corn Moon, a quintessentially American name if there ever was one. But as it happens, the full moon also coincides with the second full lunar eclipse of 2025—which means that it’s also a blood moon due to its signature rosy hue! This leaves us with… a bloody corn moon? A corny blood moon? An ‘80s slasher moon? Whatever you want to call it, some 6.1 billion people in Asia and the western part of Australia are about to see a decidedly sanguine full moon.

Unfortunately, those of us in North America aren’t among them. Unlike March’s lunar eclipse , the moon will be below the horizon by the time it is plunged into shadow. We’ll just be left with the corn. Always with the corn. 

If you’re wondering exactly why a lunar eclipse turns the moon red, instead of hiding it completely, the short answer is that the earth’s atmosphere refracts light onto the moon’s surface. Long-wavelength red light gets refracted the most, so this rosy light hits the moon. The long answer awaits you here. And if you want to see the full moon in all its unstained glory, the indispensable Farmer’s Almanac informs us that our satellite will reach peak illumination at 2:09 p.m. ET on September 7.

Venus and Jupiter have been spending a lot of time together of late. Last month found them hanging out in the same part of the sky.The Goddess of Love clearly liked what she saw, because they’ll be spotted together again this month. 

The two planets will appear near each other low in the east-northest of the sky, with Jupiter rising first, between 1:30 a.m. and 3 a.m., and Venus following between 4:30 a.m. and 5:45 a.m. Chicago’s Adler Planetarium suggests that the best time to see just what they’re getting up to will be September 16, when they’ll have  a delicate crescent moon for company. 

You’re probably familiar with the summer solstice (the longest day of the year) and the winter equivalent (the shortest day). But there are also equinoxes that mark spring and autumn. On these days, night and day are of roughly the same length,hence the name “equinox.”, a sort of Latin portmanteau of the words for “equal” and “night”. The Northern Hemisphere’s autumnal equinox is the spring equinox in the Southern Hemisphere (or “vernal equinox,” to give it its proper name), and vice versa.

One such event is happening on September 22 at 2:19 p.m. ET. In the Northern Hemisphere, it’s the autumnal equinox. The event marks the start of fall from an astrological point of view. From here, the days will get progressively shorter until the winter solstice (but more darkness means more time for stargazing!). Officially, meteorological fall begins on September 1 every year, but where’s the fun in that?

Anyway, whenever you find yourself staring skywards in September, remember that you’ll get the best experience if you get away from any sources of light pollution—and you check out our stargazing tips before you head off into the night.

Until next month!

The smelly, gigantic blobs of brown seaweed that drift across the Atlantic Ocean every summer may not seem like a major threat at first glance. Yet, they are major players in Earth’s marine ecosystems. Once believed to be restricted to the nutrient-deprived Sargasso Sea off the United States’ eastern coast, marine biologists now better understand pelagic Sargassum for what it is—a fast growing organism found across a vast range of waters, with complex ramifications for its surroundings.

Sargassum is a genus of brown seaweed (and therefore an algae) abundantly found across many of the planet’s oceans. The leafy organism also features gas-filled sacs called pneumatocysts that allow it to float atop water as both a habitat and food source for multiple marine species. However, it quickly can become a nuisance once it washes up on coastal shores. As Sargassum rots, it releases noxious hydrogen sulfide gas which emits its trademark “rotten egg” smell. Although not dangerous in small amounts, exposure to enough of it can cause eyes, nose, and throat irritation.

To better contextualize and study the seaweed, researchers at Florida Atlantic University’s Harbor Branch Oceanographic Institute published a review of 40 years’ worth of data in the journal Harmful Algae that analyzes 40 years of pelagic Sargassum’s development, expansion, and environmental impacts. 

“Our review takes a deep dive into the changing story of sargassum– how it’s growing, what’s fueling that growth, and why we’re seeing such a dramatic increase in biomass across the North Atlantic,” FAU Harbor Branch oceanographer and study co-author Brian Lapointe said in a statement.

By better understanding its shifting nutrient composition (particularly its carbon, nitrogen, and phosphorus contents), Lapointe and colleagues hope to understand how the pungent algae changes over time amid its larger ecological context.

Researchers became particularly interested in the seaweed after the first appearance of the Great Atlantic Sargassum Belt in 2011. Stretching from the West African coast all the way to the Gulf of Mexico, the bloom has returned every year except for 2013. And with each reappearance, the Belt only grows larger. In May, it reached a new record biomass of 37.5 million tons, and this excludes the Sargasso Sea’s base biomass of around 7.3 million tons.

Part of Sargassum’s surprise entry onto the global stage appears to be based on initial faulty assumptions. According to the historical review, early oceanographers initially only tracked Sargasso Sea’s seaweed based on surface sightings due to the belief that it flourished in warm, clear, nutrient-lacking waters. By the mid-20th century, researchers realized the region was a “biological desert,” leading them to question Sargassum’s needs.

In recent years, advanced ocean circulation models, field studies, and satellite observations have helped clarify the situation. It now appears that Sargassum actually thrives in nutrient-rich coastal spaces like the western Gulf of Mexico. From there, it likely enters the open ocean through the Loop Current and Gulf Stream, where it eventually feeds into Sargasso seaweed.

But what’s causing the Great Atlantic Sargassum Belt’s exponential growth in recent years? In short, nitrogen. Between the 1980s and 2010s, Sargassum’s nitrogen content rose by more than 50 percent.

“These changes reflect a shift away from natural oceanic nutrient sources like upwelling and vertical mixing, and toward land-based inputs such as agricultural runoff, wastewater discharge and atmospheric deposition,” explained Lapointe.

As for how the Belt formed in the first place, experts now theorize that an extreme atmospheric event is to blame. Between 2009 and 2010, a negative phase of the North Atlantic Oscillation potentially sucked Sargassum southward out of the Sargasso Sea and into tropical Atlantic waters. Basically, extreme environmental occurrences coupled with extreme human influences are the likely culprits.

“The expansion of Sargassum isn’t just an ecological curiosity–it has real impacts on coastal communities. The massive blooms can clog beaches, affect fisheries and tourism, and pose health risks,” Lapointe said. “Understanding why Sargassum is growing so much is crucial for managing these impacts.”
