Ultra-bright LEDs give us a glimpse of all that space junk orbiting Earth

SPACE WASTE LAB by Daan Roosegaarde [official movie]

Whether it’s electronic waste from old gadgets that are thrown into landfill sites or the enormous amounts of plastic in our oceans, there is a big problem with pollution on Earth. Unfortunately, the fact that this continues to be an issue, despite its visibility, shows how tougher it is to raise awareness. Imagine how much tougher it is, therefore, to make people aware of the pollution that they can’t see — such as the 29,000 pieces of human-made debris currently orbiting our planet. These rocket parts, non-functioning satellites and other pieces of space detritus pose a number of problems, including presenting a risk to orbiting spacecraft and satellites.

To help people realize just what an issue this is, Dutch artist Daan Roosegaarde has come up with an eye-catching, attention-grabbing installation. The so-called “Phase” project involves shining ultra-powerful LEDs into the sky to pinpoint the individual pieces of space junk as they whiz past Earth at speeds of up to 17,500 mph.

“The Space Waste Lab wants to upcycle the 8.1 million kilo of space waste currently in space,” Roosegaarde told Digital Trends. “Phase is the real-time visualizing of space waste above your head. We receive the tracking information of space agencies of 29,000 particles larger than 10 cm. Special software including safety aviation regulation guides the large LED lines, so the moment the two lines meet in the top, [we know] that is where the space waste is. It creates a mesmerizing experience, these huge lines of light scanning the universe for junk.”

Roosegaarde’s work only seeks to highlight the problem, not to remove the space junk, although this is something that other groups — including NASA — are actively trying to carry out. Once the waste has been removed, Roosegaarde told us that he believes it can be upcycled to create new products, such as 3D-printable materials.

The LED installation is currently being displayed in the Netherlands, where it will be viewable until January 19. It is accompanied by a dedicated lab space showing real space waste. After this, it will travel on to Luxembourg, and then on to the United States. Unless the problem has been sorted out by then, we guess!

This bizarre email flaw is leaking corporate secrets to anyone who buys the right domain
Security researchers discovered companies are accidentally sending sensitive emails to domains that outsiders can register.

You don't always need to hack into a company's systems to get its secrets. Sometimes, the company will simply email them to you. A new report by WIRED's Matt Burgess has uncovered a bizarre email security problem in which companies are inadvertently sending sensitive information to domains that can be registered and controlled by outsiders. Security researchers Cory Solovevich and Mike Sheward discovered that seemingly harmless addresses such as noreply and deleteduser can become unexpected gateways to corporate information when the domains behind them aren't properly controlled.

I found 3 ChatGPT features that turned out to be way more useful than I expected
ChatGPT on iPhone

I use ChatGPT pretty much every day, but somewhere along the way, I’ve also developed a habit of poking around and looking for features I haven’t tried yet. Some discoveries are genuinely useful, while others are the kind I’ll probably remember once every six months.

Every once in a while, though, I stumble across something that actually changes how I use ChatGPT. That happened recently with three features I’d somehow been overlooking. I’ve started using all three regularly now, and if you spend a lot of time in ChatGPT too, I think you’re missing out by not giving them a shot.

Anker just exposed a big problem with portable power stations
Appliance, Device, Electrical Device

When you're shopping for a portable power station, there's one number that's almost impossible to ignore: battery capacity. A 2 kWh battery should give you roughly 2 kWh of usable power, right? Unfortunately, things aren't quite that simple. Anker SOLIX has published new efficiency data for its S Series portable power stations, and it's putting the spotlight on something that doesn't get nearly as much attention as capacity: how much of the energy stored inside the battery actually makes it to your devices.

According to Anker, portable power stations are commonly advertised with efficiency figures measured under relatively heavy loads, where they can reach roughly 89% to 92% efficiency. But that's not necessarily how most people use one during an outage. Think about what you'd actually plug in. A Wi-Fi router might sip power continuously, a refrigerator switches its compressor on and off throughout the day, and a CPAP machine could run overnight. Together, those devices may draw just a fraction of what a large power station is capable of supplying. And that's where efficiency can start slipping.
