The James Webb Telescope Just Zoomed In on A Hot, Haze-Free Exoplanet

Planet TOI-421b lacks the haze of other exoplanets, which means we’re able to get a surprisingly clear understanding of it.

The James Webb Space Telescope just zoomed in on the atmosphere of a planet discovered in 2020 — and now we have the clearest data ever about an exoplanet.

The awkwardly named Planet TOI-421b’s exoplanet status means that it doesn’t orbit our sun. (Exoplanets are defined as any planet beyond our solar system.)

Don’t expect to travel there any time soon. It’s 244 light-years away from the Earth — for comparison, the dwarf planet Pluto is only five and a half light-hours from us. The planet orbits a star that is similar to our sun. It is considered a sub-Neptune planet because it’s larger than Earth, but smaller than Neptune, which is four times larger than Earth.

The planet was discovered through astronomical transit, which means astronomers noticed that a star dimmed as TOI-421b passed it in orbit. This isn’t a heavenly body that a hobbyist can spot, but the best cameras out there can get you started with astrophotography.

The exoplanet was mapped by a team of astronomers from NASA, the European Space Agency and the Canadian Space Agency, who worked together to analyze the planet’s atmosphere using a form of study called spectroscopy. By parsing out light frequencies in a planet’s atmosphere, scientists can figure out what elements are present — and which ones are missing.

TOI-421b’s atmosphere is rich in hydrogen and contains signs of water vapor. But it doesn’t contain signs of methane, which leads to hazy atmospheric conditions.

Most sub-Neptune exoplanets have atmospheres shrouded in haze, which makes them difficult to image. TOI-421b was chosen for the project because the initial analysis led scientists to believe that the planet could be accurately and clearly pictured through spectroscopic imaging.

Is this planet a ‘unique snowflake’?

The team of astronomers published their findings in the Astrophysical Journal Letters, where all of the key data for the project is collected in one paper. You can read the full write-up here.

The spectroscopic images of TOI-421b are accessible in the results section of the paper, and they paint a picture of many of the exoplanet’s strange and exciting properties.

Other sub-Neptune worlds had atmospheres filled with heavy gases that indicated they were potentially mostly composed of water, but TOI-421b is composed of lightweight gases — much like the star it orbits.

This has raised questions about how different types of stars could potentially affect the atmospheres of their orbiting planets. In a statement to Mashable, Eliza Kempton, the lead investigator on the study, said it was something the astronomers would need to further explore.

«We can see if this planet just turned out to be kind of a unique snowflake, or is it emblematic of a class of planets that all have similar properties,» she said.

Save Up to $35 Off a Baseus Charging Station This July 4th and Stay Powered Up All Weekend

When USB ports aren’t enough, a Baseus charging station is what you need. Power all your gadgets with multiple well-spaced AC outlets and no clutter.

Keeping all your gear charged can be a job unto itself, and it gets more complicated when you have visitors. Whether you’re having guests this Fourth of July weekend or you just need a better charging solution for your family, a charging station could be the answer. But even the best charging stations can only share so many watts between devices, which is why the best charging stations from brands like Anker and Baseus not only feature multiple USB ports but also multiple AC outlets. AC outlets accommodate those few devices that still use proprietary chargers, and it lets you expand beyond the included 2-4 USB ports without sacrificing wattage when you need to top off everyone quickly before heading out.

The Fourth of July deals are bouncing into next week’s Amazon Prime Day to give us some of the best savings of the year a week early. Among the dozens of mobile accessories Baseus has on sale this holiday weekend is a trio of towers that can declutter your desk and keep everything you need ready and recharged. Available in 6-in-1, 7-in-1 for $65, and 10-in-1 varieties, these charging stations all offer two USB-C ports, at least one USB-A port and multiple AC outlets. Just note: You’ll need to clip the on-page coupon to get the lowest possible price.

For the best blend of power and ports, Baseus’ 100W 7-in-1 USB-C charging station can fast charge a laptop at 65W — full speed for all Chromebooks and many Windows laptops — while a phone and tablet each standard charge at 15W and still leave 5W for your smartwatch while your non-USB tech or your desk’s smart speaker can use the AC ports on both sides and the back of the tower. These towers are part power delivery chargers and part surge protectors with surge and lightning protection to keep your digital lifelines from frying should calamity strike.

The Baseus $35 10-in-1 desktop charging station model may sound like it’s the most powerful, but it only offers 35 watts to share between the two USB-C and USB-A ports, leaving the lion’s share of the station’s potential power to the six AC ports. This isn’t to say 35W between four ports is useless, but you’ll want to use those ports for lower-powered devices like recharging your smartwatch or wireless earbuds.

If you’re looking to charge multiple phones and tablets with those ports, you’re probably better off going with the 6-in-1 USB-C Charging Station at $50, which may only have three AC ports but features a retractable USB-C cable in addition to one standard USB-A and one USB-C port. Those three ports share 65W, meaning that you can charge both a phone and tablet at full speed rather than both getting middling speeds.

Why this deal matters

I use a 100W charging station like this at my desk and have another next to my couch for both me and my guests to keep our phones powered and ready. Being able to stick my 65W travel charger into one of the AC ports and fast charge four phones instead of two — well, one phone and my Chromebook — when I have people over and then swap it back to powering my oil diffuser or smart speaker once they’re gone is a godsend, and since the wall outlets are spread out across multiple sides of the tower instead of sandwiched next to each other in a line, I never have to worry about bulky plugs blocking out half my ports.

Because these charging stations double as surge protectors, you can also click their switch to power off and disconnect everything when severe weather comes, unlike standard charging stations you would have to unplug. Living in lightning capital of the U.S. makes this feature more important to me than most, but it can also be handy for parents wanting a one-click shut-off for all the kids’ consoles and computers.

We’re still days away from Prime Day, and deals like these will continue to drop through the next week, but these chargers are all within a few dollars of their lowest prices ever. We’ll watch for further price drops and competing deals throughout the holiday week, including Anker’s plethora of deals on chargers, speakers and smart home appliances.
