Look Up Tonight! Saturn Is Big and Bright, With Rings Tilted Our Way

Look up tonight, June 14, and overnight into the early morning hours of June 15, and you’ll be able to see Saturn looming luminously in the evening sky. Bring a telescope and you might even be able to see its rings.

Tonight, Saturn is “at opposition”—that is, as close to the Earth as it's going to get this year, and therefore big and bright. It's because our orbits: We are presently in alignment with the Sun, and between it and Saturn, so from our perspective, the disc of Saturn is in full illumination. Think of it as a “full Saturn,” with the same general idea at work as when we have a full Moon.

So what are you waiting for? You’re not going to live forever. Grab a telescope and a blanket and get to the countryside. The Roman god of agriculture and wealth awaits!

HOW DO I SEE IT?

When you look at Mars through a telescope, you’re looking for the ice caps. When you look at Jupiter, you’re looking for its moons and gorgeous stripes. When you look at our Moon, you want to see the craters, ridges, and mountains along the terminator (the line dividing light and dark during the moon’s phases). Saturn, of course, is all about the rings.

Here is the good news: Any telescope of reasonable power should be able to see Saturn’s rings. (That $30 novelty telescope you bought your kid for Christmas that’s collecting dust in a closet? If it has 25x magnification—and it probably does—and if the sky is clear and light pollution low and you know what you’re doing, you can use that.)

Here’s the bad news: Saturn is smaller than Jupiter and a lot farther away from the Earth. Right now, even as it nears opposition, it's nine astronomical units away. (An astronomical unit is the distance between the Sun and the Earth.) This means you should prepare yourself for something less spectacular than Cassini-generated images. It’s going to be small. It’s going to be fuzzy. But it will be recognizable as Saturn, and it's a good year to try to spot its rings.

A good view of the rings is not always a guarantee. Some years, the rings are edge-on when seen through a telescope, making them appear more as a single flat line bisecting the planet than as actual rings circling an alien world. (Without enough magnification, the rings might seem to vanish entirely.) Other years, the rings are “open,” Saturn’s pole tilting our way, and you get that wonderful Glamour Shots pose, the rings 45-degrees forward and giving the camera all it’s got. This is because of the planet's orbit and tilts.

Why is it so important for you to get out there and check out Saturn tonight? Because 2017 is a “wide open” year. You’re going to see it all, and with enough telescope, you’ll even be able to make out the gap between the rings and the planet. Saturn will first creep over the southeastern horizon just after 9:30 p.m. EDT on June 14, and will reach its highest point in the sky around 1:30 a.m. This is the best time for viewing: a high, bright Saturn, due south and with rings aplenty. If you’re setting an alarm, give yourself a lot of time to set up and for your eyes to adjust to the darkness. The usual conditions apply: You need a clear sky and no light pollution.

If the weather is bad tonight or you have unbreakable plans, take heart: Saturn will look virtually identical tomorrow night—so much so that beginning at 8 pm EDT on June 15, Slooh is hosting a livestream of the planet featuring views from telescopes and live commentary by astronomers.

SOON THE ONLY WAY TO SEE IT

After September 15, the only way anyone will be able to see Saturn’s rings is to use a telescope, whether of the backyard or the Hubble variety. That’s because NASA’s Cassini spacecraft, which first arrived in the Saturnian system on July 1, 2004, will finally arrive at the end of its mission on that day. Cassini’s grand finale will see the spacecraft plunge into the mysterious atmosphere of the gas giant, where it will disintegrate, though not before returning data revealing the nature of the planet’s magnetosphere and surface winds, and providing some idea of composition of its core.

Cassini is at present still orbiting Saturn, though you will not be able to see the spacecraft with your telescope tonight, even if you do have access to Hubble.

By this point, your eco-friendly pal probably has a reusable water bottle that accompanies them everywhere and some sturdy grocery totes that keep their plastic-bag count below par. Here are 10 other sustainable gift ideas that’ll help them in their conservation efforts.

1. Reusable Produce Bags; $13

No more staticky plastic bags.Naturally Sensible/Amazon

The complimentary plastic produce bags in grocery stores aren’t great, but neither is having all your spherical fruits and vegetables roll pell-mell down the checkout conveyor belt. Enter the perfect alternative: mesh bags that are nylon, lightweight, and even machine-washable.

Buy it: Amazon

2. Animal Tea Infusers; $16

Nothing like afternoon tea with your tiny animal friends.DecorChic/Amazon

Saying goodbye to disposable tea bags calls for a quality tea diffuser, and there’s really no reason why it shouldn’t be shaped like an adorable animal. This “ParTEA Pack” includes a hippo, platypus, otter, cat, and owl, which can all hang over the edge of a glass or mug. (In other words, you won’t have to fish them out with your fingers or dirty a spoon when your loose leaf is done steeping.)

Buy it: Amazon

3. Rocketbook Smart Notebook; $25

Typing your notes on a tablet or laptop might save trees, but it doesn’t quite capture the feeling of writing on paper with a regular pen. The Rocketbook, on the other hand, does. After you’re finished filling a page with sketches, musings, or whatever else, you scan it into the Rocketbook app with your smartphone, wipe it clean with the microfiber cloth, and start again. This one also comes with a compatible pen, but any PILOT FriXion pens will do.

Buy it: Amazon

4. Food Huggers; $13

"I'm a hugger!"Food Huggers/Amazon

It’s hard to compete with the convenience of plastic wrap or tin foil when it comes to covering the exposed end of a piece of produce or an open tin can—and keeping those leftovers in food storage containers can take up valuable space in the fridge. This set of five silicone Food Huggers stretch to fit over a wide range of circular goods, from a lidless jar to half a lemon.

Buy it: Amazon

5. Swiffer Mop Pads; $15

For floors that'll shine like the top of the Chrysler Building.Turbo Microfiber/Amazon

Swiffers may be much less unwieldy than regular mops, but the disposable pads present a problem to anyone who likes to keep their trash output to a minimum. These machine-washable pads fasten to the bottom of any Swiffer WetJet, and the thick microfiber will trap dirt and dust instead of pushing it into corners. Each pad lasts for at least 100 uses, so you’d be saving your eco-friendly friend quite a bit of money, too.

Buy it: Amazon

6. SodaStream for Sparkling Water; $69

A fondness for fizzy over flat water doesn’t have to mean buying it bottled. Not only does the SodaStream let you make seltzer at home, but it’s also small enough that it won’t take up too much precious counter space. SodaStream also sells flavor drops to give your home-brewed beverage even more flair—this pack from Amazon ($25) includes mango, orange, raspberry, lemon, and lime.

Buy it: Amazon

7. Washable Lint Roller; $13

There’s a good chance that anyone with a pet (or just an intense dislike for lint) has lint-rolled their way through countless sticky sheets. iLifeTech’s reusable roller boasts “the power of glue,” which doesn’t wear off even after you’ve washed it. Each one also comes with a 3-inch travel-sized version, so you can stay fuzz-free on the go.

Buy it: Amazon

8. Countertop Compost Bin; $23

Like a tiny Tin Man for your table.Epica/Amazon

Even if you keep a compost pile in your own backyard, it doesn’t make sense to dash outside every time you need to dump a food scrap. A countertop compost bin can come in handy, especially if it kills odors and blends in with your decor. This 1.3-gallon pail does both. It’s made of stainless steel—which matches just about everything—and contains an activated-charcoal filter that prevents rancid peels and juices from stinking up your kitchen.

Buy it: Amazon

9. Fabric-Softening Dryer Balls; $17

Also great for learning how to juggle without breaking anything.Smart Sheep

Nobody likes starchy, scratchy clothes, but some people might like blowing through bottles of fabric softener and boxes of dryer sheets even less. Smart Sheep is here to offer a solution: wool dryer balls. Not only do they last for more than 1000 loads, they also dry your laundry faster. And since they don’t contain any chemicals, fragrances, or synthetic materials, they’re a doubly great option for people with allergies and/or sensitive skin.

Buy it: Amazon

10. Rechargeable Batteries; $40

Say goodbye to loose batteries in your junk drawer.eneloop/Amazon

While plenty of devices are rechargeable themselves, others still require batteries to buzz, whir, and change the TV channel—so it’s good to have some rechargeable batteries on hand. In addition to AA batteries, AAA batteries, and a charger, this case from Panasonic comes with tiny canisters that function as C and D batteries when you slip the smaller batteries into them.

Scientists Come Closer to Understanding COVID-19 'Cytokine Storms'

Researchers are one step closer to understanding the mechanisms behind "cytokine storms," an immune system reaction that can cause severe COVID-19 symptoms in patients infected with the coronavirus. In a new paper published in the journal Cell, scientists from St. Jude Children's Research Hospital describe their identification of the specific cytokines, or small proteins, that are produced by the body in an effort to fight the virus but sometimes overreact and wind up causing damage, including inflammation, lung injury, and organ failure.

After examining the many different kinds of cytokines in the body, researchers determined that no single cytokine caused this inflammatory response. Instead, it appears to be a combination of two specific cytokines, dubbed tumor necrosis factor (TNF)-alpha and interferon (INF)-gamma, that work in collusion to cause inflammatory cell death.

By identifying these proteins as the culprit, researchers suggested that administering neutralizing antibodies and disrupting the protein pathways that promote cell death might present a new treatment method for COVID-19.

"Understanding the pathways and mechanism driving this inflammation is critical to develop effective treatment strategies," co-author Thirumala-Devi Kanneganti, vice chair of St. Jude's department of immunology, said in a press release. "This research provides that understanding. We also identified the specific cytokines that activate inflammatory cell death pathways and have considerable potential for treatment of COVID-19 and other highly fatal diseases, including sepsis."

Thus far, this theory has only been tested in mice, which received neutralizing antibodies and were protected from severe COVID-19 symptoms. But in isolating the exact cytokines involved, it will likely be easier to locate an effective treatment, either from an existing drug or one developed specifically for the task. In time, researchers hope clinical trials of select drugs can be another tool in the fight against the virus.
