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.

Why Is Pee Yellow?

WHY? is our attempt to answer all the questions every little kid asks. Do you have a question? Send it to why@mentalfloss.com.

Your body is kind of like a house. You bring things into your body by eating, drinking, and breathing. But just like the things we bring home to real houses, we don’t need every part of what we take in. So there are leftovers, or garbage. And if you let garbage sit around in your house or your body for too long, it gets gross and can make you sick. Your body takes out the garbage by peeing and pooping. These two things are part of your body’s excretory system (ECKS-krih-tore-eee SISS-tem), which is just a fancy way of saying “trash removal.” If your body is healthy, when you look in the toilet you should see brown poop and yellow pee.

Clear, light yellow pee is a sign that your excretory system and the rest of your body are working right. If your pee, or urine (YER-inn), is not see-through, that might mean you are sick. Dark yellow urine usually means that you aren’t drinking enough water. On the other hand, really pale or colorless pee can mean you might be drinking too much water! 

Your blood is filtered through two small organs called kidneys (KID-knees). Remember the garbage we talked about earlier? The chemicals called toxins (TOCK-sins) are like garbage in your blood. Your kidneys act like a net, catching the toxins and other leftovers and turning them into pee.

One part of your blood is called hemoglobin (HEE-moh-gloh-bin). This is what makes your blood red. Hemoglobin goes through a lot of changes as it passes through your body. When it reaches your kidneys, it turns yellow thanks to a chemical called urobilin (yer-ah-BY-lin). Urobilin is kind of like food coloring. The more water you add, the lighter it will be. That's why, if you see dark yellow pee in the toilet, it's time to ask your mom or dad for a cup of water.

Flashing Status Symbols Won’t Impress New Friends—and May Even Backfire

Trying to keep up with the Joneses isn’t a very effective way of making friends. As The Outline reports, a recent study in the journal Social Psychological and Personality Science suggests that flashing status symbols makes people less likely to want to be your friend.

While some may feel like sporting a luxury watch or designer clothes will draw people toward them, it actually does the opposite, making you a less attractive potential friend, according to a trio of researchers from Michigan, Singapore, and Israel. Over the course of six different experiments, the researchers found that study participants tended to think that high-status markers like fancy cars would help them make new friends. The trend stayed true across both participants recruited using Amazon Mechanical Turk and upscale shoppers stopped for a survey in a high-income suburb.

People thought that showing up to an outdoor wedding in a luxury car or going out to a downtown bar wearing a fancy brand-name watch would lead people to be more attracted to them as potential friends, compared to someone driving a basic car or wearing a generic watch. Yet participants also rated themselves as being more willing to befriend someone with generic clothes and cars than someone who flashed designer goods.

The paradox makes a little more sense if you go back to the idea of “keeping up” with our neighbors. People want to look high status in comparison to others. They don’t want to hang out with people who are flashing around luxury goods—they want to be the flashier ones.
