Strange Universe

Sundays, 9:35 a.m.
  • Hosted by Bob Berman

Astronomer Bob Berman sheds light on the mysteries of space and time. Always fascinating and fun, Strange Universe will take you places you never knew existed. Learn why Betelgeuse sometimes goes weirdly dim and how after the totality in 2017 in places like Wyoming and the Carolinas, millions finally got to see a total solar eclipse.

The lowest full moon of 2020 happens during the opening minutes of Sunday, July 5th. This will be the most amber or honey-colored full moon of the year, especially when it rises, at sunset Saturday evening. This full moon may be the true origin of the word “honeymoon” -- since it is amber or honey-colored, thanks to its light shining through the maximum amount of thick horizon air, which reddens the sun and moon whenever they’re low. In actuality, the term "honeymoon" was first recorded in 1552. The idea back then was that a marriage is like the phases of the moon, with the full moon being analogous to a wedding; meaning, it's the happiest and "brightest" time in a relationship.

We’ve always noticed that winter is cloudy. But now we’ll experience the year's sunniest period in our region. We went from being 62% cloudy from November through April, to 63% clear now through October, so let’s focus on this relatively short blue sky period. It lets us enjoy stargazing and moon watching – with the very best time to view the moon happening this weekend, when the half-moon provides stunning contrasts on craters through even the smallest telescopes.

This is not just Father’s Day and the solstice weekend, but also the New Moon. It starts what astronomers call a new lunation – day zero of the lunar month. A new moon is utterly invisible because it displays only its dark side and also sits near the sun in the daytime sky, lost in glare. But in popular speech many define "new moon" as the skinny crescent, first seen two evenings later. Millions around the world will then look for the reappearance of the moon as a thin crescent.

Now that warm weather is here, we're leaving windows open, which brings up the topic of our planet’s atmosphere. 

The air is 78% nitrogen and 21% oxygen, which leaves just one percent for everything else. Very few know that this is almost entirely argon – an inert gas our body has no use for. 

More interesting is the air’s tiny bit of carbon dioxide, since climate change has made it into a villain.

Solar eclipse
A Owen

A total solar eclipse can make people weep, that's how awesome it is; but the total part is important. Only during a solar totality do pink flames leap from the sun's edge, and animals go crazy, and stars come out in the daytime. None of that happens during a partial solar eclipse, which can't even be safely observed without eye protection. So if you want to be swept away, it's totality or nothing.

This coming Wednesday, details gets skimpier, but the moon starts brightening explosively, doubling its brilliance in just two nights until we reach next Friday’s full phase. The nights are now warm, and the air scintillates with magic. If you own any old telescope, now is the time to check out the Moon.

Einstein believed in locality. That’s the common sense principle that an object is influenced only by its surroundings. A kind of supplementary principle is local realism -- that all objects have actual properties independent of any measurement of them. Tune in this week as we observe the reason why large objects like Saturn do dwell in specific places and have motion.

It’s common in journalism to present two sides to every story. So every bad news bulletin should have some good news. And this motif actually applies to the entire universe. Now in mid-May, for example, we’ve entered the three-week period when the dazzling Evening Star is largest and most interestingly crescent-shaped though binoculars and small telescopes. The bad news is that when this happens, it means Venus will disappear in less than a month.

The sun is getting high up and strong, yet we take it for granted. Not many regard it with primitive awe, or find it amazing that a ball of fire crosses the sky every day.

Gaze up at nightfall, around 8:30. There, in the last fading blushes of twilight, you’ll see Venus, which has dominated the West for months. It’s also called The Evening Star. Take it in, because big changes are starting to happen and you don’t want to miss the show.

This weekend, especially Sunday night, the dazzling evening star hovers near the crescent Moon. It’s a stunning sight, but there’s even more to it than meets the eye. If you point a small telescope or even binoculars at brilliant Venus, you’ll see that, it too, has a crescent shape.

After the Moon, Venus is the brightest thing in the night sky. Nothing else even comes close. No wonder civilizations through the ages worshiped it. These days most people seem unaware of our sister planet, the nearest celestial body after the Moon, which is also called The Evening Star. Right now, Venus has reached its greatest separation from the sun while standing high above where the sun set. These are rare, perfect conditions that make Venus appear as high up as is ever possible.

You’ve probably heard that the famous star Betelgeuse has gotten weirdly dim. In past autumn it faded and faded until it was no longer an eye-catching object in its constellation of Orion. Nobody quite knew what was going on or how long the dimming would last. Nobody had seen it this faint since 1941. Added to the fact that Betelgeuse is the type of supergiant that will eventually explode into a supernova, well, that made many folks nervous.

Who hasn’t heard of the Seven sisters – also known as the Pleiades?  It’s the most beautiful star cluster, and the most famous. It’s obvious to the naked eye and stunning through binoculars, and these nights it’s unusually easy to find.

A major display of the northern lights is unforgettable, and if you've ever seen an exploding meteor, you've never forgotten it. But one natural celestial sight tops all of those, a total solar eclipse. Not a lunar eclipse and certainly not a partial solar eclipse. After the totality in 2017 in places like Wyoming and the Carolinas, millions finally got to see one.

Follow Orion's belt downard to the left, it points to Sirius, the Dog Star, the brightest star in the night sky. Orbiting it every 50 years is a tiny star, and nothing about it is ordinary.

Spring, marked by the vernal equinox, will occur on March 19 in all U.S. time zones. This has not happened since spring 1896. Host Bob Berman covers leap years and why we have this early start to spring.

With the clocks now changing, it brings up the subject of time. The question of time's reality has boggled philosophers and scientists for centuries. We see two opposing views: Isaac Newton who recognized time as inherently real, and Immanuel Kant who claimed time is not an actual entity, but a framework devised by humans.

If you enjoy vocabulary items you'll probably get pleasure in the word subitize. Some elementary school teachers now use that concept. It's the ability to immediately perceive how many objects you're looking at without counting them. Those who know constellations also subitize as well. When we see Orion, the three belt stars are an obvious formation; we don't have to count one-two-three to determine if they are hidden behind a cloud.

The new moon, low in the West, is taking the shape of smile. Watch the western horizion at dusk the next several evenings, and if its clear, you'll spot that slender, smiling crescent.

Things in the night sky are radically changing their brightness. Of course, we all know that the moon alters its phase and its brightness, but the big inconstant headline maker these days is the famous star Betelgeuse because it’s dimmer than anyone has seen in a century.

Mercury has the most out of round orbit of any planet with its distance from the sun changing between 30 to 40 million miles. It also has no axial tilt and at its poles, half the sun’s disk is always below the horizon, so there’s permanent darkness inside every slight polar depression and crater.

Palindromes are everywhere and everyone enjoys them.   These oddities are found in time, on the calendar and even in our universe.

During day or night a warm breeze is heaven while a howling wind is the enemy. Moving air certainly influences our moods, but now in mid-winter, we get the greatest winds, on average. Listen in as Berman covers the windiest mountain in the northern hemisphere, right here in the U.S.

To the ancients the sun circled around us, an idea that was later proved false. In the 4th century Aristarchus of Samos, who was rumored heretical at the time, arrived at conclusions that proved opposite: the earth actually revolved around the sun. A lesson we took from these scientific theories? Always do our own homework before assuming anything to be true.

“If a tree falls in a forest and nobody is there, will it make a sound?” and "does a candle actually burn yellow?" On this episdoe we talk physics and how our mind may be playing tricks on us.

Now is the time of our darkest morning. Sunrise is now at its very latest of the entire year. If you’d like to do some stargazing, you don’t need to set the alarm for 4 a.m., like you would in the summer. Instead you can head out around 6:30 a.m. where the planets and Big Dipper parade overhead.

2020 will be a truly extraordinary year in the sky. It starts this winter and early spring with series of stunning conjunctions and starting in the summer, the giant planets Saturn and Jupiter will hover next to each other, slowly getting closer and closer.

This year’s brightest planet is Venus, visibly seen low in the southwest as soon as night falls. It gives off a strangely steady light that doesn’t twinkle like other starts. Although it looks point-like to the naked eye, it has a little size to it (as even binoculars reveal) and this makes it more immune to having its light bent one way and then another by different temperature air layers.

Heat is simply the motion of atoms. At 98.6 degrees, all of your body’s atoms are moving at about 1,000 mph. Even the coldest place on earth, the Antarctic, where they measured -129 degrees Fahrenheit in 1983, still has plenty of atomic motion. We will speak about what happens when atoms do stop at -459.67 degrees, absolute zero.
