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 start 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.

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.

Dec. 21 is the official start of winter; however the darkest afternoon comes weeks before on Dec. 7 when the sun will set later, expanding the afternoon brightness by five minutes.

In a single second light could travel around the world almost 9 times at a speed of 186,282 miles per second. Satellite’s transmitting time beeps to your car’s GPS receiver and in a similar way that was how light was discovered.

Nighttime is now longer and with the artificial sky glow, the New York City and Los Angeles skies are now 40 times brighter than the natural background. Tune in as we hear what a natural sky consists of.

The transit of Mercury will take place Nov. 11 as the smallest, speediest planet partially eclipses the sun. Make sure you take a peek into the sky because this rarity won’t happen again until 2032.

William Herschel discovered Uranus a little over 200 years ago and it created a sensation that still has no equal. Uranus, the third largest planet is now at its closest and brightest of the year.

In primitive cultures, full moons were singled out from all other phases and awarded names, but only a few have survived. The only designations still popularly used today are the Hunters Moon coming up on Sunday, Oct. 13 and the Harvest Moon that appeared last month.

Our society revolves around personal responsibility. Everyone believes they have the power to control their own lives. But, surprisingly, this may be an illusion. Listen in as we speak of Benjamin Libet’s experiment that proved this theory true.

From the gaseous Ring Nebula now overhead to the beautiful Saturn system rising in the southeast, rings are a recurring celestial theme. Yet, nature lovers often miss the most spectacular examples, the bright beautiful halos that often encircle the moon and sun.

Tonight or the next clear night, look straight up at nightfall, around 8 PM.  Only one bright star hovers directly overhead, so you can't miss it. This is Vega.

The Harvest Moon is coming up on Friday the 14th and all across the country people think they know what it means.  Some assume it has no observational significance and that "Harvest Moon" is just another archaic name like April's "Grass moon." Others imagine just the opposite, that the Harvest Moon looks special in some way: bigger or redder or higher or - something.

Now that it's September, we've all noticed that daylight is shrinking. Meteorologists often recite the number of hours and minutes of sunshine each day and then say "It's a decrease of two minutes from yesterday." Yet tomorrow they might say there's only one minute of decrease, or a three minute decrease. Let's get to the bottom of this.

This week it's the birthday of 127 million people from around the world, making our planet's shared birthdays pretty common. If we take one complete revolution around the sun to constitute a birthday, then our planet has had 4.5 billion birthdays.

The vast majority of meteors strike our atmosphere at between 22 and 37 miles per second, but thankfully our atmosphere slows nearly all meteors. Meteroids weighing more than 10 tons are were things get dangerous because they retain a portion of their original space velocity and could hit the ground at 10,000 miles per hour.
