Confessions of a Heavy Thinker: 10:00 am on Thursdays, Angus Stocking

Confessions of a Heavy Thinker is a short feature created by Angus Stocking, whose intention is to loosen the listener's grip on fixed beliefs, so that more pleasant beliefs can be selected and implemented. In addition to Confessions, Angus also publishes essays on his blog, OtherBS.com, and has contributed essays to BoingBoing.net. His Kindle ebook, also titled Confessions of a Heavy Thinker, is available on Amazon for a very reasonable sum.

Western Slope Skies: Black Canyon Astronomical Society

Western Slope Skies is produced by members of the Black Canyon Astronomical Society, who take a look at our local night sky. Hear it every other Friday morning after the  local newscast (from 8-8:10 AM) and on the following Wednesday night at 8 PM during Global Express.

Pulse of the Planet: Weekdays at 1:00 pm

Each weekday, the Pulse of the Planet radio series provides its listeners with a two-minute sound portrait of Planet Earth, tracking the rhythms of nature, culture and science worldwide, blending interviews with extraordinary natural sound.

Hightower Radio Lowdown: Tuesday & Thursday at 7:00 pm

2-minute commentaries by Jim Hightower, America’s most popular populist. He is a best-selling author, public speaker, and political sparkplug who learned from his daddy, W. F. Hightower, that “Everybody does better when everybody does better.” Twice elected Texas Agriculture Commissioner (which put him square in the crosshairs of corporate agribusiness,) he has long chronicled the ongoing democratic struggles by America’s ordinary people against rule by its plutocratic elites.

Exciting research in the field of astronomy has been the search for exoplanets. An exoplanet is a planet that is orbiting a star other than our Sun.

A clear evening in late August offers much to contemplate, both near, relatively speaking astronomically, and far.

Today, I thought you might like to hear how any young person can get started on a career path to astronomy.

One year ago, NASA’s New Horizons spacecraft made its historic flyby of Pluto.

It’s a dark area broken by the faint glow of red lights, and your eyes are just adjusting to make out a figure, hunched over what vaguely looks to be a telescope.

“Hey, I’ve got Saturn!” exclaims the figure. “I’ve got a double star,” shouts another voice. “I’ve got the Andromeda galaxy. Come take a look!” says someone toward the back.

If you look to the east after sunset, you will notice a bright, reddish-orange object.  This is the planet Mars, 4th rock from the Sun.  Less than one month ago, Mars was at opposition.  This means that it is directly opposite from the Sun, as we view it.  This also means that it is very bright, because it is reflecting light directly back to us.  Opposition is the planetary equivalent of a full moon. 

The diameter of Mars is about 4200 miles, compared to Earth’s diameter of about 8,000 miles and its mass is just 11% of Earth’s.  On May 30, Mars was 47 million miles from Earth.

Imagine… You are on an exo-planet circling a star in the Hydra Galaxy Cluster.  Your powerful telescope zeroes in on a planet 150 million light-years away.  The planet is called Earth, but you won’t be seeing 2016 human inhabitants, you will be seeing images of dinosaurs… Images carried on light that left the Earth 150 million years ago.

You will be looking back in time.

The planet Mercury is the closest planet to our Sun.  Its average distance from the Sun is only 35 million miles. Mercury has the fastest orbital speed in the Solar System…88 days.  Perhaps this is why the planet is named after the speedy messenger to the Roman gods!

Comets are small, icy and rocky bodies that orbit the Sun. Many comets have highly elongated orbits that extend to the farthest reaches of our solar system, out to a sizeable fraction of the distances to the nearest stars. Out there, in what astronomers have termed the Oort Cloud, a vast collection of comets is thought to exist.

In late December the Sun follows a southerly path across our Western Slope skies, and daylight hours are short.   December 21 at 9:48 p.m.

A Primer on Meteor Showers

Typically, meteor showers occur when the Earth passes through particle clouds left by the passage of a comet.  The particles burn up in the Earth’s atmosphere, resulting in a brief streak of light.  The particles can range in size from dust to 33 feet in diameter.

The terms “meteor,” “meteoroid,” and “meteorite” are related, but are not identical terms.

Today I am going to discuss a few simple tips that will allow you to take pictures of the night sky.  These may not compare with professional images, but they will be YOUR images!

This is a continuing series on Women in Astronomy.  Today we meet Williamina Fleming.

It is easy to see that the sky above is blue. So why blue?  

If you rise early on these crisp October mornings, you may see an eye-catching planetary sight in our pre-dawn sky.

It’s that time of year again… Watching the leaves change color with cooling temperatures, warm apple cider, a pumpkin patch, light seems to slip away sooner.  What marks the fall season for you?

Black Canyon of the Gunnison National Park has long been known for some of the steepest cliffs, oldest rock, and craggiest spires in North America. The Gunnison River has sculpted this vertical wilderness of rock, water, and sky.  A grand piece of this wild landscape includes the pristine dark skies.

What is that brilliant light in the sky? If you are an early riser you may see a jewel in the east. Called the “morning star” as well as the “evening star” by cultures the world over, this light flickers a bit less than stars. It is not a star but the planet Venus. Had you looked about a month ago, Venus would have been the “evening star,” ripe for viewing by night owls. This planet is often referred to as our “sister” planet.

The summer night sky elicits an extra sparkle of excitement when we see the silvery, arcing band of the Milky Way, a beautiful cross-cut view of our home galaxy.

I remember being bundled in a blanket and being taken outside into the chill midnight air as a child. I would be sleepy and warm, held in my father’s arms. He would extend his arm and point, “look at the sky!”

By definition, Astronomy is a natural science which is the study of celestial objects.

It all started with humans looking at the night sky with just their eyes, and contemplating all those gleaming lights above them.

Today there is the Hubble Space Telescope which brings us brilliant photos of far off galaxies, space probes reaching out and sending back images of planets, asteroids and comets, and huge land based telescopes, that since Galileo’s time have grown from 1.5 centimeters, to 1 meter, to 10 meters in diameter.

On February 18th, 1930, a 24-year-old Kansas farmhand-turned-astronomer made a discovery that forever changed our understanding of the Solar System. On that evening, Clyde Tombaugh, who had grown up on family farms in Illinois and Kansas, discovered Pluto. Tombaugh’s discovery nearly doubled the size of the known solar system overnight.

Spring is quickly shifting into summer. For us at Black Canyon of the Gunnison National Park, this means that the busiest visitation days of the year are just around the corner. Folks from all over the world will soon fill the visitor center, planning adventures into the canyon and asking about park wildlife. Rangers will begin presenting geology walks along the rim and talks out at Chasm View. It’s an exciting time of year in the park.

The winter evening sky was dominated by two exceptionally bright “stars” that are actually planets — resplendent Venus, nearest of planetary neighbors, in the west, and regal Jupiter, largest of the planets, in the east. As we enter spring, Venus and Jupiter remain celestial highlights, and will treat us to a special double-feature in mid-April — each planet will be very close to a prominent open star cluster.

If you rise early on Saturday, April 4 you will be treated to an unusual event:  the third of four total lunar eclipses occurring within a period of just two years.  This has been called a lunar eclipse tetrad. 

Black Canyon of the Gunnison National Park, near Montrose, CO, is an excellent place to observe night skies free from light pollution. When it comes to constellations, one of the most famous is Ursa Major, meaning “The Big Bear,” which includes “The Big Dipper.”

2015 is a banner year for solar system exploration.  Although the European Venus Express Mission and NASA’s Messenger Mission to Mercury are ending, other missions will be gearing up in 2015.  NASA’s New Horizons probe will fly by Pluto in July, and in March, another NASA probe, called Dawn, will enter orbit around Ceres, the l

This is an ongoing series on Women in Astronomy.  Today, we meet three modern women in astronomy, Jocelyn Bell Burnell, Andrea Ghez, and Carolyn Porco.

The December solstice is coming!  At 4:03 p.m. Mountain Standard Time on December 21st, the Sun reaches its most distant point south in 2014, as viewed from Earth.  This defines the December solstice, which is the shortest day in the Northern Hemisphere and the longest day in the Southern Hemisphere.
