Looking Up: Tilt The Season

Sep 17, 2018

This week on Looking Up we learn the astronomical reason for the seasonal changes.

I have breaking news from the world of astronomy. The Earth has seasons! Ok, so maybe you already knew that. But do you know why? Ok, you probably do. You know that the Earth is tilted off being straight up and down in space by about 23 ½ degrees. But do you know why? Well, it’s because, we think, not too long after the Earth was formed, it got smacked by a massive collision with a protoplanet perhaps the size of Mars that knocked our fair planet off vertical and into, well, having seasons.

Looking Up: Vanishing Point

Sometimes when a thing becomes hidden, something else is revealed. Hal reveals an upcoming occultation in this week's episode of Looking Up. 

One of the great things about astronomy is that there are so many different things you can look at. Some astronomers are fascinated with planets, while others study entire galaxies. And there are some dedicated amateur astronomers that are all about asteroids – those hunks of material left over from the formation of our solar system.

Looking Up: C'mon Back Neptune

When a planet appears to reverse course and move 'backwards' in the night sky it's said to be in retrograde motion. You may have heard about Mercury doing that but other planets do, as well. This week on Looking Up we learn of Neptune's impending retro action.

Lots of things are going retro – fashion, TV shows, and giant balls of gas. That last one refers to the giant gas planet Neptune, the most distant planet in the solar system.

Looking Up: Here Comes The Sun...

This week on Looking Up Bruce Bookout illuminates us on the historic and cultural aspects of that special star nearest to us.

The most obvious celestial object and most influential is the Sun.  Every ancient culture around the world saw the Sun as some form of deity. There are over a hundred difference names of the Sun, as either a god or goddess, in the various cultures of the world.  Consider how many song lyrics speak of the Sun.

Looking Up: One More Time...

On this week's Looking Up Hal points out the meteoric rise of GZ (short for comet Giacobini-Zinner) a celestial visitor visible in the Colorado sky this month.

Comets, you recall, are often called dirty snowballs in space. They are made up of the original materials from the formation of the solar system, and thus are some of the oldest things out there. Trillions of comets slowly circle the Sun way, way out there, many times farther than Pluto, in a cloud of comets known as the Oort Cloud. Some of these comets will never fall in toward the inner-solar system, and others will drop by and then zip away for thousands, or even millions of years.

Looking Up: A Big Baby Begs For Attention

When you're No. 2 you have to shine a little harder. This week on Looking Up we learn of the 2nd brightest,  but much lesser known star in the constellation Aquila.

If you’ve listened to Looking Up for the past three years or so, you may have noticed that sometimes I talk about really obvious things, like, say, the Moon or the Sun, or Jupiter or Saturn. And other times, I tell you about very obscure things that you likely have never heard of. I do the latter for two reasons. First, I think some of these lesser known things are really cool, and second, it gives you something to talk about at cocktail parties.

The Perseid Meteor Shower is back and the 2018 edition could be a banner event as we learn on Looking Up this week.

Looking Up: The God Of War Is Getting Rusty

This week Mars will be as big as the full moon (as long as it's viewed through a telescope at about 100x magnification).

There’s a rusty planet up on the Southern Colorado sky right now that is definitely worth taking a look at, because you’ll won’t see it this well again until 2035. I’m talking about Mars, and as it turns out, the orbits of Mars and the Earth are such that right now, Mars is about as close as it ever gets to Earth. In more “normal” years, so to speak, Mars is still a pretty thing in a telescope. With decent optics, you can make out the frozen pole and some dark places on the surface. With Mars so close, we should get even better views.

Looking Up: There May Be Snow On The Roof...

But there's still fire, or some mysterious heat source, deep in the belly of Pluto, as we learn on Looking Up this week.

OK, I admit it, I’m a sucker for Pluto. The diminutive dwarf planet has always fascinated me, and I still clearly remember a few years ago when I was able to actually observe the tiny speck of light that is Pluto through my own telescope.

This week on Looking Up Bruce Bookout takes time to explain calender reformation. 

We again mark a calendar to help us break up our revolution around the sun into smaller more manageable portions. Calendars are funny things in that keeping them and naming their parts lends to strange things. 

Looking Up: A Spot That's Hard To Spot

It's a good week to try and find the closest planet to our sun.

Often times, the brightest objects in the sky are our fellow planets. Jupiter, Saturn, and especially Venus blaze in the night sky. But the most elusive of all the planets to see might well be one that isn't farthest from the Sun, but rather is closest, the remarkable planet Mercury.

This week on Looking Up Bruce Bookout sheds some light and some shadow on the origins of the sundial.

As we have discussed before, timekeeping is an essential part of Astronomy.  The ancients relied on very low tech for many methods to tell time.  One effective method divides the day into relevant parts. Let’s shine a little light on the Sundial.

President Trump Monday announced his intention to create a "space force" that would oversee the military's activities off-world.

"When it comes to defending America, it is not enough to merely have an American presence in space," Trump said at a meeting of the National Space Council, which oversees the nation's space policy. "We must have American dominance in space. So important."

Looking Up: Miss Beehiven

This week on Looking Up Venus entertains the Beehive Cluster in a celestial gathering of lovely and luminous objects.

Have you been wondering what that really bright star-like thing is in the western sky after sundown? Well, it’s the planet Venus, the third brightest thing in our sky, after the Sun and the Moon.

This week on Looking Up we are introduced to Barnard's Star.

There is a lovely constellation in the Southern Colorado sky right now, with the awkward name of Ophiuchus. And in Ophiuchus is a remarkable star with the unusually possessive name of Barnard’s Star.

Secretary of the Air Force Heather Wilson is a 1982 graduate of the Air Force Academy. Now she's responsible for the more than 670,000 active-duty Air Force personnel and their families. She also oversees the military branch's more than $132 billion budget. Wilson was in town recently for the Air Force Academy graduation and the change in command at NORAD and NORTHCOM. While here, she sat down with 91.5 KRCC's Andrea Chalfin to talk about space.

Looking Up: Will Work For Helium

This week on Looking Up we comb through Leo the Lion's mane and discover a star by the name of Algenubi. 

We’ve talked before about constellations that really don’t look like what they’re named after, and some that do. The constellation Leo falls into that second group, as the bright star Regulus anchors the neck, so to speak, of the lion, with five stars above making what looks like a backwards question mark, or more correctly, the head and mane of the lion. And the very last star in that mane, out at the end, is the very cool star with a very long name, Al Ras Al Asad Al Janubiyyah, known today simply as Algenubi.

This week on Looking Up Bruce Bookout enlightens us as to what the study of archaeoastronomy actually is. 

One of the newer disciplines in science is the field of Archaeoastronomy.  We have been speaking to this subject during my tenure on “Looking Up”, but have never actually defined it. Archaeoastronomy is the study of astronomical practices, celestial lore, mythologies, religions and world-views of ancient cultures.  In many ways it is an “Anthropology of Astronomy”.

Looking Up: Big Little Ceres

This week on Looking Up we check in on one of our solar system neighbors... Ceres.

Can we talk Ceres for a minute? Or, more precisely, 90 seconds? You see, Ceres, the largest asteroid in the Solar System, is particularly well positioned to observe this week, and you should take a look – Ceres-ously!

Looking Up: In The Court Of The Planet King

This week on Looking Up we learn about the second biggest object in our solar system - Jupiter.

May is a great month in the southern Colorado sky if you like things that are really big. What's the biggest thing in our neck of the woods? I'll give you a hint, it's the Sun, which contains 99.98% of all the mass of the entire Solar System - planets, asteroids, comets, dust, the works.

Looking Up: Zub A Dub Dub, 3 Stars In A...

This week on Looking Up we learn about an interesting star system, and also how to pronounce Zubenelgenubi.

There is a very interesting star to see in the southern Colorado sky right now, and it’s pretty easy to find this month. Why? Because it has a giant ball of gas nearby as a marker. That’s right, the massive planet Jupiter, the brightest thing in our sky after the Moon and Venus is just below the difficult to pronounce star that is in the constellation of Libra.

On Looking Up this week, Bruce Bookout speaks about the mythical Thunderbird and the thunderous Navajo legend behind it. 

The mythology of the thunderbird is wide and various across America and Canada. Navajo legend holds that the Thunderbird carries all the clouds in its tail and rain under its wings. Thus when the Thunderbird constellation is shining brightly in the spring sky, the rainy season has arrived.

SpaceX has launched NASA's planet-hunting satellite TESS into outer space Wednesday evening from Cape Canaveral.

Tess — short for Transiting Exoplanet Survey Satellite — will spend two years searching for planets near bright, nearby stars. The satellite was launched on a SpaceX Falcon 9 rocket.

The launch window was narrow — just 30 seconds — and TESS was to be deployed into orbit about 48 minutes after launch.

The government could be heading into another shutdown Thursday, but some of the places deemed too essential to close are seldom heard of, like this windowless office in Boulder. 

It’s a weather prediction center, but not the usual kind. Instead of talking about snow or rain, these forecasters talk about plumes of molten plasma. The winds they watch travel at a million miles an hour. This office specializes in space weather.

Rocket Project to Launch in Pueblo

Jul 27, 2015

A testing and manufacturing center for rocket propulsion is launching in Pueblo.
 

The project from Centennial-based United Launch Alliance is for a next generation rocket called the Vulcan. The company is looking to commercialize space access and help make it more cost-efficient.

The facility will create 34 new jobs in Pueblo that are expected to generate around $19 million yearly in revenue for the local economy. 

Pueblo Economic Development Corporation President Jack Rink says the impact could be even bigger.
