Have you noticed that brilliant star in the western evening sky over the past few months? That “evening star” is Venus, Earth’s nearest planetary neighbor.

In July of this year NASA will be launching our next rover to Mars, currently known as Mars Rover 2020.

The night sky is mystical to many cultures. Untouchable, seen only part of the day, changing from month to month, yet it clearly has an impact on life on the earth in terms of agriculture, weather changes, and navigation.

  Ready or not, year 2020 is here with a host of new astronomy highlights.

Over the past year, how many questions did you ask that went unanswered?

A black hole is an object with such strong gravitational attraction that even light can not escape.

With the onset of autumn, the natural scenery changes. From the vibrant fall leaf change at Black Canyon National Park to the changing constellations up above, autumn brings new perspectives.  And, as night falls earlier and earlier, we are given an extended opportunity to appreciate these newly-risen constellations.

Most of us can probably recall the childhood tale of “Goldilocks and the Three Bears,” in which that finicky young girl insisted that her porridge be “not too hot, and not too cold, but just right.” As it turns out, Earth may be equally persnickety. At a distance of about 93 million miles from the sun, our planet falls within the bounds of what astronomers have nicknamed “The Goldilocks Zone.” This term identifies the orbit around a star that is “not too hot, and not too cold, but just right.”

September 23rd marks the first day of autumn, also called the autumnal equinox in the Northern Hemisphere.  The word equinox comes from the Latin words aequus, meaning equal, and nox, meaning night.

When hot summer days yield to cool, pleasant nights, late summer evenings provide some of the best opportunities for star gazing. The constellations of summer and early autumn contain some of the finest examples of the various types of astronomical objects.

In July,1969, NASA first landed men on the Moon, attaining humanity’s first ever visit to another world.

Globular star clusters form a huge halo around the Milky Way Galaxy. If we resided at the center of our Galaxy, we would see them in every direction. However, we reside not in the center, but more than half way to the edge. We therefore view them in the direction of the galactic center, which we see best in summer. They are almost totally absent in the winter sky.

Earlier this year we lost a space exploration giant. Or better yet, a small robot. On February 13, 2019 we said a final farewell to our good pal, the Mars Opportunity Rover. That day, NASA’s last attempt to reach the rover failed. Its mission finally ended. If it had a burial site, its epitaph may read something like “Opportunity Rover: Roll on Good Robot” or “Here lies Opportunity, a real life Wall-E.”

On June 13, 2010 a bright fireball streaked across the sky over Australia. Was this a meteor or an errant piece of space junk burning up in Earth’s atmosphere? Actually, none of the above. It was Japan’s Hayabusa space probe returning to Earth at 25,000 m.p.h., after visiting the asteroid Itokawa.

A few months ago, we toured the Galactic Menagerie in the sky.  Today, let’s take flight and do some birdwatching!

One of the mathematical outcomes of Albert Einstein’s Theory of General Relativity is that an object with sufficiently high density will have such strong gravity that nothing, not even light, can escape. This is a ‘black hole.’

If April showers bring May flowers, what do meteor showers bring?

Just over a century ago there were no electric lights and no light-pollution. For millennia, anyone looking into a nighttime sky would see the Moon, 5 planets, and stars – lots and lots of stars.

If you were asked to picture the most fascinating thing named Mercury, what would come to mind?

Year 2019 is in full swing and features some eye-catching astronomical events.

National Park Service

Over my ranger career, I’ve been posted at some of the most spectacular locations on the planet. Grand Teton, Zion, Everglades, Wind Cave, and the Black Canyon, conjure up images of grand landscapes, wildlife, and history. At each park, I’ve talked to visitors from Topeka, to Tacoma, to Tampa. As you might expect, they come with questions - "How deep is the canyon?" "What animals might I see?" and, of course, the ever urgent "WHERE IS THE RESTROOM?!"

Looking toward the eastern horizon on a cool, mid-November evening the Autumn constellations are on prominent display while those of Winter are just starting to rise, and the constellations of Summer are setting in the west. Almost due east is the bright star Capella, in the constellation Auriga. Between Auriga and the constellation Andromeda lies the constellation Perseus, known for the famous double cluster and Algol, the Demon star.

This may be a great year to see summertime meteors.

These days, most of us spend our evenings retreating to our favorite corners of the Internet. Our chosen cyber spaces are often unique, different from those of our family members, coworkers, and neighbors. Each of us jokes about distinct factions of pop culture. It’s easy to feel disconnected, like there are no unifying experiences left. And yet, if we crave connections and shared experiences, all we have to do is find a dark spot and tilt our heads to the sky.

According to National Geographic, ninety-nine percent of the population of the U.S. and Europe can’t see the Milky Way from their homes. That makes many of us here on the Western Slope very special!  Feels good to be part of the one percent, doesn’t it?

High in our winter evening sky you’ll find the 6th-brightest star, yellow-white Capella, along with other stars of the constellation Auriga.

It’s mid-February, and love is in the air. But for some constellations, it seems love can be blue.

With Winter fast approaching, with its long cold nights, the month of December may not seem to be an ideal time for star gazing. Fortunately, those willing to brave the cold will be amply rewarded by views of the most magnificent constellation in the sky, the brightest star, as well as a famous nebula.

Have you ever looked at a full or gibbous Moon through binoculars or a telescope? If so, you may have noticed some bright streaks that radiate outward from a few bright craters.
