Saturn and Jupiter

As I wiped the sleep from my eyes a little before sunrise this morning, I gazed out my south-facing window and saw two bright objects in the sky. There was blazing beauty to each of them and together they took my breath away. I thought one was Sirius, until I did my research and realized…

TESS

If I were to go back to school to take more courses, I think I might take a few courses in orbital mathematics. The number of interesting orbits around masses in space has captured my imagination. Take for example the orbit of the latest NASA orbital space telescope, TESS (Transiting Exoplanet Survey Satellite). The following…

Cassini

Recently I wrote a sad lament for the Schiaparelli Lander, even as I praised those who had successfully inserted the Trace Gas Orbiter (TGO) into a near-perfect orbit around Mars. This orbiting communications relay and atmospheric laboratory will serve NASA scientists for the next several years and will eventually support a European Space Agency (ESA)…

Proxima b

There has been much speculation in recent days about the possible discovery of a habitable planet in the Proxima Centauri solar system. Just as our star, called the Sun, has a collection of planets in orbit around it, the closest star to our Sun may have planets in orbit around it. In the August…

Angels, Galaxies, and Pins

How many planets would fit into a Milky Way galaxy? This is certainly not a classic philosophical question like, “How many angels would fit on the head of a pin?” Yet, this question does have philosophical implications if you consider why planet hunters hunt planets. Some, certainly search for planets in our known galaxy because…

The Future of Space Exploration

Jupiter and Europa The 15th to 18th centuries were a time of unprecedented exploration of our world. Europeans, with a healthy sense of curiosity, and driven by a desire to conquer new worlds, were the primary instigators. Today, we live in a similar time of exploration as countries and private corporations turn their eyes to…

A Great Disturbance in the Force

There may actually be a ninth planet in our solar system after all. Astronomers at Caltech recently presented evidence for a large, gas-giant, planet in a 20,000 year orbit around our sun. They have been quoted as saying, “We have felt a great disturbance in the force.” This only adds to the crazy nature of…

“Yesterday I missed my exit, on my way to Sears” – Joe Diffie

Have you ever had one of those days where you missed your freeway exit and had to take an alternative route? The process can be quite time consuming and often adds several minutes to the anticipated travel time. It is hard not to get frustrated. Of course, such emotions only complicate things and make the…

The Dance of the Planets

(Photo credit: Universe Today) I have continued to enjoy the movements of Venus, Jupiter, and Mars. This particular conjunction of planets has now inspired my imagination for several weeks. Each morning I look to the east around five or six am to see if it is clear enough to see this amazing display. The relative…

Venus, Mars, Regulus, and Jupiter Are Alright Tonight

Starship 21ZNA9 A good friend of mine Studies the stars Venus and Mars Are alright tonight “Venus and Mars” lyrics by Paul McCartney and Linda McCartney; published by MPL Communications, Inc. This morning, as I went for my before-sunrise-run, I was greeted by three planets and a bright star, in the eastern sky. The four…
