Passing close to the "W" of Cassiopeia this week is the little green fuzz ball called Comet Jacques. Discovered last March 13, Comet Jacques is due to pass a safe 52.4 million miles from Earth on Thursday.
Scutum is an obscure little constellation, to be sure, with no star brighter than fourth magnitude and ranking only fourth in size among all the constellations. Even so, it is an easy constellation to find in the summer sky.
When Venus meets Jupiter Monday morning, they will appear a mere 1/3 degrees apart, less than the width of a single full moon.
Instead of writing about the upcoming Perseid meteor shower, I'll tell you about that big, bright, full moon that will be drowning out the meteor shower. The second full moon of summer is sometimes called the Green Corn moon. It so happens that this year’s Green Corn moon will also be a so-called “super moon.”
Rasalgethi (pronounced ras-al-geth’-ee) is a remarkable star. It is one of the reddest stars visible to the unaided eye and, with its faint emerald green companion star, makes for a wondrous sight through a telescope.
When the last rays of the summer sun fade from the evening sky, the misty star clouds of the Milky Way come into view, arching high overhead like a colorless rainbow.
If the night sky is dark and clear, you also can detect a network of dark clouds and tendrils meandering through the bright star clouds of the Milky Way. These dark patches are vast interstellar dust clouds thousands of light years away that gather in the space between the stars and effectively obscure the light of the distant stars behind them.
Warm summer nights are the perfect time to wander out under the starry sky and enjoy the other half of nature up over our heads.
Earth is farthest from the sun in early July each year, as the northern hemisphere is sweltering in the summer heat. This point in Earth’s orbit is called aphelion and literally means “farthest from the sun.”
If you wanted to attend the Stagecoach Star Party but were unable to for whatever reason, I have some good news. This coming Saturday evening, I will be conducting a second summer stargazing event out at the Yampa River State Park campground
You are invited to join other astronomy enthusiasts from around the community for the “Stagecoach Star Party” this Friday at the Morrison Cove Boat Ramp on the Southshore side of Stagecoach State Park beginning at 9:30 p.m., weather permitting.
To locate Corona Borealis, look high up in the eastern sky after darkness falls for a small half-circle of stars, like a letter ”C.” It’s about a third of the way from the bright star Arcturus toward the comparably bright star Vega to the east.
You can spot the gigantic house-shaped outline of the constellation of Ophiuchus high in the southeastern sky around 11 p.m. in early June. Look for him holding onto his pet serpent just above the fishhook-shaped pattern of Scorpius the Scorpion.
If you have good vision, you can make out an eighth star in the Big Dipper, right beside Mizar, the star at the crook in the Dipper’s handle. This little star is Alcor. Mizar and Alcor have been known since antiquity as the “Horse and Rider.”
This coming Friday night and Saturday morning, if astronomers’ calculations are correct, we might be treated to a brand-new meteor shower, possibly even a meteor storm.
