Kiss the Sky Tonight -- Month of February 2018

Kiss the Sky Tonight -- Month of February 2018
Welcome to the night sky report for February 2018 -- Your guide to the constellations, deep sky objects, planets, and celestial events that are observable during the month. The night sky is truly a celestial showcase, so get outside and explore its wonders from your own backyard.

The winter night sky, filled with brilliant stars, presents one of the best celestial views. Orion, the Great Hunter of Greek mythology, dominates the winter sky. This constellation is among the easiest to recognize. It is full of young stars, dying stars, and many nebulae.

Betelgeuse, one of Orion's shoulders, is a red super-giant star about 650 times bigger than the Sun. It shines with the brightness of tens of thousands of Suns. Betelgeuse is near the end of its life. With the fuel at the star's core practically depleted, the core has contracted and heated, causing the outer gaseous layers of the star to swell.

Rigel, one of Orion's knees, is a triple-star system made up of two smaller stars orbiting a blue super-giant. Rigel's blue super-giant star has a short lifespan. Blue super-giant stars are much hotter than our Sun and use up their fuel quickly.

Orion's Belt is easy to spot. It is made up of three stars, Alnitak, Alnilam, and Mintaka. From the left side of Orion's Belt, look down to the Great Orion Nebula. Although barely visible to the naked eye, it is the brightest diffuse gas cloud in the night sky. "Nebula" is Latin for cloud. A small telescope unveils the details and grandeur of the nebula. Embedded inside the Orion Nebula is the Trapezium, a group of hot young stars so brilliant they cause the surrounding gas to glow.

Canis Major, the Great Dog, is the faithful companion who follows in Orion's footsteps. Canis Major is dominated by the most brilliant star in the night sky, Sirius. Sirius is actually a double system, containing a bright star and a much smaller and fainter companion. It is a mere 8.6 light years away.

Scanning with binoculars just below Sirius will reveal a lovely cluster of stars called NGC 2287 - M41. It contains about 100 stars, including several red giants. Stars in clusters like M41 were born together and are all about the same age.

Jupiter rises shortly after midnight, soon followed by Mars. A small telescope will reveal the cloud bands of Jupiter, and the reddish hue of Mars.

On February 15th, the Moon passes across the upper part of the solar disk, producing a partial solar
eclipse. The eclipse will be visible only from southern South America and parts of Antarctica.

The night sky is always a celestial showcase. Explore its wonders from your own backyard.

The following Deep Sky Objects are found in constellations that peak during the month. Some can be viewed with a small telescope, but the majority will require a moderate to large telescope. The following is adapted from my personal viewing list: "The Guy Pirro 777 Best and Brightest Deep Sky Objects."
