Kiss the Sky Tonight -- Month of February 2019

Posted by Guy Pirro   01/29/2019 02:18AM

Kiss the Sky Tonight -- Month of February 2019

The Great Orion Nebula (NGC 1976) is cataloged as M42 -- Few astronomical sights excite the imagination like the nearby stellar nursery known as the Orion Nebula. The Nebula's glowing gas surrounds hot young stars at the edge of an immense interstellar molecular cloud. Many of the filamentary structures visible in the featured image are actually shock waves - fronts where fast moving material encounters slow moving gas. The Orion Nebula spans about 40 light years and is located about 1500 light years away in the same spiral arm of our Galaxy as the Sun. The Great Nebula in Orion can be found with the unaided eye just below and to the left of the easily identifiable belt of three stars in the popular constellation Orion. The whole Orion Nebula cloud complex, which includes the Horsehead Nebula (IC 434), will slowly disperse over the next 100,000 years. This stunning Hubble image offers the sharpest view of the Orion Nebula ever obtained. Created using 520 different Hubble exposures taken in multiple wavelengths of light, this mosaic contains over one billion pixels. Hubble imaged most of the nebula, but ground-based images were used to fill in the gaps in its observations. The orange color in the image can be attributed to hydrogen, green represents oxygen, and the red represents both sulfur and observations made in infrared light.

Kiss the Sky Tonight -- Month of February 2019

Welcome to the night sky report for February 2019 -- Your guide to the constellations, deep sky objects, planets, and celestial events that are observable during the month. In February, the Winter Triangle is your guide to the night sky. The northern hemisphere is treated to views of the stars Procyon, Sirius, and Betelgeuse. Keep watching for the awe-inspiring views of the Orion Nebula, which is sculpted by the stellar winds of central bright stars. The night sky is truly a celestial showcase. 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 supergiant 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 supergiant. Rigel’s blue supergiant star has a short lifespan. Blue supergiant 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 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.

 

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."
