Crescent Moon Occultation Image Credit & Copyright: Fefo Bouvier

Explanation: On February 22, a young Moon shared the western sky at sunset with bright planets Venus and Jupiter along the ecliptic plane. The beautiful celestial conjunction was visible around planet Earth. But from some locations Jupiter hid for a while, occulted by the crescent lunar disk. The Solar System’s ruling gas giant was captured here just before it disappeared behind the the Moon’s dark edge, seen over the Río de la Plata at Colonia del Sacramento, Uruguay. In the serene river and skyscape Venus is not so shy, shining brightly closer to the horizon through the fading twilight. Next week Venus and Jupiter will appear even closer in your evening sky.

NGC 2170: Angel Nebula Abstract Art Image Credit & Copyright: David Moulton

Explanation: Is this a painting or a photograph? In this celestial abstract art composed with a cosmic brush, dusty nebula NGC 2170, also known as the Angel Nebula, shines just above the image center. Reflecting the light of nearby hot stars, NGC 2170 is joined by other bluish reflection nebulae, a red emission region, many dark absorption nebulae, and a backdrop of colorful stars. Like the common household items that abstract painters often choose for their subjects, the clouds of gas, dust, and hot stars featured here are also commonly found in a setting like this one – a massive, star-forming molecular cloud in the constellation of the Unicorn (Monoceros). The giant molecular cloud, Mon R2, is impressively close, estimated to be only 2,400 light-years or so away. At that distance, this canvas would be over 60 light-years across.

M78 // Capturing Ancient Photons

A beautiful series of reflection nebulae make up M78. These reflection nebulae, like their name suggests, contain little ionized gas and primarily reflect the light of nearby stars. In this case, it is only two stars' light that the gas is reflecting despite containing a few hundred young stars within.

Explanation: Ridges of glowing interstellar gas and dark dust clouds inhabit the turbulent, cosmic depths of the Lagoon Nebula. Also known as M8, The bright star forming region is about 5,000 light-years distant. It makes for a popular stop on telescopic tours of the constellation Sagittarius toward the center of our Milky Way Galaxy. Dominated by the telltale red emission of ionized hydrogen atoms recombining with stripped electrons, this deep telescopic view of the Lagoon’s central reaches is about 40 light-years across. The bright hourglass shape near the center of the frame is gas ionized and sculpted by energetic radiation and extreme stellar winds from a massive young star.
