APOD 1.5

I found this picture to be quite interesting, as it displays two natural phenomena: a pillar of volcanic light, and the green lights in the sky, which are known as an aurora. This photograph was captured earlier this month, and features an area known as the Holuhraun Lava Field. The red pillar of light emerges from the volcano Bárðarbunga. The red line is the eruptions reflection from
crystals of atmospheric light. Also seen in this photograph are 4 well-known constellations. From left to right they are Hercules, Corona Borealis (Northern Crown), Bootes (Herdsman) , and the bottom part of Ursa Major (Great Bear).

APOD 1.4

Pictured here is our home galaxy, The Milky Way, as seen from the Atacama Salt Flat in Northern Chile. In the upper right-hand corner of the photograph, the center of the Milky Way Galaxy is visible. In close proximity to the center of the galaxy, Antares-a major star in the constellation Scorpius- is also visible. On the left side of the photograph, there are two bright clusters. These two clusters are known as the Small & Large Magellanic Cloud Galaxies (SMC and LMC). This truly spectacular photograph features an innumerable amount of stars as well as a stunning image of a band of the Milky Way running diagonally across the sky.

APOD 1.3

This photograph of a triangular beam of light known as Zodiacal Light was taken at the Las Campanas Observatory in Chile's Atacama Desert. This zodiacal light looks as if it is a sunrise, but in reality, this photograph was taken hours before the sun rose. This "false dawn" is caused by dust particals in the ecliptic plane that are scattered by sunlight, which would otherwise not be visible. Aside from the Zodiacal Light Beam, Orion and the California Nebula are also visible. This photograph is very unique because something like this cannot be seen from my location-Florida.

 

APOD 1.2

 This photograph is known as Airglow Ripples over Tibet. What is displayed here are immense circular ripples of air which appear to glow, following a storm in Bangledash. This rare event is caused by chemiluminescence, and the pattern formed is due to atmospheric gravity waves. These bright, spectacular colors prevent the night sky from becoming totally dark, and are an amazing sight to gaze upon.

 

APOD 1.1

Pictured in this photograph is Spiral Galaxy NGC 6744. This galaxy is slightly larger than our own Milky Way, by about 65,000 light years. This beautiful, colorful galaxy greatly resembles ours, and is surrounded by clusters of other stars and galaxies. The possibility of something as vast as this, and as vast as the universe astounds me, and blows my mind every time I think about it. It is amazing to think that there are approximately 100 billion known galaxies in the Universe.
