In this image one can clearly see where the constellations are located. Most importantly, one can see the summer triangle, which is highlighted in orange. The stars that make up this triangle are Vega, Deneb, and Altair. This summer triangle can be seen throughout the summer near midnight from various different locations. A fun fact is that, even though from our point of view we see a triangle, these star are actually thousands of light years away, which means that the triangle is shaped only from Earth.

APOD 4.7
This is the Whirlpool Galaxy at the end of the Big Dipper constellation. Certain astronomers have classified it as an original spiral nebula due to its spiral features.The other galaxy near the top is NGC 5195. These two galaxies are in the boundaries of the Canes Venatici constellation. Even though this image makes them look close together, they are actually 31 million light-years distant from each other.
APOD 4.6
The white looking ant on the left side of the moon is the International Space Station. Although it looks like the image was exposed for a long time, this was only exposed 1/1000 of a second. It is mind blowing how technology allows us to use precise timing to take this photograph. We can also see circular craters, highlands, and marias. If you wish to see the ISS, you can go online and check out when it will be near your area.
APOD 4.5
The constellation viewed here is Cygnus. This is also an imagine of part of the Gamma Cygni nebula. This nebula lies about 1,800 light years away. If you look closely to the right you can see the Barnard 344 cloud. Barnard looks like a black scattered cloud near the star Sadr. The emission nebula is seen in the center. This is the red gas from small nebulas.
APOD 4.4
This image was taken in Guatemala on top of the Santa Maria volcano. If you look at the bottom of the image you can see that there are more volcanos in this area. This area is called the Central America Volcanic Arc. The volcano of fire is seen erupt in the image. However, what draws the attention in this image is the Milky Way Galaxy. One can perfectly see the central band of the Milky Way in a horizontal view point.

APOD 4.3
What you see here is the shortest lunar eclipse of the century! Astronomers say that the moon was fully covered by the Earth's dark umbral shadow.

APOD 4.2
As you can tell, the imagine above is a total solar eclipse. The light that expands from the center is the Sun's light from its outer atmosphere. This is called the corona. Many say that seeing an eclipse is one of the most marvelous phenomenon to see. The fact that eclipses only appear certain times throughout a couple of years and in certain locations on the earth makes them difficult for the world to see. However, an eclipse is coming up within a few years so make sure you are able to see it.
