I really love this site and 
this is an awesome photo!
Kind of makes me realize how
small this planet Earth is....

Astronomy Picture of the Day

Discover the cosmos! Each day a different image or photograph of our fascinating universe is featured, along with a brief explanation written by a professional astronomer.

Explanation: NGC 1333 is seen in visible light as a reflection nebula, dominated by bluish hues characteristic of starlight reflected by dust. A mere 1,000 light-years distant toward the heroic constellationPerseus, it lies at the edge of a large, star-forming molecular cloud. This striking close-up view spans about two full moons on the sky or just over 15 light-years at the estimated distance of NGC 1333. It shows details of the dusty region along with hints of contrasting red emission from Herbig-Haro objects, jets and shocked glowing gas emanating from recently formed stars. In fact, NGC 1333 contains hundreds of stars less than a million years old, most still hidden from optical telescopes by the pervasive stardust. The chaotic environment may be similar to one in which our own Sun formed over 4.5 billion years ago.

Gas, dust, and stars are scattered across the image. A dark silhouette that looks like an eagle swoops downward towards three small pillars 
of gas. Other gas and dust pillar-like features reach out of the surrounding nebula. A central cluster of stars sits beneath the eagle silhouette.

Explanation: What looks as if it is going to swallow the great Pillars of Creation? The Eagle Nebula (M16) is not a bird, a plane, or Superman. M16 is actually a combination of several celestial objects. NGC 6611 is the young star cluster that appears to peak out beneath the Eagle’s “wings”. The ultraviolet light from these stars ionizes the surrounding gas, creating the emission nebula IC 4703. The Stellar Spire is seen reaching towards the Pillars of Creation from the left. Both are structures of cold gas and dust that are optimal for star formation. Some astronomers previously thought the Pillars of Creation had been evaporated away by a supernova. Because M16 is 6,000 light years away, we would not be able to see the Pillars’ destruction for thousands more years. However, there is no conclusive evidence of the theorized supernova, so the Pillars of Creation will likely continue to create stars for millions of years.

Explanation: Could the Little Mermaid turn into stardust instead of seafoam? It would seem so in this beautiful nebula. The featured image shows the Mermaid Nebula, also known as the Betta Fish Nebula, which is part of the G296.5+10.0 Supernova Remnant. The blue color visible here originates from doubly ionized oxygen (OIII), while the deep red is emitted by hydrogen gas. Estimated to be located a few thousand light-years away and about 10,000 years old, this nebula was formed when a massive star exploded as a supernova. It left behind a peculiar pulsar, a young radio-quiet neutron star that spins around about twice every second. The bright stars shown in the image are unassociated with the nebula. The pulsar can be detected in the X-rays but it does not have a confirmed detection in the optical (visible light) so far. As a result, the pulsar itself is not visible in this image.
