The Krubera Cave is the world’s deepest cave. It is 2197 meters deep and will take you approximately an entire month to get to the bottom. Here is a map of this place.
Finding Neutrinos - Sixty Symbols
I was somewhat lucky enough to be doing the physics A2 when all the ‘are neutrinos faster than light’ stuff was floating around so we would spend lessons just asking questions.
What it would look like if the Orion Nebula was a distance of 4 light years away.

The heart of the Rosette Nebula and its details
In the heart of the Rosette Nebula lies a bright open cluster of stars that lights up the nebula. The stars of NGC 2244 formed from the surrounding gas only a few million years ago. The above image taken in January using multiple exposures and very specific colors of Sulfur (shaded red), Hydrogen (green), and Oxygen (blue), captures the central region in tremendous detail. A hot wind of particles streams away from the cluster stars and contributes to an already complex menagerie of gas and dust filaments while slowly evacuating the cluster center. The Rosette Nebula’s center measures about 50 light-years across, lies about 4,500 light-years away, and is visible with binoculars towards the constellation of the Unicorn (Monoceros). [via APOD]

The Trifid Nebula - M20
The massive star factory known as the Trifid Nebula was captured in all its glory with the Wide-Field Imager camera attached to the MPG/ESO 2.2-metre telescope at ESO’s La Silla Observatory in northern Chile. The nebula is named after the dark dust bands that trisect its glowing heart, the Trifid Nebula is a rare combination of three nebulae types that reveal the fury of freshly formed stars and point to more star birth in the future.
