Inside the Orion Nebula
Around 1,500 light-years away, hot young stars surrounded by glowing gas make up the Great Nebula in Orion. This massive starbirth region is on the edge of an interstellar molecular cloud. Hubble takes us inside the Orion Nebula with this brightly colored image.
NASA has more:
In the above deep image composite in assigned colors taken by the Hubble Space Telescope wisps and sheets of dust and gas are particularly evident. The Great Nebula in Orion can be found with the unaided eye near the easily identifiable belt of three stars in the popular constellation Orion. In addition to housing a bright open cluster of stars known as the Trapezium, the Orion Nebula contains many stellar nurseries. These nurseries contain much hydrogen gas, hot young stars, proplyds, and stellar jets spewing material at high speeds. Also known as M42, the Orion Nebula spans about 40 light years and is located in the same spiral arm of our Galaxy as the Sun.

Our experience of time may be blinding us to its true nature, say scientists.
- Time may not be passing at all, says the Block Universe Theory.
- Time travel may be possible.
- Your perception of time is likely relative to you and limited.
From questionable shipwrecks to outright attacks, they clearly don't want to be bothered.
- Many have tried to contact the Sentinelese, to write about them, or otherwise.
- But the inhabitants of the 23 square mile island in the Bay of Bengal don't want anything to do with the outside world.
- Their numbers are unknown, but either 40 or 500 remain.
At least he wasn't burned at the stake, right?
- The letter suggests Galileo censored himself a bit in order to fly more under the radar. It didn't work, though.
- The Royal Society Journal will publish the variants of the letters shortly, and scholars will begin to analyze the results.
- The letter was in obscurity for hundreds of years in Royal Society Library in London.
