Like an illustration in a galactic Just So Story, the Elephant's Trunk Nebula winds through the emission nebula and young star cluster complex IC 1396, in the high and far off constellation of Cepheus. Of course, the cosmic elephant's trunk is over 20 light-years long. This composite was recorded through narrow band filters that transmit the light from ionized hydrogen, sulfur, and oxygen atoms in the region. The resulting image highlights the bright swept-back ridges that outline pockets of cool interstellar dust and gas. Such embedded, dark, tendril-shaped clouds contain the raw material for star formation and hide protostars within the obscuring cosmic dust. Nearly 3,000 light-years distant, the relatively faint IC 1396 complex covers a large region on the sky, spanning over 5 degrees. This close-up mosaic covers a 2 degree wide field, about the size of 4 Full Moons.

^^^The reason why they would see dinosaurs is because of a delay in light from traveling so far. Everything we see is because of light refraction. So being 65 million light years away would give delay imagery of 65 million years ago. 65 million years ago would be 1 million years before the end of the Cretaceous period.

It is one of the brightest planetary nebulae on the sky -- what should it be named? First discovered in 1878, nebula NGC 7027 can be seen toward the constellation of the Swan (Cygnus) with a standard backyard telescope. Partly because it appears there as only an indistinct spot, it is rarely referred to with a moniker. When imaged with the Earth-orbiting Hubble Space Telescope, however, great details are revealed. Studying Hubble images of NGC 7027 have led to the understanding that it is a planetary nebula that began expanding about 600 years ago, and that the cloud of gas and dust is unusually massive as it appears to contain about three times the mass of our Sun. Pictured above in assigned colors, the resolved, layered, and dust-laced features of NGC 7027 might remind sky enthusiasts of a familiar icon that could be the basis for an informal name.

The Paramecium has sunburst-shaped contractile vacuoles, which pump excess water out of the cell.

magnetic filament of solar material erupted on the sun in late September, breaking the quiet conditions in a spectacular fashion. The 200,000 mile long filament ripped through the sun's atmosphere, the corona, leaving behind what looks like a canyon of fire. The glowing canyon traces the channel where magnetic fields held the filament aloft before the explosion. Visualizers at NASA's Goddard Space Flight Center in Greenbelt, Md. combined two days of satellite data to create a short movie of this gigantic event on the sun.

'Making sense of string theory'

In clear, nontechnical language, string theorist Brian Greene explains how our understanding of the universe has evolved from Einstein's notions of gravity and space-time to superstring theory, where minuscule strands of energy vibrating in 11 dimensions create every particle and force in the universe.

A Linophryne brevibarbata species of anglerfish. That attachment at the rear of her belly is not an appendage. It's a tiny male that has permanently fused to her. Had the pair not been caught, he would have lived the rest of his life like this, supplying sperm and pulling nourishment from her blood.

Can we perceive objects and events beyond the world detected by our five senses? The true limits of our human brain remain a scientific mystery. New studies in neuroscience are showing that our minds can really detect events and objects that our conscious selves know nothing about. Can we predict events in the future? Is there such a thing as a global consciousness? Could physical laws on the cusp of being discovered be at the root of all this?

Lightning from Hell

There are few phenomenon on Earth as terrifying, devastating, and interesting as volcanic eruptions. Massive amounts of rock and ash soar high into the atmosphere as the Earth's crust opens and the great forces present within the mantle are released. Volcanic eruptions are one of the most energetic events on the planet; only a few other natural events can compare - lightning being one of them.

In nearly every part of the world (other than very cold regions), thunderstorms are a common occurrence, and they are usually nothing to worry about. The most severe storms have several dangerous components, such as floods, winds/tornadoes, hail, and of course the beautiful lightning. When electrical charges due to wind and ice in the atmosphere build, tremendous amounts of energy are released upon a ground source (trees, buildings, other clouds, etc.). What can be more amazing than volcanoes or lightning? Volcanic lightning.
