NGC 6050/IC 1179 (Arp 272) is a remarkable collision between two spiral galaxies, NGC 6050 and IC 1179, and is part of the Hercules Galaxy Cluster, located in the constellation of Hercules. The galaxy cluster is part of the Great Wall of clusters and superclusters, the largest known structure in the Universe. The two spiral galaxies are linked by their swirling arms. Arp 272 is located some 450 million light-years away from Earth and is number 272 in Arp's Atlas of Peculiar Galaxies. Interactive Sky Map

Your Age On Other Worlds

The Days (And Years) Of Our Lives Looking at the numbers above, you'll immediately notice that you are different ages on the different planets. This brings up the question of how we define the time intervals we measure. What is a day?

The Elegant Universe: Part 3 PBS Airdate: November 4, 2003 NARRATOR: Now, on NOVA, take a thrill ride into a world stranger than science fiction, where you play the game by breaking some rules, where a new view of the universe pushes you beyond the limits of your wildest imagination. This is the world of "string theory," a way of describing every force and all matter from an atom to earth, to the end of the galaxies—from the birth of time to its final tick, in a single theory, a "Theory of Everything."

Credit: European Southern Observatory Two teams of researchers are now competing to develop a device that could profoundly change our understanding of the universe…but you’d be forgiven if you mistook it for a vaguely menacing hair-restoration product. Called a “laser frequency comb,” these are special laser systems that rapidly emit pulses of light across a wide range of frequencies or colors. In a plot of the emitted light, each distinct frequency appears as a peak; collectively, all the frequencies resemble a fine-toothed comb. And by examining starlight through the teeth of a laser comb, astronomers could begin finding Earth-like extrasolar planets on the cheap using ground-based observatories rather than expensive space telescopes. A star’s spectrum, its component colors of light, can reveal whether or not it has planets circling it. Planet Hunting, Down to Earth Planet Hunting, Down to Earth
