Taking at least one or two economics or business courses should be mandatory. That way I’d hear fewer business ideas that start with, “It’s like Facebook, only better.” One of the first lessons of economics is the importance of competition. Specifically, that if you try to do what everyone else is doing, you’ll probably fail. …

An amateur astronomer caught a photograph of what appears to be an asteroid slamming into Jupiter.


A photograph captured by amateur astronomer Ethan Chappel appears to show an asteroid slamming into the gas giant Jupiter on Wednesday (Aug. 7). So far, astronomers are still waiting to see whether anyone else spotted the sudden flash, which was located over the planet’s South Equatorial Belt.

University of Sydney astronomers, working with international colleagues, have found a star system like none seen before in our galaxy.


The scientists believe one of the stars—about 8000 light years from Earth—is the first known candidate in the Milky Way to produce a dangerous gamma-ray burst, among the most energetic events in the universe, when it explodes and dies. The system, comprising a pair of scorchingly luminous stars, was nicknamed Apep by the team after the serpentine Egyptian god of chaos. One star is on the brink of a massive supernova explosion.

In an attempt to create a "Noah’s ark" or a "back-up" for the Earth, non-profit organization The Arch Mission sent a lunar library — a stack of DVD-sized disks that acts as an archive of 30 million pages of information about the planet — to the moon. Along with the library, Arch Mission sent human DNA samples and a payload of tardigrades, which had been dehydrated, into space.
"We chose them because they are special. They are the toughest form of life we know of. They can survive practically any planetary cataclysm. They can survive in the vacuum of space, they can survive radiation," Nova Spivack, co-founder of the Arch Mission Foundation, said. Tardigrades have eight legs with claws at the end, a brain and central nervous system, and a sucker-like pharynx behind their mouth, which can pierce food.

Until now, the understanding of the galaxy’s shape had been based upon indirect measurements of celestial landmarks within it and inferences from structures observed in other galaxies.


The Milky Way is not flat, as previously thought, but warped and twisted in shape, according to the most detailed map ever constructed.   Astronomers at the University of Warsaw used a telescope in the Chilean Andes to measure the distances between the sun and 2,400 stars to build a three-dimensional picture of the galaxy we live in.  In doing so, they showed it is in fact a disk, with four major spiral arms and a pole-like core running through the middle.
