As technological innovative and higher latest skyscrapers can be, they still need to rely on the support to the ground. So a higher heights usually means more unstableness as well as weaker capacity to resist disasters. The project proposes a mega hex grid that evolves around the earth circumference at a stratosphere heigh, the principle [...]
A blood-red comet appears in the sky. People quake in its wake. This phenomenon, which happens in the second season of the medieval fantasy Game of Thrones, had us all wondering – can you ever actually see a red comet? We talked to Matthew Knight, an astronomer at the Lowell Observatory in Arizona who observes comets. He [...]

Size might matter when it comes to stars having habitable environments for planets, and in this case smaller might be better, as well as closer to Earth. A new study indicates that low mass stars may be the most abundant planet hosts in our galaxy. And since these smaller stars like M-dwarfs are plentiful, [...]
In this new video from Big Think, astrophysicist Neil deGrasse Tyson says he’s almost embarrassed for our species that it takes a warning shot across our bow before legislators take seriously the advice they’ve been receiving from astronomers about getting serious about asteroid detection and deflection; that it’s a matter of when not if Earth will get [...]
After analyzing the first powder ever drilled from the interior of a Martian rock,NASA’s Curiosity rover discovered some of the key chemical ingredients necessary for life to have thrived on early Mars billions of years ago.
Scientists at the British Antarctic Survey along with a host of international collaborators, have been working to present the most detailed map yet of Antarctica’s landmass, the Bedmap2. In addition, the map allows scientists to analyze, in much greater detail, the bed below the Antarctic ice sheet.
Bedmap2 reveals a landscape of mountain ranges and plains cut by gorges and valleys much deeper than previously seen.
NASA’s Wide-field Infrared Survey Explorer (WISE) has discovered a pair of stars that has taken over the title for the third-closest star system to the sun. The duo is the closest star system discovered since 1916. Both stars in the new binary system are “brown dwarfs,” which are stars that are too small in mass [...]
Cats, celebrities and fictional creatures all have a home in the asteroid belt. That’s because the people that found these asteroids often have the privilege of naming the minor planets after anything they want — with a few guidelines, of course.
by Elizabeth Renter When we talk about the medicinal benefits of marijuana, those who disapprove of its use tend to roll their eyes. But the fact is, this powerful plant has numerous potential applications in healthcare and pain management in particular. A new study has once again demonstrated that the vilified plant can safely and [...]
According to the American government, their involvement in the Vietnam War started on November 1, 1955, and lasted until the Americans pulled out in early March 1973. The War, and the protest movement it created, defined the baby boomer generation.
Decades later, this war is still shrouded in myths, either from the propaganda during the war, or from the typical Hollywood dramatization that succeeding generations were weaned upon.
