Could there really be billions of habitable worlds in our galaxy? Learn whether there could really be billions of habitable worlds in our galaxy.
Seven years ago, astronomers boggled when they found the first runaway star flying out of our galaxy at a speed of 1.5 million miles per hour. The discovery intrigued theorists, who wondered: If a star can get tossed outward at such an extreme velocity, could the same thing happen to planets?
Astronomers have put forward a new theory about why black holes become so hugely massive -- claiming some of them have no
In the new book Space Chronicles: Facing the Ultimate Frontier, Neil deGrasse Tyson says America is at a critical moment for future space exploration, as he
In the grand scheme of the solar system, Venus and Earth are almost the same distance from the sun. Yet the planets differ dramatically: Venus is some 100 times hotter than Earth and its days more than 200 times longer. The atmosphere on Venus is so thick that the longest any spacecraft has survived on its surface before being crushed is a little over two hours. There's another difference, too. Earth has a magnetic field and Venus does not -- a crucial distinction when assessing the effects of the sun on each planet.
Obayashi Corp., headquartered in Tokyo, has unveiled a project to build a space elevator by the year 2050 that would transport passengers to a station 36,000
For the first time, buckyballs have been discovered in the cosmos in a solid form in the vicinity of a binary star system 6,500 light-years away.
The European Southern Observatory (Eso) has linked up its four telescopes of the Very Large Telescope (VLT) at the Paranal Observatory to form a virtual
ESO’s Very Large Telescope has delivered the most detailed infrared image of the Carina Nebula stellar nursery taken so far. Many previously hidden features, scattered across a spectacular celestial landscape of gas, dust and young stars, have emerged. This is one of the most dramatic images ever created by the VLT.
Leaner, greener flying machines for the year 2025 are on the drawing boards of three industry teams under contract to the NASA Aeronautics Research Mission Directorate
Mouse skin cells can be converted directly into cells that become the three main parts of the nervous system, according to researchers at the Stanford
NASA's Interstellar Boundary Explorer (IBEX) has captured the best and most complete glimpse yet of what lies beyond the solar system.
Physicists have built an accurate model of part of the solar system inside a single atom. Scientists have shown that they could make an electron orbit the atomic nucleus in the same way that Jupiter
