Universe Today — Space and astronomy news
The Falcon 9 and Dragon capsule stand ready for launch prior to the detection of a helium leak in one of the engines forcing a scrub of the launch attempt on April 14. 2014 – now reset to April 18, 2014. Credit: nasatech.net NASA and SpaceX are marching forward towards a Friday, April 18 liftoff attempt for the Falcon 9 rocket sending a commercial Dragon cargo craft on the company’s third resupply mission to the International Space Station following the scrubbed launch attempt on Monday, April 14 – forced by the discovery of a Helium gas leak inside the rocket during the latter stages of the countdown. An on time blastoff of the upgraded Falcon 9 sets the stage for an Easter Sunday rendezvous and berthing of the Dragon resupply spacecraft at the massive orbiting outpost packed with almost 5000 pounds of science experiments and supplies for the six person crew. However the weather prognosis is rather [click to continue…]

Glossary of Astronomical Terms Glossary Absolute magnitude- the brightness a star would be as seen from a distance of 10 parsecs Absolute Zero- the lowest possible temperature, at which substances contain no heat energy, and atomic movement has stopped Accretion- accumulation of dust and gas into larger bodies such as stars, planets, and moons Accretion disk- a disk of hot, glowing matter spiraling into a black hole Active galaxy- a galaxy under-going a violent outburst in its central regions Science for celebrities In January 2007, exasperated by the tide of influential and misleading claims made by celebrities in the public sphere, we worked with scientists to produce Making Sense of Science for Celebrities. Each year since, Sense About Science has reviewed the odd science claims people in the public eye have made - about diets, cancer, magnets, radiation and more - sent in to us by scientists and members of the public. Many of these claims promote theories, therapies and campaigns that make no scientific sense.

Lingua Franca Writing tutors, teaching assistants, usage columnists, and even word-processor grammar-checkers flag passives for “correction” because they have been told they should. (The disastrously confused Page 18 of Strunk & White’s The Elements of Style is often implicated—but don’t get me started on them.) These critics are often clearly inexpert at accurate identification of what they deprecate: collecting published critical comments about the passive by soi-disant rhetoric gurus, I have found that the most frequently occurring score for telling passives from actives is zero (I put this extraordinary statistic aside to discuss another day). Naturally, the critics also have no idea how many they use themselves.

DigitalGlobe is currently restricted to selling imagery with resolution no sharper than 0.5 meters per pixel, but has been pushing [...]

Foundational Questions Institute The Foundational Questions Institute (FQXi) To catalyze, support, and disseminate research on questions at the foundations of physics and cosmology, particularly new frontiers and innovative ideas integral to a deep understanding of reality but unlikely to be supported by conventional funding sources. FQXi has five goals: {*style:<ul style="padding-left:20px;"><li> To expand the purview of scientific inquiry to include scientific disciplines fundamental to a deep understanding of reality, but which are currently largely unsupported by conventional grant sources To redress incrementalism in research programming by establishing or expanding new "islands" of understanding via flexible funding of high-risk, high-reward research in these areas

Hubble's Best Photos Milky Way The Hubble Space Telescope has dazzled us for years with its unbelievable images of breathtaking cosmic phenomena. In honor of its 20th anniversary in orbit, we're sharing what we think are some of Hubble’s best photos. This composite color infrared image is a sweeping panorama of our galactic home – the Milky Way.

Solar System, Solar System Information Our Cosmic Neighborhood From our small world we have gazed upon the cosmic ocean for thousands of years. Ancient astronomers observed points of light that appeared to move among the stars. They called these objects "planets," meaning wanderers, and named them after Roman deities—Jupiter, king of the gods; Mars, the god of war; Mercury, messenger of the gods; Venus, the goddes of love and beauty, and Saturn, father of Jupiter and god of agriculture. The stargazers also observed comets with sparkling tails, and meteors or shooting stars apparently falling from the sky. Since the invention of the telescope, three more planets have been discovered in our solar system: Uranus (1781), Neptune (1846), and, now downgraded to a dwarf planet, Pluto (1930).
