The Worlds of David Darling

The Worlds of David Darling
Rings around an asteroid (Mar 30, 2014) Observations at many sites in South America, including ESO's La Silla Observatory, have made the surprise discovery that the remote asteroid Chariklo is surrounded by two dense and narrow rings. This is the smallest object by far found to have rings and only the fifth body in the Solar System — after the much larger planets Jupiter, Saturn, Uranus, and Neptune — to have this feature. The origin of these rings remains a mystery, but they may be the result of a collision that created a disk of debris.

Space.com Buy This Infographic as a Full-Size Poster Astronomers have discovered more than 700 alien planets beyond the solar system, and the count is rising all the time. Some are large and hot, and others are smaller and cooler, but scientists are still on the lookout for an Earth twin. They just got closer, with the announcement Dec. 5 of a planet found by NASA's Kepler space telescope to lie in the habitable zone around its star where liquid water, and perhaps life, could exist.

Accelerating Future » 10 Interesting Futuristic Materials 1. Aerogel Aerogel holds 15 entries in the Guinness Book of Records, including "best insulator", and "lowest-density solid". Meteorite older than Solar System Organic globules found in the Tagish Lake meteorite fragments may predate the solar system, according to a new U.S. study Credit: University of Calgary SYDNEY: A meteorite discovered in Canada may be older than the Solar System, according to a new U.S. study. Samples taken from the Tagish Lake meteorite, discovered in 2000, have revealed evidence of organic matter that predates our Sun and Solar System, according to the study, published in today’s edition of the U.S. journal Science. According to the researchers, the meteorite most likely originated at the outer regions of the Kuiper Belt or in the cold molecular cloud that gave birth to the Solar System.

Russia to join European Mars mission MOSCOW, April 6 (UPI) -- Russia's space agency Roscosmos said it has agreed to participate in a Mars research project with the European Space Agency. The announcement came following a meeting between Roscosmos head Vladimir Popovkin and ESA chief Jean-Jacques Dordain in Moscow Friday. "The sides consider this project feasible and promising," Popovkin's spokeswoman Anna Vedishcheva told RIA Novosti.

10 Strange Things About The Universe Space The universe can be a very strange place. While groundbreaking ideas such as quantum theory, relativity and even the Earth going around the Sun might be commonly accepted now, science still continues to show that the universe contains things you might find it difficult to believe, and even more difficult to get your head around.

Nanotech breakthrough: get ready for graphene The exciting one-atom thick super material can now be produced in ample quantities and high quality. Rapid improvements in nanotechnology are now expected. Technology improvements are about to get dramatically ultra-fast. Exciting sustaining and disruptive innovations are on the way for just about every digital appliance, from touchscreen tablet computing to solar cells, according to a Science Daily report. Graphene is a new form of carbon, one atom in thickness, extremely strong and highly conducive. High performance can be achieved with graphene transistors that can operate at much faster speeds and in higher heat conditions compared to current silicon chip technology.

NASA and NSF-Funded Research Finds First Potentially Habitable Exoplanet NASA and NSF-Funded Research Finds First Potentially Habitable Exoplanet A team of planet hunters from the University of California (UC) Santa Cruz, and the Carnegie Institution of Washington has announced the discovery of a planet with three times the mass of Earth orbiting a nearby star at a distance that places it squarely in the middle of the star's "habitable zone." This discovery was the result of more than a decade of observations using the W. M. Keck Observatory in Hawaii, one of the world's largest optical telescopes. logy Magazine In new research, scientists have attempted to determine the precise conditions necessary for planets to form in a star system. Jarrett Johnson and Hui Li of Los Alamos National Laboratory assert that observations increasingly suggest that planet formation takes place in star systems with higher metallicities. Astronomers use the term “metallicity” in reference to elements heavier than hydrogen and helium, such as oxygen, silicon, and iron. In the “core accretion” model of planetary formation, a rocky core gradually forms when dust grains that make up the disk of material that surrounds a young star bang into each other to create small rocks known as “planetesimals”.

Welcome 2012! New Year's Around the World - Alan Taylor - In Focus As midnight marched across the world's time zones last night, people welcomed the start of a new year, ushering out the old and toasting the new. From Beijing to Moscow, Beirut to Paris, and London to New York, parties, fireworks and festivals welcomed 2012, the Year of the Dragon in the Chinese Lunar Calendar. Gathered here are images from these celebrations last night, and the many people who took part. Your Sky by John Walker Welcome to Your Sky, the interactive planetarium of the Web. You can produce maps in the forms described below for any time and date, viewpoint, and observing location. If you enter the orbital elements of an asteroid or comet, Your Sky will compute its current position and plot it on the map.

Faster then light travel to be rechecked in May 2012 UPDATE 8 June 2012 Neutrinos sent from CERN to Gran Sasso respect the cosmic speed limit At the 25th International Conference on Neutrino Physics and Astrophysics in Kyoto today, CERN Research Director Sergio Bertolucci presented results on the time of flight of neutrinos from CERN to the INFN Gran Sasso Laboratory on behalf of four experiments situated at Gran Sasso. The four, Borexino, ICARUS, LVD and OPERA all measure a neutrino time of flight consistent with the speed of light. This is at odds with a measurement that the OPERA collaboration put up for scrutiny last September, indicating that the original OPERA measurement can be attributed to a faulty element of the experiment’s fibre optic timing system. “Although this result isn’t as exciting as some would have liked,” said Bertolucci, “it is what we all expected deep down.

Alien Worlds: Shedding light on our unearthly universe We've been enraptured by this most eye-catching of constellations since ancient times. It's a beautiful sight that dominates our winter skies in northern latitudes. The constellation was named after Orion the Hunter, a character in Greek mythology. But those ancient stargazers could never have dreamt of the tremendous details that modern astronomy has uncovered about this star system. Story continues below animation. Download this animation from iTunes U Super-Earth Alien Planets May Hang on to Life More Tightly Life may not get blasted off any of the known "super-Earth" worlds as readily as it can from our planet, scientists find. The discovery suggests that any intelligent aliens that develop on such planets might find it hard to rocket off them and travel to other worlds as well, researchers added. As scientists began discovering alien worlds around other stars, one class of planet that began appearing was super-Earths, planets larger than our own that can reach up to 10 times Earth's mass. A number of these super-Earths apparently lie in the habitable zones of their stars, where temperatures can support liquid water on their surfaces and thus, potentially, life as we know it.
