Large water reservoirs at the dawn of stellar birth ESA's Herschel space observatory has discovered enough water vapour to fill Earth's oceans more than 2000 times over, in a gas and dust cloud that is on the verge of collapsing into a new Sun-like star. Stars form within cold, dark clouds of gas and du...
Astronomers have identified the smallest known black hole. The puny object weighs only 3.8 times the Sun's mass and spans just 24 kilometres across. The black hole is believed to have formed from the collapse of a massive star when it ran out of fuel. Astronomers are not sure what the smallest possibl...

Title: A Silurian armoured aplacophoran and implications for molluscan phylogeny Authors: Mark D. Sutton, Derek E. G. Briggs, David J. Siveter, Derek J. Siveter & Julia D. Sigwart The Mollusca is one of the most diverse, important and well-studied invertebrate phyla; however, relationshi...
Title: TA-DA: a Tool for Astrophysical Data Analysis Authors: Nicola Da Rio, Massimo Robberto We present TA-DA, a new software aimed at greatly simplify and improve the analysis of stellar photometric data in comparison with theoretical models, and allow the derivation of stellar parameters fr...
Einstein's "Zur Elektrodynamik bewegter Körper" ("On the Electrodynamics of Moving Bodies"), his third paper that year, was received on June 30 and published September 26. It reconciles Maxwell's equations for electricity and magnetism with the laws of mechanics, by in...
Title: Galactic bar: normal mode of the stellar disk or superposition of transient spirals? Authors: Evgeny Polyachenko Several mechanisms of bar formation in stellar galactic disks are considered, including Toomre swing amplification and normal mode approach. On example of the well-known m...
Title: Astro-quark matter: a challenge facing astroparticle physics Authors: Renxin Xu (PKU) Quark matter both in terrestrial experiment and in astrophysics is briefly reviewed. Astrophysical quark matter could appear in the early Universe, in compact stars, and as cosmic rays. Emphasis is p...
Free program makes computer graphics more realistic Computer-generated images can be a little more realistic -- and a lot cheaper to make -- with a rendering program created by a Cornell graduate student. Wenzel Jakob has just released a major new version of Mitsuba, a free, open-source rendering...

Title: Efficient deconvolution methods for astronomical imaging: algorithms and IDL-GPU codes Authors: M. Prato, R. Cavicchioli, L. Zanni, P. Boccacci, M. Bertero The Richardson-Lucy method is the most popular deconvolution method in astronomy because it preserves the number of counts and t...
Tanzanite Cutting Company Launches New Tanzanite Cut A local Tanzanite cutting firm that specialises in cutting the finest 1% of Tanzanites mined has recently developed a new style of cut which they launched last week at a gala in Cape Town, South Africa. The cut combines the traditional portugues...
