Tomorrow, on June 8, beginning shortly after 5 hrs UT, a large part of the world will be sharing a unique sight never seen by any person now living. During a little more than six hours, planet Venus will cross the face of the Sun, offering a wonderful show for everybody to admire. Nobody should miss the opportunity to witness this great event! And - good luck! - it appears that the observing condition prospects are rather favourable in large areas of the world.
Nevertheless, should you be as unlucky as astronomer Le Gentil in 1769 who, having traversed a large portion of the globe, enduring all the perils of a long sea-voyage, and waiting for 8 years for the transit to occur, was unable to observe it because of a vexatious, black cloud that covered the Sun, you need not despair. There will be ample opportunity to witness this event from the VT-2004 Central Display page (and other websites).
This page, powered by Akamai and therefore mirrored on many hundreds of sites all over the world, will offer selected images from the event, acquired by our colleagues at the large solar telescopes, from the Canary Island to China. All images will be chosen and commented live by a team of professional astronomers in the "VT-2004 Control Room" at the ESO headquarters (Garching, Germany), who will guide you through the various phases of this memorable event and provide a running commentary, beginning before dawn (in Central Europe) on the Day of the Transit and only ending when Venus is well beyond the solar disc.

Physicists at the Laboratory for Attosecond Physics, which is jointly run by Ludwig-Maximilians-Universität and the Max Planck Institute of Quantum Optics, have developed a high-power laser system that generates ultrashort pulses of light covering a large share of the mid-infrared spectrum. The researchers envisage a wide range of applications for the technology – in the early diagnosis of cancer, for instance.
Molecules are the building blocks of life. Like all other organisms, we are made of them. They control our biorhythm, and they can also reflect our state of...
University of Connecticut researchers have created a biodegradable composite made of silk fibers that can be used to repair broken load-bearing bones without the complications sometimes presented by other materials.
Repairing major load-bearing bones such as those in the leg can be a long and uncomfortable process.
Study published in the journal ACS Applied Materials & Interfaces is the outcome of an international effort that included teams from Dresden and Berlin in Germany, and the US.
Scientists at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) together with colleagues from the Helmholtz-Zentrum Berlin (HZB) and the University of Virginia...
Novel highly efficient and brilliant gamma-ray source: Based on model calculations, physicists of the Max PIanck Institute for Nuclear Physics in Heidelberg propose a novel method for an efficient high-brilliance gamma-ray source. A giant collimated gamma-ray pulse is generated from the interaction of a dense ultra-relativistic electron beam with a thin solid conductor. Energetic gamma-rays are copiously produced as the electron beam splits into filaments while propagating across the conductor. The resulting gamma-ray energy and flux enable novel experiments in nuclear and fundamental physics.
The typical wavelength of light interacting with an object of the microcosm scales with the size of this object. For atoms, this ranges from visible light to...
Stable joint cartilage can be produced from adult stem cells originating from bone marrow. This is made possible by inducing specific molecular processes occurring during embryonic cartilage formation, as researchers from the University and University Hospital of Basel report in the scientific journal PNAS.
Certain mesenchymal stem/stromal cells from the bone marrow of adults are considered extremely promising for skeletal tissue regeneration. These adult stem...
