  • Venus will take six hours to march across the star’s face, appearing as an inky black dot in silhouette against the looming solar disk
  • Because the planet’s orbit is slightly off-kilter, its solar transits come in pairs spaced eight years apart, with more than 100 years between pairs.
  • Paris Observatory, who will join Venus Express team members in Svalbard, Norway to observe the transit against the midnight sun.

  • its planetprint produces the type of dimming that occurs when exoplanets periodically block their stars’ light. Astronomers have been able to study the atmospheres of Jupiter-sized exoplanets, but similar observations of terrestrial planets are still a thing of the future.
  • Maybe one day we will be able to measure the same light that is filtered from the atmospheres of exoplanets – exo-Venuses and exo-Earths
  • such observations aren’t so simple. “Big mirrors and sensitive detectors are not good things to point at the sun
  • capture sunlight reflected off the face of the moon during the transit

  • The creature looks a bit like a scaled-down Tyrannosaurus rex, but with even smaller arms.
  • this six-meter (20-foot) long creature creature "has completely reduced arms and tiny claws, which implies that it used only its very sharp teeth to feed itself,"

  • professor of business administration at the University of Illinois
  • moderate level of noise not only enhances creative problem-solving but also leads to a greater adoption of innovative products in certain settings
  • explores how a moderate-level of ambient noise (about 70 decibels, equivalent to a passenger car traveling on a highway) enhances performance on creative tasks and increases the likelihood of consumers purchasing innovative products.
  • ...5 more annotations...
  • researchers also studied how a high level of noise (85 decibels, equivalent to traffic noise on a major road) hurts creativity by reducing information processing.
  • around 70 decibels is the sweet spot
  • An increased level of distraction makes you think ‘out-of-the-box’ – what we call abstract thinking or abstract processing, which is a hallmark of increased creativity
  • go beyond that moderate level of noise what happens is that distraction becomes so huge that it really starts affecting the thought process
  • a moderate level of noise produces just enough distraction to lead to higher creativity, but a very high level of noise induces too much distraction, which actually reduces the amount of processing, thus leading to lower creativity

  • announced his team’s development of modular devices that could be used to gather solar energy in orbit, working atop an experimental “space web” structure developed by graduate students at the university’s Department of Mechanical and Aerospace Engineering.
  • “By using either microwaves or lasers we would be able to beam the energy back down to earth, directly to specific areas. This would provide a reliable, quality source of energy and would remove the need for storing energy coming from renewable sources on ground as it would provide a constant delivery of solar energy.”

  • Two Roman-era shipwrecks have been found in deep water off a western Greek island, challenging the conventional theory that ancient shipmasters stuck to coastal routes rather than risking the open sea, an official said Tuesday.
  • They lay between 1.2 and 1.4 kilometers (0.7-0.9 miles) deep in the sea between Corfu and Italy.
  • among the deepest known ancient wrecks in the Mediterranean, apart from remains found in 1999 of an older vessel some 3 kilometers (1.8 miles) deep off Cyprus.

  • A Greek oceanographic vessel using side-scan radar and robot submarines took footage of scattered cargo — storage jars, or amphorae, used to carry foodstuffs and wine — cooking utensils for the crew, anchors, ballast stones and what could be remains of the wooden ships.
  • deep wrecks are very important because they are almost always more intact than those found in shallow water

  • Solar power plants in Germany have set a new record. “Never before anywhere has a country produced as much photovoltaic electricity,"
  • plants peaked at 22 gigawatts of output for a few hours over the weekend, on Friday and Saturday
  • they yielded almost half the country's energy mid-day electricity needs
  • ...3 more annotations...
  • 22 gigawatts is up from 14 GW a year ago. Also, this 22 gigawatts of output is equal to about 20 nuclear plants.
  • 2012 Environment Ministry report showed that German taxpayers pay an extra four billion euros per year on top of their electricity bills to support solar power
  • The new record-breaking figures from Germany, however, do not quiet some energy experts who stress that without good storage strategies for excess power, such record-breaking numbers are not meaningful. They say the real point is to get consistently large percentages of power from renewable sources.
