Latest Astronomical seeing Stories
Observations from ESOâ€™s Very Large Telescope have shed light on the power source of a rare vast cloud of glowing gas in the early Universe.
A consortium of US and Canadian universities on Tuesday announced it has decided to build the world's largest telescope in Hawaii.
A record two-hour observation of Jupiter using a superior technique to remove atmospheric blur has produced the sharpest whole-planet picture ever taken from the ground.
Sometimes seconds count. If a furious, tornado-spitting thunderstorm was bearing down on your home town, a few moments might make all the difference in the world.
Mars will be closer to Earth this month than any time until the year 2016. The red planet is now the brightest "star" in the evening sky and is already above the horizon as evening twilight fades away. But give it at least two more hours until about 8 p.m.
Stunning simulations that give a multi-dimensional glimpse into the interior of stars show that material bubbling around the convection zone induces a rich spectrum of internal gravity waves in the stable layers above and below.
New images and data from ESAâ€™s mission to Venus provide new insights into the turbulent and noxious atmosphere of Earthâ€™s sister planet. What causes violent winds and turbulences? Is the surface topography playing a role in the complex global dynamics of the atmosphere? Venus Express is on the case.
Adaptive Optics -- Adaptive optics is a technology to improve the performance of Earth-based telescopes, reversing the effect of atmospheric distortions. When light from a star or another astronomical object enters the Earth's atmosphere, the different temperature layers and different wind speeds distort and move the image in various ways (see seeing for a proper discussion). The net result is that an 8 meters or 10 meters telescope (like the VLT or Keck), while theoretically capable...
- In Roman antiquity, the return of a person who had been banished, or taken prisoner by an enemy, to his old condition and former privileges.
- In international law, that right by virtue of which persons and things taken by an enemy in war are restored to their former status when coming again under the power of the nation to which they belonged.
