New Imaging Technology Takes Cues From Astronomy And Ophthalmology To Make Microscope Images Sharper

Howard Hughes Medical Institute The complexity of biology can befuddle even the most sophisticated light microscopes. Biological samples bend light in unpredictable ways, returning difficult-to-interpret information to the microscope and...

ESO Calendar 2014 Available Now
2013-10-14 09:49:55

ESO The European Southern Observatory’s 2014 calendar is now available to buy from the ESO online shop, or to download as a free PDF file. The calendar’s cover features a spectacular image of the Carina Nebula captured by the VLT Survey Telescope at ESO’s Paranal Observatory in Chile. The calendar itself is packed full of images of the cosmos as well as pictures of the ESO telescopes in the desolate landscapes of the Atacama Desert. Highlights include a landscape picture for...

Perseid Meteor Shower Will Also Provide Celestial Pollution
2013-08-10 06:31:00

[ Watch the Video: Laser Lights Criss Cross Hawaiian Skies ] April Flowers for redOrbit.com - Your Universe Online The annual Perseid Meteor Shower will peak this weekend. As redOrbit’s Lawrence Leblonde reported, scientists are predicting that due to a lack of strong moonlight, this could be one of the most impressive shows in years. But that isn’t the reason scientists are so happy about the shower. In addition to a fantastic light show every summer, the Perseid shower provides...

Adaptive Optics Details New Space Images From Gemini Observatory
2013-07-03 11:05:47

Brett Smith for redOrbit.com - Your Universe Online Scientists at the Gemini Observatory in Chile have just released the first new images of space created with their state-of-the-art adaptive optics system, called GeMS. An acronym for Gemini Multi-conjugate adaptive optics System, GeMS allows scientists at the observatory to capture deep-space images without the usual distortions created by Earth's atmosphere. "What we have seen so far signals an incredible capability that leaps...

Gemini Observatory Has New Instrument To Study Universe With Such Clarity, Detail
2013-01-10 12:45:37

redOrbit Staff & Wire Reports - Your Universe Online Researchers at the Gemini Observatory in Chile are touting a new instrument that they claim will allow astronomers to “study the universe with an unprecedented level of clarity and detail.” The system is called GeMS, and it is an advanced adaptive optics system that has been installed on the Gemini South telescope. According to a statement released by representatives of the facility on Wednesday, it is the first...

Physicists propose beaming laser at atmospheric sodium to measure global magnetic field Mapping the Earth's magnetic field "“ to find oil, track storms or probe the planet's interior "“ typically requires expensive satellites. University of California, Berkeley, physicists have now come up with a much cheaper way to measure the Earth's magnetic field using only a ground-based laser. The method involves exciting sodium atoms in a layer 90 kilometers above the surface and measuring...

Laser Guide Star System on ESO's VLT Starts Regular Science Operations An artificial, laser-fed star now shines regularly over the sky of Paranal, home of ESO's Very Large Telescope, one of the world's most advanced large ground-based telescopes. This system provides assistance for the adaptive optics instruments on the VLT and so allows astronomers to obtain images free from the blurring effect of the atmosphere, regardless of the brightness and the location on the sky of the observed...

First Light for the VLT Laser Guide Star Facility ESO -- Scientists celebrate another major milestone at Cerro Paranal in Chile, home of ESO's Very Large Telescope array. Thanks to their dedicated efforts, they were able to create the first artificial star in the Southern Hemisphere, allowing astronomers to study the Universe in the finest detail. This artificial laser guide star makes it possible to apply adaptive optics systems, that counteract the blurring effect of the atmosphere, almost...
