The Arecibo Observatory's telescope has collapsed
The world-famous Arecibo Observatory has collapsed.
Arecibo Observatory will be torn down because repairs are too dangerous
After 57 years of helping to expand human knowledge and understanding of the cosmos, the story of Puerto Rico’s world-famous Arecibo Observatory is coming to an unfortunate end.
Puerto Rico’s Arecibo radio telescope suffers serious damage
A broken cable damaged the Arecibo Observatory, the second-largest radio telescope in the world.
NASA's Chandra telescope follows Hubble into a shutdown
NASA sure hasn't been having a great time with its telescopes. The Chandra X-ray Observatory has gone into safe mode and halted all its science operations a few days after Hubble shut down due a gyroscope failure. According to the agency, Chandra's transition into safe mode was possibly triggered by an issue that also has something to do with its gyroscope, the component in charge of pointing and stabilizing the telescope.
Hurricane Maria wreaks havoc on Arecibo radio telescope
Puerto Rico is suffering on an unimaginable scale in the wake of Hurricane Maria. Many have been displaced from their homes, and the entire territory may go without electricity and reliable communication for months. And while the human tragedy is clearly the most important concern, it's also having a terrible effect on the scientific community. Researchers have learned that the Arecibo Observatory and its signature radio telescope took significant damage when the hurricane passed over. All staff members are thankfully safe for now, but an atmospheric radar line feed and a 39-foot dish (used for Very Long Baseline Interferometry) were lost in winds that reached up to 155MPH. The gigantic central dish is intact, although the line feed's collapse punctured it in places.
Earth's orbiting observatories and their literally awesome images
While the Voyager 1 probe, launched in 1977, cruises into interstellar space (the farthest man-made object from Earth) and missions like New Horizons capture snaps from the outskirts of the solar system, we've been keeping the heavy hitters close to home. Massive space telescopes that scan the cosmos with augmented eyes have been orbiting the Earth for years to get a clear view of the universe without atmospheric distortion. The Hubble Space Telescope's 1990 launch set a new precedent for these space-based observatories in terms of scale and abilities. These new instruments have helped scientists gather an incredible amount of data and mind-bending photos from deep space. With Pluto hogging the spotlight lately, we decided to take a look back at some of these powerful orbiting eyes and their visual achievements. [Image credit: JPL]
Radio telescope array could unlock the secrets of the early universe
To capture the night sky and better understand the formative years of our universe, astronomers are using something a tad more powerful than a traditional telescope. The Owens Valley Long Wavelength Array (OV-LWA) leverages 250 radio antennas, spread over a desert area equivalent to 450 football fields, to detect slender radio signals produced by distant pulsars, solar flares and auroras. Together, this army of antennas can capture the entire sky simultaneously and feed the resulting data back to the Owens Valley Radio Observatory. With over 25 terabytes flowing in every day, astronomers can study space weather, such as auroras, which occur when stars release magnetic energy.
VLT Survey Telescope snaps out-of-this-world photos with 268-megapixel camera
The European Southern Observatory (ESO) has just released the first batch of shots taken by its VLT Survey Telescope (VST), and, given the results, we'd say the thing's got a bright future in photography. Not to be mistaken for its cousin, the VLT (very large telescope), the VST sports a 268-megapixel camera, known as the OmegaCAM, and a field of view "twice as broad as the full moon." The images released by the ESO feature the Omega Nebula (located in the Sagittarius constellation) and Omega Centauri in stellar detail. Annie Lebovitz, eat your heart out -- the rest of you hop on past the break for another shot by this up and coming shutterbug.
