    NASA's beloved Hubble Space Telescope has been facing one of its greatest challenges. A technical glitch left it in safe mode for over a month. This week, NASA said it finally tracked down the source of the issue and tried a new fix, and it seems to have worked. "NASA has successfully switched to backup hardware on the Hubble Space Telescope, including powering on the backup payload computer, on July 15," the space agency announced on Friday. The telescope has been in service for over 30 years. The Hubble team had been looking at the payload computer -- hardware dating...

    Posted on June 15, 2021June 15, 2021 by Evan GoughNASA has Approved a Space Telescope That Will Scan the Skies for Dangerous Near-Earth AsteroidsA lot of the threats humanity faces come from ourselves. If we were listing them, we’d include tribalism, greed, and the fact that we’re evolved primates, and our brains have a lot in common with animal brains. Our animalistic brains subject us to many of the same destructive emotions and impulses that animals are subject to. We wage war and become embroiled in intergenerational conflicts. There are genocides, pogroms, doomed boatloads of migrants, and horrible mashups of...

    After my recent move to Arizona I am amazed at the night time sky. I am now looking for a decent telescope to study the Messier objects, planets and such. It appears that there are some great buys below $2,000 in the Schmidt Cassegrain field, even some Macs. Does anybody have any information they can give on this? I had an old 8" Newtonian, which was a royal pain to take anywhere.

    Apr 7, 2021NASA’s Webb Telescope Packs Its Sunshield for a Million Mile TripEngineers working on NASA’s James Webb Space Telescope have successfully folded and packed its sunshield for its upcoming million-mile (roughly 1.5 million kilometer) journey, which begins later this year.The sunshield — a five-layer, diamond-shaped structure the size of a tennis court — was specially engineered to fold up around the two sides of the telescope and fit within the confines of its launch vehicle, the Ariane 5 rocket. Now that folding has been completed at Northrop Grumman in Redondo Beach, California, the sunshield will remain in this compact...

    Futurism ^ | 03/12/2021 | Victor Tangermann
    The massive space telescope, featuring a 21 foot mirror, and a tennis court-sized protective cage, is far too large to stick inside a plane. Instead, NASA will have to ship the massive mirror right through the Panama Canal for its eventual launch in French Guiana — and NASA is worried that the journey could attract robbers. The shipping time and location will be hush-hush to ward off any extremely ambitious thieves. All we know is that it will sail off in late summer. It’s an especially harrowing sea passage for a project that has been going on for over two...
  • Hubble Space Telescope is back online after software glitch

    The venerable Hubble Space Telescope is recovering from a glitch that halted its science operations over the weekend, according to NASA. The telescope entered "safe mode" unexpectedly on Sunday morning (March 7), stalling the observatory's science observations due to an apparent software glitch. Science operations resumed late Thursday (March 11). While Hubble is partially back to work, NASA is still troubleshooting one instrument on the 30-year-old telescope, according to a statement released on Friday (Mar. 12). The WFC3 issue was an "unexpected error," according to NASA, that occurred when the telescope was transitioning from safe mode into pre-science after the...

    THE Hubble space telescope has been taken offline with all observations halted until further notice. The Nasa team behind the $1.5billion contraption said that it was placed into "safe mode" at 4pm ET (9pm GMT) on Sunday due to a software bug. The telescope, which orbits about 547 kilometers (340 miles) above Earth, is not in danger of shutting down permanently, according to the official Hubble Twitter account. "All science systems appear normal and Hubble is safe and stable," the account tweeted on Monday. "The team is working [on] plans to safely return it to normal science operations." Launched in...

    Are you ready for one of “the great scientific adventures of the coming decades”? Construction of the largest and most complex radio telescope network in the world officially began today in what is being described as a “historic moment for radio astronomy.” Designed to help astronomers answer some of astronomy’s most fundamental questions, the Square Kilometre Array Observatory (SKAO) was today given the go-ahead at its first council meeting at its headquarters at Jodrell Bank, Cheshire in the UK. Jodrell Bank is home to the Lovell Telescope, the world’s third-largest steerable radio telescope. SKA is going to cost $2.2 billion—and...

    The National Science Foundation announced Thursday that it will close the huge telescope at the renowned Arecibo Observatory in Puerto Rico in a blow to scientists worldwide who depend on it to search for planets, asteroids and extraterrestrial life. The independent, federally funded agency said it’s too dangerous to keep operating the single dish radio telescope — one of the world’s largest — given the significant damage it recently sustained. An auxiliary cable broke in August and tore a 100-foot hole in the reflector dish and damaged the dome above it. Then on Nov. 6, one of the telescope’s main...

    New simulations show that NASA’s Nancy Grace Roman Space Telescope will be able to reveal myriad rogue planets – freely floating bodies that drift through our galaxy untethered to a star. Studying these island worlds will help us understand more about how planetary systems form, evolve, and break apart. Astronomers discovered planets beyond our solar system, known as exoplanets, in the 1990s. We quickly went from knowing of only our own planetary system to realizing that planets likely outnumber the hundreds of billions of stars in our galaxy. Now, a team of scientists is finding ways to improve our understanding...

    At Arecibo, scientists conduct all sorts of work, from atmospheric and planetary science through to radio and radar astronomy and even searches for extraterrestrial intelligence, also known as SETI. The purpose of these observations are to determine the ways in which red dwarf stars, like Barnard’s Star, affect the habitability of their planets. Méndez was also planning to embark on a SETI project to detect extraterrestrial technosignatures (i.e. evidence of alien technology), which would have leveraged both past and future observations at Arecibo. All this now appears to be on hold. Méndez’s observations aren’t time critical, but others might be,...

    LCRT would be an ultra-long-wavelength radio telescope capable of capturing some of the weakest signals traveling through space. “It is not possible to observe the universe at wavelengths greater than 10 meters [33 feet], or frequencies below 30 MHz, from Earth-based stations, because these signals are reflected by the Earth’s ionosphere,” said Bandyopadhyay. “Moreover, Earth-orbiting satellites would pick up significant noise from Earth’s ionosphere,” which is why “such observations are very difficult.” It’s for this reason that wavelengths greater than 10 meters have yet to be explored by scientists. Consequently, this telescope would be a tremendous boon to astronomers and...

    Astronomers have discovered that the planet Uranus has a blue ring - only the second found in the Solar System. Like the blue ring of Saturn, it probably owes its existence to an accompanying small moon. Scientists suspect subtle forces acting on dust in the rings allow smaller particles to persist while larger ones are recaptured by the moon. Smaller particles reflect blue light, giving the ring its distinctive colour, the US team reports in Science. All other rings - those around Jupiter, Saturn, Uranus and Neptune - are made up of both large and small particles, making the...

    Galaxy clusters are cosmic structures containing hundreds or even thousands of galaxies. Multi-million-degree gas fills the space in between the individual galaxies. The mass of the hot gas is about six times greater than that of all the galaxies combined.This superheated gas is invisible to optical telescopes, but shines brightly in X-rays, so an X-ray telescope like Chandra is required to study it.By combining X-rays with other types of light, such as radio waves, a more complete picture of these important cosmic objects can be obtained.Using X-ray and radio data, a team of astronomers led by Leiden Observatory’s Dr. Francesco...
