    Washington Post ^ | 9/21/17 | Sarah Kaplan
    The National Science Foundation has not heard from staff at the iconic Arecibo Observatory in Puerto Rico since Hurricane Maria roared over the island. A spokeswoman for NSF, which owns the observatory, said the agency hadn't received any official communications from Arecibo since 8 a.m. Wednesday — before the eye of the storm passed over the telescope. Two of the groups that helps manage the observatory, SRI International and the Universities Space Research Association, also hadn't heard from their staff on site. One observatory staff member who weathered the storm in the town of Arecibo contacted the association via shortwave...

    Spat over design of new Chinese telescope goes public By Yongming HuangAug. 11, 2017 , 12:13 PM A deep division among Chinese astronomers over the design of a proposed 12-meter telescope broke into public view this week as statements from competing camps went viral on social media. The dispute centers on whether to adopt a technically ambitious four-mirror design proposed by optical engineers or a conventional three-mirror option favored by astronomers. The stakes are high. It will be China’s largest optical telescope and serve as the workhorse observational facility for several generations. In a 4 August letter to the Chinese...

    Set to be launched in 2018 from Kourou, French Guiana, the JWST will embark on a journey to unravel the universe’s mysteries, "from discovering the first stars and galaxies" to "studying the atmospheres of alien planets around other stars." “This was the first time all the different parts worked together at the same time, and this was the first time it was tested against the actual spacecraft flight hardware,” explained Alan Johns, ground segment and operations manager for the Webb telescope at NASA’s Goddard Space Flight Center. NASA called, and the Webb telescope responded. NASA’s James Webb Space Telescope recently...

    The discovery of seven habitable planets just 40 light years away is certainly impressive, but the fact is, they are still 40 light years away. Unless we're willing and able to spend thousands of years traveling through space, we won't be rolling into the TRAPPIST-1 system anytime soon. This means that over the coming decades, advanced scientific instruments closer to home will play very important roles in exploring these distant worlds – perhaps none more so than the James Webb Space Telescope. So what can we expect when it is fired into orbit next year? We checked in with some...

    BBC ^ | 9/14/16 | Jonathan Amos
    The most precise map of the night sky ever assembled is taking shape. Astronomers working on the Gaia space telescope have released a first tranche of data recording the position and brightness of over a billion stars. And for some two million of these objects, their distance and sideways motion across the heavens has also been accurately plotted. Gaia's mapping effort is already unprecedented in scale, but it still has several years to run. Remarkably, scientists say the store of information even now is too big for them to sift, and they are appealing for the public's help in making...

    Explanation: Seen any planets lately? All three planets now shining brightly in the night sky are imaged in these panels, captured last week with the 1 meter telescope at Pic du Midi Observatory in the French Pyrenees. Near opposition and closest to Earth on May 30, Mars is presently offering the best ground-based photo-ops in the last decade. The sharp image finds clouds above the Red Planet's north pole (top) and towering volcanos near its right limb. Saturn reaches its own opposition tonight, its bright rings and gaps clearly revealed in the telescopic portrait. Jupiter is currently highest during the...

    Explanation: How did the universe evolve from such a smooth beginning? To help understand, computational cosmologists and NASA produced the featured time-lapse animated video depicting a computer simulation of part of the universe. The 100-million light-year simulation starts about 20 million years after the Big Bang and runs until the present. After a smooth beginning, gravity causes clumps of matter to form into galaxies which immediately begin falling toward each other. Soon, many of them condense into long filaments while others violently merge into a huge and hot cluster of galaxies. Investigating of potential universe attributes in simulations like this...

    Explanation: Move over Hubble -- here comes the James Webb Space Telescope (JWST). JWST promises to be the new most powerful telescope in space. In the last month, the 18-segment gold-plated primary mirror for JWST was unveiled. In the featured time-lapse video taken last week, the 6.5-meter diameter mirror was raised to a vertical position. The dramatic 30-second sequence shows NASA engineers monitoring the test as room lights glint brightly off the mirror's highly reflective surface. The beryllium mirrors have been coated with a thin film of gold to make them more reflective to infrared light. The science goals of...
  • Japan Loses Contact With New Space Telescope

    03/27/2016 5:24:14 PM PDT · by BenLurkin · 37 replies
    On Saturday, Japan lost contact with its newest space telescope, called Hitomi or ASTRO-H. The telescope, which includes an instrument from NASA, was intended to study the high-energy universe in X-rays and gamma rays, and observe such objects as supermassive black holes and galaxy clusters. Radar observations Sunday indicated that Hitomi, which launched on February 17, is in at least five pieces—and a plot of its orbit revealed a dramatic change on March 26, the date JAXA lost contact with the spacecraft. That means, says astrophysicist Jonathan McDowell, that some kind of “energetic event” has occurred—something more than a simple...

    The Ariane 5 rocket is a workhorse for delivering satellites and other payloads into orbit, but fitting the James Webb Space Telescope (JWST) inside one is pushing the boundaries of the Ariane 5’s capabilities, and advancing our design of space observatories at the same time. The Ariane 5 is the most modern design in the ESA’s Ariane rocket series. It’s responsible for delivering things like Rosetta, the Herschel Space Observatory, and the Planck Observatory into space. The ESA is supplying an Ariane 5 to the JWST mission, and with the planned launch date for that mission less than three years...
  • Astronomers say real-life 'death star' destroying faraway rocky object

    CAPE CANAVERAL, Fla. – A white dwarf star in the Constellation Virgo turns out to be a "death star" worthy of "Star Wars." Astronomers announced Wednesday that they have discovered a rocky object coming apart in a death spiral around this distant star. They used NASA's exoplanet-hunting Kepler spacecraft to make the discovery, then followed up with ground observations. "This is something no human has seen before," said Andrew Vanderburg of the Harvard-Smithsonian Center for Astrophysics in Cambridge, Massachusetts, the lead author. "We're watching a solar system get destroyed," he said in a statement.

Stopping construction would be key, he said. "You can't even get to the discussion point until they stop construction," he said. ...

    Phys.Org ^ | Jan 16, 2015 | Provided by University of Arizona
    NASA's Kepler Space Telescope, despite being hobbled by the loss of critical guidance systems, has discovered a star with three planets only slightly larger than Earth. The outermost planet orbits in the "Goldilocks" zone, a region where surface temperatures could be moderate enough for liquid water and perhaps life, to exist. The star, EPIC 201367065, is a cool red M-dwarf about half the size and mass of our own sun. At a distance of 150 light years, the star ranks among the top 10 nearest stars known to have transiting planets. The star's proximity means it's bright enough for astronomers...

    The Kepler space telescope has spotted over 1,000 exoplanets beyond our solar system, and its latest finds are three almost Earth-sized planets, including one in the habitable zone circling the star EPIC 201367075, just 150 light years from Earth. In the cosmic sense, that’s right around the block, making it one of the 10 closest known stars with observed planets in its gravitational hold. Of course, such distances in the cosmic sense also would take many generations to traverse, so don’t invest in real estate there just yet. Still, the relative closeness of this “EPIC” star and its planets provides...

    Inside a very big and very clean room at NASA’s Goddard Space Flight Center in Greenbelt, Md., nearly 30 workers dressed in white protective suits, goggles and blue booties cluster around the parts of a time machine. These parts — gold-covered mirrors, tennis-court-size sun shields, delicate infrared cameras — are slowly being put together to become the James Webb Space Telescope.
