    Japan launched seven spacecraft to Earth orbit today (Jan. 17), including a little satellite designed to create dazzling artificial meteor showers. The primary payload on today's launch was the Rapid Innovative Payload Demonstration Satellite 1 (RAPIS-1), whose boxy body measures about 3.3 feet (1 meter) on a side. In a first for JAXA, the agency consigned the manufacture and operation of RAPIS-1 to a startup — the Japanese company Axelspace. RAPIS-1 carries a variety of technology demonstrations, including a thin-membrane, paddle-shaped solar array; small thrusters that use low-toxicity propellant; a low-cost particle sensor; and "deep-learning" software that will aid attitude...

    Russian startup wants to put ads in low-Earth orbit to ruin the sky for everybody January 16, 2019Will there be no end to people trying to muck up the night sky? Around this time last year it was a disco ball sent into low-Earth orbit. Now a Russian startup has had the colossally dense idea of sticking beaming billboards up there, to shine advertising back down to Earth.Putting aside the fact that advertising is already ubiquitous, the notion of adding a significant source of light pollution to the night sky has astronomers – professional and amateur alike – fuming.The...

    CAPE CANAVERAL, Fla. (AP) — Here comes a total lunar eclipse and supermoon, all wrapped into one. The moon, Earth and sun will line up this weekend for the only total lunar eclipse this year and next. At the same time, the moon will be ever so closer to Earth and appear slightly bigger and brighter than usual — a supermoon. "This one is particularly good," said Rice University astrophysicist Patrick Hartigan. "It not only is a supermoon and it's a total eclipse, but the total eclipse also lasts pretty long. It's about an hour." The whole eclipse starts Sunday...

    The NROL-71 spacecraft is scheduled to launch atop a United Launch Alliance (ULA) Delta IV Heavy rocket from California's Vandenberg Air Force Base on Saturday (Jan. 19) at 2:05 p.m. EST (1905 GMT; 11:05 a.m. local California time), ULA representatives announced yesterday (Jan. 15). ULA had originally targeted early December for NROL-71's liftoff, but bad weather and technical issues pushed the launch back multiple times. The most recent attempt, on Dec. 19, was nixed because of a slight hydrogen leak on the Delta IV Heavy — an issue that has taken several weeks to resolve. NROL-71 will be operated by...

    The most distant object humanity has ever visited looks something like a spinning snowman or hourglass that’s lost in space.Researchers who work on NASA’s nuclear-powered New Horizons mission released a movie on Tuesday showing the rotation of the mountain-size rock, which is known formally as (486958) 2014 MU69.(It’s more commonly referred to as “Ultima Thule”.)Mu69 is about 4 billion miles (6 billion kilometres) from Earth and 1 billion miles (2 billion kilometres) beyond Pluto.New Horizons flew by the object on New Year’s Day at a speed of 32,200 miles per hour (52,000 kilometres per hour), and came within about 2,200 miles...

    Messier 100, also known as M100, NGC 4321 and LEDA 40153, is located approximately 50 million light-years away in the constellation of Coma Berenices.This galaxy is one of the brightest members of the Virgo Cluster, a group of about 1,300 (and possibly up to 2,000) galaxies.Its apparent magnitude of 10.1 means that, while it can be seen through small telescopes, it will appear only as a faint patch of light. Larger telescopes can resolve more details of the galaxy.The galaxy was discovered on March 15, 1781 by the French astronomer Pierre Méchain, Charles Messier’s fellow comet hunter who discovered eight...
  • Weird star system has double binary stars and wonky planetary nursery

    There is a star system 146 light years from Earth that is quite strange. At its centre is a set of binary stars, and around that loops another binary pair. In between is a ring of dust and gas that’s set at a very odd angle. The dust and gas of this system, which is called HD 98800, are part of a disc that may be forming planets in a kind of cosmic nursery. Instead of lying on the same plane as the central stars, this disc’s orbit is perpendicular to that. The full system is even more confusing (see...

    God in Winter: Pondering the Gift of Snow Msgr. Charles Pope • January 13, 2019 • It snowed yesterday in Washington, D.C. It wasn’t anything epic, just a decent six-incher. There were drawbacks, of course: Mass attendance was poor, and I had to get up early to shovel a path to the doors. (Thank you, Lord, for the helpers you sent!) Despite the inconvenience, snow incites wonder and awe in me. I realize that not everyone likes snow, but it is an amazing work of God. He takes a barren winter landscape and creates it anew. I can almost hear...

    The floor of the Gulf of Mexico is one of the most geologically interesting stretches of the Earth’s surface. The gulf’s peculiar history gave rise to a landscape riddled with domes, pockmarks, canyons, faults, and channels — all revealed in more detail than ever before by a new 1.4 billion-pixel map. This striking view of the ocean floor off the coasts of Louisiana and Texas was created by a government agency you’ve likely never heard of called the Bureau of Ocean Energy Management (BOEM). The bureau’s job is to manage exploration and development of the country’s offshore mineral and energy...

    Dr. Tremblay said: "This is the first direct evidence that white dwarfs crystallise, or transition from liquid to solid. It was predicted fifty years ago that we should observe a pile-up in the number of white dwarfs at certain luminosities and colours due to crystallisation and only now this has been observed....The Sun itself will become a crystal white dwarf in about 10 billion years."

    BBC ^ | 9 January 2019 | By Helen Briggs
    Astronomers have revealed details of mysterious signals emanating from a distant galaxy, picked up by a telescope in Canada. The precise nature and origin of the blasts of radio waves is unknown. Among the 13 fast radio bursts, known as FRBs, was a very unusual repeating signal, coming from the same source about 1.5 billion light years away. Such an event has only been reported once before, by a different telescope. "Knowing that there is another suggests that there could be more out there," said Ingrid Stairs, an astrophysicist from the University of British Columbia (UBC). "And with more repeaters...

    scientificamerican ^ | January 8, 2019 | Alexandra Witze, Nature magazine
    First spotted in 2007, FRBs are one of the most intriguing mysteries in astrophysics. They appear all over the sky, and astronomers aren’t sure what causes them. n early testing during July and August, before it began full operations, CHIME spotted 13 FRBs. Prior to this, astronomers had between 50 and 60 examples. The more FRBs that astronomers find, the greater the chance they can start to pin down their origin. CHIME also detected only the second known FRB that repeats, meaning that the radio flashes re-appear at the same point in the sky. It saw the repeater pop up...

    Extraordinary Claims Need an Extraordinary Cosmos. Today the thoughtful scientist finds himself embroiled in an internal war between his devotion to naturalism and his realization that the universe is, as physicist Steven Weinberg put it, "one fine-tuning that seems to be extreme, far beyond what you could imagine just having to accept as a mere accident." ...The latest explanation, trotted out by Columbia astrophysicist Caleb Scharf, is that an early, advanced, non-biological civilization "decided to tinker with the expansion" of the universe in a way that made it amenable to the evolution of biological life.

    The goal of education has always been to achieve critical thinking. Needless to say, this involves a two-step process: first, students learn a great deal about a topic, whether in history, science, art, or anything else; then students learn to arrange the information in new ways, to set one fact against another, to find new insights among this knowledge. Not anymore. Today's educators are in a hurry; they don't bother with the first step. They jump directly to step two. In this scenario, students who know nothing are expected to talk intelligently about it. What absurdity.Having just heard about X,...

    The problem with science is that so much of it simply isn’t by John Hartnett In the opening sentence in an article titled “Scientific Regress”, the author William Wilson remarks: “Scientific claims rest on the idea that experiments repeated under nearly identical conditions ought to yield approximately the same results, but until very recently, very few had bothered to check in a systematic way whether this was actually the case.”1 The article is about science and the repeatability of scientific results published in the peer-reviewed scientific literature.

    Neuroscientists have successfully hooked up a three-way brain connection to allow three people to share their thoughts – and in this case, play a Tetris-style game. The team thinks this wild experiment could be scaled up to connect whole networks of people, and yes, it's as weird as it sounds. It works through a combination of electroencephalograms (EEGs), for recording the electrical impulses that indicate brain activity, and transcranial magnetic stimulation (TMS), where neurons are stimulated using magnetic fields. The researchers behind the system have dubbed it BrainNet, and say it could eventually be used to connect many different minds...

    KTLA ^ | 01/01/2018
    Although the flyby occurred at 12:33 a.m. ET on Tuesday, the spacecraft is so far from Earth that the “phone-home” signal didn’t reach us until about 10:30 a.m. ET. Mission scientists were relieved about the success because there was only one chance to get it right as New Horizons screamed past Ultima at 31,500 miles per hour. This incredible feat was possible because thousands of operations on the spacecraft worked in sync. “We’ve just accomplished the most distant flyby,” mission operations manager Alice Bowman said. “This science will help us understand the origins of our solar system.” New Horizons has...
