An activist claims the smog now blanketing greater Bangkok comes from farmers burning sugarcane fields to make harvesting easier. Public discontent has surfaced on Thai social media, with pollution-related hashtags trending. The Thaiger publishes national air quality readings daily. In recent weeks, municipal workers have sprayed water along the roads and into the air in Bangkok to help clear the smog, while authorities have urged people to stay indoors.

    The Most Famous Photo of Planet Earth Turns 50 on Christmas Eve

    Science

    That led NASA planners to abandon their step-by-step plan and consider sending Apollo 8's astronauts - Anders, Jim Lovell and mission commander Frank Borman - on their own round-the-moon trip. The first Earth Day was marked in the USA just over a year later, in April 1970, while the founding of environmental organisations such as Greenpeace wasn't far behind.

    The rocket, which was carrying a satellite worth roughly $500m (£393.7m) built by Lockheed Martin , blasted off from Florida just before 2pm GMT. Hawthorne-based SpaceX Sunday successfully launched a U.S. It would mark SpaceX's first so-called National Security Space mission, as defined by the USA military, SpaceX said. The Air Force said that the launch was originally scheduled for 2014 but has been hobbled by production delays.

    Winter solstice: Why is it the shortest day of the year?

    Science

    That precise instant in time - in 2018, at 5:23 p.m. EST on December 21 - is the solstice. In the southern hemisphere it's exactly the opposite story - the South Pole is pointing towards the Sun, making it summertime "down-under". There will be a winter trifecta the next few days with the winter solstice, a full moon and a meteor shower. In addition, even as the days get longer, the oceans, which moderate temperatures on land, need a vast amount of energy from the sun to heat up.

    They found that this was due to water molecules in the icy rings becoming electrically charged, either by interaction with ultraviolet radiation from the Sun, or by meteoroid bombardment, and that the water was then being caught up in Saturn's magnetic field, and dragged down into the planet's atmosphere by gravity.

    Virgin Galactic's spacecraft Unity was piloted by two veteran pilots: Mark "Forger" Stucky and Rick "CJ" Sturckow. SpaceShipTwo, VSS Unity, took off in the early morning sunshine at the Mojave test centre in California on Thursday in front of hundreds of employees and their family members.

    Geminid meteor shower reaches its peak Thursday night

    Science

    That means that the best times to watch are when it's dark in your local time zone surrounding that peak, such as just before dawn on December 14. But we suggest you turn off your screens and get outside to one of these Geminids viewing events around the Bay Area. The darker your sky, the better, though you don't have to leave the city to see the brighter ones.

The spacecraft sits in what appears to be a almost rock-free "hollow" - a depression created by a meteor impact that later filled with sand. InSight will dig some 16 feet (five meters) below where it is situated with its heat-flow-probe.

    Don't miss the Geminids tonight!

    Science

    The Geminid meteor shower gets its name from its proximity to the constellation Gemini's namesake stars, Castor and Pollux the Gemini twins. Space.com columnist Joe Rao agreed, citing in his column the nice timing of this year's Geminids : the crescent moon will set around 10:30 p.m.

    Crew members used tape to cover the hole and experts speculated that it could have been caused by the impact of a high-speed rocky fragment flying through space. Kononenko used a pair of forceps and a swab to collect samples of the dark epoxy. "The active participation of worldwide partners, primarily NASA, in the investigation is not expected, although we have called for a joint investigation and been ready to provide available materials: photos, videos, documents, samples of materials ...
