    It will be quite a sight as the earth's shadow is cast over the moon creating a orange/reddish color. The good news is that skies will be completely clear, but temps will be very cold for standing out to view! The earth will pass directly between the moon and the sun on Sunday night Jan 20-21, creating the total lunar eclipse. It will begin at 10:34PM as the shadow begins to infringe upon the lower side of the moon. You'll see the start of the total eclipse happen around 11:41PM, and the peak total eclipse will be at 12:12AM Monday...

    One Russian company has announced a plan to build gigantic billboards in space, lighting up the night sky with advertisements for companies like Coke, McDonald’s, and KFC. If they’re successful, we could start seeing advertisements floating in the sky as soon as 2021. On the one hand, this is a pretty incredible technological marvel. The company, StartRocket, plans to launch dozens of tiny CubeSats into orbit roughly 280 miles above the ground in a single rocket. Those CubeSats would then fly in formation and deploy giant reflective sails to send the Sun’s light to the Earth. Each one of these...
  • Asteroids have been crushing Earth for nearly 300 million years and no one knows why

    Asteroids have been hitting the Earth for nearly 1 billion years, but the atmosphere has largely shielded the planet from some catastrophic events. However, some space rocks make their way through — including the one that wiped out the dinosaurs. But a new study notes that, over the past 290 million years, asteroids have been impacting the Earth at triple the rate they were previously and scientists aren't sure why. After looking at 1 billion years' worth of asteroid impacts on both the Earth and Moon, researchers found that dinosaurs' fate was perhaps an inevitability.

    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...

    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...

    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...

    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...

    The spacecraft that have peered through the yellowish haze surrounding Saturn's moon Titan discovered a strange, yet strangely familiar world where life could theoretically take root. Now, scientists want to return — this time buoyed by Earth's fascination with drone technology. That's precisely what a team of scientists working on a proposed mission called Dragonfly want to do: combine terrestrial drone technology and instruments honed by Mars exploration to investigate the complex chemical reactions taking place on Saturn's largest moon. Later this year, NASA will need to decide between that mission and another finalist proposal, which would collect a sample...

    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...

    China has declared its latest moon mission a success, hailing it as a landmark in its quest to become a strong space power by 2030. The country’s Chang’e-4 probe, named after a moon goddess of Chinese legend, was the world’s first spacecraft to land on the far side of the moon, which is not visible from the Earth. The landing on January 3 was the latest leap for Beijing as it tries to catch up with the United States in space. The Chang’e-4 mission did not stop with the historic landing. Here are five other things China’s moon probe has...

    The telescope could not recognize instructions from the control center but is still sending data back to Earth, according to Nikolai Kardashev, director of the Astro Space Center of the Physical Institute of the Russian Academy of Sciences. "Now there are attempts to fix the situation ... There are various systems of communication there, some of which are operating and some are not ... Such failures have already happened. Everything may operate again. We hope for that," Kardashev was quoted by Sputnik news agency as saying. The Spektr-R telescope was launched in 2011

    Astronomers know our solar system better than any other, but they're still learning new ways in which it doesn't seem to be particularly normal. Right now, the leading theory of planetary formation, called the "core accretion model," is tailored to explain what we see in our solar system — the only one we knew much of anything about when the model was developed. But the more planets we identify in other solar systems, the more we find they don't match the patterns of mass and orbital distances found here on our own. Take, for example, the staggering size gap between...

    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."

    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...

    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...
