    Seeing our world through the eyes of a migratory bird would be a rather spooky experience. Something about their visual system allows them to 'see' our planet's magnetic field, a clever trick of quantum physics, and biochemistry that helps them navigate vast distances. Now, for the first time ever, scientists from the University of Tokyo have directly observed a key reaction hypothesised to be behind birds', and many other creatures', talents for sensing the direction of the planet's poles. Importantly, this is evidence of quantum physics directly affecting a biochemical reaction in a cell – something we've long hypothesised but...

    Explanation: Barred spiral galaxy NGC 1365 is truly a majestic island universe some 200,000 light-years across. Located a mere 60 million light-years away toward the chemical constellation Fornax, NGC 1365 is a dominant member of the well-studied Fornax Cluster of galaxies. This impressively sharp color image shows the intense, reddish star forming regions near the ends of central bar and along the spiral arms, with details of the obscuring dust lanes cutting across the galaxy's bright core. At the core lies a supermassive black hole. Astronomers think NGC 1365's prominent bar plays a crucial role in the galaxy's evolution, drawing...
  • Hidden Symmetry Could Be Key to Ultra-Powerful Quantum Computers

    Researchers have found a way to protect highly fragile quantum systems from noise, which could aid in the design and development of new quantum devices, such as ultra-powerful quantum computers. The researchers, from the University of Cambridge, have shown that microscopic particles can remain intrinsically linked, or entangled, over long distances even if there are random disruptions between them. Using the mathematics of quantum theory, they discovered a simple setup where entangled particles can be prepared and stabilized even in the presence of noise by taking advantage of a previously unknown symmetry in quantum systems. Their results, reported in the...
  • Rare Mercury, Jupiter, and Saturn ‘triple conjunction’ to light up sky this weekend

    KTLA ^ | 01/07/2021
    From Jan. 9-12, Mercury, Jupiter, and Saturn will be visible in the southwestern sky. The celestial event is known as a “triple conjunction,” which means two planets and a third planet meet each other in the sky for a short period of time. Shortly after sunset on Jan. 9, look above the west-southwestern horizon and you will see Mercury to the left of Saturn and Jupiter positioned just above Saturn. “From Friday evening to Monday evening, the planet Mercury will appear to pass first by Saturn and then by Jupiter as it shifts away from the horizon, visible each evening...

    The largest black holes in the universe... sit at the centers of almost every galaxy in the cosmos. Even the Milky Way has one, a monster at 4 million solar masses, designated as Sagittarius A*. ...[A]s far as we know, the only way to form black holes is through the deaths of massive stars. When they die, they leave behind a black hole a few times more massive than the sun. To get to supergiant status, they have to merge with other black holes and/or consume as much gas as possible, bulking up all those millions of solar masses... Either...
  • Astronomy Picture of the Day - Striped Sand Dunes on Mars

    APOD.NASA.gov ^ | 6 Jan, 2021 | Image Credit: HiRISE, MRO, LPL (U. Arizona), NASA; Processing: Włodek Głażewski; Text: Alex R. Howe
    Explanation: Why are these sand dunes on Mars striped? No one is sure. The featured image shows striped dunes in Kunowsky Crater on Mars, photographed recently with the Mars Reconnaissance Orbiter’s HiRISE Camera. Many Martian dunes are known to be covered unevenly with carbon dioxide (dry ice) frost, creating patterns of light and dark areas. Carbon dioxide doesn’t melt, but sublimates, turning directly into a gas. Carbon dioxide is also a greenhouse material even as a solid, so it can trap heat under the ice and sublimate from the bottom up, causing geyser-like eruptions. During Martian spring, these eruptions can...

    We'll be able to have more productive and honest conversations with one another the sooner we realize that while morality takes sides, science does not.Even as coronavirus vaccines slowly make their way into the population, debates rage around the world on whether lockdowns should continue or be implemented anew. Often in these debates, one hears the term “science” tossed about irresponsibly, sometimes by participants on both sides of the argument.Most of the time, however, when people say that we should “follow the science,” they mean we should listen to the expert advice of medical professionals who argue in favor of...
  • Researchers achieve sustained, high-fidelity quantum teleportation

    Phys.org ^ | December 29, 2020 | University of Chicago
    Quantum teleportation is a "disembodied" transfer of quantum states from one location to another. The quantum teleportation of a qubit is achieved using quantum entanglement, in which two or more particles are inextricably linked to each other. If an entangled pair of particles is shared between two separate locations, no matter the distance between them, the encoded information is teleported. In a paper published in PRX Quantum, the team presents for the first time a demonstration of a sustained, long-distance teleportation of qubits made of photons (particles of light) with fidelity greater than 90%. The qubits were teleported over a...

    Explanation: In the mid 19th century, one of the first photographic technologies used to record the lunar surface was the wet-plate collodion process, notably employed by British astronomer Warren De la Rue. To capture an image, a thick, transparent mixture was used to coat a glass plate, sensitized with silver nitrate, exposed at the telescope, and then developed to create a negative image on the plate. To maintain photographic sensitivity, the entire process, from coating to exposure to developing, had to be completed before the plate dried, in a span of about 10 to 15 minutes. This modern version of...

    Explanation: The South Celestial Pole is easy to spot in star trail images of the southern sky. The extension of Earth's axis of rotation to the south, it's at the center of all the southern star trail arcs. In this starry panorama streching about 60 degrees across deep southern skies the South Celestial Pole is somewhere near the middle though, flanked by bright galaxies and southern celestial gems. Across the top of the frame are the stars and nebulae along the plane of our own Milky Way Galaxy. Gamma Crucis, a yellowish giant star heads the Southern Cross near top...

    Explanation: Familiar stars of a northern winter's night shine in this night skyview, taken near Zhangye, Gansu, China and the border with Inner Mongolia. During the early hours of December 17 Orion is near center in the single exposure that captures a fireball streaking across the sky, almost as bright as yellowish Mars shining on the right. Splitting Gemini's twin bright stars Castor and Pollux near the top of the frame, the fireball's trail and timing are consistent with the second skipping atmospheric entry of the Chang'e 5 mission's returner capsule. The returner capsule was successfully recovered after landing in...

    President Donald Trump’s legacy will go beyond his accomplishments as the 45th Commander-in-Chief who bettered the lives of Americans. The milestones he made in U.S. space exploration will no doubt last light-years after he leaves office. Here are some examples of what Trump has done to advance the U.S. presence in space: • In December, Vice President Mike Pence, at the Kennedy Space Center in Florida on Wednesday, introduced some of the 18 astronauts that the National Aeronautics and Space Administration (NASA) has chosen to be on the initial team for the early Artemis missions on and around the Moon....

    The much-discussed new strain of COVID-19 — which is reportedly more contagious than the initial strain that swept the world in 2020 — has been detected in states like California and Colorado, leaving many Americans to wonder when it might emerge in their state and how the country will fight it. Public health experts have largely agreed that the recently approved vaccines will be able to fight the mutated COVID-19 strain effectively, noting that viruses mutate constantly.

    Video of December 14, 2020 eclipse shadow at link. Explanation: What does the Earth look like during a total solar eclipse? It appears dark in the region where people see the eclipse, because that's where the shadow of the Moon falls. The shadow spot rapidly shoots across the Earth at nearly 2,000 kilometers per hour, darkening locations in its path -- typically for only a few minutes -- before moving on. The featured video shows the Earth during the total solar eclipse earlier this month. The time-lapse sequence, taken from a geostationary satellite, starts with the Earth below showing night...

    Explanation: From afar, the whole thing looks like an Eagle. A closer look at the Eagle Nebula, however, shows the bright region is actually a window into the center of a larger dark shell of dust. Through this window, a brightly-lit workshop appears where a whole open cluster of stars is being formed. In this cavity tall pillars and round globules of dark dust and cold molecular gas remain where stars are still forming. Already visible are several young bright blue stars whose light and winds are burning away and pushing back the remaining filaments and walls of gas and...

    This has been one far-out year! UFO sightings across the city are up 31% from last year — 46, compared with 35 — and an eye-popping 283% from 2018’s measly dozen, according to the National UFO Reporting Center. Brooklyn is tops in tin-foil hatters, with 12 close encounters. Not far behind are Manhattan with 11 and Queens with 10. Staten Islanders claim just eight — despite the borough’s rep for not social distancing. The Bronx is even more grounded, chalking up a mere five.

    Haim Eshed, 87, former director of space programs for the Israel Ministry of Defense for nearly 30 years said the U.S. and Israel have been in contact with alien life forms representing a “galactic federation,” and President Donald Trump knows about it. Eshed told Israel's Yediot Aharonot newspaper that “humanity is not ready,” for the public disclosure of extraterrestrials who he claims currently are in talks with government agencies on our planet. "There is an agreement between the U.S. government and the aliens. They signed a contract with us to do experiments here," he said. Parts of the interview were...

    An Estimated 1.5 billion disposable face masks will end up in the oceans this year according to a Hong Kong-based conservation organization. OceansAsia based its estimate on 52 billion masks being manufactured in 2020 to meet the demand caused by the coronavirus pandemic. Their report also says that a “conservative” calculation means at least 3 percent of them will be washed out to sea. “Single-use face masks are made from a variety of meltblown plastics and are difficult to recycle due to both composition and risk of contamination and infection,” the report says.
