    (More comet week) Explanation: Have you ever seen a comet? Tonight -- and likely the next few nights -- should be a good chance. Go outside just at sunset and look to your northwest. The lower your horizon, the better. Binoculars may help, but if your sky is cloudless and dark, all you should need is your unaided eyes and patience. As the Sun sets, the sky will darken, and there will be an unusual faint streak pointing diagonally near the horizon. That is Comet NEOWISE. It is a 5-kilometer-wide evaporating dirty iceberg visiting from -- and returning to --...
  • Gutfeld knocks Biden over climate change plan: 'Apocalyptic nine-year vision' is 'not based on any science' (only 10.53 years left)

    "The Five" co-host Greg Gutfeld argued Tuesday that Joe Biden's strategy to combat climate change is not based on established science but rather left-wing "hysteria" conjured by Rep. Alexandria Ocasio-Cortez, D-N.Y. "Biden, economically, is kind of terrifying because he's all in on the Green New Deal, including this apocalyptic nine-year vision that is not based on any science but rather AOC-led hysteria," The "Greg Gutfeld Show" host said. During his remarks in Wilmington, Biden accused President Trump of considering climate change a "hoax," while claiming that "science tells us we have nine years before the damage is irreversible." "We are...

    Although we usually have a pretty good handle on all the different kinds of blips and blobs detected by our telescopes, it would be unwise to assume we've seen everything there is to see out there in the big, wide Universe. Case in point: a new kind of signal spotted by radio telescopes, which has astronomers scratching their heads. Four of these strange objects have been detected. All of them are circular in shape, and three are particularly bright around the edges - like a ring, or a bubble that is more opaque around the edges. An international team of...

    Over the past few years, researchers have noticed an odd clustering in the orbits of multiple trans-Neptunian objects (TNOs), which dwell in the dark depths of the far outer solar system. Some scientists have hypothesized that the TNOs' paths have been sculpted by the gravitational pull of a big object way out there, something five to 10 times more massive than Earth (though others think the TNOs may just be tugging on each other). This big "perturber," if it exists, may be a planet — the so-called "Planet Nine," or "Planet X" or "Planet Next" for those who will always...

    <p>While 2020 will be at or near record-warmth globally, this is not something we should be particularly alarmed about.</p> <p>With COVID-19 and demonstrations taking center stage in news coverage, it is easy to forget that we are all dying from climate change, anyway … or so we have been told. The recent claim at cbsnews.com that 2020 will likely be the warmest year on record (globally) leads one to ask: So what?</p>

    World Meteorological Organization (WMO) ^ | 24 June 2020 | Press Release Number: 26062020
    The new records for “megaflashes”, verified with new satellite lightning imagery technology, more than double the previous values measured in the United States of America and France. The findings were published by the American Geophysical Union’s Geophysical Research Letters ahead of International Lightning Safety Day on 28 June. WMO’s Committee on Weather and Climate Extremes, which maintains official records of global, hemispheric and regional extremes found that: The world’s greatest extent for a single lightning flash is a single flash that covered a horizontal distance of 709 ± 8 km (440.6 ± 5 mi) across parts of southern Brazil on...

    Explanation: Comet NEOWISE (C/2020 F3) is now sweeping through northern skies. Its developing tails stretch some six degrees across this telescopic field of view, recorded from Brno, Czech Republic before daybreak on July 10. Pushed out by the pressure of sunlight itself, the comet's broad, yellowish dust tail is easiest to see. But the image also captures a fainter, more bluish tail too, separate from the reflective comet dust. The fainter tail is an ion tail, formed as ions from the cometary coma are dragged outward by magnetic fields in the solar wind and fluoresce in the sunlight. In this...

    Up until now, you had to get up at about 4:00 a.m. to view Comet Neowise. Weather permitting, now starting Sunday, July 12, 2020 it can been seen on the lower northwestern horizon during/after evening twilight. Where to look? It's going to be about 5 degrees above the north/northwestern horizon starting Sunday evening at about twilight. To determine what 5 degrees are, keep reading. Hold your hand at arm’s length and close one eye, make a fist, with the back of your hand facing you. The width of your fist will approximately be 10 degrees. 5 degrees are about three...

    NBC News spent weeks documenting its science contributor’s battle with COVID-19, but now he admits that he never tested positive for it. Dr. Joseph Fair, a virologist, believed he had the virus and appeared on air numerous times to discuss his struggle with illness in May and June. On Tuesday, Fair admitted that he tested negative for the virus multiple times but had originally believed he had it regardless. Fair also tested negative upon taking an antibody test. “My undiagnosed/suspected COVID illness from nearly 2 months ago remains an undiagnosed mystery as a recent antibody test was negative,” Fair tweeted...

    The Chinese regime failed a rocket launch on July 10—the fifth unsuccessful attempt that Beijing has publicly acknowledged over four months—in its bid to further its space ambitions. The maiden launch of Kuaizhou-11, China’s largest solid carrier rocket to date with the strongest carrying capacity, failed upon its liftoff at a launch base in Inner Mongolia, causing the loss of two communication satellites it was carrying. The incident marked Beijing’s fifth rocket launch failure since March this year. Chinese authorities said they are still looking into the causes. The regime had originally planned for Kuaizhou-11’s launch as early as the...

    The amazing feat only happened once. In 1985, a F-15A Eagle fitted with a classified missile shot down an aging weather satellite. The test of the Anti-Satellite (ASAT) was considered a huge success. Task & Purpose has published a rare interview with the pilot who flew the mission 35 years ago. ============================================================================================== One of the most remarkable feats of military engineering during the Cold War was the shootdown of an actual satellite by a fighter jet. The incident was the first and only use of the AGM-135 anti-satellite (ASAT) weapon. Although anti-satellite weapon development slowed after the end of the...

    Last year, scientists detected the most energetic gamma ray burst we've ever seen. A distant galaxy spat out a colossal flare in the range of a trillion electron volts (TeV), providing invaluable new insight into the physics of these incredibly energetic events. That was pretty amazing on its own - but now astrophysicists have used the burst to perform a new, precise test of the theory of general relativity. And - quelle surprise! - this test found that the speed of light is constant in a vacuum. Relativity, once again, has passed with flying colours. The test hinges on a...

    (NASA/JPL-Caltech) ================================================================================= Life isn't always easy for astrophysicists: just when they've figured out another aspect of the patterns of movement in our Solar System, along come two of the moons of Neptune to mess everything up. The two moons in question are Naiad and Thalassa, both around 100 kilometres or 62 miles wide, which race around their planet in what NASA researchers are calling a "dance of avoidance". Their strange orbit was first detected by NASA researchers in November 2019. Compared with Thalassa, Naiad's orbit is tilted by about five degrees – it spends half of its time above Thalassa...

    Artist's conception. Image: Caltech/R. Hurt (IPAC) Astronomers from Caltech have reported that they’ve observed a collision between two black holes. Normally such an event is invisible, but this time a more massive black hole sitting nearby helped illuminate the other two as they collided. If confirmed, the findings, published in Physical Review Letters, would be the first optical observations ever made of a black hole merger. What happened: First detected in May 2019 and dubbed S190521g, the merger happened about 4 billion light-years away, within the vicinity of a supermassive black hole called J1249+3449. This object is 100 million times...
  • Scientists Have Developed a Way to Make Human Skin More Protected from Space Radiation

    NASA says that astronauts can be exposed to doses of radiation ranging from 50 to 2,000 Milli-Sieverts (mSv). Researchers already know that melanin has potential to protect astronauts from radiation. But there are different types of melanins. The one being tested on the ISS is actually a composite of fungal melanin and polymers. The lead researcher on that work is Radamés J.B. Cordero from Johns Hopkins. But this new research is going in a slightly different direction, by looking at melanin enriched with selenium. Selenium has an interesting relationship with light, and is used as a pigment, in glassmaking, in...

    Despite standing behind their data and method used to conclude there is “no evidence of anti-Black [sic] or anti-Hispanic disparities across [fatal police] shootings,” a study’s authors want to retract their work because it contradicts left-wing politics.“Although our data and statistical approach were valid to estimate the question we actually tested (the race of civilians fatally shot by police), given continued misuse of the article (e.g., MacDonald, 2020) we felt the right decision was to retract the article,” Michigan State University’s Joseph Cesario and the University of Maryland at College Park’s David Johnson wrote in their retraction request, according...

    APOD.NASA ^ | 9 Jul, 2020 | Emmanuel Paoly/NASA
    Explanation: These silvery blue waves washing over a tree-lined horizon in the eastern French Alps are noctilucent clouds. From high in planet Earth's mesosphere, they reflect sunlight in this predawn skyscape taken on July 8. This summer, the night-shining clouds are not new to the northern high-latitudes. Comet NEOWISE is though. Also known as C/2020 F3, the comet was discovered in March by the Earth-orbiting Near Earth Object Wide-field Infrared Survey Explorer (NEOWISE) satellite. It's now emerging in morning twilight only just visible to the unaided eye from a clear location above the northeastern horizon.

    NASA's Perseverance Mars rover has been attached to the top of the rocket that will send it toward the Red Planet this summer. Encased in the nose cone that will protect it during launch, the rover and the rest of the Mars 2020 spacecraft – the aeroshell, cruise stage, and descent stage – were affixed to a United Launch Alliance Atlas V booster on Tuesday, July 7, at Cape Canaveral Air Force Station in Central Florida. The process began when a 60-ton hoist on the roof of the Vertical Integration Facility at Space Launch Complex 41 lifted the nose cone,...

    All tetraquarks and pentaquarks that have been discovered so far contain two charm quarks, which are relatively heavy, and two or three light quarks – up, down or strange. This particular configuration is indeed the easiest to discover in experiments. But the latest tetraquark discovered by LHCb, which has been dubbed X(6900), is composed of four charm quarks. Produced in high-energy proton collisions at the Large Hadron Collider, the new tetraquark was observed via its decay into pairs of well-known particles called J/psi mesons, each made of a charm quark and a charm antiquark. This makes it particularly interesting as...

    There's something unusual lurking out in the depths of space: Astronomers have discovered four faint objects that at radio wavelengths are highly circular and brighter along their edges. And they're unlike any class of astronomical object ever seen before. The objects, which look like distant ring-shaped islands, have been dubbed odd radio circles, or ORCs, for their shape and overall peculiarity. Astronomers don't yet know exactly how far away these ORCs are, but they could be linked to distant galaxies. All objects were found away from the Milky Way's galactic plane and are around 1 arcminute across (for comparison, the...
