    The sun looks like a proud, happy dad with a huge smile in new photos beamed back to Earth by a sun-staring spacecraft. The new images — taken by NASA's Solar Dynamics Observatory — show various features of the sun coincidentally coming together to look just like a face with a crooked smile and male-patterned baldness. All in all, this makes the sun bear a striking resemblance to Frasier Crane or perhaps your father. The smiley sun photo was first pointed out on Twitter by solar scientist Karl Battams after the Solar Dynamics Observatory's website was updated with the new...

    Astronomers have set a new record, taking the measure of a tiny space rock just 6 feet wide. The researchers used four different telescopes on Earth to study the near-Earth asteroid (NEA), which is called 2015 TC25, during a close flyby it made of the planet in October 2015. "This is the first time we have optical, infrared and radar data on such a small asteroid, which is essentially a meteoroid," Vishnu Reddy, of the University of Arizona's Lunar and Planetary Laboratory, said in a statement. "You can think of it as a meteorite floating in space that hasn't hit...
  • TECH BLACKOUT: Huge solar storm which could WIPE OUT modern technology expected by 2020

    THERE is a one in eight chance that the Earth will be hit by a huge solar storm by 2020 which could potentially leave the world without Internet, phone service and many more services that modern-day humans rely on. Researchers have warned that there is roughly a 12 per cent chance that a solar storm could smash into Earth by the end of the decade.(emphasis mine) The powerful event would likely be as huge as the Carrington Event, which occurred on 1859. The solar storm which hit 150 years ago was so powerful that its southern auroras could be seen...

    The European Space Agency's new Mars orbiter just sent back its first high-resolution images of the Red Planet, and the view is amazing. The ExoMars Trace Gas Orbiter (TGO) arrived at Mars on Oct. 19, when its companion spacecraft Schiaparelli crash-landed on the planet's surface. Since then, TGO has been circling Mars, testing out its machinery, and taking spectacularly sharp pictures of the landscape using its Colour and Stereo Surface Imaging System (CaSSIS). ESA stitched together the best of these photos in a cool new flyover video. "The first images we received are absolutely spectacular ― and it was only...

    Researchers suggesting that the speed of light varies have come up with a numerical prediction that will allow their theory to be tested. Many theories in physics are built upon the idea that the speed of light is at a constant rate, but João Magueijo and Niayesh Afshordi think otherwise. In a paper published in the journal Physical Review D, they detailed the creation of an exact figure on the spectral index, a model that can be used to determine if their theory is valid or not. All structures in the universe today were created when fluctuations occurred in the...

    ydonia was first photographed by the Viking 1 and 2 orbiters. Between the two, eighteen images were taken of the region, all of which were of limited resolution. Of these, only five were considered suitable for studying surface features. Because of their limited quality, a particular mesa resembled a humanoid face (see below). It would be another 20 years before other spacecraft photographed the region as they conducted observations of Mars. These included NASA’s Mars Global Surveyor, which orbited Mars from 1997 to 2006; the Mars Reconnaissance Orbiter (MRO), which reached the planet in 2006 and is still in operation;...

    2. Scout the location carefully Use every tool possible to get the perfect shot, including Google Maps and compasses, to help you locate a spot where you'll be able to see the moon as well as the reference object you want to include. That may mean learning how to read a map, and finding out where the moon will appear on the horizon based on your location. If possible, travel to an area far from city lights to avoid light pollution. And make sure to be precise; Ingalls said he recalls setting up near Washington, D.C.'s Iwo Jima monument hundreds...

    Coronagraphic High Angular Resolution Imaging Spectrograph (CHARIS) has captured the light from one of those exoplanets. This has the researchers excited about what they can see. CHARIS allows astronomers to isolate light reflecting from planets. That’s difficult to do, since they are so much dimmer than the stars they orbit. CHARIS is able to isolate the reflective light from planets larger than Jupiter. Then astronomers can analyze that light to learn about the planet’s age, atmospheric composition, and its size. ... CHARIS was designed and built by a team led by N. Jeremy Kasdin, a professor of mechanical and aerospace...

    Experts suspect that President-elect Donald Trump’s space program will likely be focused on exploration with robotic probes and sending humans to Mars, using money diverted from global warming science programs. “NASA should be focused primarily on deep-space activities rather than Earth-centric work that is better handled by other agencies,” Robert S. Walker and Peter Navarro, both senior advisers to the Trump campaign, wrote in an opinion piece published in SpaceNews. “Human exploration of our entire solar system by the end of this century should be NASA’s focus and goal.” Industry analysts suspect that Trump will likely modestly increase NASA’s overall...

    Once people realized that there more than just a few asteroids out there, they took to identifying and classifying them. The book takes a loosely chronological look at this classification and at our increasing knowledge of the orbits, sizes, densities and composition of these space wanderers. Fortunately this book doesn’t just simply list discovery dates and characteristics. Rather, it includes significant amounts of its contents on the juicy human story that tags along, especially with the naming. It shows that originally these objects were considered special and refined and thus deserved naming with as much aplomb as the planets; i.e....

    Supermoon 2016. This month’s Full Moon is not only the closest for the year, but the nearest Full Moon for a 80 year plus span. Like Blue and Black Moons, a Supermoon is more of a cultural phenomenon than a true astronomical event. The Moon’s orbit is elliptical, taking it from 362,600 to 405,400 km from the Earth in the course of its 27.55 day anomalistic orbit from one perigee to the next. For the purposes of this week’s discussion, we consider a Supermoon as when the Full Moon occurs within 24 hours of perigee, and a Minimoon as when...

    HISTORY OF OUR PLANET Our Earth has been dubbed by some as the “Goldilocks Planet” with a just-right sun and a just-right moon in a just-right galaxy. What most people do not realize is how radically Earth has changed since it first formed and what kinds of physical steps transformed the lifeless ball into our home today. Earth has the capacity to support more than 7 billon people and even more billions of other creatures. Many suggest that Earth’s life sustaining features are “amazing coincidences” that just fell into place. Hugh says evidence and logic compel him to challenge such...

    Back in June 2015, a burst of galactic cosmic rays born from a giant cloud of plasma on the Sun’s corona struck Earth’s magnetic field at 2.5 million kph pounded for two hours. This produced radio signal blackouts at high altitude areas and created an unusually pronounced aurora borealis. The GRAPES-3 muon telescope, located in the Tata Institute in India, has determined those cosmic rays actually cracked the magnetosphere, warping its size and allowing additional radiation to pass through. The bombardment was able to compress the magnetosphere, from 11 to 4 times the radius of Earth. The telescope also detected...

    Millions of years ago, B3 1715+425 was just an ordinary supermassive black hole. It had a comfortable life, of devouring stars and belching deadly x-rays, at the center of its distant galaxy. Now, starless and alone, it’s screaming through space at 2,000 miles per second—and it may never stop. BC 1715+425's troubles began when its galaxy bumped up against another. This isn’t all that unusual: in fact, astronomers believe that the largest galaxies in our universe formed during ancient mergers. Normally, when two galaxies collide, the supermassive black holes at their centers start to orbit one another, moving closer and...

In fact, on June 4th of this year, the sun went completely spotless for the first time since 2011 and that quiet spell lasted for about four days. Sunspot regions then reappeared for the next few weeks on a sporadic basis, but that was followed by several more completely spotless days on the surface of the sun. The increasingly frequent blank sun is a sign that the next solar minimum is approaching and there will be an even...

That’s a little over 20% of the distance from the Earth to the Moon, and just over twice the distance to the ring of geosynchronous and geostationary satellites around the Earth. This sort of close pass of a newly discovered asteroid happens a few times a year. What made 2016 VA’s passage unusual, however, was its transit through the Earth’s shadow.

The tool is a computer program called Scout, and it's being tested at NASA Jet Propulsion Laboratory in Pasadena, Calif. Think of Scout as a celestial intruder alert system. It's constantly scanning data from telescopes to see if there are any reports of so-called Near Earth Objects. If it finds one, it makes a quick calculation of whether Earth...

    By all accounts the descent started well, with the lander decelerating rapidly as it brushed up against the Martian atmosphere, eventually deploying its parachute as planned. But things began to go squirrely just prior to the five-minute mark of the planned six-minute descent. For reasons that are still a mystery, the lander ejected both its heat shield and parachute way ahead of schedule. Schiaparelli then engaged its thrusters for a painfully brief three-second burst—a procedure that was supposed to last for 30 seconds once the lander was just a few feet off the ground. The lander’s onboard computer, it would...

    A Fourier transform analysis of 2.5 million spectra in the Sloan Digital Sky Survey was carried out to detect periodic spectral modulations. Signals having the same period were found in only 234 stars overwhelmingly in the F2 to K1 spectral range. The signals cannot be caused by instrumental or data analysis effects because they are present in only a very small fraction of stars within a narrow spectral range and because signal to noise ratio considerations predict that the signal should mostly be detected in the brightest objects, while this is not the case. We consider several possibilities, such as...

The discovery led to the widespread acceptance of the idea that our Universe is dominated by a mysterious force called dark energy, and altered the standard model of cosmology forever. But now physicists say this discovery might have been false, and they have a much larger dataset to back them up. For a bit of background on the 2011 Nobel Prize in Physics, it was shared between...

    The lander, named Schiaparelli, stopped communicating with mission control about 1 minute before its planned touchdown on Mars Wednesday morning (Oct. 19). Newly released photos of the landing site by NASA's Mars Reconnaissance Orbiter (MRO) seem to confirm what ExoMars team members had suspected — that Schiaparelli died a violent death. The photos show a bright feature consistent with the lander's 39-foot-wide (12 meters) parachute, as well as a 50-by-130-foot (15 by 40 m) dark patch likely created by the lander's impact, ESA officials said.

    In January, astronomers revealed evidence for the potential existence of another planet in the solar system. Researchers suggest that if this world — dubbed Planet Nine — exists, it could be about 10 times Earth's mass and orbit the sun at a distance about 500 times the distance from the Earth to the sun. Previous research suggested that Planet Nine would possess a highly tilted orbit compared with the relatively thin, flat zone in which the eight official planets circle the sun. This led scientists to investigate whether Planet Nine's slant might help explain other tilting seen elsewhere in the...

    NASA's Juno Jupiter probe won't be settling into its final orbit around the giant planet this week after all. Juno was scheduled to fire its main engine for the final time during the probe's close Jupiter flyby on Wednesday (Oct. 19), in a maneuver that would reduce the time it takes the spacecraft to circle the gas giant from 53 Earth days down to 14 days. But the mission team decided to postpone the burn in order to investigate an issue with valves that are part of Juno's fuel-pressurization system, NASA officials said. "Telemetry indicates that two helium check valves...

    Chinese officials unveiled plans for Monday’s launch of the country’s latest space mission in which two astronauts will be blasted into space and will dock with an orbiting space lab. The Shenzhou 11 spacecraft will be launched at 7:30 a.m., said Wu Ping, deputy director of China’s manned space engineering office, in a televised news conference. The Shenzhou mission will take off aboard a Long March-2F carrier rocket from the Jiuquan Satellite Launch Center on the edge of the Gobi Desert in northern China. …

    A new study from a team of international astronomers, led by astrophysicists from the University of Nottingham with support from the Royal Astronomical Society (RAS), has produced some astounding results: The universe contains at least two trillion galaxies, 10 times more than the highest previous estimates. What's more, the new study suggests that 90 percent of all galaxies are hidden from us, and only the remaining 10 percent can be seen at all, even with our most powerful telescopes. The paper detailing the study was published today in the Astrophysical Journal. "We are missing the vast majority of galaxies because...
  • Strange signals from 234 stars could be ET – or human error

    It’s a bold claim. Two astronomers think they have spotted messages from not just one extraterrestrial civilisation, but 234 of them. The news has sparked a lively debate in the field as other astronomers think the claim is premature and are working fast to get to the bottom of the signals. In 2012, Ermanno Borra at Laval University in Quebec suggested that an extraterrestrial civilisation might use a laser as a means of interstellar communication. If the little green men simply flashed a laser toward the Earth like a strobe light, we would see periodic bursts of light hidden in...
  • The Hidden Glaciers Of Mars

    10/14/2016 6:24:42 PM PDT · by BenLurkin · 14 replies ^ | 10/14/2016 | Matt Williams
    In the northern hemisphere of Mars, between the planet’s southern highlands and the northern lowlands, is a hilly region known as Colles Nilli. This boundary-marker is a very most prominent feature on Mars, as it is several kilometers in height and surrounded by the remains of ancient glaciers. And thanks to the Mars Express mission, it now looks like this region is also home to some buried glaciers. Such was the conclusion after the orbiting spacecraft took images that revealed a series of eroded blocks along this boundary, which scientists have deduced are chunks of ice that became buried over...
  • An Exoplanet With Huge Rings Intrigues

    10/14/2016 11:43:09 AM PDT · by BenLurkin · 12 replies ^ | 10/13/2016 | Matt Williams
    How such a ring system could have come about is a mystery, as retrograde ring systems are quite uncommon. But Reider and Kenworth have stated that they think it might be the result of a catastrophic event – such as a massive collision – that caused the rings (or the planet) to change the direction of their rotation. Their results also indicated that a retrograde ring system would allow for eclipses, like the one that was observed in 2007. While there was some chance of these being caused by another object, the results suggested otherwise. “The chance of that is...

  • Astronomers reveal how Martian moon Phobos got its distinctive shape

    Physicists from Lawrence Livermore National Laboratory (LLNL) conducted numerical 3D simulations to shed light on the mysterious circumstances surrounding Phobos’ Stickney crater. While previous studies relied on 2D simulations at lower resolutions, these were unable to replicate the feature, and failed to account for the porosity of Phobos’ crust in their calculations. According to the researchers, this moon is less dense than the Martian surface. The new calculations reveal Phobos could have survived a major impact, which left behind the massive crater. In the animation, the researchers plot a scene in which a 200-meter object slams into the moon at...
