  • Hyperion is an ancient cosmic beast formed 2.3B years after Big Bang

    10/18/2018 5:59:30 PM PDT · by ameribbean expat · 41 replies
    Astronomers have discovered a massive proto-supercluster of galaxies -- bigger than even one million billion Suns. Scientists have called the ancient colossal structure Hyperion, the European Southern Observatory announced Wednesday. It is reported to have appeared just 2.3 billion years after the Big Bang, which took place about 13.7 billion years ago. The cluster's namesake is one of 12 titans born to the gods Gaia and Uranus in Greek mythology.

    NASA is considering a spectacular airship concept for Venus exploration. The space agency’s Systems Analysis and Concepts Directorate (SACD) has posted potential designs of the High Altitude Venus Operational Concept (HAVOC) on its website. The airships have even been compared to a “cloud city” by Space.com. A similar size to Earth, Venus is our closest planetary neighbor. However, exploring Venus poses a unique set of challenges, according to NASA. “Though its internal geology is similar to Earth’s, its surface is hot enough to melt lead and is covered with craters, volcanoes, mountains, and lava plains,” it explains.

    Galaxy clusters contain thousands of galaxies of all ages, shapes and sizes. Typically, they have a mass of about one million billion times the mass of the Sun and form over billions of years as smaller groups of galaxies slowly come together.The large mass of the galaxy cluster SDSS J0952+3434 creates the fascinating phenomenon of strong gravitational lensing.The cluster’s gravity bends light coming from behind it in a similar way to how the base of a wine glass bends light.The effects of this lensing can be clearly seen as an arc of light in the lower part of the new...

  • Massive glowing 'rogue' planet spotted 'drifting' in space

    A massive glowing "rogue" planetary-mass object has been discovered, surprising scientists with not only its size, but also the fact it's not orbiting a star. The object, named SIMP J01365663+0933473, has a magnetic field more than 200 times stronger than Jupiter’s and is nearly 13 times the size of the gas giant. At its size, it's right between the size of a planet and a failed star, so scientists will need to study it further to determine exactly what it is. “This object is right at the boundary between a planet and a brown dwarf, or ‘failed star,’ and is...

    A rogue, planet-size object 20 light-years away from Earth has stunned astronomers with its incredibly powerful magnetic field. The scientists found that the object's magnetic field is more than 200 times stronger than Jupiter's, which, in turn, is between 16 and 54 times stronger than Earth's, according to NASA. How the object, which scientists call SIMP J01365663+0933473, can maintain a magnetic field so strong, as well as generate spectacular auroras, is still unclear. "This particular object is exciting because studying its magnetic dynamo mechanisms can give us new insights on how the same type of mechanisms can operate in extrasolar...

    A bizarre rogue planet without a star is roaming the Milky Way just 20 light-years from the Sun. And according to a recently published study in The Astrophysical Journal, this strange, nomadic world has an incredibly powerful magnetic field that is some 4 million times stronger than Earth’s. Furthermore, it generates spectacular auroras that would put our own northern lights to shame. The new observations, made with the National Science Foundation’s Karl G. Jansky Very Large Array (VLA), not only are the first radio observations of a planetary-mass object beyond our solar system, but also mark the first time...

    Astronomers using the National Science Foundation's Karl G. Jansky Very Large Array (VLA) have made the first radio-telescope detection of a planetary-mass object beyond our Solar System. The object, about a dozen times more massive than Jupiter, is a surprisingly strong magnetic powerhouse and a "rogue," traveling through space unaccompanied by any parent star. "This object is right at the boundary between a planet and a brown dwarf, or 'failed star,' and is giving us some surprises that can potentially help us understand magnetic processes on both stars and planets," said Melodie Kao, who led this study while a graduate...

    "The new images of Occator Crater and the surrounding areas have exceeded expectations, revealing beautiful, alien landscapes," Dawn principal investigator Carol Raymond, of NASA's Jet Propulsion Laboratory (JPL) in Pasadena, California, said in a statement yesterday (July 16).  The $467 million Dawn mission launched in September 2007 with a bold goal: to orbit and study the two largest bodies in the asteroid belt: Vesta and Ceres. Both objects are considered leftovers from the solar system's planet-formation period (hence the mission's name).  Dawn reached Vesta in July 2011 and eyed the object up close for more than a year, finally leaving...

    The Kuiper Belt, the region immediately beyond Neptune, harbors TNOs of many sizes. The largest is Pluto, which was discovered more than 60 years before any of the others. Some TNOs are "detached objects," which orbit so far from the sun that they're not appreciably affected by the gravity of Neptune or any other known planet. Perhaps the most famous of these is Sedna, which takes 11,400 years to make a single orbit and never comes closer to the sun than 20 times farther out than Pluto. In 2016, astronomers Konstantin Batygin and Mike Brown announced that a distant undiscovered...

    About 11 light-years away, Ross 128 b is closer to the solar system than any known exoplanet save Proxima b. First there was Proxima b, the Earth-sized planet orbiting the closest star to us, Proxima Centauri. Then came the seven Earth-sized worlds orbiting TRAPPIST-1, a star 39 light-years away, three of which are in the habitable zone. Now we welcome a new tantalizing exoplanet to the group, the second closest we know of, also Earth-sized and temperate, orbiting a calm red dwarf star: Ross 128 b. Ross 128 is an old, inactive red dwarf star that sits 11 light-years away....

    Astronomers have found a cool, Earth-sized planet that's relatively close to our Solar System. The properties of this newly discovered planet - called Ross 128 b - make it a prime target in the search for life elsewhere in the cosmos. At just 11 light-years away, it's the second closest exoplanet of its kind to Earth. But the closest one, known as Proxima b, looks to be less hospitable for life. Found in 2016, it orbits the star Proxima Centauri, which is known to be a rather active "red dwarf" star. This means that powerful eruptions of charged particles periodically...

    The International Astronomical Union currently defines a planet as: "a celestial body that (a) is in orbit around the Sun, (b) has sufficient mass for its self-gravity to overcome rigid body forces so that it assumes a hydrostatic equilibrium (nearly round) shape, and (c) has cleared the neighborhood around its orbit." A newly suggested definition takes a different approach:

    Nerdist ^ | FEBRUARY 2, 2017 | DERRICK ROSSIGNOL
    August 24, 2006 was a dark day for Pluto enthusiasts. It was on that day that the International Astronomical Union established three conditions a celestial body must meet in order to be considered a planet. A planet must orbit around the sun, it must be massive enough to be rounded by its own gravity, and it must have “cleared the neighborhood” around its orbit, which means, simply put, that it must have a certain amount of gravitational pull. Pluto does not meet the third condition, so once those rules were put in place, Pluto was demoted to “dwarf planet,” 75...

    “Of the seven million Gaia stars with full 3D velocity measurements, we found twenty that could be traveling fast enough to eventually escape from the Milky Way,” said team member Dr. Elena Maria Rossi, an astronomer at Leiden Observatory.“Rather than flying away from the Galactic center, most of the high velocity stars we spotted seem to be racing towards it,” added team leader Dr. Tommaso Marchetti, also from Leiden Observatory.“These could be stars from another galaxy, zooming right through the Milky Way.”It is possible that these intergalactic interlopers come from the Large Magellanic Cloud, a relatively small galaxy orbiting the...

    On Earth, the sublimation of massive ice deposits at equatorial latitudes under cold and dry conditions in the absence of any liquid melt leads to the formation of spiked and bladed textures eroded into the surface of the ice.Known as penitentes, these sublimation-sculpted blades grow to between 3 to 16 feet (1-5 m) tall, but they are restricted to high-altitude tropical and subtropical conditions, such as in the Andes.Europa, however, has the perfect conditions necessary for penitentes to form more uniformly — its surface is dominated by ice.It has the thermal conditions needed for ice to sublime without melting; and...
  • Jupiter's Moon Ganymede Generates Incredible Magnetic Waves

    NASA’s Galileo spacecraft surprised scientists when it revealed that Jupiter’s moon Ganymede generated its own magnetic field. But new research shows Ganymede also creates incredibly powerful waves that rocket particles to enormous energies. Scientists revealed these huge electromagnetic waves while studying old data from Galileo, which orbited Jupiter from 1995 to 2003. The observations show another wild way that a moon can interact with the magnetic field of its planet. Jupiter’s radius is around 11 times that of Earth, but it is perhaps 20,000 times more magnetic. This generates an intense radiation environment around the planet. Typically, these waves around...

    Our Moon's appearance changes nightly. As the Moon orbits the Earth, the half illuminated by the Sun first becomes increasingly visible, then decreasingly visible. The featured video animates images taken by NASA's Moon-orbiting Lunar Reconnaissance Orbiter to show all 12 lunations that appear this year, 2018. A single lunation describes one full cycle of our Moon, including all of its phases. A full lunation takes about 29.5 days, just under a month (moon-th). As each lunation progresses, sunlight reflects from the Moon at different angles, and so illuminates different features differently. During all of this, of course, the Moon always...
