    You knew it had to happen sooner or later. After all, if a biological, chromosomal male who identifies as female can have his birth certificate changed to female, why can’t a 69-year-old man who feels like he’s 49 have his age legally changed?Why is one biological reality – namely, sex – changeable, while another biological reality – namely, age – not changeable? And haven’t we heard for years that age is just a number? Why not change the number, especially when numbers do matter when it comes to age?After all, there is the age when you can drive or drink or...

    Three chunky asteroids will zoom by Earth this weekend, and one of them is getting closer to our planet than the moon itself. On Saturday (Nov. 10), the near-Earth asteroid 2018 VX1 will zip within about 236,100 miles (380,000 kilometers) of Earth. That's closer than the moon, which hangs out about 238,900 miles (384,400 km) away as it orbits Earth. Gianluca Masi, founder and director of the Virtual Telescope Project in Italy, which is live-streaming the celestial show online here starting at 1 p.m. EST (18:00 UTC) on Saturday. … People here on Earth will be able to see the...

    ESO 338-4, also known as LEDA 63240 and IRAS 19245-4140, is classified as a blue compact dwarf galaxy. It resides in the constellation Corona Australis, some 100 million light-years from Earth.Blue compact dwarf galaxies take their name from the intensely blue star-forming regions that are often found within their cores.One such region can be seen embedded in ESO 338-4, which is populated with bright young stars voraciously consuming hydrogen.These massive stars are doomed to a short existence, as despite their vast supplies of hydrogen fuel.The nuclear reactions in the cores of these stars will burn through these supplies in only...

    The Universe’s first stars after the Big Bang would have consisted entirely of elements like hydrogen, helium, and small amounts of lithium.Those stars then produced elements heavier than helium in their cores and seeded the Universe with them when they exploded as supernovae.The next generation of stars formed from clouds of material laced with those metals, incorporating them into their makeup.The metal content, or metallicity, of stars in the Universe increased as the cycle of star birth and death continued.2MASS J18082002-5104378 B, also known as Gaia DR2 6702907209758894848 B, is unusual because unlike other stars with very low metal content,...

    SpaceX founder and CEO Elon Musk is a big "Hitchhiker's Guide" fan, as Starman's Roadster shows. The car's entertainment display was programmed to read "Don't Panic!" — the phrase that adorns the cover of the eponymous electronic guidebook in Adams' beloved series. Musk has said that he launched the Roadster and Starman because the duo is a lot more fun than the typical inert-mass dummy payload... Launching a satellite or other valuable spacecraft wasn't an option, given the risks inherent in maiden flights. The Roadster and Starman will come within a few hundred thousand kilometers of our planet in 2091,...

    NASA may have ruled that Oumuamua, the first interstellar object ever spotted in our system is a "metallic or rocky object" approximately 400 meters (1,312 feet) in length and 40 meters (131 feet) wide, but a new study from the Harvard Smithsonian Center for Astrophysics says it could be something much more exciting – it could be "a lightsail of artificial origin" sent from another civilization. The study, which was posted online earlier this month, suggests that Oumuamua's strange "excess acceleration" could be artificial in nature, as it has been implied that it is not an active comet.

    This story came out earlier this week but it was shocking enough that it bears a look. The transgender activist community was all abuzz on Thursday over a letter that had actually been featured in the New York Times a week earlier. Buzzfeed picked it up and ran with it, adding to the celebratory mood. The document in question was an open letter published by a gaggle of 1,600 scientists who are rejecting the anticipated HHS memo defining sex and gender in traditional, scientifically accepted terms for purposes of Title IX questions. What’s truly amazing is the fact that these...

    Astronomers using the GRAVITY instrument on ESO’s Very Large Telescope Interferometer (VLTI) have detected flares of infrared radiation coming from the accretion disk around Sagittarius A*, the 4-million-solar-mass black hole at the heart of our Milky Way Galaxy. The flares the GRAVITY instrument detected provide long-awaited confirmation that the object in the center of our Galaxy is a supermassive black hole.The flares originate from material orbiting very close to the black hole’s event horizon — making these the most detailed observations yet of material orbiting this close to a black hole.While some matter in the accretion disk — the belt...

    Three unusual happenings have sparked claims that Biblical prophecies about the end of the world and the coming of the Messiah may be coming true. The first occurrence was the birth of the first 'red heifer in 2,000 years' in Israel - a creature that features in 'end of times' tales in both Christianity and Judaism. The news of the birth, which emerged in September, was followed by claims last month that fish and other forms of life are quickly filling up Dead Sea sinkholes. Hebrew prophet Ezekiel’s end-of-days prophecy foresees the sea - a hypersaline environment, with a reported...

    Brightly colored molecular models line two walls of Yet-Ming Chiang’s office at MIT. Chiang, a materials science professor and serial battery entrepreneur, has spent much of his career studying how slightly different arrangements of those sticks and spheres add up to radically different outcomes in energy storage. But he and his colleague, Venkat Viswanathan, are taking a different approach to reach their next goal, altering not the composition of the batteries but the alignment of the compounds within them. By applying magnetic forces to straighten the tortuous path that lithium ions navigate through the electrodes, the scientists believe, they could...

    Rather than sucking space ships into a space-station, a tractor beam created by University of Adelaide researcher Ashby Hilton and his colleagues pulls atoms into a microscopic hole at the center of a special optical fiber. “Although tractor beams are green or blue in the movies, in this case the trap is made of invisible infrared light,” Hilton said. “The beam grabs hold of atoms that are floating in a chamber that is almost completely emptied of gas — a little sample of outer space on Earth.” “Every atom that enters the tractor beam is pulled into the fiber —...

    What Is the “Dark Energy” That Scientists Seek to Measure and Define? Msgr. Charles Pope • October 31, 2018 • In 1929, Edwin Hubble discovered that the universe was not static but was in fact expanding outward from some point of singularity. At first his fellow scientists ridiculed his theory, labeling it with the term “the big bang.” Even as late as the 1960s I remember being taught in school that the universe was eternal and fixed. That “settled science” has since given way to the current view that the universe is expanding outward—quite rapidly, in fact.There is more,...

    You may not have heard of The Melancholy of Haruhi Suzumiya, but, among anime fans at least, it’s a pretty big deal. Originally a series of light novels, it follows the adventures of typical high schooler Kyon and the time-travel alien ESP club he is forced to help create by his beautiful if eccentric friend, the titular Haruhi. Since its original run in 2003, it has spawned 10 additional volumes, a film adaptation, several video games, and even its own religion, Haruhiism. It was first adapted into an anime back in 2006. The show only lasted three months but there...

    “This is the first time that such a large structure has been identified at such a high redshift, just over 2 billion years after the Big Bang [~13.7 billion],” said lead author Dr. Olga Cucciati, an astronomer at the Istituto Nazionale di Astrofisica, Italy.“Normally these kinds of structures are known at lower redshifts, which means when the Universe has had much more time to evolve and construct such huge things. It was a surprise to see something this evolved when the Universe was relatively young!”Located in the COSMOS field in the constellation of Sextans, Hyperion was identified by analyzing the...

    Let's talk about dark energy. We've known for about 20 years that the expansion of our universe is accelerating; every day, our cosmos grows bigger and bigger, doing so faster and faster. It's a subtle effect, and it takes extensive and deep cosmological surveys and studies for scientists to notice it. But multiple independent lines of evidence all point to the same conclusion: accelerating expansion. Astronomers quickly cooked up a cool name for that accelerated expansion: dark energy. But now we’re left with the much harder job of finding a culprit — what's causing it? A universal mistake We use...
  • HUBBLE JUST SPOTTED SOMETHING MASSIVE COMING OUT OF URANUS

    Bursts of solar winds caused a huge sparkling region on Uranus, scientists observed this by using Hubble space telescope. Electrons that come from various origins such as solar winds, the planetary ionosphere and moon volcanism, when charged in the form of streams caused this, researchers from the Paris Observatory used the NASA/ESA Hubble Space Telescope to observe this on Uranus. They were able to catch it in powerful magnetic fields and, controlled it into the upper atmosphere, where set off spectacular bursts of light when made interactions with gas particles, such as oxygen or nitrogen.

    If you’ve ever wanted to get a really good look at Uranus, then tonight is your best opportunity. Not only is the distant planet at the closest point to Earth in its orbit at the moment, but it’s also particularly easy to locate. The seventh planet from the sun can be found just to the left of the moon in the night sky all this week. The moon is starting to wane after last night’s full moon, but it will still be shining brightly in the sky. Helpful for locating the distant planet. Uranus lies south-west in the constellation of...

    Blue asteroids are rare, and blue comets are almost unheard of. An international team led by Teddy Kareta, a graduate student at the University of Arizona's Lunar and Planetary Laboratory, investigated (3200) Phaethon, a bizarre asteroid that sometimes behaves like a comet, and found it even more enigmatic than previously thought. Phaethon sets itself apart for two reasons: it appears to be one of the "bluest" of similarly colored asteroids or comets in the solar system; and its orbit takes it so close to the Sun that its surface heats up to about 800 degrees Celsius (1,500 degrees Fahrenheit), hot...
