    The Turkish Science Minister has become the latest public figure to make outrageous claims over Islam's hand in science and technology, the Hurriyet Daily News reported Friday - this time, claiming that Muslims discovered that the world is round. "Some 700-800 years before Galileo, 71 Muslim scientists led by al-Khwarizmi convened by the order of the Caliph Al-Ma'mun and revealed that the Earth is a sphere," Minister Fikri stated on Thursday. Fikri further claimed that a copy of the original document proving Islam's role in astronomy is currently in the Museum of Islamic Science and Technology in Istanbul. The Earth...

    Gravitational waves are caused by calamitous events in the Universe. Neutron stars that finally merge after circling each other for a long time can create them, and so can two black holes that collide with each other. But sometimes there's a burst of gravitational waves that doesn't have a clear cause. One such burst was detected by LIGO/VIRGO on January 14, and it came from the same region of sky that hosts the star Betelgeuse. Yeah, Betelgeuse, aka Alpha Orionis. The star that has been exhibiting some dimming behaviour recently, and is expected to go supernova at some point in...

    Meteor Explosion Near Puerto Rico Captured by a Satellite Meteorologist Danielle Banks says a NOAA satellite captured what appears to be a meteor exploding near Puerto Rico. At a Glance The bright ball of fire was captured in satellite images. Residents posted photos and video to social media. One astronomer guessed it was several feet in length. A bright ball of fire shot across the sky in Puerto Rico Friday afternoon, prompting local residents to speculate on what it was, and to wonder if it was a bad omen for the disaster-stricken island. Images of the fireball were captured by...

    Brad Pitt is making a movie about him Space is a fiction invented by white people, who should be removed from earth. Black people should be removed from the earth – to prevent white people from colonizing other worlds. Is this simply a freewheeling debate led by an eccentric two-time national champion-turned-instructor, or a fireable offense? A student at Weber State University is demanding the firing of Ryan Wash, whose life story will be told in a Brad Pitt-financed biopic, calling him a “racist professor” who was teaching an “anti-white curriculum” to his students. Freshman Michael Moreno secretly recorded Wash...

    SpaceX has launched 60 more mini internet satellites, this time testing a dark coating to appease stargazers. It is a “first step” compromise between SpaceX and astronomers fearful of having dark skies spoiled by hundreds and, eventually, thousands of bright satellites circling overhead. The Falcon 9 rocket blasted into a cold, clear night sky, recycled by SpaceX for its fourth flight. As the first-stage booster flew to a vertical landing on an ocean platform, the Starlink satellites continued hurtling towards orbit to join 120 similar spacecraft launched last year. Flight controllers applauded and the launch commentator described the booster’s fourth...
  • An 'unknown' burst of gravitational waves just lit up Earth's detectors

    Earth's gravitational wave observatories -- which hunt for ripples in the fabric of space-time -- just picked up something weird. The Laser Interferometer Gravitational-Wave Observatory (LIGO) and Virgo detectors recorded an unknown or unanticipated "burst" of gravitational waves on Jan. 14. The gravitational waves we've detected so far usually relate to extreme cosmic events, like two black holes colliding or neutron stars finally merging after being caught in a death spiral. Burst gravitational waves have not been detected before and scientists hypothesize they may be linked to phenomena such as supernova or gamma ray bursts, producing a tiny "pop" when...

    The oldest solid material on Earth has just been identified, and it predates the Solar System itself by at least a few hundred million years. The teensy tiny microscopic grains of dust were forged in a distant star somewhere between 5 and 7 billion years ago, according to new research. By comparison, our Sun is just 4.6 billion years old. Eventually, these grains were carried to Earth in a meteorite. "This is one of the most exciting studies I've worked on," said cosmochemist Philipp Heck of the Field Museum of Natural History and the University of Chicago. "These are the...

    1. The Earthiest Kepler-78b is most similar to Earth in mass, diameter and composition; it could be made of rock with an iron core. But it’s no Earth analog, whizzing around its star in 8.5 hours, with temperatures exceeding 2,000° Celsius (SN Online: 10/30/13). 2. The wettest HR 8799c’s atmosphere lacks methane, which could signal life, but does have water and carbon monoxide (SN: 4/6/13, p. 5). Water has also been found in the atmospheres of WASP-17b, HD209458b, WASP-12b, WASP-19b and XO-1b. 3. The rogue Planetary candidate PSO J318.5-22 has no parent star. The object is roughly six times the...

    Astronomers have discovered that a huge, searing-hot planet orbiting another star is loaded with an unusual amount of carbon. The planet, a gas giant named WASP-12b, is the first carbon-rich world ever observed. The discovery was made using NASA's Spitzer Space Telescope, along with previously published ground-based observations. "This planet reveals the astounding diversity of worlds out there," said Nikku Madhusudhan of the Massachusetts Institute of Technology, Cambridge, lead author of a report in the Dec. 9 issue of the journal Nature. "Carbon-rich planets would be exotic in every way -- formation, interiors and atmospheres." It's possible that WASP-12b might...

    The popular Jupiter Shield theory proposes that the planet acts like a giant space shield due to its huge mass causing it to suck in or deflect dangerous debris. However, this shield theory is slowly falling out of favor and one of the leading critics is space expert Kevin Grazier. [Kevin R. Grazier, Ph.D.] He's published several papers explaining why he thinks Jupiter is a "sniper rather than a shield". Recently, he's been aiming to prove how this 'sniper-like' process works. Grazier's extensive work could put the Jupiter Shield theory in jeopardy. He told Gizmodo: "Actually, I wouldn't say that...

    TOI 700 d is a landmark discovery for NASA’s Transiting Exoplanet Survey Satellite NASA’s newest planet hunter just bagged some big game. For the first time, the agency’s Transiting Exoplanet Survey Satellite (TESS) has discovered a roughly Earth-size planet in the habitable zone of its host star, the zone of orbital distances where liquid water could be stable on a world’s surface, researchers announced today (Jan. 6). The newfound exoplanet, known as TOI 700 d, lies just 101.5 light-years from Earth, making it a good candidate for follow-up observations by other instruments, scientists added. “TESS was designed and launched specifically...

    The cycle may result in dramatic space weather that could disrupt communications and power grids here on Earth. Two new sunspots have ended a long period of relative quiet on the surface of our blazing host star, heralding the start of a new 11-year cycle of sunspot activity — resulting in sometimes dramatic space weather that could disrupt communications and power grids here on Earth. The two new sunspots, designated as NOAA 2753 and 2754, were seen on Dec. 24 by NASA's Solar Dynamics Observatory — a satellite that monitors the exterior and interior of the sun from a geosynchronous...
  • A Huge Wave is Passing Through the Milky Way Unleashing New Stellar Nurseries

    Stars are formed within large clouds of gas and dust known as stellar nurseries. While star formation was once seen as a simple gravitational process, we now know it is a complex dance of interactions. When one star forms it can send shock waves through the interstellar medium that trigger other stars to form. Supernovae and galactic collisions can trigger the creation of stars as well. In the late 1800s, astronomer Benjamin Gould studied OB stars and found that many of them lie within a partial ring within our galaxy, titled about 20 degrees from the plane of the Milky...

    Our magnificent gravitational wave astronomers have done it again, adding to the detection collection a new collision between two neutron stars. On 25 April 2019, the LIGO interferometer detected two neutron stars around 520 million light-years away coming together and merging into a single object. It's called GW190425, and although it's only the second such collision astronomers have ever seen, it's already broadening our understanding of these colossal cosmic smash-ups.

    [R]esearchers using NASA's TESS (Transiting Exoplanet Survey Satellite) and the Spitzer Space Telescope have confirmed the presence of a nearby planet called TOI 700 d. The world sits comfortably in the habitable zone of its host star, and from what astronomers can tell, it appears to be a lot like Earth. The best part? It's relatively close. Okay, so as we've all come to learn, "close" is a relative term when we're talking about objects in space. In the case of TOI 700 d, "close" means that the planet is hanging out at a distance of around 100 light-years. That's...

    Currently, the faint star V Sagittae, V Sge, in the constellation Sagitta, is barely visible, even in mid-sized telescopes. However, around the year 2083, this innocent star will explode, becoming as bright as Sirius, the brightest star visible in the night sky. During this time of eruption, V Sge will be the most luminous star in the Milky Way galaxy. This prediction is being presented for the first time at the 235th American Astronomical Society meeting in Honolulu, HI, by astronomers Bradley E. Schaefer, Juhan Frank, and Manos Chatzopoulos, with the Louisiana State University Department of Physics & Astronomy. V...

    A mysterious repeating radio signal from space revealed last year is now the fifth fast radio burst to be tracked back to its source galaxy. It's a location unlike any of the others, and astronomers are having to rethink their previous assumptions about how these signals are generated. The origin of this repeating signal is a spiral galaxy, located 500 million light-years from Earth, making it the closest known source of what we call fast radio bursts (FRBs) yet. And the FRBs are emanating specifically from a region just seven light-years across - a region that's alive with star formation....
