What Would Earth Be Like with Two Suns?
Astronomers have just discovered the first "circumbinary planet." Like Luke Skywalker's home planet of Tatooine in the "Star Wars" films, this strange world, labeled Kepler-16b, orbits two closely spaced suns. What would such a planet be like? For that matter, what if Earth had two suns instead of one? Alan Boss, an astrophysicist at the Carnegie Institution for Science in Washington, D.C., is a member of the Kepler-16b discovery team. He describes the scenery on the Tatooine-like planet, and how Earth would fare in such a binary star system. [6 Everyday Things that Happen Strangely in Space ] First off, on Kepler-16b "it's a little frosty," Boss said. "Though it is closer to its stars than Earth is to the sun, the stars aren't quite so bright, so the temperature of this planet would only be about 200 Kelvin," or nearly minus-100 Fahrenheit. Earth would be even chillier under the same stellar c…

Mysterious Radio Signals Detected From Deep Space
An initiative set up to find signs of intelligent life in the universe has detected a series of mysterious radio signals from a dwarf galaxy 3 billion light-years away. Scientists with Breakthrough Listen say they’ve found 15 fast radio bursts, or FRBs, from a deep space “repeater” called FRB 121102.  The numbers indicate when the first signal was discovered, on Nov. 2, 2012. While a few other FRBs have been detected, what makes this one unique is that it was heard again in 2015, and its location pinpointed a year later.  Breakthrough Listen used instruments at the Green Bank Telescope in West Virginia to observe that location over 5 hours on Saturday, detecting 15 bursts over the entire 4 to 8 GHz frequency band, the organization said in a news release.   “It’s very funky how the individual bursts can pop up anywhere in this wide range of frequencies, even though each individual burst has a relatively narrow frequency coverage,” Peter…

Long-dormant Yellowstone Hot Spring Erupts
t. 20.  (AP) A thermal spring near Old Faithful in Yellowstone National Park has erupted for the fourth time in the last 60 years, a park official said Thursday. Ear Spring on Yellowstone’s Geyser Hill went from being dormant on Saturday to spewing steam and water between 20 and 30 feet high, a height not recorded since 1957, said park spokesman Neal Herbert. It has since continued to erupt at a near-constant height of about 2 feet, he said. In this May 21, 2011, file photo, tourists photograph Old Faithful erupting on schedule late in the afternoon in Yellowstone National Park, Wyo.  (AP) YELLOWSTONE TOURIST TICKETED FOR WALKING TOO CLOSE, APPEARING TO URINATE ON OLD FAITHFUL Ear Spring, named for its resemblance to the shape of a human ear, is one of dozens of geysers, pools and hot springs in Yellowstone’s Upper Geyser Basin — among the park’s top attractions that feature the popular Old Faithful. It last erupted in 2004. The eruption is amo…

Powerful Super Typhoon Trami on the way to CAT 5 strength today
Super Typhoon Trami has gone through an eyewall replacement cycle lately – the pinhole eye has been replaced by a very large eye. A new intense eyewall has been established and Trami has already strengthened to 150 mph (241 km/h) sustained winds with a central pressure of around 927 Mb.
The satellite presentation was very impressive today as the final daytime light was revealing a very complex structure of the eyewall and the eye. A real monster of a typhoon, to say the least. Looking at the latest satellite animations and infrared satellite imagery, Trami is likely to reach CAT 5 strength within the next 24 hours. As mentioned in our previous discussion, very favorable ocean heat content is available along Trami’s track, so further intensification is expected.

Global Carnage awaits: Imminent solar storm to wreak havoc on power grids and electronic equipment
Last week, a weather warning was issued by experts regarding a solar storm which could hit the earth soon. Scientists believe that such an intense solar storm can wreak havoc upon power grids and electronic equipment. Tom Bogdan, an expert at the US Space Weather Prediction Centre revealed that such a gigantic solar storm could turn out to be very much devastating today when compared to the ancient days. As per experts, while modern-day humans are dependent on advanced technologies, a dangerous solar storm could disrupt their proper functioning, thus negatively impacting all the aspects of human life. Experts have classified solar storms as the biggest threat to mankind. Intense solar storms are capable of triggering blackouts and it will also disrupt the functions of satellites and air travel facilities. "Nobody's even tried to do an estimate of the worldwide cost. If there is a ma…

Movement Near San Andreas, San Jacinto Faults Explains Unusual California Earthquakes
Geoscientists who analyzed thousands of small earthquakes that occurred near the San Bernardino basin near California’s San Andreas and San Jacinto faults discovered a strange and unexpected type of movement 10 km below the Earth’s surface. Researchers think that the movement, known as “deep creep,” could be behind the unusual earthquake formations recorded in the region over the past 36 years. Jennifer Beyer and Michele Cooke, from the University of Massachusetts Amherst, developed a 3D model based on readings from thousands of small quakes in the hope that the new model can help experts better predict when and where the next major earthquake may occur. California is believed to be overdue for a particularly strong earthquake called the “Big One” which makes better earthquake prediction important. Data showed that many of the earthquakes deep below have a different style of deformation not similar to…

NASA’s planet hunter satellite gets first hit in its search for another Earth
Relocating is complicated enough when you’re simply moving to a new city. Scientists at NASA have taken property searches up an infinite number of levels, however, as they search for another Earth. NASA’s planet-hunting team turned up a potential relocation candidate on the first pass with a new satellite. The Transiting Exoplanet Survey Satellite (TESS) uses four wide-field, 16.8MP cameras designed and built by the Massachusetts Institute of Technology’s Lincoln Laboratory to capture detailed images of stars and other objects in space. The goal is to identify previously unknown exoplanets for further study. TESS recently began a two-year mission to scan the southern and northern skies. During the mission, TESS will study an unprecedented 85 percent of the sky — an expanse 350 times greater than NASA’s earlier Kepler mission. The satellite observes a sector of the sky for about 27 days before moving to the n…

NASA sent a balloon into space over North Pole - this is what they found
NASA recently sent a massive balloon with seven cameras directly over the North Pole to try and capture a glimpse of rare cloud formations and were treated with electric blue, wispy clouds formed by meteoric particles trapped in the upper atmosphere. Called noctilucent clouds, or polar mesospheric clouds (PMC), these clouds are visible only in a short interval of time in the Northern Summer just after sunset, notes a report by Fortune Magazine. Tiny ice crystals formed around space dust give off a sharp blue and white look up in the outer reaches of the atmosphere, and they are, rather stunning. Through the mission, NASA was able to shoot a staggering six million pictures using seven cameras rigged to a computer and 32 TB of onboard storage that they had on board their giant balloon, these high-resolution images offer an almost other-worldly look at this rare natural phenomenon. Called the PMC Turbo, the balloon …

How SpaceX's huge 'BFR' spaceship for Mars has changed
SpaceX's Mars-colonizing Big Falcon Rocket (BFR) spaceflight system just went through a growth spurt. The reusable rocket-spaceship duo will stand 387 feet (118 meters) tall at launch, SpaceX founder and CEO Elon Musk said Monday (Sept. 17) during a webcast event at the company's headquarters in Hawthorne, California. That's 11 percent taller than the previous design iteration, which the billionaire entrepreneur laid out in September 2017. Most of that increase comes courtesy of the BFR spaceship, whose length jumped from 157.5 feet to 180 feet (48 to 55 m). And the spaceship has changed in other important ways as well. For example, the 2017 iteration featured six Raptor engines, four of which were big-nozzled vacuum versions optimized for in-space use. But now, SpaceX envisions placing seven Raptors on the ship, all of which will be the same "sea-level" engines that power the huge BFR rocket. [Th…
