KIC 12557548 History of detection[edit] The existence of the planet was first evidenced in data collected by the Kepler spacecraft. However, the light curve of the star, a graph of its stellar flux versus time, showed that while there were regular drops in stellar flux approximately every 15 hours, the amount of light being blocked covered a wide range, from 0.2% to 1.3% of the starlight being blocked.[2] Rappaport et al. (2012) proposed various possible phenomena which may have caused the anomalies in the light curve, including two planets orbiting each other,[6] and an eclipsing binary orbiting the star in a larger triple-star system.[2] However, the authors found the hypothetical binary planet system to be unstable[2] and the latter scenario to be poorly supported by the data collected by Kepler.[2] Planetary system[edit] References[edit] ^ Jump up to: a b c d e f "Basic data: 2MASS J19235189+5130170 -- Infra-Red source".

Future - Are we on the road to civilisation collapse? Great civilisations are not murdered. Instead, they take their own lives. This article is part of a new BBC Future series about the long view of humanity, which aims to stand back from the daily news cycle and widen the lens of our current place in time. Modern society is suffering from “temporal exhaustion”, the sociologist Elise Boulding once said. “If one is mentally out of breath all the time from dealing with the present, there is no energy left for imagining the future,” she wrote. That’s why the Deep Civilisation season will explore what really matters in the broader arc of human history and what it means for us and our descendants. So concluded the historian Arnold Toynbee in his 12-volume magnum opus A Study of History. He was right in some respects: civilisations are often responsible for their own decline. The Roman Empire, for example, was the victim of many ills including overexpansion, climatic change, environmental degradation and poor leadership. You might also like:
This Is What Dog Breeds Looked Like A 100 Years Ago Due to our strange beauty ideals, even dogs had to suffer a lot. Many dog breeds used to look very different 100 years ago from what they look like now. 1. Now: Then: Today’s Bull Terrier has been seriously impaired by breeding. 2. As the picture makes quite obvious, today’s German Shepherd, with their stunted hind quarters, experience frequent and painful leg problems. 3. The pug, while being in very high demand, has been notoriously genetically modified, and has suffered badly for our meddling. 4. Among dogs, the Boxer breed of today has one of the highest cancer rates. 5. The Salukis of today have had their skeletal appearance enhanced, and it introduced a higher rate of heart problems. 6. Looking at this photo provides a perfect perspective as to the cruelty of aestheticism. 7. The White Terrier was once a highly functional, athletic dog. 8. It’s quite obvious that the Bearded Collie has been seriously toyed with genetically. 9. The Saint Bernard cannot function anymore. 10. 11.
History of the Earth The history of the Earth concerns the development of the planet Earth from its formation to the present day.[1][2] Nearly all branches of natural science have contributed to the understanding of the main events of the Earth's past. The age of Earth is approximately one-third of the age of the universe. An immense amount of biological and geological change has occurred in that time span. The first life forms appeared between 3.8 and 3.5 billion years ago. Geological change has been constantly occurring on our planet since the time of its formation and biological change since the first appearance of life. Geological time, condensed in a diagram displaying the relative lengths of the eons of Earth's history Geologic time scale[edit] The history of the Earth is organized chronologically in a table known as the geologic time scale, which is split into intervals based on stratigraphic analysis.[2][6] A full-time scale can be found at the main article.

How to Think Like a Futurist: DevLearn 2017 Closing Keynote DevLearn 2017 wrapped up with a thought-provoking closing keynote, “How to Think Like a Futurist,” by Jane McGonigal, PhD, director of games research and development at the Institute for the Future. She helped us level up our powers of creativity and imagination for thinking about the future. First-person thinking McGonigal compared two ways to imagine the future: using impersonal facts or thinking in the first person. One example of possible future facts: “In the future, there will be a climate change. By 2050, sea levels may rise by as much as 9 feet and 750 million people may be displaced.” First-person thinking connects you to your future self because the brain fires up faster, with more flexibility, making more connections (Figure 1). Don’t be a stranger to your future self Something else to keep in mind is that when we try to imagine ourselves far into the future, we are likely to see a stranger.

Why do dogs bleed during estrus Archives - Why Do Dogs? You likely already know that intact (unspayed) female dogs bleed but may be wondering why do dogs get a period? In reality, dogs do not get a period like women do as their reproductive system works different. By understanding how a dog’s heat cycle works, you can understand why it is wrong to say that “dogs get a period.” Dogs Get Heat Cycles Dogs do not get menstrual cycles with a period every month like women do, they get heat cycles instead. Dogs generally tend to go into heat every 6 to 12 months (depending on breed) and their heat cycle lasts for about three weeks. When dogs bleed, it’s sign that they are in the proestrus stage of the cycle, a stage that lasts for about a week. Afterward, the blood turns straw colored for another week. The third week is when female dogs are finally going out of season and the discharge will stop. This final stage is known as diestrus, and if the dog was not impregnated during the estrus stage, the body returns to a state of normalcy. References:
Future of the Earth Conjectured illustration of the scorched Earth after the Sun has entered the red giant phase, 7 billion years from now.[1] During the next four billion years, the luminosity of the Sun will steadily increase, resulting in a rise in the solar radiation reaching the Earth. This will cause a higher rate of weathering of silicate minerals, which will cause a decrease in the level of carbon dioxide in the atmosphere. In about 600 million years, the level of CO 2 will fall below the level needed to sustain C3 carbon fixation photosynthesis used by trees. In about 1.1 billion years, the solar luminosity will be 10% higher than at present. Human influence[edit] There are multiple scenarios for known risks that can have a global impact on the planet. Should the human race become extinct, then the various features assembled by humanity will begin to decay. Random events[edit] A supernova is a cataclysmic explosion of a star.

the shock of the anthropocene In 2003 the Australian philosopher Glenn Albrecht coined the term solastalgia to mean a “form of psychic or existential distress caused by environmental change”. Albrecht was studying the effects of long-term drought and large-scale mining activity on communities in New South Wales, when he realised that no word existed to describe the unhappiness of people whose landscapes were being transformed about them by forces beyond their control. He proposed his new term to describe this distinctive kind of homesickness. Where the pain of nostalgia arises from moving away, the pain of solastalgia arises from staying put. Where the pain of nostalgia can be mitigated by return, the pain of solastalgia tends to be irreversible. Solastalgia is not a malady specific to the present – we might think of John Clare as a solastalgic poet, witnessing his native Northamptonshire countryside disrupted by enclosure in the 1810s – but it has flourished recently. The group’s report is due within months.
John Wayne Gacy American serial killer (1942–1994) Gacy was convicted of the sodomy of a teenage boy in Waterloo, Iowa, in 1968 and was sentenced to 10 years' imprisonment, but served 18 months. He murdered his first victim in 1972, had murdered twice more by the end of 1975, and at least 30 subsequent victims were killed after his divorce from his second wife in 1976. The investigation into the disappearance of Des Plaines teenager Robert Piest led to Gacy's arrest on December 21, 1978. His conviction for 33 murders was the most by one individual in United States history at the time. Early life John Wayne Gacy was born in Chicago on March 17, 1942, the second child and only son of John Stanley Gacy (June 20, 1900 – December 25, 1969) and Marion Elaine Robison (May 4, 1908 – December 6, 1989).[3] His father was an auto repair machinist and World War I veteran, and his mother was a homemaker. Childhood Career origins The same year Gacy's political involvement began, his father bought him a car. Las Vegas
Holocene extinction The dodo, a flightless bird of Mauritius, became extinct during the mid-late seventeenth century after humans destroyed the forests where the birds made their homes and introduced mammals that ate their eggs. The Holocene extinction includes the disappearance of large mammals known as megafauna, starting between 9,000 and 13,000 years ago, the end of the last Ice Age. This may have been due to the extinction of the mammoth that had maintained grasslands that became birch forests without the mammoths.[3] The new forest and the resulting forest fires may have induced climate change.[3] Such disappearances might be the result of the proliferation of modern humans which led to climate change. These extinctions, occurring near the Pleistocene–Holocene boundary, are sometimes referred to as the Quaternary extinction event. The Holocene extinction continues into the 21st century.
