We earthlings have been blessed with some pretty spectacular images from space in recent months. There was the “Blue Marble” image, the dark side of the moon, up close images of the sun, the moon and Pluto and the plumes of smoke from wildfires raging in the Western U.S. and Canada. Astronauts at the International Space Station […]
Rapper B.o.B. is the latest celebrity to take to Twitter to promote the “Flat Earth” theory, which has no support in the modern scientific community. https://twitter.com/bobatl/status/691439089543880704 His evidence includes “Why is the horizon always at eye level?,” “Why aren’t planes constantly flying into space?” and “Why can you see Philadelphia from New Jersey?” Here is a […]
Last week, two scientists announced evidence of a planet roughly the size of Neptune with a mass 10 times that of Earth‘s and a thick atmosphere of hydrogen and helium. The planet is so far away that its year would last 10,000 to 20,000 Earth-years. The planet has not actually been seen yet, though. Rather, two planetary scientists, Konstantin […]
Piers Sellers, a NASA astronaut and climate scientist, wrote an op-ed in The New York Times this past weekend after being diagnosed with Stage 4 pancreatic cancer. Poignant words of hope from friend, Piers Sellers. Life, love, and our fragile planet. https://t.co/RdDCT41otu pic.twitter.com/pm8DUBKPlf — Doug Wheelock (@Astro_Wheels) January 17, 2016 Sellers wrote: “This diagnosis puts […]
For the next few weeks, stargazers are in for a treat. It’s the first time in more than a decade that all five planets visible with the naked eye—Mercury, Venus, Mars, Jupiter and Saturn—are visible at the same time. Those in the Northern Hemisphere should look to the south about 45 minutes before sunrise, while those in the Southern […]
A rapid near-time analysis of the UK’s record-breaking wet December in 2015 suggests that climate change increased the odds of the exceptionally high rainfall by 50-75 percent. Carbon Brief takes a look at the research and quizzes of the experts on the science behind attributing extreme weather events to human-caused climate change. https://twitter.com/CarbonBrief/status/687911101149933568, suggest that […]
You’ve probably heard the rallying cry: “There is no planet B.” But maybe you are thinking Mars could make a nice new home if Earth becomes uninhabitable. If so, you should spend the next six minutes watching astronomer Lucianne Walkowicz‘s TED Talk. Walkowicz, who works on NASA’s Kepler mission, which has discovered thousands of potential […]
The phrase “ice age” may bring to mind woolly mammoths, saber-toothed cats and perhaps Sid the sloth from the animated films. It certainly doesn’t suggest ideal conditions for us distinctly-not-woolly humans. New research suggests that the impact of humans on the planet is pushing back when the Earth might descend into its next ice age. While […]
Geologists are convinced that humans have left a mark upon the planet that will be detectable millions of years from now. Long after human civilization has perished, there could be a stratum of fossilized rock and a geological time zone that says: “We were here.” So there is a case for calling the present epoch “the […]
