Officials from the U.S. Geological Survey and Hawaii’s Civil Defense Agency flew over the new lava flow at Kilauea – Hawaii’s largest volcano – on September 15 and 16, 2014 to get a close up view of the eruption. Their observations have confirmed that the lava flow from Kilauea, which began on June 27, 2014, is continuing to advance in the northeast direction across the Big Island of Hawaii and has now entered a vacant portion of the Kahoe Homesteads.
Our friend Eileen Claffey captured this fogbow over a field in Massachusetts yesterday (September 17, 2014). She said it appeared as the fog was lifting over a field. Fogbows and rainbows are made from the same configuration of sunlight and moisture. That is, you see a fogbow in the direction opposite the sun. But fogbows are caused by the small droplets inside a fog or cloud rather than the larger raindrops that cause rainbows.
Tornado records from Nebraska, Kansas, Oklahoma, and northern Texas – an area of high tornado activity dubbed Tornado Alley — show that peak tornado activity is starting and ending earlier than it did 60 years ago. That’s according to a new study published in Geophysical Research Letters on September 10, 2014.
Pluto’s moon Hydra was detected twice by the New Horizons spacecraft LORRI (LOng Range Reconnaisance Imager) camera. The detections were made on July 18, 2014 and a few days later on July 20, from a distance of 430 million kilometers / 267 million miles.
It’s been part of the conventional wisdom of modern astronomy that mergers between galaxies – which are common throughout the history of the universe – lead to the formation of massive elliptical galaxies. That idea is based on computer simulations performed in the 1970s, which have held sway ever since. Now, however, astronomers have the first evidence that merging galaxies can create disk galaxies.
An international research team has developed a new system to quantify 15 years of CO2 emissions, every hour, for the entire planet, down to the city scale.
Polar mesospheric clouds are wispy and elusive. They form 80 to 100 kilometers (50 to 60 miles) above the ground – far higher in the atmosphere than most ordinary clouds. Astronauts aboard the International Space Station (ISS), flying at 350 kilometers (220 miles) up, are ideally placed to observe them.
Today – September 17, 2014 – the sun exits the constellation Leo and enters the constellation Virgo. The sun will remain in front of the constellation Virgo the Maiden until it enters the constellation Libra the Scales on October 31. So, when the equinox arrives on September 23, the sun will be in front of the constellation Virgo. And so it has been for thousands of years. But it won’t always be that way.
A major workshop in late August 2014 represents a significant change in the debates about climbing expeditions on Mount Everest, with significance across the Himalayas and beyond. The Participatory Workshop on Roles, Responsibilities & Rights of Mountaineering Workers, held on August 29 and 30 in Kathmandu, emerged from the unsettled outcome of the tragic accident of April 18, when 16 Nepalese guides were killed at the Khumbu Icefall on Mount Everest.
