Nevada skies were brightened up by a streak of light on December 22 2015, reported Fleischmann Planetarium Director, Dan Ruby. The light was seen by people in and around Las Vegas as well as Bakersfield and Sacramento in California. The Los Angeles Astronomical Society revealed that the December 22 overnight was the peak of the Ursids meteor shower. It was also reported that the celestial object that caused light appeared to disintegrate in the sky.
The California Department of Fish and Wildlife on Tuesday confirmed the presence of domoic acid in the California’s Dungeness crab. The department also mentioned that people should strictly avoid consumption of the crab this Christmas.
Officials said that the level of acid found in crabs is worrisome and are far beyond the standards set by the California Department of Public Health for safe consumption.
California Department of Fish and Wildlife spokeswoman Jordan Traverso said in a statement that they have even found some crab samples coming without the presence of acid.
Astronomers have lately warned that earth is at increased risk of space rock impact than estimated risk. In their warning, astronomers have pin-pointed towards giant comets known as centaurs having much larger orbits.
In the last two decades, astronomers said that hundreds of centaurs have been discovered. These balls of ice and dust pose great risk to earth. Centaurs are around 50 to 100 kilometers wide and their features include- highly unstable, elliptical orbits starting way beyond Neptune, which is the most distant planet from the sun.
NASA’s Lunar Reconnaissance Orbiter (LRO) has beamed back a breathtaking ‘Earthrise’ image. The gorgeous new picture taken from space reminds of two most famous pictures of our home planet taken years ago.
The US space agency released the stunning image on Friday where earth’s center is off coast of Liberia. Other visible parts in the image are the Sahara Desert, Saudi Arabia and Atlantic and Pacific coasts of South America.
Significant decline has come in population of wild bees in some of the main agricultural regions of America, unveiled the first national map of bee populations. The researchers have pinpointed 139 counties that are especially at greater risk.
The researchers noticed a trend that wild bees, important pollinator for many crops, are declining and farmland for crops heavily dependent on these pollinators is on rise. The counties at high risk include Northwest, the upper Midwest and Great Plains, west Texas and the southern Mississippi River valley.
Amazon Web Services (AWS), Infosys and YC Research are giving a donation of US$1 billion to fund the OpenAI project. The companies are funding the project without any expectations of making financial profits. The project is aimed at providing benefits of Artificial Intelligence (AI) to the entire humanity.
In a latest discovery, a woolly mammoth tusk has been found at a gravel pit east of Saskatoon. It is believed to be between 12,000 and 15,000 years old. The Royal Saskatchewan Museum’s Tim Tokaryk said that the fossil was discovered by Inland Aggregates at their work site in previous fall.
Tokaryk said that researchers would get some help from the tusk in expanding their knowledge of where woolly mammoths once used to roam. He also said that such discoveries at in work areas are quite rare.
Not being spotted for more than 15 years led researchers believe that a rare species of sea snakes has gone extinct. To their surprise, a pair of Western Australian sea snake species was spotted off the coast of Western Australia.
Scientists from James Cook University said that they have been spotted for the first time and that too alive and in good health after more than 15 years. They mysteriously disappeared from their only known habitat on Ashmore Reef in the Timor that led researchers think the snake has been disappeared completely.
Spotted for the first time by NASA's Saturn-orbiting Cassini spacecraft in 2005, a new picture shows the varied terrain of Saturn's icy, ocean-harboring moon Enceladus. Captured from a distance of 85,000 miles (137,000 kilometers), the picture shows that some portions of Enceladus' surface are much younger than others.
Describing the image that was released on December 21, officials from the US space agency NASA said the newer surfaces (as seen on the left in the image) would not have had time to accumulate craters.
Arctic permafrost’s ability to emit carbon dioxide and methane in large quantity, which could have been underestimated so far, has made it a hot topic for discussion among scientists, activists and policymakers and all others debating climate change. Methane is in focus because it is potent though relatively short-lived greenhouse gas.
