NASA Editor's note, June 5, 2020: Asteroid 2002 NN4 will safely pass by the Earth on June 6 at a distance of approximately 3.2 million miles (5.1 milliion kilometers), about 13 times further away from the Earth than the Moon is. There is no danger the asteroid will hit the Earth. As they orbit the Sun, Near-Earth Objects occasionally approach close to Earth. CNEOS calculates the motion of all NEOs forwards to 2200 A.D. and backwards to 1900 A.D., and determines the times and distances of the Earth close approaches. more »

Can I create my own filter? Some people buy or create masks with a pocket inside to hold a filter, such as a coffee filter. When using other materials to make your own filter, such as unused vacuum cleaner bags, HEPA furnace filters, HVAC anti-allergy filters or other air filters, make sure you sandwich the filter between at least two layers of fabric to cut down on the risk of inhaling potentially harmful fibers from these materials. There are not yet conclusive data on whether or not filters provide added protection, but studies are underway. Please make sure that you can breathe easily when wearing the mask, and do not use a filter if it makes you feel short of breath. more »

A final rule limiting the science EPA can consider would significantly impact EPA’s decision-making and rulemaking process, potentially leading the agency to ignore significant scientific findings that should inform its regulatory programs. The release of a final rule rescinding emissions limits for methane on oil and gas production and processing. more »

Construction started in 1894 and the railway was opened in November 1896. Passengers were carried in a large tramcar-like carriage on a deck mounted on long stilts. It was named ‘Pioneer’ but popularly known as ‘daddy long-legs’. It was equipped with a lifeboat and lifebelts, and had to be operated by a qualified sea captain. The series includes six images of a unique electric seaside railway by Magnus Volk, the electrical engineer who designed and built Volk’s Electric Railway which opened on the seafront at Brighton in 1883 and is still in operation to this day. more »
