What is hail or a hailstone? Hail is a form of precipitation that occurs when updrafts in thunderstorms carry raindrops upward into extremely cold areas of the atmosphere where they freeze into balls of ice. Hail can damage aircraft, homes and cars, and can be deadly to livestock and people. How does hail form? Hailstones grow by colliding with supercooled […]

For the first time, scientists have caught a glimpse of a black hole ejecting a hot “flare” of matter after devouring a star the size of our sun. The discovery was made thanks to the quick action of of scientists from John Hopkins University, who worked in conjunction with a team from the University of Oxford. Hubble fellow Sjoert van […]

The world’s leading economies are heading in the right direction on tackling climate change, but some still have a long way to go to make their undertakings politically credible, according to a UK research center. With the Paris Agreement barely two months old, the world now moves from talk to action − or at least that’s the theory. The Agreement […]

Due to high temperatures recently the UN (United Nations) has declared that the high temperatures will influence extreme weather conditions now and in the near future. The World Meteorological Organization has reported that 2016 was the hottest year on record and getting a lot warmer. With the devastating bush fires in Australia 2020 is turning out to be a very […]

Climatologists have started to drill into the oldest ice core in Antarctica to find some air that may have been there around 1 million to 900,000 years ago. The teams are from Australia, China, and Europe in a friendly type competition to find samples of air that is about 1.5 million years old. They would like to find out what […]

The Seabin marine waste collector shows how often the simplest solutions are the most effective. The rubbish collector, designed to float in marinas, inland waterways, residential lakes and harbors, collects floating debris and liquids by sucking water from the surface and letting if flow out through the bottom of the structure, trapping waste in a filter bag. The inventors have […]

The ozone layer is a protector of the earth from ultraviolet radiation from the sun. According to reports the ozone layer is getting smaller over Antarctica. The scientists are using satellites and sensors to get information on the measurements of the ozone layer. Since the early 20th century when the emissions of chemical substances called halo-carbons the ozone layer has […]

Heatwaves that used to arrive once every 20 years or so could become annual events by 2075 across almost two-thirds of the planet’s land surface – if humans go on burning ever more fossil fuels and releasing ever more greenhouse gases. Claudia Tebaldi, visiting scientist at the US National Center for Atmospheric Research, and Michael Wehner, senior staff scientist at […]

Scientists from the University of Delaware’s Bartol Research Institute in the Department of Physics and Astronomy have discovered very-high-energy gamma rays in the Cigar Galaxy (M82), a bright galaxy filled with exploding stars 12 million light years from Earth. The gamma rays observed by the team have energies more than a trillion times higher than the energy of visible light […]
