Visible satellite imagery from NASA's Aqua satellite revealed that Tropical Cyclone 02A, now renamed Mekunu has continued to consolidate and organize off the coast of Oman in the Arabian Sea.
By the late 21st century, if atmospheric greenhouse gas concentrations reach worst-case projections, Floridians could experience summer heatwaves three times more frequently, and each heatwave could last six times longer and be much hotter than at present, according to Meteorology Professor Shawn M. Milrad of Embry-Riddle Aeronautical University.
A team of astronomers has performed one of the highest resolution observations in astronomical history by observing two intense regions of radiation, 20 kilometers apart, around a star 6,500 light-years away. The observation is equivalent to using a telescope on Earth to see a flea on the surface of Pluto.
Based on new observational data, an international team led by astronomers at ETH Zurich identified at least six candidates for dark galaxies -- galaxies that have a few (if any) stars in them and are, for that reason, notoriously difficult to detect with current instruments.
Magnetometer network identifies magnetic field disturbances that can cause interference in electronic appliances, power grids and satellite navigation systems. Using the data collected by the network, Brazilian researchers work on the development of a specific magnetic K-index for South America.
Tropical Cyclone 02A formed about 655 nautical miles south of Masirah Island, Oman. When NASA's Aqua satellite passed over the Arabian Sea, Northern Indian Ocean and captured a visible image of the newly developed storm.
For close to two weeks the combination of a nearly stationary front and tropical moisture caused almost continuous precipitation over much of the Mid-Atlantic. Using data from a constellation of satellites, NASA calculated the extreme rainfall that occurred in parts of the US.
Asteroid 2015 BZ509 is the very first object in the solar system shown to have an extrasolar origin. This remarkable discovery was made by CNRS researcher Fathi Namouni and her Brazilian colleague Helena Morais, and is published on May 21, 2018, in MNRAS.
NASA and private company SpaceX plan to send humans to Mars within the next 15 years--but need to figure out how to protect astronauts from the dangerous cosmic radiation of deep space. Now the lab of UCSF neuroscientist Susanna Rosi, PhD, has identified a potential treatment for the brain damage caused by cosmic rays--a drug that prevents memory impairment in mice exposed to simulated space radiation. The study was published May 18, 2018 in Scientific Reports.
Hurricane Patricia, which battered the west coast of Mexico in 2015, was the most intense tropical cyclone ever recorded in the Western Hemisphere. Amid the extreme violence of the storm, scientists observed something new: a downward beam of positrons, the antimatter counterpart of electrons, creating a burst of powerful gamma-rays and X-rays.
