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.
The object is revolving around the sun in the vicinity of Jupiter but in the opposite direction from most other celestial bodies, according to a study featuring a Brazilian scientist as co-author. Through a computer simulation, the study shows that the orbit has been stable since the giant planets were formed.
The final bulletin on Tropical Cyclone Sagar was issued at 11 a.m. EDT (1500 UTC) on May 19. By that time, Sagar had made landfall in Somalia. NASA's Terra satellite captured an infrared image of the storm as it was making landfall.
A new study has discovered the first known permanent immigrant to our solar system. The asteroid, currently nestling in Jupiter's orbit, is the first known asteroid to have been captured from another star system. The work is published in Monthly Notices of the Royal Astronomical Society: Letters.
Tropical Cyclone Sagar, formerly known as 01A, appeared more organized on satellite imagery and has strengthened since May 17.
