More and more rainfall extremes are observed in regions around the globe -- triggering both wet and dry records, a new study shows. Yet there are big differences between regions: The central and Eastern US, northern Europe and northern Asia have experienced heavy rainfall events that have led to severe floods in recent past. In contrast, most African regions have seen an increased frequency of months with a lack of rain.
Previously intractable problems for designing fusion experiments, improving weather models, and understanding astrophysical phenomena such as star formation will be more easily addressed without the need for expensive supercomputers using a new model identified at the University of Wisconsin-Madison.
The low pressure area formerly known as Tropical Cyclone Owen continued to organize and cross the southern Gulf of Carpentaria, Australia on Dec. 11. The Global Precipitation Measurement mission or GPM core satellite provided a look at the rainfall rates within the system.
A terahertz laser designed by MIT researchers is the first to reach three key performance goals at once -- high constant power, tight beam pattern, and broad electric frequency tuning -- and could thus be valuable for a wide range of applications in chemical sensing and imaging.
The effects of a supernova -- and possibly more than one -- on large ocean life like school-bus-sized Megalodon 2.6 million years ago are detailed in a paper just published in Astrobiology.
New work from the Carnegie Supernova Project provides the best-yet calibrations for using type Ia supernovae to measure cosmic distances, which has implications for our understanding of how fast the universe is expanding and the role dark energy may play in driving this process. The research was led by Carnegie astronomer Chris Burns.
Spectral observations made by the OSIRIS-REx spacecraft identified hydrated minerals across the asteroid, confirming that Bennu, a remnant from early in the formation of the solar system, is an excellent specimen for the OSIRIS-REx mission to study the composition of primitive volatiles and organics.
The remnants of Tropical Cyclone Owen have been lingering in the Southern Pacific Ocean for days. On Dec. 10, 2018 the storm finally appeared more organized on satellite imagery providing forecasters with a strong indication that it may be reborn as a tropical cyclone. NASA-NOAA's Suomi NPP satellite passed over the Gulf of Carpentaria and saw the storm.
Two new NASA research efforts delve into Hurricane Maria's far-reaching effects on the island's forests and on its residents' energy and electricity access.
Researchers have created tiny droplets of the ultra-hot matter that once filled the early universe, forming three distinct shapes and sizes: circles, ellipses and triangles.
