The first tropical depression of the Eastern Pacific hurricane season formed during the early morning of Thursday, May 28, 2015, well southwest of Mexico. An image of the storm taken from NOAA's GOES-West satellite shows the depression in infrared light as it was born in the early morning hours before sunrise.
In the most extensive survey of its kind ever conducted, a team of scientists have found an unambiguous link between the presence of supermassive black holes that power high-speed, radio-signal-emitting jets and the merger history of their host galaxies. The results lend significant weight to the case for jets being the result of merging black holes and will be presented in the Astrophysical Journal.
Astrophysicists have developed a new method for calculating the effect of Rayleigh scattering on photons, potentially allowing researchers to better understand the formation of the Universe.
When you're blasting though space at more than 98 percent of the speed of light, you may need driver's insurance. Astronomers have discovered for the first time a rear-end collision between two high-speed knots of ejected matter. This discovery was made while piecing together a time-lapse movie of a plasma jet blasted from a supermassive black hole inside a galaxy located 260 million light-years from earth.
This week from AGU: NASA Earth science, Climate change music and Tibetan Plateau evolution.
Do microbes grow differently on the International Space Station than they do on Earth? Results from the growth of microbes collected by citizen scientists in Project MERCCURI indicate that most behave similarly in both places.
A study, published today in Nature, implies that the global climate is on the verge of a broad-scale change that could last decades. The change is likely to bring drier summers to Britain and Ireland, accelerated sea-level rise along the northeast coast of the USA, and drought in the Sahel region. This new phase could also offer a brief reprise from the rise of global temperatures, as well as fewer hurricanes hitting the USA.
Using ever more energetic lasers, Lawrence Livermore researchers have produced a record high number of electron-positron pairs, opening exciting opportunities to study extreme astrophysical processes, such as black holes and gamma-ray bursts.
Astronomers have discovered a disc of planetary debris surrounding a young sun-like star that shares remarkable similarities with the Kuiper Belt that lies beyond Neptune, and may aid in understanding how our solar system developed.
A collaboration of physicists and a mathematician has made a significant step toward unifying general relativity and quantum mechanics by explaining how spacetime emerges from quantum entanglement in a more fundamental theory.
