Spacetime — a creation of well-known actors?

Most physicists believe that the structure of spacetime is formed in an unknown way in the vicinity of the Planck scale, i.e. at distances close to one trillionth of a trillionth of a metre. However, careful considerations undermine the unambiguity of this prediction. There are quite a few arguments in favour of the fact that the emergence of spacetime may occur as a result of…

Tropical Cyclone Alcide’s rainfall observed by GPM Satellite

The Global Precipitation Measurement mission or GPM core satellite passed over the Southern Indian Ocean and analyzed the rainfall occurring in pre-season Tropical Cyclone Alcide. Tropical cyclone Alcide (03S), the first tropical cyclone of the 2018-2019 South-West Indian Ocean tropical cyclone season, has formed in the South Indian Ocean northeast of Madagascar. The Joint Typhoon Warning Center (JTWC) issued its first warning for 03S on…

Turbulence in space might solve astrophysical mystery

In addition to an electrically charged soup of ions and electrons known as plasma, space is permeated by magnetic fields with a wide range of strengths. Astrophysicists have long wondered how those fields are produced, sustained, and magnified. Now, scientists at the…

ASU geoscientists discover an overlooked source for Earth’s water

Where did Earth's global ocean come from? A team of Arizona State University geoscientists led by Peter Buseck, Regents' Professor in ASU's School of Earth and Space Exploration (SESE) and School of Molecular Sciences, has found an answer in a previously neglected source. The team has also discovered that our planet contains considerably more hydrogen, a proxy for water, than scientists previously thought. So where…

Johns Hopkins scientist finds elusive star with origins close to Big...

Astronomers have found what could be one of the universe's oldest stars, a body almost entirely made of materials spewed from the Big Bang. The discovery of this approximately 13.5 billion-year-old tiny star means more stars with very low mass and very low metal content are likely out there -- perhaps even some of the universe's very first stars. The star is unusual because unlike…
