"Ferrari of space' yields best map of ocean currents
A satellite dubbed the "Ferrari of space" has yielded the most accurate model of ocean circulation yet, boosting understanding of the seas and a key impact of global warming, scientists said Tuesday.
Did the universe originate from a hyper-dimensional black hole?
Lately there's been news of a radical new theory proposing that the universe began from a hyper-dimensional black hole. Most of the reports seem to stem from an article posted a while back on the Nature blog, ...
Local model better describes lunar gravity
Two satellites orbiting the Moon as a part of NASA's Gravity Recovery and Interior Laboratory (GRAIL) mission have been mapping its inner structure by measuring subtle shifts in the pull of gravity on the ...
Lifetime of gravity measurements heralds new beginning
Although ESA's GOCE satellite is no more, all of the measurements it gathered during its life skirting the fringes our atmosphere, including the very last as it drifted slowly back to Earth, have been drawn ...
3D modeling of the Sun from the core to the surface
A team at the Astrophysics, Instrumentation and Modeling Laboratory (CEA/CNRS/Université Paris Diderot) has successfully modeled, in 3D, the effects of gravity waves in an extremely comprehensive simulation ...
Liquid spacetime: A very slippery superfluid, that's what spacetime could be like
What if spacetime were a kind of fluid? This is the question tackled by theoretical physicists working on quantum gravity by creating models attempting to reconcile gravity and quantum mechanics. Some of ...
Researchers find it would require 2.4 times less energy to create a black hole than thought
Large Hadron Collider experiments to present latest results at Moriond conference
Experiments at CERN's Large Hadron Collider (LHC) are set to present their latest results at the Moriond conference, which begins tomorrow in the Italian town of La Thuile, and runs until 16 March. Although all of the LHC ...
Black hole simulations on XSEDE supercomputers present new view of jets and accretion disks
Voracious absences at the center of galaxies, black holes shape the growth and death of the stars around them through their powerful gravitational pull and explosive ejections of energy.
GOCE's second mission improving gravity map
(Phys.org)—ESA's GOCE gravity satellite has already delivered the most accurate gravity map of Earth, but its orbit is now being lowered in order to obtain even better results.
Why won't the supernova explode?
(Phys.org) -- Somewhere in the Milky Way, a massive old star is about to die a spectacular death. As its nuclear fuel runs out, the star begins to collapse under its own tremendous weight. Crushing pressure ...
How do you say global business success? In English, says new research from Rotman School
English continues to reign supreme in international business, and it's not just because some of the biggest economies speak it.
Researchers create first large-scale model of human mobility that incorporates human nature
For more than half a century, many social scientists and urban geographers interested in modeling the movement of people and goods between cities, states or countries have relied on a statistical formula called ...
Martian carbon dioxide clouds tied to atmospheric gravity waves
On 4 March 1997 the Mars Pathfinder lander fell through the thin Martian atmosphere. During its descent, instrumentation aboard the lander recorded the changing atmospheric temperature, pressure, and density.
