The new time-lapse video shows 12 years of exoplanets orbiting their star

Credit: Northwestern University In 2008, HR8799 was the first exoplanet system ever to be directly imaged. Now, the famous system stars in its very own video. Utilization Notes Northwestern University astrophysicist Jason Wang has over the past 12 years collected amazing time-lapse video of a family of four. planets—each mass larger than Jupiter—orbits their star. … Read more

Physicists discover a new way to solve the strange mystery of dark energy

Physicists have proposed a new explanation for dark energy. It can shed insights into the interdependence between quantum field theory and general relativity theory, as two perspectives of the universe and its elements. What is behind dark energy – and what links it to the cosmological constant introduced by Albert Einstein? Two physicists from the … Read more

The first observation of de Broglie-McKinnon wave packets is made by exploiting a loophole in the 1980s theory

A new method for determining pressures in complex fluids

Lagrangian coherent structures (LCS) are mathematical structures used to predict the dynamics of fluid flows, from ocean currents to turbulent clouds on other planets. Arezoo Ardekani discovered that LCSs can also be applied to viscoelastic flows. Credit: NASA/JPL-Caltech/SwRI/MSSS Fluid dynamics researchers use many techniques to study turbulent flows such as ocean currents, or the swirling … Read more
