Powerful New Technique to Measure Asteroids' Sizes and Shapes

A team of French and Italian astronomers have devised a new method for measuring the size and shape of asteroids that are too small or too far away for traditional techniques, increasing the number of asteroids that can be ...

Black Holes Lead Galaxy Growth

(PhysOrg.com) -- Astronomers may have solved a cosmic chicken-and-egg problem -- the question of which formed first in the early Universe -- galaxies or the supermassive black holes seen at their cores.

Using small black holes to detect big black holes

An international team of astrophysicists with the participation of the University of Zurich proposes a novel method to detect pairs of the biggest black holes found at the centers of galaxies by analyzing gravitational waves ...

Can quantum particles mimic gravitational waves?

When two black holes collide, space and time shake and energy spreads out like ripples in a pond. These gravitational waves, predicted by Einstein in 1916, were observed for the first time by the Laser Interferometer Gravitational-Wave ...

Gravitational wave, Venus missions get European green light

The European Space Agency gave the green light to two missions on Thursday, one to detect ripples in spacetime called gravitational waves and another to probe the secrets of Earth's closest neighboring planet Venus.

LIGO surpasses the quantum limit

In 2015, the Laser Interferometer Gravitational-Wave Observatory (LIGO), made history when it made the first direct detection of gravitational waves—ripples in space and time—produced by a pair of colliding black holes.
