The Laser Interferometer Gravitational Wave Observatory (LIGO) detects the ripples in space-time by using a device called laser interferometer, in which the time it takes light to travel between ...

In about 11 years, one of humankind’s most ambitious missions is set to launch into space. Decades in the making, the Laser Interferometer Space Antenna, or LISA, could revolutionize our understanding ...

One of the hardest things to calculate for an asteroid is its mass—but it is such a critical feature. It determines how much of an impact it would have if it hits something, or how many resources are ...

When we think of physics experiments, we tend to envision cavernous rooms filled with things like optical benches, huge coils in vacuum chambers, and rack after rack of amplifiers and data acquisition ...

LISA is set to revolutionize our understanding of the gravitational universe and the interactions that make the entire cosmos turn. Reading time 6 minutes LISA, a $1.6 billion gravitational wave ...

Before an ESA mission reaches the launch pad, it has to go through a number of approval procedures that ensure the mission’s readiness. The future space-based gravitational wave observatory, the Laser ...

After seven years of upgrades, the Advanced Laser Interferometer Gravitational Wave Observatories were dedicated on Tuesday at the LIGO Hanford facility near Richland, Washington. Limited time: Save ...

A quantum trick based on interferometric measurements allows a team of researchers at LMU to detect even the smallest movements of a laser beam with extreme sensitivity. Precisely measuring minute ...
