Feature Guest: Michael Landry
The alchemists never did succeed in turning elements into gold and silver, and now we know why. It takes the merger of two neutron stars to produce these and other precious metals. That was the headline just two weeks ago when astronomers reported the first ever detection of gravitational waves from this so-called kilonova event. With this discovery we enter a new era. Today we’re joined here at The Star Spot by Dr. Michael Landry, head of the LIGO observatory at Hanford where this landmark discovery was made, to discuss the dawn of multi-messenger astronomy.
Current in Space
The original of high energy cosmic rays is still a mystery, but now Tony reports that the answer may be more far out - literally - than we imagined. Then Maya has an important lesson for us: don’t judge a book by its cover, or a planetary interior by its surface. And as we gaze up at the moon in our sky, Dave wonders if the moon once had skies of its own.
About Our Guest
Dr. Michael Landry is Detection Lead Scientist at the LIGO, the Laser Interferometer Gravitational-Wave Observatory, in Hanford, Washington. The LIGO observatories have been responsible for the first ever discoveries of gravitational waves, for which the Nobel prize in physics was recently awarded. Landy is also a physicist at the California Institute of Technology. He earned his PhD at the University of Manitoba in strange quark physics and performed graduate work at TRIUMF, Canada’s national laboratory for particle and nuclear physics, as well as Brookhaven National Laboratory in the United States.
