For the second-time ever, LIGO (Laser Interferometer Gravitational-Wave Observatory) detected gravitational waves from a neutron star collision. In fact, these particular gravitational waves were the result of a collision between the most massive neutron star pair ever witnessed.
This isn't LIGO's first encounter with gravitational waves. The observatory is famous for the first-ever detection of gravitational waves back in 2015, from a black hole merger. And then LIGO detected its first-ever gravitational waves from a neutron star merger in 2017, so this new 2019 data is only the second melding of neutron stars that’s ever been observed.
And with this second observation of neutron stars colliding, scientists can get some answers on how these cosmic events affect our universe.
Find out more about why this collision is particularly special; how LIGO documented it; and how knowledge surrounding cosmic events like this can help us better understand how our Earth came to be.

LIGO-Virgo Network Catches Another Neutron Star Collision
"On April 25, 2019, the LIGO Livingston Observatory picked up what appeared to be gravitational ripples from a collision of two neutron stars."
Gravitational-Wave Discovery Reveals Spectacular Crash of Neutron Stars, the 2nd Known
"For the second time ever, the Laser Interferometer Gravitational-Wave Observatory (LIGO) has spotted two ultradense stellar remnants known as neutron stars violently crashing together."
What are Gravitational Waves?
"Gravitational waves are 'ripples' in space-time caused by some of the most violent and energetic processes in the Universe."
