Observation of a 50-Solar-Mass Binary Black Hole Coalescence

This morning, the Laser Interferometer Gravitational-wave Observatory (LIGO) announced its third detection of gravitational waves emitted by two colliding black holes. The detection, named GW170104, was observed by LIGO on January 4, 2017 at 10:11:58 UTC with the two black holes having estimated masses of 31 and 19 solar masses. The final black hole’s mass is estimated to be around 50 solar…

How fine-tuned harmonies saves TRAPPIST-1 from destruction

Author: Dan Tamayo

In February of this year, a European-led team of astronomers announced that TRAPPIST-1, one of the 300 nearest stars to us, hosts seven Earth-like planets. Several of these could have the right temperatures to host liquid water, and are thus prime candidates in the search for life outside our solar system.

But a puzzle in the original paper was that when they tried to…

The TRAPPIST-1 Treasure Trove (Classroom Visit)

In February of 2017, astronomers announced an exciting development in our exploration of worlds beyond the solar system: not only do 7 Earth-sized planets orbit a nearby star known as TRAPPIST-1, but 3 of them may be able to support liquid water! To celebrate this discovery, the Canadian Institute for Theoretical Astrophysics and Discover t…

Anniversary of the Gravitational-Wave Discovery

Today, we celebrate the anniversary of gravitational-wave astronomy. One year ago, on September 14, 2015, LIGO made the first direct detection of gravitational waves – tiny, rippling distortions in space and time – that were emitted by the tumultuous, dramatic collision of two black holes. Since then, LIGO has confirmed the detections of two binary black hole mergers (maybe even three!), and wit…

Second Detection of Gravitational Waves

On December 26, 2015 at 03:38:53 UTC, the twin detectors of the Laser Interferometer Gravitational-wave Observatory (LIGO) observed gravitational waves produced by the collision of two stellar-mass black holes. The black holes that emitted these waves are inferred to have masses of 14 and 8 solar masses, and the final black hole has a mass of 21 solar masses. This event, named GW151226,…
