By Gabriel Popkin, Inside Science -- When leaders of the Laser Interferometer Gravitational-wave Observatory, or LIGO, announced in February the first-ever direct detection of a gravitational wave, astrophysicists Scott Ransom from the National Radio Astronomy Observatory and Andrea Lommen at Franklin and Marshall University in Lancaster, Pennsylva
Four institutions will become stewards of the observatory as it becomes an education center.
In December 2020, the Arecibo Observatory’s radio telescope was destroyed when a catastrophic cable failure caused its 900-ton platform to collapse onto the iconic dish below. Now, the National Science Foundation has named the stewards of the site’s future as an education center, marking the probable end of Arecibo’s astronomical research endeavors.
Pulsar timing arrays saw the first evidence for such a stochastic gravitational-wave background.
The Event Horizon Explorer would build on the work of the Event Horizon Telescope, which famously visualized a black hole in 2019.
