Heartbeat of supermassive black hole 600 mn light-years away still strong a decade after discovery

Astronomers have confirmed that the heartbeat of a supermassive black hole under study is still going strong after ten years since its discovery.As per a BBC report on the finding, astronomers have said this is the longest-living heartbeat ever seen in a black hole, adding that it could help scientists deduce more about its size and the space surrounding it.The "heartbeat" of the black hole in question was first discovered in 2007, at the centre of a galaxy dubbed RE J1034+396 around 600 million light-years from Earth.[caption id="attachment_8469581" align="alignnone" width="1280"] A black hole including the heartbeat signal observed in 2007 and 2018.

The study's findings were published in the journal Monthly Notices of the Royal Astronomical Society.It claims that the signal from this galactic giant repeated every hour, in a pattern that was observed in several snapshots before the object was blocked by the Sun in 2011.[caption id="attachment_8469571" align="alignnone" width="1280"] XMM-Newton (a.k.a the High Throughput X-ray Spectroscopy Mission and the X-ray Multi-Mirror Mission) is an X-ray space observatory launched by the European Space Agency in 1999.

To the scientists' amazement, the heartbeat could still be detected."This heartbeat is amazing!” lead author of the study Dr Chichuan Jin of the National Astronomical Observatories, Chinese Academy of Sciences, told Durham university press. "It proves that such signals arising from a supermassive black hole can be very strong and persistent. It also provides the best opportunity for scientists to further investigate the nature and origin of this heartbeat signal."
