Nothing is suppose to escape from a black hole???

From inside the event horizon. Star didn't make it inside.

As humankind's ancestors were learning to walk upright, a star was launched from the supermassive black hole at the center of our galaxy at a staggering 3.7 million mph (6 million km/h).

Five million years after this dramatic ejection, a group of researchers, led by Sergey Koposov of Carnegie Mellon University's McWilliams Center for Cosmology, has spotted the star, known as S5-HVS1, in the Crane-shaped constellation Grus. The star was spotted traveling relatively close to Earth (29,000 light-years away) at unprecedented, searing speeds — about 10 times faster than most stars in our galaxy.

"The velocity of the discovered star is so high that it will inevitably leave the galaxy and never return," Douglas Boubert, a researcher at the University of Oxford and a co-author on the study, said in a statement.

Physicists from across Europe have revealed plans for a huge underground gravitational-wave observatory that, if funded, could be operational by the mid-2030s. The European Laboratory for Gravitational and Atom-interferometric Research (ELGAR) could be located in either France or Italy and would cost around €200m to build. Those involved in the project have now applied for European funding to carry out a detailed design and cost for the facility.

Gravitational waves are ripples in space-time that were predicted over 100 years ago by Albert Einstein. In 2015 the twin Advanced Laser Interferometer Gravitational-wave Observatory (aLIGO) in the US along with the Virgo gravitational-wave detector in Italy detected the first gravitational-wave signal and since then tens of such events have been spotted. The observation and pinpointing of such gravitational waves is expected to be boosted in the coming years by the recent completion of Japan’s KAGRA observatory, which is the world’s first underground gravitational-wave observatory to use cryogenic mirrors.

Virgo and one of the LIGO detectors have seen for the first time a black hole-neutron star merging. The other LIGO detector was temporarily out of commission. The event must still be confirmed by data analysis.

Nobel Prize in Physics. Half to Roger Penrose, UK, for his 19791970 paper with Stephen Hawking which demonstrated that black holes are a logical consequence of General Relativity, The other half to Reinhard Genzel, Germany, and Andrea Ghez, USA, for demonstrating the existence of a massive black hole at the center of our Galaxy. Congratulations to Roger Penrose. I have a hard copy letter from him, partly handwritten.
