“This is a symptom of Japan’s population decline,” said Jeffrey Hall, a lecturer at Kanda University of International Studies in Chiba. “It’s not really a problem of building too many houses” but “a problem of not having enough people,” he said. According to figures compiled by the Ministry of Internal Affairs and Communications, 14% of all residential properties in Japan are vacant. “When an earthquake or a tsunami occurs, there is a possibility that vacant houses will block evacuation routes as they break down and get destroyed,” he said. In other rural areas with a high concentration of vacant houses, akiya have stalled development, the professor said.

☆ Scientists capture first direct image of a supermassive black hole, 6.5 billion times the size of the sun, spewing out jets of plasma

The jets were captured being released from a black hole 6.5 billion times the size of our sun. The image is the first to connect the jets to the edge of the supermassive black hole. The black hole, located at the center of the M87 galaxy 55 million light-years away, is around 6.5 billion times bigger than our sun. Black holes don't only swallow matter, they sometimes shoot it outMost galaxies, including our own, swirl around a supermassive black hole. Material swirling around a black hole needs to lose speed and energy before it can fall inwards.

[1/2] This image shows the jet and shadow of the black hole at the center of the M87 galaxy together for the first time. The supermassive black hole pictured resides at the center of a relatively nearby galaxy called Messier 87, or M87, about 54 million light-years from Earth. This black hole, with a mass 6.5 billion times that of our sun, was the subject of the first image of such an object ever obtained, released in 2019, with another black hole pictured last year. Seeing the entire scene in the vicinity of a supermassive black hole can be insightful. The EHT project has yielded the images of the two supermassive black holes.

By observing its subject at slightly longer radio wavelengths, the team was able to bring into visibility the cooler outer regions of the black hole’s fiery accretion disk, from which the jet seems to emanate. “We know that jets are ejected from the region surrounding black holes,” Dr. Lu said in a statement issued by the European Southern Observatory. “But we still do not fully understand how this actually happens. To study this directly we need to observe the origin of the jet as close as possible to the black hole.”In the meantime, the Event Horizon Telescope team is gathering resources for more observations, with the goal of making a black-hole movie. We will be able to film how the matter falls into a black hole and eventually manages to escape.”
