Scientists discover ultramassive black hole that now faces Earth
Space scientists in the UK have discovered a supermassive black hole 33 billion times the mass of Sun.

British media quoted the scientists from Durham University as saying that this is one of the biggest ever black hole found. The news about its discovery has been published in the journal Monthly Notices of the Royal Astronomical Society, and has been dubbed "extremely exciting", according to the outlet. This comes days after an international team of experts found that a supermassive black hole at the centre of a galaxy named PBC J2333.9-2343 has changed direction and is now aiming towards the Earth.

Astronomers believe that such massive black holes can be found at the centre of all large galaxies such as the Milky Way, which includes our own solar system.

Talking about the latest discovery, lead author Dr James Nightingale, of the Department of Physics at Durham University, said: "This particular black hole, which is roughly 30 billion times the mass of our Sun, is one of the biggest ever detected and on the upper limit of how large we believe black holes can theoretically become, so it is an extremely exciting discovery."

The black hole was discovered when scientists used gravitational lensing, where they took help from a nearby galaxy by converting it into a giant magnifying glass.

"Most of the biggest black holes that we know about are in an active state, where matter pulled in close to the black hole heats up and releases energy in the form of light, X-rays and other radiation. However, gravitational lensing makes it possible to study inactive black holes, something not currently possible in distant galaxies," said Dr Nightingale.

Metro said such ultramassive black holes are rare and elusive and their origins are unclear. Some experts believe they were formed when the universe was young and galaxies were merging with each other.

As many as three soldiers embraced martyrdom and one terrorist was killed in an exchange of fire between security forces and terrorists in Zarghun, the area of Balochistan on Saturday. According to the military’s media wing, the Inter-Services Public Relations (ISPR), an operation was launched in the area against suspected terrorists who attacked a security post. “Troops on the post retaliated readily to the fire raid thereby, pushing back the terrorists,” stated the military’s media wing. In the ensuing exchange of fire, three soldiers were martyred while one terrorist was also killed. The military identified the martyred soldiers as Sepoy Zaheer Ahmed, Sepoy Mudassir Shaheed and Lance Naik Abdul Qadeer.

Chief of Army Staff (COAS) General Asim Munir has said that the legal process of trial against planners, instigators, abettors and perpetrators involved in the May 9 mayhem has commenced under Pakistan Army Act and Official Secret Act as per existing and established legal procedures derived from the Constitution. The army chief's statement came as he visited Jinnah House and an army installation in Lahore, which were blatantly attacked and vandalised by “politically motivated” rioters, the Inter-Services Public Relations (ISPR) said in a handout. The COAS was also given a briefing on events of May 9 dubbed by the military as ‘Black Day’ — the day when Pakistan Tehreek-e-Insaf (PTI) supporters ransacked and torched military installations across the country following the arrest of their leader Imran Khan in a graft case. Addressing the garrison officers and soldiers at Corps Headquarters, Gen Munir emphasised that any action aimed at widening a gulf between people and the milita...
