Washington, Apr 10: Scientists released the much-awaited first direct image of a massive black hole at the centre of Messier 87, a galaxy which is about 54 million light-years away, at the National Press Club here on Wednesday. 

The image has been taken by the Event Horizon Telescope (EHT), which is a network of 10 radio telescopes spread across the planet, according to The Washington Post. The telescope functioned as if it is a single receiver, tuned to high-frequency radio waves, to take the image. 

The picture - released at six simultaneous news conferences on Wednesday - shows the event horizon, which is the boundary between light and dark around a black hole. A doughnut-like body can be seen in the portrait, which scientists say is the dark silhouette of the black hole against the hot, glowing material that surrounds it. 

"We are able to image one more object in the universe that ... at one point people thought could not be possible. It hits that human explorer spirit. We got another look into the unknown," Feryal Ozel, a member of the science council for the EHT said, calling the occasion her career's highlight.
 
The shape of the black hole matches what theorists had predicted ever since they started wrestling with Albert Einstein, General Theory of Relatively over a hundred years ago, reports The Washington Post. 

The European Commission hailed the occasion as a "paradigm shift" adding, "This major scientific achievement marks a paradigm shift in our understanding of black holes, confirms the predictions of Albert Einstein's General Theory of Relativity and opens up new lines of enquiry into our universe."

Mangaluru, May 3: The Mangaluru City Corporation will resort to water rationing from May 5 as the Thumbe vented dam, which supplies drinking water to the city, is facing a shortage in water storage.

Instead of daily supply, water will be supplied on alternate days, the Executive Engineer (Water Supply) at the corporation said in a release.

The release said that water will be supplied to Mangaluru City North on May 5. There will be no water supply to Mangaluru City North on May 6. Instead water will be supplied to Mangaluru City South on May 6. Likewise the supply on alternate days will continue.

The inflow in the Netravathi has stopped, the release said, requesting people to cooperate with the corporation and not waste water for washing vehicles and other purposes.

An engineer at the corporation said that water level at the dam stood at 4.27 m on Wednesday against the full storage level of 6 m. If water is supplied daily to the entire city (Mangaluru City North and Mangaluru City South) the existing storage will last only for 16 days, the engineer said. Hence the decision to supply water on alternate days has been taken to supply water till May-end.

Madikeri, May 11: Kodagu police have apprehended the man allegedly responsible for the brutal murder of a minor girl within the confines of Kumbaragadige village in Karnataka's Somwarpet taluk. 

Kodagu Superintendent of Police, K Ramarajan, disclosed that the arrested individual is Prakash (32) from Hammiyala village in Somwarpet taluk. However, authorities are still in the process of recovering the severed head of the victim. The perpetrator had absconded with the victim's severed head after committing the crime. 

Search operations for the suspect commenced late on Thursday night (May 9), with officials diligently pursuing leads. Acting on information suggesting the suspect's presence in a forested area near the village, the police swiftly moved in and apprehended him.

The victim US Meena, 15, a student of Surlabbi High School, had passed the SSLC examinations, the results of which were announced on May. One same day, she was murdered. 

Reportedly, the engagement of the minor girl with the suspect was thwarted by officials from the Women and Child Development department. Subsequently, officials persuaded the girl's parents against proceeding with the marriage. 

However, despite these interventions, the suspect forcibly entered her residence during the night, purportedly abducted her, and later perpetrated the heinous crime in a wooded area on the outskirts of the forest, before absconding with her severed head.
