Nasa discovers a new black hole in Milky Way

Nasa’s Swift satellite has found evidence of the presence of a previously unknown stellar-mass black hole in our Milky Way galaxy. Named Swift J1745-26 after the coordinates of its sky position, the nova is located a few degrees from the centre of our galaxy towards the constellation Sagittarius, Nasa said. While astronomers do not know its precise distance, they think the object resides about 20,000 to 30,000 light-years away in the galaxy’s inner region.

‘Ninja’ turtles to navigate the sea: A robotic sea turtle that features a large waterproof torso and can pack in a bunch of sensors is being developed by researchers to boost autonomous underwater navigation and rescue. The prototype unveiled at the Swiss Federal Institute of Technology is several feet long, mostly made of aluminium, and moves a metre per second.
