First observation of merger of two neutron stars

Neutron stars are the remnants of explosions of supernovae. Neutron stars are most dense in the universe so these are quite small in size. For example the size of London. They are so dense that a spoonful of neutrons weighs as much as 100 000 Eiffel towers. It so happens that when two neutron stars approach each other, they turn faster and faster generating the gravitational waves by modifying the space-time around them. Ultimately they collide and fuse. After this the eject lots of matter. How such events in occuring in the universe are detected?

The department has converted a small portion of the forest into a Nature Park. I am a regular visitor to this park where sometimes very different birds make their appearance. One day, I was lucky to spot this beauty perched on the branch of a leafless tree. It was sitting very patiently perhaps inviting me to take as many pictures as I liked. I took so many pictures. When I processed them, I had some confusion between Eurasian Hobby and Peregrine Falcon because the former was spotted… Read More »Shaheen Falcon

He sent 50 pages of French author Claude Simon’s 1962 novel ‘The Palace’, set during the Spanish civil war, to 19 French publishers touting it as fresh material to be considered for publication. The submission was rejected by 12 publishers outrighly, while seven never replied despite the fact that Simon won the Nobel prize for literature in 1985. One editor claimed in a rejection letter that the book’s “endlessly long sentences completely lose the reader”, and that it failed to have a “real plot with well-drawn characters”. Simon is… Read More »DEGRADING STANDARDS IN PUBLISHING
