Scientists plan to use colliding black holes to measure how fast universe is expanding

Next to nothing can escape the strong gravitational pull of a black hole but now scientists are planning to use the collisions of black holes to understand the age of the universe and its evolution. In a new study published in Physical Review Letters, University of Chicago astrophysicists have developed a method for using pairs … Read more

Why our earthly days are getting longer |  Life

At the moment days are getting longer and we don’t know why. The Earth is taking a bit longer to rotate on its axis. We have known for decades that the speed at which our Earth spins varies. For example, on Boxing Day, 2004, there was a huge earthquake in the Indian Ocean. A 1,500 … Read more

If you want to make a comet, asteroid, planet, star, or many other bodies, the recipe is the same. There is just one ingredient: the cosmic clouds of gas and dust. The procedure is the same; one just gathers some of the material into a lump. What you end up with is entirely determined by … Read more

Hubble telescope finds star from 12.8 billion years ago |  Life

The image does not look very impressive, just a faint, somewhat blurry dot. However that dot is an image of the oldest and most distant individual star we have ever seen. Its light has taken 12.8 billion years to reach us. Since the universe is around 13.7 billion years old, we are seeing a star … Read more
