BLACK HOLE BABY SPOTTED BEING BORN


For the first time, a black hole has been seen being born out of an exploding star 20 times the mass of our sun. The baby black hole is located 50 million light-years from Earth. IT has not been possible before to study a black hole anywhere especially from so close. In perspective the back hole was born almost in our backyard. What is important is that scientists have pinpointed its' birth date. The discovery is also important because it could help research the fates of other stars. Theoretically, stars that are greater than about 20 times the mass of our sun are thought to collapse inward and become neutron stars. Astronomers don't really know the dividing line between black holes and neutron stars,but the x-ray data will help narrow that down. Researchers prefer the baby black hole theory over the newborn neutron star, but only time and more data will tell.

I believe that this is a very significant event for astronomers that study the life span of all different kinds planets. They will be able to study the way plants end and what happens to them afterwards. They could use this knowledge to predict a similar fate for earth in the future. I will also help scientists study the importance and roles of black holes in the universe. They could also study the out come of the black hole that is in the middle of our universe. I believe that this is a big step in the study of astronomy.

Dark matter hunt deepens at Ont. mine


Researchers from Canada, the U.S. and Europe have recently set up new experiments at SNOLAB(Sudbury Neutrino Observatory), located two kilometres underground near Sudbury, Ont. they are trying to figure out the composition of dark matter — invisible mass that makes up at least 25% of the universe. To make dark matter show itself, They are using a four-kilogram dark matter particle detector,called the bubble chamber and running it remotely. Scientists think dark matter is made up of a theoretical type of subatomic particle called a weakly interacting massive particle (WIMP). WIMPs don't have any electrical charge and only interact with other particles by gravity. That makes them very difficult to detect. Physicists believe there are so many of these particles that, occasionally, they should crash into the nucleus of an atom and create a detectable signal. The problem is, the tiny, faint signal would be drowned out by the roaring din of signals generated by cosmic radiation at the surface of the Earth. That's why they are doing the experiment underground-the level of cosmic rays is reduced 10 millionfold

This is a great experiment on the same scale as the super-collider in switzerland. It must be an unbelievable facility and i would love to see the computers they are using. If the facility can prove the existence of dark matter it would be a great step forward in physics and Canada would be recognized internationally. I will follow this story with great interest.
