The Astronomy Cast official web site also hosts the blog Astronomy Cast STAY , which covers select astronomy meetings using various bloggers, including Fraser Cain, Dr. Pamela L. Homosexual, and Phil Plait as well as latest astronomy-associated news and occasions. A public discussion board , the Astronomy Cast Discussion board , where registered members and website guests could share and exchange helpful data will also be found on the web site and is created below Dangerous Astronomer and Universe Right now Forum Provides you the place and predicts visibility of man-made satellites, including the House Shuttle, Worldwide House Station (a must-see), and Hubble Area Telescope.
Years later, when we were again at Horana (my dwelling town in Sri Lanka, 40km inland from Colombo) I managed to convince my friend’s father to assemble his dusty telescope. We only noticed the craters on the moon that evening, not Saturn or every other such object. I used to be in my early 20s when I owned my first telescope. In 2006, I managed to film a lunar eclipse with my video camera however it was definitely not one of the exotic objects I was so fascinated with.
In preparation for iCHSTM 2013, I’ve spent the previous few weekends indulging my artistic side. Sawing and submitting wooden and brass into a disc, ring and pointer may have disturbed the peace of my neighbours’ Saturday afternoons, but it has meant I can display a particularly ingenious, user-pleasant medieval machine: a planetary equatorium. We acquired to the purpose the place we have been getting fairly an extended following, fairly early on, actually. I might say by March, Google reached out to me and said, “That is actually attention-grabbing. We’d prefer to showcase what you’re doing.”
Pamela: What’s cool is there’s basically this rain of particles. In the event you collide collectively two electrons, they create a bathe of recent particles which might be initially unstable. These unstable particles will collapse into extra particles, and if any of those are unstable, they will collapse into more particles. As they do that, they’re raining out of the target chamber, where the collision took place, and passing by means of various kinds of gasses and crystals. They interact with the material within the detector and sometimes give off faint sparkles of sunshine.
Your last equation doesn’t work both. Firstly you are figuring out the energy of the force between two universe sized masses a few universe radius aside (which is not the gravitational pressure as we normally define it – because the pressure on a unit mass to make things easier). Secondly – Newtons are outlined as kg/(m/s^2). The items to your calculation are kg/(ly/s^2) so any settlement in magnitude is sheer coincidence. For those who multiply it by the mass of the universe you get about 1e44 which makes me suppose you did the unit conversion proper?
