This article is all about information about black holes. They tell you in detail what black holes are and what they do. It tells you all you would need to know about black holes.

There are three kinds of black holes. The three types are stellar, supermassive, and miniature black holes. My favorite black hole is the supermassive black hole because it is the largest black hole. A supermassive black hole is a black hole with the largest of its type in the galaxy, on the order of hundreds of thousands to billions of solar masses. Most, if not all galaxies, including the Milky Way, are believed to contain supermassive black holes at their centers. Facts about black holes:Black holes emit x-ray radiation and get smaller and smaller until they disappear, or "evaporate",The gravity around the "hole" of a black hole is so strong that NOTHING can make its way back out after a critical distance, and Most black holes are formed from the death of large stars (larger than the sun) that run out of fuel and cannot sustain its nuclear reaction. Fictional facts: that they suck things in, and they dont have a mass.

I think that this blog topic was very interesting because black hole are very cool to learn about. There is so much information on them. Black holes are fun to learn about. I wish black holes were real in life becasue they suck things in and dont get big. But im glad I learned about black holes!


Some fiction facts about black holes are Astronomers think that at least one black hole is born every day, and

This atricle is about what the international year of astronomy is. It also talks about information you need to know about it. It tells you what people do durning the International Year of Astronomy.

Its called the International Year of Astronomy because it is to commemorate the
400th anniversary of Galileo's first celestial observations using a telescope. United Nations Educational, Scientific, and Cultural Organization (UNESCO) and the U.N. General Assembly are all sponsoring it. Over 100 countries are participating in it. People will be In this event, people will take there telescopes and point them at the same celestial wonders galilo pointed to 400 years ago durning the Galilean nights.


I believe the International Year Of Astronomy is really interesting. Space has a great impact on our earth and Galileo showed us that. Im not really that into space and telescopes. But this is really interesting.
