Star Clusters

By Colin Jones Astronomy is the study of the galaxies. Some astrologers practice it as a serious science while for others it is an educational hobby. For this reason, whenever an astronomy picture of the day is offered to the general public, people usually jump at the chance of looking at it. There are plenty of astronomical pictures to choose from, and plenty of interesting celestial objects to keep people enthralled. NASA of course is a primary source for an astronomy picture of the day. This site NASA.gov shows a new image each and every day. There's also another section that shows video footage. ...

Astronomy is the study of the universe. It is a serious science, but also a very pleasurable hobby. Therefore, whenever an astronomy picture of the day is offered to people, they usually accept it. There are plenty of such pictures to choose from, and plenty of interesting objects out there to keep people looking. Of course ,NASA is one of the primary sources for an astronomy picture of the day. This site, NASA.gov, shows a new photo each and every day. There is also a section that shows videos. These could be used to create your own photo site. For example, Saturn’s moon Enceladus ... Read Full Story

Our solar system is located nearly 25,000 light-years from the center of our Milky Way galaxy. We now know that we live in a spiral galaxy, consisting of billions of stars, and that our galaxy is just one of hundreds of billions of galaxies in the universe. However, the location of our Sun in the Milky Way, the size of our galaxy, the number of stars in it, and its structure were all unknown just 100 years ago. During the early 20th century, astronomers were trying to answer these questions using a variety of techniques. You will use one such method to determine the ... Read Full Story

Stars always evolve in the universe in large groups, known as clusters. Astronomers distinguish these formations by their age and size. The question of how star clusters are created from interstellar gas clouds and why they then develop in different ways has now been answered by researchers at the Argelander Institute for Astronomy at the University of Bonn with the aid of computer simulations. The scientists have solved -- at least at a theoretical level -- one of the oldest astronomical puzzles, namely the question of whether star clusters differ in their internal structure. Astronomical observations have shown that all stars are formed in ... Read Full Story

One of the galaxy's most massive young star clusters is revealed in a stunning new image from the Hubble Space Telescope. The cluster of thousands of stars lies 20,000 light years from Earth in the Carina spiral arm of our galaxy. It is embedded in a star-forming nebula called NGC 3603, a cloud of gas and dust with enough material to form 400,000 stars like the Sun. Watch a video zooming in on the star cluster's location in the sky by clicking on the image at right. Most of the bright stars in the image are very hot and massive. Their radiation and stellar ...

NASA's Chandra X-ray Observatory and optical telescopes revealed a dark matter core that was mostly devoid of galaxies, which may pose problems for current theories of dark matter behavior.
