The universe is a big place to explore, and as we learn more about it, the questions will continue to flow! The position of a star in the diagram provides information about what stage it is in, as well as its mass and brightness. Chatty, open-ended questions diminish the usefulness of our site and push other questions off the front page. These can be detected on Earth using very delicate instruments at the LIGO observatory.

Introductory Astronomy: Old Test Questions. Edited and updated by Carolyn Collins Petersen. When do the planets in our solar system all line up? 8 Answers. As they evolved and died, they created heavier and heavier elements, which formed second- and third-generation stars and their planets. Our universe is now 13.8 billion years old and measures 92 billion light-years across. It was not an explosion (as is often depicted in some artwork) but more of a sudden expansion from a tiny pinpoint of matter called a singularity.

Over the last few weeks people have been sending their questions in to the Cosmic Comics astronomy expert. Direct observation (by sampling or remotely) is mostly limited to a thin layer around the solid surface of the Earth, and physical experimentation is limited to the pressures of the uppermost layers of the planet. Do all objects in the universe exert force on all other objects? Why do the spikes that shoot out of stars form perfect crosses? Astronomers classify stars and assign "types" to them. Some of the unsolved problems in astronomy are theoretical, meaning that existing theories seem incapable of explaining a certain observed phenomenon or experimental result. It was really the beginning of the expansion of space and time, from a small point that contained the entire universe. How often does the sun's magnetic field flip? I need an open-ended question for astronomy that has many different answers!? Certainly, it's a very energetic event and would give off a lot of radiation.

The study of stars' lives and how they are born, live, and die is called "stellar evolution", and involves looking at many types of stars to understand their life cycles. Why don't galaxies have a natural magnetic field like the earth does? How long before the expansion of the universe causes our earth to drift away from the sun? Most depictions of the beginning of the universe show it almost as an explosion. The legal definition of space is that it begins at the top of the atmosphere. This portrait of Stephan's Quintet, also known as Hickson Compact Group 92, was taken by the new Wide Field Camera 3 (WFC3) aboard NASA's Hubble Space Telescope. Our Sun is properly classified as a yellow dwarf. From that beginning, the universe has expanded and grown more complex.
