I found an interesting article entitled Precise Location, Distance Provide Breakthrough in Study of Fast Radio Bursts. The article talks about how with new technology astronomers can pinpoint locations of various things like stars, planets and what ever else is there. The new system is called Fast Radio Burst (FRB). FRB sends radio waves up into space. The pulses can then be used to locate things in space. Many people are still trying to understand exactly how it works and what this means going forward. They have had many tests done throughout the years but their were also times when it was quite with no readings. The challenge has been understanding exactly what they receive back and how to interpret the data since it is so new.
This article relates to our objective because we talked about how astronomers can determine information about a star, like distance, size, and mass. In class we saw, using our fingers, how when and object is close it seems to move more, but when an object is far away, it appears to move less. Using this idea scientists are able to track stars movement. Stars are also categorized into different groups depending on there magnitude, but actual and apparent. Magnitude will tell the distance away the star is. Once that is determined, size can be calculated. Tracking a star will help determine radius which is needed for size. In addition, temperature can be calculated because temperature and manganite are connected. Once temperature and the radius is known, using a constant variable, the size of the star can figured out. Mass is determined based on luminosity. The more energy a star has, the bigger the mass. To help understand all of this, we looked at some PowerPoint slides and worked on a few pages in our workbook.
What I found interesting about this article is the fact that radio waves can be used. We talked a lot about telescopes and how that relates to wavelengths. But to learn that radio waves can be used to pinpoint an exact location is pretty cool. I am amazed everyday how technology is changing the way we can see and learn things about space.
