There are three states of matter we are familiar with: solid, liquid, and gas. We don?t even need to define them anymore; their names are their definitions. But there?s the fourth state of matter which many aren?t too knowledgeable about (some may not even know there?s such a thing). It?s called plasma or ionized gas.
The science of spectroscopy paves the way for the classification of stars according to their spectral types, or the result of their specific spectra. You can tell a lot by breaking down a star’s light. In order to understand spectral types, let us go a little into the science of spectroscopy, or breaking down a
If you ever wondered how you can determine the elements that make something up, you can do that by subjecting your sample to spectral analysis. This involves breaking it down into its spectrum to determine its chemical composition and properties. Spectral analysis is commonly used to find out the composition of unknown materials and utilize
A spiral galaxy is so-called because of how it looks: with arms extending from its center. Upon closer inspection, you may find that the spiral galaxy actually looks like a pinwheel, with its arms going out from the central cluster of stars.
A Trojan, in Astronomy, is a minor planet or moon that shares an orbit with a larger planet or satellite but does not collide with the larger planet because while it orbits, it stays safely in what is called as the Lagrangian points. In theory, there are also Trojan planets that may reside at Trojan
Astronomical seeing is that blurring and twinkling phenomena of various astronomical objects such as stars, which is naturally caused by the turbulent mixing activities in the Earth’s atmosphere that then varies the optical refractive index. Such conditions on any given night and locations signifies how the Earth’s atmosphere disturbs the images through the telescopes.

Globular clusters are vast swarms of stars, up to a hundred thousand or more, which were formed through time. Tightly bound up by gravity, globular clusters are spherical in size. The stars in a globular cluster are red giants, much older than our Sun or our Solar System. Each globular cluster can contain hundreds of
The heliosphere is the protective layer surrounding the sun. It is like a bubble in space that is basically produced by solar winds. Solar wind is composed of particles, ionized atoms and magnetic field. This wind streams off of the Sun at the speed of about 400 km/s. This speed will start to slow down
The flow of neutral or charged gas ejected from a star’s upper atmosphere is referred to as the stellar wind. It is distinguished by the less collimated bipolar outflow characteristics of a young star. However, stellar winds are not spherically symmetric.
What happens when a supernova explodes? What is left is what we know as the supernova remnants or SNRs. They are extremely important to expand the understanding of the galaxy and the universe beyond. According to scientists, supernova remnants have greatly affected galactic ecology of the Milky Way. It is believed that if not for
