What is a Giant Molecular Cloud? Well, first off, a molecular cloud is basically a cloud up in the space, and is composed mainly of molecular hydrogen and helium. And a Giant Molecular Cloud is a molecular cloud that is a hundred times the mass of our sun. It’s like about 100,000 suns can fit […]

The Milky Way is not the only galaxy existing in the vast universe. In recent years, more galaxies have been discovered. Our Solar System can be found on the Milky Way galaxy. The Milky Way galaxy is part of a group of about 30 to 35 galaxies in one neighbourhood and are collectively called as
When there is an enormous explosion in galaxies, there could be some flashes of gamma rays released. These flashes are called the gamma ray burst. In the universe, it is the most luminous event happening. The shortest periods a burst can last milliseconds. It can last up to several minutes as well. But the typical
Photo by: Beland Creative Commons Voids are those huge dimensions or sizes of space that have galaxies and groups of galaxies within its area or scope. A galaxy has plenty of stars, planetary bits and pieces, gas, dust and dark matter. Galaxies have millions or even billions of stars. The Sun is a part of
Do you know that the earth is part of the solar system which is part of the Milky Way galaxy within the Local Group that is in turn one of the components of the Virgo Supercluster? Amazing indeed, as everything in the universe is always a tiny component of a larger association of heavenly bodies,
There are many galaxies far away, and also near the solar system. Many are dwarves or even huge galaxies that stretch for miles, but one stands out and is considered as a major galaxy that has been studied from time to time, and this none other than the Small Magellanic Cloud.

Astronomical transit is the passage of a small astronomical body across the disk or face of a significantly larger body as opposed to an eclipse where significant occultation occurs. Note that the word refers to events where the nearer and smaller object actually appears significantly smaller instead of completely hiding the other.

Photo by: CWitte Creative Commons Virgo cluster is a group or clusters of galaxies in the universe. The cluster includes approximately 1,300 to 2,000 galaxies. Some are big while 90% of them are dwarf galaxies. These galaxies are attracted to each other by a common gravitational force. The Virgo cluster spans 15 million light years
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.
