Stars go through various phases of its existence. No one knows for sure how stars are formed, but astronomers theorize that they first come into birth as a nebula, and they finally end their lives as a neutron star, otherwise known as a white dwarf. Thereafter, they are assumed to to form part of a […]
The word intergalactic in astronomy may mean different things. It can be associated to travel, mediums, or space itself. From the word itself, the prefix ?inter-? means in between or across, and ?galactic? means galaxy. Basically, the term means between galaxies, and it may be an interaction or other activity when two galaxies meet and
Interstellar is attached to many other words, like the terms intergalactic and interplanetary. It literally means between or among stars, and is defined as an adjective in the English language. The term can also pertain to space clouds, matter in outer space or a specific study in astronomy. Interstellar cloud is a generic name for
A Lenticular galaxy is basically a kind of galaxy which borders in between an elliptical and spiral galaxy when classified. They are shaped like a disk, and have almost no interstellar matter, and very little formation of stars. There are, however, remnants of small dust particles. A lot of aging stars are present in this
The universe is continuously being explored by astronomers and scientists. This exploration and research endeavors have led to the discovery of many other galaxies and celestial phenomena that had been unknown to us for many years. Now, the Milky Way galaxy, which is our galaxy, is now part of a Local Group, where about thirty

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

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 Hubble Space Telescope (HST) is considered to be the greatest space equipment ever to have been made. This special telescope gets its name from noted astronomer Edwin Hubble. Funding for the Hubble Telescope came during the 1970’s; however, it was not launched until 1990. It is a space telescope that floats hundreds of miles
