M57 (The Ring Nebula) is a planetary nebula located in the Lyra constellation at a distance of 2,300 light years from the earth. The shell of gas was produced by a red giant that has to evolve away. The expansion rate of this nebula indicates that it is 10,000 years old. Make sure you are […]

The International Space Station (ISS) is a space laboratory where astronauts stay for a period of time and do experiments. It moves around the Earth at around 300 miles up and at 17,000 mph. It has several parts like the solar array wings working as power stations, rooms and laboratories for the astronauts, and all […]
Comets are a mixture of ice, frozen gasses, dust, and rocks. Scientists think that comets are the debris from materials that formed the solar system initially around 4.6 billion years ago. Comets follow elliptical orbits around the sun. The more it gets closer to the sun, the faster it is pulled in. Some comets fall […]
Telescope has revealed the interesting fact that all stars are not alone. Sometimes they are accompanied by one or other multiple stars and form star systems. Double stars that are bound gravitationally are called binary star systems. According to the research around 85% of the stars of the Milky Way are in binary pairs unlike […]
The Orion Nebula, also familiar as M 42 is easy to spot and visible to unaided eyes. It is one of the brightest Nebula in the night sky with a magnitude of 4. It is located in the Orion constellation and includes stars, ionized gas, and dust. This diffuse nebula extends across a 1° region […]
The Andromeda galaxy is the nearest galaxy to the Milky Way located at 7.7° northwest of Mirach. This is the only galaxy you can see with bare eyes without any optical aid. However, it appears as a faint misty patch on a moonless night at a short distance from the band of the Milky Way. […]
The Milky Way is a common spiral galaxy with a visible diameter of 100-200 thousand light years. It has 4 main spiral arms having 100-400 billion stars in each of them and our solar system is located in Orion’s arm. You can see the other side of the Milky Way even with unaided eyes. From […]
A galaxy is referred to as the collection of dust, gas, hundreds of billions of stars, and their planets which are held together by gravity. A galaxy is the most distant object you can see with your telescope. They appear with different shapes and colors and we can see the combined glare of all the […]
A nebula is a cloud of gas and dust composed of Helium, Hydrogen, and other ionized gasses. They become visible from Earth due to the interaction of gas with other materials or supernova explosions. However, it is possible to see a nebula with a telescope. Typically a nebula looks gray though the view improves with […]
Photo: The Dogstar (Sirius A) and its Pup (Sirius B) Sirius, also known as the Dog star, is the brightest star in the sky found in late winter and spring. It has a tiny companion named Sirius B known as Pup which is basically a white dwarf star. Both of them make a binary star […]
