AstonomyAlso known as the first science, and an ultimate curiosity of the humans since space is the least we know about. In this section learn more about the history of astronomy, astronomy as a science, latest news of our universe, and updates on our space projects.
TelescopesIf you are interested in astronomy and want to scratch that curiosity itch,there is one essential tool you will need to be able to observe the skies, which is a telescope. Here you can find out about the different types of telescopes, their capabilities, and how to use them.
AstrophotographyAlright, so you are into the science of astronomy, maybe as a hobby or maybe as a professional scientist. You have your own telescope and observe the skies. An important part of it is to be able to capture what have seen, or maybe discovered. Here is where you will know how to do just that.
The ancient Greeks inherited astronomical records from the Babylonians and used the information not just used for practical goals but also to construct a cosmological framework incorporating philosophical ideas. Thales of Miletus (620 B.C.E. – 546 B.C.E.) Thales, known as “father of philosophy”, was much involved in the problems of astronomy and provided a number […]
The earliest written records (i.e. history) were astronomical observations – Babylonians (~1600 B.C.) recorded position of planets, times of eclipses, etc. – also evidence from early Chinese, Central American and North European cultures such as Stonehenge, which developed a system for calculating the position of planets and the Sun. Probably the most famous ancient […]
No it wasn’t broken… but it would be nice to be able to see it for more than a few seconds… Imagine this conversation: “Oh wow, man, you have to see this. I found a red star right next to a blue one!” “Oh let me see! Let me see! … I don’t see anything!” […]
There are two popular types of catadioptric telescopes: the Schmidt-Cassegrain and the Maksutov-Cassegrain. The Maksutov-Cassegrain telescope design has essentially the same advantages and disadvantages as the Schmidt. It has a thick meniscus-correcting lens with a strong curvature and a secondary mirror that is usually an aluminized spot on the corrector. The Maksutov secondary mirror is […]
Refractor telescopes are telescopes that use lenses to gather and focus light. Refractors deliver sharp, high-contrast images with crisp views of the moon, planets and stars. Refractors are known for their rugged simplicity. They are easy to aim, they need little maintenance and lenses rarely need alignment-very popular for beginning students of astronomy. Reflectors are […]
In its simplest terms, an optical telescope is one that is designed to collect light in the visible spectrum. In other words, light that can be seen with the eyes rather than through using specialized equipment. This is done through the use of lenses and mirrors which collect the light and create an enhanced image […]
Very hot or more energetic objects in space can emit x-rays and the hottest or most energetic objects in space give off gamma-rays, the most energetic waves we know. X-rays and gamma rays from space, however, cannot penetrate the Earth’s atmosphere, because the short wavelengths get disrupted and weaken in the atmosphere. Scientists like to […]
Objects that are cooler than stars don’t give off visible light, but they often give off infra-red waves (sometimes called heat waves). One of the biggest problems with trying to detect faint infra-red waves from space is that everything on Earth (including everything around the astronomer, and the astronomer himself for that matter) is giving […]
There are objects and processes in the universe that put out natural radio waves. Radio telescopes look at very long wavelength light, the radio frequency portion of the electromagnetic spectrum. To gather radio waves from space, astronomers use giant metal antennas otherwise known as radio dishes (as most resemble a soup bowl of some sort). […]
A telescope is an instrument for collecting radiations or light from the distant objects in space. Telescopes have been one of the most awe-inspiring instruments to not only the ardent scientists and astronomers, but to almost every human being. To be able to view fascinating objects billions and billions of miles away from us is truly […]
There are two distinct methods for capturing or creating planetary images. When I say capture I am referring to the traditional method of photographing an image. Originally we used photographic film which is covered in light sensitive crystals (silver halide) that vary in size depending on the film’s speed. The slowest films, ISO 100 or […]
There is a lot to be said about stellar night photography, but let’s start with the basics. Presumably you are equipped with a Digital Single Lens Reflex. The reason for selecting a DSLR camera is that what you see through the viewfinder is shared with the imaging sensor. What You See Is What You Get […]
