With this list, we present a few nebulae of various types that are said to resemble birds, and while some of the structures mentioned do actually resemble some of our feathered friends, others do so […]
Nebulae are large clouds of interstellar dust and ionized gases which provide the basic building blocks from which the stars and solar systems are created. These stellar nurseries are mostly composed of hydrogen (90%) and […]
Nebulae of all types are among the most spectacular and spookiest looking structures in the entire Universe, and have been an endless source of intrigue and discovery for astronomers. How we perceive them, however, is […]
In a previous post we mentioned that nebulae of all types are among the most spectacular, scary, complex, and sometimes least understood objects in the entire Universe, and how we perceive them often depends on […]
Nebulae are among the most beautiful, complex, and least understood objects in the entire Universe, with how we perceive them often depending upon our skill in manipulating photographic images, rather than our observation skills. In […]
The purpose of this list is to show that you do not always need a telescope to observe literally thousands of spectacular deep sky objects (DSOs) in the night sky. In most cases, the objects […]
While each successive generation of telescopes has revealed more of the Universe than we could have imagined existed, it seems somewhat strange that the exact origin of the optical telescope is in doubt. What is […]
Our Sun is often described as an “average yellow dwarf star”, but the truth of the matter is that there are no average stars. Stellar bodies come in a bewildering variety of masses, luminosities, radii, […]
Pluto (134340 Pluto) was the first Kuiper Belt object to be discovered in 1930, and is the biggest, and second-most massive dwarf planet known to exist in the solar system. It is also the ninth […]
Saturn has been observed since prehistoric times, with the planet having played a major role in all major ancient cultures and religions throughout history. The ancient Babylonians, for instance, kept records describing detailed observations of […]
