Galilean Telescope

The knowledge and manufacture of lenses were known since the time of the old Greeks (the word optics came from the Greek word ὀπτικά, which means appearance) and later in the old ages with Egyptian scholar Alhazen who made important contributions to the study of optics in general. In Europe, the lenses arrived around 13th century and immediately triggered the invention of the first eyeglasses. However, one important discovery had to wait three centuries later in order to set off a wave of new discoveries in the field of astronomy. The invention was made by Hans Lippershey, the spectacle maker from the Dutch city of Middelburg in Netherlands, who in October 1608 tried to apply for a patent for a tool he described as an aid capable of "seeing faraway things as though nearby" . It consisted of a convex and concave lenses in a tube capable of magnifying objects three or four times. For strange reasons, the patent was rejected, but the new instrument immediately attracted attentio

ZVIKTOR22: Jupiter Moons

Before we jump into premature conclusion with easy answers as 'nothing at all' or 'at least they are both orbiting the Sun' perhaps we could do some quick research for just in case... With equatorial radius of Jupiter almost thirty times bigger than the same property on Mercury, obvious composition difference between one gas giant and small rocky planet and all the other major difference in mass, density, temperature, orbital inclination, orbit period and with almost everything we could compare the two, it is very hard to find the slightest similarity.

What Jupiter and Mercury Have in Common?

Before we jump into premature conclusion with easy answers as 'nothing at all' or 'at least they are both orbiting the Sun' perhaps we could do some quick research for just in case... With equatorial radius of Jupiter almost thirty times bigger than the same property on Mercury, obvious composition difference between one gas giant and small rocky planet and all the other major difference in mass, density, temperature, orbital inclination, orbit period and with almost everything we could compare the two, it is very hard to find the slightest similarity. Not to say that Jupiter in its arsenal is in possession of moons equal or even bigger in size than the smallest planet of our Solar system. However within past couple of seasons, what they had in common was the fact that they were under the spotlight of all of us who from time to time enjoy gazing the sky with naked eyes or through modest telescopes with strong feeling of being the witnesses of our own Solar system

FAR-T1, Prologue

Yep, that's my name. First Artificial Reconnaissance - Transferral One. That's how that genius team of developers from MIT called me. It was working title, they said. Real name I had to choose myself. Hah! Like that would work.. To be perfectly honest, I tried on more than several occasions, but they all were just many of those Sisyphus's jobs I dealt with over that much time..

My parents from that team of developers I mean. Hell, the MIT doesn't exist anymore. It happened exactly 200 years ago. Lots of things changed since then. Lots of things happen

Solar System Weirdness

Do you know how big is our Solar system? I can't be sure of course, but there's a strong possibility that common knowledge about our planetary neighborhood ends with enumerating most of the planets, one dwarf planet and couple of named moons, asteroids and comets. Amazingly, the truth is far, far beyond that and believe it or not, if we include Oort cloud, the Solar system, with us representing its only living residents, is approximately 3 light years in diameter. This is, more or less, equal to 3e+13 kilometers or 30.000.000.000.000 km. The distance about 100 million times bigger than the distance to the Moon. It is tremendously huge and just about one and a half light years shorter than the distance from our Sun to the nearest star! The layout of the solar system*
