 If you are interested to use Professional Telescopes(remotely-over the internet), There is another way, you may you one or several telescope for Science, Research, Astro -photography. This telescope would be in  advantage, when you are interested in carrying out independent research etc. But this comes at price/cost. To check the pricing and telescope details refer to below site. https://www.itelescope.net/ Below is translation of above text in Portuguese by Jéssica (Dentist from Brazil, Rio de Janeiro) iTelescópio, telescópio comercial, para pesquisas e usos independentes  Se você está interessado no uso de telescópios profissionais (de uso remoto), há outra maneira, você pode usar um ou vários telescópios para uso científico, pesquisa ou astrofotografia. Esse telescópio é vantajoso se você está interessado em realizar uma pesquisa independente, etc. Mas isso tem um preço. Para verificar os preços e informações sobre o telescópio consulte o site abaixo: https://www.itel...

 Stonehenge is prehistoric Archeoastronomy Site.

The shape of the moon is irregular and looks much like a potato shape. Possibly it is thought to be a remnant of a larger moon that was destroyed by a major impact. Image Credit Source-Nasa. Enjoyed 3D model view of Hyperion by turning the object. Below is translation of above text in Portuguese by Taynna(medical student from Brazil) A forma da lua é irregular e parece a forma de uma batata. Possivelmente pensa-se assim por ser um pedaço remanescente de uma lua maior que foi destruída por um impacto grande.  Créditos da imagem Source-Nasa Aprecie o modelo de visão 3D . Thanks Taynna 😊 

 Betelgeuse Star ( also called Alpha Orion) is the 10th brightest star in the night sky. Looks reddish in color and magnitude varies from +0.0 to +1.6.                                                                  Image credit:NASA Easy to spot - locate Orion constellation and try to locate Reddish color Star. In this image it appears in top left. To see the changes in magnitude over past decade(from 1911 to 2001) refer to below image- image credit and link - https://www.aavso.org/sites/default/files/images/LTbetelgeuse.jpg Below is translation of above text in Portuguese by Elaine (Teacher from Brazil, In São Paulo) Sobre  a Estrela Betelgeuse    A estrela Betelgeuse (também chamada de Alpha Orion) é a décima estrela mais brilhante do céu noturno.  Parece averme...

We all know we see one side of the moon due to its same rotation and revolution period. In general sense far side of the moon is not possible unless there is rover or satellite to take the photos. Lunar libration at its longitude happens happens when Moon's rotation sometimes leads and sometimes lags its orbital position, it can reach to 7°54′ in amplitude.   Lunar libration at its latitude happens because of slight inclination (about 6.7°) between the Moon's axis of rotation and the normal to the plane of its orbit around Earth.   Diurnal libration is a small daily oscillation due to Earth's rotation, which carries an observer first to one side and then to the other side of the straight line joining Earth's and the Moon's centers, allowing the observer to look first around one side of the Moon and then around the other.  Overall this give opportunity to see more surface of a moon at different times. So instead of 50 % we are able to see (over the time) 59% of...
