Watch live from the Greek Orthodox Church of Saint Isidoroi at Lycabettus hill, the Matins/Orthros and the Divine Liturgy. The Saint Isidoroi is a small cavernous Church of the Holy Archdiocese of Athens with daily sacrificial life, where the rock is lost in the Light and becomes a meeting place of the greatest Christian figures of the 4th century, the Cappadocian Fathers Basil the Great and Gregory the Theologian with the young Ascetic, Nectarios of Pentapolis, Porphyrios of Kausokalyvitis and Nikolaos Planas. It is sculpted inside the largest cave of Lycabettus and unites the shadow of the distant capital with the sky. The cave functioned in the 17th century as a hermitage with a small number of monks. The name of the hermitage is due to the finding of the image of Saints Isidore in the hands of a hermit. The Holy Cross dominates the Holy Temple which is located on the west side of Lycabettus Hill in Athens. The channel officially started operating in February 2020 and includes videos from Divine Liturgies, Speeches, Psalms etc.

Comet NEOWISE, officially known as C/2020 F3, provided a unique glimpse into the universe when it made its close approach to Earth in July 2020. Here are some of the revealing changes it brought to our understanding of the cosmos:Ancient Visitor: NEOWISE is a long-period comet, meaning it takes thousands of years to orbit the Sun. Its appearance gave scientists an opportunity to study a relic from the distant past, offering insights into the composition and characteristics of comets from the early solar system.Observation Opportunity: The comet became visible to the naked eye, even in urban areas, which is relatively rare for comets. This allowed millions of people around the world to witness a celestial event and sparked widespread interest in astronomy.Solar System Dynamics: The study of NEOWISE's orbit helped refine our understanding of the dynamics of comets in the solar system, including their trajectories, orbital parameters, and how they interact with the Sun's gravitational pull.Composition Insights: Scientists used spectroscopy to analyze the light emitted by NEOWISE. This analysis revealed valuable information about the comet's composition, such as the presence of dust and various chemical compounds, shedding light on the materials present in these ancient objects.Contribution to Space Science: NEOWISE's observation added to our knowledge of celestial bodies and their behavior in space. It provided data that contributes to the broader field of planetary science and helps us understand the origins and evolution of comets.In summary, Comet NEOWISE's passage by Earth in 2020 allowed scientists and enthusiasts alike to witness a cosmic event and gain new insights into the composition and behavior of comets, contributing to our broader understanding of the universe and its history.
