A composite image showing the Full Moons in 2020 and 2021 by month. Credit: Soumyadeep Mukherjee. The Full Moon phenomenon arises when our planet, Earth, is precisely sandwiched between the Sun and the Moon. This alignment ensures that the entire side of the Moon facing us shines in the sunlight.

The Corona Borealis is located near the constellation Hercules. The position of T CrB is marked with a green dot. This view shows the sky around 2 a.m. local daylight time in mid-April. Please note that the constellations will rise and set at different times throughout the year, but their positions relative to each other
The Sun can send out eruptions of energetic particles. Credit: NASA/SDO via AP NASA has set its eyes on the Moon with the aim of send astronauts back to the lunar surface by 2026 and establishing a long-term presence there by the 2030s. But the Moon isn't exactly a habitable place for people. Cosmic rays

Ancient archaeological sites (such as Stonehenge) were built so that the Sun would shine through a certain opening on some special day (usually a solstice). Wouldn't the precession of the Earth change the geometry of the situation over the years? Michael C. WestBethesda, Maryland If you are
Celestron's next-generation StarSense Autoguider (SSAG) can be mounted on many brands of telescopes. A compatibility list is available on the Celestron website.

The hardware requirements alone can
