Planetary alignment? Increase in volcanoes?

The book called “The Jupiter Effect” suggested an alignment of planets in 1982 would cause earthly catastrophes, including a great earthquake on California’s San Andreas Fault. There’s another planetary alignment, of sorts, going on now. Will it cause volcanic eruptions? Charts, and info, from Guy Ottewell.

Insights on Jupiter at opposition

Like so much in astronomy, Jupiter’s opposition happens in a way that’s cyclical. And the cycle of oppositions for Jupiter is especially pleasing to the mind.

Watch for Jupiter, Saturn and the moon

Watch for the moon, Jupiter and Saturn around June 7, 2020. The moon is very bright now, so Jupiter and Saturn are specks in its glare. Jupiter is a brighter speck than Saturn.

The difference between ‘signs’ and constellations

When – astrologically – the sun enters the “sign” of Gemini, it is still nearly one month away from entering the constellation Gemini in the sky. Astronomer Guy Ottewell illustrates and discusses this difference.

The planets Jupiter and Saturn are exceedingly near each other now on the sky’s dome, heading for a 20-year conjunction later this year. See them with the moon on May 12!
