Scorpius, the celestial scorpion, is a fascinating constellation!

“Scorpius’ eye,” which could relate to the bright star Antares in the Scorpius constellation. Antares is often called the “heart of the scorpion” due to its reddish hue and prominent position -it’s a red supergiant star and one of the brightest in the night sky.

Spica is not a single star, but a binary system, meaning two stars orbit closely around one another, every four days. The stars lie approximately 11 million miles (less than 18 million kilometres) away from each other and appear as a single point of light in the sky.

Eta Aquarids (5th thru 6th May)

  • Beginning to ending date: 19th April to 28th May
  • Peak Date: 5th thru 6th May
  • Rating: Strong
  • Zenith Hourly Rate (ZHR): around 50 per hour
  • Radiant Position: RA: 22h 20m / DEC: -01°
  • Degrees: 45º  (Face:- NorthEast)
  • Comet: Comet 1P/Halley
  • Note: poorly seen from the UK.

Note: the radiant of the Eta Aquarids, which peaks around 5th thru 6th May, is challenging to observe from the UK due to its radiant in the constellation Aquarius being quite low on the horizon during dawn in the UK – the low altitude means that fewer meteors are visible because the Earth’s atmosphere obscures part of the view.

To locate castor in Gemini using the Moon as a guide, here’s a simple star-hopping method

  1. Find the Moon
    Start by identifying the Moon in the night sky. Its position changes nightly, so check its location relative to Gemini.
    o
  2. Locate Gemini
    Look for the two bright stars, Castor and Pollux, which represent the heads of the Gemini twins. They are close together and form a noticeable pair.
    o
  3. Star-Hop from the Moon
    If the Moon is near Gemini, use it as a reference point – move your gaze towards the brighter of the two stars—Pollux—and then to Castor, which is slightly dimmer and to the right of Pollux.

oooo
Castor is a fascinating star system, as it’s actually a three binary stars, meaning it consists of six stars bound together by gravity!
