 Highlights

From a very dark location at that time, look for the Zodiacal Light, a huge soft glowing column of light in the western horizon. It is the light of the Sun reflected off dust particles in the inner solar system. Its axis closely coincides with the ecliptic.

The Lyrids
On April 21 (16-25) The Lyrid meteor shower reaches maximum; The peak is broad so that the number of meteors should be consistent until morning twilight. Although the Lyrids are considered a major shower, they produce a meteor only every 3 to 5 minutes, on average. The near New Moon will compete with the shower. The Lyrids are named after the constellation of Lyra from which they seem to radiate. deep-sky objects to have been recorded by the ancients, being mentioned by Aristotle around 325 BC.

The Summer Triangle
The morning sky, before dawn, now provides a preview of summer evenings. The Summer Triangle -- Vega, Deneb, and Altair -- holds the central position, high in the south. The scorpion sits low to the south and slightly west. Directly to the arachnid's east is Sagittarius, the Archer, and between the two lies the direction toward the Milky Way galaxy's centre. The ribbon of soft light that delineates our galaxy flows up from the south, through the Triangle, and then cascades toward the northern horizon.

Saturns slow progress against the starry background means that it will be well-placed for observing though early summer this year. By mid-evenings in April, the planet is more than halfway up the sky in the southeast and by late evening, the Ringed Planet is at its highest in the south.
Saturn is plainly visible as an extra star in the constellation of Leo the lion. The planet is just east of the bright star Regulus, the star that symbolises the lions heart. Regulus is also considered to be the dot of the backward question mark of stars that forms Leos head and mane. Watch for the moon near Saturn on April 14 and 15.

There is a major meteor shower next month, the Lyrids, peaking on the evening of April 21. Unfortunately, an almost-full moon will shine in the sky all night, making viewing conditions less than ideal for seeing many meteors.

Mercury and Venus are both very close to the Sun, so they are more or less out of sight this month. Mars is high up in the western sky at dusk, and Jupiter is now playing the role of Morning Star: it rises in the east about three hours before sunrise. Saturn on the other hand is high in the east at dusk, and doesnt set until shortly before sunrise. On 13 April dont miss to spectacle of Saturn (in Leo) and Mars (in Gemini) with a crescent Moon suspended between the two. After a break of a few months, the meteors are back again. The Lyrid shower is active during the third week of April, and will peak in the early hours of 22 April, producing one meteor every 10 minutes or so.
