ASTRO LOG: APRIL 2019 SKY EVENTS TO LOOK FORWARD TO

The change of seasons ushered in days of gloomy weather; let’s hope this won’t drag on until April!

There’s a meteor shower (Lyrid meteor shower) to watch out for in the middle of the month, but because of the presence of the Moon at the night sky, spotting the Lyrids will be pretty tough for avid sky watchers and observers.

Planets such as Venus, Mars, Jupiter, and Saturn will be still be spotted near the Moon in the coming days, and many brilliant prominent winter constellations and deep-sky objects will be seen during early evening hours.

Sky treats such as the nebulae in Orion constellation (Great Orion, Flame, and Horsehead), and galaxies like the ones in and the Leo Triplet and Sunflower Galaxy still await amateur astronomers and astrophotographers. read more

ASTRO LOG: Your February Sky Treats

February opens with the gradual exit of the Moon from the night sky, which means observers will start the second month with a trove of prominent bright winter constellations such as Orion, Taurus, Auriga and Gemini and spring constellations like Ursa Major, Leo and Virgo after midnight.

Several deep-sky objects such as the Orion Nebula, Flame and Horsehead Nebula, Crab Nebula, Messier 53 and Pinwheel Galaxy can also be observed under relatively clear, moonless and dark skies.

Planets Mars and Uranus are going to be a regular sight right after sunset, while the bright planets Venus, Jupiter, and Saturn will be gracing the night sky in the early morning hours until sunrise.

Meanwhile, there will be barely or no sighting at all of planets Mercury and Neptune because of their nearness to the Sun as seen in the sky.

Days are still long, with late sunrises from 6:46 to 7:04 in the morning and early sunsets from 6:04 P.M. to 6:24 in the evening.

For more serious sky watching,Al Sadeem Astronomy has prepared below a calendar for February’s sky events.All dates and times were given in UAE Local Time (UTC+4).

ASTRO LOG: What to Watch Out for This January 2019

As the United Arab Emirates’ (UAE) coldest month ushers in, a number of well-known winter constellations and deep-sky objects will spruce up the January sky.

The Orion nebula, Perseus cluster, Andromeda galaxy, and the brilliant open star cluster of Pleiades known as the “Seven Sisters” in Taurus (The Bull), will be more prominent in the winter sky, and can be seen as early as 7:30 P.M.

Notable star patterns, or astronomical asterisms, like the Winter Triangle and Winter Hexagon, will also adorn January winter nights.

Planets Mars and Uranus, meanwhile,will be visible after sunset until an hour before midnight. The brighter planets Venus and Jupiter can be observed at 4:30 in the morning until sunrise.

For Mercury fans (not the singer), as well as those of Saturn and Neptune, January will not be a favorable month to observe these planets because of their significant nearness to the Sun.

Expect even shorter days in January with late sunrises from 7:04 to 7:06 in the morning and early sunsets from 5:45 P.M. to 6:07 in the evening.

Comet 46P/Wirtanen Graces the December Night Sky

Before 2018 comes to a close, the last comet of the year will make its nearest approach to Earth.

Comet 46P/Wirtanen, one of the three comets discovered in 1948 by American astronomer Carl Wirtanen, will be as bright as a third (3rd) or fourth (4th) magnitude star—which means it will be visible enough to be seen with the naked eye, especially in completely dark skies. read more
