The Sky This Month - July 2019

The Glow of Billions

Travel out of the city on a clear moonless night, leaving the dome of light pollution behind you. Stepping out of your car, you are instantly greeted by thousands of stars. This is the true sky that many people never have the chance to see and enjoy from city limits. The night sky is a thing of beauty to grasp. no matter what season – even winter. It is however summer and early fall that we see an extra bonus high above.

The great band of light stretching from the constellations of Sagittarius in the south to the famous “W” of Cassiopeia in the north east is our Milky Way Galaxy. Galactic centre is located off the right side of Sagittarius is about 26,000 light years and thus the heaviest concentration of distant suns. The “ghostly” veil is the collective glow of billions of distant stars that cannot be resolved with th3 f. This is a sight everyone should do at least once in their lifetime. 

And when you do decide to take that road trip, be sure to bring binoculars if you own them. There is a wealth of celestial objects that come into view with simple 8X50 binoculars. As you sweep across the Milky Way with the binoculars, hundreds of stars fills the field of view. 

Two planets are located on either side of Sagittarius with bright Jupiter on the right and Saturn on the left but shining only about half as bright. Saturn is at opposition on the 9th and rises at sunset. You will require larger magnification to catch Jupiter’s moon and a telescope to marvel Saturn’s rings. Almost half way between the planets is a hazy patch of light. This is Messier 8 or simply M8. Otherwise known as the Lagoon Nebula, this “stellar nursery” is slowly forming new stars through the process of collapsing and condensing interstellar gas and dust. Who knows how many new exoplanets might form from these future stars. 

The Lagoon is located 4,100 light years away. Along with its dusty nebulous regions we see tiny inky black Bok globules (named after Bart Bok), which are pockets of dense gas that could form new stars. Located in the nebula is NGC 6530, a cluster of very bright suns. At an estimated age of only 2.3 million years, these juvenile suns are young on the cosmic scale. A bit north and west of M8 (one and a third degrees) is M20. The Trifid Nebula located 5,200 light years away is also a star forming area. It is however more than that. The Trifid contains an open cluster, blue reflection nebula and dark nebula, dividing the target into three segments.

There are two eclipses in July that we will not see from Canada. First is a total solar eclipse on July 2 which mostly crosses the Pacific Ocean west of South America but does make landfall over Chile and Argentina. Then on the night of July 16 is a partial lunar eclipse visible over most of Africa. This month’s full Buck Moon occurs on the 21st. 

July 20 will be the 50th anniversary of humans landing on the surface of the moon. The last half century has seen tremendous advancement in technology and space exploration. We have sent Voyager 1 & 2 to give us a close up look in the gas giants, sent an array of orbiting satellites and rovers to Mars. For almost 30 years the Hubble Space Telescope has imaged the far depths of the Universe. Gravity waves have been detected over the past few years stemming from Einstein’s prediction in 1916. And finally imaging a black hole located 55 million light years away. This is a wonderful age to follow amazing discoveries and enjoy the night sky with today’s state of the art telescopes and cameras. 

Until next month, clear skies everyone.

The Sky This Month - May 2019

Eta Aquarid Meteor Shower

The month of May month begins with the May 4 new moon and will provide dark sky conditions to enjoy the annual Eta Aquarid meteor shower. The entire shower takes place from April 19 to May 28 with the peak occurring on the morning of May 5. The parent comet 1P/Halley which also produces the Orionid meteor shower in October will produce about 40 meteors per hour and vapourize in the atmosphere at 67 km/sec.

While watching meteors dart across the sky, you can welcome Scorpius as it rises before midnight local time in the south. Seeing the familiar arc of three stars along with the red star Antares is a sure sign warmer nights are ahead. Antares is a massive red giant star located 550 light-years (ly) from us. It is about 700 times the diameter of the sun and would fit in the orbit of Mars.

A great project for astrophotographers is the Rho Ophiuchi cloud complex which includes Antares. With simple binoculars, look for the globular cluster M4 located 1.3 degrees west of Antares. M4 is an estimated 7,200 ly away, about 75 ly in width and glows at magnitude 5.6.

Wedged between Scorpius and Sagittarius is brilliant Jupiter. Rising early each week, Jupiter will attain opposition on June 10 thus being closest to earth. A telescope will help reveal its nightly orbit changes of its four Galilean moons. Refer to page 233 of the 2019 RASC Observer’s Handbook for a complete ephemeris of moon transits and accompanying shadow across the Jovian surface.

By 5 a.m. local time, the familiar asterism of the “teapot” is well above the horizon by 3 a.m. with the entire Milky Way painted across the sky to the constellation Cassiopeia. This is Sagittarius and positioned to its left is Saturn. A few degrees above the spout of the teapot is the Lagoon Nebula – M8. This emission nebula commonly called a stellar nursery is slowly forming new stars M8 is seen naked eye on a clear moonless night in the countryside and measures a couple of full moons in width.

On the night of May 10, the 39% lit moon will pass in front of the Beehive cluster – M44. The moon’s motion causes it to move a lunar width in one hour. Starting around 10 p.m. eastern, follow the moon with a telescope as it hides the brighter members of the cluster.

Until next month, clear skies everyone.

The Sky This Month - April 2019

Corvus The Crow

Follow the handle of the Big Dipper as it arcs or bends to the star Arcturus in the constellation Bootes. Continue this imaginary curve to the first magnitude star Spica – alpha Virgo. At 250 light-years (ly) away, Spica shines 1,900 times more luminous than the Sun. It actually consists of two extremely hot B1 and B4 stars that are separated by a mere 0.12 astronomical units or 18 million kilometres.

To the lower right of Spica is a trapezoid of stars, this is Corvus. Mythology states the god Apollo sent the crow with a cup (Crater) in search of water. The crow was distracted by a fig tree, which caused its delay to Apollo. On its return, Corvus gave the excuse a water snake (Hydra) prevented the bird from filling the cup. Apollo did not believe this story and cast all three into the night sky forever.

From the top left of the asterism, we see the star called Algorab located 87 ly away. Moving clockwise is Gienah. This is a hot B8 star some 154 ly away and measures four times the diameter of the Sun. Next, we have the orange coloured Minkar. It is the farthest of the four at 318 ly away and has ballooned in size to measure two-thirds the orbit of Mercury. And last is the G5 star Kraz. It resides 146 ly away and research shows it was a blue-white B7 star only 300 million years ago.

Corvus has a few targets well worth observing and imaging. First, of we have M104 aka the Sombrero Galaxy. This is a lovely lenticular galaxy, almost oriented edge-on and has a very distinct dust lane. The Sombrero is located 31 million ly from us and estimated to be 50 thousand ly in width. Halfway between Corvus and Crater is an unusual spiral catalogued NGC 4027. At 77 million ly away this 11th magnitude galaxy has only one spiral arm.

A classic example of two interacting galaxies is NGC 4038 and 4039 known as the Antennae Galaxies. They are about 80 million ly away and shows the fate of the Milky Way when it collides with the Andromeda galaxy in about four billion years from now. It will be known as Milkomeda.

Speaking about our galaxy the constellation Scorpius with the orange star Antares is above the horizon along with Jupiter by 2 a.m. local time. By 4 a.m. Sagittarius and Saturn can be seen along with the glow of billions of star of the Milky Way. Follow it up and east as it connects the Cygnus the Swan aka the “Northern Cross”, a sure sign days and nights will soon get warmer.

Mars can be seen now passing the Pleiades and will be closest to the star Aldebaran – the eye of the bull in Taurus on April 9.The annual Lyrid meteor shower peaks on the night of April 23 with an hourly rate of 18 meteors per hour.

The full Pink Moon occurs on April 19 which will definitely interfere with viewing the Lyrids.

Until next month, clear skies everyone.
