KNOW YOUR NIGHT SKIES : THE WEEK'S NIGHT SKY

OUR SOLAR SYSTEM

Enjoy the night sky each week, as we give you the latest on stargazing. 

SEE WITH THE NAKED EYE 

Visible planets this month in order of disappearance:  Mercury, Jupiter, Saturn, and Mars. If you are lucky to have a flat horizon in the northeast and like planet Venus, you will be seeing it in the morning sky. This month, Mercury will reach its highest point in the evening sky on the 2nd of October and Mars will be at opposition, closest to Earth, on the 14th of October. Thus we will be able to easily see features from Mars in a telescope. 

  • The Sun is in the zodiacal constellation of Virgo. It sets around 07:47PM and rises around 06:24AM.
  • This week, the Moon’s current phase is a waxing crescent, it will become a Full Moon on November 1st.
  • Mercury is in Libra. Is 104 million kilometres from Earth, about 6 light minutes away.
  • Venus is in Leo, visually very close to the Sun. Is at 179 million kilometres from Earth or about 10 light minutes away. 
  • Mars is visually in the zodiacal constellation Pisces, at a distance of 64 million kilometres, or just about 4 light minutes away, visible at night. 
  • Jupiter is in the constellation of Sagittarius at a real distance of 771 million kilometres or about 43 ight minutes from Earth.
  • Saturn is visually in Sagittarius, very close to Jupiter and 1491 million kilometres away or 83 light minutes away.

SEE WITH BINOCULARS AND TELESCOPE

  • Uranus is in Aries. It has a visual magnitude of +5.7 so under a very dark sky and if you have amazingly good eyes you might be able to see it, with the naked eye. It’s at 2813 million kilometres from Earth or about 156 light minutes away approx. 
  • Neptune is in the evening sky, in Aquarius at 4359 million kilometres from Earth. It takes light approximately 4 hours to reach us from Neptune. At a visual magnitude of +7.8 you will need binoculars or telescopes to see it. 
  • Pluto in Sagittarius, very close to Jupiter. We cannot see Pluto with the naked eye, as it has a magnitude of +14.4 is 5117 million kilometres away, at about 284 light minutes – more than 4 hours and 30 light minutes. 

Of course, none of the planets make light of their own, what we see are the features of each planet illuminated by the light from the Sun that gets reflected by our Solar System companions.

After dark adaptation and under the very best observing conditions, the average limiting magnitude of the human eye is about magnitude 6.5. 

IN OCTOBER

The Milky Way’s centre is now on the western horizon after sunset. Scorpius and Sagittarius are the two constellations whose stars are between us and the galactic centre. We are very lucky here in New Zealand to see the centre of the Milky Way high in the sky, which means we are looking at it through less layers of atmosphere than in the Northern Hemisphere. In the Northern Hemisphere, from mid latitudes, the centre of the Milky Way climbs only about 30 degrees above the horizon. 

Check out our resource on how to find Scorpius. We  made this for our light pollution campaign, look after our night sky. 

October is a good month to still see many deep sky objects. The majority of them are around the galactic bulge. In Scorpius, our favourites are: Ptolemy’s cluster – M7 a beautiful open cluster of stars, the Butterfly Cluster – M6, which resembles a butterfly, and the globular clusters Messier 4 and Messier 80. The Bug Nebula NGC 6302 and The Cat’s Paw nebula – NGC 6334 are excellent astrophotography targets. Neighbouring Scorpius is Sagittarius. This is the constellation where we map the centre of our galaxy, the Milky Way. Sagittarius’s famous asterism (grouping of stars) is the teapot, which is visible upside down here in New Zealand. Sagittarius cannot be seen from Scotland or Scandinavia. We are very lucky here to be able to observe it overhead.

The Milky Way is at its densest in Sagittarius.  Inside the constellation, which is a patch of the sky, we can admire two beautiful Star Clouds, easily seen in binoculars: the Large Sagittarius Star Cloud and the Small Sagittarius Star Cloud – Messier 24. Some stunning deep sky objects in Sagittarius are Lagoon Nebula – M8, Omega Nebula or Swan Nebula and the Trifid Nebula, another famous one also known as M20. The Trifid Nebula is about 2 degrees from Lagoon Nebula.

In the circumpolar region, the Small Magellanic Cloud is in a good position to observe. Close to it, 47 Tucanae is one of the most beautiful and large globular clusters that adorn the night sky. 47 Tucanae is the second brightest globular cluster in the sky and one of the most massive clusters in the Galaxy. It’s angular diameter is roughly the size of the full Moon, that is the width of your pinky at arm’s length. It can be seen with the naked eye from Earth although it is far far away, about 13,000 light years from Earth. 

The three famous crosses of the southern sky, the Southern Cross, Diamond Cross and the false cross are very low on the horizon, and for the next three months we will be looking at them through an extra layer of atmosphere. 

Some notable deep sky objects this month are Helix Nebula in Aquarius, Dumbbell Nebula in Vulpecula and the Grus Quartet in Grus. Famous for its nickname “The Eye of Sauron” Helix Nebula is a very large planetary nebula. Dumbbell Nebula – M27 in Vulpecula is very bright and the first planetary nebula to be discovered. In Grus, a gathering of four interacting galaxies are known as the Grus Quartet. They are fascinating to see in a large telescope. 

Bright Objects

Beautiful bright stars are visible in the night sky. Right at the top of the sky, Antares, the red giant and main star from Scorpius shimmers in an incredibly beautiful red colour as seen through a telescope. On the southern horizon lays Canopus, glistening all colours, including red and green as we see it through the atmosphere. On the opposite side, on the northern horizon is Altair, the main star in Aquila.

Just after sunset, at the beginning of the month, you can catch a good view of planet Mercury, which now reaches its highest point in the sky and sets about two hours after the Sun. Jupiter and Saturn are evening objects, they are visible at Zenith. Mars is visible after 9 PM and Venus is just slightly visible in the morning, rising one hour before the Sun. 

ASTRONOMY ON TAP

If you wish to attend a detailed presentation about the night sky, come every first Tuesday of the month to Astronomy on Tap. During these evenings we extend our live sky presentation and go deeper into space. This is a great opportunity to share thoughts and findings with other people interested in space over a refreshments and nibbles.

RESOURCES

There are beautiful objects you can see in the night sky, some are circumpolar and some are seasonal.

  • An in-depth look at the area between the Southern Cross and the Magellanic Clouds here.
  • Binocular Objects between Southern Cross and the Diamond Cross here.
  • If you wish to see how would it be to fly through Matariki watch this video.

From Wellington it is always a great time to learn the main asterisms (groupings of stars) that make the main constellations since our light pollution does allow us to observe only the brightest stars.

You can also observe craters on the Moon – here is a comprehensive map of it by Google Moon. 

THE MOON

On average, the Moon rises or, if it’s already in the sky, sets about 50 minutes later than the previous day, every day.

New Moon: Sunday, November 15th 06:07:25PM

First Quarter: Saturday, October 24th 02:23:12AM

Full Moon: Sunday, November 1st 03:48:57AM

Last Quarter: Monday, November 9th, 02:46:17AM
