 IN THE NEWS:

THE JUNO MISSION

Juno the satellite, arrived at Jupiter on 4 July under a great umbrella of Earthly excitement. We shall now be able to learn so much more of the big gaseous giant, to find out what makes it tick!

18 days ago, on 28 August, NASA’s Juno Mission successfully executed its first of 36 orbital flybys of Jupiter, passing 4200kms. above Jupiter at a speed of 208000 kms. per hour.

This mission is estimated to end in February 2018. NASA Southwest Research Institute advises that they have recorded very intriguing data and only as time goes by will scientific results be available for release to the public.

This is one of the best chances for our scientists to study the galactic environment and our Solar System, to find out about our beginnings. Juno has on board many different  and new scientific instruments to do just that. We will lift the mantel and find out what is beneath Jupiter’s gaseous atmosphere. We can find out about other worlds, like our Earth, orbiting other stars as their suns and learn about the evolution and formation of our own Solar  System.

More information on the Juno mission is available at:

Planets in SEPTEMBER:

The planets are in much the same situation as what they were in August.

Mercury, Venus and Jupiter:These three planets sinking fast. They are lower down in the west than they were in August, they and are  gone by mid evening.

Mars and Saturn:  are still brightly visible each night but are now situated high in the sky. Moving westward with Scorpious, together they will all be gone from our sky in the early morning hours. Keep observing them as they travel westward and absorb their beauty for they will have left our skies by November.

 Deep-sky objects:

 

M4 – NGC 6121  ( Scorpious) M4 is the Milky Way’s Largest globular cluster, Omega Centauri, sparkling with ten million stars.

M8 – NGC 6523    (Sagittarius) The Lagoon Nebula

M6 – NGC 6405    (Scorpious) The Butterfly Cluster

M20 – NGC 6514  ( Sagittarius) Trifid Nebula

 Meteor Showers:

Most important: A dark sky, is what is needed to observe meteors.Moonlight is a chaser. A dark sky is important so patch in to see what the moon is doing and schedule your dates and times for meteor sightings.

Meteor, Meteoroid or Meteorite?

Whenever a meteoroid enters the atmosphere of the Earth, it generates a flash of light called a meteor, or “shooting star.” High temperatures caused by friction between the meteoroid and gases in the Earth’s atmosphere heats the meteoroid to the point where it starts glowing. It is this glow that makes the meteoroid visible from the surface of the Earth.

Meteoroids generally glow for a very short period of time – they tend to burn up before hitting the surface of the Earth. If a meteoroid does not disintegrate while passing through Earth’s atmosphere and hits the Earth’s surface, it is known as a Meteorite. Meteorites are thought to originate from the asteroid belt, though some meteorite debris has been identified as belonging to the Moon and Mars.

What is a Meteor Shower?

Sometimes, meteors occur in clusters known as a meteor shower. Meteor showers occur when a comet comes close to the sun and produces debris – meteoroids – that spread around the comet’s orbit. Anytime the Earth’s and the comets orbit coincide, the Earth experiences a meteor shower.

Since meteoroids that create a meteor shower all move on a parallel path, and at the same velocity, they seem to originate from a single point in the sky to observers on Earth. This point is known as the radiant. By convention, meteor showers, especially the regular ones are named after the constellation that the radiant lies in.
