A DOUBLE meteor shower will peak tonight as two celestial events overlap


A DOUBLE meteor shower will peak tonight as two celestial events overlap to bring up to 30 shooting stars per hour

  • The Alpha Capricornids and Southern Delta Aquariids are now in full swing 
  • Alpha Capricornids peaked on 27th, and the Southern Delta Aquariids on 30th 
  • Both will produce visible shooting stars, made more clear by a dark moon

The overlap of two peaking meteor showers this week could light up tonight’s sky with dozens of shooting stars.

Both the alpha Capricornids and the Southern delta Aquariids reach maximum activity toward the end of July – and, with the new moon nearing, extra dark skies could make for prime viewing.

The alpha Capricornids peaked this weekend and will continue to produce visible meteors through the beginning of next month, while the Aquariids will peak Monday night into Tuesday.

Both the alpha Capricornids and the Southern delta Aquariids reach maximum activity toward the end of July. The Southern delta Aquariids will peak on 30th, with 10-30 shooting stars per hour

According to the American Meteor Society, the Southern delta Aquariids have been active since July 21 and will reach maximum activity on the 30th.

These meteors tend to be relatively faint, AMS says, though there may be as many as 10 to 30 visible in the sky per hour.

Where you live will determine how many you’ll be able to see.

‘For observers in mid-northern latitudes, the radiant lies low in the south and hourly rates will lie closer to 10,’ according to the AMS.

‘The radiant is best placed in the southern tropics where it passes overhead and rates there will be closer to 30 at maximum.’

The alpha Capricornids, on the other hand, went into swing earlier in the month and reached their peak on July 27.

They’re expected to continue at a dwindling rate through August 11, and may bring three to four per hour.

Viewers in mid-northern latitudes will have the best chance of seeing one of these fireballs.

The alpha Capricornids will now be much more visible than they were earlier in the month, when they had to compete with light from the bright full moon.

As the alpha Capricornids come to an end, the Perseids will begin to start popping up.

But, a full moon could steal much of the show.

The Perseids peak on August 13 and typically bring as many as 100 shooting stars per hour. With the peak being two days before the full moon, though, visibility won’t be ideal.

‘Under such circumstances Perseid rates will usually be reduced by at least 75%,’ according to the AMS.

‘These rates are still better than most nights of the year. So if your sky is clear and transparent it would not be a waste to try and view this activity.

‘Just be certain that you view in the opposite direction of the moon so that you can see the faintest possible meteors.’

WHAT ARE THE DIFFERENT TYPES OF SPACE ROCKS?

An asteroid is a large chunk of rock left over from collisions or the early solar system. Most are located between Mars and Jupiter in the Main Belt.

A comet is a rock covered in ice, methane and other compounds. Their orbits take them much further out of the solar system.

A meteor is what astronomers call a flash of light in the atmosphere when debris burns up.

This debris itself is known as a meteoroid. Most are so small they are vapourised in the atmosphere.

If any of this meteoroid makes it to Earth, it is called a meteorite.

Meteors, meteoroids and meteorites normally originate from asteroids and comets.

For example, if Earth passes through the tail of a comet, much of the debris burns up in the atmosphere, forming a meteor shower.
