Meteor shower from Tau Herculids – exact time “all or nothing” event peaks and how to watch them – World News

A NASA chief has warned that the Tau Herculids will be an “all-or-nothing event,” with their visibility here on Earth dependent on the speed at which space rocks separate from a mysterious comet

The Tau Herculids are a little different from other meteor showers.

While we usually know what to expect from regular space events – hundreds of years of observing and noting will have that effect – some are a little harder to predict because of events in space.

The Tau Herculids certainly fall into that category, and while thousands of meteors could shoot across the sky every hour, there’s also a good chance nothing at all will happen.

Unfortunately for the British, the Tau Herculids will mostly be visible to stargazers in North America.

But even for people who are in the right place at the right time, there’s a good chance they won’t be able to see anything at all – making this particular meteor event “all or nothing.”

The Tau Herculids are scheduled to take place on the night of May 30th to May 31st.

They are expected on Tuesday, May 31 from 4:45am to 5:17am GMT or 12:45am to 1:17am EDT.

If things really take off and the possibility of 1,000 meteors per hour comes true, then the Tau Herculids would not be a meteor shower, but more like a meteor storm.

Why is the Tau Herculids an all or nothing event?

Tau Herculids are an all-or-nothing event as their visibility depends on the speed at which they were left behind by their comet.

Meteor showers are often caused by the Earth flying through a debris tail left by a comet orbiting the Sun.

April’s Lyrids meteor shower is a good example of this, as Earth plows through the tail of comet C/1861 G1.

Although officially discovered in 1861, human history of seeing the Lyrid Show is believed to date back around 2,700 years.

Like the Lyrids, the Tau Herculids follow the debris of a comet, this time 73P/Schwassmann-Wachmann or SW3.

It was discovered in 1930, but by 1995 scientists believed it had fragmented because it had brightened significantly.

Earth’s next near pass came in 2006, when astronomers discovered more than 70 pieces of the once-uniform rock.

And they found that it was still dissolving. This continued fragmentation is why astronomers cannot say for sure whether the night of May 30 will be studded with meteors or just another night.

Bill Cooke, head of NASA’s Meteoroid Environment Office at the Marshall Space Flight Center in Huntsville, Alabama, said, “This is going to be an all-or-nothing event. If SW3’s debris was traveling at more than 220 miles per hour as it separated from the comet, we could see a beautiful meteor shower.

“If the debris had slower ejection speeds then nothing will reach Earth and there will be no meteors from this comet.”
