Starship Asterisk*

Is this because they are electrically polarised and one consists of electrons and negatively charged ions and is more easily disrupted and the other is positive ions and so less easily disrupted?

Last I looked at this, it wasn't possible to create a complete color image with this quality, so I should have realized this sooner! Here are the details on the Hubble Heritage site:

I just have to send Bo an email now...

Actual image. Do note that some weirdness with the colors is occurring because the cyan channel and the orange channel do not match up entirely due to the very fast movement of the jet. The two datasets used to create the color composite were not captured at the same time. Usually, this doesn't matter, but these jets are moving really fast. Also keep in mind this is not an RGB image.

Actual image .. but not an actual photograph.
"Constructed from Hubble Space Telescope image data, the stunning scene ..." As you said Geck, constructed from two sets of data.

I have enjoyed the idea of today's APOD but what is in its guts may essentially be indigestible. Relativistic jet material starts on page 44 though I suspect it's all pretty relevant. I hope.

My Reader's Digest version is: The words are too small and there's way too many of them. I suspect that neufer's indigestible roughage is a lot easier to take, for most people.
That's why you became a Pharmacist, Ron? I would have thought it was because you liked to try and decode Doctors handwriting.

De58te wrote:I noticed a discrepancy concerning events that contradict the absolute speed of light in a vacuum. In the link saying "opposing jets are blasting out" we find that on February 2014, Herbig-Haro 24 was some 1,500 light-years away. In today's APOD we learn that H-H 24 is 1,300 light-years away. That means in just under 2 years, H-H 24 has traveled almost 200 light-years closer to Earth! Shouldn't this take 200 years even if H-H 24 were traveling at the speed of light? My Gawd, at this rate Herbig-Hero 24 will arrive at Earth in about 13 years!

How much thrust would those jets produce?

If they didn't balance would the protostar go careering off out of the dust cloud?
