Science Journalism is neither science nor journalism. (sigh?) Hermaphrodites are neither men nor women. ( and while on that they could not be sexists by design right? )
Comet ISON (image below) seen recently, falling in deep space towards sun and eventually completely annihilating itself from observation. Its a comet that was a deep-space-ice-berg melting off and losing its trajectory from the gravity and heat of sun. (are comets as old as we begin observing them or a billion years old from their genesis in the solar system?)
TOI says comet ISON is 1 years old. In that, I am 2 months old because you knew me 2 months ago. In the same article they also say comets are formed from a system 1 billion years ago.
1. It was barely a year old.
2. Comets are balls of dust and ice from the formation of the solar system billions of years ago.
And here is more to ISON, for knowledge, and the evidence from other science journalism how the age of multi-billion years for a comet is consonant with the age of the Universe itself.
Ison has come from the Oort cloud, a belt of comets on the very edge of the Solar System, where it has been for the last 4.6 billion years. The comet is a ‘sun-grazer’, passing so close to the Sun that it heats to over 2,760 degrees centigrade (5000 degrees Fahrenheit).
It passes so close to the star -travelling at 234 miles a second – there is a risk the ball of dust and ice could break up.
