In summary, In a discussion about the comet ISON, a user shares the latest pictures of the comet from the SOHO satellite and its current distance from the sun. They also provide a link to a live stream of the comet's perihelion and mention that it may be happening in about an hour. Another user asks if Saturn is visible in the pictures, but it is identified as the star Antares. The conversation turns to the potential survival of ISON, with one user quoting a Shakespeare line and another sharing a link to a visualization of the comet's trajectory. The conversation ends with a user expressing their hope for a solar system simulation software.

No, that is the bright star Antares. The "ring" is a CCD camera artefact caused by electrons from oversaturated pixels leaking into adjacent pixels.

Thanks..
But how do you come to know that it was Antares and no one else?

use a planetarium program to see where the sun is amd what the surrounding stars are

Stellarium is a good choice

Was it a Shakespeare line that said?

" the rumours of my early demise have been greatly exaggerated"

haha ... ISON still seems to be reasonably intact ... will be interesting to see how it looks when over the next week or so it gets picked up visually

1. What is ISON?

ISON, also known as Comet C/2012 S1, is a comet that was discovered in 2012. It is named after the International Scientific Optical Network which first spotted it.

2. How close will ISON come to Earth?

ISON will pass by Earth at a distance of about 39.9 million miles on December 26, 2013. This is considered a close approach in astronomical terms, but poses no threat to our planet.

3. Will ISON be visible to the naked eye?

It is uncertain whether ISON will be visible to the naked eye. It has the potential to become very bright as it nears the sun, but it could also break apart and become less visible. It is best to use binoculars or a telescope for optimal viewing.

4. What makes ISON unique?

ISON is unique because it is a sungrazing comet, meaning it will pass very close to the sun on its orbit. This is a rare occurrence and can cause the comet to break apart or become brighter due to the intense heat and radiation from the sun.

5. What can we learn from studying ISON?

Studying ISON can provide valuable information about the composition and behavior of comets. It can also give us a better understanding of the formation and evolution of our solar system. Additionally, studying ISON can help us prepare for potential future encounters with comets or other celestial objects.
