Tail is growing on a comet visiting from another star

This image composed from multiple exposures and provided by NSF's NOIRLab shows a comet streaking across a star field above the International Gemini Observatory on Cerro Pachon, near La Serena, Chile.

Telescope observations reveal a growing tail on the comet that’s visiting from another star.

The newly released pictures – taken by the Gemini South telescope in Chile late last month – are the most detailed yet of the recently discovered comet.

They show a wide coma of dust and gas around the ice ball as it speeds toward the Sun, and also a tail that’s more extended than it was in previous shots.

These new images confirm that the comet is becoming more active as it plows harmlessly through our solar system, according to the National Space Foundation's NoirLab, which operates the telescope.

It’s only the third known interstellar object to venture our way.

As of Thursday, the comet known as 3I-Atlas was 384 million kilometres from Earth and growing ever nearer, according to NASA. It will make its closest approach to the sun at the end of October and then pass closest to Earth in December from 269 million kilometres away — farther from Earth than the Sun.
