Comet originating from an alien star demonstrates tail development

The 3I/ATLAS comet, the third known interstellar object to visit our solar system, is speeding towards the Sun and making its closest approach to Earth in December. This fascinating celestial body was recently observed by the Gemini South telescope in Chile, with the newly released pictures offering the most detailed view yet of the comet.

As the comet moves closer to Earth, its activity is increasing, according to the National Space Foundation's NoirLab. One of the most noticeable changes is the extension of its tail, which was observed in the newly-released images. The comet, an ice ball, also has a wide coma of dust and gas surrounding it, features that make it a captivating sight in the night sky.

Currently, the comet is approximately 384 million kilometres from Earth, a distance that will decrease to about 269 million kilometres in December. Meanwhile, the distance between the comet and the Sun will be less than its distance from Earth, with the comet making its closest approach to the sun at the end of October.

Despite its close proximity, the National Space Foundation's NoirLab assures us that the comet's journey through our solar system is harmless. So, stargazers, mark your calendars for December, as the 3I/ATLAS comet promises to put on a spectacular show in the night sky. The observations made late last month only serve to whet our appetite for more celestial wonders.
