Comet ATLAS C/2025 K1 Breaks Apart – NARIT Images

comet Atlas C/2025 K1 Disintegrates, Captured in Stunning Images by Thai National telescope

A recently discovered comet, designated C/2025 K1 (ATLAS), is rapidly disintegrating as it journeys through the inner solar system, offering astronomers a rare glimpse into the volatile life cycle of these celestial bodies. images captured by the 2.4-meter Thai National Telescope (TNT) on November 21 and 22, 2025, reveal the comet’s nucleus has already fractured into three distinct parts, with the rightmost fragment exhibiting a noticeable decline in brightness.

The comet, first detected in May 2025 by the ATLAS (Asteroid Terrestrial-impact Last Alert System) telescope network, made its closest approach to the Sun on October 8, 2025. This proximity subjected the comet’s nucleus to intense heat and stress, ultimately leading to its fragmentation begining on the night of November 11th.

Did you know? – Comets are primarily composed of ice, dust, and rock. As they approach the sun, these materials vaporize, creating the visible coma and tail.

Observing the Comet’s Demise

The images from the national Astronomical Research Institute (NARIT) showcase the dramatic changes occurring within Comet Atlas.A senior official stated, “The images clearly show the nucleus splitting apart, and the fading brightness of the rightmost fragment is a direct result of this breakup.”

Currently, Comet Atlas has an apparent magnitude of approximately 10.2, rendering it invisible to the naked eye. Despite reaching its closest point to Earth on November 25,2025,astronomers predict little increase in brightness. This is due to a combination of factors, including reduced dust and gas expulsion, and the ongoing disintegration of the comet itself.”The more a comet breaks apart, the less material there is to reflect sunlight, hindering any potential brightening,” one analyst noted.

Pro tip: – Observing comets is best done with binoculars or a telescope, away from city lights. Dark skies enhance visibility of faint celestial objects.

A Window into the Solar System’s Past

Astronomers hypothesize that Comet Atlas originated in the Kuiper Belt, a region beyond the orbit of Neptune. Its current disintegration during its first venture into the inner solar system suggests it may be a relatively pristine object, offering valuable insights into the early conditions of our solar system.

Comets are often referred to as “time capsules” because their composition remains largely unchanged since their formation. Analyzing the chemical makeup of comet Atlas could provide crucial data about the solar nebula – the cloud of gas and dust from which our sun and planets arose.

Thailand’s Leading Astronomical Facility

The observations were made possible by the thai National Telescope, located at the National Observatory on Doi Inthanon, Chiang Mai Province. This Ricci-Chretian reflecting telescope, boasting a 2.4-meter glass diameter, is the largest and most advanced of its kind in Southeast asia.

The facility serves as a hub for astronomical research, hosting researchers from around the globe for over 200 nights of observation annually. The National Observatory also regularly opens its doors to the public through the “TNO Open House” event,

Reader question: – What factors contribute to a comet’s disintegration? What can we learn from studying these events?

Why did Comet Atlas disintegrate? Comet Atlas began to fragment due to intense heat and stress experienced during its closest approach to the Sun on October 8, 2025. This thermal and gravitational stress caused the comet’s nucleus to break apart, a process first observed on november 11th.
