The interstellar comet 3I/ATLAS is back in view after ducking behind the sun. New images taken from the Lowell Observatory in Arizona capture this exciting moment just in time for Halloween.
Astronomer Qicheng Zhang has been keeping an eye on 3I/ATLAS since it was first spotted in July. He says amateur astronomers can now catch a glimpse of it with small telescopes across much of the Northern Hemisphere. “All you need is a clear sky and a low eastern horizon,” he noted.
3I/ATLAS zooms through our solar system at a staggering speed of over 130,000 mph (210,000 km/h). Since its closest approach to the sun on October 29, researchers have been analyzing its path. They found that the comet underwent rapid brightening as it approached perihelion and appeared distinctly bluer than the sun. This change is likely due to gas emissions that boosted its visible brightness.
Recent studies reveal interesting facts about the comet: it might be 3 billion years older than our solar system! Some astronomers believe it is a typical comet from an unknown system, despite wild speculation about its nature.
As the comet travels away from the sun, scientists expect it to heat up. This will cause the ice on its surface to transform into gas, revealing more about its composition. Observing 3I/ATLAS is crucial for understanding not just its origins but also the history of comets in our universe.
Zhang predicts that in just a week, the comet will be significantly further away from the sun, enabling a variety of larger telescopes worldwide to observe it. The excitement is palpable as the scientific community prepares for the upcoming discoveries about this fascinating celestial object.
