Get ready, stargazers! Comet 3I/ATLAS, the interstellar wanderer that had everyone buzzing in 2025, has made its grand return, gracing our morning skies once more. But what's the big deal? Well, the latest images reveal something truly spectacular: its tail is growing longer!
From our vantage point on Earth, Comet 3I/ATLAS was hidden behind the Sun from October 2025. This meant that ground-based and space telescopes were unable to observe it. However, thanks to the watchful eyes of Mars orbiters, astronomers could still track this deep-space visitor, capturing images of 3I/ATLAS even when it was out of our sight.
Now, the comet has emerged from behind the Sun, making its reappearance in the morning sky. New images are already showing us what it's been up to!
Gianluca Masi of the Virtual Telescope Project has been diligently capturing images of 3I/ATLAS since early and mid-November, offering valuable insights into the comet's current state. He and the Virtual Telescope Project are even planning a live stream of 3I/ATLAS on November 17, 2025, so you can witness the celestial show firsthand.
On November 6, 2025, Masi captured an image just after the comet's re-emergence. Despite the almost-full Moon, Masi managed to capture impressive detail. He noted that the target was only 10 degrees above the eastern horizon.
On November 10, 2025, Masi took another image, this time with slightly improved conditions. The comet was now 12 degrees above the eastern horizon, with the Moon about 85 degrees away. Even with the lunar glare, the ion tail of 3I/ATLAS was clearly visible, thanks to the changing geometry.
And this is the part most people miss... As the comet moves into the morning sky, its tail, which was behind the nucleus as seen from Earth at perihelion, becomes increasingly visible.
The following morning, on November 11, 2025, Masi seized a gap in the clouds to capture another image. He observed that the ion tail of the comet was lengthening as the Sun's heat caused its ices to transform into gas, venting into space.
"We could see the ion tail of 3I/ATLAS spanning at least 0.7 degrees, in the northeast direction, as well as an anti-tail pointing east-southeast," he explained.
This interstellar comet continues to amaze us with its celestial dance.
