Comet 3I/ATLAS, the interstellar comet that's been one of the celestial talking points of 2025, has re-emerged into the morning sky, as of mid-November 2025.
Since October 2025, 3I/ATLAS has been behind the Sun, from our perspective on Earth, meaning astronomers weren't able to see it using ground-based telescopes or space telescopes.
They were, however, able to keep tabs on the deep-space comet courtesy of Mars orbiters, which were able to capture images of 3I/ATLAS while it was otherwise not visible from Earth.
Now, 3I/ATLAS has emerged from the other side of the Sun, back into the morning sky and new images show its tail is getting longer.
Gianluca Masi, of the Virtual Telescope Project, has been capturing images of the re-emerged 3I/ATLAS as of early and mid November, and they provide a valuable insight into what sort of condition the comet is in now.
Masi and the Virtual Telescope Project are gearing up to host a live stream of 3I/ATLAS on 17 November 2025, which you can watch via the embed below:
On 6 November 2025, Masi captured the below image, just after the comet re-emerged into the morning sky.
Because the image was taken during almost-full Moon, Masi acknowledged the detail he was still able to achieve with the setup, despite the lunar glare.
"An extremely bright (almost full) Moon was setting," he says, "with the target just 10 degrees above the eastern horizon."
Masi then captured the below image of 3I/ATLAS on 10 November 2025, with conditions somewhat improved.
"The comet was 12 degrees above the eastern horizon, with a bright Moon about 85 degrees from it," he wrote via the Virtual Telescope Project blog.
"Despite that, we clearly detected the ion tail of 3I/ATLAS, thanks to the evolving geometry.
"Now that the comet is moving into the morning sky, its tail – which was behind the nucleus as seen from Earth at perihelion – is more and more visible."
Masi then took advantage of a gap in the clouds to capture 3I/ATLAS the following morning, 11 November 2025.
He notes the ion tail of the comet is getting longer as heat from the Sun causes its ices to sublimate into gas, venting out 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."
This interstellar comet continues to amaze.
