It would *ruin* observations of other stars and galaxies, but when you're surrounded by a sight this awesome, who cares about astronomical targets further afield?

A dedicated scan for signs of aliens in interstellar comet 3I/ATLAS. It would have been silly not to look, says @ScienceAlert. A good read for space buffs:

Interstellar comet 3I/ATLAS is only the third object we've ever seen passing through our solar system from elsewhere in the galaxy. 3I/ATLAS doesn't pose a threat to Earth, and the closest it'll get to our home planet (on Dec. 19) is about 170 million miles—nearly twice the distance between Earth and the Sun.
This image of 3I/ATLAS was taken by our Hubble Space Telescope on Nov. 30, when the comet was about 178 million miles from Earth.
🚀 3I/ATLAS: NOT A SPACESHIP. JUST A COMET.
“Non-gravitational acceleration” doesn’t mean aliens—it means outgassing. A new AAS paper shows interstellar comet 3I/ATLAS behaves like a normal comet, with icy jets giving it a gentle push. Mass, size, acceleration? All ordinary physics.

3I ATLAS: Tails of an Interstellar Comet
How typical is our Solar System? Studying 3I/ATLAS, a comet just passing through, is providing clues. Confirmed previous interstellar visitors include an asteroid, a comet, a meteor, and a gas wind dominated by hydrogen and helium.

Comet Lemmon and the Milky Way
What did Comet Lemmon look like when it was at its best? One example is pictured here, featuring three celestial spectacles all at different distances. The closest spectacle is the snowcapped Meili Mountains, part of the #Himalayas in China.

3I/ATLAS: A View from Planet Earth
Now outbound after its perihelion or closest approach to the Sun on October 29, Comet 3I/ATLAS is only the third known interstellar object to pass through our fair Solar System. Its greenish coma and faint tails are seen against a background of stars in the constellation Virgo in this view from planet Earth, recorded with a small telescope on November 14.

Comet Lemmon's Wandering Tail
What has happened to Comet Lemmon's tail? The answer is blowing in the wind — the wind from the Sun in this case. This continuous outflow of charged particles from the Sun has been quite variable of late, as the Sun emits bursts of energy, CMEs, that push out and deflect charged particles emitted by the comet itself.
