The mysterious interstellar visitor has suddenly shifted from red to green, defying all expectations and revealing chemical signatures that challenge everything we thought we knew about space objects.
New polarimetric observations reveal that our mysterious interstellar visitor exhibits light-scattering properties never seen before in any asteroid or comet, deepening the mystery of its true nature.
On October 3rd, 2025, our mysterious interstellar visitor will pass within 29 million km of Mars. This historic encounter could reveal whether 3I/ATLAS is harboring technological secrets.
The unusual nickel-without-iron emission from 3I/ATLAS breaks every rule of natural space chemistry. While some propose artificial origins, instrument limitations complicate conclusions.
Two space telescopes reveal 3I/ATLAS has a massive 348,000 km gas cloud and alien chemistry unlike anything in our Solar System. What exactly are we looking at?
