Interstellar comet 3I/ATLAS is now on its way out of our solar system, never to return.
A mystery interstellar object discovered last week is likely to be the oldest comet ever seen – possibly predating our solar system by more than three billion years, researchers say.
We report initial observations aimed at the characterization of a third interstellar object candidate.
The first discovered interstellar small object, `Oumuamua (1I/2017 U1), presents unique physical properties of extremely elongated geometric shape and dual characteristics of an asteroid and a comet.
The interstellar object population of the Milky Way is a product of its stars. However, what is in fact a complex structure in the Solar neighbourhood has traditionally in ISO […]
Panspermia is the hypothesis that life originated on Earth from the bombardment of foreign interstellar ejecta harboring polyextremophile microorganisms.
A research team led by a Yale astronomer has some advice for our next close encounter with a wandering, interstellar object. Check its X-rays on the way out. Since 2017, […]
Science offers the privilege of following evidence, not prejudice. The first interstellar object discovered near Earth, Oumuamua, showed half a dozen anomalies relative to comets or asteroids in the Solar […]
It’s the first time a visitor from another star system has been seen nearby. But what is it? An asteroid, a comet … or an alien artifact? Scientists at the […]
A telescope in outback Western Australia has been used to listen to a mysterious cigar-shaped object that entered our Solar System late last year. The unusual object–known as ‘Oumuamua–came from […]
