THE SEARCH MAY BE OVER. THE CURIOSITY ISN’T.

After weeks of observing, analysing, and searching through astronomical data, Artemis ’26: Asteroid Search Campaign has successfully concluded.

What began as data on a screen became an opportunity for our students to take part in authentic astronomical research, working with real observations from the Pan-STARRS telescope and contributing to the global International Astronomical Search Campaign.

Behind every dataset was a student asking questions.
Behind every observation was a possibility.
And behind every search was the willingness to look a little further into the unknown.

The mission concludes. The search continues.

Social Sky Vol.112

Imagine looking up at the night sky and knowing that, 124 light-years away, there's a world unlike anything in our Solar System. K2-18 b is a giant planet that sits in the "habitable zone" of its star, where temperatures could allow liquid water to exist. What really grabbed scientists' attention was the discovery of water v***r in its atmosphere—an exciting clue that this distant world might have the ingredients needed for life.

The mystery only deepened when the James Webb Space Telescope detected molecules such as methane and carbon dioxide in the planet's atmosphere. Researchers have even found hints of a molecule that, on Earth, is mainly produced by living organisms. It's far too early to claim we've found alien life, but K2-18 b has quickly become one of the most exciting planets ever discovered. Every new observation brings us a little closer to answering one of humanity's biggest questions: are we alone in the universe?

"The important thing is not to stop questioning."
- Albert Einstein-

Beyond every familiar horizon lies another waiting to be crossed.
The time has come to assemble the next generation of explorers.
Through the International Asteroid Search Campaign, Artemis '26 invites you to venture into the unknown, analyze real astronomical data, and join a global effort to uncover the silent travelers that drift through our cosmic neighborhood.

Every expedition begins with a single step. This one begins with a registration form.

The hunt awaits. Register now!

"Somewhere, something incredible is waiting to be known."
-Carl Sagan-

The skies hold wanderers yet unnamed — small worlds drifting silently near our own. Join us as we turn our lenses skyward once more, tracing their paths and adding new discoveries to the record of our solar system.

Presenting the seventh edition of our citizen science initiative, hosted by the Royal College Astronomical Society under the International Asteroid Search Campaign.
