Planets orbit stars, and stars spin, but are these two movements always aligned? Details like this are hidden in the light of the stars, and help astrophysicists to tell the story of distant worlds, writes Charlotte Gehan. Read more
Dust, rocks, ices. They form the impressive rings of magnificent Saturn, but the “Lord of the Rings” is not alone. Found in humbler locations and sizes in the Solar System, rings might also exist around worlds orbiting other stars. But how are we going to know? Read more
There are very weird planets in our Galaxy to choose from. The hard task rests with the astronomers: how to explain such a diversity of worlds? Read more
If you would like to have a really eccentric holiday home, there are very weird planets in our Galaxy for you to choose from. The hard task rests with the astronomers, as Sérgio Sousa, of IA, will explain.
In the next session of "The Universe Online", you will have the opportunity to talk to IA researchers that are on the frontline of the search for a new "Earth".
In a clear night sky, the human eye can see some 3000 stars, all of them in our galactic neighbourhood. What we can’t see is, perhaps, a similar number of planets, outshined by the light of their host star. Is there among them an Earth 2.0? Read more
Learn how astronomers detect planets orbiting other stars, and how they can know, despite the distance, if any of them is similar to Earth, with Pedro Figueira, of ESO and IA (in Portuguese).
