The Moon has once again become an important playing field. The big difference is that now private enterprise is also involved.

Fernando Ballesteros, researcher at the Astronomical Observatory of the University of Valencia, searches for moons orbiting exoplanets using the Kepler space telescope.

Jerónimo Muñoz, a 16th-century Valencian astronomer, made important observations of the supernova that exploded in 1572, as well as eclipses, stars, and extremely precise maps.

Discovering an Earth-bound object is not the same as avoiding it. For the latter, early detection is crucial. The author considers that we can have an effective space defence system.

The race to discover an exo-moon is nearing interesting times and a discovery might be just around the corner.

At the moment, a manned mission to Proxima Centauri involves a number of problems and challenges that we are still unable to solve.

In April 2021, the ingenuity drone flew within the Martian atmosphere. Its purpose was to demonstrate the feasibility of flight in the tenuous Martian atmosphere.

The year 2020 ended with a potential detection by the Breakthrough Listen project of an artificial signal coming from Proxima Centauri. But there was no indication of structure or modulation in the signal, no evidence that it carried any information.

Fernando Ballesteros discusses the discovery of phosphine on Venus and other historical hypotheses regarding signs of life on other planets.

Can an extraterrestrial organism produce a catastrophic pandemic on our planet? Such a question arises every time we consider bringing samples from other worlds in the Solar System, especially now, amidst the COVID-19 pandemic.
