Until March 10 (the day of its perihelion) it continued to approach Sol, and now that it is coming back, on its way back, it can also be observed from the northern hemisphere, including Spain. For this, the first days you will need optical (binoculars) or photographic help and, of course, a horizon free of obstacles and a transparent sky.

It is the conclusion reached by scientists from the California Institute of Technology and NASA, who have just found strong evidence that there is a large ocean of liquid water under the icy surface of this satellite. And, what is more interesting, that it is in contact with the frozen surface and even exchanges chemicals with it. The results will be published in the Astronomical Journal.

An international team of scientists has managed to tie knots with water in a laboratory, just a century after the idea was suggested. The feat, which has been published in 'Nature Physics', paves the way for researchers to study the twists and turns that occur in phenomena such as ionized gases in the solar atmosphere, superconducting materials, liquid crystals and quantum fields described by the elementary particles.
