  • New evidence in support of the Planet Nine hypothesis

    Enrique Sacristán | 11 July 2017 10:21

    Last year, the existence of an unknown planet in our solar system was announced. However, this hypothesis was subsequently called into question as biases in the observational data were detected. Now Spanish astronomers have used a novel technique to analyse the orbits of the so-called extreme trans-Neptunian objects and, once again, they point out that there is something perturbing them: a plan...

  • Extreme trans-Neptunian objects lead the way to Planet Nine

    In the race towards the discovery of a ninth planet in our solar system, scientists from around the world strive to calculate its orbit using the tracks left by the small bodies that move well beyond Neptune. Now, astronomers from Spain and University of Cambridge have confirmed, with new calculations, that the orbits of the six extreme trans-Neptunian objects that served as a reference to anno...

  • The mystery about the Chelyabinsk superbolide continues three years later

    In 2013 February 15, the approach of asteroid (367943) Duende to our planet was being closely monitored by both the public and the scientific community worldwide when suddenly a superbolide entered the atmosphere above the region of Chelyabinsk in Russia. Three years and hundreds of published scientific studies later, we are still looking for the origin of such unexpected visitor, that caused d...

  • Trans-Neptunian objects suggest that there are more planets in the solar system

    SINC/Enrique Sacristán | 13 January 2015 09:55

    There could be at least two unknown planets hidden well beyond Pluto, whose gravitational influence determines the orbits and strange distribution of objects observed beyond Neptune. This has been revealed by numerical calculations made by researchers at the Complutense University of Madrid and the University of Cambridge. If confirmed, this hypothesis would revolutionise solar system...
