Astronomers of the University of Antioquia reconstructed the trajectory of the meteor that hit the sky above Cuba in February 1, 2019 and by doing this found an interesting connection with the Chelyabinsk impact and possibly with other large meteoroid airbursts happening on the Earth every year.

A group of professional and amateur astronomers from the Dominican Republic and Colombia recorded an impact on the Moon during the last total eclipse and now submitted a scientific analysis of their images

Are we in meteor fireball season?  This seems to be the case after the recent reports of large fireballs appearing in the sky of places as far as Detroit (USA) and Hong Kong (China).  

For more than 15 years it has been thought that large exomoons around close-in giant planets could face a terrible fate.

Astronomers from the Harvard-Smithsonian Center for Astrophysics and the University of Antioquia (Medellin-Colombia), have devised a novel method for identifying rings around extrasolar planets (exorings). The method is relatively simple and can be used to rapidly analyze large photometric database and find a list of exoring candidates.
