A research conducted by a team led by astronomer Peter A. Milne of the University of Arizona published in two articles in the “Astrophysical Journal” shows that Type Ia supernovae can be divided into two groups with different characteristics. For years, astronomers had thought that their brightness depended almost exclusively on their distance. This can have consequences on our knowledge of the universe expansion, also calculated based on this type of supernovae.

NASA is studying the presence of water in the solar system and beyond also in connection with the search for alien life form (Image NASA)

Yesterday in Washington, D.C. there was a NASA panel about water and its connection with the possibility of finding extraterrestrial life. Some scientists summarized the findings of recent decades obout the presence of water in space and exoplanets. According to Ellen Stofan, chief scientist at NASA, in the course of our life we ​​may finally have an answer whether we are alone in the solar system and beyond.

The Hubble Space Telescope photographed a series of ghosts of quasars that existed in the past. They are seen as ethereal green objects in various forms and are the last effects of ancient quasars. These phenomena are very interesting from a scientific standpoint because they can provide information about the past of those galaxies, which were once very active.
