Astronomers record lunar formation processes around exoplanets – Sidereal Messenger
ksuadminJuly 26, 2021 6
Astronomers have received the first unequivocal observations that the moon formation takes place around an exoplanet in the PDS 70 system, about 370 light years from here, in the constellation Centaur.
In this case, the PDS is not Paulo Maluf’s old party, but it is still from Brazil-sil-sil. It is the acronym for Pico dos Dias Survey, a catalog of young stars identified by the Pico dos Dias Observatory in Itajubá (MG) since 1989.
The PDS 70 system in particular is of great importance. The two well-known planets PDS 70b and c were discovered in 2018 and 2019 through direct observation with the VLT (Very Large Telescope), also in Chile. And last year, an international group used the Hubble Space Telescope to measure the accretion process (growth) of the innermost of them, the PDS 70b. This is why the system is so attractive to astronomers: at around 5 million years ol

Study Suggests Methane Could Be A Clue Of Life On Saturn’s Moon – Sidereal Messenger

Little Enceladus found a “phosphine” that she could call her own. One group of researchers suggest that the presence of methane in the amounts observed in the water clouds ejected from Saturn’s moon cannot be explained by any known mechanism other than life.
The result is strongly reminiscent of the conclusions of researchers led by Jane Greaves from Cardiff University, Great Britain, who discovered phosphine in the clouds of Venus. They also didn’t believe it was a sign of life, but stated that they didn’t know of any alternative mechanism that could explain the quantities.
