A 25th May 2020 press release (http://www.esa.int/Science_Exploration/Space_Science/Gaia/Galactic_crash_may_have_triggered_S olar_System_formation) made by the European Space Agency (ESA)
discusses how a new study of Gaia data may add more weight to the notion
that the Solar System may have emerged as a result of one of the events
where the Sagittarius Dwarf Galaxy passed through the Milky Way.

Not the best press report - this section was quoted in the newspapers. Soon as I read it I realised they meant the Sagittarius Dwarf, but this was not made clear. Along with a photo of 47 Tuc. But what else can you expect from the media?
