Quotes from the news wire:
A series of astronomical observations obtained over the period 1986 to 2018 supports the idea that life is a cosmic rather than a purely terrestrial or planetary phenomenon, these include the detection of biologically relevant molecules in interstellar clouds and comets, mid-infrared spectra of interstellar grains and the dust from comets, a diverse set of data from comets including the Rosetta mission showing consistency with biology and the frequency of Earth-like or habitable planets in the Galaxy.

The modern version of panspermia got a major boost when Australian astronomers Dayal Wickramasinghe and David Allen measured the way light was absorbed by interstellar dust, hoyle and Chandra Wickramasinghe (Dayal’s brother) showed that this was matched almost perfectly by desiccated E. coli bacteria.

If we discover life with radically different biochemistry to that found on Earth, then that would rule out panspermia, nothing I have told you is compelling evidence for panspermia. But there are some odd coincidences that we should consider.
