A Gresham College lecture as Visiting Professor of Cosmology, part of the series “The Unexpected Universe“. “In space, no one can hear you scream”. The chillingly accurate tagline of Ridley Scott’s 1979 space horror classic, Alien, is often belied in science fiction movies, forgetting that in space there is no air, and hence no sound.

Today on the arXiv: Light echo gives insight into SNIa dust environment

I noticed this interesting paper using high resolution, multi-epoch images from Hubble to study the time evolution of the aftermath of the explosion of SNIa SN204J, which went off in 2014 in the nearby galaxy M82 (a mere 11 million light years away). The data show the presence of a radially expanding light echo, as well […]
