    Astronomers see distant eruption as black hole destroys star

    Researchers at the Department of Astronomy, Stockholm University, contributed to a new study, directly imaging the jet of material formed when a black hole rips a star apart. The results are published in the journal Science.

    Massive star explodes in metal-poor galaxy

    This week's issue of Nature Astronomy tells the story of a massive and metal-poor star that exploded as a supernova. It is located in a distant faint galaxy and the authors suggest that it is the low metal content of the host galaxy that allows such a massive star to explode.

    A cold dawn for the first stars

    This morning, as I was walking from Tekniska Högskolan metro station to AlbaNova through the Siberian cold which has hit Stockholm, I was thinking about even colder temperatures than the -15 C that I felt on my skin. Did you know that the temperature of Universe was only 3 Kelvin (-270 C) when the first … Continue reading A cold dawn for the first stars
