GRB 190114C (Artist’s Impression): New observations from the NASA/ESA Hubble Space Telescope have investigated the nature of the powerful gamma-ray burst GRB 190114C by studying its environment. Gamma-ray bursts are the most powerful explosions in the Universe. They emit most of their energy in gamma rays, light which is much more energetic than the visible light we can see with our eyes. Hubble’s observations suggest that this particular burst displayed such powerful emission because the collapsing star was sitting in a very dense environment, right in the middle of a bright galaxy 5 billion light years away.

Comet 2I/Borisov and Distant Galaxy in November 2019: Comet 2I/Borisov is only the second interstellar object known to have passed through our Solar System. In this image taken by the NASA/ESA Hubble Space Telescope, the comet appears in front of a distant background spiral galaxy. The galaxy’s bright central core is smeared in the image because Hubble was tracking the comet. Borisov was approximately 326 million kilometres from Earth in this exposure. Its tail of ejected dust streaks off to the upper right.

Comet 2I/Borisov at Perihelion in December 2019: Comet 2I/Borisov is only the second interstellar object known to have passed through our Solar System. In this observation, the NASA/ESA Hubble Space Telescope revisited the comet shortly after its closest approach to the Sun. There it was subjected to a greater degree of heating than it had ever experienced, after spending most of its life in the extreme cold of interstellar space. The comet is 298 million kilometres from Earth in this photo, near the inner edge of the asteroid belt. The nucleus, an agglomeration of ices and dust, is still too small to be resolved. The bright central portion is a coma made up of dust leaving the surface. The comet will make its closest approach to Earth in late December, when it will be at a distance of 290 million kilometres.

Side By Side of Hubble’s New 2I/Borisov Observations: Comet 2I/Borisov is only the second interstellar object known to have passed through our Solar System. The NASA/ESA Hubble Space Telescope has recently revisited this comet for two new observations: Left: In this image taken by the NASA/ESA Hubble Space Telescope in November 2019, the comet appears in front of a distant background spiral galaxy.

Map of the Cosmic Web Generated from Slime Mould Algorithm: Astronomers have designed a computer algorithm, inspired by slime mould behavior, and tested it against a computer simulation of the growth of dark matter filaments in the Universe. The researchers then applied the slime mould algorithm to data containing the locations of over 37 000 galaxies mapped by the Sloan Digital Sky Survey. The algorithm produced a three-dimensional map of the underlying cosmic web structure. They then analysed the light from 350 faraway quasars catalogued in the Hubble Spectroscopic Legacy Archive. These distant cosmic flashlights are the brilliant black-hole-powered cores of active galaxies, whose light shines across space and through the foreground cosmic web.
