ALMA starts observing the Sun
Potentially habitable super-Earth K2-3d observed transiting parent star
A group of researchers has observed the first ground-based transit observation of K2-3d — a potentially Earth-like extrasolar planet supposedly within the habitable zone around a bright M-dwarf host star 147 light-years away — using the multi-band imager MuSCAT on the Okayama Astrophysical Observatory’s 1.88-metre telescope.
Record-breaking dwarf satellite galaxy of the Milky Way discovered
An international team has found an extremely faint dwarf satellite galaxy of the Milky Way using the Hyper Suprime-Cam (HSC) on the 8.2-metre Subaru Telescope located at the Mauna Kea Observatory on Hawaii. Named Virgo I, the galaxy lies 280,000 light-years away in the constellation of Virgo. The galaxy may well be the faintest satellite galaxy yet found.
Ancient eye in the sky reveals galaxies
A gravitational lens system has been discovered by undergraduate students examining images from the 8.2-metre Subaru Telescope’s Hyper Suprime-Cam. Dubbed the “Eye of Horus” due to the system’s uncanny resemblance to the sacred eye of the ancient Egyptian goddess, it is formed by a galaxy 7 billion light-years from the Earth bending the light from two more galaxies directly behind it.
‘Birthplace’ of a fast radio burst located for the first time
An international team of scientists led by a Square Kilometre Array (SKA) project scientist has for the first time managed to identify the location of a fast radio burst using a combination of radio and optical telescopes, allowing them to confirm the current cosmological model of the distribution of matter in the universe.
ALMA spots monstrous baby galaxies cradled in dark matter
Astronomers using the Atacama Large Millimetre/submillimetre Array (ALMA) have discovered a nest of colossal baby galaxies 11.5 billion light-years away. The young galaxies seem to reside at the junction of gigantic filaments in a web of dark matter. These findings are important for understanding how enormous galaxies like these are formed and how they evolve into huge elliptical galaxies.
