Using the Australia Telescope Compact Array (ATCA) and the Atacama Large Millimeter/submillimeter Array (ALMA), an international team of astronomers has observed a supernova remnant known as 1E 0102.2–7219. Results of the ...
Astronomers have found plenty of white dwarf stars surrounded by debris disks. Those disks are the remains of planets destroyed by the star as it evolved. But they've found one intact Jupiter-mass planet orbiting a white ...

Using India's AstroSat spacecraft, astronomers have observed a magnetar known as SGR J1830–0645 during its recent bursting activity. Results of the observational campaign, published October 6 on the preprint server arXiv ...
Modern astronomy holds that all major galaxies (with the Milky Way as no exception) are the accumulation of numerous small mergers. Thus, it should be expected that some of the globular clusters that are now part of our galaxy ...
