Using various spacecraft, astronomers from India and Chile have performed X-ray observations of a peculiar intermediate polar known as TX Columbae. Results of the observational campaign, published September 7 on the pre-print ...
Roughly 5 billion years ago Earth was in the process of forming. Gas and dust gathered with the young sun's protoplanetary disk, likely nudged a bit by the resonant gravitational pull of Jupiter and other large worlds. One ...
