planet candidate

Researchers report the discovery of a second-generation planet candidate accreting onto a white dwarf, according to a Nature publication. If confirmed, the object would be a rare example of a planet forming anew from debris left after the star's original planetary system was destroyed. Astronomers say the finding could reshape understanding of planetary survival and formation around dead stars.

NPR's Planet Money is asking who will win the 2026 Nobel Memorial Prize in Economic Sciences, opening the annual round of speculation over likely candidates and fields. Ahead of the announcement, observers typically weigh recent research trends, past snubs and frontrunners in areas such as macroeconomics, development and game theory. The Sveriges Riksbank prize remains one of the most watched awards in economics, with the winner revealed in Stockholm in October.
