Two intermediate polars investigated by astronomers
By analyzing the long-term, high-cadence continuous photometry from NASA's Transiting Exoplanet Survey Satellite (TESS), astronomers have investigated UU Columbae and Swift J0939.7-3224—two intermediate polars. Results of the study, presented July.....»»
The PLATO mission could be the most successful planet hunter ever, scientists believe
In 2026, the European Space Agency (ESA) will launch its next-generation exoplanet-hunting mission, the PLAnetary Transits and Oscillations of stars (PLATO)......»»
Hubble watches an extreme exoplanet being stripped by its star
A Neptune-sized planet orbits close enough to its star that it is bombarded by dramatic flares which cook the planet with radiation and strip its atmosphere......»»
New "super-Earth" orbiting M-dwarf star discovered
An international team of astronomers reports the discovery of a new "super-Earth" exoplanet with NASA's Transiting Exoplanet Survey Satellite (TESS). The newfound alien world, designated TOI-1680 b, is about 50% larger than the Earth and orbits an M-.....»»
Does this exoplanet have a "sibling" sharing the same orbit?
Using the Atacama Large Millimeter/submillimeter Array (ALMA), astronomers have found the possible "sibling" of a planet orbiting a distant star. The team has detected a cloud of debris that might be sharing this planet's orbit, which they believe co.....»»
