Astronomers study the orbits of a sextuplet system, an absurdly complex arrangement of six stars in orbit around one another, in order to measure their masses once and for all.
Protoplanetary disks don’t exist in isolation; when young stars pass each other by, their gravitational encounter can disrupt, or maybe even kickstart, planet formation.
Planet formation is dynamic, and different planet formation models can produce dramatically different planetary atmospheres. Today’s bite discusses a new framework developed to tackle this problem, and shines some light on the formation of the exoplanet HR 8799e.
Herald of the Change: A microlensing Jupiter-analogue spotted in K2 data portends Roman’s yield of new planets
Astronomers have just found Jupiter’s twin in a distant solar system. Their discovery technique may surprise you, and might just be the most important method for discovering Earth-like exoplanets in the next decade…
How do moons form in the universe? Astronomers recently gathered direct evidence for the formation of moons around exoplanets!
