A team of astronomers has discovered a third planet orbiting the star Beta Pictoris. The new planet, Beta Pictoris d, is 100 times fainter than Beta Pictoris b—the first planet discovered in the same system—and is among the lightest exoplanets ever imaged from the ground. After s

A new exoplanet model screens rocky worlds by their ability to retain atmospheres over geologic timescales, helping narrow the search for potentially habitable planets beyond Earth.

The ESA's dark universe detective spacecraft Euclid, has studied the heart of the Milky Way, creating the largest and most detailed photo of this region ever made.

Astronomers have discovered two "super-puff" exoplanets orbiting the same star that have densities lower than cotton candy, making them the lightest worlds ever seen.

Sub-Neptune exoplanets could have atmospheres so dense and crushing that rock is vaporized to form clouds that trap heat at the surface of the planet.

In the course of studying planets beyond our solar system (6,316 confirmed exoplanets and counting), scientists have discovered some very interesting systems. Consider TOI-201, a compact system populated by three bodies, including a brown dwarf, orbiting on the same plane. The sy

We've talked plenty of times here about the infeasibility of launching a mirror big enough to directly image exoplanets using current rocket fairings—at least as long as we're not sending them 500-plus AU away to a gravitational lensing point. We've also talked at length about th

Pesquisa revela que composição interna de exoplanetas pode desafiar interpretações feitas a partir das atmosferas observadas por telescópios O post Planetas mais comuns da galáxia podem esconder oceanos ‘invisíveis’ apareceu primeiro em Olhar Digital.

Astrônomos descobriram a dupla TOI-791 b e TOI-791 – dois dos planetas gigantes mais "esponjosos" já vistos; entenda a pesquisa O post Astrônomos descobrem planetas gigantes como Júpiter e leves como algodão-doce apareceu primeiro em Olhar Digital.
