Certain black holes can have a complex internal structure that could allow photons, particles, and perhaps even planets to orbit the central singularity
Astronomers have measured the diameter of the dwarf planet Eris by catching it as it passed in front of a faint star. This was seen by telescopes in Chile, including the TRAPPIST telescope at the European Southern Observatory
"Congratulations LkCa 15! You've given birth to a proto-exoplanet!"
Usually, running five minutes late is a bad thing since you might lose your dinner reservation or miss out on tickets to the latest show. But when a planet runs five minutes late, astronomers get excited because it suggests that another world is nearby.
Until recently, astronomers were highly skeptical of whether or not planets should be possible in multiple star systems. It was expected that the constantly varying gravitational force would eventually tug the planet out of orbit. But despite doubts, astronomers have found several planets in just such star systems. Recently, astronomers announced another, this time in the trinary star HD 132563.
(PhysOrg.com) -- University of Notre Dame astronomer David Bennett is co-author of a new paper describing the discovery of a new class of planets -- dark, isolated Jupiter-mass bodies floating alone in space, far from any host star. Bennett and the team of astronomers involved in the discovery believe that the planets were most likely ejected from developing planetary systems.
(PhysOrg.com) -- An international team of astronomers today revealed details of a "super-exotic" exoplanet that would make the planet Pandora in the movie Avatar pale in comparison.
