Imaging alien planets is difficult, and this world may be the least massive planet directly observed outside of the solar system, scientists say.
A sharp new photo released by the European Southern Observatory (ESO) Monday, June 3, depicts the suspected gas giant (called HD 95086 b) circling its young star (named HD 95086) in infrared light. The star has been removed from the image to allow the planet — shown as a bright blue dot at the bottom left of the picture — to shine through.
HD 95086 b was sighted by ESO's Very Large Telescope in Chile. Based on the planet's brightness, scientists estimate that it is only about four or five times more massive than Jupiter. [See Amazing Photos of the Very Large Telescope
