By Leonidas Papadopoulos, on January 14th, 2015 The circumstellar disk around the young star HR 4796A, as imaged by the Gemini Planet Imager, which is mounted on the 8.2-m Gemini South telescope in Chile. These images reveal a complex pattern of variations in brightness and polarization around the HR 4796A disk. The western side (tilted closer to the Earth) appears […]

The planets and moons in our Solar System come in a wide variety of colors, and the natural beauty can be breathtaking. Now, the true color of a much more […]
By Emily Carney, on June 14th, 2013 A gap in the protoplanetary disk of dust and gas whirling around TV Hydrae uncovered evidence of an unseen, growing planet, according to astronomers studying Hubble data.

By NASA, on May 25th, 2013 This image shows the HR 8799 planets with starlight optically suppressed and data processing conducted to remove residual starlight. The star is at the center of the blackened circle in the image. The four spots indicated with the letters b through e are the planets. This is a composite image using 30 wavelengths […]
By Jason Rhian, on November 21st, 2012 This false-color near-infrared image has been processed to remove most of the scattered light from the star Kappa Andromedae (masked out at center).The “super-Jupiter” companion, Kappa Andromedae b (upper left), lies at a projected distance of about 55 times the average distance between Earth and the sun and about 1.8 times farther than […]
