Construction Site Ahead: Hubble Observes Planet-Forming Circumstellar Dust Disks in Great Detail

A set of high-resolution images of the vast circumstellar debris disks around 11 nearby young stars, which were obtained with the Hubble Space Telescope, have helped astronomers to study their complex and dynamic structure for the first time in great detail. This visible-light survey, called HST/GO 12228, was done with Hubble’s Space Telescope Imaging Spectrograph (STIS), […]

The Case of the Exocomets Around Beta Pictoris

Astronomers Find Earth-Sized Planet Orbiting Alpha Centauri B

Artist’s concept of the newly-discovered planet, Alpha Centauri Bb, in orbit around its parent star, with Alpha Centauri A visible at bottom left and our Sun at upper right. The discovery was made by tracking perturbations in Alpha Centauri B’s movements as small as a baby’s crawl…an astonishing accomplishment when one considers that the […]
