Orbiting Rainbows: Using 'Glitter Clouds' to Search For and Image Exoplanets

The search for exoplanets may one day get a lot more glittery. It sounds a bit like science fiction, but a new NASA proposal called Orbiting Rainbows would use glitter-like materials to help image some of those far-away worlds, which could enable high-resolution imaging at a fraction of the cost.

The Case of the Exocomets Around Beta Pictoris

An artist’s impression showing exocomets orbiting the star Beta Pictoris. After analyzing archival observations that had been made with the HARPS spectrograph at ESO’s La Silla Observatory in Chile, astronomers have discovered two families of exocomets around this nearby young star.

First Direct Imaging of Exoplanet in Visible Light Obtained by Ground-Based Telescope

Image of the exoplanet Beta Pictoris b made with the Magellan Adaptive Optics (MagAO) VisAO camera. This image was made using a CCD camera, which is essentially the same technology as a cell phone camera. The planet is nearly 100,000 times fainter than its star and orbits its star at roughly the same […]
