With its first light successfully gathered I think that this instrument deserve its own topic. This instrument is similar to the Gemini Planet Imager (GPI) and its prime scientific objective is the discovery and study of extra-solar planets (mostly giants, but for closest stars even super-earths are possible under very fortunate conditions). Another objectives are proto-planetary disks, brown dwarfs, evolved massive stars, Solar System and extragalactic science. SPHERE has three instruments: - The Infra-Red Dual-beam Imaging and Spectroscopy (IRDIS) - NIR imager and spectrograph. - The Integral Field Spectrograph (IFS) - NIR spectrograph. - The Zurich Imaging Polarimeter (ZIMPOL) - visible/NIR imaging polarimeter. There are four images from SPHERE which were published as results of "first light" observations - Image of Titan at 1.59 microns: Images of Titan with polarimetric mode (and in visible light): Dusty ring around the star HR 4796A: A very low mass companion star to Iota Sagitarii from IRDIS (left image) and IFS (right image): All images credit: ESO/J.-L. Beuzit et al./SPHERE Consortium -------------------- |

Thank you for the heads up Jackbauer. =)
I can see the moire pattern, and so I agree that Pallas look quite featureless at that resolution. Even so I find it interesting as the remaining large asteroid that have not been closely studied, and perhaps will remain so for quite some time due to the inaccessible inclined orbit. So telescope images might be our best bet for quite some time. |
