OMEGA Measurements of Southern Polar Cap
The polar caps on Mars consist chiefly of CO2 and exhibit seasonal variations in their coverage. Observations by the OMEGA instrument are challenging current theories on the nature of one particular region of the southern polar cap known as the cryptic region.

Hubble yields direct proof of stellar sorting in a globular cluster [heic0616]
A dedicated study based on Hubble data of the proper motions of stars in one of our Galaxy's densest globular cluster - 47 Tucanae - has provided the best evidence yet, of the process of stellar sorting by mass inside a globular cluster.

Titan Flyby - 25 October 2006
Only 16 days after Titan-19, Cassini returns to Titan for its twenty-first targeted encounter. The closest approach to Titan occurs on Wednesday, 25 October 2006, at 15:58:07 UT at an altitude of 1030 kilometres above the surface and at a speed of 5.99 kilometres per second. The latitude at closest approach is 7.5° and the encounter occurs on orbit number 31.

Hubble observations confirm that planets form from disks around stars [heic0613]
By combining numerous Hubble observations taken over a 3-year period with ground based observations, a team of astronomers led by G. Fritz Benedict and Barbara E. McArthur has deduced the inclination of the nearest exoplanet's orbit around its parent star Epsilon Eridani and found it to be aligned with the star's debris disk.

Double Star and Cluster witness pulsated reconnection for several hours
Using coordinated observations of the CNSA/ESA Double Star and ESA/NASA Cluster missions, a team of European and US scientists reveals new features of magnetic reconnection at the Earth's magnetopause. These results improve our knowledge on how, where and under which conditions the solar wind manages to penetrate the Earth's magnetic shield on the flank of the magnetosphere.

Update on ACS Operations
Hubble's workhorse, the Advanced Camera for Surveys (ACS), resumed science operations on 1 October 2006 with one of its three channels, the Wide Field Channel (WFC), brought back into service. Historically, this channel has accounted for 70-80% of all observations obtained with the ACS. Observations with the WFC form an integral part of the HST science observing plan for next week.
