Celestial Object

02 - Full Moon at 19:14 UT
05 - Taurid (south) meteor shower peaks. Active between 25 Sept and 25 Nov.
000 Associated with Comet 2P/Encke.
09 - Moon near Mars (morning sky) at 14h UT. Mag. +0.3.
12 - Taurid (north) meteor shower peaks. May produce the occasional bright fireball.
17 - Leonid meteor shower peaks at 9h UT. Arises from debris ejected by
000 Comet Tempel-Tuttle in 1533. Expect about 25 to 30 meteors per hour under
000 dark skies. Predictions of enhanced activity between 21-22h UT on 17 Nov
000 (favours sky watchers in Asia).
21 - Alpha Monocerotid meteor shower peaks at 15:25 UT. A usually minor
000 shower active 15-25 Nov. Radiant is near Procyon. Predictions of enhanced
000 activity this year. Timing favours Far East Asia, Australia and across the
000 Pacific to Alaska.

The photo was taken by the Hubble Space Telescope and shows a detail of the nebula. This close-up shows a dense cloud of dust and gas, a stellar nursery full of embryonic stars. This cloud is about 8 light-years away from the nebula's central star, not shown in this picture. Located in Sagitarius, the nebula's name means "divided into three lobes".

 Titan Flyby 

Today Cassini Spacecraft has beamed back data containing the closest snapshots of hazy moon Titan. Yesterday's flyby was one the closest encounter ever attempted by the spacecraft during 45 times flybys at the moon. When I checked out the website of NASA today, I was stunned by the unprecedented details recorded in the first picture release today after the flyby. A large white area, called Xanadu, near the south pole of the moon appeared so brialliantly surrounded by dark regions. The white area is thought to be clouds, very thick clouds. The dark regions are still unclear whether it is the ocean of methane liquid (as presumably thought by some scientists) or just geologic impact crater. As the time of writing this post, I can only view two pictures so far at NASA website after the yesterday's closest flyby (at 745 mile from the moon surface).

Here are the interesting facts about Titan just in case you dont know why the moon is so interesting to explore: It is the second largest moon in our solar system after Genymade (Jupiter's moon); it is the only moon in our solar system that has atmosphere (like Earth) and scientists believe Titan's atmosphere is similar to that of early Earth; It is thought to have an ocean of liquid of methane and methane rain (so if it is true, it is the only ocean in our solar system that present outside Earth).
Look at my previous posts for the detail background of the Saturn Mission.

    The Oort cloud, is a postulated spherical cloud of comets situated about 50,000 to 100,000 AU from the Sun. This is approximately 1000 times the distance from the Sun to Pluto or roughly one light year, almost a quarter of the distance from the Sun to Proxima Centauri, the star nearest the Sun. The Oort cloud would have its inner disk at the ecliptic from the Kuiper belt. Although no direct observations have been made of such a cloud, it is believed to be the source of most or all comets entering the inner solar system (some short-period comets may come from the Kuiper belt), based on observations of the orbits of comets.
