| 説明 | Another take at HH 47, this time from ESO data taken by FORS2/VLT.The universe comes with a lot of surprises and this is one too. These jets are jets of partially ionized materials produced by new stars and are very complex. The jets are bipolar, and a typical shock wave is associated with it.Research shows that they are as long as 0.3 parsecs. This image is a standard SHO composite where H-alpha dominates the picture. Look at the structure clearly here: flic.kr/p/2iDT7snAlso, the integration time for this filter is very long(~4hrs). High Ha emission suggests that this region is enriched in new stars. Look at the nebulosity in the background; it's also pretty rich in Ha emissions. Here is the IR version of the same from HST : flic.kr/p/2gsiXA6Color assignments.Red: SII(FORS2/VLT) (2 hrs 42 mins)Green: H-alpha(FORS2/VLT) (4 hrs 44 mins)Blue: OIII(FORS2/VLT) (2 hrs 24 mins)Credits: ESO/Bipradeep Saha |
