Title:
BHR 71: Stars, Clouds, and Jets
Explanation:
What is happening to molecular cloud [ http://antwrp.gsfc.…] BHR 71? Quite possible, a binary star [ http://antwrp.gsfc.…] system is forming inside. Most stars in our Galaxy [ http://casswww.ucsd…] are part of binary star systems [ http://antwrp.gsfc.…], but few have ever been seen in formation. Recent observations [ http://adsabs.harva…] of dust [ http://antwrp.gsfc.…]-darkened Bok Globule [ http://antwrp.gsfc.…] BHR 71, however, show evidence for two young stars forming deep in the cloud, likely close enough to form a binary [ http://instruct1.ci…]. Isolated BHR 71 [ http://cfa-www.harv…] spans about one light year [ http://www.howstuff…] and lies only about 600 light years away in the southern sky [ http://antwrp.gsfc.…]. The brighter embedded star -- not visible here -- is about 10 times as bright as the Sun [ http://www.nineplan…] and drives the jet [ http://antwrp.gsfc.…] that swept out the empty lane. The above four-color image [ http://cfa-www.harv…] was taken with a Very Large Telescope [ http://antwrp.gsfc.…] in Chile [ http://www.cia.gov/…].
