As possibly the galaxy’s (银河) most massive star, Eta Carinae is now engaging in some very unusual behaviour. Australian astronomers, being in the Southern Hemisphere (半球), are able to observe it clearly.
In the 19th century, Eta Carinae was for a time the third brightest star in the sky. It has now become less bright so that binoculars (双筒望远镜 )are needed to see it. “It seems to be brightening and becoming less bright over a period of many years”, said Dr Bob Duncan from the Australia Telescope National Facility.
While it is not unusual for stars to vary in brightness, the period is usually much shorter. “Since 1992 it has become four times brighter, and then last year it began to drop dramatically,” he said.
The problem in observing Eta Carinae is that it has been surrounded by a cloud of gas and dust, making it hard to see the star directly. However, radio waves and infrared light (红外线)can pass through this cloud, so telescopes that receive these wavelengths can
A. it is too far away. B. there is too much dust and gas around it. C. the binoculars are not powerful enough. D. it does not send out infrared light. 我来回答: 提交
