Translate the following two passages into Chinese.(厦门大学2012年研,考试科目:写作与英汉互译)The researchers found that these simulated Milky Ways were mostly green valley galaxies, suggesting that the real Milky Way is in this transitional state too, the team reports in a paper to appear in the Astrophysical Journal.Past outbursts from the massive black hole at the Milky Way"s centre may be to blame for this mid-life crisis. Radiation "burps" produced after matter fell into the black hole could have heated and expelled gas from the galaxy.And there may be a brief burst of star formation in 5 billion years, when the Milky Way is expected to merge with Andromeda, a nearby spiral galaxy whose properties also indicate it is a green valley galaxy, the team says.The merger may send residual gas towards the centre of the merged object, triggering a short stellar baby boom before the galaxy settles into old age, says team member Darren Croton, also at Swinburne. The spiral discs of both galaxies will be destroyed in the collision, he says: " The violence of the merger will cement our place as a red and dead elliptical galaxy. "In case this sounds depressing, he notes that red elliptical galaxies are not completely devoid of activity. "Many of them continue to lead very interesting lives in their retirement, " he says, pointing to a nearby elliptical called M87 that has spectacular jets streaming from its central black hole.
