A | 根据芬兰达勒姆大学和赫尔辛基大学的一项研究，大麦哲伦星云可能在20亿年内与银河系相撞。目前，这项研究已经发表在国际顶级天文杂志《皇家天文学会月报》上。大麦哲伦星云距离银河系约163000光年。

B |     Canberra, Oct 10 (UNI) External Affairs Minister Dr S Jaishankar on Monday held broad ranging discussions with his Australian counterpart Penny Wong on the Ukraine conflict and its impact on the Indo-Pacific region.

The two addressed a joint press conference as they held the 13th India-Australia Foreign Ministers' Framework Dialogue here.

"We have discussed Ukraine and its repercussions in the Indo Pacific region, the progress in Quad, G-20 issues, our trilateral, some things related to IAEA and climate finance sustainable development goals," Dr Jaishankar said.

Wong said India and Australia should resolve issues in the Indo-Pacific region together.

"We spoke about a whole lot of issues -- trade, economy, education, defence and security, clean energy and among the many agreements and understandings we reached. It is in our mutual interest to expand the diplomatic footprint in each other's country," Jaishankar said.

During the 13th Foreign Ministers Framework Dialogue, the two Ministers took stock of the steady progress of the Comprehensive Strategic Partnership, including important Ministerial visits in recent months and agreed to work closely together in Quad, trilaterals, G20, UN and other important forums.

"India and Australia are comprehensive strategic partners. We are Quad partners. We partner in many other ways... We don't want to see any country dominating and any country being dominated," said Wong.

Wong announced that Australia was looking to open a consulate general in Bengaluru "sometime next year."

The visit by Dr Jaishankar is his second to Australia this year. He came in February 2022 to attend the Quad Foreign Ministers' meeting in Melbourne.

Dr Jaishankar also met Australian Deputy Prime Minister and Defence Minister Richard Marles.

"Exchanged views on regional and global security. Our growing defence and security cooperation ensures a peaceful, prosperous and rules based Indo-Pacific," he tweeted.

UNI ASU MR。天文学家先前认为大麦哲伦星云将绕银河系运行数十亿年，甚至可能逃离银河系。研究人员发现，大麦哲伦星云的质量远远超过预期，其轨道能量会由于动态摩擦力而迅速衰减，可能在20亿年内与银河系碰撞并合。模拟结果表明，撞击将给银河系带来毁灭性的灾难。银河系中冬眠的黑洞将被激活，迅速扩大到10倍，质量增加8倍。活跃的黑洞将释放大量高能辐射流。如果喷气式飞机产生的伽马射线到达地球，它将破坏臭氧层并导致大量的生物灭绝。然而，研究人员也发现，太阳系很可能会在撞击中被抛出银河系，抛入一个更大的空间，因此地球将得以幸免。先前的天文学家预测仙女座星系将在80亿年内撞击银河系，这项研究将银河系与其他星系之间可能的碰撞时间提前了60亿年。
