Thiên hà vô hình lao vào Ngân hà
ột thiên hà mà con người không thể nhìn thấy đã va chạm với Ngân hà nhưng nó vẫn giữ được hình dạng.Newscientist cho biết, vào năm 2008 giới thiên văn phát hiện một đám mây vật chất có khối lượng tương đương với khoảng một triệu mặt trời va chạm với Ngân hà. Giờ đây các nhà khoa học đã chứng minh rằng đám mây ấy đủ lớn để trở thành một thiên hà. Nó có chiều dài 11.000 năm ánh sáng, chiều rộng 2.500 năm ánh sáng. Khi lao vào Ngân hà đám mây di chuyển với tốc độ 240 km/s.
