This picture shows the Rosette Nebula (玫瑰星云) taken by the US Hubble Space Telescope. This year marks (标志着) the 35th year of the telescope working in space. NASA, the US space agency, shared Hubble’s findings over the years on April 23. The Rosette Nebula is one of them. It takes up a big area and is about 5,200 light years from Earth. It would take about 6.24 billion (十亿) years to fly there in a plane.
