Astronomy last week

The famous Orion nebula, Lemmon comet sweeping through the southern sky are two of the most astounding astronomical images of the past week by the US Space and Aeronautics Agency (NASA).

The clear image of a part of the famous Orion nebula shows that the stellar wind blows fast into slow-moving air currents, creating shock waves, like a fast-moving canoe across a still lake.

The Curiosity Mars probe landed at the Gale meteorite last August and is looking for signs of water flowing on the surface of the Red Planet. It is currently in a low-lying area after finding many traces of dry streams.

The galaxy M106 with its extended arm is 23.5 million light-years away, this is a large spiral galaxy with dark colored dust bands, blue young star nebula, pink star-forming regions and centers with older stars are yellow. Two unusual bands of pink compared to other arms give evidence of a giant black hole spraying matter from the center of the galaxy.

Lemmon comet has just been discovered last year sweeping the southern sky. With an impressive blue halo and a fuzzy tail, this comet is said to contain C2 gas molecules, blue fluorescence under sunlight. The stars form streaks due to long exposure exposures.

Barnard Galaxy is a small galaxy about 1.5 million light years from Earth. It is classified as an amorphous dwarf galaxy, with many young stars alternating with pink hydrogen gas zones, the main material to form new stars.

Exactly 100 years ago, in 1913, a large meteor shower took place in the sky recorded by many documents. One theory is that large meteorites that break into the earth's atmosphere have broken into pieces, forming parallel meteorite streaks that appear simultaneously as the above sketch.
