NASA captured new pictures of milky way

NASA’s Chandra X-ray Observatory is marking 20 years since the Space Shuttle Columbia launched it into space on July 23, 1999. The agency released a series of gorgeous, new Chandra images to celebrate.
Chandra is built to see X-ray emissions, making it perfect for observing hot stuff like stars and galaxy clusters. The telescope’s unique vision generates colorful images that highlight tumultuous processes happening among the stars. Researchers often combine Chandra’s viewpoint with that of other telescopes, including Hubble.
All of the new images are lookers, but Chandra’s view of Sagittarius A*, the super massive black hole at the center of our Milky Way galaxy, is a real eye-opener.
The psychedelic composite image shows “clouds of gas at temperatures of millions of degrees, neutron stars and white dwarf stars tearing material from companion stars and beautiful tendrils of radio emission.” It combines Chandra’s X-ray data in green and blue with radio data seen in red from the MeerKAT telescope in South Africa.
NASA also released a composite image of massive star Cygnus OB2 that combines Chandra observations with data from two other telescopes. This bright, wild view shows how this star is sending out high-energy winds.
“These violent winds can collide or produce shocks in the gas and dust around the stars, depositing large amounts of energy that produce X-ray emission that Chandra can detect,” according to NASA.
In 20 years, Chandra has taken 2,700 trips around the Earth and traveled more than 1.5 billion miles (2.4 billion kilometers).
