Two visits from NASA’s most venerable space telescope offer a stunning galactic portrait.
A newly released image of the hubble space telescope shows the fascinating spiral of a galaxy called M99. Particularly on display are the galaxy’s well-defined stellar arms branching out from the galaxy’s dusty yellow center. The new image, which the European Space Agency published on May 2, is the result of two recent Hubble-led surveys.
The separate observations allowed Hubble’s Wide Field Camera 3 (WFC3) to capture a sharper view of the planet’s prominent star-studded arms. spiral galaxy. The image shows a stark contrast between the radiant bluish-purple hues of the vast dense star regions and the surrounding dark space.

M99, like the Milky Way, is a “grand design galaxy,” meaning that it has particularly pronounced spiral arms. This category includes about 10% of all spiral galaxies, according to nasa.
The bright threads of M99 are 42 million Light years far from Earth.
The Hubble image was the result of two separate surveys of the galaxy. The first research focused on stellar explosions called novae. These explosions, which result from white dwarf stars that extract matter from a larger star, are much less violent than supernovaethat mark the death of massive stars.
However, astronomers also believe that there is an intermediate type of explosion, brighter than a nova but fainter than a supernova.
And previous observations of M99 made in 2010 on Palomar Transitional Facility discovered an object in the spiral galaxy with this kind of intermediate brightness, according to ESA. By refocusing on M99, the scientists tried to discover more information about this detection.
The second observation came from Hubble’s involvement in a large study to explore the connections between young stars and the gas clouds from which they emerged. The galaxy M99 was one of 38 galaxies analyzed with the aim of improving scientists’ understanding of star formation.
