Look at the magnificent spiral galaxy through the Hubble lens

M99 was captured by the Hubble Space Telescope's Wide Field Camera WFC3. This device has two channels:

one for ultraviolet and visible light (UVIS) and the other for near infrared (NIR).

M99 - refers to spiral galaxies withordered structure (grand-design galaxy). In such galaxies, one can see two well-defined protruding spiral arms. The opposite is made up of flocculent galaxies, in which only separate parts of the arms are clearly visible.

According to the ESA, Hubble captured M99 in two dimensions so that researchers could study different astronomical phenomena.

The first series of observations was aimed atstudying the differences between two different types of cosmic explosions: novae and supernovae. New stars, caused by the interaction of white dwarfs and larger stars in binary systems, tend to be much dimmer than supernovae, which are the massive explosion of a dying star. However, as noted, there are astronomical events in the agency that blur the border of brightness between new and supernovae. One such event was investigated by the telescope in M99.

The second study was part of a largera project that studies the connections between young stars and the clouds of cold gas from which they form. Scientists believe that the Hubble data, together with observations from the ALMA telescope in Chile, will provide a better understanding of the formation of new stars.
