NASA has released a stunning new image of the irregular galaxy LEDA 6430 captured by the NASA/ESA Hubble Space Telescope.

LEDA6430 It is located in Phoenix, a small constellation in the south, about 15 million light years from Earth.
This galaxy, also known as ESO 245-5 or HIPASS J0145-43, 15,000 light years Across.
“The Hubble image of LEDA 6430 shows a dense starry sky over a background of dust, gas, and light from more distant objects,” Hubble astronomers said in a statement.
“In the image, the stars take up most of the field of view, so it's a little difficult to realize that you're actually looking at a large portion of the galaxy.”
“Another reason why LEDA 6430 is probably a bit difficult to tell is a galaxy is its apparent lack of structure,” the astronomers added.
“We frequently enjoy Hubble's spectacular images of spiral galaxies, which are extremely interesting to watch, in part because the stars, gas, and dust appear to be arranged in an unusually orderly manner. .”
“In contrast, the LEDA 6430 de vaucouleurs system”
“The IB(s)m designation specifically means that the galaxy is irregular (I), banded (B), has a slight spiral structure (s), and is Magellanic (m). ”
“Irregularity is very intuitive in this context; galaxies do not appear to have a regular, ordered structure,” the researchers said.
“In fact, the entire landscape here is covered in stars from this galaxy.”
“The second term means there is a bar-like shape at the center of the galaxy, which is a dense expanse of stars across the center of this image.”
“Paragraph 3 says there are hints of a helical structure, but nothing clear or definitive (hence the 's' in parentheses).”
“Finally, the last term shows that LEDA 6430 is similar to the Magellanic Clouds, two dwarf galaxies that flank the Milky Way.”
Color images of the LEDA 6430 were created from separate exposures taken in the ultraviolet, visible, and near-infrared regions of the spectrum. Hubble's Wide Field Camera 3 (WFC3) Equipment.
Five filters were used to sample different wavelengths. Color is obtained by assigning different hues to each monochromatic image associated with an individual filter.
