NASA News: Hubble Telescope Identifies 'Peculiar Galaxy' extremely rare | Science | News



NASA's Hubble Space Telescope spotted a "peculiar galaxy" located 130 million light-years away, which is larger than the Milky Way. The image was captured from the galaxy called NGC 772, located in the constellation of Aries. One notable difference between the galaxy and ours is that it does not have a bar, unlike the Milky Way, which is a barred galaxy.

Bars are bands of bright light caused by dust and gas structures that run along the center of galaxies.

In a barred galaxy, the bars contribute to the formation of stars by channeling dust and gas into the nucleus of the galaxy.

In galaxies like NGC 772, this effect is absent, although there is still a lot of dust and gas for star formation in other parts of the galaxy.

The NGC 772 is also an unusual stretched shape, meaning it is technically classified as a "peculiar galaxy".

The peculiarity of its shape in this case is the arm at the top of the image, which distorted as it twisted and stretched.

The shape is caused by the motions of a nearby satellite galaxy, which is gravitationally linked to and orbiting a larger galaxy.

Our galaxy also has satellite galaxies, including the Large Magellanic Cloud and the Small Magellanic Cloud, but observations made by the Hubble telescope suggest that these galaxies may be moving too fast to actually orbit around our galaxy.

However, it is believed that these orbiting galaxies could cause the end of ourselves, as a major collision could cause the size of the black hole in the center of the galaxy to increase, destroying everything nearby.

The three dark forms that the surface of the planets were the result of three solar eclipses unfolding simultaneously on Jupiter.

According to NASA, the shadows are the solar eclipses of the largest moons of Jupiter, Io, Ganymede and Callisto.

Ganymede's shadow is on the far left, followed by Io's shadow on the right.

You can also see Io's shadow on the far right of the Gas Giant.

If you watched Jupiter's event, you would see the three moons pass directly in front of the sun.

Jupiter, unlike Earth with only one moon, has 79 known moons.

But even with so many satellites, NASA said the appearance of three eclipses at the same time is an incredibly rare occurrence.

The US space agency said, “Why is this triple eclipse so unique? Io, Ganymede and Callisto orbit Jupiter at different rates.

“Their shadows also cross Jupiter's face at different rates. For example, the outermost moon of Callisto orbits the slowest of the three moons.

“Callisto's shadow moves across the planet once every 20 Io passes.

"Add the shadow crossing rate of Ganymede and the possibility of a triple eclipse becomes even rarer."
