NASA News: The Hubble Telescope Detects Extremely Rare "Strange Galaxies" | Science | News



NASA's Hubble Space Telescope has discovered a "special galaxy" that is 130 million light-years away that is larger than the Milky Way. The image was captured by the galaxy called NGC 772 located in the constellation Aries. A noticeable difference between the galaxy and our own is that it does not have a bar, unlike Milky Way which is a barred galaxy.

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

In a blocked galaxy, rods contribute to the formation of stars by penetrating dust and gas into the core of the galaxy.

In galaxies such as NGC 772, this effect is lacking, although there is still plenty of dust and gas around for star formation in other parts of the galaxy.

NGC 772 is also an unusually extended form, which means that it is technically classified as a "special galaxy."

What is distinctive in its shape in this case is its arm in the upper part of the image, which has distorted when twisted and extended.

The shape is caused by the movements of a nearby satellite galaxy, which is gravitationally bound to a larger galaxy and orbiting it. of the Hubble telescope indicates that these galaxies may move too fast to actually be in orbit around our galaxy.

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

The three dark shapes on the planet's surface were the result of three solar eclipses while developing on Jupiter.

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

Ganymede's shadow sits at the far left, followed by Io's shadow just to the right.

You can also see Io's shadow at the far right of the Gas giant.

If you saw the event from Jup iter, 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 one time is an extremely rare event.

The US Space Agency said, "Why is this triple eclipse so unique? Io, Ganymede and Callisto walk around Jupiter at different rates.

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

"Callisto's shadow moves across the planet once for every 20 shadow crossings of Io.

" Add the intersection rate of Ganymede's shadow and the possibility of a triple eclipse becomes even more rare. "
