NASA News: Hubble Telescope shows 'strange galaxy' which is very rare | Science | News



NASA's Hubble Space Telescope has discovered a "special galaxy" located 130 million light-years larger than the Milky Way. The picture was taken from a galaxy called NGC 772 located in the constellation Aries. One real difference between our galaxy and our galaxy is that it doesn't have blades, unlike the Milky Way which is a galaxies with galaxies.

A beam is a band of bright light caused by a structure of dust and gas that runs along the galactic center.

In barred galaxies, bars contribute to star formation by channeling dust and gas into the galactic core.

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

NGC 772 is also an unusual elongated form, which means it is technically classified as a "special galaxy."

The uniqueness in its form in this case is that its arm is at the top of the image, which has been distorted due to bending and elongation.

Its shape is caused by the movement of nearby satellite galaxies, which are gravitationally bound to larger galaxies and orbiting around them.

Our galaxy also has satellite galaxies including the Great Magellanic Cloud and the Small Magellanic Cloud, but observations made by the Hubble telescope show that these galaxies might 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 galaxy as a large collision can cause the black hole at the center of our galaxy to grow bigger and destroy everything that is nearby.

Three dark forms of the planet's surface are the result of three solar eclipses that take place on Jupiter.

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

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

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

If you watch that event from Jupiter, you will see three months pass right 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 once was a very rare event.

The US space agency said: "Why is this double eclipse so unique? Io, Ganymede and Callisto orbit Jupiter at different speeds.

"Their shadows also cross Jupiter's face at different speeds. For example, the outer moon of Callisto orbits no later than three months.

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

"Add the level of crossing of Ganymede's shadow and the possibility of triple eclipses becoming increasingly rare."
