The starry night and the Great Wall

Fascinating view

My old camera Canon EOS 1500D

By using the camera, the fascinating scenery that is hidden to the naked eye can be revealed.

Beautiful night sky

Not perfect, but not bad for a first attempt

Mira Ceti, the dimmest red giant star

The variations in the color of stars are the direct consequence of their surface temperature and only of this temperature. The hotter a star is, the more bluish colors the star's light spectrum will be.

J1818.0-1607 is one of the youngest stars, with estimated age between 240 and 500 years

Sirius, the brightest visible star in the sky

Quarks is the smallest particle which cannot be broken down further. Quarks can have a positive or negative electric charge, with blue, green or red in colour

Orion is sets of stars visible during winter in the northern celestial hemisphere. Rigel is the brightest star in Orion

Hot stars are gravitationally bound and in orbit each other, one star starts to absorb materials from another, it rotates faster and become flattened, another becomes smaller and loses mass in a stellar wind. Secondary star expands to become red giant, explodes as a supernova, leaving a neutron star

The circle marked TON 618, 40 billion times the mass of the Sun. There is still an argument whether Ton 618 or Phoenix A is the biggest black hole, depending on different measuring method. Phoenix A is huge enough to engulf the Solar System but it can only engulf objects that are extremely close.

ASASSN-14li was a massive star first discovered in 2014 but it is discovered in 2023 that it has been destroyed by the black hole.

Triton is the moon of Neptune. It holds two records, the most distant major moons in the Solar system and the coldest known object in the solar system with an average surface temperature of -391° F.

This is the Large Magellanic Cloud, where give birth of the fastest star HE 0437-5439, it travels at the speed of 2574960 km/h and getting out the fixed orbit around the center of galaxy. It isn't affected by gravitation. It travels faster than SDSS J090745.0+024507, which travels at 2420000km/h.

The star which the arrow pointed is called HD140283, it is the oldest star, it is estimated has the age of 14.4 billion years, which may be even older than the universe. It is about 190 light years far

This brown draft is called Gliese 229B, which is one of the dimmest star in the universe
