Space: The Final Frontier. Exploring space developments and theorizing about how humans fit into the universe.

A star older than the universe?
Earlier, scientists found that the metal content of the star HD 140283 was very low, much lower than that of the Sun, as determined by stellar spectroscopy. With a better understanding of stellar evolution, scientists realized that it is a very old star, most likely of group II (our Sun is a group I star), because of its low metal content, which means that it formed when there were not many metals in the universe.

36 light years away, scientists have discovered a "super-Earth".
Some time ago, scientists reportedly discovered a "super-Earth" orbiting a red dwarf star 36 light-years away from Earth, with a mass about three times that of Earth and a rotation period of about 2.4 days.

1500 light years: Black hole "unicorn" to become the closest black hole to Earth?
Astronomers recently discovered the unicorn black hole, which is currently the closest black hole to Earth. It is a small black hole, 1,500 light-years from Earth, with a mass about three times that of the Sun.

Will 3 suns merge and become black holes?
A black hole is a mysterious object that exists in cosmic space. Its gravitational force is so strong that light cannot escape. That is why black holes cannot be directly observed by us.

A brand new black hole will appear!
We all know that there are many black holes in the universe. In addition to supermassive black holes, primordial black holes, and newly discovered intermediate-mass black holes, which are not yet known exactly why they form, massive stars also become stellar-class black holes after collapsing at the end of their lives.

Mercury's metal content is up to 70%, which could be mined by humans for a long time
The development of civilization is inseparable from resources, and without the support of abundant resources, human science and technology could not have made great development. In a short span of more than 200 years, human beings were able to achieve a great leap in science and technology, which is closely related to the abundant metal resources on the earth.

Are the poles of Mars also icy worlds?
When it comes to the Earth's South Pole and the North Pole, everyone's mind will immediately conjure up images of icy skies and snow-capped mountains. So, the Earth's neighbors - Mars, that is, Iron Man Musk said to immigrate to the planet, its north and south poles, and how it is? Will also be the magnificent appearance of snow and ice?

Why don't the aliens come to us?
Since the beginning of the detailed knowledge of ourselves, human beings have never given up longing for the stars and the imagination of "aliens".

How much do you know about the dangers of a trip to Mars?
Astronauts to Mars journey is not like tourists to Switzerland so easy, relaxed, and comfortable, but a journey full of uncertainties and unknown risks of adventure. Astronauts on Mars exploration missions will have to fight for a long time against the stresses of deep space radiation, microgravity, claustrophobic space, and isolation.

There are creatures on Mars?
The Curiosity rover is approaching its 10th anniversary of landing on Mars, and after 10 years of operation, it is still traveling on the lowland edge of the Martian Elysium Plain, having traveled a cumulative distance of 28 kilometers.

Why alien civilizations do not come to Earth
Why is Stephen Hawking already trying to stop China's Eye in the Sky system from sending out messages of exploration to the universe?
