If you are so close to the main star in the solar system, life simply cannot survive
Second Home Just Around The Corner? Probe Finds 'Reservoir', Nasa: Send People Up There By 2040
In our solar system, there are 2 planets in the habitable zone of the solar system, one of which is our home planet Earth, and the other is Mars
How Long Does It Take For The Sun To Go Out Before Humans Notice It? Will It Be 8 Minutes Or 10,000 Years?
The energy released by the sun's nuclear fusion reaction, in addition to making the sun shine and heat, there is an important role, that is, to resist its own gravity
Three Billion Years Ahead Of Time! The Hubble Telescope Has Discovered That The Andromeda Galaxy Has Hit The Milky Way
An in-depth analysis of the light from these quasars using the Hubble telescope has shown that the Andromeda galaxy's "halo" has two nested gas shells, with the "inner shell" extending outward by about 500,000 light-years and the "outer shell" extending by up to 2 million light-years
A Probe That Flew 22.8 Billion Kilometres And Finally Sent Back Pictures That Teach Mankind a Vivid Lesson

Will Jupiter, The 'King Of The Planets' In Our Solar System, Become a Star In The Future?
After the sun evolves into a red giant, the hydrogen in its core is almost completely fused into helium, so the nuclear fusion inside the sun stops, after which the sun loses its internal radiation pressure and continues to collapse, leading to a constant increase in temperature and pressure in its core, while the helium in the central region of the sun is gradually compressed into the condensed state.

Mysterious Circles Have Appeared In The Universe And Scientists Don't Know How To Explain It... Is It The Emergence Of An Advanced Civilisation?
Whichever way you look at it, humans cannot be the only intelligent creatures in the universe. As far as we know, the universe has existed for at least tens of billions of years, so a reasonable speculation is that there is probably an advanced civilization in the universe that is hundreds of millions or even billions of years ahead of humans, and if that is the case, their level of technology is something that we humans simply cannot imagine.
