Scientists find direct observational evidence for the existence of black hole accretion wind
Scientists find direct observational evidence for the existence of black hole accretion wind
The Yunnan Observatory of the Chinese Academy of Sciences first discovered the existence of quasi-periodic oscillations in the light variability of a nova
On October 14, the reporter learned from the Yunnan Observatory of the Chinese Academy of Sciences that researchers recently discovered for the first time in China that there is a quasi-periodic oscillation in the light variation of a quasi-nova, and at the same time confirmed that there is a strong wind in such a system.”Astrophysical Journal”, the relevant results are of great significance to the study of the accumulation and evolution of binary stars.
Why is the Nobel Prize in Physics awarded to black holes in 2020?
The 2020 Nobel Prize in Physics was officially announced and awarded to the following three scientists:British scientist Roger Penrose, German scientist Reinhard Genzel and American scientist Andrea Gates.
Astronomers in my country discovered for the first time that there is a quasi-periodic oscillation in the light change of a nova
The reporter learned from the Yunnan Observatory of the Chinese Academy of Sciences on the 11th that for the first time, researchers at the station discovered that the light variation of quasi-novae has quasi-periodic oscillations, and confirmed that there are strong disk winds in such systems. The relevant results are useful for studying the accumulation and evolution of binary stars. It is of great significance.
Great, to realize the use of black hole”echo mapping” to measure the distance of the universe
When you look up at the night sky, how do you know whether the light spots you see are bright and distant, or relatively weak and close? The difference between its true brightness and apparent brightness reveals an object and an observer the distance.
Exciting discovery:Astronomers first discovered the existence of extragalactic planets
Astronomers discovered the first exoplanet in 1992. In the 28 years since then, humans have discovered 4,277 exoplanets, and more than 5,000 are waiting to be confirmed.
If there is an indestructible spacecraft, what will you see when flying all the way into a black hole?
A black hole is the darkest celestial body in the universe, because its gravitational force is so strong that even light cannot escape from its horizon. Therefore, it is impossible for us to directly observe it. If an extremely solid spacecraft flies to the black hole from the outside, we will be on the way What kind of scenery can you see?
