Two-faced star baffles science due to its strange appearance
Janus is a white dwarf, and it is the first time a solitary star has been observed that appears to have developed two faces. As…
The star Betelgeuse has increased its brightness by 50% again by questioning scientists about when it will actually explode as a supernova.
Whenever something happens to Betelgeuse, speculation about its supernova explosion immediately begins. It would certainly be an incredible sight to behold, and we are far…
Astrophysicists solve a puzzle of massive galaxies
A new theoretical model reveals an excess of massive galaxies, in contrast to previously accepted theories strophysicists at the Hebrew University of Jerusalem (HU) may…
Black holes in quantum state break the limits of the strange
They would help to achieve a unifying theory between general relativity and quantum mechanics, capable of explaining the nature of the Universe at all its…
