The other day, astronomers announced for the first time that they have used NASA’s Hubble Space Telescope to directly measure the mass of an extinct star. The most important issue is that they made this calculation based on Albert Einstein’s general theory of relativity.
Gravitational lensing helps us decode space
The mind-blowing cosmic effect called gravitational lensing, predicted by Albert Einstein more than a century ago, continues to guide scientists today. This method was used for the first time to calculate the mass of an isolated star other than the Sun.
The white dwarf star named LAWD 37 is about 56 percent of the mass of the Sun, according to observations made by the Hubble Space Telescope. It can be easily said that the gravitational lensing method is also successful with this amount, which is quite compatible with the previous estimates.
The fact that the results are similar to the theoretical figures also strengthens the current thoughts of scientists about space. Stating that understanding white dwarf stars is very important for exploring space, scientists say that they have more information about how stars are formed.
Gravitational lensing can be explained as the bending of light under the influence of gravity produced by massive objects such as galaxy clusters. Gravitational lensing has a very important place in astronomy. Because, thanks to these light beams, some celestial objects that would not normally be visible can be observed.
In the future, scientists want to collect information about other stars by using the gravitational lensing method. It is also stated that work has already begun for the white dwarf named LAWD 66.
It is truly admirable that Albert Einstein’s teachings are still being used after a century. So what do you think about Albert Einstein’s work and gravitational lensing? You can share your views with us in the comments section.
