First possible planet found outside our galaxy, NASA's big discovery created panic
The US space agency NASA has discovered a new planet. It is being speculated that this body could be the first planet to be discovered outside our galaxy. About 5000 exoplanets have been discovered so far, but all of them are located within our Milky Way galaxy. These exoplanets revolve around our own Sun.

This possible planet has been discovered through the Chandra X-ray Telescope. It is located in the Messier 51 galaxy, 28 million light-years away from our galaxy. The exploration of this planet is based on transit. This planet blocks the light of other stars while orbiting one star. This increases its brightness manifold. This is the reason that our telescope discovered this planet located at such a long distance.

This common technique has already been used to find thousands of exoplanets. Dr. Rosanne Di Stefano and colleagues have recorded a drop in the brightness of X-rays from an object known as an X-ray bright binary. These objects typically contain a neutron star or black hole that draws gas from a closely orbiting companion star.

This team used this technique to detect exoplanets in a binary system named M51-ULS-1. Dr Di Stefano of the Harvard-Smithsonian Center for Astrophysics in Cambridge, US, told BBC News that the method we have developed and implemented is currently the only correct way to search for planet systems in other galaxies.

Dr. Di Stefano said techniques so successful for finding exoplanets in the Milky Way tend to break down when looking at other galaxies. This is partly because the large distances involved reduce the amount of light reaching the telescope. This also means that due to the distance we see many objects in a small space. This makes it difficult to identify individual stars.

Scientists who discovered the planet have admitted that they need more data to prove their claim. The research paper related to this discovery has been published in the famous science journal Nature Astronomy.
