The first planet of the Galaxy is exposed to "Spider-mousia"
The first planet outside the Milky Way reveals the spider silk horses to help search farther distance outside the outer planetary technology Daily Beijing October 27th (Reporter Liu Xia) reported the Physicalist Network on the 25th, American scientists in the latest "Nature · Astronomy" The magazine wrote that they use the NAST’s Chandra X-ray telescope, perhaps the spider silk mart of the first planet outside the Milky Way.
This candidate is located in the Spiral Star Messya 51 (M51), which found a window to open a window in a further distance. The outer planet is defined as a planet other than the solar system. It has been found in the Milky Way, almost all of these planets are less than 3,000 light years, while the newly discovered suspected external planet is about 2800 Wanuang year.
In the latest research, the team of Rosan Di Stefano, the Harvard Messen, using the XMM Newton satellite of Chandra X-ray telescope and the European Space Agency, with three galaxies outside the Galaxy system X-ray search for the game.
The so-called sun refers to a planet through a star, blocking the stars part of the light, leaving the corresponding characteristics in the spectrum, and scientists have found thousands of outer planets with a lottery event. They searched for 55 systems in M51 and 64 systems in Messay 101, and 119 systems in Messaye 104, eventually discovered this candidate external planet.
This candidate is located in the M51uls1 double star system in M51, which contains a black hole or neutral star.
The data provided by the Chandra telescope found that the current phenomenon lasted for about 3 hours.
Based on this information, the researchers estimate that the candidate series in M51ULS1 is so large, and the distance from the neutron star or the black hole is twice the distance between Saturn and the sun.
Researchers said that more data is needed to verify that it is really a Milky Way outer planet. However, the candidate planet is far from the main star. It will not pass in front of its main star in about 70 years. Therefore, scientists cannot determine their identity in the next few decades. Researchers said they will search for more candidates outside the data in the data.
Chandra telescope acquires at least 20 star data, many galaxies are much more than M51, so you can detect a short-term duration of duration.
In addition, scientists are also expected to observe the Ling Japan with X-rays in the Milky Way, thus discovering near the neighboring new planets in an unusual environment. Source: Science and Technology Daily.
