Scientists have found another culprit Desire, But even his experts are confused: it flows through the Milky Way, slightly smaller than Earth.
The researchers published that the Exoplanet could have a mass similar to that of Mars arXiv.org Collection. Rogue planets (without stars) have been found before, but they are very difficult to find.
“Our findings show that low-mass free-floating planets can be detected and characterized by an underground telescope,” said co-author of the study, Principal Investigator Prof. Said Andrzej Udalsky. a Statement.
NASA has detected more than 4,000 exoplanets in total, most of which use the transit method. About 50 of them are believed to be habitable until September 2018 because of their size and correct star orbit to support surface water and, at least theoretically, life.
Transit observations allow astronomers to look at a star and see it fade as another object passes in front of it. This observation will be expanded in October 2021 when NASA launches the James Webb Space Telescope. The telescope was partially delayed due to the corona virus pandemic and Fox News. Previously reported.
Another technique used by researchers in the latest discovery is “gravity microlensing”, which allows experts to see when background objects pass in front of background objects. The foreground object acts as a lens, bending and magnifying the light to reveal certain features of the background object.
Known as the OGLE-2016-BLG-1928 event, it is the smallest microlensing event of all time in just 42 minutes.
“When we first discovered this event, it was clear that it was a very small object,” said co-author of the study. Radosla Poleski added.
“The possibility of observing microlensing is very slim because the three objects, the source, the lens and the observer must be almost perfectly aligned,” added Pressmec Mros, the lead author of the study. “If we only observed one source star, it would take about a million years for the source to be microlensed.”
