Planet Rogue has been discovered flying across a galaxy without a star



There is a “fake planet” flying across the Milky Way – a free-floating world with no host star. Is it really a Death Star? The worldview of the villain Marvel Annihilus or Galactus? Planet-sized Unicron transformers? In a newly published study, scientists claim they discovered a fake planet by 2020. It appears to be on the slightly small side as far as the exoplanets, with masses. supposedly between Earth and Mars.

Study co-author Andrzej Udalski, principal investigator of the Optical Gravitational Lens Experiment (OGLE) project run by the University of Warsaw in Poland.

While astronomers have discovered 4,000 alien planets so far – and there may be more spoof planets out there than many with host stars – the discovery of a spoof planet It seems more difficult because there is no light from a host star for scientists to help detect the planet.

Project OGLE, using the Las Campanas Observatory in Chile, discovered the rogue planet using a technique called gravitational microlensing.

As Space.com explains, this planet-hunting method, “involves seeing objects in the foreground pass in front of distant background stars. When this happens, the closer object there is.” can act as a gravitational lens, bending and magnifying the star’s light in ways that can reveal the foreground subject’s mass and other characteristics. “

The lead author of the study, Przemek Mroz at the California Institute of Technology, explained how “extremely thin” the likelihood of such a microlensing event occurring as it requires perfect coupling between the light source, the lens. prospect and observer. “If we were to look at only one source star, we would have to wait nearly a million years to see the source be microfilm,” Mroz said.
