The “Dark Matter” has received yet another blow as scientists have detected a very low mass, faint star in a star cluster for the first time.
‘Dark Matter’ is a theoretical substance, which was undetected by telescopes on earth, but thought by some scientists to account for up to three quarters of the mass of the whole universe.
Until now, it was merely assumed that low-mass, faint stars must exist. Even the most powerful high technological telescopes fails to recored low-mass, faint stars.
Together with researchers from Poland and Chile, a Swiss astrophysicist from the university of Zurich has now detected a low mass, faint star in globular cluster M22. The star was seen using a strange gravitational effect called Microlensing.
The measurements were carried using ESO VLT 8-meter telescope with adaptive optics at the Paranal Observatory in Chile.
“The over all mass of globular clusters can now be explained through the presence of previously undetected low mass, faint stars,” said Philippe Jetzer, a gravitational microlensing specialist from the University of Zurich.
The result indicates that the overall mass of globular clusters might well be explained without enigmatic dark matter.
