Something massive in space is causing star clusters to disappear. The mysterious invisible cosmic mystery makes scientists look for answers. The Hyad cluster, closest to our sun and 153 light years from Earth, is losing stars at an incredible rate, and scientists believe it is a ‘dark matter substructure, a relic that has the mass of 10 million suns. contains and is made of a mysterious non-luminous substance. “Part of the Hyades cluster has been left bare, without stars.
Tereza Jerabkova leads the team of scientists from the European Space Agency (ESA) who discovered the “Galactic Lump” using data collected by ESA’s Gaia satellite. “This is the amazing thing about the data from the Gaia satellite – for the first time in history we have the chance to look for stellar structures hiding in the vast array of field stars in the galaxy,” Jerabkova said in an interview with Vice. . Many of the stars in the Hyad cluster are visible to the naked eye from Earth, meaning we can see their absence even without a powerful multimillion-dollar telescope.
Over the past 700 million years, the Hyad cluster has undergone several changes, and many of its brightest stars can still be seen on Earth “in the V-shape at the head of the constellation Taurus.” The tremendous amount of changes are due to “inner cluster dynamics as gravitational forces of the greater Milky Way.” Outside forces have evolved what scientists have called “tide tails,” which fly into the galaxy, revealing older and new stars.
Now these “tide tails” are being torn apart by something massive. According to the new study by Tereza Jerabkova and her team at ESA, “a close encounter with a massive galactic nodule may explain the observed asymmetry in the Hyades’ tidal tails.” Jerabkova adds, “We see that stars belonging to the closest cluster move in a way that they shouldn’t move using our known and widely used models.” She further notes that their models could either be far away or the motions changed due to a chunk of dark matter, and this would also be an important discovery ”.
Tereza Jerabkova argues that the mystery “could be a dark matter substructure, also known as a subhalo.” The massive dark matter objects “emerge in the early years of galactic formation” and have been studied by scientists for years now. A black hole would just swallow the stars, but that’s not what’s happening here. Jerabkova says. “the orbits of the stars in the Milky Way are affected / changed by the encounter”, tearing apart some of the “tide tails”. As for this massive galactic beast taking our sun away, scientists say it’s not something to worry about. The interview with Tereza Jerabkova was originally conducted by Vice.
