European Space Agency Gaia Discovers Strange ‘Star Earthquake’ / Wion News
JAKARTA, kilat.com- The European Space Agency’s Gaia space observatory has reportedly detected several “earthquakes” bintang“which is similar to an earthquake like a tsunami.
Launched in 2013 Gaia studied the Milky Way and has created a map of the galaxy but has now revealed new information about the star and its chemical composition including the color, age, temperature and brightness of the star.
Gaia saw stellar earthquakes that changed the shape of the stars, according to the observations. The agency said the mission had tracked radial oscillations that made the star swell and shrink while maintaining its shape.
However, he also received a “large-scale tsunami”. Conny Aerts from KU Leuven in Belgium who is a member of the Gaia mission said: “Star earthquakes teach us a lot about stars, especially how they work internally. Gaia opens a gold mine for ‘asteroseismology’ of massive stars.”
In a surprising revelation, Gaia discovers that some of the stars in our galaxy are made of primordial material and others are made of material enriched by previous generations of stars.
“Gaia’s 3rd data release contains new and improved details for nearly two billion stars in our galaxy,” Badan . said European Spaceadds, “in this data set is the largest catalog of binary stars, thousands of Solar System objects such as asteroids and moons of planets.”
The European Space Agency describes stellar earthquakes as tiny movements on the star’s surface that change the shape of the star. Although Gaia was not built for such observations, it was able to see “other tremors that were more like large-scale tsunamis.”
Gaia found strong nonradial stellar earthquakes in thousands of stars, the space agency said, including “vibrations” in stars not seen before.
Gaia also revealed the largest chemical map of the galaxy coupled with 3D motion from the sun’s neighborhood to smaller galaxies, he added. (nda)
