The Gaia spacecraft has revealed that strange tsunami-like earthquakes are shaking some stars in our galaxy

The Gaia spacecraft has revealed that strange tsunami-like earthquakes are shaking some stars in our galaxy

 


Unusual earthquakes Among the many new discoveries made by Gaia, a mission was launched in 2013 to create an “accurate and complete multi-dimensional map of the Milky Way”. The European Space Agency on Monday released the third set of data from the spacecraft, revealing new details about the nearly two billion stars in our galaxy.

Connie Aerts, a professor at the Institute of Astronomy at the University of Leuven in Belgium and a member of the GIA Collaboration, a group of 400 researchers working on data from the project, told ESA News Release.

The agency described the stellar oscillations observed by Gaia as “large-scale tsunamis” that changed the shape of the stars. Gaia was not originally designed to detect this phenomenon but was able to discern strong motion on the surface of thousands of stars, including some places where stellar earthquakes have rarely been seen before.

Previously, Gaia detected radial oscillations – divergent motions from a common point – that caused some stars to periodically bulge and contract while maintaining their spherical shape. The newly discovered oscillations were non-radial.

Gaia is uniquely located approximately 930,000 miles from Earth in the direction opposite to the Sun. The spacecraft carries two telescopes that can survey our galaxy from a location called Lagrange Point 2 or L2. At this point, the spacecraft is able to stay in a fixed place due to the balance of gravitational forces between the Earth and the Sun.

This also means that the spacecraft does not interfere with Earth’s light, and can use minimal fuel to stay stationary. The vantage point allows Gaia to have unrestricted views and constantly survey our galaxy.

“Using this amazing database, we can build a comprehensive picture of the Milky Way and delve into its amazing history of formation, seeing first-hand evidence of past violent interactions with other galaxies, and inner swarms of intense star formation along[the Milky Way]Nicholas said. Walton, a research fellow at the University of Cambridge’s Institute of Astronomy and a member of the ESA Gaia Collaboration, is in the current situation.

Much of the latest information about the Milky Way has been revealed by spectroscopic data from Gaia, which resulted from a technique in which starlight is broken down into its component colors, like a rainbow.

The data collected by Gaia includes new information about the chemical composition, temperatures, mass and age of stars, as well as the speed at which they are moving toward or away from Earth. Detailed information has also been released about more than 150,000 asteroids in our solar system and space dust – what lies between the stars.

George Seabrook, Senior Investigator in the Mullard Space Science Laboratory at University College London, said in a statement issued by the Royal Astronomical Society.

“The more stars we know about their chemistry, the better we can understand our galaxy as a whole. Gaia’s chemical catalog of six million stars is ten times larger than previous Earth’s catalogs, so this is really revolutionary. Versions of Gaia data tell us where the stars are. And how they move.” “We now also know what many of these stars are made of,” Seabrook said.

About 50 scientific papers based on Gaia data will be published on Monday; Some will appear in a special issue of the Journal of Astronomy and Astrophysics.

“Unlike other missions that target specific organisms, Gaia is a survey mission,” said Timo Prosti, ESA’s Gaia project scientist.

“This means that while scanning the entire sky with billions of stars many times, Gaia is bound to make discoveries that other more specialized missions will not miss,” Prostie said. “This is one of its strengths, and we can’t wait for the astronomy community to dive into our new data to discover more about our galaxy and its surroundings than we ever imagined.”
