The Gaia telescope of the European Space Agency has spotted 352 asteroids around potential moons.&nbsp;

According to the scientists, these asteroids did not have any companions and hence were what is known as "binary asteroids".

Because of the ultra-accurate astrometric data of the telescope, the scientists were able to find signs of tiny rocks flying around huge asteroids.&nbsp;

According to the ESA, this also proves the ability of Gaia to conduct 'blind' searches for finding unknown candidates and work like an asteroid explorer.

After the findings are confirmed, the 352 binary asteroid candidates will be added to the list.&nbsp;

Scientists are interested in binary asteroids because they have clues about the ancient universe and help astronomers study how various bodies were formed in space.

<h2>Why are binary asteroids important for scientists?</h2>

The study's lead author, Luana Liberato, said that it is difficult to find the binary asteroids because of their small size and huge distance.

“Binary asteroids are difficult to find as they are mostly so small and far away from us,” Liberato said.

"Despite us expecting just under one-sixth of asteroids to have a companion, so far we have only found 500 of the million known asteroids to be in binary systems. But this discovery shows that there are many asteroid moons out there just waiting to be found," said Liberato who is also an astronomer&nbsp;at France's Observatoire de la Côte d’Azur.

Since 2013, Gaia has been an asteroid explorer and has all-sky scanning capabilities, because of which it has made various remarkable asteroid&nbsp;discoveries.

By studying these moon-asteroid pairs, scientists can improve their knowledge of the gravitational interactions that influence their stability and orbits.

“Binary asteroids have attracted the attention of the scientific community due to their interesting properties and the significant impact they have on our understanding of the solar system,” the study authors stated.

“Unlike single asteroids, binary systems offer unique insights into many fundamental processes, including the formation and evolution of planetary bodies, collision dynamics, and gravitational interactions," they added.&nbsp;

ESA's Gaia telescope detects 352 asteroids hovering around elusive moons

Scientists have unveiled a remarkable map detailing approximately 1.3 million active supermassive black holes in three-dimensional space, offering an unprecedented glimpse into the "largest-ever volume of the universe."

Led by researchers at New York University in the US, this monumental achievement promises to revolutionise our understanding of the cosmos.

At the heart of galaxies, these supermassive black holes wield immense gravitational influence, voraciously consuming nearby gas and material. This cosmic feeding frenzy gives rise to luminous disks known as quasars and dazzling jets of light, observable by telescopes from afar.

"We were able to make measurements of how matter clusters together in the early universe that are as precise as some of those from major international survey projects," remarked lead author Kate Storey-Fisher from the Department of Physics at New York University. It is "quite remarkable given that we got our data as a 'bonus' from the Milky Way-focused Gaia project,"&nbsp;Storey-Fisher added.&nbsp;

European Space Agency's Gaia space telescope, originally designed to map stars within the Milky Way, inadvertently captured data on objects beyond our galaxy's bounds, including quasars and distant galaxies.

Breakthrough black hole map reveals vast expanse of universe

The European Space Agency's Gaia space observatory has reportedly detected several "starquakes" which are similar to tsunami-like earthquakes.

Gaia which was launched in 2013 studies the Milky Way and has created a map of the galaxy but it has now revealed new information about stars and their chemical composition including the colour, age, temperature and brightness level of stars.

European Space Agency's Gaia discovers strange ‘starquakes’

A new study has revealed that satellite galaxies may have vanished from the Milky Way.

The Milky Way began to form relatively soon after the Big Bang explosion that marked the beginning of the universe some 13.8 billion years ago.&nbsp;

The sun, located roughly 26,000 light-years from the supermassive black hole residing at the center of the galaxy, formed about 4.5 billion years ago.

Subsequent galactic mergers were instrumental in configuring galaxies existing now.

Gaia satellite, operated by the European Space Agency, has conducted a new analysis which shows most of the galaxies in the Milky Way are actually relatively new to the area.

The study, led by astrophysicist François Hammer of the Paris Observatory in France, has been published in The Astrophysical Journal.

''We conclude that due to their unequaled high energies and angular momenta, most dwarfs cannot be long-lived satellites, and if they could be bound to the Milky Way, they are at first passage, i.e., infalling less than 2 billion years ago,'' he said.&nbsp;

Sagittarius, a ''dwarf'' galaxy 10,000 times less massive than the Milky Way, has passed twice through our galaxy’s immense disk containing most of its roughly 100 billion stars.

Until now, the understanding of the galaxy’s shape had been based upon indirect measurements of celestial landmarks within the Milky Way and inferences from structures observed in other galaxies populating the universe.

''The Milky Way is a big galaxy, so its tidal force is simply gigantic and it's very easy to destroy a dwarf galaxy after maybe one or two passages,'' Hammer said.

Study reveals satellite galaxies may have vanished from Milky Way

Researchers have discovered a huge snowman-shaped star with a unique atmospheric composition.

The enormous white dwarf star is known as WDJ0551+4135 and is thought to have resulted from the merger of two so-called white dwarf stars that often explode as powerful supernovas.

Usually, they're small and lightweight but this star is 1.14 times the mass of our sun which is nearly twice the average mass of a white dwarf star.

"This star stood out as something we had never seen before," said Mark Hollands, lead study author and postdoctoral researcher at the University of Warwick's department of physics.

''Initially, these observations didn't make any sense. The only way you can explain it is if it was formed through a merger of two white dwarfs," he added.
