Scientists discover fastest-known star zooming through the Milky Way

Science Scientists discover fastest-known star zooming through the Milky Way A strange invisible force has been pushing galaxies apart faster for billions of years.

Key points

• The study is published in the journal Nature in which astrophysicist Stefan Gillessen remarked: Its orbit will not decay anytime shortly.
• Nonetheless, Sgr A* continued influence exerted on S301 along its orbital path may enable scientists to better measure the black hole's rotation.
• Ruqia Shahid is a reporter specialising in science, focusing on discoveries, research developments, and technological advancements.
• Scientists in a major breakthrough have discovered the fastest-known star in a zoom-whirl orbit near the galactic core and which may support determine black hole's rotational velocity.
• Black holes are gravitational collapse so solid that not even light can escape.

In practice, the star is roughly around 50% more massive and brighter than our sun travels at a speed more than 8% the speed of light, showing stars in our galaxy are not strictly capped as earlier thought.

Notably, the star, 301 is in eccentric orbit around Sgr A* taking regarding 8.7 years to complete an orbit as its nearest approach to the center of attraction, it comes within 12 to 24 astronomical units, where an astronomical unit is Earth's orbital distance from the Sun.

Black holes are gravitational collapse so solid that not even light can escape. Sgr A* owns regarding 4 million times the sun's mass and is located concerning 26, 000 light-years from Earth.

For context, the study is published in the journal Nature in which astrophysicist Stefan Gillessen remarked: "Its orbit will not decay anytime shortly. So, the orientation of the orbit will change but it is not in danger of being swallowed."

"It is not a wobble – like in back and forth – but rather the ⁠star gets pushed onto a slightly different orbit each time it passes the black hole. That means that by observing that change in orbit for another good decade, we should be able to directly determine the spin of the black hole. Such a measurement is unheard of, so far, " Gillessen continued.

Nonetheless, Sgr A* continued influence exerted on S301 along its orbital path may enable scientists to better measure the black hole's rotation. Black holes are believed to spin and measuring it is additionally challenging since black holes emit no light and are imperceptible.

Ruqia Shahid is a reporter specialising in science, focusing on discoveries, research developments, and technological advancements. She translates complex scientific concepts into clear, engaging stories, helping readers understand the latest innovations and their real-world impact through accurate, accessible, and insight-driven reporting.

In short, scientists discover fastest-known star zooming through the Milky Way is the central thread here, and readers can expect follow-up reporting as the picture becomes clearer.
