Scientists have found a group of ancient stars orbiting close to the center of our galaxy that may have formed in just the first billion years of the universe. That’s news because old stars are generally only found around the very edges of the Milky Way within the 150+ globular clusters—also called “galactic wanderers”—which may be linked to supermassive stars.

The Pristine Inner Galaxy Survey (PIGS), which reported their results at this week’s National Astronomy Meeting 2023 at Cardiff University in Wales, UK, were looking near the galaxy’s center because galaxy formation models suggest that there ought to be ancient stars there—though very few have ever been seen before.

Most ancient stars we know of are found around the halo of our Milky Way galaxy, but a new study has discovered many close to the galaxy’s heart.

The sun emitted a solar flare this week that was strong enough to cause radio blackouts on Earth — and it reportedly did.

NASA’s Solar Dynamics Observatory captured an image of the event, which showed a bright flash in the top right area of the sun. The flare was classified as a X1.0 flare, which means it is in the most intense class of flares, according to the agency.

The flare peaked at 7:14 p.m. Eastern Time on July 2, NASA said. It erupted from a sunspot that is seven times the width of Earth, according to Space.com, a website that chronicles news and events in space.

What lies underneath Mars’ surface? Space scientists have long been curious about whether Mars’ core is solid or liquid.

A team of experts led by the Royal Observatory of Belgium has discovered that Mars most likely has a liquid core.

The ground-based space station comprises multiple chambers that simulate different environments, ranging from the lunar surface to microgravity.

China has developed first-of-its-kind space station simulators to conduct various experiments and test instruments on Earth, as per the South China Morning Post (SCMP)

Reportedly, the researchers have already begun the first experimental operations of this project, known as the ground space station.

Because of a peculiar effect velocity has on the appearance of the passage of time, our observations make it seem like time ran slower when the Universe was just a baby.

At least, that’s how it appears to us, at a light travel time of nearly 13 billion years away. This is called time dilation, and astrophysicist Geraint Lewis of the University of Sydney in Australia and statistician Brendon Brewer of the University of Auckland have seen it in the early Universe for the first time by studying the fluctuations of bright galaxies called quasar galaxies during the Cosmic Dawn.

Because of accelerating expansion of the Universe, they have found, we see those fluctuations unfold at a rate five times slower than if they were occurring nearby.
