The observable universe is vast, extending about 93 billion light-years across, containing galaxies, stars, planets, and all ...

Scientists say the Universe has no edge, but that doesn't mean it's infinite. A Manchester astrophysicist explains what we ...

NASA’s SPHEREx mission is mapping the entire sky in 102 infrared colors, turning raw space data into a public tool for ...

The spectrum is so vast that it dates back 13.7 billion years to a bright tie-dyed-esque line that shows an actual photo of the edge of the observable universe.

At the edge, we see the leftover glow from the Big Bang — the so-called cosmic microwave background radiation (CMB). But this isn’t some magical edge of the universe. Our cosmos keeps going.

The edge of the observable universe is about 270,000,000,000,000,000,000,000 miles away.. If you drive at a steady 65 miles per hour, it will take you 480,000,000,000,000,000 — that’s 4.8 × ...

The announcement said that Astronomer Maarten Schmidt of Caltech had discovered a quasar (quasi-stellar radio source) racing away from earth at 80% of the speed of light. That brief observation ...

Scientists say the phenomenon could “hint at” new particles or interactions between known particles that haven’t been ...

Astronomers at Johns Hopkins University have created an interactive map of the universe, charting the positions and colors of 200,000 galaxies stretching from here to the very edge of the ...

It means the observable size of the universe is around 93 billion light-years. Our cosmos came into existence after the Big Bang 13.7 billion years ago. Ever since the universe has kept expanding.

A cosmic particle detector in Antarctica has emitted a series of bizarre signals that defy the current understanding of ...
