Called CDG-2, this newly identified “ghostly” galaxy may be one of the most dark matter-dominated galaxies ever discovered, with a staggering 99% of its total mass made up of dark matter — a ...

When you gaze up at the night sky, you’re looking back in time. Light from the stars takes years, sometimes millennia, to ...

Using data from the Hubble Space Telescope, ESA’s Euclid space observatory, and Hawaii’s Subaru Telescope, the researchers discovered faint light emitting around the clusters. That light was clear ...

According to researchers, approximately 99 percent of this galaxy's total mass is dark matter.

Astronomers used AI to search 35 years of Hubble data and discovered over 1,300 rare cosmic anomalies hidden in plain sight.

At first glance, it seems impossible: Hubble Space Telescope can capture galaxies billions of light-years away, yet Pluto often appears as little more than a fuzzy disk. The reason comes down to ...

Scientists discovered a distant jellyfish galaxy with star-forming "tails" stretching back 8.5 billion years.

A team of astronomers has identified an extremely faint galaxy called CDG-2, located roughly 300 million light-years from Earth, where an estimated 99% of its total mass is made of invisible dark ...

A newly discovered galaxy with glowing star-filled "tentacles" is rewriting parts of cosmic history.

Hubble constant. The Hubble constant is crucial in understanding the rate of expansion of the universe and, by extension, ...

Most galaxies in the universe glow brilliantly over cosmic time and space. However, a unique type of galaxies remains ...

For the first time, a much younger version of the sun has been caught red-handed blowing bubbles in the galaxy by astronomers using NASA's Chandra X-ray Observatory. The bubble—called an "astrosphere" ...
