There are an estimated ~2 trillion galaxies within the observable Universe. Most are already unreachable, and the situation only gets worse.

This will be the first mission of its kind. “It’s a long way away from the Apollo sites,” Sarah Noble, Artemis I lunar science lead for NASA’s Planetary Science Division, told CNN.

“All six Apollo landing sites were in the sort of central part of the near side (of the Moon). And now we’re going to someplace completely different in ancient geologic terrain.”

Artemis I is scheduled to launch from NASA’s Kennedy Space Center’s Pad 39B on Monday at 8:33 a.m. EDT (1233 GMT).

Astronomers have reconstructed the history of star formation at the center of the Milky Way for the first time, finding that starbirth radiated outwards from the galaxy’s heart.

The results also revealed that most young stars in the densely packed galactic center formed with only loose associations and drifted further apart over the course of millions of years.

Scientists have discovered a beautiful ocean world that looks like it was ripped out of the Star Wars prequels. The exoplanet TOI-1452 b was discovered just 100 light-years from Earth. A new paper on the discovery says that the entire planet is covered by a thick layer of water and that it’s located far enough from its star to possibly support life.

The ocean world was discovered by a team of researchers at the Université de Montréal. Charles Cadieux, the team leader, announced the discovery this week. Cadieux is also a member of the Institute for Research on Exoplanets (iREx).

The planet is just slightly greater in size and mass than Earth. While the fact that this exoplanet is covered in water is intriguing, it’s also located a perfect distance out from its stars to not be too cold or hot. That means that it could potentially support life, though it’s unclear what kind of life might thrive on an ocean world such as this.
