Dark matter is one of nature’s most confounding mysteries. It keeps particle physicists up at night and cosmologists glued to their supercomputer simulations. We know it’s real because its mass

When the news started to spread on July 1, 2025, about a new object that was spotted from outside our solar system, only the third of its kind ever known,

The European Space Agency (ESA) successfully established a transmission-reception optical link with NASA’s Deep Space Optical Communications (DSOC) experiment onboard its Psyche mission, located 265 million kilometers away, using two

On July 11, 2022, the James Webb Space Telescope finished its commissioning and commenced science operations. In the three years since, the powerful infrared space telescope has delivered on its

NASA has selected three instruments to travel to the moon, with two planned for integration onto an LTV (Lunar Terrain Vehicle) and one for a future orbital opportunity.

There’s nowhere to park right now at the International Space Station for NASA’s next Commercial Crew Program launch, but a slot should clear next week, allowing for the launch of

A mystery interstellar object discovered last week is likely to be the oldest comet ever seen—possibly predating our solar system by more than 3 billion years, researchers say.

The Milky Way could have many more satellite galaxies than scientists have previously been able to predict or observe, according to new research. Cosmologists at Durham University used a new

Argentinian astronomers have employed the upgraded Giant Metrewave Radio Telescope (uGMRT) to perform high-resolution radio observations of a nearby spiral galaxy designated NGC 4527. Results of the observational campaign, published

Women and ethnic minority groups are still significantly underrepresented in astronomy and geophysics despite attempts to bring about change over the past decade, research has shown.
