In May 2024, the most powerful solar storm to hit Earth in two decades caused chaos in space as it forced thousands of satellites to fight against thickening atmospheric gases to remain in orbit.

Satellites burning up in Earth's atmosphere are producing chemicals that could thwart the recovery of our planet's protective ozone shield.

Scientists have found that the members of the first all-civilian space mission, Inspiration 4, got genetically younger during their stay in space. But the effects did not last long.

A new report by NASA outlines the most promising approaches to keeping the space around Earth safe and usable for future generations.

The Space Trash Signs project has created "constellations" made of defunct satellites and old rocket parts to draw attention to the worsening space debris problem.

SpaceX's Starship will make space-based solar power cheaper than nuclear, gas and coal-based electricity generation, start-up Virtus Solis believes.

Reflect Orbital plans to launch a constellation of orbiting mirrors to beam sunlight to solar power plants on Earth after dark.

Japan will test solar power transmission from space in 2025 with a miniature space-based photoelectric plant that will wirelessly transmit energy from low Earth orbit to Earth.

A first-of-its-kind lab demonstration shows how solar power transmission from space could work.

Spanish start-up HALO Space has unveiled its capsule design for stratospheric space tourism.

Satellites in low Earth orbit can be hundreds of miles off their expected trajectories when bad space weather hits.

A total solar eclipse is not just an awe-inspiring natural phenomenon; it's an opportunity to expand our scientific understanding of the sun.

SpaceX's Starship uses greener propellant than other rockets, but its environmental footprint could still be substantial if plans for hundreds of launches per year come to pass, experts warn.

"We're surrounding the planet with trash."

Incredible images captured by the Very Large Telescope in Chile reveal unique insights into planet formation around young stars.

NASA's CAPSTONE cubesat is still going strong after 450 days circling the moon in a special orbit chosen for NASA's future lunar space station.

The thicknesses of ice shells covering our solar system's ocean-bearing moons could provide hints about whether these mysterious bodies may harbor life.

Scientists have developed a new computer model that simulates how moon dust behaves in lunar gravity. They hope it will keep future moon exploration robots safe.

One of the Milky Way’s brightest star clusters may have a medium-sized black hole at its heart, groundbreaking radio observations revealed.

Even though the Starlink constellation has grown by about 1,000 spacecraft in the last six months, its satellites made fewer avoidance maneuvers in that period than in the prior half year.

Researchers have just come a step closer to uncovering the secrets of an alien planet that may be the most likely of all known extrasolar worlds to host life.

The brightest fast radio burst ever observed flashed from a group of ancient galaxies, the Hubble Space Telescope has found, and astronomers are surprised.

British researchers have tested a prototype self-eating rocket that could launch tiny satellites cheaply and without leaving any debris behind.

2023 was another eventful year for our planet, delivering broken climate records, unprecedented weather disasters and worrisome studies.
