Until now, our only source of gravitational waves has been binary star systems. Researchers from Northwestern University have potentially discovered a new non-binary source of gravitational waves: the debris ‘cocoon’ that forms around a dying massive star.

Aerospace startup Polaris Raumflugzeuge has been awarded a contract by the German government to develop and fly a revolutionary Linear AeroSpike (LAS) engine that replaces the conventional rocket nozzle with curving wall-shaped plug.

Decades ago, the astronomy world was taken aback by the discovery of tall light filaments spiking out from around our galaxy's central black hole. Now more filaments have been found, only these have some significant – and puzzling – differences.

Saturn’s moon Enceladus is famous for its plumes that spray water into space. Now the James Webb Space Telescope has watched the biggest known plume so far, spanning thousands of miles, and studied how they feed a huge water “donut” around Saturn.

While two thirds of exoplanets may be a fiery, boiling wasteland, scientists believe the other third occupy a "just right" goldilocks orbit around their star, and this, much like Earth's orbit, could provide the right environmental support for life.

When ESA's Juventas CubeSat lands on Dimorphos to assess the aftermath of last year's spectacular collisions with NASA's DART spacecraft, its GRASS instrument will directly measure the asteroid's gravitational pull, which is a millionth that of the Earth.

After Virgin Orbit vanished in bankruptcy court, Virgin Galactic announced its first spaceflight in two years as the Unity 25 mission rocketed to an altitude of 54.2 miles (87.2 km) on May 25, 2023 in the skies over Spaceport America, New Mexico.

ESA is preparing to test a very cool new fold-out heat shield for protecting spacecraft on re-entry. The Pridwen won't burn away like ablative heat shields, and it'll also slow falling satellites down enough to be caught in a hover net.

Space launch company Virgin Orbit has been grounded for good after a US bankruptcy court broke it up and sold off its assets to bidders. The demise of the ambitious venture comes after a failed attempt to conduct its first mission in January.

Black holes come in two distinct types – small and supermassive. A group in the middle has long been hypothesized to exist, and now Hubble has found some strong evidence for one of these intermediate-mass black holes in a nearby star cluster.

After an initial disappointment, Jeff Bezos is back in the Moon business. NASA selected Blue Origin's Blue Moon crewed lander for the space agency's Artemis V mission to the lunar South Pole in 2029 under a firm-fixed price contract of (US)$3.4 billion.

Terran Orbit has demonstrated a record-breaking 200-gigabit orbital data link that finally allows high-bandwidth data transfer from space to Earth. It'll replace antique, low-bandwidth X-band radio technology that's currently a critical bottleneck.

A new, Earth-sized planet has been discovered only 90 light-years away. In astronomical terms, that’s right next door. Moreover, it may be capable of supporting life thanks to volcanic eruptions caused by the gravitational tug of a nearby planet.

NASA's Juno deep space probe has made its closest flyby yet of Jupiter's volatile moon Io. During its 51st orbit of the giant planet, the solar-powered robotic spacecraft came within 22,600 miles (35,500 km) of Io's volcanic surface.

Saturn has overtaken Jupiter as the planet with the most known moons in the solar system. Astronomers have announced a bumper crop of 62 new moons orbiting the ringed planet, pushing its total to well over 100.
