SpaceX launched a mission for an Indonesian telecom company tonight (Sept. 11), sending the Nusantara Lima satellite to orbit from Florida's Space Coast.
Using the James Webb Space Telescope and the Subaru Telescope in powerful tandem, scientists have discovered the first shrouded supermassive black holes at Cosmic Dawn.
New research shows that solar flares are six times hotter than thought and calls for updated sun models that could improve space weather forecasting.
Has it finally happened? Has NASA finally found biosignatures from ancient Martian life? It's too early to reach that conclusion, but the Perseverance Rover did find chemical compounds that microbes could've used as an energy-rich food. They also found minerals that could've been created by biological reactions.
TRAPPIST-1 is a red dwarf star located about 40 light years away that hosts seven Earth sized rocky planets, with at least three orbiting in the habitable zone where liquid water could potentially exist. This makes it one of the most Solar System like exoplanet systems discovered, with TRAPPIST-1e considered among the best potentially habitable exoplanets. The system's proximity and multiple potentially habitable worlds make it an ideal target for searching for technological civilisations.
Comet 3I/ATLAS is the third ISO ever detected. It was discovered by the Asteroid Terrestrial-impact Last Alert System (ATLAS) station on 1 July 2025. It's travelling through the inner Solar System at about 220,000 km/h and will make it's closest approach to the Sun in late October. Multiple telescopes have observed it, including the JWST, and will continue to observe it. Interplanetary missions like the Jupiter Icy Moons Explorer (JUICE) and Mars Express will also get a crack at it in the future. NASA's Juno may even observe it from its mission to the Jovian System.
These breathtaking photographs are the winning entries of the 2025 ZWO Astronomy Photographer of the Year Awards.
A study of the "failed star" brown dwarf known as "The Accident," conducted by the James Webb Space Telescope, may reveal a solution to an old mystery of Jupiter and Saturn.
These celestial wonders can tell us a lot about the state of the atmosphere at home on Earth as well as on other planets.
The winning bid for this screen-used prop made 'Star Wars' history last week... let's just hope the seller doesn't alter the deal.
Phases of ice that exist naturally only on frozen moons could be detected using infrared spectroscopy, according to new laboratory experiments.
The Perseverance has found compounds associated with life on Earth. But whether they indicate life on Mars awaits sample return.
The fourth satellite for the Copernicus Sentinel-1 mission, Sentinel-1D, has arrived at Félix Eboué airport, the main airport in French Guiana. From there the spacecraft, safely stored in its protective casing, will be transported to launch preparation facilities at the European Spaceport in Kourou.
The James Webb Space Telescope caught the birth of an enormous star with particle beams cutting across a stretch of interstellar space.
One of SpaceX's broadband-beaming Starlink satellites has been captured overflying a top-secret airbase in China that was photographed by a private American Earth-observation satellite.
The ZWO Astronomy Photographer of the Year Award 2025 will be streamed live online on Sept. 11.
Don't let light pollution put you off stargazing or astrophotography, I managed to see galaxies, nebulas and star clusters all in Bortle 7 and 8 class night skies.
Telepathy, good vs evil, heroes fulfilling their destiny… If the "Strange New Worlds" finale 'New Life and New Civilizations' isn't fantasy, it isn't far off.
The European Space Agency’s Plato spacecraft has safely arrived at ESTEC, ESA’s technical heart in the Netherlands. There, engineers will complete the spacecraft by connecting its solar panels and sunshield, and carry out a series of critical tests to confirm that Plato is fit for launch and ready for its planet-hunting mission in space.
Though NGC 7456 looks like a modest spiral galaxy, new Hubble and XMM-Newton observations reveal a bustling system with star-forming regions and an active core.
The search for exoplanets, planets outside our solar system, has revolutionized our understanding of planetary formation and the potential for life beyond Earth. Thousands of exoplanets have been discovered, showcasing an incredible diversity of sizes, compositions, and orbital characteristics.
