• How Christopher Nolan's 'Interstellar' turned general relativity into the bad guy

  19-07-2026 16:00 via space.com
  
  The biggest blockbusters of 2014 threw up a varied rogues' gallery of bad guys. In "Transformers: Age of Extinction", it was a reincarnated version of Optimus Prime's perma-nemesis, Megatron, while Captain America faced off against a reborn Hydra infiltrating the upper echelons of the US government in "The Winter Soldier". For Spider-Man, it was Electro, while Maleficent showed up in live-action to give Sleeping Beauty nightmares. Christopher Nolan has never been one to go with the Hollywood cro

• Artemis III astronauts will beam 4k video from Orion to Earth using SpaceX Starlink lasers

  21-07-2026 19:00 via space.com
  
  Orion is getting an upgrade on Artemis III, and the astronauts aboard are getting WiFi (sort of). NASA is partnering with SpaceX to equip the Orion spacecraft for Artemis III with a pair of Starlink mini laser terminals, designed to operate on SpaceX's existing Starlink network. The two panels will be installed on Orion's exterior, and will augment the spacecraft's existing communications systems. The added capability is expected to provide a greater data capacity from Orion to NASA's mission co

  The first trailer for "Avengers: Doomsday" dropped yesterday, and while it’s jammed full of superheroes, surprises, and our first extended look at Dr. Doom, it is missing one big thing that has been a constant in the MCU ever since "Avengers" was released and the Infinity Stone saga kicked off: outer space.Believe it or not, the MCU has been very sci-fi heavy for the past decade as the universe expanded into space with "Guardians of the Galaxy", "Captain Marvel", and the entire throughline

• Scientists may have found the 1st twin star system where both stars exploded

  21-07-2026 17:01 via space.com
  
  For the first time, scientists may have discovered a binary system—like the twin suns of the fictional planet Tatooine in "Star Wars"—where both stars exploded as supernovas, a new study finds.Although Earth may orbit around a single star, more than half of all stars are in systems where two or more suns orbit each other. "When it comes to massive stars, the percentage in multiple systems are even higher," study lead author Miltiadis Michailidis, a postdoctoral fellow at Stanford Uni

  For the first time, astronomers have reconstructed the magnetic field of an entire cluster of galaxies, from its central nucleus to its outer limits. The record-breaking achievement is the product of the deepest-ever observations of the galaxy cluster Abell 2255, located around a billion light-years away — and those observations are thanks to the European radio telescope LOFAR (Low Frequency Array). Abell 2255 has long been known for its complexity in radio waves. Its vast, diffuse radio e

• Scientists discover mystery molecule on Pluto and Saturn's moon Titan: 'We cannot say what it is'

  Separated by billions of miles and shaped by very different environments, Saturn's smoggy moon Titan and the dwarf planet Pluto have, on paper, little in common.Titan is a geologically active world cloaked in an atmosphere denser than Earth's, its landscape shaped by seas of liquid methane and vast dunes built from organic particles that rain out of its skies. Pluto, by contrast, is a frigid outpost with a tenuous atmosphere hovering above an icy, frozen surface.Yet, observations from the James

• Rocket launch costs have dropped 96% since 1960. How low can they go?

  The costs of space launch have fallen 96% in the past six decades and have the potential to plummet by nearly as much by 2040, a new study finds.However, such an improvement might get hampered by a number of challenges, such as the rise of space debris in orbit or a single company monopolizing commercial space launch, researchers added.Although previous analyses of space launch suggested that costs had dropped over time, one major problem with these prior studies was that they "considered the co

• An artificial 'Saturn's ring' of satellites could soon fill the sky, astronomers warn

  Where does James Cameron's "Aliens" rank among the other Alien movies? That depends on who you ask. Some might say it's the best, while others put it just behind the original (spoiler alert: it's the best). Regardless, there's no denying that this 1986 film shifted gears, moving the franchise from horror to horror-tinged sci-fi action and paving an alternate path for the future.As Cameron stated in an interview with Lofficier, the plan always was "to do a film that was not as scary... it's scary

  Thanks to the James Webb Space Telescope (JWST), astronomers have been given a glimpse of the mechanisms that supermassive black holes use to feed themselves. The observations could help scientists discover how supermassive black holes with masses millions, often even billions, of times that of the sun grew so fast so soon after the Big Bang.While all large galaxies have supermassive black holes at their hearts, some are slumbering giants, consuming little surrounding gas and dust, while others
