Elon Musk's SpaceX has made awe-inspiring achievements since its founding more than two decades ago and has big ideas—colonies on Mars, orbital AI data centers, rapidly reusable rockets—for the future.
Elon Musk's SpaceX was set to begin trading on the Nasdaq exchange Friday, with the biggest initial public offering in history expected to make the polarizing entrepreneur the world's first trillionaire.
Using the Subaru Telescope, astronomers have conducted follow-up observations of a recently discovered exoplanet known as TOI-1883 b. Results of the new observations, published June 5 on the arXiv preprint server, indicate that TOI-1883 b is a low-density super-Neptune.
Once charted as a 'guest star' in ancient China, dreaded as a harbinger of ill omens in medieval Europe, and preserved in the narratives and artworks of Indigenous cultures, these cosmic spectacles are now known as core-collapse supernovae.
The United States government's recent release of hundreds of previously classified unidentified anomalous phenomena (UAPs) cases spanning the 1940s to the present, along with the new Steven Spielberg movie, "Disclosure Day," about extraterrestrial life, has fueled the idea that aliens are visiting Earth.
Elon Musk's SpaceX began its first day as a public company on Wall Street on Friday after the biggest initial public offering in history, with the polarizing entrepreneur promising he will take humanity to Mars.
Looking somewhat like a swarm of bees returning to their hive, this NASA Hubble Space Telescope image features the galaxy cluster MACS0329-0211. Galaxy clusters like MACS0329-0211 are important signposts in the story of how the structure of the universe evolved, and are the ultimate telescopic lenses, placing gravitationally lensed galaxies from the earliest stages of the universe into our view.
SpaceX launched a Falcon 9 rocket loaded with Starlink satellites Friday less than an hour before Elon Musk's company was set to lift off for what would be the largest IPO in Wall Street history.
This March 20, 2026, image of Messier 64, or the Black Eye Galaxy, is a composite view from NASA's Hubble Space Telescope and James Webb Space Telescope. It shows Messier 64 captured at near- and mid-infrared wavelengths by Webb, while Hubble's image shows the galaxy in ultraviolet, visible, and near-infrared light.
Astronomers may have uncovered new details about one of the Milky Way's most important ancient collisions. Using data from the Dark Energy Spectroscopic Instrument (DESI) and a new clustering algorithm, researchers have found evidence suggesting the famous Gaia-Sausage/Enceladus structure (GSE) has a far more complicated origin than previously thought.
To truly understand what an asteroid is made of, we need to send a probe to it. Remote sensing from ground-based telescopes, or even orbiting observatories, can only do so much. A new white paper submitted to the U.K. Space Agency's 2035 Space Frontiers program (available on the arXiv preprint server) pitches just such a mission architecture. Called the REndezvous Mission for Orbital Reconstruction of Asteroids (REMORA), the plan calls for a swarm of autonomous CubeSats to tag, track and characterize multiple near-Earth asteroids.
More than 20 years after its founding, SpaceX made history Friday with its record-high stock market debut, crowning a unique journey marked by dazzling successes but also catastrophic failures and unfulfilled promises.
Using NASA's Chandra X-ray spacecraft, astronomers have performed deep X-ray observations of a galactic globular cluster known as NGC 6540. The new observational campaign, described June 1 on the preprint server arXiv, focused on disentangling the nature of a peculiar X-ray flare emitted by the cluster about two decades ago.
Sarah Pappert is a Ph.D. candidate in astrophysics at the TUM School of Natural Sciences and conducts research at the Max Planck Institute for Extraterrestrial Physics. She is supervised by Prof. Dr. Reinhard Genzel and Prof. Dr. Frank Eisenhauer, who holds a TUM Distinguished Affiliated Professorship at the TUM School of Natural Sciences. Her research focuses on supermassive black holes and the development of astronomical instruments for the Extremely Large Telescope in Chile. In addition to her research, she is actively involved in science communication and is committed to encouraging girls and young women to pursue studies and careers in STEM.
Physicists led by the University of Iowa have documented in the finest detail to date how energy from the sun interacts with Earth's magnetic field, which could yield greater insight into solar effects on Earth that drive space weather.
