New research examines 10 different types of global technological civilizations, how they govern themselves, how they use resources, and other factors, to determine which types may endure and which may be doomed to collapse. Simulations show that resource use plays the key role. The simulations also show which types of detectable technosignatures each may generate.
This observation from NASA’s Hubble Space Telescope, released on March 23, 2026, gives an unparalleled, detailed look at the aftermath of a supernova and how it has evolved over the telescope’s long lifetime.
Astronomers have discovered that jets from a cannibalistic black hole are erupting with the power of 10,000 suns. Continue Reading‘Dancing’ jets erupting from a cannibalistic black hole have the power of 10,000 suns
How far the Milky Way’s disk extends has long been difficult to define—it doesn’t end sharply, but fades away gradually at its outer edges. Now, for the first time, an international team of astronomers has identified the edge of the Milky Way’s star-forming disk by studying the ages of stars, revealing that the bulk of our galaxy’s star formation occurs within 40,000 light-years of the Galactic Center.
Following the recent successful test flight of NASA’s Artemis II mission around the moon, NASA rolled out the core stage, or the largest section, of the agency’s SLS (Space Launch System) rocket that will launch the crewed Artemis III mission in 2027. The stage departed from the agency’s Michoud Assembly Facility in New Orleans on Monday for shipment to NASA’s Kennedy Space Center in Florida, marking key progress on the path to the agency’s first crewed lunar landing mission to the moon under the Artemis program in two years.

So far, America has remained ahead in the new space race. But its biggest rival is making continual steps to catch up. China announced another step in that direction with the unveiling of its first ever reusable five-meter-wide composite propulsion module, announced in a press release on April 11th.
Invisible “dark matter”—what cosmologists call the mysterious glue that holds everything together—is estimated to make up more than a quarter of the universe. In chemistry, dark matter refers to the thousands of small molecules in bone and tissue that can’t be identified using mass spectrometry. They make up the vast majority of what’s known as metabolites.
