SpaceX Shatters Launch Records with 28 Starlink Satellites, Leaving Rivals in the Dust

SpaceX launched 28 more Starlink satellites from Cape Canaveral in late September 2025, marking its 86th Starlink mission of the year. The Falcon 9 booster flew for its 22nd time and landed on a droneship in the Atlantic. Starlink’s constellation now exceeds 8,000 satellites, serving over 6 million customers in 140 countries. Astronomers warn the network is the leading source of orbital collision risk.

Weekend Science Bonanza: Breakthroughs From Space to Superbugs

Weekend Science Bonanza: Breakthroughs From Space to Superbugs

NASA confirmed its 6,000th exoplanet discovery, while astronomers observed a black hole speeding away at over 50 km/s after a merger. A weight-loss pill version of Ozempic led to 16% body weight loss in trials, and a quick EEG test detected early Alzheimer’s. Engineers nearly doubled refrigeration efficiency with nano-thin films. AI designed viruses that killed drug-resistant E. coli in lab tests.

Science Shockers: AI-Created Viruses, “Water Worlds” Debunked & More (Sept 19–20, 2025)

Researchers used AI to design the first viruses from scratch, creating bacteriophages that killed drug-resistant bacteria. Scientists solved why smoking affects ulcerative colitis and Crohn’s disease differently, linking it to mouth bacteria. New Alzheimer’s drugs modestly slowed disease in early stages. Wildfire smoke could kill 70,000 Americans annually by 2050, Stanford researchers warned.

‘God of Chaos’ Asteroid Apophis to Skim Earth in 2029 – Inside the Historic Flyby and the 3 Probes Racing to Study It

Asteroid Apophis, measuring 1,100 feet wide, will pass just 20,000 miles above Earth on April 13, 2029—closer than many satellites. Scientists confirm there is no risk of impact. NASA, ESA, and JAXA will send spacecraft to study the flyby. Up to 2 billion people in Africa and Europe may see Apophis as a bright moving point in the sky.

Solar System’s Hidden Edge: NASA’s Bold Quest to Map the Invisible Cosmic Boundary

Solar System’s Hidden Edge: NASA’s Bold Quest to Map the Invisible Cosmic Boundary

NASA’s Voyager 1 and 2 crossed the heliopause—the boundary of the Sun’s influence—at over 11 billion miles from Earth in 2012 and 2018, entering interstellar space. The heliosphere, created by the solar wind, deflects up to 90% of harmful cosmic radiation. The heliopause sits about 120 AU from the Sun. NASA’s IBEX satellite has mapped features of this boundary since 2009.
