Dead NASA Satellite Relay 2 May Have Caused Mysterious 2024 Radio Burst

In June 2024, a mysterious 30-nanosecond radio burst baffled scientists — until they traced it back to a surprising source: Relay 2, a NASA satellite offline since 1967. Researchers believe the signal could have been triggered either by a micrometeorite impact or an electrostatic discharge. The discovery, detailed in a new preprint study, highlights how defunct satellites may still interact with space conditions. Experts say the incident could offer a new method for detecting electrostatic discharges from aging satellites and space debris in crowded orbits.

James Webb Telescope Captures First Direct Image of Saturn-Mass Exoplanet

NASA’s James Webb Space Telescope has reached a major milestone by capturing its first direct image of TWA 7 b, a newly discovered Saturn-mass exoplanet orbiting the young star TWA 7. Using a coronagraph to block starlight, Webb identified the planet embedded in the star’s dusty ring system. TWA 7 b is the smallest exoplanet ever imaged directly. The discovery highlights Webb’s unprecedented precision and paves the way for imaging even smaller, potentially Earth-like planets with future observatories equipped with next-generation coronagraphs and infrared imaging instruments.

Rubin Observatory Captures Distant Nebulae From Chilean Mountaintop

The Rubin Observatory has unveiled its first public images, revealing vivid views of the Lagoon and Trifid Nebulae located 4,000 light-years away. These stunning images mark the beginning of a decade-long sky survey that will capture thousands of nightly exposures, explore dark matter, and transform the way scientists—and the public—observe the dynamic universe.
