Radio Telescopes Demonstrate Real-Time Space Debris Tracking

Scientists used the MIT Lincoln Laboratory radar to emit signals that bounce off orbital debris, with reflections received by the Lovell Telescope at Jodrell Bank as part of the Long Baseline Multistatic Radar (LBMR) project. This real-time method measures how far debris is and how quickly it’s moving using a single antenna, and aims to expand to multi-telescope, three‑dimensional tracking, helping monitor the growing risk from space junk in both low Earth orbit and geostationary orbit as satellite traffic rises.

NASA Eyes Moon’s Far Side for 1-km Radio Telescope to Silence Earth Noise

NASA is evaluating the Lunar Crater Radio Telescope (LCRT) on the Moon’s far side to escape Earth’s radio noise, building a ~350-meter-wide wire-mesh dish inside a natural crater with the goal of expanding to a 1-kilometer filled-aperture, robot-built telescope in the 2030s at a cost over $2 billion. Prototypes are under development at JPL, and Phase I–III funding is advancing toward a full mission. The far side’s radio-quiet environment would shield the instrument from Earth satellites (e.g., Starlink) and atmosphere, enabling observations of ultra-long wavelengths (>10 meters) that probe the universe’s dark ages and test cosmology—complementing, not replacing, Earth-based facilities.

ALMA maps the Milky Way's chaotic heart in unprecedented detail

Using the Atacama Large Millimeter/submillimeter Array (ALMA), astronomers mapped the Milky Way’s 650-light-year-wide Central Molecular Zone in unprecedented detail, revealing a complex network of dense, cold gas and molecules around Sagittarius A* to help explain how stars form in our galaxy’s extreme core.

Square Kilometre Array's Data Center Uses Dual Faraday Cages to Prevent RF Leaks

The SKA's datacenter in Western Australia, nearly complete, is protected by two Faraday cages to prevent RF leaks that could interfere with the world's largest radio telescope, which aims to explore the universe with unprecedented sensitivity. The project involves extensive antenna installation and will continue until 2029, with scientific proposals starting in 2024 and initial tests in 2027.

Scientists Uncover Origin of Mysterious Radio Burst from 1960s NASA Satellite

Astronomers using the ASKAP radio telescope in Australia detected a brief, bright radio burst originating from within 4500 km of Earth, traced to the old Relay 2 satellite, likely caused by an electrostatic discharge or space debris impact. This discovery highlights the potential for ground-based monitoring of satellite activity and the ongoing search for cosmic signals.
