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, highlig...

Amazon's Kuiper Launches 27 Satellites, Eyes 2025 LEO Broadband Rollout
Amazon’s Project Kuiper is intensifying efforts to compete in the low Earth orbit (LEO) broadband race. With 27 satellites launched in April 2025 and plans for a 3,200-satellite constellation, Amazon has locked in dozens of launches across ULA, Blue Origin, Arianespace, and SpaceX. This move follows its successful 2023 prototypes and aligns with ...

Mysterious "Dead" Satellite Sends Powerful Signal to Earth After Decades
The radio pulse was blasted from a defunct satellite, Relay 2, which was an experimental communications satellite launched in 1964.

Seismic Mystery Solved: NASA’s SWOT Satellite Detects Greenland Mega-Tsunamis
In September 2023, a global seismic mystery puzzled scientists for nine days. New research now confirms it was caused by two mega-tsunamis triggered by landslides in East Greenland. The waves became trapped in a fjord, forming seiches that shook the Earth. Using cutting-edge data from NASA’s SWOT satellite, scientists detected these hidden waves ...

China's Most Advanced Bombers Seen On Disputed South China Sea Island
Satellite imagery shows China landed two of its most advanced bombers in the disputed Paracel islands in the South China Sea this month - a gesture that some analysts described as Beijing's latest signalling of its growing military capabilities.

NASA Satellite Detects Tree Leaf Changes as Early Volcano Eruption Warning Signal
NASA and Smithsonian scientists find that greener trees seen in satellite images may warn of upcoming volcanic eruptions. The change is linked to rising carbon dioxide emissions from magma, which trees absorb and display through greener leaves. This method could enhance early warning systems and improve public safety near active volcanoes.

NASA’s Lunar Trailblazer Moon Probe Struggles with Power and Signal Loss
NASA’s Lunar Trailblazer, launched on 26 February, has lost communication and is running low on power. The spacecraft, meant to detect water ice on the moon, has been unable to perform key trajectory corrections. Ground controllers are using the Deep Space Network and observatories to assess its position, but recovery remains uncertain. The missi...

Astronomers Spot New Cosmic Explosions 100 Times Brighter Than the Sun
Astronomers have discovered a new class of cosmic explosions, known as 'millinovas,' which are 100 times brighter than the Sun. These events, first identified in 2023, were observed in the Large and Small Magellanic Clouds, two satellite galaxies of the Milky Way. The millinovas are thought to occur when white dwarfs feed off a companion star, prod...

Russia's "Starlink Killer" Might Become A Nightmare For Ukraine, Elon Musk
In a major concern for Ukraine and its allies, as well as US billionaire Elon Musk, the Russian Military has reportedly developed an advanced system which could detect and locate signals from enemy UAVs that connect to satellite systems.

Scientists Test Mobile Tower-Based GPS Signals That Could Help Pilots in Emergency Situations
Scientists are developing a navigation system that uses mobile signals as an emergency backup for pilots when GPS systems fail. Tested with high-altitude weather balloons, the system detects signals from cell towers and satellites, providing crucial data for navigation. Although challenges remain, early results indicate its potential to revolutioni...

SWOT Satellite Observes Seismic Tsunami Event in Greenland’s Dickson Fjord
The Surface Water and Ocean Topography (SWOT) satellite, a joint mission by NASA and France’s CNES, has observed a significant tsunami event in Greenland’s Dickson Fjord. Triggered by a massive rockslide in September 2023, the tsunami lasted for nine days and generated seismic signals recorded globally. The satellite's advanced radar technology...

Elon Musk’s Starlink Satellites Could Severely Damage Ground-Based Radio Telescopes, Says Study
Elon Musk's Starlink satellites are causing significant disruption for astronomers worldwide. Scientists from the Netherlands, particularly the Netherlands Institute for Radio Astronomy (ASTRON), have reported that the growing network of Starlink satellites is interfering with radio waves used for vital space research. The satellites, designed to p...

NASA Might Have Spotted Highest Number of Sunspots in Over 20 Years
On August 8, 2024, NASA's Solar Dynamics Observatory (SDO) may have documented a record-breaking number of sunspots in a single day, marking a significant event in Solar Cycle 25. These sunspots, which are dark, cooler areas on the Sun’s surface caused by intense magnetic activity, play a crucial role in the Sun's behaviour and have a direct impa...
