NASA Confirms Asteroid 2024 YR4 Will Not Hit Earth, Risk Reduced to Zero
NASA has reassured the public that asteroid 2024 YR4 no longer poses any threat to Earth. Initially, the asteroid had a 1-in-32 chance of impact, making it a Level 3 risk on the Torino Scale. However, new observations have reduced the probability to zero. The asteroid will make close flybys in 2028 and 2032, providing scientists with an opportunity...

NASA Lowers Risk of Asteroid 2024 YR4 Impact
NASA has significantly lowered the risk of asteroid 2024 YR4 hitting Earth in 2032. Initial estimates placed the impact probability at 1 in 32, but updated calculations have reduced it to just 1 in 360 (0.28 percent). Experts believe the risk will continue to decline as more data is collected. Despite being the riskiest asteroid on NASA’s Sentry ...

New Seismic Data Challenges Earth's Inner Core Structure, Reveals Surprising Findings
Recent seismic data from 121 earthquakes recorded over three decades challenges previous beliefs about Earth's inner core. Researchers from the University of Southern California discovered structural changes in the core, suggesting it may not be as solid as once thought. These anomalies, observed while studying the core's slowing rotation, could of...

James Webb Telescope to Study Potentially Hazardous Asteroid 2024 YR4
Asteroid 2024 YR4, identified in December 2024, has a 2.3% chance of Earth impact in December 2032. Due to uncertainties in ground-based size estimates, JWST will conduct infrared observations in March and May to determine its true dimensions. The European Space Agency estimates its width at 55 metres, but it could be as large as 90 metres. The fin...

Chorus Waves Found Far From Earth Raise Concerns for Space Exploration
Chorus waves, energetic electromagnetic bursts resembling bird chirps, have been detected 100,000 miles from Earth, far beyond their usual range. NASA's Magnetospheric Multiscale satellites observed these waves in a flatter region of Earth's magnetosphere, contradicting prior assumptions about their formation near strong magnetic gradients. The wav...

T Tauri's Great Dimming: Astronomers Study Young Star's Potential Disappearance
The young star T Tauri, located 471 light-years from Earth, is experiencing a significant dimming event. The cause is a thick dust and gas disk blocking its light, with astronomers predicting it may disappear from view for up to a century. This event presents an opportunity for scientists to explore the chemical makeup of planet-forming regions wit...

Study Reveals Earth's Small Asteroid Likely Originated from the Moon
Asteroid 2024 PT5, discovered near Earth in 2024, is suspected to be a fragment from the Moon’s surface. Researchers found its composition matches lunar rock samples, specifically silicate-rich materials, unlike any known asteroid. Analysis from NASA’s Center for Near Earth Object Studies confirmed it is a natural object, not human-made debris,...

China’s Ceres-1 Rocket Successfully Deploys 5 Satellites for Weather and Remote Sensing
China's space industry continues to grow with the successful deployment of five satellites by the Ceres-1 rocket on 20 January. The payload included four Yunyao-1 meteorological satellites and the Jitianxing A-05 remote sensing satellite. This launch, conducted by Galactic Energy, marks a key milestone in China’s expanding commercial space sector...

Hubble Telescope Observes Young Stars HOPS 150 and HOPS 153 in Orion Nebula
The Hubble Space Telescope has captured images of two young stars, HOPS 150 and HOPS 153, in the Orion Nebula, which is located about 1,300 light-years from Earth. The binary system HOPS 150 glows in bright golden red, while HOPS 153 emits a colorful jet. These stars are still in their early stages of development, feeding from their surrounding dus...

Zombie Star’s Mysterious Spiky Filaments Baffle Astronomers in New Discovery
A zombie star remnant, Pa 30, located 6,500 light-years from Earth, is surrounded by spiky filaments that have baffled astronomers. These filaments, observed for centuries, continue to puzzle scientists, as their formation and long-term stability remain unclear. The star's explosion in 1181 was initially noted by skywatchers, but its remnant struct...

NASA's TESS Discovers Fastest Disintegrating Planet Ever Seen: What You Need to Know
NASA’s TESS has observed the closest and fastest disintegrating planet, BD+05 4868 Ab, located 141 light-years away. The planet loses a moon’s mass every million years as it is bombarded by its host star. Scientists are examining its massive dust trails, offering rare insights into the composition of terrestrial exoplanets. Researchers from MIT...

SpaceX Successfully Launches 131 Satellites on Transporter 12 Mission
SpaceX’s Transporter 12 mission, launched from Vandenberg Space Force Base, deployed 131 satellites into low Earth orbit on 14 January 2025. Among the payloads were 37 satellites from Planet Labs, including the AI-powered Pelican-2, designed for high-resolution imaging and real-time data analysis. The mission also saw the Falcon 9 booster success...

NASA's LEXI Mission Will Explore Earth’s Magnetic Shield from the Moon
NASA is preparing for the launch of the Lunar Environment Heliospheric X-ray Imager (LEXI) aboard Firefly Aerospace's Blue Ghost lander, scheduled for January 15. The mission will observe Earth’s magnetosphere, capturing X-ray images that reveal how the planet's magnetic shield reacts to solar wind. This project could improve predictions of geoma...
