Scientists Finally Discover How Long a Day Lasts on Uranus
Astronomers confirm Uranus’ rotation period using internal oscillation modeling for the first time. On Uranus, a day just lasts far longer. More precise rotational time observations of the gas giant should enable scientists to plan visits to investigate it. Unlike on Mars and Earth, savage windstorms make it far more difficult to identify the rot...

JWST Captures Unseen Details of Exoplanets in HR 8799 and 51 Eridani Systems
The James Webb Space Telescope (JWST) has captured groundbreaking images of exoplanets in the HR 8799 and 51 Eridani systems. By modifying its coronagraphs, astronomers allowed more starlight to pass through, revealing clearer planetary details. The study, published in The Astrophysical Journal Letters, highlights the first successful detection of ...

NASA to Launch Three Rockets in Alaska to Study Auroral Substorms’ Impact
NASA is conducting a rocket experiment from Poker Flat Research Range in Alaska. Three rockets will launch within a three-hour window to study how auroral substorms influence the Earth's upper atmosphere. Scientists will observe whether auroras drive vertical convection or if acoustic-buoyancy waves spread their energy over a wider region. Vapour t...

Partial Solar Eclipse of March 2025: Satellite Images to Show Moon’s Shadow
A partial solar eclipse will take place on March 29, 2025, visible across parts of Europe, Africa, and North America. The event will reach its peak in Nunavik, Canada, where 94% of the sun will be covered at sunrise. From space, weather satellites like GOES-16 and Himawari will capture images of the moon’s shadow. The International Space Station ...

Solar Storm to Trigger Northern Lights in US: Visibility, Timing & Impact
A solar storm is expected to reach Earth tonight, potentially creating auroras visible as far south as New York and Idaho. The Space Weather Prediction Center (SWPC) of NOAA forecasts a G1-class geomagnetic storm, with a possibility of stronger G2 conditions. This may lead to disruptions in GPS and radio signals. The best time to witness the northe...

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...

Telescope Captures "City-Killer" Asteroid, NASA Tracking Potential Threat
A newly discovered asteroid has climbed to the top of NASA's impact risk list after fresh observations doubled its chances of striking Earth in 2032.

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...
