Hubble Delivers Best View Yet of Rare Interstellar Comet 3I/ATLAS Racing Through Solar System
Hubble has captured its sharpest image of 3I/ATLAS, a rare interstellar comet speeding through the solar system at 130,000 mph. The view reveals a dust-filled coma, a faint tail, and activity similar to native comets. Astronomers aim to study its composition before it vanishes forever, offering insight into objects formed around other stars.

Sun Erupts with Triple Solar Flares After Weeks of Silence
After a 22-day period of solar calm, the Sun unleashed three M-class solar flares on August 3–4, 2025, all originating from active sunspot region AR 4168. These moderate flares released intense radiation, capable of briefly disrupting high-frequency radio signals and potentially sparking auroras at high latitudes. Scientists also detected likel...

Indian Scientists Unravel the Mystery Behind Rare Aurora Over Ladakh
A team of Indian astronomers has successfully explained the rare aurora seen over Ladakh, caused by intense solar activity and CME collisions. The event, captured in May 2024, was traced using global data and advanced solar models, offering new insights into space weather forecasting and solar storm impacts on Earth.

Colossal Solar Filament Eruption Sculpts 250,000-Mile 'Canyon of Fire' on the Sun’s Surface
A massive July 15 filament eruption from the sun’s limb carved a 250,000‑mile‑long plasma canyon captured by NASA’s SDO. The spectacular rift, formed as magnetic fields realigned, featured 12,400‑mile‑high plasma walls. Although the eruption launched a coronal mass ejection into space, SOHO and GOES‑19 imagery confirm it’s heading a...

ESO Captures Clear Images of Interstellar Comet 3I/ATLAS Using VLT
The European Southern Observatory’s Very Large Telescope has captured the clearest images so far of comet 3I/ATLAS, an interstellar visitor first spotted on July 1, 2025. Identified by its hyperbolic orbit, the comet is only the third interstellar object recorded passing through our solar system. The VLT’s deep image and timelapse confirm it is...

Astronomers Discover 3I/ATLAS, Largest Interstellar Comet Yet Detected
Astronomers have discovered 3I/ATLAS, the third known interstellar comet to pass through our solar system. Detected by the ATLAS telescope in Chile, it’s racing inward at 150,000 mph and will swing closest to the Sun in October. Estimated to be 10–20 kilometers across, it is likely the largest interstellar object observed so far. Signs of comet...

Massive X-Class Solar Flare Erupts, Causing Widespread Pacific Radio Blackouts
A powerful X1.9-class solar flare from sunspot 4114 erupted on June 19, disrupting shortwave radio signals across the Pacific, including Hawaii. While it caused significant atmospheric ionisation, no coronal mass ejection (CME) followed. The event highlights rising solar activity and hints at more eruptions ahead, potentially impacting communicatio...

Scientists Spotted the Largest Comet Lying in the Solar System’s Outskirts with Outbursting Gases
NASA confirms comet C/2014 UN271, the largest known from the Oort Cloud, is chemically active. Detected by ALMA from far beyond Neptune, the comet’s carbon monoxide jets offer rare insights into icy body chemistry and early solar system conditions.

Aurora Alert! Northern Lights May Be Visible as Far South as New York on June 14
A moderate G2 geomagnetic storm on June 14 could push auroras as far south as New York and Idaho, triggered by solar wind from a coronal hole. NOAA forecasts peak geomagnetic activity with a Kp index of 5.67. While increased daylight may limit visibility, skywatchers are advised to look out for northern lights during early morning hours.

Video: Solar Orbiter Spacecraft Reveals Sun's South Pole For The First Time
The robotic Solar Orbiter spacecraft has obtained the first images ever taken of our sun's two poles as scientists seek a deeper understanding of Earth's host star, including its magnetic field, its 11-year cycle of activity and the solar wind.

NASA Study Confirms Solar Storms Prematurely Ended Starlink Satellite's Lifespan
A recent study, backed by NASA, reveals that solar storms are causing Starlink satellites to reenter Earth's atmosphere much faster than anticipated. Analysing data from hundreds of Starlink deorbit events between 2020 and 2024, researchers found that heightened geomagnetic activity drastically increases atmospheric drag, leading to quicker orbital...

MAVEN Reveals How Mars Lost Its Atmosphere and Became a Barren World
NASA’s MAVEN spacecraft has provided the first direct evidence of "sputtering"—a powerful atmospheric escape process where solar wind particles blast atoms off Mars. The newly published study confirms that this process played a major role in the Red Planet’s transformation from a once-wet, habitable world to its current barren state. Argon ga...
