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.

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.

Uranus Found Emitting Internal Heat, Reviving Hopes for Flagship NASA Mission
Astronomers have discovered that Uranus emits 12% more heat than it receives from sunlight, contradicting past data from Voyager 2. The internal warmth likely comes from leftover energy in the planet’s core, offering clues to its tilt and interior structure. This unexpected heat has intensified calls for a flagship NASA mission to Uranus. Scienti...

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...

Two Spacecraft Recreate Artificial Solar Eclipses to Observe the Sun’s Superhot Corona
Twin satellites in ESA’s Proba-3 mission have successfully recreated artificial solar eclipses from space to examine the sun’s million-degree corona. The breakthrough will allow continuous observations of the sun’s outer atmosphere, offering rare insights that natural eclipses on Earth can’t provide. The mission marks a major step in solar ...

Solar Storms Are Causing Elon Musk's Starlink Satellites To Fall From The Sky
The study revealed that geomagnetic storms caused by the Sun's eruptions increased atmospheric drag, causing satellites to re-enter faster than expected.

The Promise And Peril Of A Crewed Mars Mission
Mars mission would pursue scientific objectives like determining whether Mars ever hosted life and charting the evolution of its surface, as well as answering broader questions -- such as the history of the Sun through studying Martian soil.

Sharpest Solar Images Ever: Pink 'Raindrops' On The Sun Captured In Unprecedented Detail
The corona, the Sun's outermost layer, stretches millions of kilometres into space and is mysteriously hotter than the underlying photosphere, a phenomenon known as the 'coronal heating problem.'

Solar Eruptions Are Killing Off SpaceX's Starlink Satellites, NASA Study Reveals
The study found that solar storms cause satellites to re-enter the Earth's atmosphere faster than expected, reducing their lifespan by up to 10 days.

Scientists Predict Exact Date Life On Earth Will End: Study
A supercomputer simulation predicts that life on Earth will end in 1 billion years due to the depletion of oxygen caused by the Sun's increasing heat and brightness, ultimately rendering the planet uninhabitable.

NASA’s IMAP Spacecraft Prepares to Map the Solar System’s Edge
NASA’s Interstellar Mapping and Acceleration Probe (IMAP) has been delivered to the Astrotech facility near Kennedy Space Center for final preparations ahead of a tentatively planned launch in fall 2025. IMAP will map the heliosphere — the solar wind-driven bubble that shields our solar system from cosmic radiation. It is to orbit near Lagrange...

NASA’s Parker Solar Probe Completes Second Close Flyby of the Sun at Record Speed
NASA’s Parker Solar Probe completed a close flyby of the Sun on March 22, travelling at 692,000 kilometres per hour and approaching within 6.1 million kilometres of the solar surface. The mission, designed to study solar winds and space weather, received a healthy signal back on March 25. The team, including NASA and Johns Hopkins APL experts, ha...

Study Identifies Plasma Formation as a Pseudostreamer
ESA’s Solar Orbiter recorded a giant plasma structure extending millions of kilometres from the Sun’s surface. The footage, taken on October 12, 2022, shows a swirling motion in the solar wind, a phenomenon never observed before. Scientists identified the formation as a pseudostreamer caused by a solar flare near the Sun’s north pole. The pla...

SpaceX Falcon 9 Successfully Deploys NASA’s SPHEREx Telescope and PUNCH Probes
NASA’s SPHEREx and PUNCH missions have successfully launched aboard a SpaceX Falcon 9 rocket from Vandenberg Space Force Base in California. SPHEREx will map the entire celestial sky in 102 infrared colours, while PUNCH will study the transition of the sun’s corona into the solar wind. The two-year missions aim to deepen our understanding of th...
