Angry Sun Puts India At Risk, ISRO Warns Of Strong Radio Blackout
The Sun is angry again, unleashing a series of powerful solar flares that have triggered warnings from space agencies across the world, including India's ISRO, which is closely monitoring the situation for potential strong radio blackout conditions.

Ostriches, Stoics, Suspicions: What Back-to-Back PSLV Failure Means For ISRO
The PSLV-C62, carrying the EOS-N1 Earth-observation satellite and a cluster of commercial payloads, deviated from its planned path after "disturbances" at the end of the third stage.

Massive Sunspot Complex on the Sun Raises Risk of Strong Solar Storms
A massive sunspot complex has appeared on the Sun, covering an area comparable to the legendary Carrington Event region. Known as AR 4294-96, the active cluster features highly tangled magnetic fields that could unleash powerful solar flares and geomagnetic storms, potentially disrupting satellites, power grids, and global communications if Earth-d...

AI in Space: Why Elon Musk, Google, and Amazon Want to Make It the Next Frontier?
Major AI companies are exploring space-based data centres to cut energy and cooling costs. Google is researching solar-powered TPU satellites under Project Suncatcher, while Nvidia-backed Starcloud is preparing to launch an H100-equipped satellite powered entirely by solar energy. Leaders like Jeff Bezos and Elon Musk have also expressed interest, ...

Ursa Major III May Be a Star Cluster, Not a Dark-Matter Dwarf Galaxy
Astronomers have long thought Ursa Major III, also called UNIONS 1, was a dark-matter-packed dwarf galaxy. But new simulations suggest it may instead be a compact star cluster bound by black holes and neutron stars. Located 30,000 light-years away, Ursa Major III contains just ~60 visible stars yet shows puzzlingly high stellar velocities. The new ...

Satellite Images Show Massive Damage To Iran's Arak Nuclear Facility
Satellite pictures from Maxar Technologies, dated June 19, confirm that Israel's recent airstrike caused substantial structural damage to Iran's heavy water reactor facility at Arak, also known as Khondab, roughly 250 kilometres southwest of Tehran.

Scientists Chase Falling Satellite to Study Atmospheric Pollution from Spacecraft Reentries
In a rare airborne mission, scientists chased ESA's Cluster Salsa satellite as it reentered Earth's atmosphere. The fiery descent revealed emissions of lithium, potassium, and aluminum—chemicals that could impact the ozone layer and climate. With satellite reentries increasing, researchers aim to improve pollution models and plan further tracking...

SpaceX Launches Two SES Communication Satellites on December 17 with Successful Recovery
On December 17, SpaceX successfully launched two communication satellites for SES, marking the second mission of the day. The O3b mPOWER 7 and 8 satellites were deployed into medium Earth orbit (MEO) approximately 5,000 miles above Earth. The Falcon 9 rocket’s first stage successfully returned to Earth after launch, landing on the Just Read the I...

Satellite Images Show Lebanese Towns In Ruins After Israeli Bombing Campaign
Israel's military campaign in southern Lebanon has caused vast destruction in more than a dozen border towns and villages, reducing many of them to clusters of grey craters, according to satellite imagery provided to Reuters by Planet Labs Inc.

ESA Cluster Mission Satellite Successfully Reenters Earth After Spending 24 Years in Space
The European Space Agency (ESA) is concluding the Cluster mission, with the first of four satellites safely reentering Earth's atmosphere. This marks the end of a mission that has provided 24 years of valuable space data. In January, the satellite's orbit was adjusted to ensure its reentry would target an uninhabited area, reducing risks for humans...
