Tiny Asteroid 2025 TF Zooms Past Earth Undetected, Closer Than Satellites
A small asteroid named 2025 TF surprised astronomers after flying only 265 miles above Antarctica, lower than many satellites. Detected post-passage by ESA, it underscores the challenge of spotting small, fast-moving space rocks before they come close to Earth.

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 ...

ISRO To Launch 6,500 Kg Communication Satellite Built By US
After marking a humble beginning in the Indian space programme with a tiny rocket supplied by the United States, ISRO would launch a 6,500 kg communication satellite built by the US in the next couple of months, V Narayanan said.

'Minimoons': Rocks Circling Near Earth Could Be A Chunk Of The Moon
A whole population of 'minimoons' - tiny natural satellites - may be quietly circling near Earth, scientists now believe, after discovering a second Moon-origin rock drifting close to our planet.

Tiny Plasma Jets on Sun Identified as Key Drivers of Solar Wind
Observations from ESA’s Solar Orbiter have revealed that tiny plasma jets, known as picoflares, are responsible for both the fast and slow components of the solar wind. The discovery challenges previous assumptions that different mechanisms drive these solar wind types. With further research, scientists hope to refine space weather predictions, p...

NASA Launches Tiny Climate Change Satellite To Study Earth's Poles
A tiny NASA satellite was launched Saturday from New Zealand with the mission of improving climate change prediction by measuring heat escaping from Earth's poles for the first time.

NASA's Lucy Spacecraft Discovers "Mini Moon" Orbiting Asteroid Dinkinesh
With its first flyby of the asteroid Dinkinesh, Lucy discovered it is not one single asteroid, but a system of two, with a small 220m-wide satellite spinning around it.

Zimbabwe Launches First Nano-Satellite To Help Boost Agriculture
A rocket carrying the tiny satellite, dubbed ZIMSAT-1, successfully launched from Virginia in the United States alongside Uganda's first satellite as part of the Japan Aerospace Exploration Agency (JAXA) multi-nation project.

NASA, Astra to Send Another Set of Satellites in Orbit After Failure of Previous Weather Mission
NASA, along with Astra, will send another tiny storm-monitoring satellites to orbit as the companies lost their previous mission after engine failure. The earlier test had a rocket carrying two MIT-designed small satellites to measure moisture and precipitation in tropical storm systems.
