Scientists Discover High-Density Rocky Planet in LHS 1903 System That Defies Conventional Formation Models
ESA’s CHEOPS mission has uncovered a surprising rocky planet at the outer edge of the LHS 1903 system. Located 116 light-years away, the discovery defies expectations that outer planets are gas giants. Scientists say the finding offers rare evidence that planets can form in gas-depleted environments, challenging current planetary formation models...

Astronomers Discover "Inside-Out" Planetary System With Rocky World Beyond Gas Planets, Challenging Formation Theories
Since the 1990s, scientists have discovered approximately 6,100 planets outside our solar system, called exoplanets.

Unique Inside-Out Planetary System Reveals Unexpected Rocky World on the Outer Edge
Astronomers have discovered a rare inside-out planetary system around LHS 1903, where a rocky planet exists beyond gas giants. Using ESA’s CHEOPS telescope, researchers found evidence that planets formed one after another in a gas-depleted environment, challenging long-standing theories about how planetary systems form and evolve across the galax...

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.

After 50 Successful Years, The European Space Agency Has Some Big Challenges Ahead
This year marks the 50th anniversary of the founding of the European Space Agency (Esa). It has launched spectacularly successful missions, but is different to other space agencies which generally represent one country.

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...

Study Finds Venus Likely Never Had Oceans, Challenging Past Theories
Recent research published in Nature Astronomy challenges past ideas about Venus, suggesting it never had oceans or conditions for life. Analysis of the planet's volcanic gases and atmospheric composition revealed that Venus’s interior is dry, ruling out the presence of liquid water. This conclusion highlights the stark contrast between Venus and ...

An Asteroid Burned Up Over California Just Hours After Being Spotted
On October 22, 2024, asteroid 2024 UQ was detected just hours before entering Earth’s atmosphere over the Pacific Ocean, near California. The ATLAS survey detected it shortly before impact, but delayed tracking data prevented immediate monitoring. The European Space Agency’s Near-Earth Object Coordination Centre later confirmed the asteroid's e...

European Space Agency Gets EUR 14.4 Billion Funding to Meet New Challenges
The 22 member states of the European Space agency pledged Thursday to boost their funding to support more missions and research projects, including a new generation of satellites to monitor climate change.
