Sierra Space opens Power Station solar tech center in Colorado to boost defense production
Monday, 30 June 2025 10:37
Sierra Space has launched a new facility in Broomfield, Colorado, to ramp up production of its Surface Mount Technology (SMT) solar power systems, including those for national defense applications. The "Power Station," a 70,000-square-foot complex, is designed to meet growing demand for high-performance, defense-hardened solar arrays and complements Sierra Space's newly formed defense division a Asteroid 2024 YR4 poses low risk of Moon impact in 2032
Monday, 30 June 2025 10:37
Asteroid 2024 YR4 gained attention after its discovery in late December 2024, when automated systems indicated a small chance of Earth impact in 2032. This probability briefly rose to 3%, prompting a global planetary defence response. However, further observations by early 2025 eliminated the threat to Earth.
Despite this reassurance, the final recorded trajectory of 2024 YR4 left a ling Earth sized planets frequently orbit red dwarf stars study finds

Astronomers from Heidelberg University have found that Earth-like planets are especially common around low-mass stars, according to new results based on data from the CARMENES project. The international team identified four previously unknown exoplanets and revealed a strong trend: stars with less than one-sixth of the Sun's mass often host multiple small rocky planets.

Monday, 30 June 2025 10:37
Astronomers have detected a diffuse cloud of high-energy particles-called a mini halo-surrounding one of the universe's most distant known galaxy clusters, providing new insights into the energetic forces that shaped the cosmos nearly 10 billion years ago.
This mini halo is the most distant ever observed, surpassing the previous record by a factor of two. Its discovery confirms that galaxy Study challenges climate change's link to our wild winter jet stream

Dartmouth study challenges the idea that climate change is behind the erratic wintertime behavior of the polar jet stream, the massive current of Arctic air that regulates weather for much of the Northern Hemisphere.
Large waves in the jet stream observed since the 1990s have, in recent years, driven abnormally frigid temperatures and devastating winter storms deep into regions such as the Plato’s eyes meet brain

On 11 June, engineers at OHB’s facilities in Germany joined together the two main parts of ESA’s Plato mission.
They used a special crane to lift Plato’s payload module, housing its 26 ultra-sensitive cameras, into the air and carefully line it up over the service module. The supporting service module contains everything else that the spacecraft needs to function, including subsystems for power, propulsion and communication with Earth.
With millimetre-level precision, the engineers gently lowered the payload module into place. Once perfectly positioned, the team tested the electrical connections.
Finally, they securely closed a panel that connects
