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

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

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. These results stem

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

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

Sceye, the U.S.-based aerospace firm developing High-Altitude Platform Systems (HAPS), has announced a strategic investment from SoftBank Corp. (TOKYO:9434) as part of its Series C funding round. The agreement includes both funding and the purchase of a pre-commercial HAPS demonstration flight scheduled for 2026 in Japan. This collaboration underscores SoftBank's continued commitment to ad

Rocket Lab Corporation (Nasdaq: RKLB) has successfully launched its 68th Electron mission, marking a new record for the company with two missions from the same site in under 48 hours. The latest launch, named 'Symphony In The Stars,' lifted off from Launch Complex 1 in Mahia, New Zealand on June 28 at 7:08 p.m. local time (07:08 UTC). The mission carried a single satellite for a confidenti

The Mars Reconnaissance Orbiter is testing a series of large spacecraft rolls that will help it hunt for water. After nearly 20 years of operations, NASA's Mars Reconnaissance Orbiter (MRO) is on a roll, performing a new maneuver to squeeze even more science out of the busy spacecraft as it circles the Red Planet. Engineers have essentially taught the probe to roll over so that it's nearly

The earliest light in the universe has been traveling across space since just after the Big Bang. Known as the cosmic microwave background, it is imperceptible to the human eye. But if scientists can capture it, using some of the most sensitive detectors ever made, it can tell us about how our universe formed and evolved over time. Researchers have released unprecedentedly sensitive measur

ICEYE and the Finnish Ministry of Defense have signed a Letter of Intent that will allow Finland's Defense Forces to acquire ICEYE Synthetic Aperture Radar (SAR) satellites. This partnership is intended to enhance the country's space-based intelligence and surveillance capabilities. The agreement includes a preliminary delivery schedule and outlines the technical systems required to create
