Bennu samples reveal shifting asteroid colors as planetary scientist links spectra to surface ages
Wednesday, 27 August 2025 07:19
New results from OSIRIS-REx, NASA's first asteroid sample return mission, reveals why some gray asteroids reflect light at different wavelengths, like red or blue, more strongly. How these asteroids reflect light at red and blue wavelengths can give deeper insights into the evolution of rocky bodies in the solar system.
It also enables future research. By having a better understanding and Model brings clarity to water rich exoplanets called steam worlds
Wednesday, 27 August 2025 07:19
For astrobiologists, the search for life beyond our solar system could be likened to where one would look in a vast desert-essentially, where there's water. And it turns out that one of the most common types of exoplanet observed in planetary systems beyond ours have a size and mass that indicate a water-rich interior. They are categorized as "sub-Neptunes" because their size and mass are betwee Mapping star spots with NASA missions offers new insight into exoplanets
Wednesday, 27 August 2025 07:19
Scientists have developed a new technique to chart the star spots of distant suns using data from NASA's TESS and Kepler missions. The method, called StarryStarryProcess, builds on long-standing models of stellar spottiness and enhances how astronomers interpret transit light curves produced when planets cross their host stars.
Lead researcher Sabina Sagynbayeva of Stony Brook University e Giant star stripped to its core reveals origins of silicon and sulfur
Wednesday, 27 August 2025 07:19
Researchers led by Northwestern University and the Weizmann Institute of Science have identified a rare type of supernova that exposes the hidden inner layers of a massive star, revealing where heavy elements such as silicon and sulfur are produced.
The discovery centers on SN2021yfj, a stellar explosion detected in September 2021 by the Zwicky Transient Facility. Unlike most observed supe Real time navigation breakthrough with new algorithm OiSAM FGO
Wednesday, 27 August 2025 07:19
In the race to improve autonomous systems, researchers in China have unveiled a new algorithm that accelerates navigation while maintaining precision. Called Optimized iSAM-Factor Graph Optimization (OiSAM-FGO), the method halves processing times compared with leading benchmarks yet delivers accuracy equal to state-of-the-art solutions.
Traditional navigation tools face persistent trade-of Aurora Australis over Concordia station
Wednesday, 27 August 2025 07:00
Image:
The Aurora Australis, photographed over Concordia station in July 2025, during the ongoing solar activity maximum, the peak of the Sun's 11-year cycle.
This dazzling light show appears when charged particles from the Sun are guided by Earth’s magnetic field towards the polar regions, where they collide with gases in the upper atmosphere and create shimmering waves of colour dancing across the sky.
Concordia station, perched high on Antarctica’s Dome C plateau, is one of the most remote research outposts on Earth. On 4 May this year, the Sun set below the horizon and only returned on 10 August. During this
Webb investigates complex heart of a cosmic butterfly
Wednesday, 27 August 2025 07:00
The NASA/ESA/CSA James Webb Space Telescope has revealed new details in the core of the Butterfly Nebula, NGC 6302. From the dense, dusty torus that surrounds the star hidden at the centre of the nebula to its outflowing jets, the Webb observations reveal many new discoveries that paint a never-before-seen portrait of a dynamic and structured planetary nebula.

SpaceX answers critics with successful Starship test flight
Wednesday, 27 August 2025 03:01
SpaceX's Starship megarocket roared into the skies Tuesday on its tenth test flight, turning in a strong performance after a series of fiery failures had begun to cast doubt on its future.
Towering 403 feet (123 meters), Starship is the most powerful launch vehicle ever built and key to founder Elon Musk's vision of carrying humanity to Mars, as well as NASA's plans to return astronauts NASA targets sounding rocket's night launch for TOMEX+ Earth study
