Astronomers have confirmed that massive stars in galaxies with low metal content often exist in binary systems, much like their counterparts in the Milky Way. An international team of seventy researchers from Belgium, the Netherlands, and Israel used the European Very Large Telescope (VLT) in Chile to monitor massive stars in the Small Magellanic Cloud. Their findings appear in Nature Astronomy.

In a new study published in Nature Astronomy, scientists have identified a clear origin for hypervelocity white dwarfs - stellar remnants racing through space at more than 2000 km/s. The research, led by Dr. Hila Glanz of the Technion - Israel Institute of Technology, used advanced three-dimensional hydrodynamic simulations to model the merger of two rare hybrid helium - carbon - oxygen wh

A NASA-sponsored team is advancing single-photon sensing Complementary Metal-Oxide-Semiconductor (CMOS) detector technology that will enable future NASA astrophysics space missions to search for life on other planets. As part of their detector maturation program, the team is characterizing sensors before, during, and after high-energy radiation exposure; developing novel readout modes to mitigat

What was the universe like in the first few hundreds of millions of years after it came into existence? How did the first stars and galaxies form? Those are questions that astronomers now have a better chance of answering, thanks to a new research program using the James Webb Space Telescope (JWST), which came online in 2022. The MINERVA program, co-led by a Tufts astronomer, will give res

The first magnetic fields that emerged after the Universe's birth may have been billions of times weaker than the pull of a refrigerator magnet, with intensities comparable to the magnetism created by neurons in the brain. Despite their weakness, researchers have found that these fields left detectable traces in the cosmic web that spans the Universe. The conclusions come from a collaborat

Pixxel has added three new Firefly satellites to orbit aboard SpaceX's NAOS Mission, doubling its commercial constellation to six. The company says this expansion delivers humanity's first daily, high-resolution hyperspectral view of Earth, enabling detailed environmental monitoring and predictive analytics at planetary scale. The Fireflies operate collectively as the most advanced commerc

NASA has launched the 2026 Human Lander Challenge (HuLC), inviting student teams across the United States to propose new solutions for advancing human landing system technologies. The initiative supports NASA's Exploration Systems Development Mission Directorate in preparing for lunar missions under the Artemis program. The competition seeks innovative ideas in known technology development

Gaia, the European Space Agency's star-mapping mission, has redrawn our understanding of stellar communities in the Milky Way. After more than a decade of observations, the spacecraft revealed that clusters of stars are not isolated but instead linked in extended chains that stretch across vast galactic distances. Launched in 2013 and operating until early 2025, Gaia has already transforme
