New observations and simulations by a team of researchers led by MPE reveal that a massive binary star near our galaxy’s center is responsible for creating a series of enigmatic gas clouds—compact gas clumps that help feed the supermassive black hole Sagittarius A*. The study is published in the journal Astronomy & Astrophysics.
Long-duration spaceflight can chip away at an astronaut’s health, prompting scientists to find new ways to make living in space easier on the body. The journey to outer space is incredibly dangerous, but crews must also face day-to-day hazards, such as exposure to cancer-causing radiation, microgravity and extreme isolation.
Eastern Africa’s Turkana Rift is both a hotbed for fossil discoveries of our earliest ancestors and a literal hotbed of volcanic activity caused by shifting tectonic plates. Now researchers have found that Earth’s underlying crust in the region has been significantly thinned, presaging Africa’s eventual breakup—and with that finding, the researchers offer a new perspective on how Turkana’s world-famous fossil record of human evolution came to be. The findings are published in Nature Communications.
NASA’s Nancy Grace Roman Space Telescope team now is targeting as soon as early September 2026 for launch, ahead of the agency’s commitment to flight no later than May 2027.
An origami-inspired reflectarray antenna developed by researchers at Institute of Science Tokyo enables CubeSats to achieve high antenna gain while fitting within the tight size constraints of small satellites. Weighing just 64 grams, it folds compactly inside a 3U CubeSat for launch and expands in space. Such designs could support higher data-rate communications, expanding the capabilities of future CubeSat missions, including deep-space and lunar exploration.
Fifteen years after Western astronomers first discovered “buckyballs” in space (soccer ball-shaped molecules that resemble a hollow sphere), they’re back with stunning images and rich data generated using the James Webb Space Telescope (JWST)—the most powerful space telescope ever built. The team led by Jan Cami, a physics and astronomy professor, first detected buckyballs using NASA’s Spitzer Space Telescope in 2010. The fantastic find came from the planetary nebula Tc 1, formed from a dying star more than 10,000 light-years away in the constellation Ara.
One of the biggest open questions in particle physics today is how the Higgs boson interacts with itself. This “self-coupling” could help explain the evolution of the early universe and the mechanism that gives mass to elementary particles. To try to shed light on this fundamental interaction, the ATLAS Collaboration has recently studied one of the “golden” decay channels of a pair of Higgs bosons, where one Higgs boson decays into two photons and the other into a pair of bottom quarks.
NASA successfully sent four astronauts around the moon for the first time in more than 50 years, setting the stage for future lunar landing missions. As the agency continues to push the bounds of space exploration, NASA’s Ames Research Center in California’s Silicon Valley provided essential support in preparing for the mission.
A team of astronomers led by Elisabeth Matthews at the Max Planck Institute for Astronomy (MPIA) has made a discovery that highlights the limits of most current models of exoplanet atmospheres: water-ice clouds on a distant Jupiter-like exoplanet called Epsilon Indi Ab.
Getting people to change their behavior is a challenging task. From the Stanford Marshmallow Experiment to the Piano Stair Experiment, scientists have been trying to understand what motivates people to alter their actions for decades. Those hurdles are especially pronounced when it comes to climate change, where overcoming the intention-action gap is a major challenge. Just because someone is concerned about climate change doesn’t mean they will change what they do on a daily basis.
NASA unveiled a new telescope on Tuesday to scan vast swaths of the universe for planets outside our solar system and probe the mysteries of dark matter and dark energy.
Astronomers from South Africa and India have analyzed archival data from the Chandra X-ray Observatory and Giant Metrewave Radio Telescope (GMRT) regarding a nearby small galaxy group known as IC 1262. Results of the new study, presented April 14 on the preprint server arXiv, provide more insights into metal enrichment of IC 1262, which could help us better understand the nature of this group.
A team of scientists using the ChemCam instrument on NASA’s Curiosity Mars rover has discovered the highest amounts of iron, manganese, and zinc ever found together in Gale Crater on Mars. Minerals with these metals were found in remarkably well-preserved ripples in rocks, indicating the high likelihood that a shallow lake existed at this location. The findings are published in the Journal of Geophysical Research: Planets.
Only about 5% of the universe is composed of normal matter that we can directly observe, while the remaining 95% is widely believed to consist of dark matter and dark energy. Paradoxically, however, the nature of these dark components remains unknown. Is this due to limitations in our observational capabilities, or does it reflect a more fundamental incompleteness in the classical laws of physics that have long underpinned our understanding of the universe?
Fluorescent probes have transformed modern biology by allowing researchers to tag and visualize individual molecules in living cells, tissues, and animals. Using these tools, researchers can watch viruses infect cells in real time, observe cellular trash collection, and track the signaling that spurs tumor growth. Now, scientists at Albert Einstein College of Medicine and the Salk Institute for Biological Studies have developed a new molecular imaging technology that illuminates proteins inside living cells and animals far more clearly than before. Described in Nature Methods, the system uses engineered fluorescent nanobodies—tiny antibody-like protein fragments—that light up only when they bind to their specific targets.
SpaceX on Tuesday announced a partnership with AI coding company Cursor and said the alliance comes with an option to buy the startup for $60 billion later this year.
Buried within the Antarctic ice are more than 5,000 light sensors that work together to detect some of the highest energy particles in the universe. These tiny particles, called neutrinos, provide insight into the extreme cosmic events that created them as well as phenomena that challenge traditional physics.
The science of memories has been pursued and studied since the days of ancient Greece and Aristotle. Today, research conducted by Dima Bolmatov, assistant professor in the Department of Physics & Astronomy at Texas Tech University, is considering how memories are stored on a cellular level.
The universe has a hidden structure, and a University of Virginia professor is mapping it in 3D, using 46 million galaxies and quasars and 19 million stars. Satya Gontcho A Gontcho, an assistant professor in the Department of Astronomy, is part of a team using the Lawrence Berkeley National Laboratory-led, Arizona-based Dark Energy Spectroscopic Instrument to conduct one of the most extensive surveys of the cosmos ever. DESI has built the largest 3D map of the universe ever created by humanity to study dark energy, one of the biggest mysteries in physics.
Following NASA’s Artemis II mission successfully splashing down on Earth, engineers started diving into detailed analysis of data to assess how key systems and subsystems on the Orion spacecraft, SLS (Space Launch System) rocket, and systems at the launch pad at the agency’s Kennedy Space Center in Florida performed. The Artemis II test flight successfully began a new era of exploration, laying the groundwork for the third Artemis mission next year, lunar surface missions, a moon base, and future missions to Mars.
