The origin of the differing tilts in the orbits of the planets in our solar system may have been revealed through the discovery of subtle warps spotted in many planet-forming disks around young stars. A major observing program with ALMA (Atacama Large Millimeter/submillimeter Array), called exoALMA, has surveyed 15 planet-forming, or protoplanetary, disks in detail. In particular, astronomers led by …

Science & Exploration 27/08/2025 1143 views 32 likes 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 research team from the University of Basel, Switzerland, has developed a new molecule modeled on plant photosynthesis: under the influence of light, it stores two positive and two negative charges at the same time. The aim is to convert sunlight into carbon-neutral fuels. Plants use the energy of sunlight to convert CO2 into energy-rich sugar molecules. This process is …

Astronomers have spotted the brightest fast radio burst yet coming from a nearby galaxy. Observations of this phenomenon, a powerful flash of radio waves that lasts only about a millisecond, could shed light on one of the most mysterious cosmic phenomena ever studied. Fast radio bursts, or FRBs, were first discovered in 2007, but their exact sources remain unknown. Since …

MIT Professor Emeritus Rainer Weiss ’55, PhD ’62, a renowned experimental physicist and Nobel laureate whose groundbreaking work confirmed a longstanding prediction about the nature of the universe, passed away on Aug. 25. He was 92. Weiss conceived of the Laser Interferometer Gravitational-Wave Observatory (LIGO) for detecting ripples in space-time known as gravitational waves, and was later a leader of …

Teeth of a Camarasaurus, found in the Morrison Formation, USA, which were also analyzed in the research. Credit: Sauriermuseum Aathal A new method allows scientists to reconstruct carbon dioxide levels and photosynthesis from fossilized tooth enamel. A surprising new line of evidence is providing fresh insights into Earth’s ancient climate. Fossilized dinosaur teeth reveal that the atmosphere during the Mesozoic …

To study the sun, scientists use a specialized telescope called a coronagraph. This instrument mimics a solar eclipse by using a occulting disk to block out the sun’s bright light. By doing this, astronomers can study the fainter solar atmosphere, the sun’s corona, that’s hard to see when viewing the entire sun. However, recently, a coronagraph used by the National …

NASA seeks volunteers to passively track the Artemis II Orion spacecraft as the crewed mission travels to the Moon and back to Earth. The Artemis II test flight, a launch of the agency’s SLS (Space Launch System) rocket and Orion spacecraft, will send NASA astronauts Reid Wiseman, Victor Glover, and Christina Koch, along with CSA (Canadian Space Agency) astronaut Jeremy …

A child’s skeleton, found nearly a century ago in Skhul Cave on Mount Carmel in Israel, has taken on new meaning after a modern re-analysis. A fresh look at the skull and jaw, dated to roughly 140,000 years ago, suggests that the remains show a blend of Homo sapiens and Neanderthal traits. The authors say this specimen is …
