Astronomers are baffled by a mysterious and extremely bright event in the distant Universe, nicknamed the "Tasmanian Devil", which has been observed to explode repeatedly and emit more energy than hundreds of billions of stars like our Sun. The report, published in Nature, describes a Luminous Fast Blue Optical Transient (LFBOT) monitored in a new way and shown to have unusual behaviour. L

Some exoplanets seem to be losing their atmospheres and shrinking. In a new study using NASA's retired Kepler Space Telescope, astronomers find evidence of a possible cause: The cores of these planets are pushing away their atmospheres from the inside out. Exoplanets (planets outside our solar system) come in a variety of sizes, from small, rocky planets to colossal gas giants. In the midd

Scientists are following neon signs in a search for clues to one planetary system's future and the past of another - our own solar system. Following up on a peculiar reading by NASA's previous infrared flagship observatory, the now-retired Spitzer Space Telescope, the agency's James Webb Space Telescope detected distinct traces of the element neon in the dusty disk surrounding the young Sun-like

A team of European astronomers, co-led by researchers from the Institute of Astronomy, KU Leuven, used recent observations made with the James Webb Space Telescope to study the atmosphere of the nearby exoplanet WASP-107b. Peering deep into the fluffy atmosphere of WASP-107b they discovered not only water vapour and sulfur dioxide, but even silicate sand clouds. These particles reside within a d

A Lancaster University PhD student has measured the optical depth of Saturn's rings using a new method based on how much sunlight reached the Cassini spacecraft while it was in the shadow of the rings. The optical depth is connected to the transparency of an object, and it shows how far light can travel through that object before it gets absorbed or scattered. The research, led by La

On the surface of many of the icy moons in our solar system, scientists have documented strike-slip faults, those that occur when fault walls in the ground's crust move past one another sideways, as is the case at the San Andreas fault in California. Two recently published studies led by University of Hawai'i at Manoa earth and space scientists document and reveal the mechanisms behind these geo

The remotely operated facility aboard the International Space Station has created another tool that researchers can use to probe the fundamental nature of the world around us. For the first time in space, scientists have produced a quantum gas containing two types of atoms. Accomplished with NASA's Cold Atom Laboratory aboard the International Space Station, the achievement marks another step to

In a groundbreaking move for space agriculture, Israeli agro-tech firm GreenOnyx has successfully launched its innovative Wanna Greens product into orbit. The launch, executed on November 9, 2023, aboard a SpaceX rocket bound for the International Space Station (ISS), marks the first instance of duckweed (Wolffia) being sent to space, heralding a new chapter in sustainable space food sources.

NASA's IXPE (Imaging X-ray Polarimetry Explorer) telescope has captured the first polarized X-ray imagery of the supernova remnant SN 1006. The new results expand scientists' understanding of the relationship between magnetic fields and the flow of high-energy particles from exploding stars. "Magnetic fields are extremely difficult to measure, but IXPE provides an efficient way for us to p

The first data from the InSight mission made it possible to determine the internal structure of Mars in a series of papers from the scientific team published in the summer of 2021. However, since then, the analysis of new data generated by a powerful meteorite impact that occurred on September 18 2021, questioned the first estimates of the internal structure of
