White dwarf consumes icy Pluto-like planet fragment in deep space
Friday, 26 September 2025 01:03
University of Warwick astronomers have identified the chemical signature of an icy, water-rich planetary fragment being devoured by a white dwarf star. The finding offers strong evidence that volatile-rich planetesimals, capable of delivering water and the raw ingredients for life, exist in systems beyond our Solar System.
The team used ultraviolet spectroscopy from the Hubble Space Telesc Record breaking gravitational waves confirm Hawking theory and reveal giant black hole merger
Friday, 26 September 2025 01:03
For millions of years, two massive black holes circled each other until, in a split second, they merged at near light speed. The collision unleashed gravitational waves so strong and clear that researchers now have their most detailed look yet at spacetime's most violent events.
"These are waves in spacetime itself-like ripples in water-that travel at the speed of light," explained Jose Ma Exoplanets unlikely to host global oceans
Friday, 26 September 2025 01:03
Astronomers once suggested that the exoplanet K2-18b, 124 light-years away, could be an ocean world filled with life. A new study led by ETH Zurich shows that such sub-Neptune planets are far drier than previously assumed, making them poor candidates for habitable conditions.
"Water on planets is much more limited than previously believed," said ETH Zurich professor Caroline Dorn. The stud NASA modifies Dream Chaser ISS cargo contract as Sierra Space shifts to defense work

Galileo R&D tests new uplink antenna
Thursday, 25 September 2025 08:52
Galileo relies on ground-based uplink stations (ULS) to maintain accurate positioning for users worldwide. These stations transmit essential data to the satellites, including the information required to compute the satellites' orbits and clock corrections. Traditionally, such messages are sent using dish antennas. However, a new type of ground uplink antenna – a phased array antenna – was recently tested at the European Space Agency’s (ESA) site in Redu, Belgium. Developed under ESA's Horizon 2020 programme for R&D, which aims to keep Galileo up to date with the latest innovations, this innovative antenna could benefit
