NASA’s Chandra X-ray Observatory and Hubble Space Telescope have captured a dramatic cosmic event: a baby exoplanet, TOI 1227 b, is being stripped of its atmosphere by powerful X-rays from its host star. Only 8 million years old and orbiting a red dwarf, this Jupiter-sized planet is losing gas at a rate equal to Earth’s entire atmosphere every 200 years. Astronomers believe the planet may eventually shrink into a barren rocky core. The discovery offers a rare, real-time glimpse into atmospheric erosion and shows how intense radiation from young stars plays a key role in shaping the long-term fate of planetary systems.

The transverse Thomson effect, a thermoelectric phenomenon theorised nearly 100 years ago, has been observed experimentally for the first time. Scientists demonstrated its unique ability to switch between heating and cooling, opening new possibilities for advanced thermal management systems.

China has launched the Tianzhou 9 cargo spacecraft carrying 7.2 tons of supplies, including upgraded spacesuits and scientific equipment, to support the Shenzhou 20 crew aboard the Tiangong space station. The mission marks China’s ninth cargo flight and highlights its ongoing investment in maintaining a long-term human presence and scientific research capability in low Earth orbit.

The GW231123 event marks the most massive black hole merger ever detected through gravitational waves, involving black holes of 100 and 140 solar masses. Observed by the LIGO-Virgo-KAGRA network, it challenges current black hole formation models with extreme mass and spin, suggesting a complex origin. Scientists believe its full implications may take years to decode.

NASA’s Parker Solar Probe has achieved a solar milestone by capturing the closest-ever images of the Sun, taken just 3.8 million miles from its surface in December 2024. These WISPR images reveal unprecedented details of the corona, solar wind, and CME collisions. Scientists say this breakthrough will improve our ability to forecast space weather and understand the Sun’s magnetic structure. The probe’s findings confirm theories about slow solar wind origins and the dynamics of solar eruptions—critical knowledge for protecting satellites, astronauts, and power grids from solar storms.
