SpaceTime Series 27 Episode 146
*Supernova's Potential to End the Dark Matter Search
Astronomers are eagerly awaiting a nearby supernova that could finally solve the mystery of dark matter. A new study suggests that axions, hypothetical particles, could be discovered within seconds of a supernova's gamma-ray burst. The Fermi Gamma Ray Space Telescope might detect these gamma rays, offering insights into the mass of QCD axions. However, the rarity of such supernovae and the telescope's limited field of view pose challenges. Researchers are considering launching a fleet of gamma-ray telescopes, named GALAX, to ensure comprehensive coverage.
*Magnetic Tornadoes at Jupiter's Poles
A recent study reveals that Jupiter's poles are home to magnetic tornadoes that generate Earth-sized concentrations of hydrocarbon haze. These phenomena, visible only in ultraviolet light, are linked to the planet's strong magnetic fields. The findings, based on Hubble Space Telescope images, shed light on the unique atmospheric dynamics of Jupiter, contrasting with Earth's auroral processes.
*Arrival of the World's Biggest Digital Camera at NASA
NASA's Goddard Space Flight Centre has received the Wide Field Instrument, the largest digital camera ever built, for the Nancy Grace Roman Space Telescope. This advanced camera will offer an unprecedented panoramic view of the universe, aiding in the study of dark energy, dark matter, and exoplanets. Scheduled for launch in 2027, Roman's capabilities will surpass those of current Space telescopes.
The Science Robert
A new study links prolonged sedentary behaviour with increased heart disease risk, even among active individuals. Research highlights the crucial ecological role of large sharks, threatened by overfishing and habitat loss. Palaeontologists use dinosaur faeces to trace the evolutionary rise of dinosaurs. Advances in lithium battery technology promise safer and longer-lasting power sources, potentially revolutionising energy storage.
