NASA warns of powerful solar storm and blackouts. When it is likely to hit earth
A significant solar flare has been released by the Sun, peaking at X1.4, according to NASA Solar flares are intense bursts of radiation but cannot harm humans directly, impacting GPS and communication signals. The associated coronal mass ejection from Region 3697 is expected to enhance Earth¡¯s magnetic field, leading to potential geomagnetic storms.

What is in-flight turbulence, and when does it become dangerous for passengers and crew?
A British man's death and numerous injuries on a Singapore Airlines flight due to severe turbulence highlight the dangers of unstable air. While turbulence-related fatalities are rare, injuries are more common, especially among flight attendants. Clear-air turbulence, often near jet streams, is particularly dangerous as it occurs with no visible warning. Climate change may increase turbulence, but airlines have safety measures in place. Experts advise passengers to wear seat belts, the best defense against turbulence-related injuries.
Why Venus is dry, new study explains

Dubai Floods: Is artificial rain behind UAE's rare torrential weather?
Dubai Floods: Dubai experienced rare torrential rain, causing widespread flooding and raising concerns about climate change's impact on extreme weather. The UAE's cloud seeding program, initiated in 1982, aims to enhance rainfall by stimulating cloud condensation. Managed by the NCM, the program uses natural salts as seeding agents, avoiding environmental harm. The UAEREP analyzes atmospheric conditions and pollutants to optimize cloud seeding. Despite environmental concerns, the UAE's innovative approach demonstrates its commitment to sustainable solutions amid escalating climate challenges.

Astronomers discover heaviest element yet detected in an exoplanet atmosphere
WASP-76 b and WASP-121 b are no ordinary exoplanets. Both are known as ultra-hot Jupiters as they are comparable in size to Jupiter whilst having extremely high surface temperatures soaring above 1000¡ãC. This gives these planets rather exotic features; in WASP-76 b, for example, astronomers suspect it rains iron.
