The solar system contains at least 1.4 million known asteroids, primarily within the asteroid belt between Mars and Jupiter. Near Earth Objects (NEOs) pose potential collision risks. Daily, Earth encounters over ten tons of dust, while larger objects sporadically strike, causing varying impacts. Notably, the 300-meter asteroid Apophis will pass close in 2029, 2036, and 2068, with low collision risk. Nasa's DART mission showcases asteroid deflection capabilities. No known large asteroid is predicted to hit Earth in the next 1,000 years.from Science News - Times of India https://ift.tt/CNDumYo
Neuralink, led by Elon Musk, is advancing brain-computer interface technology and has moved to its second patient. The first patient, Noland Arbaugh, paralyzed from the shoulders down, successfully controlled a computer cursor with his brain. Neuralink resolved initial issues and aims to implant deeper threads for better signal detection. Musk envisions future enhancements providing superhuman abilities.
Europe's Ariane 6 rocket successfully completed its maiden flight, launching satellites from Kourou, French Guiana, and restoring Europe's autonomous space access. Despite minor issues and a trajectory deviation, the launch marked a significant achievement after a four-year development delay. This success comes amid rising competition in the space industry and Europe's recent lack of independent satellite launch capabilities.
HD 189733 b, a hot Jupiter 64 light-years away, has an atmosphere with hydrogen sulfide, giving it a rotten egg smell. The planet, orbiting its star in 2.2 days, has extreme conditions: 1,700°F temperatures, glass rain, and 5,400 mph winds. This discovery aids understanding of sulfur's role in gas giant formation.
In South Africa's Shark Week, 200 gallons of synthetic blood replicated real blood scent to attract great white sharks. Led by Dr. Greg Skomal, the experiment analyzed predatory behavior, feeding frenzy, and acute smell responses. Drones and underwater cameras captured footage, aiming to reduce shark-human interactions while advancing marine biology and conservation efforts.
