Jun 10, 2024 · But now researchers have tracked the sun’s path through the Milky Way back to a crash 2 to 3 million years ago with a dense interstellar cloud. The event was so violent it appears to have collapsed the sun’s protective bubble around the solar system and possibly even affected life on Earth.

3 days ago · Synopsis: This study maps the benefits, risks, and governance of stratospheric aerosol injection, marine cloud brightening, and a space-based sunshield through 44 focus groups in 22 countries. The findings reveal that while the global South shows more hope but diverse concerns, there is a worldwide preference for multilateral coordination and public engagement.
1 day ago · Stratospheric aerosol injection is a proposed method of solar geoengineering (or solar radiation modification) to reduce global warming. This would introduce aerosols into the stratosphere to create a cooling effect via global dimming and increased albedo, which occurs naturally from volcanic winter. [1]
1 day ago · 12,000,000,000-year-old body of water larger than anything on Earth discovered floating in space. It's about 5.8 trillion miles away. In recent decades we’ve been treated to so many incredible space discoveries, from water on Mars to peculiar structures hidden on the Moon. But perhaps one of the most bizarre and exciting discoveries made, was ...
1 day ago · The Parker Solar Probe is the first spacecraft to fly into the low solar corona. It will assess the structure and dynamics of the Sun's coronal plasma and magnetic field, the energy flow that heats the solar corona and impels the solar wind, and the mechanisms that accelerate energetic particles.
Jun 10, 2024 · Harvard Radcliffe Institute. Between 2 million and 3 million years ago, the solar system encountered turbulence on a galactic scale, colliding with a dense interstellar cloud that may have altered...
Jun 17, 2024 · NASA’s IV&V Program is currently performing IV&V for the projects listed below. With the Artemis program, NASA will land the first woman and next man on the Moon by 2024, using innovative technologies to explore more of the lunar surface than ever before.
