A look at the Sun’s Dusty Environment

Researchers from the Laboratory for Atmospheric and Space Physics (LASP) at the University of Colorado Boulder are diving into the dusty environment that surrounds the sun — a search that could help to reveal how planets like Earth come into being.

The pursuit comes by way of NASA’s Parker Solar Probe, a pioneering mission that has taken scientists closer to Earth’s home star than any spacecraft to date. Over two years, the probe has circled the sun six times, hitting maximum speeds of roughly 290,000 miles per hour.

In the process, the Parker team has learned a lot about the microscopic grains of dust that lie just beyond the sun’s atmosphere, said David Malas...

New Superhighway System discovered in the Solar System

Maps of the superhighway between the outer edge of the main asteroid belt at 3 AU – that is three times the distance between the Sun and thee Earth – to just beyond Uranus at 20 AU

Researchers have discovered a new superhighway network to travel through the Solar System much faster than was previously possible. Such routes can drive comets and asteroids near Jupiter to Neptune’s distance in under a decade and to 100 astronomical units in less than a century. They could be used to send spacecraft to the far reaches of our planetary system relatively fast, and to monitor and understand near-Earth objects that might collide with our planet.

In their paper, published in the Nov...

Spiders in Space: Without Gravity, Light becomes key to Orientation

Humans have taken spiders into space more than once to study the importance of gravity to their web-building. What originally began as a somewhat unsuccessful PR experiment for high school students has yielded the surprising insight that light plays a larger role in arachnid orientation than previously thought.

The spider experiment by the US space agency NASA is a lesson in the frustrating failures and happy accidents that sometimes lead to unexpected research findings. The question was relatively simple: on Earth, spiders build asymmetrical webs with the center displaced towards the upper edge...

New Sunspot Cycle could be one of the Strongest on Record, new research predicts

A visualization of the magnetic bands moving toward the equator and "terminating"
LEFT: Oppositely charged magnetic bands, represented in red and blue, march toward the equator over a 22-year period. When they meet at the equator, they annihilate one another.

RIGHT: The top animation shows the total sunspot number (black) and the contributions from the north (red) and south (blue) hemispheres. The bottom shows the location of the spots.

Scientists use an extended, 22-year solar cycle to make the forecast. In direct contradiction to the official forecast, a team of scientists led by the National Center for Atmospheric Research (NCAR) is predicting that the Sunspot Cycle that started this fall could be one of the strongest since record-keeping began.

In a new article published in Solar Physics, the research team predicts that Sunspot Cycle 25 will peak with a maximu...
