Cosmic 'dust' from supernovae hints at how stars are born

New research detected strong polarization from a young supernova remnant. It provided independent and solid evidence that the cosmic dust in the early universe was formed in supernovae. While it's true that supernovae eject ...

NASA's Perseverance studies the wild winds of Jezero Crater

During its first couple hundred days in Jezero Crater, NASA's Perseverance Mars rover saw some of the most intense dust activity ever witnessed by a mission sent to the Red Planet's surface. Not only did the rover detect ...

India awaits dust storms to fight scorching heat waves

Dust storms are unpleasant but they appear to be the only relief on the horizon for people in northern India sweltering under temperatures that have already crossed 44 degrees Celsius and are expected to climb higher as summer ...

The magnetic properties of star-forming dense cores

Magnetic fields in space are sometimes called the last piece in the puzzle of star formation. They are much harder to measure than the masses or motions of star-forming clouds, and their strength is still uncertain. If they ...

The dust and gas in protoplanetary disks

Planets form as the dust grains in a protoplanetary disk grow into pebbles and then finally into planets. Because small dust grains interact with gas (via the drag it imparts), the gas in protoplanetary disks influences the ...

Astronomers map interstellar dust grains in Milky Way

Between the stars in our Milky Way, vast amounts of tiny dust grains are floating aimlessly around. They form the building blocks of new stars and planets. But we still don't know what elements exactly are available to form ...

Planet formation may start earlier than previously thought

On their long journey to form planets, dust grains may coalesce with each other much earlier than previously thought, simulations by RIKEN astrophysicists suggest1. This may mean revisiting conventional theories of planet ...
