How blueshift might beat redshift
Even though the expanding universe makes light redder, light emitted by collapsing stars and dust clouds could appear unusually blue.
- Planetary Science
Young asteroids generated long-lasting magnetism
Pockets of iron and nickel in meteorites suggest that asteroids in the early solar system produced magnetic fields for much longer than once thought.

Speed of light not so constant after all
Even in vacuum conditions, light can move slower than its maximum speed depending on the structure of its pulses.
