Scientists study 3,000 supernovas and discover that dark energy may be evolving
A catalog of almost 3,000 white dwarfs that exploded as type Ia supernovas after overfeeding on companion stars indicates that dark energy is changing over time.
Sun's largest sunspots may have potential to trigger superflares
The sun is capable of great things. In massive eruptions, it repeatedly hurls particles and radiation into space. This solar bombardment can be dangerous for technical infrastruct…
