Fiery rose and peach sunset skies are a unique perk of our home on Earth. But what colors appear when the sun sets on other planets in the solar system?
Scientists think a planet larger than Earth lurks in the far reaches of the solar system. Now a new telescope could confirm their belief and change solar system science
Researchers observe swirling disc around AB Aurigae star, suggesting new world is forming
Not too close, but not too far. That’s long been the rule describing how distant a planet should be from its star in order to sustain life. But a new study challenges that adage: A planet can maintain water and other liquids on its surface if it’s heated, not by starlight, but by radioactive decay, researchers calculate. That opens up the possibility for many planets—even free-floating worlds untethered to stars—to host life, they speculate.
Theoreticians in two fields defied the received wisdom that planets only orbit stars like the sun. They proposed the possibility of thousands of planets around a supermassive black hole.
Planets are basically just giant dust bunnies.
The “rogue” worlds are said to be located 3.8 billion light-years away.
We learned more about neutron stars, found more planets and said goodbye to Cassini in 2017. We end the year with a better picture of the Universe than we started it with.
The 2017 solar eclipse is nearly upon us. The path of totality will travel across 14 states, starting in Oregon and ending in South Carolina, and may trigger what some have called a “zombie apocalypse” across the contiguous U.S. as people flood the roads, skies and rails to travel to their viewing locations.
