12+ hour, 59+ min ago  (163+ words) Essentially they want to launch multiple spacecraft and fly them in a precise, untethered formation tens to hundreds of meters apart. They then beam the light they collect to a central collecting spacecraft, allowing it to do some fancy optical…...

1+ day, 6+ hour ago  (56+ words) A small lump of rock pulled up from the Pacific Ocean seafloor in 1976 is giving scientists new clues about an ancient cosmic event. More than a hundred million years ago, two neutron stars collided. The resulting energetic kilonova sent a…...

2+ week, 13+ hour ago  (276+ words) Switch off fusion and, for ten thousand years, nothing happens. Then the Sun begins a slow, strange death: shrinking, briefly brightening, and coasting on gravitational heat for tens of millions of years. And the neutrinos give the whole thing away…...

2+ week, 13+ hour ago  (47+ words) A photon born in the Sun's core takes around 100, 000 years to fight its way to the surface, bouncing through a random walk so inefficient that the light on your face is older than human civilization. Why the Sun's surface is…...

3+ day, 1+ hour ago  (154+ words) For context, a planet's redox state is the chemical balance between oxygen and hydrogen/iron within its interior. In the context of 55 Cnc e, hydrogen is heavily favored compared to oxygen, resulting in the exoplanet's hydrogen-rich atmosphere. Artist's illustration of…...
