We summarize the week's scientific breakthroughs every Thursday.
-
- Astronomy
Star goes boom, telescopes zoom
Astronomers have spotted a supernova in the Pinwheel Galaxy, the nearest such stellar explosion in decades.
- Space
Atom & Cosmos
Planets born with off-kilter orbits, the planet formerly known as a star and more in this week's news.

- Space
Asteroid sample nails meteorite source
Dust returned from space by the Hayabusa mission shows where most space rocks landing on Earth originate.
- Astronomy
Galactic bull’s-eye came naturally
A strange cosmic object isn't the result of a galactic crash, a new study suggests.

- Space
Atom & Cosmos
Glimmers of dark matter in the Milky Way, galaxies giving birth and more in this week’s news.
- Tech
Growing need for space trash collectors
On April 2, for the fifth time in less than three years, the International Space Station fired its engines to dodge a piece of orbital debris that appeared on a collision path. Other spacecraft also regularly scoot out of the way of rocket and satellite debris. Such evasive action will be needed increasingly frequently, a new study finds.
- Planetary Science
White dwarfs gobble Earthlike treats
Astronomers have found elements in the dead stars’ atmospheres that suggest rocky planetary bodies once orbited the stars.
- Physics
Particle physicists chasing ghosts
Wispy neutrinos could one day explain why matter dominates the universe.
- Chemistry
Meteorites contain chemicals linked to life
Space rocks could have delivered DNA building blocks to Earth.
