Tabby’s star drama continues
Tabby’s star, already known for its bizarre flicking and fading, dimmed throughout the four years of Kepler’s primary mission.
- Astronomy
Dark matter candidate particles are a no-show in Hitomi data
Before the Hitomi satellite broke apart, it captured data that cast further doubt on evidence of X-rays from dark matter particles in a galaxy cluster.
- Astronomy
This year’s Perseid meteor shower will be especially flashy
This year’s Perseid meteor shower could produce up to 200 meteors per hour as Earth plows through the debris trail of comet 109P/Swift-Tuttle.
- Particle Physics
Cooling stars hint at dark matter particles
Stars that cool faster than expected can be explained by hypothetical particles called axions.
- Astronomy
Magnetic fields in sun rise at 500 kilometers per hour
Magnetic fields within the sun rise up no faster than about 500 kilometers per hour, suggesting that the movement of gas is responsible for bringing these fields to the sun’s surface.
- Planetary Science
Ceres is more than just a space rock
Dawn spacecraft reveals that the dwarf planet Ceres hides a core of solid rock beneath an outer crust of minerals, salts and ices.
- Earth

Jupiter’s Great Red Spot is hot
High temperatures over Jupiter’s Great Red Spot suggest that storms pump heat into the atmosphere and warm the entire planet.
- Cosmology
Debate accelerates on universe’s expansion speed
A puzzling mismatch is plaguing two methods for measuring how fast the universe is expanding.
- Particle Physics
Latest search for dark matter comes up empty
