SpaceNeutrinos could reveal how fast radio bursts are launched
Highly magnetized stellar corpses called magnetars may be the source of two different cosmic enigmas: fast radio bursts and high-energy neutrinos.

Planetary ScienceEarth’s building blocks may have had far more water than previously thought
Space rocks and dust from the inner solar system could have delivered enough water to account for all the H2O in the planet’s mantle.

AstronomyCheck out the first-ever map of the solar corona’s magnetic field
Solar physicists watched waves in the sun’s corona to map the whole corona’s magnetic field. Future observers could use the same technique to predict solar eruptions.

AstronomyIn a first, astronomers spotted a space rock turning into a comet
Scientists have caught a space rock in the act of shifting from a Kuiper Belt object to a comet. That process won’t be complete until 2063.

SpaceParadoxically, white dwarf stars shrink as they gain mass
Observations of thousands of white dwarf stars have confirmed a decades-old theory about the relationship between their masses and sizes.

CosmologyScientists can’t agree on how clumpy the universe is
A measurement of 21 million galaxies finds a level of clumpiness that disagrees with estimates based on the oldest light in the universe.
