This tiny, sizzling exoplanet could be made of molten iron
A newly discovered exoplanet that whips around its star in less than eight hours is smaller than Earth, as dense as iron and hot enough to melt.

Astronomers have found the Milky Way’s first known ‘feather’
Named for the glacier that feeds India’s longest river, the Gangotri wave spans up to 13,000 light-years and bridges two of our galaxy’s spiral arms.

How massive stars in binary systems turn into carbon factories
A massive star with an orbiting partner star ejects on average twice as much carbon, an element crucial for life, into space compared with a solo star.

Distant rocky planets may have exotic chemical makeups that don’t resemble Earth’s
Elements sprinkled on white dwarf stars suggest that the mantles of faraway rocky worlds differ greatly from their counterparts in our solar system.

A stunning simulation re-creates how M87’s black hole launches plasma jets
Two jets, thousands of light-years long, are re-created in a computer simulation, which suggests that M87’s black hole must be spinning rapidly.

Neutron star collisions probably make more gold than other cosmic smashups
Smashups of two neutron stars produce more heavy elements than when a black hole swallows a neutron star, calculations suggest.

A rush to watch a supernova exposed its last gasp before exploding
By studying the final years of stars, scientists hope to find clues to help them recognize when other stars are about to blow.

The fastest-spinning white dwarf ever seen rotates once every 25 seconds
A white dwarf star that spins every 25 seconds owes its record-breaking rotation rate to a companion star dumping gas onto it.
