We summarize the week's scientific breakthroughs every Thursday.
- Astronomy
The X-ray glow keeps growing after the recent neutron star collision
X-rays from a neutron star collision have been getting brighter, and scientists are debating why.
- Astronomy
Stars with too much lithium may have stolen it
Some small stars have extra lithium before they grow old, suggesting they get extra amounts of the element from an external source.
- Astronomy
Mysterious high-energy particles could come from black hole jets
Three types of high-energy cosmic particles could all have the same source: black holes in galaxy clusters.
- Planetary Science
Massive dust storms are robbing Mars of its water
Mars was once lush with water. A new analysis of Martian climate data shows a mechanism that might have helped dehydrate the planet.
- Astronomy
Speed of universe’s expansion remains elusive
A discrepancy between two measures of the universe’s expansion rate suggests the presence of some unknown astronomical feature.
- Astronomy
Spaceships could use blinking dead stars to chart their way
Timing signals from five pulsars allowed scientists to pinpoint an experiment’s place in space.
- Astronomy
Trio of dead stars upholds a key part of Einstein’s theory of gravity
A cosmic test fails to topple the strong equivalence principle.
- Astronomy
Pollution is endangering the future of astronomy
Astronomers discuss multiple threats from pollution that will make it harder to observe the night sky.
- Astronomy
See a 360-degree visualization of the center of the Milky Way
A 360-degree simulation, made with data from several telescopes, shows the center of the Milky Way as seen from the galaxy’s supermassive black hole.
- Planetary Science
Shallow ice sheets discovered on Mars could aid future astronauts
Exposed water ice on steep Martian slopes suggest there’s a lot within a meter or two of the surface.
- Planetary Science
Hubble telescope ramps up search for Europa’s watery plumes
Astronomers are redoubling their efforts to confirm that the icy moon Europa spews water from its south pole.
- Astronomy
Fast radio bursts may be from a neutron star orbiting a black hole
A repeating fast radio burst has twisted waves, suggesting its home has an unusually strong magnetic field.
