We summarize the week's scientific breakthroughs every Thursday.
- 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.
- Life
Readers wrangle with definition of ‘species’
Readers asked about the definition of "species," a new atomic clock and how a neutron star collision produces heavy elements.
