We summarize the week's scientific breakthroughs every Thursday.
- Astronomy
Watch the oldest surviving film of a total solar eclipse
A short film of the 1900 total solar eclipse was restored by conservation experts and is now available to view online.
- Astronomy
Questions about solar storms, slingshot spiders and more reader feedback
Readers had questions about solar storms, a robotic gripper, slingshot spiders and more.
- Planetary Science
Icy volcanoes on Pluto may have spewed organic-rich water
Planetary scientists found ammonia-rich ice near cracks on Pluto, suggesting the dwarf planet had recent icy volcanoes.
- Physics
100 years ago, an eclipse proved Einstein right. Today, black holes do too — for now
In 1919, an eclipse affirmed Einstein’s famous general theory of relativity. Now scientists hope to use black holes to poke holes in that idea.
- Physics
Big black holes can settle in the outskirts of small galaxies
Astronomers have found dozens of surprisingly massive black holes far from the centers of their host dwarf galaxies.
- Planetary Science
China’s lunar rover may have found minerals from the moon’s mantle
The Chang’e-4 mission spotted material on the lunar surface that appears to contain bits originating from the moon’s interior.
- Planetary Science
Apollo-era moonquakes reveal that the moon may be tectonically active
Moonquakes recorded decades ago suggest the moon is tectonically active. Knowing more about that activity could help scientists identify where to land future spacecraft.
- Ecosystems
Readers were curious about green icebergs, aliens and more
Readers had questions and comments about icebergs and climate change, CBD and NASA’s search for E.T.
- Astronomy
Dying stars called collapsars may forge much of the universe’s gold
Spinning stars that collapse into black holes could help explain the origins of heavy elements such as gold and silver.
- Physics
What a nearby kilonova would look like
Physicists imagined what we’d see in the sky if two neutron stars collided just 1,000 light-years from Earth.
- Physics
LIGO is on the lookout for these 8 sources of gravitational waves
Gravitational wave hunters are on a cosmic scavenger hunt. Here’s what they’re hoping to find.
- Physics
LIGO and Virgo made 5 likely gravitational wave detections in a month
It took decades to find the first gravitational wave event, and now they’re a weekly occurrence.
