We summarize the week's scientific breakthroughs every Thursday.
- Planetary Science
Saturn’s moon Dione has stripes like no others in the solar system
Icy moon Dione has long, thin, bright lines at its equator that run surprisingly parallel to each other for tens to hundreds of kilometers.
- Astronomy
Readers wonder about a hydrogen wall, pig lung transplants and more
Readers had questions about a glow at the edge of the solar system, pig lung transplants, the use of the word promiscuous and more.
- Astronomy
The Neil Armstrong biopic ‘First Man’ captures early spaceflight’s terror
At a time when NASA is considering how to return astronauts to the moon, ‘First Man’ is a sobering reminder of how risky the first giant leap was.
- Astronomy
The first observed wimpy supernova may have birthed a neutron star duo
Scientists have spotted a faint, fast supernova for the first time, possibly explaining how pairs of dense stellar corpses called neutron stars form.
- Astronomy
If the past is a guide, Hubble’s new trouble won’t doom the space telescope
Hubble is in safe mode, but astronomers are optimistic that the observatory will keep working.
- Animals
What bees did during the Great American Eclipse
A rare study of bees during a total solar eclipse finds that the insects buzzed around as usual — until totality.
- Planetary Science
Spiky ice spires may stud the equator of Jupiter’s moon Europa
Fields of jagged ice spires, if they exist, could affect where future spacecraft land on the Jovian moon.
- Cosmology
The universe’s continued existence implies extra dimensions are tiny
The strictest limits yet on the size of extra dimensions come from the fact that black holes haven't destroyed the universe.
- Astronomy
‘Einstein’s Shadow’ explores what it takes to snap a black hole’s picture
The new book offers a behind-the-scenes look at the Event Horizon Telescope’s attempt to image a black hole.
- Planetary Science
Saturn’s ‘ring rain’ is a surprising cocktail of chemicals
NASA’s Cassini probe got a closeup view of the material falling from Saturn’s rings into the planet. The data could help illuminate the belts’ origins.
- Astronomy
Hubble may have spotted the first known exomoon
A single sighting with the Hubble Space Telescope seems to confirm that there’s a Neptune-sized moon orbiting exoplanet Kepler 1625b.
- Astronomy
We may not have found aliens yet because we’ve barely begun looking
A new calculation says SETI searches have combed the equivalent of a hot tub out of Earth’s oceans looking for extraterrestrial intelligence in space.
