5 cool things to know about NASA’s Lucy mission to the Trojan asteroids
NASA’s Lucy is the first spacecraft to head to the two giant clumps of space rocks that tag along in Jupiter’s orbit.
- Earth
Earth is reflecting less light. It’s not clear if that’s a trend
A decrease in Earth’s reflectance shows our planet is absorbing more solar radiation, but it’s not clear if the trend will last.
- Astronomy
A Jupiter-like planet orbiting a white dwarf hints at our solar system’s future
A new planet is the first ever discovered that is orbiting a white dwarf and resembles Jupiter in both its mass and its distance from its star.
- Astronomy
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.
- Astronomy
China’s lunar rock samples show lava flowed on the moon 2 billion years ago
The first lunar rocks returned to Earth in more than 40 years show that the moon was volcanically active later than scientists thought.
- Science & Society
How our SN 10 scientists have responded to tumultuous times
COVID-19, social justice movements and the realities of climate change have given our Scientists to Watch new perspective.
- Astronomy
When James Webb launches, it will have a bigger to-do list than 1980s researchers suspected
The James Webb Space Telescope has been in development for so long that space science has changed in the meantime.
- Astronomy
Space rocks may have bounced off baby Earth, but slammed into Venus
New simulations suggest a way to help explain dramatic differences between the sibling worlds.
- Astronomy
Satellite swarms may outshine the night sky’s natural constellations
Simulations suggest that satellite “mega-constellations” will be visible to the naked eye all night long in some locations.
- Astronomy
A supernova’s delayed reappearance could pin down how fast the universe expands
“SN Requiem” should reappear in the 2030s and help determine the universe’s expansion rate.
