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.
