NASA’s Perseverance Rover Touches Safely Down on Mars
Magnetar Exhibits Bizarre Behavior, Identity Crisis
A radio-loud magnetar first observed in March 2020 suffered an apparent identity crisis, behaving like a pulsar until gradually settling into magnetar-like emissions in July. Plus, Mars’ moon Phobos, Jupiter’s moon Ganymede, and an interview with SETI Institute scientist Veselin Kostov about last week’s sextuple star system.
Scientists Narrow Potential Mass Range of Dark Matter
Dark matter is only acted upon by the force of gravity according to new research, which constrains the potential range of mass for the elusive particles. Plus, how precipitation affects the Earth’s crust, a pair of ancient asteroid impacts in Germany, NASA’s Day of Remembrance, and this week’s What’s Up.
Six-Exoplanet System in Resonance, Challenges Formation Theories
It’s a day ending in ‘y’, and planetary formation theories are once again being challenged. This time the challenge comes from a six-planet system with five planets in resonance. Plus a cloudless Jupiter, TRAPPIST-1, volcanoes, and some science of the weird.
Explore Gravitational Wave Events in Interactive Graphic
A data visualization designer has created an interactive graphic that allows us to explore all 50 gravitational wave events recorded to date, and some even have sounds! Plus, blue jet lightning and all the planetary science stories we can handle. Happy Friday!
