Mars Ingenuity Kicks up a Surprising Amount of Dust Every Time it Lands
There’s no way to sugarcoat it: Mars has a “dust problem.” The surface of the Red Planet is covered in particulate matter consisting of tiny bits of silica and oxidized minerals. During a Martian summer in the southern hemisphere, the planet experiences dust storms that can grow to encompass the entire planet. At other times of the year, dust devils and dusty skies are a persistent problem. This hazard has claimed robotic explorers that rely on solar panels to charge their batteries, like NASA’s Opportunity rover and the InSight lander, which ended their missions in 2018 and 2022, respectively.

This Binary System is Destined to Become a Kilonova
Kilonovae are extraordinarily rare. Astronomers think there are only about 10 of them in the Milky Way. But they’re extraordinarily powerful and produce heavy elements like uranium, thorium, and gold.
How Can We Know if We’re Looking at Habitable exo-Earths or Hellish exo-Venuses?
The differences between Earth and Venus are obvious to us. One is radiant with life and adorned with glittering seas, and the other is a scorching, glowering hellhole, its volcanic surface shrouded by thick clouds and visible only with radar. But the difference wasn’t always clear. In fact, we used to call Venus Earth’s sister planet.
Chaotic 'knot' of merging galaxy clusters captured in multiple wavelengths
Combining X-ray, radio, optical and infrared wavelengths, astronomers have imaged the messy collision of three galactic clusters leading to the formation of Abell 2256.
