In Scotland, NASA Scientists Search for Clues About Mars’ Past
This summer, NASA scientists headed to the Scottish Highlands to follow up on last year’s announcement of potential biosignatures on Mars and prepare for future research. The rocks and cliffs of Scotland’s Stoer formation offer a combination difficult to find on Earth: Not only did they form in environments comparable to ancient Martian lakes and rivers, but they also hold evidence of microbial life from 1.2 billion years ago, before land plants existed.

Many icy worlds in our solar system — such as Jupiter’s moon Europa or the dwarf planet Pluto — are believed to contain vast oceans of liquid water beneath thick layers of ice.

Total Lunar Eclipse! Here's When To See The "Blood Moon" In Missouri
The Moon will pass into Earth’s shadow and appear to turn red early in the morning on March 14, central time. Here’s what you need to know about the total lunar eclipse. A lunar eclipse occurs when the Sun, Earth, and Moon align so that the Moon passes into Earth’s shadow. In a total lunar eclipse, the entire Moon falls within the darkest part of Earth’s shadow, called the umbra. When the Moon is within the umbra, it appears red-orange.
Lo que necesitas saber sobre el eclipse lunar total de marzo de 2025
¿Qué es un eclipse lunar? Un eclipse lunar ocurre cuando el Sol, la Tierra y la Luna se alinean de modo que la Luna pasa por dentro de la sombra de la Tierra. En un eclipse lunar total, toda la Luna pasa dentro de la parte más oscura de la sombra de la Tierra, llamada umbra. Cuando la Luna está dentro de la umbra, se ve de un color rojo naranja. Los eclipses lunares a veces son conocidos como “lunas de sangre” debido a este fenómeno.

Earth's Moon
NASA's interactive map for observing the Moon, every day of the year. Get the latest Moon mission news on the Artemis blog. Billions of years ago, the Moon was a molten world. As it solidified, the heaviest materials (metals like iron) sank down into the Moon’s center, and the lighter materials (lower density rocks) rose towards the surface. The result is a structure a bit like a chocolate-dipped cherry – solid core, mostly solid/partly liquid mantle, and thin outer crust.
Total solar eclipse 2024: The moon's moment in the sun
On April 8, 2024, much of North America will experience a solar eclipse: a cosmic alignment of sun, moon, and Earth, in that order. The moon's shadow path will make landfall on Mexico's Pacific coast, cross the United States from Texas to Maine, and exit North America via Newfoundland, Canada, continuing into the Atlantic Ocean. Solar eclipses on Earth are a convenient coincidence.
