Metal On Mars

A recent NASA mission has discovered that the atmosphere on Mars has many similarities to that of Earth. Metal atoms, contained in dust particles, float down from the solar system and become trapped in the atmosphere of a planet. Energetic particles, for example from the Sun, can then rip electrons from the metal atoms, forming ions. Historically, we haven’t known what happens to these ions. Depending on the specifics of the planet in … Continue reading Metal On Mars

Going with the Flow: New Evidence for Liquid Water on Mars

Surface features such as canyons and valleys on the “Red Planet” suggest an abundance of liquid water in its geological past. Water vapors on Mars were first detected in the early 60s followed by observation of water-rich ice patches decades later, but it was not until 2011 that Lujendra Ojha, a Nepali undergraduate student, spotted signs of possible water flows on our neighboring planet. While … Continue reading Going with the Flow: New Evidence for Liquid Water on Mars
