Saturn’s moon Titan is known for its methane seas, lakes, and rivers; surprisingly Earth-like in appearance yet distinctly alien at the same time. But there is also evidence for another [...]

New Study Shows How Salts Could Make Liquid Water on Mars

The Phoenix lander was the first mission to land near the Martian north pole. Was it also the first to see evidence of liquid water on Mars? Image Credit: NASA/ JPL-Caltech/University of Arizona/Texas A&M University

The search for evidence of water on Mars, past or present, has been one of the driving forces behind [...]

As the number of exoplanets discovered continues to grow exponentially, the number of potentially habitable worlds out there continues to increase as well. Astronomers have now reported finding another one of the nearest known of these kinds of planets so far, Gliese [...]

Veteran Astronauts Dave Leestma and Andy Thomas Depart NASA

Between them, Dave Leestma and Andy Thomas launched aboard no less than seven shuttle missions. This view shows the early-morning ascent of STS-77 on 19 May 1996, which marked Thomas’ first flight. Photo Credit: NASA

With seven space missions, two EVAs, and almost 200 cumulative days in orbit between them, two of NASA’s best [...]

Do Pluto and Charon Share the Same Atmosphere?

Atmospheres are, of course, a common feature of planets and even some moons. Most of the planets in our Solar System and a few moons have their own unique atmospheres, but now there may be evidence for something new: a shared atmosphere between a planet [...]
