Mars Once Had Salt Lakes Similar To Earth

This NASA handout photo shows beds of sandstone inclined to the southwest toward Mount Sharp and away from the Gale Crater rim.

Mars once had salt lakes that are similar to those on Earth and has gone through wet and dry periods, according to an international team of scientists that includes a Texas A&M University College of Geosciences researcher.Marion Nachon, a postdoctoral research associate in the Department of Geology and Geophysics at

NASA’s Space Launch System gets its first rocket engine

The Artemis I SLS core stage mated with the first of four refurbished Space Shuttle-era engines

NASA has integrated the first RS-25 engine with the recently-completed core stage of its upcoming super heavy-lift Moon rocket – the Space Launch System (SLS). The engines are refurbished units that were built to power the now-defunct Space Shuttle Program, and that will now be used to return astronauts to

When exoplanets collide

Artist’s concept illustrating a catastrophic collision between two rocky exoplanets in the planetary system BD +20 307, turning both into dusty debris. Ten years ago, scientists speculated that the warm dust in this system was a result of a planet-to-planet collision. Now, SOFIA found even more warm dust, further supporting that two rocky exoplanets collided. This helps build a more complete picture of our own solar system’s history. Such a collision could be similar to the type of catastrophic event that ultimately created our moon.

A dramatic glimpse of the aftermath of a collision between two exoplanets is giving scientists a view of what can happen when planets crash into each other. A similar event in our own solar system may have formed the moon.Known as BD +20 307, this double-star system is more than

What was the first color in the universe?

This illustration shows the evolution of the Universe, from the Big Bang on the left, to modern times on the right.

The universe bathes in a sea of light, from the blue-white flickering of young stars to the deep red glow of hydrogen clouds. Beyond the colors seen by human eyes, there are flashes of X-rays and gamma rays, powerful bursts of radio, and the faint, ever-present glow of the cosmic

Universe May Be Full of Earth-like Exoplanets

Artist impression of an alien planet. Researchers say Earth-like exoplanets may be common in the universe.

There may be many Earth-like planets scattered around the universe, a study has suggested, raising the possibility that other habitable worlds are out there—and that life may have evolved on it.The first exoplanets—a planet beyond our solar system—were discovered in the 1990s. Since then, thousands have been revealed, with over
