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

New Organic Compounds Found in Enceladus Ice Grains

In this image captured by NASA’s Cassini spacecraft in 2007, the plumes of Enceladus are clearly visible. The moon is nearly in front of the Sun from Cassini’s viewpoint.

New kinds of organic compounds, the ingredients of amino acids, have been detected in the plumes bursting from Saturn’s moon Enceladus. The findings are the result of the ongoing deep dive into data from NASA’s Cassini mission.Powerful hydrothermal vents eject material from Enceladus’ core, which mixes with water from the

NASA lab brews up alien atmospheres here on Earth

A NASA team has recreated the atmosphere of a "hot Jupiter" exoplanet, similar to this artist's rendition of WASP-18b

Earth's pleasant, life-giving atmosphere is turning out to be somewhat of an oddity. With almost 4,000 planets so far discovered orbiting stars beyond our solar system, scientists are finding that atmospheres come in a wide range of recipes. To get a better understanding of that cosmic chemistry, a team at

Decade long study sheds light on “killer” galactic mergers

Two merging galaxies known as Arp 302, also called VV 340

Images taken by NASA's Spitzer Space Telescope are providing insight into the phenomenon of "killer" galaxies that, when they merge, shut down star formation within the new united galaxies. The collision and mixing of a pair of galaxies under the right (or wrong) conditions can disrupt the processes that allow
