A Method for Extracting Oxygen from Extraterrestrial Soils Just Passed a Major Test

NASA’s Carbothermal Reduction Demonstration (CaRD) project completed an important step toward using local resources to support human exploration on the Moon.

Europa and Other Jovian Moons May Have Formed With Their Own Supply of Life's Building Blocks

Complex Organic Molecules (COMs) are important building blocks for life. They can form in space and be delivered to planets. But new research shows some of them can form in circumplanetary disks where moons form, boosting the prospects for life in Europa's ocean.

Into Totality: Our Complete Guide to the March 3rd Total Lunar Eclipse

If skies are clear, don’t miss one of the top astronomical events of the year this coming Tuesday, March 3rd, as the Moon passes through the Earth’s shadow in a total lunar eclipse. This will be a fine leisurely affair centered around the Pacific Ocean region, with totality lasting almost an hour in duration. For many observers worldwide, this is the last total lunar eclipse until late 2028 and mid-2029.

How giant galaxies could form just 1.4 billion years after the Big Bang

The existence of massive, elliptical galaxies in the early universe has puzzled astronomers for two decades. An international team led by Nikolaus Sulzenauer and Axel Weiß from the Max Planck Institute for Radio Astronomy (MPIfR) used data from the Atacama Large Millimeter/submillimeter Array (ALMA) to shed light on this open question of galaxy formation. They studied one of the most spectacular galaxy aggregations in great detail and published their results in the current issue of The Astrophysical Journal.

What Causes Those Snowmen in Space?

Astronomers have long debated why so many icy objects in the outer solar system look like snowmen. Michigan State University researchers now have evidence of the surprisingly simple process that could be responsible for their creation. Jackson Barnes, an MSU graduate student, has created the first simulation that reproduces the two-lobed shape naturally with gravitational collapse. His work is published in the Monthly Notices of the Royal Astronomical Society.

How Long Could Earth Microbes Live on Mars?

Searching for past or present life on Mars is the sole driving force behind every mission we send to the Red Planet, from orbiters to landers to rovers. However, there remains a concern in the scientific community of Earth-based microbes hitching a ride on Mars-bound spacecraft, also called forward contamination. The concern is potentially mistaking Earth microbes for Mars life or Earth microbes potentially influence samples of Mars life we might find. While NASA is dedicated to mitigating it as much as possible, could new methods help determine how long Earth-based microbes could survive on Mars, this alleviating concerns for forward contamination?

NASA Telescope Spots a Young Sun-Like Star Inflating Its Astrosphere

Chandra's X-ray Space Telescope, with some help from the Hubble, spotted a young Sun-like star about 120 light-years away with a powerful stellar wind. It's carving out its astrosphere, a bubble of relatively hot gas that's pushing into the surrounding, much cooler, interstellar medium. This is the same process our Sun went through 5 billion years ago when it created the heliosphere.
