Mars’ Global Dust Storms –“The Cause of Vanished Water Over Eons?”

 

Mars Global Dust Storm

 

“Global dust storms are really unusual,” said Mars Climate Sounder scientist David Kass of NASA’s Jet Propulsion Laboratory. “We really don’t have anything like this on the Earth, where the entire planet’s weather changes for several months.”

“Unrecognizable Life?” –Antarctic Proving Grounds for Extraterrestrial Exploration of Ocean Moons

BRUIE NASA Submersible

 

Arthur C. Clarke harshly warned his fellow Homo sapiens not to attempt a landing on Jupiter’s ocean moon, Europa. Ignoring his warning, NASA’s Jet Propulsion Laboratory engineers are developing BRUIE, or the Buoyant Rover for Under-Ice Exploration for underwater exploration in lunar oceans, such as those on Europa and Saturn’s moon Enceladus. It will spend the next month testing its endurance at Australia’s Casey research station in Antarctica, in preparation for a mission that could one day search for life in ocean worlds beyond Earth.

“Beyond DNA” –Researchers Probe New Models for Extraterrestrial Life

Non DNA Life

 

The discovery of the language of life, an ancient, long molecule called DNA with eight nucleotide letters suitable for storing and transmitting information, was a breakthrough in our knowledge of the range of possibilities necessary for life on Earth and beyond. Now, new studies suggest that alternatives to DNA-based life, as we know it on Earth, may be possible on other worlds.

“Glowing” –Milky Way Seen Edge On in TESS Panorama of Southern Sky

TESS Southern Sky

 

“Analysis of TESS data focuses on individual stars and planets one at a time, but I wanted to step back and highlight everything at once, really emphasizing the spectacular view TESS gives us of the entire sky,” said Ethan Kruse, a NASA Postdoctoral Program Fellow at NASA’s Goddard Space Flight Center of a new mosaic of the southern sky produced from a year of observations that includes supernova, red giant Betelgeuse, Orion Nebula, satellite galaxies, and the flare from a star ripped apart by a supermassive black hole.

“Life is Electric” –Origins of Life on Earth & Beyond

Enceladus Moon of Saturn

 

“In science fiction, there is a lot of effort put into searching for signs of life like plants, animals and organisms that look like us. But there is a higher probability that alien life will be at the microscopic level,” says Rutgers University geochemist, Nathan Yee, co-investigator at the NASA-funded ENIGMA project that’s researching how proteins, “sophisticated nanomachines,” evolved to create life on earth. “That fact is so much more interesting when you consider what the earliest lifeforms on Earth were capable of doing.”

NASA’s “TESS Mission Objects” –Targets of Alien Civilizations Probe

 

TESS First Light

 

“I do indeed suspect there are other intelligent civilizations in the galaxy – we just need to look!” said astrophysicist Andrew Siemion, principal investigator for the Breakthrough Listen program and director of the Berkeley SETI Research Center, in an email to dailygalaxy.com.
