“Green Light” –New Organic Precursors to Life Detected on Saturn’s Ocean Moon Enceladus

Enceladus

 

The ongoing deep dive into data from NASA’s Cassini mission has found smaller and soluble organic building blocks on Saturn’s ocean-moon Enceladus – potential precursors for amino acids and other ingredients required for life on Earth. The findings shows that Enceladus’ ocean has reactive building blocks in abundance, and it’s another green light in the investigation of the habitability of Enceladus, said co-author Frank Postberg, about new kinds of organic compounds, the ingredients of amino acids, that have been detected in the Enceladus’ towering plumes.

“The Monster” –Andromeda Galaxy Foreshadows the Milky Way’s Fate

Andromeda Galaxy

 

“The Milky Way is on a collision course with Andromeda in about four billion years. So knowing what kind of a monster our galaxy is up against is useful in finding out the Milky Way’s ultimate fate,” said Dougal Mackey from the Australia National University’s Research School of Astronomy and Astrophysics. “Andromeda has a much bigger and more complex stellar halo than the Milky Way, which indicates that it has cannibalized many more galaxies, possibly larger ones.”

NASA’s Juno Mission to Jupiter — “Jumps the Gas Giant’s Fatal Shadow”

Jupiter's Shadow

 

“With the success of this burn, we are on track to jump the shadow on Nov. 3,” said Scott Bolton, Juno’s principal investigator from Southwest Research Institute. “Jumping over the shadow was an amazingly creative solution to what seemed like a fatal geometry. Eclipses are generally not friends of solar-powered spacecraft. Now instead of worrying about freezing to death, I am looking forward to the next science discovery that Jupiter has in store for Juno.”

“Revolutionary Implications” –Life Will Soon Be Found on Mars, NASA’s Chief Scientist

 

ExoMars

 

NASA chief scientist Jim Green, says we’re just years away from finding life on Mars, but the world is not ready for the “revolutionary” implications of the discovery as two Mars-bound rovers –from NASA and the European Space Agency (ESA)– are scheduled to launch next year and will land on the red planet by March 2021 and one or both could find evidence of life within months. The discovery will start a whole new line of thinking, says Green. “I don’t think we’re prepared for the results. I’ve been worried about that because I think we’re close to finding it and making some announcements,” he told Great Britain’s The Telegraph.

“Written in the Stars” –Galaxies Supermassive Black Holes Linked to Stellar Growth

M87 Black Hole

 

Supermassive black holes simply grow along with the stars independent of their host galaxy’s mass, the larger environment, or the cosmic epoch, says Harvard astrophysicist Angelo Ricarte.

Unveiled –“Dark Skeleton at Dawn of the Universe”

Galaxy Protocluster

 

The discovery of a ancient cluster of galaxies at the dawn of the cosmos, the most distant ever found at 13.0 billion light years away, suggests that a large structure already existed at a time when the universe was only about 800 million years old or 6 percent of its present age. Finding a cluster this far away makes finding the needle in the haystack seem an easy task, but more importantly, it reveals “the dark skeleton of the universe.”

“Bubble Worlds” –Milky Way’s Star Incubators to Colossal Nuclear Objects

 

Bubble Worlds

 

Astronomers have observed two cosmic bubble phenomenon in the Milky Way Galaxy and far beyond. The infrared image from NASA’s Spitzer Space Telescope above shows a cloud of gas and dust full of bubbles, estimated to be 10 to 30 light-years across, which are inflated by wind and radiation from hundreds of thousand of young, massive stars which form from dense clouds of gas and dust. Black veins running throughout the cloud are regions of especially dense cold dust and gas where even more new stars are likely to form.
