Ancient Massive Stars Enriched Early Clusters and Birthed First Black Holes

The early Universe was a busy place. As the infant cosmos exanded, that epoch saw the massive first stars forming, along with protogalaxies. It turns out those extremely massive early stars were stirring up chemical changes in the first globular clusters, as well. Not only that, many of those monster stars ultimately collapsed as black holes. from Universe Today https://ift.tt/UECFnPQ via IFTTT

Hubble and Euclid Team Up To Identify A Dark Matter Galaxy

We know galaxies by their powerful illumination, generated by multitudes of stars. But some galaxies can be very dim. These are hypothesized to be dark galaxies, or dark matter galaxies. They're theoretical, and only candidates have been identified, but researchers may have confirmed the very first one. from Universe Today https://ift.tt/yR4OBtp via IFTTT

Flexible Force Fields Can Protect Our Return to the Moon

Lunar dust remains one of the biggest challenges for a long-term human presence on the Moon. Its jagged, clingy nature makes it naturally stick to everything from solar panels to the inside of human lungs. And while we have some methods of dealing with it, there is still plenty of experimentation to do here on Earth before we use any such system in the lunar environment. A new paper in Acta Astronautica from Francesco Pacelli and Alvaro Romero-Calvo of Georgia Tech and their co-authors describes two types of flexible Electrodynamic Dust Shields (EDSs) that could one day be used in such an environment. from Universe Today https://ift.tt/DUxhvrK via IFTTT

How Supermassive Black Holes Stifle Star Formation In Neighbouring Galaxies

We know that supermassive black holes can inhibit star formation in their galaxies. But new research and JWST observations show that the most luminous quasars can actually suppress star formation in neighbouring galaxies. SMBH may have played a more pronounced role in shaping the early Universe than previously thought. from Universe Today https://ift.tt/GzkoAKJ via IFTTT

Ground Teams Stop Flow of Liquid Hydrogen During Artemis II Wet Dress Rehearsal

NASA said Tuesday it will now target a March launch of its new moon rocket after running into exasperating fuel leaks during a make-or-break test a day earlier. from Universe Today https://ift.tt/DuPropG via IFTTT

An Ancient Merger Could Have Created Titan and the Debris Created Saturn's Rings

New research presents a timeline for recent (astronomically speaking) events in the Saturnian system. It shows that Titan collided with a proto-Hyperion, and the collision smoothed Titan's surface while some of the debris accreted onto a new Hyperion and also created Saturn's rings. The research can also explain some of the Saturnian system's other unusual characteristics. from Universe Today https://ift.tt/ZiOEuh1 via IFTTT

Occupy Mars? Or the Moon? Get a Reality Check on Elon Musk's Plans

SpaceX founder Elon Musk now says he wants to build a city on the moon before building a city on Mars. Is either scenario realistic? In the latest episode of the Fiction Science podcast, biologist Scott Solomon, the author of a new book titled "Becoming Martian," does a reality check on humanity's prospects for living on other worlds. from Universe Today https://ift.tt/7kh0E8w via IFTTT
