NASA Early Earth: "Violent Solar Flares Provided Energy to Create RNA and DNA Molecules"

“Back then, Earth received only about 70 percent of the energy from the sun than it does today,” said Vladimir Airapetian, a solar scientist at NASA’s Goddard Space Flight Center. “That means Earth should have been an icy ball. Instead, geological evidence says it was a warm globe with liquid water. We call this the Faint Young Sun Paradox. Our new research shows that solar storms could have been central to warming Earth.”

NASA: James Webb Science Gear Installed --"Will Detect Solar Systems Capable of Supporting Life"

Hubble's successor, the James Webb Space Telescope (JWST), "represents the hopes and ambitions of the 10,000 astronomers who have already used the Hubble," said John Mather, Nobel laureate, astrophysicist at NASA's Goddard Space Flight Center, and the senior project scientist for the new JWST observatory in a recent interview. "It is tremendously more powerful than the Hubble, in a new wavelength range. I'm pretty confident there will be surprises out there, things that will be worth all this work."

NASA New Flash: "All Galaxies Including Milky Way are Embedded Within a Vast Sphere of Black Holes"

Dark matter is a mysterious substance composing most of the material universe, now widely thought to be some form of massive exotic particle. An intriguing alternative view is that dark matter is made of black holes formed during the first second of our universe's existence, known as primordial black holes. Now a scientist at NASA's Goddard Space Flight Center in Greenbelt, Maryland, suggests that this interpretation aligns with our knowledge of cosmic infrared and X-ray background glows and may explain the unexpectedly high masses of merging black holes detected last year.

Hubble: "Astronomers Discover Seeds that Grew Into Monster Black Holes Soon After Big Bang"

“Our discovery, if confirmed, would explain how these monster black holes were born,” said Fabio Pacucci, lead author of the study, of Scuola Normale Superiore in Pisa, Italy. "This new result helps to explain why we see supermassive black holes less than one billion years after the Big Bang."

“The ability to measure the top quark mass precisely is fortuitous because it, together with the Higgs boson mass, tells us whether the universe is stable or not,” said Robert Kehoe, a physicist at Southern Methodist University. “That has emerged as one of today’s most important questions.”

The Early Mars: New Evidence Points to Conditions Conducive to Emergence of Life

The fate of water on Mars has been energetically debated by scientists because the planet is currently dry and cold, in contrast to the widespread fluvial features that etch much of its surface. Scientists believe that if water did once flow on the surface of Mars, the planet’s bedrock should be full of carbonates and clays, which would be evidence that Mars once hosted habitable environments with liquid water. Researchers have struggled to find physical evidence for carbonate-rich bedrock, which may have formed when carbon dioxide in the planet’s early atmosphere was trapped in ancient surface waters. They have focused their search on Mars’ Huygens basin in the Southern Highlands (above).

The Faintest Galaxy of the Early-Universe Discovered --"Could Solve One of the Biggest Mysteries in Astronomy"

An international team of scientists, including two professors and three graduate students from UCLA, has detected and confirmed the faintest early-universe galaxy ever, behind a galaxy cluster known as MACS2129.4-0741, which could help explain how 'cosmic dark ages' ended. Using the W. M. Keck Observatory on the summit on Mauna Kea in Hawaii, the researchers detected the galaxy as it was 13 billion years ago. The results were published in the Astrophysical Journal Letters.

Dark Matter Galaxies Detected --"How is It Possible for Galaxies So Diffuse and Dark to Exist"

Galaxies, in all their forms from spirals to ellipticals from giants to dwarfs have been widely studied over the past Century. To the surprise of the scientific community last year a new type of galaxy was discovered, residing in a galactic megalopolis known as the Coma Cluster, some 300 million light years away from Earth. Even though they are very numerous, these ultradiffuse galaxies have not been noticed until now because they are very fain. Their stars as spread over a very large area, which makes it particularly difficult to distinguish them from the sky background.

"Cosmic Leapfrog" --Will China's Enormous 'Super Collider' Reveal Unknowns of the Universe? (A 'Galaxy' Insight)

“So far the Standard Model seems to explain matter, but we know there has to be something beyond the Standard Model,” said Denise Caldwell, director of the Physics Division of the National Science Foundation. “This potential new physics can only be uncovered with more data that will come with the next LHC run.” The Standard Model contains no explanation of gravity, which is one of the four fundamental forces in the universe. It also does not explain astronomical observations of dark matter, a type of matter that interacts with our visible universe only through gravity, nor does it explain why matter prevailed over antimatter during the formation of the early universe. The small mass of the Higgs boson also suggests that matter is fundamentally unstable.

Far-Future of Space Travel? The Planet's First Experimental Wormhole Created (Monday's Most Popular)

"If you have a wormhole, then you can turn them into time machines for going backward in time," says Caltech's Kip Thorne. "Wormholes" are cosmic tunnels that can connect two distant regions of the universe, or even to a parallel universe, and have been popularised by the dissemination of theoretical physics and by works of science fiction like Stargate, Star Trek or, more recently, Interstellar.
