"Seeing Through the Big Bang Into Another Universe" --LIGO Gravitational Wave Discovery May Confirm an Outrageous 'New' Cosmology (WATCH Weekend 'Galaxy' Stream)

"Your theory is crazy, but it's not crazy enough to be true," said the great Danish physicist Niels Bohr. Enter Sir Roger Penrose. Correlated noise in the two LIGO gravitational-wave detectors may provide evidence that the universe is governed by...        

This Week's "Planet Earth Report" --Stephen Hawking: 'AI is a New Form of Life' to the Black Swan Satellite Theory

This week's link to 10 headline stories from around the world on the threats, opportunities, and dangers facing our fragile planet --along with an occasional dash of humor, popular culture, and an intriguing conspiracy theory or two. Stephen Hawking --Artificial...        

ESO's Journey to the Most Remote Galaxy in the Observable Universe (WATCH Today's 'Galaxy' Stream)

An international team of astronomers using the European Southern Observatory (ESO) Very Large Telescope high in the mountains of Chile measured the distance to the most remote galaxy so far. This is the first time that astronomers have been able...        

Jupiter and Saturn's Rapid Early Growth Was the Source of Most of the Water on Earth

"First of all, it's important to leave aside the idea that Earth received all its water via the impacts of comets from very distant regions. These 'deliveries' also occurred, but their contributions came later and were far less significant in...        

"GJ 273b, Come In Please!" --Astronomers Debate Wisdom of Messaging Potentially Advanced Alien Civilizations (WATCH Video)

This October, scientists and artists beamed a message to GJ 273, a red dwarf also known as Luyten's star that lies 12.36 light-years from Earth and hosts two known planets, one of which, GJ 273b, may be capable of supporting...     ...

NASA Scientists Debate Alien Planet 55 Cancri e --"Does It Have an Atmosphere Like Earth & Venus?"

"If there is lava on this planet, it would need to cover the entire surface," said Renyu Hu, astronomer at NASA's Jet Propulsion Laboratory, and co-author of a study published in The Astronomical Journal. "But the lava would be hidden...        

"Hacking Einstein" --Viewing the Universe as the Output of a 13.7-Billion Year Computation (WATCH Video)

Can a close look at the universe give us solutions to problems too difficult for a computer - even if we built a computer larger than a planet? Physicist Stephen Jordan reflects on this question in a new video by...        

Scientists Solve 22 Million-Year-Old Climate Puzzle --"Paleoclimate Events Can Predict Earth's Future"

The modern link between high carbon dioxide levels and climate change didn't appear to hold true for a time interval about 22 million years ago; but now a new study has found the link does indeed exist, settling a prehistoric...    ...

The Alien Observatory: "NASA is Using Earth as an Exoplanet in Search for Alien Life"

"An alien would spot three planets in our solar system in the habitable zone [Earth, Mars and Venus]," says research scientist Andrew Rushby, of NASA Ames Research Center, in Moffett Field, California. "Location alone isn't enough, but we know that...        

"Attempt No Voyage Here!" Milky Way Harbors 100 Million Black Holes --'There are Tens of Millions of these Dark Enigmatic Objects Each the Size of 30 Suns' (Today's Most Popular)

"The weirdness of the LIGO discovery" --The detection of gravitational waves created by the merger of two 30-solar-mass black holes (image below) had astronomers asking just how common are black holes of this size, and how often do they merge?...        

Search for Elusive Dark Matter Side of the Universe Dims --"Its Nature Remains Completely Obscure" (VIDEO)

"The results essentially send physicists back to the drawing board in our hunt for dark matter," said Philip Harris, head of Mathematical and Physical Sciences at the University of Sussex. Scientists have disproved the existence of a specific type of...        

"Alien Life Hotspot?" --New Found World is the Closest Warm Planet Orbiting a "Quiet" Red Dwarf Star (VIDEO)

The newfound world is the closest temperate planet known to orbit a “quiet" red dwarf star — one that isn't prone to potentially life-obliterating bursts of radiation. Astronomers using the High Accuracy Radial velocity Planet Searcher (Harps) instrument at the...        

Astronomers Detect New Extreme Species of Ultra-Violent Cosmic Explosion --"In Central, Hidden Region of Galaxies"

The explosion, called PS1-10adi, seems to prefer active galaxies that house supermassive black holes consuming the gas and material around them. Using telescopes on La Palma and Hawaii, astronomers detected an explosion that was so energetic it must have originated...        

Close Encounter of Two Titanic Galaxies from the Big Bang Epoch --"Most-Extreme Violent Star Formation Ever Observed"

"Finding just one hyper-luminous starburst galaxy is remarkable in itself. Finding two of these rare galaxies in such close proximity is truly astounding," said Dominik Riechers, an astronomer at Cornell University and lead author on a paper appearing in the...        

"InfoWars Debunked?" --Scientists Show That Skepticism Towards Conspiracies and the Paranormal Not Just a Matter of Cognitive Ability

In the late 1960s and early 1970s, NASA launched the Apollo missions to the moon that ultimately landed 12 astronauts on the lunar surface in a series of historic missions. Or did they? Yes, the Apollo astronauts did land on...     ...

"Spacetime FM" --Listening for Gravitational Wave Radio Signals Using Pulsars (VIDEO)

"A difference between when the pulsar signals should arrive, and when they do arrive, can signal a gravitational wave," said Chiara Mingarelli, lead study author, who worked on pulsar research as a Marie Curie postdoctoral fellow at Caltech and JPL....        

The Most Amazing Supermassive Spacetime Event in the Cosmos --"Absolutely Dwarfs the Black Hole Mergers Detected by LIGO"

"The gravitational waves from these supermassive black hole binary mergers are the most powerful in the universe," says Chiara Mingarelli, a research fellow at the Center for Computational Astrophysics at the Flatiron Institute in New York City. "They absolutely dwarf...        

Surprising Discovery --"Elements in the Massive Perseus Galaxy Cluster Nearly Identical to the Sun"

"The Perseus cluster is a different environment with a different history from our Sun's. Clusters represent an average chemical distribution from many types of stars in many types of galaxies that formed long before the Sun," said Michael Loewenstein, a...        

"Earth is Our Only Home, There's No Planet B" --World Scientists’ Issue a Second Urgent Warning

Some 15,000 scientists from 184 countries worldwide have signed a letter warning that Earth’s environment is on the road to destruction. The “World Scientists’ Warning to Humanity: Second Notice,” calls for action to avert irreversible damage to the planet. The...        

"Oldest Evidence for Life on Earth" --Life Form from First Two-Billion Years Discovered In the Tasmanian Wilderness World Heritage Area

A team of Tasmanian researchers has uncovered rare, living stromatolites deep within the Tasmanian Wilderness World Heritage Area. Stromatolites are layered mounds, columns, and sheet-like sedimentary rocks. They were originally formed by the growth of layer upon layer of cyanobacteria,...
