"Comets travel much faster than asteroids, and some of them are very big," said Amy Mainzer, co-author based at NASA's Jet Propulsion Laboratory, Pasadena, California, and principal investigator of the NEOWISE mission. "Studies like this will help us define what... Continue reading

“Our team predicted exactly where to find the Majorana fermion and what to look for as its ‘smoking gun’ experimental signature,” said Zhang, a theoretical physicist and one of the senior authors of the research paper. “This discovery concludes one... Continue reading

Campi Flegrei, "burning fields", is a supervolcano that consists of a vast and complex network of underground chambers that formed hundreds of thousands of years ago, stretching from the outskirts of Naples to underneath the Mediterranean Sea and last erupted... Continue reading

"The growing evidence for water inside the Moon suggest that water did somehow survive, or that it was brought in shortly after the impact by asteroids or comets before the Moon had completely solidified," said Shau Li at Brown University.... Continue reading

Gravitational lenses are at the forefront of current research in cosmology and astrophysics. In astrophysics, they have been used to uncover the structure of massive galaxies, to study how supermassive black holes relate to their host galaxies, and to gain... Continue reading

As NASA's Cassini spacecraft makes its unprecedented series of weekly dives between Saturn and its rings, scientists are finding—so far—that the planet's magnetic field has no discernable tilt. This surprising observation, which means the true length of Saturn's day is... Continue reading

Dark matter is the aptly named unseen material that makes up the bulk of matter in our universe. But what dark matter is made of is a matter of debate. Scientists have never directly detected dark matter. But over decades,... Continue reading

The death of a massive star in a distant galaxy 10 billion years ago created a rare superluminous supernova that astronomers say is one of the most distant ever discovered. The brilliant explosion, more than three times as bright as... Continue reading

"This is an incredibly exciting discovery. We can clearly conclude that the same breaking of symmetry can be observed in any physical system, whether it occurred at the beginning of the universe or is happening today, right here on Earth,"... Continue reading

Correlated noise in the two LIGO gravitational-wave detectors may provide evidence that the universe is governed by conformal cyclic cosmology (CCC) which assumes that the universe consists of a succession of aeons, says Roger Penrose of the University of Oxford.... Continue reading

Across the world, sharks congregate around volcanoes and volcanic islands. From active, dormant to extinct, volcanoes hold a strong attraction for sharks of all kinds, but little is known about this phenomenon. A team from Florida International University went in... Continue reading

A new documentary came out on Netflix last week. It’s called "Chasing Coral," and it looks at the impact of coral bleaching on reefs unless CO2 emissions are reduced. At World Heritage-listed reefs, including Australia’s Great Barrier Reef or Phoenix... Continue reading

Every moment of your waking life and whenever you dream, you have the distinct inner feeling of being “you.” When you see the warm hues of a sunrise, smell the aroma of morning coffee or mull over a new idea,... Continue reading

In saliva, scientists have found hints that a "ghost" species of archaic humans may have contributed genetic material to ancestors of people living in Sub-Saharan Africa today. The research adds to a growing body of evidence suggesting that sexual rendezvous... Continue reading

"It's harder to distinguish between a microbe and a speck of dust than you'd think," says Nadeau, research professor at Caltech of medical engineering and aerospace. "You have to differentiate between Brownian motion, which is the random motion of matter,... Continue reading

One of the primary open questions of astrobiology is whether there is extant or extinct life elsewhere the Solar System. Some scientists such as Penn State astrophysicist Jason Wright, a member of the Center for Exoplanets and Habitable Worlds, have... Continue reading

Star Trek's" mission to explore strange new worlds, to seek out new life and new civilizations, to boldly go where no one has gone before is symbolized by captain William Shatner who narrates a new 45-minute documentary about NASA's Langley... Continue reading

As the "Land Down Under," Australia is an island continent, so ancient visitors would have to arrived by sea, a long way from where humans first evolved in Africa. Migration to Australia would have required some remarkable ingenuity. Archaeologists have... Continue reading

"We are going to be the generation that is remembered for finding exoplanets. That's a fact," said Mercedes López-Morales from the Harvard Center for Astrophysics. "Are we going to be also the generation that will be remembered as the first... Continue reading

Physicists are capitalizing on a direct connection between the largest cosmic structures and the smallest known objects to use the universe as a "cosmological collider" and investigate new physics. The cosmos' tiniest particles and the distribution of matter across the... Continue reading

Einstein's theory of gravity may have to be rewritten, after researchers at the University of St Andrews found a gigantic ring of galaxies darting away from us much faster than predicted. This 10 million light year-wide ring made up of... Continue reading

We recently reported on an enormous galaxy that at its core contains an equivalent to 140 trillion times all the water in the world's ocean, surrounding a huge, feeding black hole, called a quasar, more than 12 billion light-years away.... Continue reading

Today's Galaxy Steam features two videos. The first from Isaac Arthur on the possibilities of first contact with an advanced civilization and the second featuring astronomers Martin Rees (see interview below) and Seth Shostak on the search for intelligent life.... Continue reading
