New NASA Images: The Geysers of Saturn's Enceladus

 

 

N00250071

 

NASA's Cassini spacecraft has begun transmitting its latest images of Saturn's icy, geologically active moon Enceladus, acquired during the dramatic Oct. 28 flyby in which the probe passed about 30 miles (49 kilometers) above the moon's south polar region. The spacecraft will continue transmitting its data from the encounter for the next several days.

Image of the Day: Ancient Mystery Earthworks So Massive NASA is Imaging Them From Space

During the past few years, archaeologists have revealed more than 200 massive Turgai, Kazakhstan earthworks, called Steppe Geoglyphs, or the Turgai Geoglyphs, so large they are not obvious from Earth. They were discovered by a Kazakh archaeologist browsing Google Earth in 2007. While clicking over the seemingly empty landscape, he saw remarkable patterns in the soil: crosses, boxes, swastikas, circles, and more, created from mounts of dirt only three feet high and roughly 30 feet wide. All in all, there are now 260 known geoglyphs that NASA has been imaging NASA since 2012.

China Building World's Most Massive Particle Accelerator --"Capable of Producing Millions of Higgs Bosons"

China is planning to build an enormous particle accelerator twice the size and seven times as powerful as CERN’s Large Hadron Collider, according to state media reports. According to China Daily, the new facility will be capable of producing millions of Higgs boson particles - a great deal more than the Large Hadron Collider which originally discovered the ‘God particle’ back in 2012. The first phase of the project's construction is scheduled to begin between 2020 and 2025

NASA Kepler Mission: "Finding Alien Worlds with a Play of Light and Shadow"

Astronomers have used many different methods to discover planets beyond the solar system, but the most successful by far is transit photometry, which measures changes in a star's brightness caused by a mini-eclipse. When a planet crosses in front of its star along our line of sight, it blocks some of the star's light. If the dimming lasts for a set amount of time and occurs at regular intervals, it likely means an exoplanet is passing in front of, or transiting, the star once every orbital period.

Astrophysicists May Soon Announce Earth's Twin Around a Distant Star --"Exotic Clouds or Haze a Key"

Scientists have cataloged nearly 2,000 exoplanets around stars near and far. While most of these are giant and inhospitable, improved techniques and spacecraft have uncovered increasingly smaller worlds. The day may soon come when astrophysicists announce our planet's twin around a distant star.

NASA: "Spiral Stars Signal the Presence of Giant Planets"

A team of astronomers is proposing that huge spiral patterns seen around some newborn stars, merely a few million years old (about one percent our sun's age), may be evidence for the presence of giant unseen planets. This idea not only opens the door to a new method of planet detection, but also could offer a look into the early formative years of planet birth.

NASA's Voyager 1 --"Poised to Probe Many Longstanding Mysteries"

"There are still naysayers out there regarding Voyager 1 crossing through the heliopause--the edge of the heliosphere," says astrophysicist Nathan Schwadron of the UNH Institute for the Study of Earth, Oceans, and Space and department of physics and lead author of the paper. "And the reason for this doubt is that when the spacecraft supposedly broke through the heliopause we should have seen some sort of distinctive shift in the magnetic field from one medium to the other."

Q Continuum Project: Reveals "How Gravity Acts on Dark Matter of the Universe"

Researchers are sifting through an avalanche of data produced by one of the largest cosmological simulations ever performed, run on the Titan supercomputer at DOE's Oak Ridge National Laboratory. The project modeled the evolution of the universe from just 50 million years just 50 million years after the Big Bang to the present day -- from its earliest infancy to its current adulthood. Over the course of 13.8 billion years, the matter in the universe clumped together to form galaxies, stars and planets; but we're not sure precisely how.

Jupiter's 4-Billion-Year-Old Close Encounter --"Ejected a 5th Gas-Giant Planet from Solar System'

The existence of a fifth giant gas planet at the time of the Solar System's formation - in addition to Jupiter, Saturn, Uranus and Neptune that we know of today - was first proposed in 2011. But if it did exist, how did it get pushed out? For years, scientists have suspected the ouster was either Saturn or Jupiter.

NASA's Apollo Mystery Solved: Organic Matter Found in Mission Lunar Samples

A team of NASA-funded scientists has solved an enduring mystery from the Apollo missions to the moon - the origin of organic matter found in lunar samples returned to Earth. Samples of the lunar soil brought back by the Apollo astronauts contain low levels of organic matter in the form of amino acids. Certain amino acids are the building blocks of proteins, essential molecules used by life to build structures like hair and skin and to regulate chemical reactions.
