"The Earth's core consists mostly of a huge ball of liquid metal lying at 3000 km beneath its surface, surrounded by a mantle of hot rock. Notably, at such great depths, both the core and mantle are subject to extremely high pressures and temperatures. Furthermore, research indicates that the slow creeping flow of hot buoyant rocks—moving several centimeters per year—carries heat away from the core to the surface, resulting in a very gradual cooling of the core over geological time. However, the degree to which the Earth's core has cooled since its formation is an area of intense debate amongst Earth scientists."

Not just special, but unique, at least among the planets we’ve found so far. But there are other planetary systems out there with Earth-like worlds. Similar to Earth in mass, size, temperature and many other conditions, these might represent planets where life similar to what we find here arose. For the first time, we’ve found a planetary system with not just one Earth-like, potentially habitable world, but three!

Mars Life Could Lurk Within These Salty Streaks

Life as we know it requires liquid water. So you can imagine the excitement when, in 2015, hydrated minerals — or compounds that form in the presence of water — were seen on the same Martian slopes as mysterious features known as "recurring slope lineae" or, simply, RSL.

First imaged in high resolution by NASA's Mars Reconnaissance Orbiter (MRO) in 2006, these features tend to appear and disappear over several months, appearing at times when the sun shines most strongly upon those slopes. Now, the theory is that these RSL could be seasonal flows of water flowing down the slopes. On Earth, where there's water, there's life — could this hold true for the Red Planet?

The challenge for life on Mars is that this water is extremely salty, with a far higher salt concentration than the limit known for Earth microbes. But they are still regions of interest for possible life, and a potential source of water for future Mars exploration.

A new paper published in the journal Astrobiology argues that we should make studying these features a priority.

A Piece of Mars: Who wins in the fight of wind vs. ice? | Lori Fenton's Blog

This is the crest of one of the largest dunes on Mars (0.5×0.5 km or 0.31×0.31 mi). The wind mostly blows from the right, slowly pushing sand up the windward slope. But frost accumulates on (and probably in) the sand during winter, and sometimes it gets too heavy and slides down the steepest slope (toward the left), carving out big gullies in the sand. And then the wind blows some more, trying to erase the gullies by 1) making ripples, 2) burying the gullies (the featureless blue patches are grainfall, which is a fancy term for sand that fell as airfall), and 3) forming dust devils that leave faint but wide tracks. Who wins this fight, wind or ice? Neither: gravity wins (it usually does).

" On Wednesday, Dragon encountered a fault within a filter in its GPS System, in charge of processing the Relative GPS data collected by the spacecraft itself and transmitted by ISS through the UHF communications link. SpaceX engineers in Hawthorne, California immediately started the process of diagnosing the issue with the initial suspicion that Dragon’s computers were provided an incorrect ISS state vector that did not converge with the GPS data Dragon received.

Europa Mission Heralds Sea Change in the Search for Alien Life

After decades of wandering in Martian deserts, NASA’s astrobiologists are at last preparing to rekindle a direct search for a “second genesis” of life in our solar system—but not where one might think. This time, they will look well beyond Mars, the most Earthlike of our planetary neighbors, to the dark reaches of the outer solar system, where probes and space telescopes have revealed ever-more tantalizing signs of oceans hidden inside icy moons and dwarf planets. Warmed by tidal forces rather than sunlight, those environments could harbor life, scientists say. “These oceans may be close to the surface, or may be deeper, with thicker ice crusts, but there must be water in liquid or slush form there—even all the way out to Pluto,” says James Green, director of NASA’s Planetary Science Division and an architect of theagency’s embryo... more »

Europa Mission Heralds Sea Change in the Search for Alien Life

The program’s central focus is Europa, a moon of Jupiter that despite being slightly smaller than Earth’s lunar companion is thought to contain an ocean twice as voluminous as all our planet’s seas combined. Data from previous spacecraft flybys hint Europa’s ocean is billions of years old and in direct contact with the moon’s hot, rocky core, offering life sufficient time and energy to get started somewhere within. Locked below a crust with an average thickness of at least dozens of kilometers, any Europan biosphere might have remained forever out of reach. Occasionally seawater wells up through fissures in the crust to freeze at or near the surface, however, and recent observations by the Hubble Space Telescope suggest the ocean may even be venting vast amounts of water vapor into space through geyserlike plumes erupting from beneath the surface. If astronomers could collect the frozen material or the vapor they might learn what, if anything, lurks within Europa.

"NASA's Fermi Gamma-ray Space Telescope has found a signal at the center of the neighboring Andromeda galaxy that could indicate the presence of the mysterious stuff known as dark matter. The gamma-ray signal is similar to one seen by Fermi at the center of our own Milky Way galaxy.

Gamma rays are the highest-energy form of light, produced by the universe's most energetic phenomena. They're common in galaxies like the Milky Way because cosmic rays, particles moving near the speed of light, produce gamma rays when they interact with interstellar gas clouds and starlight.

Gamma rays are the highest-energy form of light, produced by the universe's most energetic phenomena. They're common in galaxies like the Milky Way because cosmic rays, particles moving near the speed of light, produce gamma rays when they interact with interstellar gas clouds and starlight.

Surprisingly, the latest Fermi data shows the gamma rays in Andromeda—also known as M31—are confined to the galaxy's center instead of spread throughout. To explain this unusual distribution, scientists are proposing that the emission may come from several undetermined sources. One of them could be dark matter, an unknown substance that makes up most of the universe.

"We expect dark matter to accumulate in the innermost regions of the Milky Way and other galaxies, which is why finding such a compact signal is very exciting," said lead scientist Pierrick Martin, an astrophysicist at the National Center for Scientific Research and the Research Institute in Astrophysics and Planetology in Toulouse, France. "M31 will be a key to understanding what this means for both Andromeda and the Milky Way."

A paper describing the results will appear in an upcoming issue of The Astrophysical Journal."

Galactic star formation rates measured to the highest precision yet

"A team led from the Instituto de Astrofísica de Canarias (IAC) has found the most precise way ever to measure the rate at which stars form in galaxies using their radio emission at 1-10 Gigahertz frequency range.

Almost all the light we see in the universe comes from stars which form inside dense clouds of gas in the interstellar medium. The rate at which they form (referred to as the star formation rate, or SFR) depends on the reserves of gas in the galaxies and the physical conditions in the interstellar medium, which vary as the stars themselves evolve. Measuring the star formation rate is hence key to understand the formation and evolution of galaxies."

Featured Image: Structures in the Interstellar Medium

This beautiful false-color image (which covers ~57 degrees2) reveals structures in the hydrogen gas that makes up the diffuse atomic interstellar medium at intermediate latitudes in our galaxy. The image was created by representing three velocity channels with colors — red for gas moving at 7.59 km/s, green for 5.12 km/s, and blue for 2.64 km/s — and it shows the dramatically turbulent and filamentary structure of this gas. This image is one of many stunning, high-resolution observations that came out of the DRAO HI Intermediate Galactic Latitude Survey, a program that used the Synthesis Telescope at the Dominion Radio Astrophysical Observatory in British Columbia to map faint hydrogen emission at intermediate latitudes in the Milky Way. The findings from the program were recently published in a study led by Kevin Blagrave (CanadianIns... more »

“While the large Moon will be destined to be tidally destroyed and drawn to the surface through friction with Mars’ atmosphere, the other two moons could remain. Phobos and Deimos had a much larger sibling at some point in the past, but it may have lasted only for a few million years. After billions of years more, these two small moons remain. Perhaps in a few billion more, Phobos may be destroyed as well. If the new theory is right, a future scientist will only have Deimos and the basins on Mars to piece together this story from.

It’s a stark reminder that in the Solar System and the Universe in general, the past is gone. All we have left to base its history on are the survivors.”

Compared to the other moons we know of in the Solar System, Mars’s two, Phobos and Deimos, are incredibly difficult to explain. They look like captured asteroids, being small, irregular, and exhibiting the right surface features. But captured asteroids form inclined or even retrograde orbits quite distant from their planet, while Phobos and Deimos live in circular, equatorial, close-in orbits to Mars. An alternative theory to the captured asteroid scenario is that the moons of Mars formed from a giant impact that kicked up a circumplanetary debris disk, similar to how Earth’s moon formed. But those scenarios never lead to merely two small moons; there’s always at least one large one. Thanks to a new simulation, all the pieces might finally be coming together.

Could Mars have had an inner, larger moon in the past that’s now decayed and collided back with the red planet? Get the story today!___

Kepler's 'second life' – DLR researchers find six planets

In 2009, +NASA's #Kepler space probe was launched, embarking on a mission to hunt for #exoplanets. In 2013, due to the failure of two of its reaction wheels, the mission had to be modified.This 'second life' was dubbed #K2. Researchers from #DLR, together with colleagues from other institutions, have now analysed the K2 data and discovered six new planets around other stars, including two extraordinary companions to a star one and a half times the mass of the Sun.

Persistently Active Neurons Vital To Short Term Memory Support

Researchers found persistently active neurons in the medial frontal lobe as well as the medial temporal lobe. The neurons remained active even after the patient stopped looking at an image or object.

Until now, the medial temporal lobe was thought to be involved only in the formation of new long-term memories. Now, however, the new findings show that both areas of the brain are critical for maintaining short-term memory and rely upon the ongoing activity of the neurons for memorization.

ESA’s #XMMNewton has found a #pulsar – the spinning remains of a once-massive star – that is a thousand times brighter than previously thought possible. The pulsar is also the most distant of its kind ever detected, with its light travelling 50 million light-years before being detected by XMM-Newton.

A Clear and Distant Past

Over the weekend I was with some friends atop Mason Hill in Driftwood, Pennsylvania. That's not terribly far from Cherry Springs Dark Sky Park, which boasts one of the darker skies of our region. The bright center of the Milky Way isn't out this time of year around here, but the stars were still beautiful and worth appreciating.

This was one 30-second exposure with the Sony Vario-Tessar T* FE 16-35mm f/4 ZA OSS Lens. The color on the horizon is from some semi-nearby city/town.

East of the Mississippi in the United States, they barely exist at all. From many urban locations, even bright, easily recognizable sights like the North Star or the Big Dipper are no longer visible.

Come see what light pollution costs us every night, and learn why, if we don’t do something, the only place to get dark skies will be in space.___

APOD: 2017 February 20 - Almost Three Tails for Comet Encke

Image Credit & Copyright: Fritz Helmut Hemmerich

How can a comet have three tails? Normally, a comet has two tails: an ion tail of charged particles emitted by the comet and pushed out by the wind from the Sun, and a dust tail of small debris that orbits behind the comet but is also pushed out, to some degree, by the solar wind. Frequently a comet will appear to have only one tail because the other tail is not easily visible from the Earth. In the featured unusual image, Comet 2P/Encke appears to have three tails because the ion tail split just near to the time when the image was taken. The complex solar wind is occasionally turbulent and sometimes creates unusual structure in an ion tail. On rare occasions even ion-tail disconnection events have been recorded.
