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.

“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.

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.

The lift off of the SpaceX rocket marked the first flight from the Apollo-era launch pad since the retirement of the space shuttle six years ago. SpaceX upgraded the pad, replacing its ground systems and adding an new transporter erector launcher.

Hubble Spotlights a Celestial Sidekick

This image was captured by the NASA/ESA Hubble Space Telescope’s Advanced Camera for Surveys (ACS), a highly efficient wide-field camera covering the optical and near-infrared parts of the spectrum. While this lovely image contains hundreds of distant stars and galaxies, one vital thing is missing — the object Hubble was actually studying at the time!

This is not because the target has disappeared. The ACS actually uses two detectors: the first captures the object being studied — in this case an open star cluster known as NGC 299 — while the other detector images the patch of space just ‘beneath’ it. This is what can be seen here.

Technically, this picture is merely a sidekick of the actual object of interest — but space is bursting with activity, and this field of bright celestial bodies offers plenty of interest on itsown. It may i... more »

Technically, this picture is merely a sidekick of the actual object of interest — but space is bursting with activity, and this field of bright celestial bodies offers plenty of interest on its own. It may initially seem to show just stars, but a closer look reveals many of these tiny objects to be galaxies. The spiral galaxies have arms curving out from a bright center. The fuzzier, less clearly shaped galaxies might be ellipticals. Some of these galaxies contain millions or even billions of stars, but are so distant that all of their starry residents are contained within just a small pinprick of light that appears to be the same size as a single star!

The bright blue dots are very hot stars, sometimes distorted into crosses by the struts supporting Hubble’s secondary mirror. The redder dots are cooler stars, possibly in the red giant phase when a dying star cools and expands.

Single-event upset

"You may not realize it but alien subatomic particles raining down from outer space are wreaking low-grade havoc on your smartphones, computers and other personal electronic devices.

When your computer crashes and you get the dreaded blue screen or your smartphone freezes and you have to go through the time-consuming process of a reset, most likely you blame the manufacturer: Microsoft or Apple or Samsung. In many instances, however, these operational failures may be caused by the impact of electrically charged particles generated by cosmic rays that originate outside the solar system.

"The distribution of normal matter precisely determines gravitational acceleration in all common types of galaxies, a team led by Case Western Reserve University researchers reports.

The team has shown this radial acceleration relation exists in nearby high-mass elliptical and low-mass spheroidal galaxies, building on last year's discovery of this relation in spiral and irregular galaxies. This provides further support that the relation is tantamount to a new natural law, the researchers say.

"This demonstrates that we truly have a universal law for galactic systems," said Federico Lelli, formerly an astronomy postdoctoral fellow at Case Western Reserve University and currently a fellow at the European Southern Observatory.

"The distribution of normal matter precisely determines gravitational acceleration in all common types of galaxies, a team led by Case Western Reserve University researchers reports.

The team has shown this radial acceleration relation exists in nearby high-mass elliptical and low-mass spheroidal galaxies, building on last year's discovery of this relation in spiral and irregular galaxies. This provides further support that the relation is tantamount to a new natural law, the researchers say.

"This demonstrates that we truly have a universal law for galactic systems," said Federico Lelli, formerly an astronomy postdoctoral fellow at Case Western Reserve University and currently a fellow at the European Southern Observatory.

"This is similar to the Kepler law for planetary systems, which does not care about the specific properties of the planet. Whether the planet is rocky like Earth or gaseous like Jupiter, the law applies," said Lelli, who led this investigation.

In this case, the observed acceleration tightly correlates with the gravitational acceleration from the visible mass, no matter the type of galaxy. In other words, if astronomers measure the distribution of normal matter, they know the rotation curve, and vice versa.

"But it is still unclear what this relation means and what is its fundamental origin," Lelli said.

The study is published online in Astrophysical Journal today. Co-authors are Stacy McGaugh, chair of the Department of Astronomy at Case Western Reserve, James Schombert, astronomy professor at the University of Oregon, and Marcel Pawlowski, former astronomy postdoctoral researcher at Case Western Reserve and current Hubble fellow at the University of California, Irvine."

Wow. Key ingredients of Life possibly found on Ceres!

"NASA's Dawn spacecraft recently detected organic-rich areas on Ceres. Scientists evaluated the geology of the regions to conclude that the organics are most likely native to the dwarf planet. Data from the spacecraft suggest that the interior of Ceres is the source of these organic materials, as opposed to arriving via impacting asteroids or comets, according to a paper published in the Feb. 17, 2017, issue of Science.

"This discovery of a locally high concentration of organics is intriguing, with broad implications for the astrobiology community," said Dr. Simone Marchi, a senior research scientist at Southwest Research Institute and one of the authors of the paper. "Ceres has evidence of ammonia-bearing hydrated minerals, water ice, carbonates, salts, and now organic materials. With this new... more »

Venus brightest this week: http://bit.ly/2lVIDj4

Look west after sunset!

Greatest brilliancy for Venus happens near the time the planet goes between us and the sun ... so if you saw Venus through a telescope now, it'd appear in a crescent phase.

Big improvements to brain-computer interface - When people suffer spinal cord injuries and lose mobility in their limbs, it's a neural signal processing problem. The brain can still send clear electrical impulses and the limbs can still receive them, but the signal gets lost in the damaged spinal cord.

“ What they find is that the transition from “rocky” world to “gaseous” world occurs at just twice the Earth’s mass. If you’re more that twice the mass of Earth and you receive the same amount of energy from your star, you’ll be able to hold onto a substantial hydrogen-and-helium envelope of gas, creating an atmospheric pressure that’s hundreds or even thousands of times as great as what we have on Earth’s surface.

It was quite a surprise when we started discovering all the exoplanets that were out there. While there’s a big gap between a world like Earth and a world like Uranus or Neptune in our Solar System – 17 times the mass and 4 times the radius – most of the worlds out there fall in between these two types. Super-Earths and Mini-Neptunes are the most common. But it turns out that what we’re calling a “Super-Earth” is a total misnomer! These worlds may be larger than Earth, but they’re much more like Uranus or Neptune than they are like our own. They have big gas envelopes surrounding them, and can even hold on to their young hydrogen and helium. The only way out is to boil the atmosphere away, and if you do, you’ve got a rocky core that’s close enough to its star to be roasted.

Come find out the full story behind why there’s no such thing as a habitable Super-Earth!___
