This inner slope of a Martian crater has several of the seasonal dark streaks called "recurrent slope lineae," or RSL, that a November 2017 report interprets as granular flows, rather than darkening due to flowing water. The image is from the HiRISE camera on NASA's Mars Reconnaissance Orbiter.

A photo illustration shows the first interstellar asteroid: `Oumuamua. This unique object was discovered on 19 October 2017 by the Pan-STARRS 1 telescope in Hawai`i. Subsequent observations from ESO's Very Large Telescope in Chile and other observatories around the world show that it was travelling through space for millions of years before its chance encounter with our star system. `Oumuamua seems to be a dark red highly-elongated metallic or rocky object, about 400 metres long, and is unlike anything normally found in the Solar System.

Space & Science

Just 15 minutes after its closest approach to Pluto on July 14, 2015, NASA's New Horizons spacecraft looked back toward the sun and captured this near-sunset view of the rugged, icy mountains and flat ice plains extending to Pluto's horizon. The smooth expanse of the informally named icy plain Sputnik Planum (right) is flanked to the west (left) by rugged mountains up to 11,000 feet (3,500 meters) high, including the informally named Norgay Montes in the foreground and Hillary Montes on the skyline. To the right, east of Sputnik, rougher terrain is cut by apparent glaciers. The backlighting highlights more than a dozen layers of haze in Pluto's tenuous but distended atmosphere. The image was taken from a distance of 11,000 miles (18,000 kilometers) to Pluto; the scene is 780 miles (1,250 kilometers) wide.

This artist's impression shows the temperate planet Ross 128 b, with its red dwarf parent star in the background. This planet, which lies only 11 light-years from Earth, was found by a team using ESO's unique planet-hunting HARPS instrument. The new world is now the second-closest temperate planet to be detected after Proxima b. It is also the closest planet to be discovered orbiting an inactive red dwarf star, which may increase the likelihood that this planet could potentially sustain life. Ross 128 b will be a prime target for ESO's Extremely Large Telescope, which will be able to search for biomarkers in the planet's atmosphere.

A grand grave of a great Viking warrior excavated during the 1880s has been found to be that of a female Viking warrior. She was also buried with a gaming board and pieces, only hierarchically associated with officers to use for battle strategy and tactics.

Illustration of Cassini diving between Saturn and its innermost rings as part of the mission's Grand Finale. The spacecraft will perform a series of 22 daring orbits passing through the yet unexplored region between the planet and its rings and collecting unprecedented data.
Eventually Cassini will plunge and burn up into Saturn's atmosphere on 15 September 2017, satisfying planetary protection requirements to avoid possible contamination of any moons of Saturn that could have conditions suitable for life.

Artist conception of the KELT-9 system. The host star is a hot, rapidly rotating A-type star that is about 2.5 times more massive and almost twice as hot as our sun. The hot star blasts its nearby planet KELT-9b, which transits in front of the star once only 36 hours, with massive amounts of ultraviolet and optical radiation, leading to a dayside temperature of the tidally-locked planet of 7800 degrees Fahrenheit, hotter that most stars and only 2000 degrees cooler than the sun.

http://www.spitzer.caltech.edu/images/1923-ssc2008-10a-A-Roadmap-to-the-Milky-Way

Like early explorers mapping the continents of our globe, astronomers are busy charting the spiral structure of our galaxy, the Milky Way. Using infrared images from NASA's Spitzer Space Telescope, scientists have discovered that the Milky Way's elegant spiral structure is dominated by just two arms wrapping off the ends of a central bar of stars. Previously, our galaxy was thought to possess four major arms.

This artist's concept illustrates the new view of the Milky Way, along with other findings presented at the 212th American Astronomical Society meeting in St. Louis, Mo. The galaxy's two major arms (Scutum-Centaurus and Perseus) can be seen attached to the ends of a thick central bar, while the two now-demoted minor arms (Norma and Sagittarius) are less distinct and located between the major arms. The major arms consist of the highest densities of both young and old stars; the minor arms are primarily filled with gas and pockets of star-forming activity.

The artist's concept also includes a new spiral arm, called the "Far-3 kiloparsec arm," discovered via a radio-telescope survey of gas in the Milky Way. This arm is shorter than the two major arms and lies along the bar of the galaxy.

Our sun lies near a small, partial arm called the Orion Arm, or Orion Spur, located between the Sagittarius and Perseus arms.

Peering through the thick dust clouds of the galactic bulge an international team of astronomers has revealed the unusual mix of stars in the stellar cluster known as Terzan 5.

The exhibition is the first for the fossil outside of Ethiopia and has generated criticism among the museum community and others that believe the fossil is too fragile to be moved from it's home country.

While many other images of the famous Crab Nebula nebula have focused on the filaments in the outer part of the nebula, this image shows the very heart of the Crab Nebula including the central neutron star — it is the rightmost of the two bright stars near the centre of this image. The rapid motion of the material nearest to the central star is revealed by the subtle rainbow of colours in this time-lapse image, the rainbow effect being due to the movement of material over the time between one image and another.

They are the first planets ever discovered around such a tiny and dim star. In this view one of the inner planets is seen in transit across the disc of its tiny and dim parent star.

Just before the 15th anniversary of continuous human presence on the International Space Station on Nov. 2, 2015, U.S. astronaut and commander of the current Expedition 45 crew, Scott Kelly, is breaking spaceflight records. On Friday, Oct. 16, Kelly begins his 383rd day living in space, surpassing U.S. astronaut Mike FinckeÕs record of 382 cumulative days. Kelly will break another record Oct. 29 on his 216th consecutive day in space, when he will surpass astronaut Michael Lopez-AlegriaÕs record for the single-longest spaceflight by an American. Lopez-Alegria spent 215 days in space as commander of the Expedition 14 crew in 2006.

In this July 12 photograph, Kelly is seen inside the Cupola, a special module which provides a 360-degree viewing of the Earth and the space station. On each additional day he spends in orbit as part of his one-year mission, Kelly will add to his record and to our understanding of the effects of long-duration spaceflight.

Kelly is scheduled to return to Earth on March 3, 2016, by which time he will have compiled 522 total days living in space during four missions.

GLASGOW, UNITED KINGDOM - OCTOBER 12: A man suffering from Seasonal Affective Disorder uses a light box in his office to combat the illness on October 12 2005 in Glasgow, Scotland. Seasonal affective disorder (SAD), or winter depression, is a mood disorder related to the change in the seasons and the resulting reduction of exposure to daylight. The end of British Summer time, when clocks go back one hour at the end of October, will see most people making their daily commute in darkness both ways. With winter nights stretching to 19 hours in the UK, and Scotland's often inclement weather, it is estimated that the 'Winter Blues' can affect up to 20% of the population.

I wanted to share our story because there is one thing that was missing throughout our whole journey. That was the lack of friends or people that we going through it as well.
