GLASTONBURY, UNITED KINGDOM - SEPTEMBER 28: (EDITORS NOTE: Image has been converted to black and white) The moon is seen prior to the Penumbral Eclipse starting on September 28, 2015 in Somerset, England. Tonight?s supermoon - so called because it is the closest full moon to the Earth this year - is particularly rare as it coincides with a lunar eclipse, a combination that has not happened since 1982 and won?t happen again until 2033.

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.

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.

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.

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.

ISS039-E-013373 (20 April 2014) --- This is one of an extensive series of still photos documenting the arrival and ultimate capture and berthing of the SpaceX Dragon at the International Space Station, as photographed by the Expedition 39 crew members onboard the orbital outpost. The spacecraft was captured by the space station and successfully berthed, following the April 20 arrival.

The SpaceX Dragon arrives at the International Space Station on April 20, 2014. In 2012, the Dragon became the first private spacecraft to dock with the space station. It carries up cargo and brings back trash. SpaceX hopes to take crew members to the space station in the future.

An asteroid is coming! But don't panic. NASA says Asteroid 2012 DA14 will make a record-close pass by Earth on February 15, but it won't hit us. Most asteroids are made of rocks, but some are metal. They orbit mostly between Jupiter and Mars in the main asteroid belt. Scientists estimate there are tens of thousands of asteroids and when they get close to our planet, they are called Near-Earth Objects (NEOs).

Caltech researchers have found evidence of a giant planet tracing a bizarre, highly elongated orbit in the outer solar system. The object, which the researchers have nicknamed Planet Nine, has a mass about 10 times that of Earth and orbits about 20 times farther from the sun on average than does Neptune (which orbits the sun at an average distance of 2.8 billion miles). In fact, it would take this new planet between 10,000 and 20,000 years to make just one full orbit around the sun. - See more at: http://www.caltech.edu/news/caltech-researchers-find-evidence-real-ninth-planet-49523#sthash.JaLsCJd5.dpuf

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.
