Explanation: It's raining stars. What appears to be a giant cosmic umbrella is now known to be a tidal stream of stars stripped from a small satellite galaxy. The main galaxy, spiral galaxy NGC 4651, is about the size of our Milky Way, while its stellar parasol appears to extend some 100 thousand light-years above this galaxy's bright disk. A small galaxy was likely torn apart by repeated encounters as it swept back and forth on eccentric orbits through NGC 4651. The remaining stars will surely fall back and become part of a combined larger galaxy over the next few...

Explanation: Are these trees growing on Mars? No. Groups of dark brown streaks have been photographed by the Mars Reconnaissance Orbiter on melting pinkish sand dunes covered with light frost. The featured image was taken in 2008 April near the North Pole of Mars. At that time, dark sand on the interior of Martian sand dunes became more and more visible as the spring Sun melted the lighter carbon dioxide ice. When occurring near the top of a dune, dark sand may cascade down the dune leaving dark surface streaks -- streaks that might appear at first to be trees...

Explanation: Tidally locked in synchronous rotation, the Moon always presents its familiar nearside to denizens of planet Earth. From lunar orbit, the Moon's farside can become familiar, though. In fact this sharp picture, a mosaic from the Lunar Reconnaissance Orbiter's wide angle camera, is centered on the lunar farside. Part of a global mosaic of over 15,000 images acquired between November 2009 and February 2011, the highest resolution version shows features at a scale of 100 meters per pixel. Surprisingly, the rough and battered surface of the farside looks very different from the nearside covered with smooth dark lunar maria....

The Kansas City Star reports that Peruvian authorities made a stunning new discovery at the site of Era de Pando in the Supe Valley. The region was home to the Caral culture, which is often considered the oldest city-building civilization in the Americas. Previous excavations at Era de Pando have unearthed four large and four small pyramid complexes, and at least 40 other buildings, including houses and temples, that date back at least 4,000 years. While working near one of the largest pyramids, archaeologists recently uncovered the ruins of a structure known as a "fire altar." The circular feature, which...

A bison was gruesomely boiled to death in a Yellowstone National Park hot spring last week — as tourists watched in horror. The buffalo met its ghastly end when it apparently stumbled into the scalding water at Midway Geyser Basin near Old Faithful, according to the park service. “There were two bison [standing] there,” said Louise Howard, who witnessed the bison’s death during her first-ever visit to Yellowstone, to CBS News. “I thought it was a great photo opportunity.” But the shutter-worthy sight quickly turned tragic when one of the bison stepped into a small part of the basin, then...

Anadolu Agency reports that excavations at the site of Olympos in the current-day region of Antalya revealed new evidence that attests to the site's early Christian history. Inside a building known as Church No. 1, the team uncovered mosaic floors featuring geometric patterns, floral motifs, and Greek inscriptions, some of which bear the names of individuals who are believed to be among the church's early benefactors. "These finds confirm Olympos as one of the richest ancient cities in the Lycia region in terms of mosaic flooring," said excavation director Gökçen Kurtuluş Öztaşkın. Another inscription near the structure's entrance reads, "Only...

Credit: DavidMPyle / CC BY-SA 4.0 =================================================================== A steady underground pulse has been discovered beneath East Africa, where researchers believe a new ocean is gradually forming. The rhythmic movement was detected in the Afar region of Ethiopia, a geological hotspot where three giant sections of the Earth’s crust—the Arabian, Nubian, and Somalian plates—are slowly pulling apart. The site, known as the Afar Triple Junction, is one of few places on Earth where the process of continental breakup can be observed on land. As the plates drift in different directions, the ground...

Explanation: Big beautiful barred spiral galaxy Messier 109 is the 109th entry in Charles Messier's famous catalog of bright Nebulae and Star Clusters. You can find it just below the Big Dipper's bowl in the northern constellation Ursa Major. In fact, bright dipper star Phecda, Gamma Ursa Majoris, produces the glare at the upper right corner of this telescopic frame. M109's prominent central bar gives the galaxy the appearance of the Greek letter "theta", θ, a common mathematical symbol representing an angle. M109 spans a very small angle in planet Earth's sky though, about 7 arcminutes or 0.12 degrees. But...

When archaeologists were called to investigate a sinkhole that opened up in the city of York, they were surprised to find traces of a medieval hospital, according to a report by The Independent. The team encountered walls hidden just beneath the city streets that they believe once belonged to the twelfth- or thirteenth-century St. Leonard's Hospital. The institution was built just after the Norman conquest and replaced the earlier St. Peter's Hospital, which was founded by the Anglo-Saxon King Aethelstan. Stretching from what is now York's Museum Gardens to the Theatre Royal, St. Leonard's was one of the largest hospitals...
