Exactly two years from today, on Aug. 21, 2017, a rare total solar eclipse will be seen again in the skies of the United States, racing east from Oregon to South Carolina. For a brief couple of minutes, the skies will darken as the Moon passes in front of the Sun, revealing the Sun’s corona, which is not normally visible in daylight, to millions of people as it crosses coast to coast for the first time in nearly a century. A total solar eclipse is one of the greatest sights in nature, not to be missed, and many are already making plans to witness the event.

The existence of neon gas in our Moon’s ultra-thin atmosphere has been confirmed for the first time, by NASA’s Lunar Atmosphere and Dust Environment Explorer (LADEE) spacecraft. Its presence had been theorized for decades, but has now finally been confirmed and found to be relatively abundant, even though it’s not nearly enough for the Moon to actually glow like a neon sign.
A beautiful and unique view of the Moon passing in front of the Earth as seen from the Deep Space Climate Observatory (DSCOVR) satellite. The far side of the Moon, never seen from Earth, is visible here as the Moon passes between the satellite and Earth. The video animation is here. The images were taken between 3:50 p.m. and 8:45 p.m. EDT on July 16, 2015 from 1,609,000 kilometres (1,000,000 miles) away.
Here are a couple of new images taken by the Chinese Chang’e 3 lander and Yutu rover on the Moon. Much better resolution than the first earlier images and nice to finally have some new views from the lunar surface after all these decades! An interesting change from the Mars rovers, which look at a bright, dusty Martian sky, while here there is virtually no atmosphere and perpetual blackness overhead…
After a very successful landing by the Chang’e 3 spacecraft on Saturday, the attached rover, called Yutu or “Jade Rabbit,” detached itself from the lander yesterday, rolling off a ramp and onto the lunar surface at 4:30 am Beijing time.
The landing by a Chinese spacecraft is the first soft landing on the Moon since the manned Apollo missions ended in the 1970s and the Soviet Union’s Luna 24 lander in 1976. Like the launch and landing, the release of the rover was virtually flawless, allowing China to celebrate its continued space exploration achievements in recent years.
Yutu is a six-wheeled, 140 kg (308 pound) solar-powered rover which will explore the landing area of Sinus Iridum or “Bay of Rainbows.” Compared to the Mars rovers, Yutu is rather small, measuring only about 1.5 metres long (with its solar panels folded) but will be capable of conducting detailed analysis of rocks and soil during its nominal 3-month mission. It even has ground-penetrating radar under its belly which can reach below the surface to a depth of about 30-100 metres (100-330 feet).
The full landing sequence video of Chang’e 3 can be watched here.
China is now only the third country to have landed on the Moon, after the United States and the former Soviet Union.

Using lasers to communicate at planetary distances is something that may sound like sci-fi, but it is a real technology being developed by NASA as a means of communicating with spacecraft faster and more efficiently than can be done now.
The prospect of when, or even if, NASA astronauts will return to the Moon has been a subject of much debate in recent years. Some experts see it as a necessary stepping stone before future Mars missions. Others see it as a case of “been there, done that.”
Images taken by the Lunar Reconnaissance Orbiter have helped to answer a long-standing question about the old Apollo landing sites on the Moon – are any of the flags planted there by the astronauts still standing today? It turns out that yes, almost all of them are.

For hundreds of years, people have seen tiny flashes of light on the surface of the Moon. Very brief, but bright enough to be seen from Earth, these odd flashes still hadn’t been adequately explained up until now. Also known as Transient Lunar Phenomena (TLPs), they’ve been observed on many occasions, but rarely photographed. On Earth, meteorites burning up in the atmosphere can produce similar flashes, but the Moon has no atmosphere for anything to burn up in, so what could be causing them? As it turns out, according to a new study, the answer is still meteorites, but for a slightly different reason…

Two researchers at Arizona State University (ASU) have made a rather controversial proposal: have the public and other researchers study the high-resolution photographs of the Moon already being taken by the Lunar Reconnaissance Orbiter (LRO), to look foranomalies that may possibly be evidence of artifacts leftover from previous alien visitation. The theory is that if our solar system had been visited in the past, the Moon would have made an ideal base from which to study the Earth. The paper has just been recently published in the journal Acta Astronautica…
