August 23, 1966. This photo reveals the first view of Earth from the moon, taken by Lunar Orbiter 1 on August 23, 1966. It’s shot from a distance of about 236,000 miles (380,000 kilometers) and shows half of Earth, from Istanbul to Cape Town and areas east, shrouded in night. NASA restored this photo in 2008, using photographic techniques not available in the 1960s. See the restored photo inside.
The aurora borealis moves slowly above Norway’s Lyngen Alps on a beautiful November night.
Photo above shows Saturday morning’s moon. Will you see the moon Sunday morning? It’ll be tough, but you might. In the meantime, no evening moon means a great time to look toward our Milky Way galaxy’s center.
Astrological signs versus astronomical constellations, how to locate Ophiuchus, some deep-sky treasures it contains, plus charts and more.
Next time you’re brushing you teeth, think on this: Research suggests that the fluorine in your toothpaste was formed billions of years ago in now dead stars.
It’s been a banner year for iceberg sighting in Iceberg Alley, the area off northeastern Newfoundland where the Titanic struck an iceberg and went down in April, 1912.
In 1989, the Voyager 2 spacecraft provided the first close-up view of the planet Neptune and its large moon Triton. This week, NASA scientists released this best-ever global color map of Triton, made with those early Voyager 2 images. The map gives us a glimpse of an otherwise unseen world.
August 22, 1989. When NASA’s Voyager 2 spacecraft skimmed past the planet Neptune on this date, it discovered a faint but continuous ring system encircling the planet. Scientists had suspected there were rings around Neptune some years earlier. After all, Uranus had rings, discovered in 1977. And, watching from Earth in 1984, astronomers were able to see extra blinks before and after Neptune passed in front of a distant star. Still, Voyager 2 made the definitive discovery of Neptune’s rings a few days before it swept closest to the planet.
Think photo opportunity at dawn on August 23, 2014 as the waning crescent moon swings close to the brilliant planets Venus and Jupiter. Darkness will be ebbing to morning twilight. You’ll need an unobstructed eastern horizon, and you’ll want to look low in the sky some 75 to 60 minutes before sunrise. This gorgeous celestial trio – the moon, Jupiter and Venus – is so very bright that some sharp-eyed people might even see the brilliant threesome after sunup.
In a finding that could have implications in the search for life beyond Earth, researchers from an expedition called WISSARD confirmed this week that the waters and sediments of a lake that lies 800 meters (2,600 feet) beneath the surface of the West Antarctic ice sheet support “viable microbial ecosystems.”
