SUNSET: 
Opportunity to Confirm an Asteroid's Moon
On Tuesday morning, August 21, 2007, observers across much of North America should watch for a possible occultation by asteroid 146 Lucina's satellite.
Voyager 2's Lucky Day
Thirty years ago, on August 20, 1977, Voyager 2 left Earth and began its conquest of the outer solar system. Had it not been for the luck of the draw, this historic mission would have turned out very differently.
"Magnificent" Neutron Star Found
Sizzling with X-rays but mum at radio frequencies, a nearby, on-its-own neutron star is causing astronomers to scratch their heads.
The Red Planet We Never Knew
A new DVD entertains with a 50-year-old look at Mars.
Mira's Marvelous Tail
Mira, the closest and brightest of the red long-period variable stars, has thrown off a gassy hood and a comet-like tail so big that if you could see them, they would overflow your telescope's field of view.
One Less "Possibility of Life"?
Just because Saturn's moon Enceladus has active geysers doesn't mean it harbors alien life. That's the take-home message from an upcoming scientific paper.
Bright Galaxies You Can't See
Astronomers have found massive, luminous infrared galaxies 12 billion light-years away. It's not at all clear how they got there.
Uranus and Neptune in 2007
Sky & Telescope diagramThe solar system beyond Saturn has been much in the news in the last year, but just three of its denizens are visible in amateur telescopes. Binoculars readily show Uranus and, with a little more difficulty, Neptune. Pluto normally needs at least an 8-inch telescope and a…
Risky Business
Two American collectors manage — barely — to get in and out of Colombia with fragments from a fresh meteorite fall.
A Great-Grandfather Star
By measuring radioactive decay the same way geologists date rocks on Earth, researchers have pegged the age of a very ancient star in the Milky Way — independently of any other knowledge or assumptions about astronomy.
The Coolest Dwarf
The infrared deep-sky survey now being carried out by the United Kingdom Infrared Telescope is only 5% done, but already astronomers looking at its data have found the coolest solitary brown dwarf ever seen.
New Galaxy Redshift Record
Subtle wisps of galaxies with a redshift around 10 have been detected from the Keck Observatory in Hawaii, claims a group of Caltech astronomers.
"New Star" in Vulpecula
On August 8, 2007, variable-star observer Hiroshi Abe discovered a 9th-magnitude nova in Vulpecula. The AAVSO seeks your observations.
Galaxy Monster Mash
Astronomers using a battery of ground- and space-based telescopes have stumbled upon the most massive galaxy smashup ever seen.
Do Sunspots Forecast the Rain?
A team of researchers claim that sunspot activity might accurately forecast rain in Africa.
Do Sunspots Cycles Forecast the Rain?
A team of researchers claim that sunspot activity might accurately forecast rain in Africa.
Stars that Smoke
Astronomers have resolved carbon soot clouds around one of the sky's best-known R Coronae Borealis–type variable stars.
The Most Puffed-Up Planet
Astronomers have discovered possibly the biggest exoplanet yet. TrES-4 is about 70% wider than Jupiter and has the average density of balsa wood.
