A new study simulating stars as they orbit a black hole might provide the best explanation for how our nearest spiral galaxy neighbor grew its lopsided nucleus.
Discovery Channel Telescope's Debut
After seven years of construction, Lowell Observatory's Discovery Channel Telescope is about to come online. The DCT team expects the state-of-the-art 4.3-meter scope to breathe new life into the storied observatory and allow astronomers new views of comets, stars, and deep-space objects.
Ancient Spiral Galaxy Discovered
An ancient spiral galaxy offers another tantalizing clue to how nature might create these grand designs.
Jupiter's Disappearing Act
Skywatchers across the Eastern Hemisphere looked on as the King of Planets briefly ducked behind the Moon on July 15th.
Do-It-Yourself Space Science
A California startup seeks to democratize space research by putting a tiny, custom-built satellite into orbit — and letting the public decide how to use it.
Seeing "Dark" Galaxies
After years of failure, astronomers have finally succeeded in imaging primeval clouds of gas like those that existed before there were stars.
AMA Addresses Light Pollution
The American Medical Association has released a report detailing several possible health concerns related to nighttime light exposure. But some lighting researchers worry the conclusions are more alarmist than is warranted.
July 15th's Occultation of Jupiter
Lucky skywatchers in Europe and northern Asia can watch a waning crescent Moon slide over Jupiter and its Galilean satellites in the hours before and after Sunday morning's dawn.
Auroras Likely July 14-15

Pluto's Moons: Five and Counting
When NASA's New Horizons spacecraft reaches Pluto in three years, it'll have one more object to check out: a tiny fifth moon discovered by the Hubble Space Telescope.
Exoplanet Hunters Dim the Lights
Scientists have devised a new way to dim starlight's blinding glare, a technique that improves on existing technologies to allow astronomers a clearer view of exoplanets orbiting nearby stars.
Sunspot 1520 Rolls Into View
The Sun's spottiness continues with a giant magnetic blotch stretched just below its equator.
