With a small telescope and our sky charts, you can watch a very sizable near-Earth asteroid race across winter’s constellations on the night of January 26-27.
The best place to look for nearby Earth-size planets are around the smallest, coolest stars. New research shows that any exoplanets tightly circling their stars might have a better chance of being habitable than previously thought.
As the Kepler mission shifts into its new mode of operations, multiple new searches for exoplanets are in the works.
Hubble Space Telescope observations are adding a third dimension to previously 2D images – and enlightening astronomers about the evolution of galaxies in the distant universe.
On December 25, 2003, a British-built lander dropped to the Martian surface and disappeared without a trace. Now we know what happened to it.
A waxing crescent Moon, dim Mars, and bright Venus show in the evening skies this weekend. Despite the growing Moon, fading Comet Lovejoy remains a lovely sight. Plus, don’t miss tonight’s rare triple shadow transit on Jupiter.
Comet Lovejoy is about magnitude 4.2, high in the evening sky for your binoculars or low-power, wide-field telescope. Catch these last best nights — the Moon starts to brighten the sky in just a few days!
For the second time in as many months, the periodic comet 15P/Finlay has surged in brightness. Spot it soon — before the Moon interferes — using our exclusive sky charts.
Complete guide to Friday night’s triple shadow transit of Jupiter’s moons and a remarkable “pre-game” show of mutual events.
Astronomers say that a once-in-26-year eclipse, predicted to occur in January, probably happened months ago without anyone seeing it.
