For sunwatchers who've been disappointed by this weak solar maximum, Active Region 2339 offers something to cheer about.
The three brightest planets — Venus, Jupiter, and Saturn — grace our evening skies this month. Elusive Mercury makes a brief appearance too!
A 6th-magnitude nova erupted inside the Sagittarius Teapot and reached 4th magnitude. Now it has started fading.
Although typically weak, the annual Lyrid display will benefit from moonless skies. This year's peak, late on April 22nd, favors Europe over North America.
Amateur skygazers can satisfy their celestial cravings with Globe at Night, International Dark-Sky Week, Astronomy Day, and Global Astronomy Month.
In a borderline eclipse of the Moon like last Saturday's, the difference between "total" and "partial" depends on some crucial assumptions.
Most sources say April 4th's lunar eclipse will be total, though only barely so. However, those calculations have overlooked a subtle factor that might render the event only "partial."
An unusually brief total eclipse of the Moon will be visible before dawn this Saturday, April 4th, from western North America. The eclipse happens on Saturday evening for Australia and East Asia.
There's much to take in during Saturday morning's total lunar eclipse, including a rare Moon-galaxy pairing, the splendid summer Milky Way, and a chance to see your shadow reach all the way to the Moon.
The stars of northern winter linger in the west as celestial bears, a lion, and a snake climb in the east. Meanwhile, Jupiter and Venus sparkle overhead.
With risky prospects on far-northern islands and at a premium aboard aircraft, observers looked on with awe as the Moon's shadow swept across the Arctic Ocean
As the countdown for Friday's total solar eclipse nears zero, "umbraphiles" from around the world are flocking to remote parts of the far north in the hope of finding clear skies.
A 6th-magnitude nova has erupted inside the Sagittarius Teapot. It may (or may not) still be brightening.
Follow Comet Lovejoy high overhead while you still can. Use our February finder chart below. The comet is fading more slowly than expected.
When the Moon next covers the Sun, on the equinox, its hard-to-reach path will include the North Pole but very little land.
As we transition between seasons, Orion rides high in the evening sky — easily found by spotting the row of three bright stars in his Belt.
Two total lunar eclipses occur this year, on April 4th and September 27−28. Meanwhile, a total solar eclipse in March sweeps across remote Arctic waters on March 20th, and a partial event on September 13th is likewise poorly placed for observing. Any list of nature's grandest spectacles would certainly include eclipses of the Sun...
Earth's two closest planetary neighbors draw strikingly close together this week.
Jupiter reaches opposition on February 6, 2015. Find out how to see the planet king at its best.
Some of the prettiest nighttime sights involve the close pairing of two solar-system bodies, and February features events with the Moon and Jupiter, then Venus and Mars.
The new Comet Lovejoy, C/2014 Q2, should brighten from 5th to 4th magnitude from late December through January as it climbs into excellent viewing position for the Northern Hemisphere, high in the dark winter sky.
Sky & Telescope's year-at-a-glance guide to celestial happenings is a symphony of detailed calculations and clear, elegant design.
Has Comet Q2 Lovejoy stoked you to see more of these celestial travelers? We look into the crystal ball to see what's coming in 2015.
With a small telescope and our sky charts, you can watch the sizable near-Earth asteroid 2004 BL86 race among the stars on the night of January 26–27.
Get your scope ready for a rare event this Friday night when one after another three of Jupiter's brightest moons and their shadows parade across its face.
