Few meteor showers are a cascade of shooting stars. Sky & Telescope contributing editor David H. Levy explains that there's simple pleasure in paying attention to sparser showers.
Step outside as evening twilight fades, and you’ll find brilliant Venus, along with fainter Mars and Saturn, shining low in the west.
Astronomers report that a nearly forgotten meteor shower — famous for its prodigious "storm" in 1872 but long since inactive — has displayed surprising activity.
Japanese observer Masayuki Tachikawa appears to have captured another impact on Jupiter, the second one in the past three months.
When observers fanned out last July 19th to record a binary asteroid's passage across a distant star, they hoped to gain scientifically important new findings. The results are in, and they've scored big-time!
Truly dedicated eclipse-watchers — who live in the Eastern Hemisphere — have a chance to watch the Moon barely graze Earth's umbra during the first eclipse of 2013.
North Americans haven't seen a total eclipse of the Moon since 2011. But this long dry spell breaks late on the night of April 14–15 as the Moon makes a leisurely pass through Earth's deepest shadow.
On February 15th, a 150-foot-wide rock will make the closest pass by Earth of any asteroid predicted far in advance. You may be able to follow it in a telescope.
Asteroid 2011 MD is expected to pass less than 8,000 miles above Earth's surface around 1 p.m. EDT (17:00 UT) on Monday.
For the second time this year, skywatchers the world over are celebrating Astronomy Day. If the sky is clear this weekend, you'll be treated to a bounty of late-summer stars and planets.
If you're up for a bit of a challenge, drag out your telescope to watch a thin crescent Moon glide over brilliant Venus. This cover-up is a daylight event in the U.S., but it occurs in dark skies before dawn on the 14th for lucky observers in Japan.
UPDATE: No significant auroras were reported Thursday morning following the Sun's whopper coronal mass ejection on January 7th. But there's still some chance of a mid-latitude light show as the hours go by.
For the second time in six months, the Sun has graced Down Under with an eclipse. Only a lucky few caught this annular eclipse, which traversed sparsely populated northern Australia.
Mercury's best evening apparition of 2011 for Northern Hemisphere observers takes place this March. And with Jupiter to point the way, Mercury is unusually easy to locate from March 1218.
One of the big planet's iconic dark belts has been roiling with activity, rewarding observers with the most dramatic eruptions there since 1926.
This week's visit by asteroid 1998 QE2 is just a courtesy call, as it passes by on May 31st at 15 times the Moon's distance. A NASA radar team has already discovered that this big space rock has a sizable companion.
On what's become the busiest shopping day of the year, a deep partial solar eclipse swept across the bottom of the world.
Amateur astronomers have spotted a brief flare of light on Jupiter, the third such explosion in as many years. The impactor was too small to penetrate deeply enough into the Jovian upper atmosphere, and no impact "scar" has been seen.
A newfound visitor from the solar system's icy fringe could brighten a millionfold by mid-September 2011 and become a pretty sight in the predawn sky.
An exploding star in the galaxy M74 in Pisces, discovered on July 25th, peaked at magnitude 12.5 in mid-August and was still V magnitude 13.2 as of September 5th.
Mars is making its nearest and brightest appearance in the night sky since the end of 2007.
It won't be easy by a long shot, but it just might be possible to spot the comet in broad daylight as it passes nearest the Sun.
The Delta Aquariid meteor shower ramps up in late July, and you already have everything needed to enjoy the show: your eyes.
Ceres, the biggest asteroid and the first to be discovered, has an extraordinary good apparition in February and March 2009.
Mercury is normally elusive, but it's putting on an extraordinarily good evening show for observers at mid-northern latitudes from late April through mid-May 2008.
