Meteor Milky Way
25.11.1998

The bold, bright star patterns of Orion (right) are a familiar sight to even casual skygazers. But this gorgeous color photo also features a subtler spectacle - the faint stars of the Milky Way.

Forest and Sky
16.11.2007

With pine trees in dim silhouette, this skyscape from Breil-sur-Roya in southern France was captured on November 11. In the early evening scene, a satellite seems to streak through the branches, while bright, round, fuzzy Comet Holmes appears to lie just beyond them, near the stars of the constellation Perseus.

Aurigids from 47 000 Feet
5.09.2007

On September 1, Aurigid meteors filled the sky, in keeping with inovative predictions of an outburst from this historically tentative meteor shower. Astronomers flying at 47,000 feet on a dedicated mission to observer the outburst collected image data for this composite photo of the Aurigids' bright and colorful streaks.

Night Sky Highlights: March to May
13.03.2018

What might you see in the night sky over the next few months? The featured graphic gives a few highlights. Viewed as a clock face centered at the bottom, sky events in March fan out toward the left, April toward the top, and May toward the right.

A Circumhorizontal Arc Over Ohio
24.05.2014

Why would clouds appear to be different colors? The reason here is that ice crystals in distant cirrus clouds are acting like little floating prisms. Sometimes known as a fire rainbow for its flame-like appearance, a circumhorizon arc lies parallel to the horizon.

Leonid Sunrise
16.11.2000

Such beautiful things begin as grains of sand. Locked in an oyster a granule grows into an iridescent pearl, lustrous and lovely to behold. While hurtling through the atmosphere at 70 kilometers per second, a cosmic sand grain becomes an awe-inspiring meteor, its transient beauty displayed for any who care to watch.

Fireball in the Arctic
24.12.2017

Something very bright suddenly lit up the arctic -- what was it? The original idea was to take a series of aurora images that could be made into a time-lapse video. But when night suddenly turned into day, the astrophotographer quickly realized that he was seeing something even more spectacular.

A Leonid Meteor Explodes
17.11.2001

Last night and tonight, a lucky few may see a meteor explode. As our Earth passes unusually close to debris expelled from Comet Tempel-Tuttle, many sand-sized particles from this comet are entering and burning up in the Earth's atmosphere.

Geminid Fireball over Mount Balang
16.12.2014

This was a sky to remember. While viewing the Geminids meteor shower a few days ago, a bright fireball was captured over Mt. Balang, China with particularly picturesque surroundings. In the foreground, a sea of light clouds slowly floated between dark mountain peaks.

Meteors vs Supermoon
15.12.2016

Geminid meteors battled supermoonlight in planet Earth's night skies on December 13/14. Traveling at 35 kilometers (22 miles) per second, the bits of dust from the mysterious asteroid 3200 Phaethon that produce the meteor streaks are faster than a speeding bullet.
