The Gamma Cygni Nebula
Supergiant star Gamma Cygni is at the center of the Northern Cross. Near the plane of our Milky Way galaxy, that famous asterism flies high in northern summer night skies in the…
Good Morning Planets from Chile
On June 15, innermost planet Mercury had wandered about as far from the Sun as it ever gets in planet Earth's sky . Near the eastern horizon just before sunrise it stands over…
Strawberry Supermoon from China
There are four Full Supermoons in 2022. Using the definition of a supermoon as a Full Moon near perigee, that is within at least 90% of its closest approach to Earth in a given…
In the Heart of the Virgo Cluster
The Virgo Cluster of Galaxies is the closest cluster of galaxies to our Milky Way Galaxy . The Virgo Cluster is so close that it spans more than 5 degrees on the sky - about 10…
Satellites Behind Pinnacles
What are all those streaks across the background? Satellite trails. First, the foreground features picturesque rock mounds known as Pinnacles. Found in the Nambung National Park…
M51: The Whirlpool Galaxy from Hubble
The Whirlpool Galaxy is a classic spiral galaxy. At only 30 million light years distant and fully 60 thousand light years across, M51 , also known as NGC 5194, is one of the…
Find the Man in the Moon
Have you ever seen the Man in the Moon? This common question plays on the ability of humans to see pareidolia -- imagining familiar icons where they don't actually exist. The…
The Road and the Milky Way
At night you can follow this road as it passes through the Dark Sky Alqueva reserve not too far from Alentejo, Portugal. Or you could stop, look up , and follow the Milky Way…
Arp 286: Trio in Virgo
This colorful telescopic field of view features a trio of interacting galaxies almost 90 million light-years away, toward the constellation Virgo . On the right two spiky ,…
Cosmic Clouds in Cygnus
These cosmic clouds of gas and dust drift through rich star fields along the plane of our Milky Way Galaxy toward the high flying constellation Cygnus. They're too faint to be…
Ship Tracks over the Pacific Ocean
What are those unusual streaks? Some images of planet Earth show clear bright streaks that follow the paths of ships. Known as ship tracks , these low and narrow bands are caused…
NGC 6188: Dragons of Ara
Do dragons fight on the altar of the sky? Although it might appear that way, these dragons are illusions made of thin gas and dust. The emission nebula NGC 6188, home to the…
Milky Way Galaxy Doomed: Collision with Andromeda Pending
Will our Milky Way Galaxy collide one day with its larger neighbor, the Andromeda Galaxy? Most likely, yes. Careful plotting of slight displacements of M31's stars relative to…
Two Black Holes Dancing in 3C 75
What's happening at the center of active galaxy 3C 75? The two bright sources at the center of this composite x-ray (blue)/ radio (pink) image are co-orbiting supermassive black…
Tau Herculids from Space
On May 31 tens of parallel meteor streaks were recorded in this 8 degree wide field of view of planet Earth's limb from space. The image is one of a series of 5 minute long…
A 10,000 Kilometer Galactic Bridge
With this creative astro-collaboration you can follow the plane of our Milky Way Galaxy as it bridges northern and southern hemisphere skies . To construct the expansive composite…
Lunar Occultation of Venus
On May 27 Venus rose as the morning star, near the waning crescent Moon in a predawn sky already full of planets. It was close on the sky to the Moon's crescent and a conjunction…
Tau Herculid Meteors over Kitt Peak Telescopes
It wasn't the storm of the century -- but it was a night to remember. Last night was the peak of the Tau Herculid meteor shower, a usually modest dribble of occasional meteors…
Rocket Transits Rippling Sun
The launch of a rocket at sunrise can result in unusual but intriguing images that feature both the rocket and the Sun. Such was the case last month when a SpaceX Falcon 9 rocket…
Red Crepuscular Rays from an Eclipse
What's happening behind that island? Things both expected and unexpected. Expected, perhaps, the pictured rays of light -- called crepuscular rays -- originate from the Sun .…
Simulation TNG50: A Galaxy Cluster Forms
How do clusters of galaxies form? Since our universe moves too slowly to watch, faster-moving computer simulations are created to help find out. A recent effort is TNG50 from…
RCW 86: Historical Supernova Remnant
In 185 AD, Chinese astronomers recorded the appearance of a new star in the Nanmen asterism. That part of the sky is identified with Alpha and Beta Centauri on modern star charts.…
Titan: Moon over Saturn
Like Earth's moon, Saturn's largest moon Titan is locked in synchronous rotation. This mosaic of images recorded by the Cassini spacecraft in May of 2012 shows its anti-Saturn…
NGC 4565: Galaxy on Edge
Magnificent spiral galaxy NGC 4565 is viewed edge-on from planet Earth. Also known as the Needle Galaxy for its narrow profile, bright NGC 4565 is a stop on many telescopic tours…
