JWST Images The Lion's Head Nebula
Image Credit: NASA, ESA, CSA, STScI; Image Processing: Alyssa Pagan (STScI)

Are we looking at the future of our Sun? The James Webb Space Telescope captured today’s composite image of the Lion’s Head Nebula (NGC 2392) with its NIRCam and MIRI instruments. The Lion’s Head Nebula is the remnant of a Sun-like star. This star was unable to sustain the nuclear fusion in its core needed to remain stable. It began to shed layers of gas and dust into space, forming this planetary nebula. A hot stellar core, called a white dwarf, is left behind within the lion’s nose. Do not boop this nose! Intense radiation from the white dwarf is ionizing the gas as it expands, creating the irregular bubble that makes up the lion’s face. Dust clumps that have survived the white dwarf’s radiation and a cloud of ionized gas make up the lion’s mane. This new and more detailed view of the nebula will help humanity learn more about how the gas and dust interact with each other and the white dwarf radiation.

Earth's Shadow Visualized with Lunar Eclipses
Image Credit & Copyright: Tim Martin
What’s creating this giant hole in space? This is not a black hole — it’s a shadow. It’s Earth’s shadow. Since at least the time of Aristotle, people have noted that Earth's dark shadow on the Moon during a partial lunar eclipse is circular -- although never a whole circle. Using modern digital technology, though, the images of multiple lunar eclipses can be combined to show Earth's complete shadow. The featured image compilation by a persistent astrophotographer is constructed from 22 years of lunar eclipses. The Moon is not eclipsed every month (moon-th) because the Moon's orbit is slightly tilted relative to Earth's orbit. Close inspection of some lunar eclipse images shows a faint blue band where Earth’s atmosphere filters out more red sunlight than blue. Later this week, a new lunar eclipse will occur and will be best visible in parts of North and South America, Europe, and Africa.

Comet 220P in Outburst

Comet 220P is unexpectedly bright. Normally, periodic Comet 220P/McNaught is so dim that to see it requires a telescope. Two surprising outbursts this year, however, have made it about 20,000 times brighter than usual, so that it is now visible with binoculars and long-duration camera exposures. As expected, Comet 220P continues to orbit the Sun between Mars and Jupiter with a period of over 5 years. The featured long duration exposure, taken 10 days ago from South Africa, shows the comet's bright green head and short dust tail. Reasons for Comet 220P's impressive outbursts are unknown but could be caused by the release of built-up subsurface gas or comet quakes. Comet 220P will pass about one Earth-Sun distance from the Earth in October, after which it is expected to fade quickly as it begins its return to the far part of its orbit.

Cassini Approaches Saturn

What would it look like to approach the grand planet Saturn? One doesn't have to just imagine -- the Cassini spacecraft did just this in 2004, recording thousands of images along the way, and hundreds of thousands more since entering orbit. Some of Cassini's early images have been digitally tweaked, cropped, and compiled into the featured inspiring video which is part of a larger IMAX movie project named In Saturn's Rings. In the concluding sequence, Saturn looms increasingly large on approach as cloudy Titan swoops below. With Saturn whirling around in the background, Cassini is next depicted flying over Mimas, with large Herschel Crater clearly visible. Saturn's majestic rings then take over the show as Cassini crosses Saturn's thin ring plane. Dark shadows of the ring appear on Saturn itself. Finally, the enigmatic ice-geyser moon Enceladus appears in the distance and then is approached just as the video clip ends. After more than a decade of exploration and discovery, the Cassini spacecraft ran low on fuel in 2017 was directed to enter Saturn's atmosphere, where it surely melted.

Mostly Perseids
Image Credit & Copyright: Jakub Koukal (Valašské Meziříčí Observatory)
Recorded the night of August 12-13, images from four dedicated meteor-monitoring cameras at an astronomical observatory in Czechia were aligned and combined to create this all-night, all-sky view. On that night, the total count came to 1,706 meteors. And since that coincided with the peak activity of the 2026 Perseid Meteor Shower, most are perseids. Their overwhelming numbers make them easy to spot. Quite convincingly, perseid trails all trace back to a single radiant on the sky at the upper right, a region in the annual shower's eponymous constellation Perseus. But meteors belonging to other much less active showers can be revealed by finding their radiants too. For example, seen crossing the perseid trails are meteors from a shower whose radiant lies in Cygnus, known as Kappa Cygnids. The antihelion complex, a general region near Aquarius and opposite the Sun in the sky, is also identifiable as weak source for meteors.

Time-Lapse of the Star S301 Orbiting the Black Hole in the Center of the Galaxy

What does it feel like to zoom around a spinning supermassive black hole? The featured video is an animation showing a time-lapse of 4 years of observations of the star S301 orbiting Sagittarius A*, the 4-million-solar-mass black hole in the center of our Galaxy. S301 was discovered in 2023 with the Very Large Telescope Interferometer of the European Southern Observatory, located in the Atacama Desert in Chile. Astronomers recently found that S301 takes approximately 8.7 years to go around the black hole and reaches speeds of 25,000 km/s. It comes closer to the black hole than any other stars detected before, at a distance similar to that from Saturn to the Sun. Because it comes so close to Sagittarius A*, S301 could be used to directly measure how fast the black hole spins and test Einstein's theory of general relativity. According to the theory, a spinning black hole drags the fabric of spacetime around itself, affecting the orbits of close-by objects.

The Elephant's Trunk in Cepheus
Image Credit & Copyright: Eddie Sgarbossa
Like an illustration in a galactic Just So Story, the Elephant's Trunk Nebula winds through the emission region and young star cluster complex IC 1396, in the high and far off constellation of Cepheus. Also known as vdB 142, this cosmic elephant's trunk is over 20 light-years long. The detailed telescopic view features the bright swept-back ridges and pockets of cool interstellar dust and gas that abound in the region. But the dark, tendril-shaped clouds contain the raw material for star formation and hide protostars within. Nearly 3,000 light-years distant, the relatively faint IC 1396 complex covers a large region on the sky, spanning over 5 degrees. Top to bottom this proboscidean-like rendition reaches across an almost 1 degree wide field of view, though. That's a little less than the angular size of 2 full moons.

The Case of the Mysterious Maybe Meteor

Whatdunit? What disappeared while crossing a partially eclipsed Sun? Let’s present the evidence. The 24 frames-per-second video was taken in Spain (40°34'30.3"N 1°12'28.8"W) at 20:28 local time on August 12, 2026. The Perseids meteor shower was at its peak during this time. Is this a meteor? Meteor showers trace back to a region of the sky called a radiant point that corresponds to where the Earth is crossing a comet’s path. The object’s path might trace back to the Perseids’ radiant point in the Perseus constellation. The object trails a smaller angle on the sky than the 0.5 degree Sun and Moon, which is smaller than expected for a meteor. Its brightness does not extend much past the Sun, but a meteor burning up in the sky would not need sunlight to be seen. Perhaps the sunlight is reflecting off of the object? After cross-referencing the location, time, and point in the sky with a flight database, the culprit is found to be an airplane contrail!

Perseids from Perseus
Image Credit & Copyright: Jakub Kuřák
This was a good year for the Perseids meteor shower. A key reason was the Moon was absent from lighting up Earth's night sky so that more meteors were visible than usual. Where was the Moon? It was busy visiting the Sun. Near the Perseids peak, the Moon moved directly in front of the Sun and created a total solar eclipse visible from Greenland and Spain. The Perseids occur when the Earth collides with a stream of Sun-orbiting debris cast off by Comet Swift-Tuttle. Perseid meteors, although typically only the size of a sand grain, tend to be fast and bright because Swift-Tuttle's debris orbits the Sun in a direction partly opposite Earth's orbital motion. In the featured image compilation accumulated over several nights from Jizerka in the Czech Republic, the Perseids meteor streaks can be traced back to a single location on the sky -- its radiant in Perseus.
