The brilliant Comet Leonard put on a mesmerizing performance late last year when it streaked across the sky on Christmas Day. Expelled from the solar system shortly after, the celestial matter captivated photographers around the world during its brief stint of visibility, including Gerald Rhemann who captured the illuminated body as its gas tail disconnected from its nucleus and was swept away by solar wind. The incredibly rare and brief event also garnered Rhemann the top prize in this year’s Astronomy Photographer of the Year contest.
Hosted by the Royal Observatory Greenwich, the 14th-annual competition received more than 3,000 entries from 67 countries. This year’s collection includes a glowing, avian-like aurora over Murmansk Oblast and the International Space Station as it flies over the Apollo 11 moon-landing site—the latter was taken by Andrew McCarthy, whose galactic photos have been featured multiple times on Colossal.

It’s been two months since NASA unveiled the first images captured by the exceptionally powerful James Webb Space Telescope, and a pair of new composites taken by the observer’s infrared NIRCam showcase Jupiter’s aurora and unique characteristics in similarly striking detail.
Against a dark backdrop filled with hazy dots that are likely distant galaxies, the wide view features two of the planet’s moons, Amalthea and Adrastea, and its rings. According to the European Space Agency, which released the images, the dusty halos shown are one million times fainter than the gaseous mass they encircle.
For the close-up, astronomers applied three filters to the NIRCam to capture the tiny details of the largest planet in our solar system. Zeroing in on the Jovian atmosphere, the image shows two polar auroras shining through red hues, with brilliant greens and yellows swirling around. “A third filter, mapped to blues, showcases light that is reflected from a deeper main cloud. The Great Red Spot, a famous storm so big it could swallow Earth, appears white in these views, as do other clouds because they are reflecting a lot of sunlight,” the agency says.
Because the human eye can’t see infrared light, scientist Judy Schmidt collaborated with astronomers to make the planet’s details visible. (via Peta Pixel)

This week, the first images from NASA’s James Webb Space Telescope amazed and daunted us with their inordinately deep looks at the cosmos, particularly the shot of the glimmering star-forming region known as the “Cosmic Cliffs” of the Carina Nebula. The team over at the Catskills-based studio Nervous System translated this galactic masterpiece into a new, similarly expansive infinity puzzle intended to be tiled continuously, with no predetermined shape, start, or end. Similar to its other designs, this iteration includes four whimsy cuts in the shape of an astronaut, a shooting star, a satellite, and the gold mirrors of the groundbreaking telescope itself. Try your hand at puzzling together distant galaxies by picking up the 264-piece jigsaw from the Nervous System shop.

NASA’s James Webb Space Telescope unveiled its first-ever collection of high-resolution color images capturing an exceptional amount of detail about the universe. The instrument reaches deeper into the cosmos than any before.
Launched in December, Webb is the world’s largest and most powerful observer with the ability to view cosmic bodies like the atmospheres of exoplanets, or those outside our solar system, and some of the first galaxies to emerge following the Big Bang 13.5 billion years ago. The telescope is equipped with a host of near-infrared tools that will help visualize galactic phenomena and celestial bodies that are otherwise invisible to the human eye. Webb is capable of getting four times closer to the cosmological event than the Hubble Space Telescope, which helps scientists better understand how the universe has evolved since.
Preparation for the mission began in the 1990s, and the 6.7-ton telescope is currently focused on documenting planetary evolution and spectroscopic data about their chemical makeup, which involves targeting five cosmic objects: the gassy planet WASP-96 b that’s about 1,150 light-years away, the Southern Ring Nebula, Stephan’s Quintet galaxy, the SMACS 0723 galaxy clusters, and the 7,600 light-years away Carina Nebula with enormous stars that dwarf the sun.
The very first images include a stunning composite of SMACS 0723 as it appeared 4.6 billion years ago. Rich with glimmering galaxies, the composite comprises “a patch of sky approximately the size of a grain of sand held at arm’s length by someone on the ground,” administrators said in a statement. There’s also the mesmerizing Southern Ring Nebula, which is comprised of shells of dust and gas released by two dying stars, and Stephen’s Quintet, five glowing galaxies captured in Webb’s largest composite to date, reaching a size that would span approximately one-fifth of the moon’s diameter.
Perhaps the most stunning image from the first release of visuals is that of the star-forming region in the Carina Nebula, which shows what researchers refer to as “cosmic cliffs,” or what appears to be rugged, mountain-like forms that are actually the edges of immense gaseous activity. The tallest pinnacles of that celestial body are about seven light-years high.
Webb was designed to spend the next decade in space, however, a successful launch preserved substantial fuel, and NASA now anticipates a trove of insights about the universe for the next twenty years. Follow its movements with NASA’s tracker, Where is Webb?

Brilliant Phenomena and Galactic Skies Light Up the 2022 Astronomy Photographer of the Year Shortlist
Whether in the form of nebulae or starry galactic expanses, natural light continues to dominate Royal Museums Greenwich’s Astronomy Photographer of the Year competition (previously). The 14th annual contest garnered more than 3,000 submissions from 67 countries, and a shortlist of finalists contains stunning shots of a September harvest moon illuminating Glastonbury Tor, the brilliant streaks trailing Comet Leonard, and the vibrant Aurora Borealis casting an ominous glow above a battered ship in Westfjords.
Winning photos will be announced on September 15 with an exhibition opening at the National Maritime Museum on September 17. Until then, peruse the full collection on the Royal Museum Greenwich site.

In this collection of cosmic photographs, comets, nebulas, and galaxies stretch before the human eye, showering the sky in glittering scenes that ought to be from a telescope. But instead of looking upward into the night, Finnish photographer Juha Tanhua points his camera to the ground. He documents his “oil paintings” in broad daylight, shooting gasoline and oil spills usually found in car parks. “I don’t look up, but down,” he tells Colossal. “It’s not space above us; it’s space under our feet. You can find subjects to photograph even in dull places like parking lots. Expect nothing, get everything.”
The photographer first got his idea for the gasoline puddles when noticing an oil spill next to his car. “It looked a little bit like the northern lights,” he says. He forgot about the image, which he named “Urban Aurora Borealis,” until finding it months later when organizing an archive. After that, when walking around parking lots after heavy rain, he began to notice more leaks and started to document them. He now has hundreds in his collection. “I named them oil paintings,” he says. “Because it looked like artworks under cars.”
Tanhua likens rain to a brush, which “paints the artwork” and is an essential component in ensuring the stains don’t fade in the dry summer. Once captured, he plays with the exposure, editing the highlights, shadows, and contrasts of each image to gain the appearance of galactic matter from a combination of the oil patterns and the ground’s rough texture.“When I shoot against black asphalt and underexpose the image, the rocks on the asphalt turn into stars,” he explains.
Currently living in the small village of Vuolenkoski, near Lahti in Southern Finland, Tanhua obtained his first camera at age 15, when his father gifted him an Olympus 35 DC compact model that he purchased while working in Japan. In 1979, Tanhua began an apprenticeship at a local studio, which launched subsequent careers in journalism and later freelance photography. His works are now included in collections within the Finnish National Gallery and Lahti Art Museum. You can find more of his photos on his website. (via Peta Pixel)
