This is the California Nebula,aka NGC 1499,in Perseus near the star Menkib,or Xi Persei,at bottom. While this is primarly an emission nebula,there is dust in the periphery forming some faint reflection nebulosity. The main nebula emits strongly in not only the red H-Alpha wavelength but also the blue-green H-Beta wavelength,thus the pink or magenta colour.

The Full Moon at the equinox, on March 20, 2019, reaching full phase only fours hours after the moment of the vernal equinox, and here captured rising very shortly before the moment of the Full Moon. I shot this while the Moon was still rising and in a deep blue sky, and tinted yellow from atmospheric absorption. Even so, this is a blend of short (for the Moon) and long (for the sky) exposures to capture the dynamic range.

The rising "supermoon" of July 12, 2022 embedded in the blue arc of Earth's shadow, rimmed by the pink Belt of Venus band of twilight colours, all over the badlands formations of Dinosaur Provincial Park on the Red Deer River in Alberta, Canada. The blue arc is the shadow of the Earth cast onto the atmosphere opposite the sunset point. The pink Belt of Venus is from red sunlight still illuminating the upper atmosphere, an effect that lasts only a few minutes at sunset or sunrise, and requires a very clear sky to show up, as it was this night.

Sulphur Worker at Kawah Ijen, Java, Indonesia. Kawah Ijen is a volcano with an active crater and acid lake in East Java, Indonesia. It is an unbelievable and unmissable destination for anyone visiting Java or Bali. Not only is the view on the 4km walk up to the craters edge impressive, but what goes on there is mind boggling. Walking down to the bottom of Kwah Ijen (Ijen Crater), hundreds of Indonesian men, many in flipflops, are mining sulphur from the heart of the volcano.

The Coma Berenices star cluster,aka Melotte 111,in the constellation of Coma Berenices,here in a field of view wide enough (7.5° by 5°) to frame it with some of the surrounding galaxies,in particular the edge-on galaxy NGC 4565 at lower left and NGC 4559 at upper left. Several other fainter galaxies are in the field,some between 12th to 14th magnitude,such as the tiny quartet of Box Galaxies at the extreme upper right corner. Melotte 111 is one of the nearer star clusters,being only 288 light years away. The field is similar to that of binoculars.

$One of a short series of images showing the development of an aurora display from a classic arc into a more complex pattern of concentric arcs and with loops and swirls. This was Feb 5, 2019 from the Churchill Northern Studies Centre. The outburst lasted only 5 minutes or so and might have been due to the Bz interplanetary field turning south briefly. After this series, the display faded and fractured into faint arcs and a diffuse glow across the sky.$

Verges, a small town in the Northeast of Catalonia (Spain), during Easter celebrates the Procession of Verges with skeletons dancing on the sound of a drum, Roman soldiers, known as the 'Manages', and a representation of the life and crucifixion of Jesus Christ.

Ten skeletons dance to the beat of a drum to remember that no one is exempt of death. The backdrop of the medieval walls and towers of Verges is key to this macabre staging.

It was closer the night before, but alas, there were clouds! Some light cloud this night added the glow.

13848468 - Sulphur Worker at Kawah Ijen, Java, Indonesia. Kawah Ijen is a volcano with an active crater and acid lake in East Java, Indonesia. It is an unbelievable and unmissable destination for anyone visiting Java or Bali. Not only is the view on the 4km walk up to the craters edge impressive, but what goes on there is mind boggling. Walking down to the bottom of Kwah Ijen (Ijen Crater), hundreds of Indonesian men, many in flipflops, are mining sulphur from the heart of the volcano.

A portrait of the infamous STEVE arc of hot flowing gas associated with an active aurora, here showing his distinctive pink colour and the fleeting appearance of the green picket fence fingers that often show up hanging down from the main arc. On this night the green fingers lasted no more than two minutes. STEVE = Strong Thermal Emission Velocity Enhancement, and is a river of hot gas flowing east to west equatorward of the main aurora band. STEVE appeared after the main Kp5-level aurora died down in activity to the north, typical behaviour for STEVE. He was visible for only 35 to 40 minutes,

The Big Dipper reflected in the still waters of the lake at Police Outpost Provincial Park, in southern Alberta, on September 26, 2016, with an aurora to the north at right. Only in autumn can one shoot the Dipper reflected in the water in the evening sky, as it is then riding low along the northern horizon. This is from a latitude of 49° N where the Dipper is circumpolar. It is also called the Plough in Great Britain.

A 300° panorama of an aurora from the Churchill Northern Studies Centre, in Churchill, Manitoba on February 26, 2022. This aurora was at Kp1 level (very low) and appeared only as featureless grey arcs to the eye. But the camera picked up unusual red colouration, and even some yellow-oranges, along with the more normal greens. The reds are odd for such a low-level aurora as the oxygen reds typically appear only when the aurora gets very active and energetic. The display did brighten more later this night when it took on the more classic green arcs, with occasional lower fringes of nitrogen pink

A small cuttlefish (Sepia officinalis) still in its egg, about 1 cm whole size. Eyes, head and tentacles are already perfectly formed and defined, this means that only a few days are left to hatch, although the little cephalopod is still connected to its yolk sac. This picture is part of a work that features a special Italian place, Numana, on the Adriatic sea, where very specific geographical conditions make this spot a realm for underwater macro subjects, pretty much like Philippines or Indonesia.
