The Northern Lights shine above the frozen surface of Lake Superior on the west coast of the Keweenaw Peninusla in a 10 shot panorama captured over the space of three hours at the start of this month. To wit:
At left, a faint band of Zodiacal light rises sharply from the horizon crossing Mars and the Pleides star cluster. Both the distant galaxy M31 and our own Milky Way shine above the greenish auroral arc. Navigational north pole star Polaris is centered above and accompanied on the right by the northern night’s most recognizable asterism, the Big Dipper. Terrestrial lights include markers for two breakwaters on the the horizon near the center of the scene.

Behold: spiral galaxy Messier 106 – a swirling disk of stars and gas dominated by blue spiral arms and red dust lanes near the nucleus. To wit:
The core of M106 glows brightly in radio waves and X-rays where twin jets have been found running the length of the galaxy. An unusual central glow makes M106 one of the closest examples of the Seyfert class of galaxies, where vast amounts of glowing gas are thought to be falling into a central massive black hole. M106, also designated NGC 4258, is a relatively close 23.5 million light years away, spans 60 thousand light years across, and can be seen with a small telescope towards the constellation of the Hunting Dogs (Canes Venatici).

A 360 degree panorama of Perseverance Valley on Mars taken last year by the Opportunity Rover. To wit:
The scene is composed of 354 individual images recorded through 3 different colour filters by the rover’s panoramic camera from May 13 through June 10, 2018. A few frames remain in black and white at the lower left though. Those were obtained through only one filter just before a dust storm engulfed Mars in June 2018, ultimately ending the solar-powered rover’s trailblazing 15 year mission. Just right of center, the annotation identifies Opportunity’s entry point to Perseverance Valley along the Endeavor crater’s western rim. The rover’s tracks begin there, extending from over the horizon toward the far right and its final resting spot on the Red Planet.

Two Bronze Whaler sharks captured locked in a cresting wave at Red Bluff off the North Australian coast by photographer Sean Scott.
Behold: NGC 6302, also known as the ‘bug’ or ‘butterfly nebula’ – a vast planetary dust cloud with a dying central star 4,000 light years from Earth in the Scorpion Constellation. This enhancement is based on an especially sharp image recorded by the Hubble Space Telescope in 2009. to wit:
Cutting across a bright cavity of ionized gas, the dust torus surrounding the central star is near the center of this view, almost edge-on to the line-of-sight. Molecular hydrogen has been detected in the hot star’s dusty cosmic shroud.
