This photo of periodic comet Churyumov-Gerasimenko (67P) was taken on November 7, 2021 by Rolando Ligustri (CARA Project, CAST). The comet's tail seems to stretch past Pollux, one of the twins of the constellation Gemini.
Comet 67P is commonly known as Rosetta's comet because the Rosetta probe met up with the comet in deep space and orbited it as it moved into the inner Solar System and around the Sun. The mission ended with Rosetta joining its lander Philae on the comet. So this comet is unique in carrying something of Earth on its travels.
One of my favorite astrophotographers is award-winning Mark Gee, who lives in New Zealand near some of the world's darkest skies. Today's photo was taken in Pukerua Bay with a rugged landscape and magnificent sky.
Gee says that “astrophotography ... is one of the most rewarding forms of photography there is. .. it has certainly been one amazing journey of self discovery for me, and I am very humbled to be able to share these images with you”.
A cosmic drama, captured by the Hubble Space Telescope, looks like a fiery blue sword has transfixed a giant heart.
The photo is of Herbig-Haro object HH111, some 1300 light years away in Orion. A new star is forming, and the “sword” is twin jets of superheated gas from opposite poles of the infant star. Some leftover dust and gas surrounding the star makes up the “heart”.
. Angie, they tend not to say when an image was actually caught by the telescope. And there's then going to be a certain amount of checking & processing when the data arrives. Not everything gets super processing into classy images. But I can say that the release date of the photo from the Hubble people was August 20 of this year.
The Atacama Large Millimetre Array (ALMA) is an astronomical telescope made up of an array of 66 giant antennas. Combinations of the antennas are used as an interferometer. This allows it a much wider field of view than the dish of an ordinary radio telescope. ALMA can make precision observations beyond the ability of many other telescopes.
The telescope is located on the Chajnantor plateau at an elevation of 5,000 m (16,000 ft). Chajnantor means "place of departure" in the Kunza language of the Atacameño people that lived there and named this plateau. [Photo: Yuri Beletsky]
Canadian Brian Ventrudo of “Cosmic Pursuits” had a wonderful experience early in November when “the morning radio show announced. . .that a brilliant display of aurora borealis was underway and visible from nearly everywhere in the city." [Calgary]
Despite subzero temperatures, he was off with his camera into his backyard. “It was the most spectacular auroral display this far south for the past decade & one of the best I've seen in nearly three decades.”
The amazing spiral in the star system LL Pegasi isn't an artist's creation. It's an infrared image taken by the Hubble Space Telescope. No one is certain about the origin, but it's probably due to a binary star system going into its planetary nebula phase, ejecting the outer atmosphere. The glow is likely to be light reflected from nearby stars.
