Much closer than the last entry, NGC 5248 is a spiral galaxy about 69 million light years away in the constellation of Boötes, the Herdsman. Discovered by William Herschel (1738-1822) in 1784, this galaxy is best seen through a telescope in the late spring in the northern hemisphere.

So I thought I would start a galaxy character thing tonight.

I'm going to pull pictures from Nasa and draw a character (tonight)

I zoomed in on it.

If you wanna join in that would be awesome! I'm going to try and keep it at an hour.

Tag me or show me what you make!

Galaxy OC challenge for fun!

Here's the article I pulled it from.

A new study has shown that an mRNA vaccine protected mice against deadly intestinal C. difficile

- By Nuadox Crew -

Researchers have developed an mRNA vaccine targeting Clostridioides difficile (C. difficile), a severe intestinal pathogen responsible for about 30,000 deaths annually in the U.S.

This new vaccine showed promising results in mice, offering protection from severe illness and death after exposure to lethal doses of the bacteria.

Unlike conventional vaccines, the mRNA version triggered a broad immune response, including antibodies and T cells. Vaccinated mice survived, experiencing only mild symptoms, and maintained immunity for six months.

While the vaccine has yet to be tested on humans, early studies in rhesus macaques suggest it might also elicit an immune response in primates.

However, more research, including testing on "dirty mice" with more naturalistic immune systems, is needed before moving to human trials.

NGC 5248, C45 // Greg Nelson

NGC 5248 is notable for the ring structure around its central region. These nuclear rings have hot spots of star-formation activity, called starbursts. Because NGC 5248 is so close to Earth (compared to other galaxies with these features), it offers a great chance to study how these starbursts happen and progress.

Lose yourself in 50 breathtaking new images released for the Hubble anniversary

Lose yourself in 50 breathtaking new images released for the Hubble anniversary

In April of 1990, our Universe opened up to us in a whole new way.

That’s when the Hubble Space Telescope was launched and deployed, the most powerful space telescope ever created.

Although the instrument got off to a bumpy start, Hubble has, as of April this year, been in operation for a full three decades. And, in celebration of this marvellous milestone, NASA has just handed us space riches: 50 newly processed images of objects from the Caldwell catalogue, released to the public for the first time.

Cosmic objects can be categorised in many different ways. What makes the Caldwell catalogue special is that it contains only objects that can be observed by backyard astronomers. Grab a telescope (or, in some cases, your own two eyes), and you can find these objects for yourself in the night sky.

The Caldwell catalogue, compiled by amateur astronomer and writer Sir Patrick Alfred Caldwell-Moore, was first published in 1995 in Sky & Telescope, intended as a complement to the Messier catalogue of 110 objects compiled by French astronomer Charles Messier in the 18th century.

Messier, famously, compiled his catalogue out of frustration. He was interested in finding comets; the catalogue was a list of annoying things that weren’t comets, and that could therefore be safely ignored by comet hunters.

Ironically, it turned out to be a really useful list of bright targets for amateur astronomers to look at, including nebulae, star clusters, and nearby galaxies.

The Caldwell catalogue, containing 109 objects, consists of 28 nebulae, 46 clusters, and 35 galaxies that were not included in the Messier catalog, but are still of intense interest for anyone who enjoys looking skyward at night.

There’s a joy to be had in finding these objects yourself, and in seeing them, light-years away, with your own eyes. There’s also joy in comparing your own observations to what Hubble has seen with its much more powerful “eye”. And, well, they’re just glorious.

Thirty Caldwell objects feature in the 50 new NASA images, with some objects appearing in more than one image.

“Because of Hubble’s detailed field of view, some of its pictures do not capture the entirety of a Caldwell object, sometimes instead zooming in on clusters of young stars in the arms of a spiral galaxy, stars on the outskirts of a cluster, or the zombie star at the heart of a nebula,” wrote Vanessa Thomas of NASA’s Goddard Space Flight Center on the NASA website.

“But in other cases, a mosaic of Hubble observations assemble to create a complete or nearly complete portrait of the celestial marvel.”

In total, Hubble’s Caldwell catalogue – first published in December of 2019 – now includes 87 of the 109 Caldwell objects. The space telescope hasn’t ignored the Messier catalogue, either; Hubble has imaged 96 of the 110 Messier objects. Each object in both catalogues includes a viewing guide for how to see it in the sky.

Together, the two collections contain some of the most breathtakingly beautiful images of the space around us – an awe-inspiring tour of the wonders of the cosmos.

And an absolute testament to the priceless treasure Hubble has turned out to be.

You can peruse more stunning pics in the full Caldwell collection and Messier collection on the NASA website.

Европейская Южная Обсерватория (ESO) опубликовала великолепный снимок галактики с обозначением NGC 5248, которая также известна под имене�� Caldwell 45.

Здесь и ниже изображения ESO

Названная структура находится на расстоянии приблизительно 59 млн световых лет от нас в созвездии Волопаса. Особенность галактики заключается в том, что около её центра находится не одно, а сразу два кольца звёздообразования. Здесь новые светила зарождаются с очень высокой скоростью.

Представленная фотография получена с помощью приёмника MUSE (Multi Unit Spectroscopic Explorer), который установлен на Очень Большом Телескопе ESO (VLT). Это уникальный инструмент для исследования космического пространства. Он включает в себя 24 спектрографа, разлагающие свет на составляющие с разными длинами волн и способные создавать как изображения, так и спектры избранных участков неба. Одна из функций прибора — создание трёхмерных изображений космических объектов, в которых на каждом пикселе третьим измерением является спектр.

На снимке NGC 5248 отчётливо просматриваются спиральные рукава, закручивающиеся против часовой стрелки. Области интенсивного звёздообразования показаны оранжевым цветом.

Добавим, что информация, полученная с MUSE, даёт новый взгляд на очень слабые и далёкие галактики, видимые в эпо��у зарождения Вселенной около 13 миллиардов лет назад. Приёмник регистрирует галактики в 100 раз более слабые, чем удавалось зарегистрировать в прежних обзорах.
